Effects of Brewer's Yeast Slurry on the Growth and Blood Composition of Broiler Chicks
맥주효모 슬러리의 급여가 육계의 성장과 혈액 성상에 미치는 영향
Abstract
This study was conducted for a period for 5 weeks in order to evaluate effects of brewer's yeast slurry(BYS) on the growth performance, organ development and blood composition of broiler chicks. A total number of 84 one day old broiler chicks were allocated to one of three supplemented diets: 0%(control), 2% and 4% BYS. Body weight gain and feed efficiency of chicks fed the diet supplemented with 4% BYS significantly was increased by 9% and 8%, respectively, compared to the control diet(P<0.05). The BYS supplements did not affect weights of liver, heart and abdominal fat, and their ratios per body weight. However, in 4% BYS supplement group, ratio of liver to body weight significantly decreased(P<0.05) by 12%, compared to the control. The supplement of 4% BYS decreased the concentration of triglyceride by 31%, and increased the concentration of high density lipoprotein(HDL) by 26%, compared to the control(P<0.05). These results indicated that the supplementation of 4% BYS in diet can improve body weight gain as well as feed efficiency, and increased the concentration of blood HDL, and ratio of HDL to total-cholesterol of broiler chicks.
