Abstract

The aim of this was to find the intestinal histological alterations in chickens under the influence of threonine  (Thr) and vitamin A treatment. A total 60 one day old birds were allotted to three treatments. Each treatment was further divided into four replicates of ten chickens each. They were fed 0.80% Thr and 1500 IU/kg vitamin A (control; NRC 1994 recommendation; T1), 0.87% Thr and 6250 IU/kg vitamin A (T2) and 0.94% thr and 11000 IU/kg vitamin A (T3) from the age of 1 to 14 days. Management and husbandry practices were in accordance with current standards. The villus height was significantly high (P<0.05) in T2 group with no significant effect on crypt depth. From the present study, it is clear that the higher level of Thr and vitamin A (T2) than the recommended level of NRC (1994) improved the villus height in growing broiler chicks.
