“…In the present work, however, coarse diets had no influence on cecal biogenic amines concentrations, but there was a decrease in total BCFA, mainly isovaleric acid, which is produced as a result of bacterial fermentation of leucine. The improved performance in broilers fed BA-supplemented diets is in accordance with previously reported broiler studies (Antongiovanni et al., 2009 ; Adil et al., 2010 ; Pouraziz et al., 2013 ).

“…Pouraziz et al. ( 2013 ) reported approximately 8 and 6% improved BW and FCR, respectively, in broilers fed a diet with 0.004 g/g BA glycerides compared with broilers fed a control diet in both starter and grower phases. These positive effects of BA supplementation may be due to improved digestion and absorption of nutrients (Mansoub, 2011 ), as a consequence of increased pancreatic enzyme secretion, and because of their effects on gut mucosa and their antimicrobial activity (Adil et al., 2010 ).…”

An experiment with 288 male (Ross 308) 1-d-old broilers was conducted to test the hypothesis that a coarse diet supplemented with butyric acid (BA) and fermentable carbohydrates (FC) improves performance of broilers with a poorly digestible protein source. The interaction effects of diet structure (fine or coarse), FC supplementation (with or without), and BA supplementation (with or without) in a poorly digestible diet based on rapeseed meal (RSM) were tested in a factorial arrangement of 8 (2 × 2 × 2) dietary treatments. The coarseness of the diet affected feed intake (FI) (P < 0.001), BW gain (P = 0.001), and the feed conversion ratio (FCR) (P = 0.001) positively. Broilers fed the coarse diets had, on average, 14% heavier gizzards and 11, 7, 5, and 6% lower relative empty weights of the crop, duodenum, jejunum, and ileum, respectively, compared with those fed the fine diets. Dietary coarseness resulted in, on average, 6% greater ileal protein digestibility, 20% lower gizzard pH, 19% greater villus height, 18% lower crypt depth, and 23% reduced cecal branched chain fatty acids (BCFA) compared with chickens fed the fine diets. Broilers fed BA-supplemented diets had an improved FCR (P = 0.004) and decreased crypt depth (P < 0.001) compared with those fed diets without BA. Fermentable carbohydrate supplementation did not influence growth performance, gut development, or contents of total BCFA and total biogenic amines in the cecal digesta (P > 0.05). Supplementation with FC, however, decreased the cecal concentration of spermine by approximately 31% compared with broilers fed diets without FC (P = 0.002). In conclusion, feeding a coarse diet supplemented with BA improved performance of broilers fed a diet containing a poorly digestible protein source. The negative effects of a poorly digestible protein source can thus be partly counterbalanced by coarse grinding and BA supplementation in the diet.

“…Reference [28] also, found serum levels of protein and triglycerides were unaffected by dietary S cerevisiae. In addition, reference [29] declared that there is no significant influence of dietary S cerevisiae on serum triglycerides. In reverse to these findings, [26] noticed that dietary yeast decreases serum triglycerides and increases serum concentrations of protein and globulin.…”

Abstract:This study was conducted to evaluate the effect of feeding graded levels of yeast on broiler performance, carcass characteristics and some hematological indices. One day old Hubbard broiler chicks (n=160) were randomly allocated to five dietary treatments. Each treatment consisted of 4 replicates of 8 broilers each. The dietary treatments contained 0% yeast (Saccharomyces cerevisiae) as a negative control diet, 0% yeast + 30 ppm Oxytetracyline as a positive control, 1%, 2% and 3% yeast in the starter and finisher diets. During the experimental periods of 6 weeks, feed intake, body weight gain and feed conversion ratio values were calculated. At the end of the experimental period (6 weeks of age), some biochemical and hematological indices, carcass characteristics traits and internal organs weights were recorded. Growth performance parameters were significantly (P≤0.05) affected by experimental diets. Chicks fed either 0 or 3% yeast recorded the highest (P≤0.05) feed intake, however, the best (P≤0.05) body weight gain was obtained by birds fed 0 or 1% dietary yeast compared to the positive control diet. The highest (P≤0.05) feed conversion ratio was reported for birds fed the positive control diet and 3% dietary yeast compared to the negative control diet. The inclusion of different dietary treatments had no significant (P≥0.05) effects on dressing percentage, hot base and relative weights of heart, gizzard and abdominal fat. Nevertheless, birds fed 3% dietary yeast showed significant (P≤0.05) decrease in the relative weight of the liver compared to the negative control diet. Relative weights of breast and thigh were significantly (P≤0.05) higher in birds fed 1% yeast than those fed 3% yeast. There were linear decreases in serum cholesterol and albumin of broilers fed graded levels of dietary yeast. It is concluded that yeast can be included in broiler diet at 1% without detrimental effects on performance, and could therefore serve as a natural substitute for antibiotics.

“…In current study, the broiler fed with phytase alone, different concentration of S. cerevisiae, and phytase with different concentration of the yeast combination had lower plasma triglyceride, total cholesterol, LDLcholesterol, glucose, calcium and GGT enzyme, they had higher HDL-cholesterol, phosphorus and ALT enzyme. S. cerevisiae cell wall component, the beta glucan, had a cholesterol lowering effect was documented by some researchers 15,34,36 . These researchers suggested that yeast may regulate the serum cholesterol concentrations by deconjunction of bile acids.…”

Saccharomyces cerevisiae and phytase can be used as a feed supplement in combination or alone for broiler feeding. An experiment was performed to study the effect of supplemental different ratio S. cerevisiae and phytase combination on growth performances, plasma biochemical parameters and plasma enzyme activities of broiler chickens. Animal were feed ad libitum through the study. Sixty hundred 1 day-old broiler chicks were randomly selected and distributed into eight groups as control (C); phytase (P) (added 200 g Pyhase to 1000 kg of diet); S. cerevisiae (Y1) (added 0.1% S. cerevisiae of the diet); Y1+P (combination of group Y1 and P); S. cerevisiae (Y2) (added 0.2% S. cerevisiae of the diet); Y2+P (Combination of Y2 and P); Y4 (added 0.4% S. cerevisiae of the diet); Y4+P (Combination of Y4 and P) respectively. At the end of the study, blood samples were collected from 15 randomly selected broiler chickens from each group through the brachial vein on the 42 nd day of the experiment. Plasma were separated and used for measurement of plasma biochemical parameters and enzyme activities. S.cerevisiae alone and combination of Phytase and S. cerevisiae increased body weight and body weight gain of broiler, especially in 6 th week, except in group Y4. Although, the broiler chickens supplemented with just phytase or/and S. cerevisiae and their combination had lower plasma triglyceride, total cholesterol, LDL-cholesterol, glucose, calcium and GGT enzyme activity , they had higher HDL-cholesterol, phosphorus and ALT enzyme. Moreover, supplementation with just phytase or/and S. cerevisiae and their combination did not change the hematocrit, plasma total protein and AST enzyme levels of the broiler chickens. These results demonstrated that phytase and S. cerevisiae alone or/and their combination improved growth performance and body weight gain of the broiler chickens. So, S.cerevisiae and phytase combination may be used as an growth enhancer. However, more studies would be necessary to obtain the effects of supplementing yeast and phytase combination on growth.
