“…There were no significant (P≥0.05) differences across the different dietary treatments in serum levels of total protein, globulin and triglycerides. These results are in line with the results obtained by [27] who reported that inclusion of yeast into diets of turkey toms doesn't affect serum levels of total protein, globulin and triglycerides. Reference [28] also, found serum levels of protein and triglycerides were unaffected by dietary S cerevisiae.…”

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.

“…However, supplemental LY failed to induce modifications of growth performance in broilers during normal period or stress period. This result was similar to the previous studies (Heugten et al 2003;Konca et al 2009). Contradictorily, it was also reported that LY addition was associated with the promotion of growth in broilers (Haldar et al 2011).…”

The effects of live yeast (LY) on immune responses and intestinal morphological structure in lipopolysaccharide (LPS) challenged broilers were investigated. A total of 480 one-day-old male broilers were divided into six groups following a 3 × 2 factorial arrangement (eight replicates) with three dietary LY dosages (0%, 0.05%, or 0.50%) and two immune treatments (injection of saline or LPS) given at an interval of 48 h between 21 and 27 d of age. Blood was sampled on days 21 and 27, while intestine were collected on day 28. Results showed that LPS damaged (P ≤ 0.05) intestinal histomorphology, and tended to reduce (P = 0.071) serum anti-Newcastle disease virus (NDV) titers on day 21, but increase (P = 0.089) jejunal maltase activity. Supplemental LY at 0.05% elevated (P ≤ 0.05) ileal villus width and villus surface area, and serum anti-NDV titers on day 21. The addition at 0.50% increased (P ≤ 0.05) jejunal and ileal villus height to crypt depth ratio, reduced (P ≤ 0.05) jejunal maltase activity and crypt depth, and attenuated (P ≤ 0.05) LPS-induced increase (P ≤ 0.05) in serum diamine oxidase activity on day 21. Collectively, supplemental LY at 0.05% improved antibody response and the addition at 0.50% alleviated LPS-induced intestinal damage in broilers.

“…Several study reported that either MOS from yeast cell walls (Kim et al, 2011) or MOS from palm cernel (Fernandez et al, 2002) reduced the population of E.coli significantly compared with control feed. In agreement with our results, in a comparative study, Chee et al (2010) and Biggs et al (2007) reported that supplementation of MOS in diet did not reduce the population of E.coli in the intestine of broilers, while Konca et al (2009) reported that supplementation of MOS in diet did not reduce the population of E.coli in the intestine of turkey.…”

Mannan-oligosaccharides (MOS) is a common prebiotics used as a feed additives. The use of antibiotic can be replaced by MOS to reduce the number of pathogenic bacteria in small intestines of chickens. The objective of this study was to determine the effect of MOS extracted from copra meal on intestinal microbial population and blood profile of broiler chickens. The study was conducted by using 150 day-old male broiler chickens (average body weight 46.00 + 1.41 g). The design of this experiment was a completely randomized design (CRD) with 3 dietary treatments, 5 replications and 10 birds in each replication. The dietary treatments consisted of control diet (corn-soybean meal diet without supplementation of antibiotic and prebiotic), control + 0.1% antibiotic bambermycin, and control + 0.035% MOS. For the first 4 weeks the birds were fed treatment diets, followed by commercial feed for 2 weeks. The parameters observed in this study were intestinal microbes population and blood profiles. The results showed that the administration of 0,035% MOS increased the lactic acid bacteria (LAB) number compared with antibiotics feed (P<0.05), but not significantly different (P >0.05) with the control group. The total aerobic and coliform bacteria were higher in MOS and antibiotic treatment compared than control group. The supplementation of 0.035% MOS from copra meal in diet increased the level of leucocytes which is important to immune response of broilers and its usage was safe because the level of chicken blood profile were within the normal range.
