Use Of Sugar Beet Pulp Research Articles

Effect of zearalenone in sugar beet products on zootechnical and reproductive performance and lesions of sows and piglets.

Following the use of sugar beet pulp that was retrospectively found to be predominantly contaminated with zearalenone (ZEN) in diets of reproducing sows largely exceeding the EU-guidance value for critical ZEN concentration of 0.25mg/kg, farmers did not report any changes in the reproductive performance of sows. Thus, the aim of the study was to verify this guidance value in a dose-response setup by using sugar beet pulp as a ZEN source hitherto not considered a risky feedstuff additionally characterized by comparatively low levels of deoxynivalenol. A total of 90 sows was equally allocated to one of the three feed groups during experimental lactation 1 and up to 40days after insemination: CON with a minimal ZEN concentration, ZEN1 with a target concentration of 250µg ZEN/kg feed, and ZEN2 with a target concentration of 500µg ZEN/kg feed. Thereafter, all sows received the same feed without ZEN for the rest of gestation, and the following lactation for testing of putative carry-over effects resulting from previous ZEN exposure. Exposure of sows to ZEN with blood serum as an indicator was linearly related to dietary ZEN concentrations. Reproductive and zootechnical performances of sows were only affected by ZEN exposure at weaning weight. Clinical-chemical parameters indicated no clear effect of ZEN exposure. An influence of ZEN on the occurrence of tail and ear injuries (not necrosis) in piglets and lesions on the mammary complexes in sows is possible. The influence of a ZEN concentration above the EU guidance value on the study farm can therefore not be neglected.

Sugar Beet Pulp as a Biorefinery Substrate for Designing Feed.

An example of the implementation of the principles of the circular economy is the use of sugar beet pulp as animal feed. Here, we investigate the possible use of yeast strains to enrich waste biomass in single-cell protein (SCP). The strains were evaluated for yeast growth (pour plate method), protein increment (Kjeldahl method), assimilation of free amino nitrogen (FAN), and reduction of crude fiber content. All the tested strains were able to grow on hydrolyzed sugar beet pulp-based medium. The greatest increases in protein content were observed for Candida utilis LOCK0021 and Saccharomyces cerevisiae Ethanol Red (ΔN = 2.33%) on fresh sugar beet pulp, and for Scheffersomyces stipitis NCYC1541 (ΔN = 3.04%) on dried sugar beet pulp. All the strains assimilated FAN from the culture medium. The largest reductions in the crude fiber content of the biomass were recorded for Saccharomyces cerevisiae Ethanol Red (Δ = 10.89%) on fresh sugar beet pulp and Candida utilis LOCK0021 (Δ = 15.05%) on dried sugar beet pulp. The results show that sugar beet pulp provides an excellent matrix for SCP and feed production.

The Use Of Agricultural Waste In Solving Of Environmental Problems In Democratic Republic Of The Congo

The presence of chromium in wastewaters produced from mining industries in Democratic Republic of the Congo is harmful for the environment. As a promising and polishing method for heavy metals removal from wastewaters, adsorption has been used with agricultural waste as low adsorbent. In this study, the use of sugar beet pulp has been investigated for the removal of hexavalent chromium from aqueous in batch adsorption mode. Adsorption experiments were conducted to obtain the optimal conditions combinations for the highest percent removal. Four parameters were studied such as contact time (30–180min), initial chromium concentration (10-50mg/L), pH (2-9) and solid to liquid ratio (0.25 g/100 mL-3 g/100 mL). However, the agitation rate was equal to 100 rpm and the room temperature was considered. The highest percent removals of 90.53% for 10 ppm concentration and 76.34% for 50 ppm concentration were achieved at the following conditions: pH 2, contact time 90 min, S/L ratios of 2 g/100 mL and 3 g/100 mL respectively. Langmuir and Freundlich adsorption isotherms were used for the mathematical description of adsorption equilibrium. Freundlich isotherm fitted well the equilibrium data. The maximum capacity (Qmax) from the Langmuir isotherm was found to be 11.299 mg/g. These results indicated that sugar beet pulp can be used as low cost adsorbent for the removal of chromium from mining industries wastewater to avoid environmental problems

Improvement of feed intake, digestibility, plasma metabolites, and lactation performance of dairy cows fed mixed silage of sugar beet pulp and rice straw inoculated with lactic acid bacteria

A study was conducted to investigate the inclusion effects of sugar beet pulp and rice straw mixture silage with inoculation (BRMS), in place of whole-plant corn silage (CS), on the dry matter intake, total-tract nutrient digestibility, plasma metabolites, rumen fermentation, and lactation performance in high-production dairy cows. Sixteen multiparous Holstein cows (body weight, 622 ± 35 kg; days in milk, 90 ± 11 d; mean ± standard deviation) were used in our experiments; the experiments were based on a repeated 4 × 4 Latin square design for 21 d, and each experimental period consisted of 14 d of adaptation, followed by 7 d of data collection. The 4 dietary treatments used were (dry matter basis): (1) 0% BRMS and 28.6% CS (0BRMS); (2) 4.3% BRMS and 24.3% CS (15BRMS); (3) 8.60% BRMS and 20.0% CS (30BRMS); and (4) 12.9% BRMS and 15.7% CS (45BRMS). The increasing inclusion of dietary BRMS was observed to linearly increase the total volatile fatty acids and the propionate concentration. The dry matter intake and digestibility values of neutral detergent fiber and acid detergent fiber increased linearly as the percentage of BRMS increased up to 45%. Milk yield linearly increased with the increase in the content of BRMS (39.0, 39.8, 40.9, and 40.3 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). The increasing inclusion of dietary BRMS induced a decrease in the ammonia nitrogen and milk urea nitrogen concentration, leading to a linear increase in milk protein production (1.15, 1.26, 1.35, and 1.27 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). In conclusion, the diets with the replacement of CS with BRMS up to 45% were beneficial to the production performance of high-production dairy cows, indicating that this method may be an appropriate use of sugar beet pulp and rice straw.

Influence of the incorporation mode of sugar beet pulp in the finishing diet on the digestive tract and performances of geese reared for foie gras production

The aim of this work was to study the effects of incorporating sugar beet pulp (SBP) into the diet of geese in two feeding systems (complete pelleted feed or loose-mix feeding system) on crop development and performance. A total of 480 1-d-old male geese were divided into three groups whose diet differed from d 56 to 90: a complete pelleted diet containing 50% corn (control diet: AMEn 11.5 MJ/kg; CP 161 g/kg), and no SBP; a complete pelleted diet containing 50% corn and 10% SBP (SBPcp diet: AMEn: 11.5 MJ/kg; CP: 161 g/kg); and a mix in the same feeder (SBPlm diet) of 500 g/kg of protein-rich pellets containing 20% SBP (SBPprp: AMEn: 9.0 MJ/kg; CP: 250 g/kg) and 500 g/kg of whole corn (WC: AMEn: 14.0 MJ/kg; CP: 72 g/kg). Body traits, including crop volume, were measured at d 91. From d 91 to 106, 88 birds/group were overfed with a mixture containing mainly corn and water before slaughter to measure fatty liver performance. Feed intake from d 56 to 90 was higher (+10%; P = 0.004) in the SBPcp group than the other two, but at d 90, the body weight (BW) of the birds was higher (+7%; P = 0.002) in the SBPlm group than the other two. At d 91, the volume of the crop was greater in the SBPcp group (80.4 mL/kg of BW, P < 0.001) than in the control group (60.3 mL/kg of BW), the SBPlm group being intermediate (64.1 mL/kg of BW). Feed intake (13,321 g), weight gain (2,733 g), and feed-to-gain ratio (4.9) during the overfeeding period, as well as fatty liver weight (963 g) and commercial grading, were similar (P > 0.05) between the three groups. In conclusion, the use of sugar beet pulp in the diet of finishing geese helps the adaptation of the digestive tract to the overfeeding period, even in a loose-mix feeding system based on whole corn.

Sugar beet pulp as biomass

The sugar beet industry produces considerable amounts of organic waste and by-products. Sugar beet pulp (SBP) is the residue that remains after sugar extraction. SBP is a lignocellulosic by-product of the sugar industry and generally used as animal feed at relatively low price. Instead of cattle feeding, SBP can be used as a raw material for industrial applications because it is low-cost and available in large amounts. Biomass is a clean and renewable energy source. The use of SBP for the production of ethanol, methanol, single cell protein, biofuels etc. is economically very attractive. This literature review evaluates the use of SBP as biomass.

A meta-analysis on the role of soluble fibre in diets for growing rabbits

In this review, the methods used to measure fibre and soluble fibre fractions are briefly presented and the effects of the soluble fibre content in diets for growing rabbits reviewed by a meta-analysis of studies available in literature, with the aim of elucidating the relationships with other dietary nutrients. Soluble fibre was assumed as the difference between total dietary fibre (TDF) and neutral detergent fibre (NDF), as it is simple to obtain and has been measured in numerous studies. Dietary soluble fibre content affects the digestive utilisation of soluble and insoluble fibre fractions and its increase is associated with reduced mortality in growing rabbits affected by epizootic rabbit enteropathy. This effect could be attributed to the high fermentability of soluble fibre, the consequent changes in the intestinal microbiota and an enhanced gut barrier function just after weaning. A supply of 12-14% of soluble fibre (as-fed) is recommended in diets for post-weaning and growing rabbits containing around 30% NDF and 18% acid detergent fibre. The positive effects of increasing dietary soluble fibre are linked to the use of sugar beet pulp as primary source of soluble fibre and should be confirmed with other sources of soluble fibre.

Methylene blue (cationic dye) adsorption onto sugar beet pulp: Equilibrium isotherm and kinetic studies

Sugar beet pulp (SBP) is a well known adsorbent, however the use of sugar beet pulp as an adsorbent for removal of cationic dyes was not reported in the literature, so far. Batch adsorption experiments were conducted to study the effects of contact time, initial concentration (20–50 mg/L) and pH (2–8) on the removal of methylene blue (MB) from aqueous solution by SBP. Freundlich and Langmuir isotherm models were found to be suitable for description of MB adsorption on SBP. The SBP was found to have a Langmuir monolayers adsorption capacity of 714.29 mg/g at pH 8 and 25 °C. The results showed that the pseudo-second-order kinetic model best described the absorption process ( R 2 ≥ 0.9999). The extent of MB adsorption on SBP increased along with an increase of initial pH of the solution and initial MB concentration. The results demonstrated that the SBP is a promising adsorbent for removal of MB from aqueous solutions.

Effets de l'incorporation de pulpe de betterave dans les aliments du porcelet et du porc en croissance : performances de croissance, digestibilité et composition corporelle

Summary — Consequences of the inclusion of sugar beet pulp in diets for early weaned and growing pigs. The effect of extrusion of wheat and of the inclusion of 6% of sugar beet pulp in a pelleted starter on the performance of the weaned piglet has been studied in two experiments. In the first experiment, 80 crossbred castrated male and female piglets weaned at 21 days of age raised individually y were used in a 2 x 2 factorial arrangement to compare their performance between weaning and 25 kg g live weight. Average feed intake was similar between treatments, but extrusion of wheat had no significant effect on growth performance and feed conversion ratio. The association of normal wheat with sugar beet pulp improved significantly growth rate (P < 0.02) and feed conversion ratio (P < 0.06), in particular during the period following immediatly weaning, ie, 193 vs 156 g/day and 193 vs 2.32, respectively. In the second experiment, 32 crossbred castrated piglets were used to evaluate faecal, then ileal digestibilities of dietary components. Extrusion did not improve digestibility. Ileal digestibility but not faecal digestibility of dry matter and energy was reduced (P < 0.001 ) by the inclusion of sugar beet pulp in the diet. Post-ileal digestibility of all dietary components was higher in animals fed fibrous diet. During the growing-finishing period between 25 and 100 kg live weight, the inclusion of a similar level of 6% of sugar beet pulp in a normal wheat based diet was tested. Piglets of the first experiment were randomly affected to one of the two diets taking into account their previous diet, sex and weight. The average daily gain for the whole period was slighly but not significantly reduced and feed conversion ratio was unchanged in animals receiving sugar beet pulp. However, feed conversion ratio expressed as digeatible energy per kg of body weight gain was reduced in animals receiving beet pulp in their diet. At slaughter, the percentage of lean meat was improved from 52.8 to 54.0% (P < 0.05) as a consequence of a linear decrease in the backfat thickness (P < 0.05) of carcasses of animals receiving sugar beet pulp. No difference in the weight of lean cuts was observed but the use of sugar beet pulp decreased significantly the weight of fat cuts (P < 0.01 It was suggested that for a similar nitrogen retention a reduction in the digestible energy intake reduces the deposition of fatty tissues but the total amount of lean meat in the carcass was not affected by the inclusion of sugar beet in the diet.

Risk Factors for Clinical Mastitis in Herds with a Low Bulk Milk Somatic Cell Count. 1. Data and Risk Factors for All Cases

The incidence rate of clinical mastitis in 125 herds with a low annual bulk milk SCC (<150,000 cells/ml) was modeled using a Poisson regression model. The rate of clinical mastitis was significantly associated with some variables that increased the exposure to environmental microorganisms: poor cubicle cleanliness increased the mastitis rate; rubber mats in cubicles were associated with a higher incidence; and drinking water from sources other than public water also increased the rate of mastitis. Other variables may be associated with host resistance: an increasing percentage of cows leaking milk increased the rate of mastitis; postmilking teat disinfection was associated with a higher incidence of clinical mastitis; and a high frequency of cubicle disinfection was also associated with more mastitis. Three other variables were associated with the rate of mastitis: breed (Holstein-Friesian had a lower incidence than the Meuse-Rhine-Yssel breed); use of sugar beet pulp in the ration increased the mastitis rate; and in herds with high milk production a higher incidence of mastitis was observed. These items are discussed in respect to their causal relation to clinical mastitis.

Effects of feeding silage and sugar beet pulp, separately, mixed or in an ensiled blend, upon milk production in british friesian dairy cows

There is increasing interest in the addition of dry feed materials to grass at ensiling, primarily as a means of reducing effluent production, although other benefits claimed include improvements in silage fermentation and animal performance.A large number of studies have demonstrated lower effluent outputs and improvements in silage fermentation due to the inclusion of materials such as cereals and sugar beet pulp, although experiments examining the effects on animal performance are limited.Recently, Jones and Jones (1988) observed higher liveweight gains from beef steers fed silage produced by ensiling grass with molassed beet feed compared to animals fed the same quantity of beet feed mixed with silage produced from untreated grass at the point of feeding. The major objectives of the present study were to evaluate the possible use of sugar beet pulp as an absorbent material in silage making and to examine the effects of its inclusion with grass at ensiling on animal performance.
