Abstract
An experiment of 90 days duration was carried out on fourteen adult sheep to study the effect of wheat straw based total mixed ration on their digestibility and nutrient utilization. The study was conducted in two phases. In phase I, In vitro DMD (Dry Matter Digestibility) and OMD (Organic Matter Digestibility) of TMR (Total Mixed Ration) with different roughage (wheat straw) concentrate (Amuldan) ratio (40:60, 50:50 and 60:40) were studied. The highest in vitro DMD (52.01%) and OMD (62.79%) were observed at 50:50 (roughage:concentrate) ratio in TMR. Hence, it was further evaluated by in vivo study. The sheep under control group (T1) were fed wheat straw and concentrate separately where as sheep under treatment group (T1) were fed wheat straw based total mixed ration in the ratio (50:50). Quantity of feed offered was adjusted at weekly interval according to change in body weight of sheep. Individual feeding of all the sheep was carried out during the study period. The nutrient requirements of sheep in term of DCP and TDN were met as per ICAR (1998) feeding standards.
