تأثير الكثافة على بعض الصفات الإنتاجية لفروج اللحم

الملخص EN

The experiment was conducted to determine the effect of different levels of density on body weight, weight gain, production of live weight /m2, mortality percentage, feed intake, feed conversion rates, dressing percentage and percentage of evisceration of edible.

A total of 360 day old broiler was randomly assigned to the four treatments (12, 14, 16, and 18 broiler per square meter) with three replicates per treatment.

There were no significant differences among treatments for the parameters studied: body weight, weight gain, and mortality percentage at 4 and 6 weeks of age.

Whereas the total live weight yield / unit area increased with density increase.

The differences between treatments 12, 14 broiler /m2, with treatments 16 and 18 broiler /m2 at 4 and 6 weeks of age respectively were significantly (P<0.05).

The differences of dressing percentage and the percentage of gizzard and spleen were significant, while differences of the percentage of liver and heart were not significant.

The results indicated that, there were significant effects (P<0.05) in densities on feed consumption and feed conversion at 4 and 6 weeks of age.
