ABSTRACTThis study was conducted to determine the growth performance, organ weights, and selected blood parameters of replacement laying pullets (development phase) fed increasing levels of wheat bran (WB). A total of 240 70-d-old White Leghorn pullets (Hybrid L33) were evaluated for seven weeks. Birds were assigned to three dietary treatments according to a completely randomized design. Treatments consisted of diets containing 100 (T1), 150 (T2), or 200 g/kg (T3) of WB in partial replacement of corn, with 10 replicates per treatment of eight birds per replicate. Birds fed T2 presented higher body weight (p<0.05) compared with T1 and T3 (1112.52 to 1163.35 g). Also, T2 birds presented higher methionine plus cystine intake relative to T1 (0.38 to 0.40... |

ABSTRACT The aim of this study was to determine the effects of dietary supplementation with red algae powder (Chondrus crispus) on the growth performance, carcass traits, lymphoid organ weights and intestinal pH y in broiler chickens. A total of 300 1-day-old B34 line male broiler chickens were randomly allotted to three treatments, four replicates per treatment and 25 birds per replicate. The experimental treatments consisted of a basal diet (T0) and dietary supplementation of 0.30 (T2) and 0.40% (T2) red algae powder. Body weight at 1, 21 and 32 days did not show significant differences (p>0.05) among treatments. At 21 days, T1decreased (p<0.05) the feed intake and feed conversion ratio. However, from 22 to up to 32 days, these productive... |
