Protein requirement of Japanese quail (coturnix corturnix japonica) chicks in Nigeria

A feeding trial was conducted to determine the effect of varying dietary levels protein on performance Japanese quail chicks. Six iso-caloric (2953-3078 kcal/kg, ME) diets were formulated contain crude (CP) at 18, 20, 22, 24, 26 and 28% levels, respectively. Each treatment replicated three times with sixty (60) chicks per replicate. total 1080 day-old unsexed used for study distributed using completely randomized design. The experiment lasted 42 days during which data collected. Feed water provided ad libitum throughout experimental period. intake, weight gain, feed conversion ratio intake differ significantly (P<0.05) due treatments. Final live cost gain not (P>0.05) different across Age first egg average eggs point lay differed haematological parameters (Total protein, haemoglobin, albumen red blood cell) affected by levels. Carcass weight, dressing percentage, prime cuts major organs expressed as percentage It concluded that required up 26% level optimum performance.
