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.
