Abstract
The objectives of this study were to evaluate the effect of pollard utilization and
addition of critical amino acid (methionine, lysine, tryptophan and threonine) on the
growth performance of layer. Three hundred and ninety nine day old chicks of
Lehman layer strain were used in the experiments. The birds were allocated into
treatments of pollard level consisting of 0, 10, 20 and 30% of the diets and addition
of critical amino acid 0,5 and l time of amino acid contents in the control diets (P.0,
P.l, P.2, P.3, P.4, P.5 and P.6). The iso-protein and iso-calory diets were made and
formulated according to NRC (1994). The result showed that utilization and addition
of critical amino acid were significantly affected (P<0.05) body weight (353,50,
384,20, 411,40 396,49, 378,94, 353,50 and 330,70g), feed consumption (ll71,30,
1185,00, 1073,31, 1210,35, 1071,47, 1195,47 and l25l,04g) and feed conversion
(3,68, 3,41, 2,84, 3,36, 3,09, 3,77 and 4,21) but not the liver (9,34 9,47 9,83 8,73
9,04 8,57 and 8,78g) and bile (0,64, 0,65, 0,63, 0,78, 0,60, 0,66 and 0,64g) weights, also on trygliceride (84.21, 63.16, 70.18, 45.62, 56.14 and 52.63mg/dl) and cholesterol of blood plasma (114.67, 93.33, 88.00, 104.00, 93.33, 82.67 and 112.00 mg/dl).
