Abstract: The study was conducted to ascertain the effect of supplemental tryptophan on uterine histomorphological structures of white Leghorn layers. 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. At the end of the study, oviducts from six birds per treatment were dissected out and gross morphometrical parameters like length and weight were recorded. For histological studies, after tissue preparation and staining with H&E, histological layer of uterus was studied. Our data analysis indicated that the total weight and length of various segments of oviduct did not differ by tryptophan supplementation. The histological layers of uterus were also not altered by tryptophan supplementation.
