Growth Performance, Nutrient Utilization and Carcass Characteristics of Rabbits Fed Malted Sorghum Sprout (MSP) Based Diets

摘要

Twenty four hybrid weaner rabbits of both sexes were used to evaluate the usefulness of malted sorghum sprout. The rabbits were randomly allotted to four dietary groups of 6 rabbits and three replicates of 2 rabbits each. The MSP was incorporated into the diet at 0, 10, 20 and 30% levels. The experiment lasted for 56 days. Feed and water were supplied ad libitum. The performance characteristics, nutrient utilization, carcass characteristics and economics of production were measures of response. The result showed that, the final live weight and daily weight gain of rabbits on 0 and 20% MSP diets were highest (p<0.05). The daily feed intake of rabbits on MSP diets were significantly (p<0.05) lower than those on 0% MSP. The dry matter, crude protein and crude fibre digestibility significantly declined (p<0.05) as the level of MSP inclusion increases. Energy intake and energy retained followed a similar trend. Carcass weight, liver, kidney and heart weights were significantly (p<0.05) influenced by the dietary treatment. Less cost was incurred in producing a kilogram of rabbit when fed 20 and 30% MSP levels. 20% level of inclusion in rabbit diet could be of benefit in terms cost reduction and better growth.
