Abstract

The objective of this study was to determine the effect of birds density (12, 14 and 16 birds/ m2), the level of metabolizable energy (3000, 3100, and 3200 k. cal./ kg. feed) and crude protein (19 and 21% on broiler chicken performance by using 1512 birds aged 28 days.
The results revealed that there was a significant difference in weight gain in the 5 and 6treatments compared with other treatments, while the treatments 1, 2, 3, 4, 5, 6 and 8 revealed a significant difference in feed consumption. The feed conversion was well in hanced within the birds of treatment 5, 6, 11 and 12. The weight gain significantly decreased with the increase of the bird's density. The bird's density of 12 birds/ m2 exhibits a significant increase in weight gain (1218 gm.) with feed consumption (2919 gm.) and feed conversion (2.4).
The birds feed diet containing 3200 k.cal significantly weight gain (1196 gm.) with a feed conversion (2.38). In contrast, there was a significant difference in feed consumption in birds treated with 3000 and 3200 k.cal.
The birds fed with 21% crude protein exhibited a significant increase in weight gain and feed consumption compared with 19% crude protein.
It may be conclude that the rearing of birds in a density more than 12 birds/ m2 has not economic importance unless some other factors are available such as good management, suitable feeders, waters and good atmosphere condition.
