Abstract:
The current investigation was carried out to study the effects of different rearing systems on cockerels on carcass traits and economics. The study was carried out on two hundred day old cockerel chicks procured from a local hatchery which were brooded for a period of two months. The cockerel chicks slaughtered at end of the experiment and the carcass weight was statistically (p < 0.05) significant and was heavier in the intensive system of rearing when compared to semi intensive system. The dressing percentage was higher in intensive (78.06±0.33) system than semi intensive system (77.40±0.65) of rearing cockerel. After two months the cockerel chicks raised in intensive system showed 1.0% mortality in first fortnight in both intensive and semi intensive system with the livability percentage of 99%. The economics was calculated on feed cost as the other manage mental cost remained same for both the groups Revenue from sale of chicks was higher in intensive system (Rs 133.40/-) Benefit cost ratio of 1.27 and 1.00 was observed respectively in semi intensive and intensive system of rearing cockerels. The reason for increased profit Rs/ chick and B:C ratio could be due to 50% of the feed was reduced in semi intensive cockerels as they had an option of feeding on scavenging feed resources base for the duration of four hours per day and also the scavenging feed resources might have more influenced positively on organoleptic characteristic as per consumer preference.
