Description A growth study was conducted in native ram lambs for 150 days to investigate the effect of feeding sorghum stover based complete rations at 50:50 roughage to concentrate ratio with varying levels of DDGS in concentrate mixture viz. T1 (0% DDGS), T2 (10% DDGS), T3 (20% DDGS) and T4 (30% DDGS) to find out the optimumlevel of inclusion of DDGS in concentrate along with sorghum stover based complete rations on growth performance, nutrient utilization and carcass characteristics.
ADG was increased progressively but not significantly (P>0.05) as the level of DDGS in concentrate supplementation increased in the rations. The increase in body weights was 5.67% in T3 ration followed by 1.28% in T4, 0.51% in T2 when compared to T1 ration (control). There was no significant difference in FCR for four sorghum stover based complete rations containing varying levels of DDGS and the feed efficiency was better in T3 (9.54%) ration followed by T4 (3.24%) when compare to control. The cost (Rs.) per kg live weight gain was comparatively low in T3 ration, and followed by T4, T2 and control (T1), respectively.
No significant difference was observed among T1, T2, T3 and T4 experimental complete rations in the digestibility coefficient of DM, OM, CP, EE, CF and NFE values. The digestibility values of T2, T3 and T4 complete rations were comparable to
T1). The apparent digestibility coefficient of NDF, ADF, hemicellulose and cellulose was not significant among four experimental complete rations.
No significance difference was observed among four experimental rations in the percent of DCP and TDN.
The N balance and N absorbed (g/d) were not significantly (P>0.05) different among four experimental rations. But higher nitrogen balance was observed in T3 ration followed by T4, T2 and T1 rations and T2, T3 and T4 values were comparable with T1.
DCP intake (g/d or g/kg w0.75) was not significantly (P>0.05) different among T1, T2, T3 and T4 rations. TDN intake (g/d or g/kg w0.75) was also not significantly different (P>0.05) among the sorghum stover based complete rations.
No significant difference (P>0.05) was observed among T1, T2, T3 and T4 experimental complete rations on the pre slaughter weight, empty body weights and hot carcass weights of native ram lambs and were comparable with T1 ration (control).
There was no significant difference in dressing percentage either on live weight basis or empty weight basis among four experimental rations.There was no significant (P>0.05) difference in whole sale cuts, edible, non-edible portion and ratio of edible and non-edible portions among the four experimental complete rations fed to native ram lambs.
There was no significant difference (P>0.05) observed in yield of visceral organs, meat, bone, fat and meat bone ratio among four experimental rations. The T2, T3 and T4 complete rations were comparable with T1 ration (control). The DDGS inclusion at various levels in the concentrate of sorghum stover based complete rations fed to ram lambs did not show any adverse effect on carcass characteristics.
DDGS was the best quality protein and energy source and it was readily available in all seasons and it can be incorporated at varying levels (10, 20 and 30 percent) in concentrate mixture and can also be incorporated in sorghum stover based complete rations for optimum growth with better feed efficiency and performance in growing native ram lambs. Varying levels of DDGS in concentrate with sorghum stover in complete rations did not affect the performance, nutrient digestibility and carcass characteristics. Based on the results of the present study, it may be concluded that DDGS, a potential agro-industrial by product which was economical compared to the traditional feed ingredients, could be included at 30% level in the concentrate of sorghum stover based complete rations without any adverse effect.
