Abstract

Nath, Babu Kanti, Akter, Nasima, Hossain, Mohammad Abul, Najmin, Shamima, Nath, Chandan and Hossain, Md. Emran. 2020. Effects of graded levels of baker's yeast on performance, gut morphology and hemato-biochemical indices of broiler chickens. Indian Journal of Poultry Science, 55(2): 105–113.

The study was directed to explore the impacts of graded levels of baker's yeast (Saccharomyces cerevisiae) on performance, carcass attributes, gut morphology, and hemato-biochemical indices of industrial broiler birds. Two hundred forty-old-unsexed Cobb 500 broiler chicks were randomly distributed into four unique feeding regimens designated as T0 (0% Yeast), T1 (2% Yeast), T2 (2.5% yeast) and T3 (3% yeast) following completely randomized design. Birds were raised on litter up to 5th wk of age. Supplementation of baker's yeast had no significant effect (P>0.05) on feed intake and weight gain of the broiler chickens. However, FCR improved (P°0.05) at 3rd week of age. Villus height and cryptal profundity were expanded significantly (P°0.05). Hemoglobin, red blood cell, packed cell volume, erythrocyte sedimentation rate stayed unaltered (P>0.05) due to yeast supplementation. Serum concentrations of triglycerides, cholesterol, aspartate transaminase, alanine transaminase, calcium, total protein, and uric acid were not significantly altered (P>0.05) to the dietary regimens. It was concluded that the usage of elevated levels of baker's yeast in the diet of the industrial broiler promoted FCR and gut morphology without influencing carcass attributes and hemato-biochemical indices. Supplementation of baker's yeast above 2% reveals no extra benefit.
