Development of Soya Fortified High Protein Supplementary Biscuits

Soy flour biscuits represent a promising intersection of nutrition and taste, offering a delectable snack option with a robust nutritional profile. This abstract elucidates the nutritional value and health benefits of soy flour biscuits Soy flour, derived from soybeans, serves as the primary ingredient in these biscuits, imparting numerous health advantages. Soy flour is renowned for its high protein content, making it an excellent alternative for individuals seeking plant-based protein sources. Additionally, soy flour is rich in essential amino acids, including lysine, which is often limited in cereal grains. Furthermore, soy flour is a notable source of dietary fiber, aiding in digestive health and promoting satiety. The inclusion of dietary fiber enhances the biscuits' nutritional value, contributing to better weight management and improved blood sugar regulation.Moreover, soy flour contains a plethora of micronutrients, such as iron, calcium, and magnesium, crucial for various physiological functions, including bone health and oxygen transport. These nutrients fortify the biscuits, ensuring they offer a well-rounded nutritional profile. Incorporating soy flour biscuits into one's diet can confer several health benefits. Their high protein content makes them an ideal snack choice for individuals seeking to boost muscle mass or maintain weight. Moreover, the presence of dietary fiber can aid in managing cholesterol levels and promoting cardiovascular health.

PSV-19 Evaluation of Dietary Fiber Inclusion on Body Weight, Body Condition, Fecal Score, and Metabolic Indicators in Mature AI Boars

Abstract This experiment was conducted at the Purdue University swine research and education center. The objective of this study was to determine if the inclusion of fiber (8.48% vs 14.85% NDF) in the diet influenced boar body weight, backfat depth, loin depth, Knauer sow caliper measurement, flank to flank distance, and visual body condition score (BCS). Twenty-seven boars from two age groups (7 months and 18 months) and two genetic lines (maternal and terminal) were utilized over a 12-week period with 1 week before the study data serving as baseline for statistical analysis. Fecal samples were also taken and scored using the Bristol stool scoring system. Timepoints for sample collection were on weeks -1,3,7, and 11. Boars were blocked by age and breed and randomly allotted to receive 2.72 kg/d of corn-soybean meal diet (CON, n = 13) formulated to meet NRC (2012) requirements or an isocaloric (estimated ME = 3,285 Kcal/kg) corn-soybean meal diet with 14.3% soyhulls and supplemental choice white grease (4.65%) inclusions (FIBER, n = 14). Data were analyzed using PROC GLM in SAS 9.4 (Cary, North Carolina) with boar serving as the experimental unit. Weeks were analyzed individually and changes in body weight, backfat depth, loin depth, caliper measurements, flank to flank distance, and BCS were evaluated from week -1 to week 12. Significance was determined at P < 0.05 and a trend was observed at 0.05 < P ≤ 0.10. FIBER boars gained 8.4 kg more than CON boars during the 12-week study (P = 0.0221). On weeks 3 and 11, FIBER boars tended to have increased backfat depth compared with CON boars (P < 0.0950), resulting in FIBER boars gaining 2.9 mm more backfat compared with CON (P = 0.0053) over the 12-week study. No difference in loin muscle depth was observed between treatments. On weeks 7 (3.7 vs 3.4, P = 0.0923) and 11(3.9 vs 3.5, P = 0.0615) FIBER boars tended to have greater BCS score compared with Con boars. FIBER boars on week 11 tended to have larger tape measurements (105.9 cm vs 103.9 cm, P = 0.0945) and larger caliper score (19.4 vs 17.6, P = 0.0029) than CON boars, but no difference in overall 12 week change for both measurements. FIBER boars tended to have softer stools during week 3 of the trial compared with CON boars (P = 0.0535), but the fecal scores were not different at any other week. Overall, boars fed a high fiber diet had increased body weight, backfat depth and BCS indicating an underestimation of the net energy value of soyhulls in limit fed boars. Future research is needed with varying levels and types of fiber inclusion in the diet to understand how to correctly implement fiber into the boar diet and to refine the net energy values of fibrous feedstuffs like soyhulls for boars.

PSV-20 Evaluation of Dietary Fiber Inclusion on Semen Production and Semen Characteristics in Mature AI Boars

Abstract This experiment was conducted at Purdue University swine research and education center. The objective of this study was to determine if the inclusion of fiber (8.48% vs 14.85% NDF) in the diet of boars influenced semen characteristics, concentration, motility, and morphology. Twenty-seven boars from two age groups (7 months and 18 months) and two genetic lines (maternal and terminal) were utilized in this study over a 12-week period with one week before the study data serving as a baseline for statistical analysis. Boars were blocked by age and breed and randomly allotted to receive 2.72 kg/d of corn-soybean meal diet (CON, n=13) formulated to meet NRC (2012) requirements or an isocaloric (estimated ME = 3,285 Kcal/kg) corn-soybean meal diet with 14.3% soyhulls and supplemental choice white grease (4.65%) inclusions (FIBER, n = 14). Semen was collected once per week per boar using the gloved hand method. While at the farm 3 mL of semen was mixed with 27 mL of extender (Androhep Plus, Minitube) to make a 1:10 dilution. The semen was then driven approximately 19 km to Purdue University where concentration (Nucleocounter SP-100), motility (Computer Assisted Sperm Analysis, CASA, CEROS II), and sperm cell morphology were analyzed. Statistical analyses were conducted using PROC MIXED in SAS 9.4 (Cary, NC), with the main effects of diet, age, and breed with week as a repeated measure. Significance was determined at P < 0.05 and a trend was observed at 0.05 < P ≤ 0.10. Fiber in the diet did not affect any semen characteristics throughout the study. However, the percent morphologically normal sperm was greater in young boars compared with the older boars (80.6% vs 74.1%, P = 0.0143) resulting from fewer head/tail abnormalities (1.8% vs 2.4%, P = 0.0249) and distal droplets (7.2% vs 9.6%, P = 0.0508). Maternal boars had fewer proximal droplets (6.9% vs 9.9%, P = 0.0325) and tended to have fewer head/tail abnormalities (1.8% vs 2.3%, P = 0.0800). Terminal boars tended to have fewer distal midpiece reflex abnormalities than maternal boars (3.3% vs 4.8%, P = 0.0948). Overall feeding boars a high fiber diet had no effect on semen characteristics; however there were effects of age and breed of boar on semen characteristics. Future research is needed with varying levels and types of fiber inclusion in the diet along with differing ages and breeds of boars to better understand how fiber may impact semen characteristics.

Broiler chicken response to xylanase and fermentable xylooligosaccharide supplementation

A study was conducted to determine the effect of dietary fiber (DF), xylanase (XYL), xylooligosaccharides (XOS), and a combination of XYL and xylooligosaccharides (STBIO) on chicken growth performance, N-corrected apparent metabolizable energy (AMEn), and nutrient availability, characteristics of the gastrointestinal tract (GIT), and cecal content of short-chain fatty acids (SCFA). A 35-day experiment was performed on 1,920 as hatched Ross 308 broiler chicks, reared in 96 pens and fed ad libitum. Experimental diets were split into 2 phases: starter (0-21 d) and finisher (22-35 d). There were 2 basal diets, first contained 54% maize and in the second, 5% of the maize was replaced by wheat bran as DF. The diets were split into 4 batches: one of them was used as a control, and each of the others were supplemented either with XYL or XOS or with the STBIO. Each diet was fed to 12 pens following randomization. The data were analyzed in GenStat (20th edition) by ANOVA using a 2×4 factorial design. The addition of STBIO improved feed conversion ratio (FCR) and increased weight gain (WG) from 21 to 35 d and from 0 to 35 d (P < 0.05). The inclusion of DF had a negative effect on N and fat retention coefficients at 35 d as well as AMEn and dry matter retention at 21 and 35 d. At 21 d, neutral detergent fiber (NDF) retention was increased when xylanase and STBIO were added to the diet (P < 0.001) and at d 35 the highest retention was noted when the diet was supplemented with DF and XYL or STBIO (P=0.001). There was no dietary effect on jejunum histomorphometry (P > 0.05). The addition of DF increased the concentration of cecal SCFA in particular valeric and propionic acid at 35-day-old birds (P < 0.05). It can be concluded that addition of STBIO in diet could provide benefits in terms of fiber degradation, WG, and feed efficiency.

A dynamic model to measure retention of solid and liquid digesta fractions in chickens fed diets with differing fibre sources.

Dietary fibres impact multiple digestive processes, and insights into the effects of various types of fibre on digesta retention time are required to optimise current feed formulation systems. Therefore, the objective of this study was to apply a dynamic modelling approach to generate estimates for the retention time of solid and liquid digesta in broilers fed different fibre sources. A maize-wheat-soybean meal control diet was compared against three diets in which wheat was partially substituted with oat hulls, rice husks, or sugar beet pulp (3% w/w). Non-starch polysaccharide (NSP) digestibility was evaluated in broilers between 23 and 25days of age (n=60 birds/treatment) using titanium dioxide (TiO2, 0.5g/kg) as a marker, after feeding the experimental diets for 21days. Digesta mean retention time (MRT) was measured in another 108 birds at 30days of age by the administration of an oral pulse dose of chromium sesquioxide (Cr2O3) as solid marker and Cobalt-EDTA as liquid marker, and subsequent measurement of marker recovery in compartments of the digestive tract (n=2 or 3 replicate birds/time point/treatment). Marker recovery models to estimate fractional passage rates for solid and liquid digesta in crop, gizzard, small intestine, and caeca compartments of the gastrointestinal tract were developed to predict MRT of solid and liquid digesta for each dietary treatment. The models were composed of a series of first-order differential equations, representing the variation of marker concentration in a compartment over time. Estimated MRT of solid and liquid digesta in the gizzard varied from 20min for oat hulls and 34min for rice husks diets to 14min for sugar beet pulp and 12min for control diets. In the caeca, liquid MRT was decreased compared to the control diet (989min) for the sugar beet pulp diet (516min), while it was increased for both the oat hulls and rice husks diets (≈1 500min). Overall, these estimates are greater than those previously reported, suggesting that liquid digesta retention in the caeca previously has been underestimated. Digestibility of total NSP was increased by dietary fibre inclusion, regardless of the fibre type, although degradation of constituent sugars of NSP varied among diets. In conclusion, the inclusion of fibre sources at a low level (3% w/w) in the diet of broiler modulated retention time mainly in the gizzard and caeca, and increased digestibility of NSP.

Correction of intestinal microbial composition disturbances as a potential link in complex therapy of patients with COVID-19

The article reflects the potential for correcting intestinal microbiota disorders in the complex therapy of patients with COVID-19. It has been noted that the inclusion of dietary fiber in the diet contributes to protection against disruption of the integrity of the intestinal barrier and may limit bacterial translocation into the systemic circulation. The possibility of using psyllium (Mucofalk) is reflected, the action of which is realized both through its sorption, cytoprotective and anti-inflammatory properties in viral lesions of the gastrointestinal tract, and through stimulation of the own beneficial intestinal microbiota. The paper presents studies of the prospects for the use of probiotics, synbiotics in the complex therapy of patients with COVID-19. Detailed data are provided on the mechanisms of the positive effect of short-chain fatty acid preparations on reducing the severity of the disease in patients with COVID-19. It was noted that taking the drug Zacofalk leads to a significant increase in its own butyrate-producing microbiota (Faecalibacterium prausnitzii) and suppression of the growth of opportunistic flora with pro-inflammatory activity. The results of a recent study are presented showing that in patients with a mild course of COVID infection with respiratory and intestinal symptoms, the administration of Zakofalk for 30 days (3 tablets per day) led to significantly faster stool normalization (by day 7), persistent normalization of the frequency and consistency of stools by the 21st day and a significantly more pronounced regression of bloating and abdominal pain, as well as a decrease in the risk of developing post-infectious irritable bowel syndrome.

Xylan alleviates dietary fiber deprivation-induced dysbiosis by selectively promoting Bifidobacterium pseudocatenulatum in pigs

BackgroundLow dietary fiber intake has been shown to disturb the gut microbiome community, damage the mucus barrier, and promote pathogen susceptibility. However, little is known about the temporal response of the gut microbiome to dietary fiber deprivation and the recovery induced by dietary fiber inclusion in pigs.ObjectiveIn the present study, temporal responses of ileal and fecal microbiota to dietary fiber deprivation were profiled using an ileum cannulated growing pig model. In addition, the potential of dietary-resistant starch, β-glucan, and xylan to alleviate gut dysbiosis throughout the gastrointestinal tract, as well as its possible mechanisms were investigated.MethodsSix cannulated growing pigs were fed a fiber deprivation diet for 35 days. Ileal digesta and feces were collected at days 0, 7, 21, and 35 for 16S rRNA sequencing and short-chain fatty acid (SCFA) determination. Another twenty-four healthy growing pigs were assigned to one of four dietary treatments including (1) fiber-free diet, (2) resistant starch diet, (3) β-glucan diet, and (4) xylan diet. These twenty-four pigs were fed a corresponding diet for 35 days and slaughtered. Gut microbiome and SCFA concentration were profiled along the gastrointestinal tract.ResultsDietary fiber deprivation-induced consistent microbiota extinction, mainly Bifidobacterium and Lactobacillus, and decreased SCFA concentrations in both ileum and feces. The community structure partially recovered at day 35 compared with baseline while SCFA concentrations remained low. Xylan supplementation alleviated gut dysbiosis by selectively promoting Bifidobacterium pseudocatenulatum within the large intestine. SCFA concentration increased significantly after xylan supplementation and exhibited a positive association with B. pseudocatenulatum abundance. An elevated abundance of xylan degradation-related enzyme genes was also observed in the gut microbiome after xylan supplementation. In vitro growth assay further verified the xylan utilization capacity of B. pseudocatenulatum.ConclusionsDietary fiber deprivation could induce probiotic extinction and loss of the SCFA production while potential pathogen was promoted. Xylan intervention could partially restore dietary fiber deprivation-induced gut dysbiosis through selectively promoting B. pseudocatenulatum and therefore normalizing the gut environment. These findings collectively provide evidence that dietary fiber-driven microbiota metabolism bridges the interplay between microbiome and gut health.DsGU9NsKuPME7_kAmChQecVideo abstract

Inulin and isomalto-oligosaccharide alleviate constipation and improve reproductive performance by modulating motility-related hormones, short-chain fatty acids, and feces microflora in pregnant sows.

Constipation in gestating and lactating sows is common and the inclusion of dietary fiber may help to alleviate this problem. We investigated the effects of inulin (INU) and isomalto-oligosaccharide (IMO), two sources of soluble dietary fiber, on gastrointestinal motility-related hormones, short-chain fatty acids (SCFA), fecal microflora, and reproductive performance in pregnant sows. On day 64 of gestation, 30 sows were randomly divided into three groups and fed as follows: a basal diet, a basal diet with 0.5% INU, and a basal diet with 0.5% IMO. We found that INU and IMO significantly modulated the levels of gastrointestinal motility-related hormones, as evidenced by an increase in substance P (P < 0.05), and a decrease in the vasoactive intestinal peptide concentrations (P < 0.05), indicating the capacity of INU and IMO to alleviate constipation. Furthermore, IMO enhanced the concentrations of acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids in the feces (P < 0.05). High-throughput sequencing showed that IMO and INU increased the fecal microflora α- and β-diversity (P < 0.05). Methanobrevibacter was more abundant (P < 0.05), whereas the richness of Turicibacter was lower in the INU and IMO groups than in the control group (P < 0.05). In addition, IMO significantly increased litter size (P < 0.05). Overall, our findings indicate that INU and IMO can relieve constipation, optimize intestinal flora, and promote reproductive performance in pregnant sows.

Dietary fiber as modulators of gastrointestinal hormonal peptide secretion

The review provides information on the effect of dietary fibers on the production of key gastrointestinal hormonal peptides that affect eating behavior and the formation of feelings of hunger and satiety. The mechanisms of action of dietary fiber on the production of appetite-regulating peptides are discussed. Modulation of gastrointestinal hormonal peptide secretion by dietary fibers is involved in the regulation of the balance of energy, appetite, and body weight. The aim of the research was to expand the understanding about the effects of dietary fiber on the secretion of major gastrointestinal hormonal peptides involved in appetite control, the formation of feelings of hunger, satiety and satiation. Results. Gastrointestinal hormones, as physiological regulators of food intake, play an essential role in the formation of feelings of hunger, satiety and satiation, helping to reduce appetite and maintain normal body weight. Various dietary fibers, depending on the physic-chemical properties, the amount and duration of the consumption period, can have a modulating effect on the secretion of the hunger hormone ghrelin and the hormones of satiety: leptin and intestinal peptides (glucagon-like peptide-1, cholecystokinin and YY peptide). Conclusion. Dietary fiber influence on processes of energy intake, food ingestion and nutrient absorption in gastrointestinal tract, enhance neuroendocrine responses, modulate release of appetite-regulating hormones involved in energy balance and regulation of feelings of hunger and satiety. The possibility to promote a favorable profile of the endogenic gastrointestinal hormones by inclusion of dietary fiber in food ration both in the form of the natural food and additionally as dietary supplements is of interest as one from strategies of over appetite control and normal body weight maintenance.

Changes in dietary fiber intake in mice reveal associations between colonic mucin O-glycosylation and specific gut bacteria

ABSTRACT The colonic mucus layer, comprised of highly O-glycosylated mucins, is vital to mediating host-gut microbiota interactions, yet the impact of dietary changes on colonic mucin O-glycosylation and its associations with the gut microbiota remains unexplored. Here, we used an array of omics techniques including glycomics to examine the effect of dietary fiber consumption on the gut microbiota, colonic mucin O-glycosylation and host physiology of high-fat diet-fed C57BL/6J mice. The high-fat diet group had significantly impaired glucose tolerance and altered liver proteome, gut microbiota composition, and short-chain fatty acid production compared to normal chow diet group. While dietary fiber inclusion did not reverse all high fat-induced modifications, it resulted in specific changes, including an increase in the relative abundance of bacterial families with known fiber digesters and a higher propionate concentration. Conversely, colonic mucin O-glycosylation remained similar between the normal chow and high-fat diet groups, while dietary fiber intervention resulted in major alterations in O-glycosylation. Correlation network analysis revealed previously undescribed associations between specific bacteria and mucin glycan structures. For example, the relative abundance of the bacterium Parabacteroides distasonis positively correlated with glycan structures containing one terminal fucose and correlated negatively with glycans containing two terminal fucose residues or with both an N-acetylneuraminic acid and a sulfate residue. This is the first comprehensive report of the impact of dietary fiber on the colonic mucin O-glycosylation and associations of these mucosal glycans with specific gut bacteria.

Reduction of cat voluntary feed intake in the short-term response to the sugar cane fibre supplementation

Obesity is a well-known syndrome of excessive body fat in cats (Felis catus) that affects the health, welfare and lifespan of animals. Consequently, different diet strategies aiming to reduce voluntary feed intake in cats have been studied. One of these consists in reducing energy intake based on reduction of feed intake. Several clinical studies have demonstrated that dietary fibre inclusion in food reduced efficiently voluntary feed intake (VFI) in dogs. However, little clinical data is available regarding the impact of dietary fibre inclusion on cat’s feeding behaviours and VFI. The aim of the current study was to test the performance of sugar cane fibre included at three different levels in extruded feline diets. The main purpose was to measure the impact of fibre inclusion on the cats’ VFI, while maintaining palatability. Four feline diets were formulated with different inclusion levels of sugar cane fibre expressed on an as fed basis (0% sugar cane fibre (control), 3.7% of sugar cane fibre (SF3.7), 5.5% of sugar cane fibre (SF5.5) and 7.3% sugar cane fibre (SF7.3)). The VFI and palatability were evaluated in two different methods: a new method using 79 cats, called ‘consumption kinetics’ based on the dynamic measure of cat’s daily consumptions in ad libitum conditions providing information about cat’s feeding pattern, and the standard palatability two-bowl (versus) test using more than 30 cats. All foods had identical palatability performance, regardless of sugar cane fibre inclusion level, while the VFI of products containing 5.5% and 7.3% sugar cane fibre decreased significantly compared to the control diet. The level of supplementation of sugar cane fibre was efficient to reduce felines VFI without impairing food palatability level, and may be a useful ingredient to add to feline diets to improve the success of the weight management programs.

Inclusion of purified dietary fiber during gestation improved the reproductive performance of sows

BackgroundThis study aimed to investigate the impacts of guar gum and cellulose as the source of dietary fiber during gestation on the reproductive performance of sows.MethodsA total of 210 sows (parities 3–6) were randomly allocated into six diets (n = 35) throughout gestation to feed graded levels of dietary fiber (DF), including a corn-soybean meal-based control diet with no wheat bran inclusion (CON, 12.5% DF), a wheat bran-rich diet (DF1, 17.4% DF), and another 4 diets (DF2, 17.7% DF; DF3, 18.1% DF; DF4, 18.4% DF; DF5, 18.8% DF) in which wheat bran were equally substituted by 1%, 2%, 3% and 4% purified FIBER MIX (guar gum and cellulose, 1:4). All sows received similar DE and other nutrients throughout gestation.ResultsDF treatment during gestation resulted in normal fecal score (1 to 5 with 1 = dry and 5 = watery) in sows compared with those received the CON diet (P < 0.05). The number of total born piglets had a tendency to be affected by dietary treatment (P = 0.07), and correlation analysis revealed a linear response of total born to dietary fiber levels during gestation (P < 0.01). Sows received the DF2, DF3, and DF5 diets during gestation had a greater ADFI during lactation compared with those in the CON group (P < 0.05) without affecting the daily body weight gain of suckling piglets. Gut microbiota compositions were dramatically changed by the gestation stage and some of those were changed by DF inclusion. Fecal acetate, propionate, and butyrate of sows were markedly increased in late gestation, and butyrate contents in feces of gestating sows were significantly affected by DF levels (P < 0.01). Serum concentrations of pro-inflammatory TNF-α were decreased and anti-inflammatory IL-10 was increased on day 30 of gestation by DF levels (P < 0.05).ConclusionsIn summary, increasing dietary fiber levels by guar gum and cellulose during gestation improved the reproductive performance of sows, which might be related to changes in immunity and gut microbiota of sows.

Conclusões: A inserção de fibra na dieta, proveniente da casca e talo da banana, bem como da mistura de ambos, mostrou efetividade de uso sobre o perfil lipídico e capacidade de manutenção dos níveis de glicemia dos ratos alimentados com dietas contendo fibra oriunda da casca e do talo.DOI: 10.12957/demetra.2018.29559 DOI: 10.12957/demetra.2018.29559

Physicochemical and sensory properties of low fat fibre enriched ice cream

Ice cream is a very favourite dairy product among all sections of the people because of its palatable nature and nutritious nature. The use of new ingredients fat replacement is a new concept and is finding wide application in the food industry recently. In this regard, a study was carried out to prepare low fat fibre enriched ice cream by incorporating inulin and fructo-oligosaccharides. Different treatments of fibre enriched ice cream prepared by incorporating inulin or fructo-oligosaccharides at 0, 3, 5 and 7 per cent levels. The mean values of pH and titratable acidity of control and treatment ice cream after preparation and during the 5 weeks storage period at -230 C showed no significant difference. However, a highly significant (P < 0.01) difference was noticed in specific gravity, viscosity, melt down and over run values between different ice cream with a proportional increase to the increase in percent of inulin and fructo-oligosaccharides. Among the different ice cream prepared, the low fat fibre enriched ice cream with 3% inulin and low fat ice cream with 3% fructo-oligosaccharides recorded the highest scores for appearance, sweetness, flavor and overall acceptability, comparable to that of control. Dietary fibre inclusion at 7% level in the ice cream recorded higher viscosity, specific graity, meltdown and over run in comparison with the low fat control ice cream.

Determination of the Intervention Strategies for the Prevention of Fetal Macrosomia Dependent Cesarean Sections in Nigeria

Background: Subsequent to the rising cesarean section rates worldwide over the past three decades, this study was done to determine the risk factors that predispose to fetal macrosomia with the aim of determining the intervention strategies for preventing fetal macrosomia dependent cesarean sections in Nigeria. Subjects and Methods: A record review of the birth weights of 2410 babies delivered in St Philomena’s Hospital, a survey of the nutritional habits of 75 mothers of macrosomic babies attending postnatal clinic within the study period, and an assessment of the level of awareness’ of the fasting blood glucose status of 75 mothers of macrosomic babies and 330 pregnant women with interviewer administered questionnaire were done. Results: The prevalence rate for fetal macrosomia in St Philomena’s Hospital was 8.4% during the study period. Cesarean section rate among women with fetal macrosomia was 39.2% compared to a rate of 18% in women who gave birth to babies with normal birth weight. It was also found that most pregnant women and mothers of macrosomic babies were not aware of their fasting blood glucose status. Majority of mothers of macrosomic babies preferred high glycemic index diets and also consumed sugary beverages on daily basis. Conclusion: Fetal macrosomia is a preventable outcome of pregnancy in the presence of moderate dietary restriction, low glycemic index diets as well as the inclusion of dietary fiber in the diet of pregnant women. Furthermore, a lower incidence of fetal macrosomia is capable of reducing cesarean section rates in Nigeria.

UTILIZATION OF POTATO PEELS AS A FIBER SOURCE IN FEEDING TWO LINES OF GROWING RABBIT

Total numbers of 300 growing V. and Alex. rabbits at age of 4-weeks were used to study the effect of dietary potato peels as a partial replacement at levels 5, 10, 15 and 20% of dietary fiber inclusion. Rabbits of each line were randomly classified into five equal groups (30 each). The 1th group received the basal diet and served as control diet. The other four groups received the basal diet with replacement potato peels meal at the studied levels, respectively. The chemical composition of the potato peels meal clearly shows that it contains 14% crude protein, 15.6% crude fiber and 57.1% nitrogen free extract and these compounds falls within ranges of studied wheat brain and Alfalfa hay. While, ether extract and ash content of potato peels meal were higher than those of other studied materials. Significant difference was recorded for body weight, gain, feed intake and feed conversion as a result of lines difference over all the experimental growth period (4-10) week old. In that, average body weight of Alex. rabbits and its gain were higher than those of V. line. The opposite was true with feed intake, where rabbits of V. line consumed more diet compared with those of Alex. line. Dietary potato peels meal treatments (10%) significantly increased body weight and weight gain and consequently feed intake was also increased. Meanwhile, the best score of feed conversion was attained with Alex. rabbits fed inclusion level of 10% potato peels meal. This trend did not continue but it significantly decreased as increasing inclusion level up to 20% and resulted to impaired feed conversion which being 3. 89 for V. rabbits and followed by 3.37 for Alex. rabbits. The relative economic efficiency of the different formulated diets as affected by dietary treatments of 5 and 10% were highly by 8.9 and 16.1% over the corresponding of the control group for Alex. rabbits and followed by 7.2 and 5.5% over the control group of V. rabbits, respectively. In conclusion, potato peel meal can be used as a good alternative source of fiber at levels of 5 and 10% in growing V. and Alex. rabbits diets, respectively with a good influence on productive performance and can be considered a cheap of fiber ingredients in rabbits diets formations.

Starch digestibility index and antioxidative properties of partially baked wheat—flour bakery with an addition of dietary fibre

The aim of this study was to evaluate the impact of bake‐off technology with the freezing process of wheat‐flour rolls, and with the inclusion of dietary fibre on the starch digestibility index and antioxidative properties. Research material consisted of four kinds of wheat rolls. These were baked conventionally and with bake‐off technology, with and without the additional 10% fibre (oat fibre and inulin). The following parameters were measured: The content of the total starch (TS), slowly digestible starch (SDS), rapidly digestible starch (RDS), the starch digestion index (SDI), the content of the total polyphenols and the ability to quench the free ABTS• + radical. The freezing process and the addition of dietary fibre contributed to a significant increase of the SDS fraction, while the RDS and SDI were decreased in partially baked rolls (p &lt; 0.05). The amount of the total polyphenols was significantly higher with the addition of fibre and the use of the freezing process, while the antioxidant activity was increased when fibre was incorporated into the conventionally baked rolls (p &lt; 0.05). Freezing applied simultaneously to bake‐off technology, and the addition of oat fibre and inulin to the dough resulted in bakery products of not only reduced starch digestibility but containing more antioxidants, which from a nutritional point of view, appears to be advantageous.

Dietary fibre and crude protein: impact on gastrointestinal microbial fermentation characteristics and host response

The role of the gastrointestinal tract microbiota in animal health and nutrition has become the subject of intensive research. Carbohydrates and crude protein are major components of swine diets and numerous studies have been performed looking at the effect of inclusion of dietary fibre with possible functional properties. In recent years, our understanding of the diversity and functionality of the gastrointestinal tract microbiota has increased further enabling the possibility for their targeted modulation. However, favouring potential beneficial bacteria, inhibiting possible pathogens or promotion of the formation of desired metabolites, is complex and underlies many factors and uncertainties. Approaches targeting this complex ecosystem (and discussed in this review) include the utilisation of fermentable carbohydrates such as resistant starch, cereal 1–3/1–4 β-glucans, arabinoxylans, inulin or other sources from legumes and industrial by-products. In addition, strategies regarding protein level and the protein : carbohydrate ratio are discussed briefly. Results are both promising and sometimes rather disillusioning considering the dietary concentrations needed to show biologically relevant effects. Deriving recommendations for an optimal inclusion rate of dietary fibre for weaning, growing pigs and sows and maximum levels for dietary crude protein may be one of the main challenges in the near future in the swine industry.

Effects of different amounts of konjac flour inclusion in gestation diets on physio-chemical properties of diets, postprandial satiety in pregnant sows, lactation feed intake of sows and piglet performance

This study was conducted to investigate the effects of different amounts of konjac flour (KF) inclusion in the gestation diet on the physio-chemical properties of diets, postprandial satiety in pregnant sows, lactation feed intake of sows and piglet performance during two successive reproductive cycles. Multiparous Landrace sows (n=140) were assigned randomly to one of four experimental diets, and four gestation diets were formulated to contain varying amounts of KF at 0%, 0.6%, 1.2% or 2.2%, respectively. The water binding capacity (WBC) (P<0.01), swelling capacity (P<0.01) of gestation diets, the concentration of total short chain fatty acids (P<0.05) after in vitro fermentation of gestation diets increased linearly with increasing inclusion amounts of KF. During the second reproductive cycle, increasing dietary KF linearly increased plasma concentrations of short chain fatty acids (SCFA) 4h postprandial (P<0.05) and glucagon-like peptide (GLP-1) 2h postprandial (P<0.05), but decreased the plasma concentration of cortisol (linearly, P<0.05) 1h postprandial. In addition, there was a linear decrease of the non-feeding oral behavior of gestating sows (P<0.01) when dietary KF increased. There were linear increases in lactation feed intake of sows during entire lactation period (P<0.01) with increasing amounts of KF in the gestation diet. In addition, the number of piglets weaned (linearly, P<0.01; quadratic, P=0.01), average piglet weights and litter weights on day 21 of lactation (linearly, P<0.01) increased with increasing inclusion amounts of KF. In conclusion, inclusion of dietary fiber with great WBC, swelling capacity and fermentation capacity in the gestation diet was beneficial for enhancing postprandial satiety in pregnant sows, increasing lactation feed intake and improved number of piglets weaned per litter through greater pre-weaning survival.
