“…Meat composition affects the nutritional value of meat and also the quality of meat products. Konca et al 26 reported that dietary supplementation with MOS did not affect dry matter, crude ash, and crude protein of breast meat of turkeys, which is in agreement with present finding.…”

Background: One of the most important foodborne pathogen which causes enteritis is Salmonella enteritidis (SE). Human cases are mostly associated with the consumption of eggs and poultry meat. Objective: An experiment has been carried out to evaluate the impacts of a yeast product as liquid prebiotic on bacterial shedding, performance indices, and some breast meat characteristics of broiler chickens challenged with SE. Materials and Methods: A total of 90 one-day-old male broiler chicks (Ross 308) were randomly assigned to three different groups with three replicates for each treatment. The treatments were as follows: (1) CONT: birds were not challenged, (2) SE: birds were challenged with SE and fed with a control diet without prebiotic, and (3) SE+PREB: birds were challenged with SE and fed with liquid prebiotic. The challenge with SE was performed on birds in groups 2 and 3 at 28 days of age. Performance parameters and Salmonella shedding were determined on days 7 and 14 post infection. Twelve birds per treatment were sampled at the end of the trial for evaluating characteristics of breast meat. Results: The challenged birds which received prebiotic showed significantly higher body weight gain, lower feed intake, and lower SE shedding than SE group (P<0.05). No significant differences were seen in meat characteristics. Conclusion: Prebiotics can have beneficial effects even if they are used in the diet at an unusual time. The supplementation of yeast product can improve some performance parameters and reduce bacterial shedding in SE challenged chicken.

“…The dietary treatments with MOS did not affect pH of breast meat of turkeys. 26 Takahashi et al 27 reported that diet supplementation with probiotics and prebiotics in broilers did not have any significant effect on cooking loss of breast meat. Breast muscle is the greatest edible part and also the most valuable part of broilers carcass.…”

“…The addition of MOS resulted in a higher (P ≤0.010) carcass weight and lower liver percentage, but had no effect (P >0.050) on the other parameters. In similar experiments Bozkurt et al (2008), Ghosh et al (2008), Konca et al (2009) and Sarica et al (2009) reported no significant improvement in birds due to the supplementing of MOS on carcass weight, carcass dressing percentage or carcass part percentage. The birds that consumed CPr had lower (P ≤0.050) carcass dressing percentage, but the addition of CPr in the feed had no effect (P >0.050) on the other measured parameters.…”

The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation. Three hundred, 1-day old Japanese quail were divided into four groups with three replicates each. One group that served as control received the basal diet. The three experimental diets consisted of the basal diet to which either 6 g CPr/kg, 2 g MOS/kg or both 2 g MOS/kg and 6 g CPr/kg was added. The body weight, feed consumption, feed conversion ratio (kg feed/kg weight gain) and mortality were examined at weekly intervals. At the end of the 42-day feeding period the birds were slaughtered, the carcasses were processed and the carcass weight, carcass dressing percentage and carcass part percentages were calculated. Also, the breast meat composition and its fatty acid profile were analyzed. Results showed that the female quail had a higher body and carcass weight and liver to live weight percentage, whereas they had lower carcass dressing percentage than males. The dietary addition of MOS increased body and carcass weight, whereas it decreased liver to live weight percentage and crude fat content of the breast meat. The dietary addition of CPr lowered carcass dressing percentage and ash content of the breast meat. Interactions between the two examined supplements were observed in feed consumption, feed conversion ratio and carcass weight. An interaction between MOS and sex was observed on carcass weight. It was concluded that MOS and calcium propionate can be used effectively in Japanese quail diets. ________________________________________________________________________________

“…boulardii in diets fed to Turkey poults. On the contrary, Konca et al [27], noticed that finishing turkey fed diets containing 1 g/kg mannan oligosaccharide and 1 g/kg live yeast did not affect performance at 10 to 20 weeks of age. The reason behind these differences in research findings could be attributed to differences in the breed of bird used, ingredient/diet composition, form or type of yeast used as well as the age of the birds.…”

Objective: This study evaluated the effect of yeast products on growth performance, visceral organ weights, endogenous enzyme activities, ileal nutrient digestibility and meat yield of broiler chickens fed diets containing autolyzed whole yeast (WY) and yeast cell walls (YCW) at varying levels of inclusion.Methods: Nine dietary treatments consisting of WY or YCW included at 0.5, 1.0, 1.5, or 2.0 g/kg diet and a control diet without yeast supplementation was used in the experiment. Each of the nine treatments was replicated six times with nine birds per replicate. Birds were housed in cages, in climate-controlled rooms and fed starter, grower and finisher diets.Results: There was an improvement (p<0.05) in body weight gain and feed conversion ratio on d 10, 24, and 35 for birds fed 1.0 to 2.0 g/kg WY or YCW diet. Small intestine weight was heavier on d 10 and 24 for birds on higher levels of WY and YCW compared to the control group. On d 10 and 24, there was a significant increase (p<0.05) in tissue protein content and pancreatic enzyme activities (trypsin and chymotrypsin) of birds on 1.5 to 2.0 g/kg WY and YCW diets compared to the control group. Compared to the control group, birds on WY (2.0 g/kg diet) and YCW (at 1.5 and 2.0 g/kg diet) had better (p<0.05) protein digestibility on d 24. On d 35, there was significant improvement (p<0.05) in percentage of carcass, absolute and relative breast weight for broiler chickens fed WY and YCW mostly at 2 g/kg diet compared to birds on the control diet.Conclusion: Supplementation of diets with autolyzed WY and YCW products especially at 1.5 to 2.0 g/kg diet improved broiler chicken performance and meat yield through their positive effects on ileal protein digestibility and pancreatic enzyme activities.
