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.
