Abstract

A 16 week feeding trial was conducted to evaluate the effects of replacement of soybean meal (SM) by extracted cottonseed meal (CSM) on laying performance and haemoglobin levels in practical diets for breeder Japanese quail (Coturnix coturnix japonica). One hundred ninety two quails (6 weeks old) were divided randomly into eight groups. The diets were isocaloric containing 2,900 kcal/kg of ME and isonitrogenous (% 20 crude protein) as fed basis. SM was replaced by 0, 2.5, 5.0, 7.5, 10.0, 12.5, 15.0 and 17.5% of CSM, respectively. Average egg production (quail day, %; quail house, %), egg weight (g), daily feed intake (g/bird), feed efficiency ratio (g feed/g egg) data indicated no significant differences among the treatments; while, blood haemoglobin levels (% g Hb) of 7th (15.0% CSM) and 8th (17.5% CSM) group were lower than the control (0% CSM) diet (p < 0.05). This experiment indicated that 17.5% CSM could replace SM (providing 44% of SM protein) in practical diets of breeder Japanese quails without any significant impairment on laying performance.
