Sažetak
An experiment was conducted to study the effects of dietary energy and protein
dilution and time of feed replacement from starter to grower on performance of
broilers with a 2×3 factorial arrangement in a completely randomized design with 480
day-old broilers from 1-42 day of age. Experimental treatments were 5% energy and
protein diluted diets and starter diet was fed to 7, 14 or 21 days and finisher diet was
fed beginning at 35 days. Grower diet was fed for variable times depending upon
termination of feeding starter diet and initiation of finisher diet.
Dilution of both energy and protein had no (P>0.05) significant effect on chicks
performance, but significantly (P<0.05) increased breast meat yield. Reduction the
time of feeding starter diet did not show any significant effects on bird's performance.
From 1-42 days of age, the interaction between dilution of both energy and protein
and changing time from starter to grower diets on body weight and feed intake was
not significant(P<0.05). The results from this study suggest that diluting of both
energy and protein up to 5% from 1-42 days of age and decreasing the time of starter
diet had no adverse effect on broiler chickens performance and it may be beneficial
economically.
