Effect of Replacing Oil Seed Cakes with Rice Dried Distiller's Grains with Solubles in Concentrate Mixture on Growth and Nutrient Utilization in Murrah Heifers

The present study was carried out to evaluate the effect of supplementation of concentrate at different levels to sweet sorghum bagasse leaf residue (SSBLR) silage on nutrient utilization in growing lambs in a metabolism trial conducted after 120days of feeding. Sixteen growing Nellore ram lambs (18.3±0.8) were randomly allotted to 4 dietary groups (4 in each group) and were inducted into metabolic cages five days prior to collection for acclimatization followed by a seven day collection period. The four dietary groups were SSBLR silage fed ad libitum and supplemented with concentrate mixture (CP 17% and ME 2.53 Mcal/kg DM) at 0.0 (R-I), 0.75 (R-II), 1.0 (R-III) and 1.25 (R-IV) per cent of their live Weight. Significantly (P<0.01) higher total DMI (g/kg w0.75) was noticed in concentrate supplemented groups. The organic matter, crude protein and nitrogen free extract digestibility was significantly (P<0.05) higher in lambs fed R-IV ration than those fed R-I ration. No significant difference in the digestibility of dry matter, ether extract and cell wall constituents was observed among the rations. The digestible crude protein (%) (P<0.01) and metabolizable energy (Mcal/kg) values increased (P>0.0) with increase in level of concentrate in the diet. Negative and lower (P<0.01) nitrogen balance (g/d) was noticed in R-I ration. The N balance linearly increased with increase in level of concentrate supplementation. The study indicated feeding of sole SSBLR silage couldn't meet the nutrient requirements and Supplementation of concentrate mixture (0.75-1.25%) to SSBLR silage improved the nutrient digestibility and nitrogen balance in growing lambs.

Oil Seed Cakes

A trial was conducted to evaluate the effects of combination of soybean meal (SBN), mustard oilcake (MOC), sesame oilcake (SOC) and linseed oilcake (LOC) as alternative for dietary fish meal (FM) protein for Labeo rohita fingerling for a period of 56 days. Six experimental diets were formulated by replacing 30, 50, 60, 70 and 100% (2 diets) of the total dietary fish meal protein by the combination of FM, SBM, MOC, SOC, and LOC. The combinations of the protein sources were as diet 1 (FM 100%), diet 2 (FM:SBM:MOC::70:15:15), diet 3 (FM:SBM:SOC:LOC::50:20:20:10), diet 4 (FM:SBM:SOC:LOC::40:20:20:20), diet 5 (FM:SBM:SOC:LOC::25:30:15:30), diet 6 (SBM:MOC:SOC:LOC::25:25:25:25) and diet 7 (SBM:SOC:LOC::40:30:30). The performances of these six test diets were compared with the diet 1 (control). All diets were iso-nitrogenous containing about 30% protein. The growth trial was conducted in a flow through system under laboratory condition with three replications for each treatment. On the basis of the growth response, food conversion ratio (FCR), protein efficiency ratio (PER) diet 7 showed better performance followed by diet 1, diet 2, diet 5, diet 3, diet 4 and diet 6 respectively but those were not significantly different (P>0.05). The diet 6 produced the lowest performance. The apparent protein digestibility (APD) values for all the experimental diets were very nearer but significantly different (P0.05) in diets even from control one which were formulated to evaluate the effects of combination of low cost oil seed cakes as dietary protein source for Labeo rohita fingerling. Hence, it might be concluded that from the economic point of view, that all the low cost oil seed cakes which are locally available can be used in combination form as the alternative protein source for the feed of Labeo rohita.
