Abstract

Abstract: An experiment was conducted to determine the effect of the rearing system and feed on early growth performance of crossing chicken (male local chicken x female Isa Brown final stock laying chicken). One hundred 1-d-old chicks were randomly assigned to 2 factor treatments, the first factor was rearing cages (indoor and outdoor access) and the second factor was feed ration (20% and 17% crude protein). In the indoor treatment, the chickens were housed in floor pens (5 birds/m2). In the outdoor access treatment, the chickens were housed in a similar indoor house; in addition, they also had an outdoor grass paddock (5 birds/m2). All birds were provided ad libitum water and were raised from 14 to 35 days of age. The results showed that early production performance (average daily gain, feed intake and feed conversion ratio) were different among treatment (P>0.05) at 28 and 35 days. The early growth performance of crossing chicken between Bangkok chicken and layer chicken have good performance in the indoor or outdoor cages with nutritional content of 20% crude protein and energy metabolize 2900 kcal/kg
