Influence of yeast hydrolysate supplement on growth performance, nutrient digestibility, microflora, gas emission, blood profile, and meat quality in broilers
A total of 1512 Ross 308 broilers (one - day - old) were assigned (random blocks) to 1of 3 dietary treatments with 28 replicates of 18 chicks/cage. The dietary treatments were Corn-soybean-meal based basal diet supplemented with 0%, 0.1%, a...

The dietary treatments were Corn-soybean-meal based basal diet supplemented with 0%, 0.1%, and 0.2% of commercial yeast hydrolysate (YH [Saccharomyces cerevisiae]). The graded level of YH supplementation has linearly increased broilers body weight gain on d 21, 35, and overall (p = 0.044, 0.029, and 0.036, respectively) experimental period. In addition, the increased level of YH supplementation has linearly reduced feed conversation ratio of broilers on d 21, 35, and overall trial period (p = 0.041, 0.052, and 0.032, respectively). However, the feed intake and mortality of broilers were not affected by the graded level of YH supplementation. Though nutrient digestibility of dry matter (p = 0.012) and nitrogen (p = 0.021) was linearly increased in broilers fed YH supplementation, at the end of the trial it fails to affect the total track digestible energy. Dietary inclusion of YH supplementation showed a beneficial effect on the microbial population as linearly improved lactobacillus (p = 0.011) and reduced Escherichia coli counts (p = 0.042). An increasing level of YH supplementation has tended to decrease NH3 (p = 0.069) and linearly decrease H2S (p = 0.027) of noxious gas emission in broilers. Moreover, dietary YH supplements trend to increase the glucose (p = 0.066) and reduced cholesterol (p = 0.069) level. At the end of the test, YH supplementation elicited a linear reduction in drip loss on days 5 and 7, respectively (p = 0.045, and 0.021). Furthermore, dietary inclusion of YH supplementation had linearly increased villus height (p = 0.051) but fails to affect crypt depth. Therefore, in terms of positive effects on the broiler’s overall performance, we suggest that dietary supplements containing graded YH levels in the broilers diet could serve as a potential alternative for growth promoters.http://www.ejast.org/archive/view_article?pid=jast-63-3-563yeast hydrolysatebrewer yeastbroilersgrowth performance |

A total of 1512 Ross 308 broilers (one - day - old) were assigned (random blocks)
to 1of 3 dietary treatments with 28 replicates of 18 chicks/cage. The dietary
treatments were Corn-soybean-meal based basal diet supplemented with 0%, 0.1%,
and 0.2% of commercial yeast hydrolysate (YH [Saccharomyces
cerevisiae]). The graded level of YH supplementation has linearly
increased broilers body weight gain on d 21, 35, and overall (p
= 0.044, 0.029, and 0.036, respectively) experimental period. In addition, the
increased level of YH supplementation has linearly reduced feed conversation
ratio of broilers on d 21, 35, and overall trial period (p =
0.041, 0.052, and 0.032, respectively). However, the feed intake and mortality
of broilers were not affected by the graded level of YH supplementation. Though
nutrient digestibility of dry matter (p = 0.012) and nitrogen
(p = 0.021) was linearly increased in broilers fed YH
supplementation, at the end of the trial it fails to affect the total track
digestible energy. Dietary inclusion of YH supplementation showed a beneficial
effect on the microbial population as linearly improved
lactobacillus (p = 0.011) and reduced
Escherichia
coli counts (p = 0.042). An increasing level
of YH supplementation has tended to decrease NH3 (p
= 0.069) and linearly decrease H2S (p = 0.027) of
noxious gas emission in broilers. Moreover, dietary YH supplements trend to
increase the glucose (p = 0.066) and reduced cholesterol
(p = 0.069) level. At the end of the test, YH
supplementation elicited a linear reduction in drip loss on days 5 and 7,
respectively (p = 0.045, and 0.021). Furthermore, dietary
inclusion of YH supplementation had linearly increased villus height
(p = 0.051) but fails to affect crypt depth. Therefore, in
terms of positive effects on the broiler’s overall performance, we
suggest that dietary supplements containing graded YH levels in the broilers
diet could serve as a potential alternative for growth promoters. |
