Effect of dietary supplementation of different levels of saccharomyces cerevisiae on growth performance and hematology in broiler

摘要

Present study was planned to highlight the effects of inclusion of different levels of Saccharomyces Cerevisiae (SC) in broiler feed, on growth performance, hematology and farm economics. One hundred and fifty, one day old broiler chicks (Hubbard) were divided into five groups; each group was subdivided into three replicates of 10 birds each. Starter (CP 20% and ME 2860 Kcal/Kg) and finisher (CP 18.75% and ME 3000 Kcal/Kg) diets were fortified with levels of SC at 0.0, 0.5, 1.0, 1.5 and 2.0 g/Kg to prepare diets A, B, C, D and E respectively. Each dietary treatment was allotted to three replicates. Weight gain, feed consumption and feed conversion ratio improved significantly (p<0.05) as a result of feeding diet D containing 1.5 g/Kg SC in comparison to all other treatments. Dietary inclusion of SC significantly (P<0.05) reduced the levels of blood glucose and cholesterol in the birds of all treated groups when compared to those of control group. Maximum reduction in glucose and cholesterol levels was observed in the birds of treatment group D using SC @ 1.5g/Kg diet as compared to those of other treatment groups. Values regarding hemoglobin, PCV and DLC of the birds remained unaffected by dietary inclusion of SC in all treatment groups. However, numerical values of Hb and PCV in the birds consuming diet supplemented with 1.5g/Kg SC were apparently higher than those of control group. The treatment group D using SC @ 1.5g/Kg proved to be cost effective and fetched more profit per kg live weight which positively affected the farm economics.
