Effects of Different Protein Sources on Growth Performance, Muscle Flavor Substances and Quality Structure in Triploid Crucian Carp

A 56-day feeding trial was conducted to evaluate the effect of different dietary protein sources on the growth performance, muscle flavor substances, and quality structure of Triploid Crucian Carp. Three isonitrogenous (32.00%), isolipidic (8.00%), and isoenergetic (18.00 MJ kg−1) practical diets were formulated. These diets consisted of fishmeal as the animal-derived protein source (AP), a combination of soybean meal and rapeseed meal as the plant-derived protein source (PP), and a mixture of fishmeal, soybean meal, and rapeseed meal as the mixed protein source (MP). Each diet was randomly assigned to triplicate tanks of fish and each tank was stocked with 25 fish (11.5 ± 0.4 g). The fish were fed until apparent satiation twice a day. The results showed a significant enhancement in the growth performance of Triploid Crucian Carp in the AP group compared with both the MP and PP groups (p < 0.05). Dietary plant derived protein can remarkably reduce the crude lipid content and increase the moisture content of the whole body and the dorsal muscle (p < 0.05). The antioxidant ability of fish in the PP group and MP group was better than that in the AP group (p < 0.05). Regarding free amino acids composition of muscle, the contents of glycine, methionine, and lysine were significantly enhanced in the AP group, while the histidine content was significantly increased in the PP group (p < 0.05). In terms of texture, dietary plant protein significantly improved the muscular hardness, gumminess, and chewiness. The activities of intestinal trypsin and alkaline phosphatase (ALP) of fish in the PP group were significantly higher than that in the AP group (p < 0.05). The expression levels of hepatopancreas TOR and IGF1 genes in the PP group were significantly higher than that in the MP group (p < 0.05). The present results indicate dietary fishmeal significantly improved the growth performance and muscular flavor glycine content, while dietary plant-based protein increased crude protein content, antioxidant ability, and muscular texture performance of Triploid Crucian Carp.

Effect of different protein sources on protease activity of Neon tetra, Paracheirodon innesi (Myers, 1936) juveniles

Neon tetra, Paracheirodon innesi, akvaryum sektörü açısından oldukça yüksek değere sahip bir balık türüdür. Bu çalışmada, farklı protein kaynaklarının (soya protein konsantresi, soya unu, balık unu, karides unu, krill unu, mısır glüteni, ve tavuk unu) erken dönem proteaz enzimleri üzerine inhibe edici etkilerini bulmak amacıyla invitro analizler yapılmıştır. Çalışma sonunda, en yüksek inhibisyon oranı bitkisel protein kaynaklarından soya protein konsantresinden (%53,59±0,58) elde edilmiştir. Diğer yandan, en düşük inhibisyon oranları karides ve tavuk unundan elde edilmiştir (sırasıyla, %21,88±0,74 ve %21,88±1,26) (p>0,05). Sonuç olarak, bu türün erken dönem beslenmesinde karma yemlerinde soya protein konsanteresinin protein kaynağı olarak kullanılmaması gerektiği kanaati doğmuştur.

Similar effects of milk protein and blends of milk and plant-based protein on appetite-related hormones in 7- to 8-year-old healthy Danish children: secondary analyses from the PROGRO randomised trial.

The effect of different protein sources on the appetite-related hormones in children is largely unknown. We investigated the effect of milk protein versus blends of milk and rapeseed protein on plasma leptin and adiponectin in children. We included 88Danish 7- to 8-year-old children randomised to receive 35g protein/day for 4weeks in 2018 as either milk protein or blends of milk and rapeseed protein (ratio 54:46 or 30:70). Outcomes included absolute and fat mass-adjusted adiponectin and leptin measured at baseline, Weeks 1 and 4. There was no difference in changes in absolute and fat mass-adjusted adiponectin and leptin after 1 or 4weeks between the three groups (p≥0.100). Leptin increased within all groups (p≤0.046). Combining the three groups, leptin and fat mass-adjusted leptin increased by 23% (95% CI 11;35) and 17% (6.4;29) during the intervention respectively (both p≤0.001). Adiponectin variables did not change during the intervention period. There were no differences between milk protein and blends of milk and rapeseed protein on absolute and fat mass-adjusted leptin and adiponectin in healthy children with a habitual intake of milk. However, leptin increased within all three groups. Future studies should further investigate effect on appetite-related hormones of rapeseed protein alone.

Effect of Different Protein Sources with Different Levels on Growth Performance and Carcass Dissection of Japanese Quail (Coturnix Coturnix Japonica)


 The fish meal and soybean meal are the most used protein sources in poultry rations, especially in quail birds due to their higher requirements of crude protein that affecting their growth rate. The objective was to investigate the effect of source of dietary protein and its levels on growth traits, carcass characteristics and some blood parameters. This study was conducted at poultry farm in Duhok city/College of agricultural engineering sciences/Animal production Department/ Kurdistan Region- Iraq, 2020. A total of 360 one-day unsexed chicks of J. quail (Coturnix Coturnix Japonica) were divided equally into two groups (treatments) according to protein source (fishmeal and soybean meal groups), each group involved three levels of crude protein (20, 23 and 26 % CP), and each level had three replicates. The birds distributed randomly on the cages which contained 20 birds / replicate. The main results were as follow; fishmeal source of diet protein surpassed significantly soybean in live body weight (LBW), weight gain (WG), feed conversion ratio (FCR) and carcass characteristics. The level of 26 % crude protein (CP) in the diet recorded the best LBW, WG and FCR; while the level of 23 % CP surpassed both 20 % and 26 % in mortality rate and carcass dissections. However, total protein, hemoglobin and albumen parameters in the blood were not affected significantly (p>0.05) neither by protein source nor by its levels in the quail rations. As conclusion, fish meal was better than soybean meal; and 26 % CP was the best level.

Performance of broiler chickens fed different animal protein sources as replacement for fish meal

Searching for least cost feed component should be extended to unconventional feedstuffs that are locally available and cheaper to come by. Therefore, an eight-week experiment was carried out to determine the effect of different protein sources (maggot, termite, grasshopper and lizard meal) on performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks of Marshall Breed were used for the experiment. An eight-weekstudy was conducted to evaluate the performance of broiler chickens fed the four different sources of animal protein. Diet I contained 5% fish meal while Diets 2, 3, 4 and 5 contained 5% maggot meal, termite meal, grasshopper meal and lizard meal, respectively at the starter phase. The finisher phase contained 2.5kg each of the protein sources respectively. The chicks were allotted to five dietary treatments each replicated thrice with ten birds perreplicate in a completely randomized design (CRD). Proximate composition of the test ingredients showed that lizard meal had the highest (55.66%) crude protein and crude fibre (5.53%). Termite meal exhibited highest (26.46%) ether extract followed by maggot meal (9.79%) with the lowest (4.02%) from lizard meal. The feed intake value (4700.16g) in birds fed diet 1 was significantly (P<0.05) higher than others. Birds fed Diet 2 showed significant (P< 0.05) better final weight gain (2367g) than those fed other test ingredients. Birds fed diet 2 (maggot meal) performed better than others in absolute weight gain (2287g) which is very close to those fed fish meal (Diet 1). In conclusion, maggot meal in this study enhanced performance and is thus recommended as a replacement for fish meal.

Use of soy as a source of protein in low-fat yogurt production: microbiological, functional and rheological properties

The objective of this study was to evaluate the effect of different protein sources incorporated into milk to produce low-fat yogurt (LF-yogurt). Five treatments were used: YC – yogurt control (without protein supplementation), YM – yogurt with milk powder, YWP – yogurt with whey protein, YSP – yogurt with soy protein, and YSF – yogurt with soy flour. Microbiological counts of Streptococcus thermophilus and Lactobacillus bulgaricus, pH, lactic acid and changes in rheological and structural properties (firmness, color, microstructure and syneresis) were followed throughout 28 days of storage. Antioxidant capacity (DPPH and ABTS assay) and total phenolic compounds were also analyzed. Addition of different ingredients influenced S. thermophilus and L. bulgaricus CFU counts. LF-yogurts supplemented with milk powder, soy flour and soy protein were firmest, and yogurts supplemented with milk powder and soy flour had the least syneresis. LF-yogurts with soy flour were darker, redder and yellower, contained more polyphenols and exhibited higher antioxidant activity. Thus, supplementation of LF-yogurt with soy is interesting since it confers functional activity to the yogurt and also modify its technological properties.

Supplementation of lamb ewes with different protein sources in deferred marandu palisadegrass (Brachiaria brizantha cv. marandu) pasture

ABSTRACT The objective of this study was to evaluate the effect of different protein sources on the performance of lamb ewes and their offspring supplemented in deferred pasture. The treatments were the different protein sources: soybean meal, cotton cake, babassu cake and coconut cake. The ewes were weighed and evaluated for their body condition score during the gestation, parturition and weaning phases. The lambs were weighed at birth and at weaning. The structural variables and chemical composition of the pasture were evaluated during the usage period. Grass height and forage mass were higher when the ewes were in the gestation and weaning stages. The leaf mass was not altered during the pasture usage with a mean value of 566.1kg ha-1 DM. The highest levels of crude protein in the leaf blade were observed during the parturition and weaning phases. The body weight of the ewes did not differ between the sources with averages 45.0, 39.9 and 36.6kg for the gestation, parturition and weaning phases, respectively. Weights at birth and at weaning had an effect from protein sources, with the highest values observed in the lambs of ewes who received soybean meal and babassu cake supplementation. The lambs of ewes supplemented with soybean had higher average daily gain and total gain. Babassu, coconut and cotton cakes can replace soybean meal in supplementation of ewes in deferred pasture.

The aim of the study is to determine the inhibitory effect of different protein sources on protease activity of Northern pike, E. Lucius, during larval ontogeny. For this purpose, Northern pike were fed from yolk sac absorption until 21 days after hatching (DAH). At that point, larvae were sampled on 7, 14 and 21 DAH days and the activity of enzyme was analyzed in vitro. In the study, two different fish meal, chicken meal, krill meal, corn gluten, soybean protein concentrate, soybean meal and dried distillers grains with solubles were tested. Fish meal-I showed the lowest effect (7.53 %) on 7 DAH larvae. Moreover, chicken meal has the highest inhibitory effect on the proteases in the first week (68.27%). In the following period (DAH 14), although the inhibition ratio dramatically increased in all ingredients, fish meal-I has still the lowest effect on proteolytic activity (55.66%). In the same period, the highest effect was obtained from krill (82.28 %) and chicken meals (86.73 %), respectively. Then, there was no statistical difference between fish meal-I, fish meal-II and corn gluten in the 21 DAH and relatively lower than the others (p>0.05). Additionally, chicken meal again has the highest effect on juveniles with the ratio 89.27 %. As a result, the increase of proteolytic activity was notably increased in 7-14-21 DAH, however, it is concluded that feeding larvae and juveniles with live prey is still suggested to get better result for such a carnivorous species culture.

73 Effects of vegetable and animal protein sources and nutrient specifications on the nursery pig gut microbiome

Abstract The objective of the study was to investigate the effect of different protein sources and nutrient specification levels on the gut microbiome composition of nursery pigs. A total of 120 crossbred gilts (Large White ′ Landrace ′ Duroc, initial BW 6.74 ± 0.06 kg, 18 days of age) were allotted to 1 of 6 treatments: animal protein source with nursery diet specifications (AN); animal protein source with grower diet specifications (AG); plant protein source with nursery specifications (PN); plant protein source with grower diet specifications (PG); plant protein source, nursery diet specifications, and an enzyme + essential oil cocktail (PN+EOE), and plant protein source, grower diet specifications, and an enzyme + essential oil cocktail (PG+EOE). There were 4 pigs per replicate and 5 replications per treatment, in a randomized block design. On d 43, 1 pig per replicate was sacrificed, and cecum and colon digesta samples were collected for gut microbiome analysis and profiled though MiSeq 16S rRNA sequencing. Data were analyzed using univariate and multivariate methods within R. No differences in alpha or beta diversity were detected based on protein source, nursery diet specification, or inclusion of EOE; however, a number of discriminating taxa were present between pigs fed treatments with different protein sources. For instance, abundance of Parabacteroides was increased in colonic PG samples (P = 0.01) compared with AG, and abundance of Lachnospiraceae was increased in all samples of AG compared with PG (P = 0.009). Eubacterium (P = 0.044) and Turicibacter (P = 0.031) were both more abundant in colonic AN samples when compared with PN samples. In conclusion, the gut microbial communities, at large, in the cecum or colon, were not significantly modified by the presence of different protein sources in nursery diets.

Effects of protein quantity and type on diet induced thermogenesis in overweight adults: A randomized controlled trial

Protein content of a meal is hypothesized to drive DIT dose-dependently. However, no single meal study exists comparing two different doses of protein on DIT. In addition, the source of protein, particularly whey protein, was shown to have a higher DIT than casein and soy in the acute setting, however the mechanism behind this difference is not yet clear. The aim of the present work is therefore to evaluate the efficacy of two different doses and types of protein (whey protein and casein) on DIT in overweight adults. Randomized, double blind crossover including seventeen overweight men and women assigned to four isocaloric study treatments where protein and carbohydrate were exchanged: control, 30g of whey protein microgels (WPM30), 50g WPM (WPM50) or 50g micellar casein (MC50). Energy expenditure was measured by indirect calorimetry. Blood, breath and urine samples were collected in order to measure substrate oxidation, amino acid profile, glucose and insulin, protein turnover and other metabolic parameters. DIT was 6.7±3.7%, 13.0±5.0%, 18.0±5.0% and 16.0±5.0% for control, WPM30, WPM50 and MC50, respectively. There was a significant difference between WPM50 and WPM30 (p<0.005) and a trend was observed between WPM50 and MC50 (p=0.06). WPM50 resulted in the highest total, essential, and branched-chain plasma amino acid concentrations when compared with the other study treatments (p<0.005) and a higher insulin concentration than MC50 (p<0.005). Protein oxidation was higher for WPM50 than MC50. Protein turnover was significantly correlated with DIT through total leucine oxidation (r=0.52, p=0.005). Our findings show that DIT does increase at a dose beyond 30g of WPM and that the type of dairy protein may have an effect on DIT with WPM tending towards a higher DIT than casein. Although further research is required to understand the mechanism behind the effect of different protein sources on thermogenesis, we suggest that amongst the components of protein turnover, protein oxidation maybe an important driver of thermogenesis at doses higher than 30g. These results have concrete implications when choosing a dose of protein to optimize its thermogenic effect. NCT02303080 www.clinicaltrials.gov.

The Utilization of Different Protein Sources as Soybean Meal Substitution in the Flushing Diet on Reproductive Performances of Doeling

This research aimed to evaluate the effect of different protein sources (plant or animal source) as substitution of 50% soybean meal protein in the flushing diet on early reproduction performances of doeling. The treatments were three types of flushing diet, i.e., Control diet containing soybean meal (C), diet containing Indigofera meal (IM), and diet containing cricket meal (CM). Diet IM and CM were substitution of 50% soybean meal protein in the ration. Completely randomized design was used with three treatments and four replications by using twelve Sapera doeling. The experiment with flushing diet was done started from three weeks before mating (including adaptation), during mating and following one month after pregnancy. Parameters measured were nutrient consumption, BCS, plasma glucose, cholesterol, progesterone hormone and reproductive performance. The results showed that treatments of utilization of different protein sources were not significantly affected the feed consumption, BCS and reproductive performances of doeling, but it had significant effect (P&lt;0.05) on plasma glucose and cholesterol. The protein source of Indigofera and cricket meal showed in improving of progesterone status to support until 30 days pregnancy. Diet containing cricket meal could improved onset estrous and duration of estrous. It was concluded that cricket meal can be used as an alternative protein source to substitute of 50% soybean meal protein in the Sapera doeling flushing diet and it can improve the reproductive performances.

The effect of dietary protein source on serum lipids: Secondary data analysis from a randomized clinical trial

Plant-based diets can lower serum lipids. Whether soy foods offer additional benefits remains controversial. To determine the effect of different protein sources on serum lipids and glucose metabolism, emphasizing comparisons between soy and nonsoy plant-based diets. Secondary data analysis. A total of 173 postmenopausal women were randomized to 1 of 4 weighed metabolic diets for 6 weeks. Diets were equivalent in energy, protein, and fat with at least 80% of protein from either nondairy animal, dairy, nonsoy plant, or soy foods. At baseline and week 6, total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, glucose, and insulin were measured. Changes in variables during the diet period were compared within and among groups using t tests and analysis of variance. TC decreased 38.8mg/dL in soy group (P<.001 vs dairy and animal) and 30.5mg/dL in nonsoy plant group (P=.003 vs dairy, .03 vs animal). LDL decreased 28.3mg/dL in soy group (P<.001 vs dairy and animal) and 20.6mg/dL in nonsoy plant group (P=.005 vs dairy, .06 vs animal). HDL decreased 12mg/dL in soy group (P=.003 vs dairy, .0008 vs animal) and 10mg/dL in nonsoy plant group (P=.05 vs dairy, .04 vs animal). There were no significant differences in lipid changes between soy and nonsoy plant-based diets. No differences among groups in changes in triglycerides, glucose, or insulin were seen. Soy and nonsoy plant-based diets reduced TC and LDL with no significant difference between them. Further studies are needed to determine the specific lipid-lowering components of both soy and nonsoy plant foods.

EFFECT OF DIFFERENT DIETARY PROTEIN SOURCES ON MORPHO-HISTOMETRY OF TESTIS AND EPIDIDYMIS, LIBIDO AND EPIDIDYMAL SPERM FUNCTION IN SHEEP

This study aimed to evaluate the effect of different protein sources, cotton seed meal (CSM), soybean (SBM) and dried distiller’s grains with soluble (DDGS) in diet of growing male lambs on morpho-histological characteristics of the testis and epididymis, characteristics of epididymal spermatozoa and serum testosterone concentration. Total of 20 growing cross breed (Romanov x Rahmani) lambs (about 8 months old and 33 kg LBW) were assigned into four groups. Lambs in all groups were fed diets containing differed sources of 50% of protein in concentrate feed mixture, being sun flower meal in the 1st group (control, G1), CSM in G2, SBM in G3 and DDGS in G4 for 120 days as an experimental period. At the end of the experimental period, lambs were slaughtered and testes were collected for morpho-histological study. Blood was collected for testosterone determination in blood serum and epididymal spermatozoa were recovered by slicing. Results revealed that testicular weight and size in terms of length and width were the highest (P<0.05) in G3, moderate in G1 and G2 and the lowest in G4. Dietary protein source had insignificant effect on weight and measures of epididymis or its segments, in particular length and width of epididymal cauda testes of G3 showed higher (P<0.05) values of the largest and smallest diameters and the widest average diameter of the seminiferous tubules (ST) and the highest (P<0.05) thickness of spermatogenic layer as compared to other groups. The largest, smallest and average diameters of epididymal cauda ductules (ED) was higher (P<0.05) and the lining epithelial layer of epididymal cauda was thicker (P<0.05) in G3 and G4 than in G1 and G2. Percentages of progressive motility and livability of spermatozoa recovered from the epididymal cauda were the highest (P<0.05) in G3, moderate in G1 and G2, and the lowest in G4. Percentages of abnormality and acrosome damage of epididymal spermatozoa were not affected by dietary protein source. Serum testosterone concentration was the highest (P<0.05) in G3 and the lowest in G4. In conclusion, feeding CSM or DDGS should not be supplied to growing male lambs for breeding. Feeding diet containing sun flower meal (Control diet) or soybean meal as sources of dietary protein had save effect on growing male lambs for breeding.

&lt;b&gt;Nutrient intake, productive performance and body measurements of dairy heifers fed with different sources of protein&lt;/b&gt; - doi: 10.4025/actascianimsci.v35i3.18749

This study evaluated the effect of different protein sources (soybean meal, cottonseed meal, peanut meal and sunflower meal) on dry matter and nutrient intake, productive performance and body measurements of dairy heifers, Holstein x Zebu, recreated in confinement. The experiment consisted in a randomized complete block design made up by 6 replications and 4 treatments. The mean values of ingestion of ether extract (EEI, kg day -1 ) were statistically different (p < 0.05). The neutral detergent fiber intake (NDFI, %BW) also presented differences (p < 0.05), with higher values in the diet containing sunflower meal (1.01% BW) in relation to the diet with soybean meal (0.84% BW). The average daily weight gain using the diet with soybean meal was superior (0.95 kg day -1 ) to the diet with sunflower meal (0.82 kg day -1 ), and considering the final body weight, the diet with soybean meal was superior to the other treatments (p < 0.05). The heart girth presented greater association with body weight (0.93). The soybean meal promoted the best productive performance of crossbred Holstein x Zebu heifers fed diets based on sugarcane. However, cottonseed meal, peanut meal and sunflower meal can be possible alternatives to soybean meal.

Effect of different protein sources on satiation and short-term satiety when consumed as a starter.

BackgroundBecause the source of protein may play a role in its satiating effect, we investigated the effect of different proteins on satiation and short-term satiety.MethodsTwo randomized single-blind cross-over studies were completed. In the first study, we investigated the effect of a preload containing 20 g of casein, whey, pea protein, egg albumin or maltodextrin vs. water control on food intake 30 min later in 32 male volunteers (25 ± 4 yrs, BMI 24 ± 0.4 kg/m2). Subjective appetite was assessed using visual analogue scales at 10 min intervals after the preload. Capillary blood glucose was measured every 30 min during 2 hrs before and after the ad libitum meal. In the second study, we compared the effect of 20 g of casein, pea protein or whey vs. water control on satiation in 32 male volunteers (25 ± 0.6 yrs, BMI 24 ± 0.5 kg/m2). The preload was consumed as a starter during an ad libitum meal and food intake was measured. The preloads in both studies were in the form of a beverage.ResultsIn the first study, food intake was significantly lower only after casein and pea protein compared to water control (P = 0.02; 0.04 respectively). Caloric compensation was 110, 103, 62, 56 and 51% after casein, pea protein, whey, albumin and maltodextrin, respectively. Feelings of satiety were significantly higher after casein and pea protein compared to other preloads (P < 0.05). Blood glucose response to the meal was significantly lower when whey protein was consumed as a preload compared to other groups (P < 0.001). In the second study, results showed no difference between preloads on ad libitum intake. Total intake was significantly higher after caloric preloads compared to water control (P < 0.05).ConclusionCasein and pea protein showed a stronger effect on food intake compared to whey when consumed as a preload. However, consuming the protein preload as a starter of a meal decreased its impact on food intake as opposed to consuming it 30 min before the meal.

Optimizing growth of Lactobacillus reuteri in phytone peptone‐tryptone‐glucose medium by using response surface methodology

Lactobacillus reuteri as probiotic helps prevent and treat both viral and bacterial diarrhea enhancing the body's resistance to gastrointestinal disease. However, the growth of L. reuteri is very limited and certain nutrients are needed for optimum growth and high cell density. The objectives of this study were to determine the effect of different protein sources on growth and bacterial cell density of L. reuteri and to assess the optimum growth requirements using response surface methodology. Four strains (CF 2‐7F, MF 14 C, DSM 20016, and SD 2112) of L. reuteri were used in this study. Overnight cultures were inoculated into fresh basal growth broth with various proteins sources (peptone, tryptone, proteose peptone, phytone peptone, tryptic soy broth, yeast extract, and beef extract). Samples were then mixed well and incubated at 37 °C for 48 hrs. Bacterial growth was monitored by measuring turbidity at 610 nm in a spectrophotometer at different time intervals during the incubation period. At the end of incubation, samples were plated on MRS agar to determine the bacterial population. Our results showed that phytone peptone or tryptone promoted the growth of L. reuteri (P &lt; 0. 01) compared to the control. The response surface model indicated that phytone peptone (5–10 g/L), tryptone (5 g/L), and glucose (15g/L) could be used as optimum concentrations to enhance the growth and cell density of L. reuteri in growth medium.
