Effect of different feeding program at first day on performanceand economic index of broiler chickens

الملخص EN

A total of 132 one day old Ross (308) broiler chickens were used to determine the effect of four treatments (feed program) on broiler performance and economic index.

At delivery the chicks were weighted.

As well as, the body weight, weight gain, feed intake, feed conversion ratio was recorded at day 14, 21, 28, 35 and 42.

Economic index was recorded at 42.

Four treatments includes: feeding immediately after delivery in the hatchery and continue to the farm (T1); fasting for 12 hours after hatch with access to water (T2); fasting for 12 hours with access to water containing 5% sugar followed by feeding the diet (T3); or feeding a diet immediately at the farm (T4).

Interaction between treatments and different periods, were significantly (p<0.05) effected on body weight, although, the effect of treatments at each period did not significant.

Overall of body weight/ period was significantly (p<0.05) higher at day 42 followed by the least periods.

Significant (p<0.05) effect of interaction between treatments with periods, treatments and periods were observed in feed intake and weight gain.

Feed conversion ratio did not significantly affected by different periods.

Economic index did not significantly affected by different treatments.

Values of economic index were numerally influenced of: body weight, body weight gain, feed intake, viability% and feed conversion ratio.
