This study was conducted to determine the chemical composition and rumen degradabiUty characteristics of modified dried vinasse (ProMass) originating from bakers yeast production and to investigate its effects on steer performance, carcass characteristics and some blood parameters. This additive compound with an elevated metabolizable energy (2 800 kcal/g) contained a marked proportion of crude proteins which were remarkably rich in glutamic acid. The degradation of dry matter and organic matter measured in rumens from 4 crossed sheep was very high (about 900 g/kg) during the first 4 hours and the ProMass crude protein was markedly soluble. Forty-five steers were randomly allotted in 3 equal groups according to the mixed diet regimen (concentrates plus forage): concentrates supplemented with 40 g/kg or 80 g/kg ProMass were distributed to assay groups for 24 weeks whereas one group was not supplemented and served as negative control. Growth performance and food efficiency was slightly increased but not significantly in supplemented steers and faecal moisture and serum biochemical profiles (urea, protein and cholesterol concentrations and AST, ALT and ALP activities) were unchanged compared to controls. ProMass supplementation has induced significant reductions of the heart and pelvic fat weights whereas the dressing percentages and the other carcass characteristics remained unaffected. These results showed that ProMass supplies highly soluble proteins, can be included in the steer ration up to 80 g/kg without adverse effects and would promote fat utilization.

This study was conducted to determine the nutritive value of live yeast culture (RumiSacc, Saccharomyces cerevisiae) and to investigate its effects on milk yield, milk composition and some blood parameters in lactating cows. Six muciparous Holstein cows were allocated to two groups of three cows and assigned randomly to one of two diets in a cross-over experiment. Daily 50 g RumiSacc was top dressed at the p.m. feeding for the treatment group. RumiSacc supplied a high protein and energy with high organic matter digestibility values (83.35%) determined by in vitro enzymatic analysis. Yeast culture supplementation significantly increased milk yield, tended to increase fat yield, protein yield and lactose yield of milk. Methylated fatty acid level of 18:3 (n-3) in milk fat was increased by yeast culture supplementation. The concentrations of methionine, phenyalanine, tyrosine, tryptophan and taurine were significantly increased with dietary inclusion of yeast culture. Live yeast culture supplementation did not affect other performance characteristics, milk quality characteristics and blood parameters. As a conclusion live yeast culture (RumiSacc, Saccharomyces cerevisiae) had high nutritive value and positive effects on milk production and some milk quality characteristics in lactating cows under field conditions.

This study was conducted to determine the effects of dietary yeast autolysate on performance, carcass and gut traits, blood parameters, and humoral immune response of broilers. A total of 175 day-old Ross 308 male broiler chicks were allocated into one control group and 4 treatment groups each containing 5 replicate groups of 7 chicks. A basal diet was supplemented with 0, 1, 2, 3, and 4 g/kg of yeast autolysate (Saccharomyces cerevisiae, InteWall) to generate dietary treatments. The experimental period lasted 42 d. Supplemental yeast autolysate improved live weight gain (P < 0.01) and feed conversion (P < 0.001) during the starter period (1 to 21 d). Cumulative FCR was decreased (P < 0.05) during the overall period (1 to 42 d) with 2 and 3 g/kg of yeast autolysate supplementation when compared with the control diet. There were no dietary effects on final live weight, feed intake, excreta pH, excreta moisture, carcass yield, and the relative weight of gizzard, liver, heart, spleen, bursa of Fabricius, and the intestinal weights. Yeast autolysate supplementation decreased relative weight of abdominal fat (P < 0.001) and Escherichia coli count of the digesta (P < 0.01) and increased antibody titers to SRBC (P < 0.001). The pH of jejunal and ileal digesta was decreased at the 2, 3, and 4 g/kg of yeast autolysate supplementation compared with that of birds fed the control diet (P < 0.001). Dietary treatments did not significantly affect blood serum levels of cholesterol, triglyceride, protein, uric acid, aspartate amino transferase, and alanine amino transferase. It was concluded that the dietary supplementation at the level of 2 and 3 g/kg of yeast autolysate was an effective feed additive in broiler feeding because of the increased growth performance, increased immunocompetence, and the reduction of E. coli colonization in the intestine. © Poultry Science Association, Inc.

This study was designed to determine the effects of using yeast autolysate and black cumin seed in laying hen diets on laying performance, egg traits, some blood characteristics and antibody production to sheep red blood cells (SRBC). A total of 112 Brown Nick laying hens, 23. wks of age, were allocated to one of 4 diet groups in 2 levels of yeast autolysate (0 and 2. g/kg, Saccharomyces cerevisiae, InteWall) and 2 levels of black cumin seed (0 and 15. g/kg, Nigella sativa L.) for 18. wks according to a 2 × 2 factorial arrangement. Each group was divided into 7 replicates of 4 hens each. The diets were formulated to be isocaloric and isonitrogenous. Dietary treatments did not affect body weight, feed intake, egg production, mortality, excreta moisture, interior and exterior egg quality characteristics, egg yolk triglyceride or yolk malondialdehyde concentration. Yeast autolysate supplementation improved (P < 0.05) egg weight and feed efficiency but the usage of black cumin seed in the diets decreased (P < 0.05) egg weight. Dietary yeast autolysate or black cumin seed decreased egg yolk cholesterol level, blood serum levels of cholesterol, triglyceride and aspartate amino transferase (AST) and increased blood serum levels of alkaline phosphatase (ALP) and antibody titers to SRBC. The ratio of monounsaturated fatty acids (MUFA) to saturated fatty acids (SFA) increased with black cumin seed. It is concluded that 2. g/kg yeast autolysate (Saccharomyces cerevisiae) or 15. g/kg black cumin seed (Nigella sativa L.) had beneficial effects on egg cholesterol content and humoral immune response. The usage of yeast autolysate also improved egg weight and feed efficiency. The significant interactions were found in egg yolk cholesterol and anti SRBC titer between the usage of yeast autolysate and black cumin seed. © 2012 Elsevier B.V.

BACKGROUND: The objective of this study was to determine the effects of dietary yeast autolysate on performance, egg traits, egg cholesterol content, egg yolk fatty acid composition, lipid oxidation of egg yolk, some blood parameters and humoral immune response of laying hens during a 16 week period. A total of 225 Hyline Brown laying hens, 22 weeks of age, were allocated equally to one control group and four treatment groups. Yeast autolysate (Saccharomyces cerevisiae, Inte Wall) was used at levels of 1, 2, 3 and 4 g kg-1 in the diets of the first, second, third and fourth treatment groups respectively. RESULTS: Dietary treatments did not significantly affect body weight, feed intake and egg traits. Yeast autolysate supplementation increased egg production (P < 0.001) and egg weight (P < 0.001) and improved feed efficiency (P < 0.05). Yeast autolysate at levels of 2, 3 and 4 g kg-1 decreased egg yolk cholesterol level as mg g-1 yolk (P < 0.01) and blood serum levels of cholesterol and triglyceride (P < 0.05) and increased antibody titres to sheep red blood cells (P < 0.01). Total saturated fatty acids and the ratio of saturated/unsaturated fatty acids increased (P < 0.01) and total monounsaturated fatty acids (P < 0.001) decreased with yeast autolysate supplementation. CONCLUSION: Dietary yeast autolysate at levels of 2, 3 and 4 g kg-1 had beneficial effects on performance, egg cholesterol content and humoral immune response.It is concluded that 2 g kg-1 yeast autolysate will be enough to have beneficial effects in laying hens. © 2010 Society of Chemical Industry.
