Abstract
The present study was carried out to study the effect of dietary incorporation of rice DDGS on performance of quails. Day old Japanese quails (n=180) were distributed randomly to five dietary groups each with three replicates of 12 birds each and were maintained under uniform management conditions. Experiment diets were prepared with incorporation of rice DDGS at 0% (T1: control), 5% (T2), 10% (T3), 15% (T4) and 20% (T5) levels by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Feed and water were provided adlibitum. The birds were housed in battery cages during the experiment period of 0-5 weeks.
Chemical analysis indicated that rice DDGS contained 45% CP, 6.71% CF, 7.93% EE, 0.07% calcium and 0.7% total phosphorus. Significantly (p<0.05) higher body weights were observed in birds fed with rice DDGS. The body weight gain was significantly increased (p<0.01) with increasing levels of rice DDGS. The overall feed intake was not affected by level of rice DDGS. Whereas, significantly better (p<0.01) FCR was reported at 20% level of rice DDGS inclusion.
Serum total protein was significantly (p<0.05) increased with increasing levels of rice DDGS. Whereas, Serum albumin, globulin and Albumin Globulin ratio were not affected by level of rice DDGS. But, serum total cholesterol was significantly decreased (p<0.05) with increasing levels of rice DDGS.
The carcass traits like live weight and carcass weight were significantly (p<0.05) increased with increasing levels of rice DDGS. On other hand, incorporation of rice DDGS from 0 to 20% in diet had no significant effect on dressing percentage, liver, heart, gizzard and giblet weights.
The meat quality parameter i.e., pH of meat of quails revealed that incorporation of rice DDGS up to 20% level had no effect.
The feed cost per kg gain was significantly (p<0.01) lowest in quails fed with 20% rice DDGS as compared with other treatment groups. The study indicated that the feed cost per kg gain was ₹ 106.75 (T1), 98.10 (T2), 95.01 (T3), 93.92 (T4) and 86.12 (T5).
It is concluded that rice DDGS can safely be incorporated up to 20% level in the diet without any adverse effect on performance of quails.
