Abstract
The study was conducted to evaluate the effects of treated rice husk as a replacement for wheat
bran on the Carcass characteristics of West African Dwarf (WAD) goats. Twenty (20) WAD goats
were subjected to five dietary treatments in a completely randomized design with 4 animals per
treatment. The treatments were: 0% RH (T1), 25% RH (T2), 50% RH (T3), 75% RH (T4) and
100% RH (T5)in replacement for wheat bran. The animals were fed their respective diets at 5% of
their body weight for 90 days. The results showed that T2 and T1 were relatively high in crude
protein, low in crude fiber, moderate in crude fat and high in carbohydrate. They equally had the
lowest values of ADF, ADL and NDF among the treatments. Live weight, slaughter weight, carcass
weight and dressing percentage were all significantly (P<0.05) influenced by the dietary
treatments. The values were highest in goat fed T1, followed by those on T2, then T3 and then by
those on T4, while the goats fed T5 had the least values for live weight, slaughter weight, carcass
weight and dressing percentage, respectively. The carcass yield parameters were observed to
decrease as the inclusion level of treated rice husk increases. All the prime cuts were significantly
(P<0.05) influenced by the dietary treatments. The relative weight of all the prime cuts decreased
as the inclusion level of treated rice husk increases. Among the goats given the treated rice husk,
T2 and T3 appeared to have more carcass characteristics. It is concluded that diet with 25% (T2)
and 50% (T3) rice husk replacement level gave more carcass characteristics as carcass weight,
dressing percentage, organ weight and prime cuts recorded more improvement. Thus, treated rice
husk as a replacement for wheat bran at lower inclusion level (up to 50% at 5% body weight) is
recommended to give appreciable performance on WAD goat.
