EFFECT OF SUGARCANE BY-PRODUCT BASED COMPLETE RATIONS ON GROWTH AND CARCASS CHARACTERISTICS IN BUFFALO BULL CALVES

Abstract

Six rations comprising of five complete rations and one conventional ration (containing
chopped hybrid Napier and concentrate mixture) were formulated by using sugarcane byproducts
and other crop residues and balanced concentrate mixture in the mash form.
These rations were compared by feeding to 24 Murrah buffalo bull calves for a period of 167
days using Randomized Block Design to study the effect of processing of complete diet on
growth, nutrient utilization and carcass characteristics. Highest ADG (610.0g.) recorded in
buffalo bull calves fed on complete ration-II (Sugarcane tops, maize stover and balanced
concentrate mixture) when compared among the complete rations and control. The cost of
control ration per kg live wt.gain was Rs.41.14.The cost of complete ration per kg live weight
gain was higher in control than complete rations though insignificantly different. The cost of
complete ration per kg live weight gain was reduced by Rs.3.11, 8.69, 8.60, 10.92 and 8.10
for complete rations-I, II, III, IV and VI, respectively, when compared to control diet. The
dressing percentage on live weight was significantly (P<0.05) lower in bull calves fed on
complete rations than those fed on control ration. The dressing percentage and proportions
of the wholesale cuts were within the normal range. These results indicated that the
sugarcane by-products and other crop residues can be incorporated in the complete rations
in growing bull calves without any adverse effects. Further, utilization of agro-industrial byproducts
for animal production can be utilized effectively to bridge the gap of roughage
shortage in this country.
