A 2 x 6x 3 replicates per treatment factorial experiment in Completely Randomized Design was conducted to compare the performance of two broiler strains (Corbett-Strain A and Ross-Strain B) when subjected to six feeding regimes: (1) CBM (to 10d),BSM (to 35d), BFM; (2) CBM (to 14d), BSM (to 35d),BEM ; (3) CBM (to 10d), BSM (to 28d), BFM; (4) CBM (to 14d), BSM (to 28d), BFM; (5) BSM (to 35d), BFM; and (6) straight BSM up to 45 days.
Results showed significant body weight differences(P < 0.01) ‘between strains at week 0 but non-significant differences (P>0.05) at week six. Body weight was Similar (P > 0.05) between feeding regimes throughout the six-week period.
Feed consumption of Strain A was lowest (P < 0.05) in Regime 5 while that of Strain B was lowest (P < 0.05) in Regime 6, resulting in a significant (P < 0.01) strain x feeding regime interaction. Since feed conversion efficiency was based on feed consumption, this followed a similar trend.
Dressing percentage was not influenced (P »> 0.05)by strain. Sex x feeding regime interaction (P < 0.05) indicated that males had higher dressing percentage in Regime 1 while females, in Regime 4.
The relative weights of the gizzard (P < 0.01), liver (P < 0.05), heart (P < 0.05) and intestines (P < 0.01) were higher in Strain A than in Strain B. There was a significant (P < 0.05) sex x feeding regime interaction in gizzard weight.
The relative abdominal fat pad and feather weight was not affected (P > 0.05) by strain, sex nor feeding regime. Mortality was very low and occurred only in Strain A in weeks O and 5.
Strain A was more profitable in Regime 5 while Strain B was more profitable in Regime 6. Overall, Strain A was more profitable than Strain B.
