Abstract:

The study was conducted to determine the effect of dietary supplemental tryptophan on the levels of blood biochemical parameters namely glucose, total cholesterol, total protein, albumin and globulin. A total of 350 White Leghorn layers of 18 weeks were allocated to seven experimental groups, each of which included 5 replicates and reared upto 45 weeks of age. Experimental diets consisted of two protein diets along with 5 supplemental levels of tryptophan. The basal diet consisted of normal protein (CP-17 %) with 0.165 % tryptophan and low protein diet with 0.153 % tryptophan. Tryptophan was supplemented at 0.012, 0.015 and 0.035 % in normal protein diet to obtain 0.165 %, 0.18 % and 0.20 % digestible tryptophan and at 0.027 %, 0.047 % in low protein diets (CP- 16.23 %) to obtain 0.18 % and 0.20 % digestible tryptophan respectively. Blood was collected from the birds at monthly intervals and plasma was separated to analyse glucose, total cholesterol, total protein and albumin using UV spectrophotometer. The results of the study indicate that increasing tryptophan levels at 0.18 and 0.20 % had significantly (P<0.01) decreased plasma cholesterol and increased total protein and albumin levels, whereas plasma glucose levels did not vary due to tryptophan levels.
