    The utilization of silk cotton seed (Ceiba patandra) as a substitute for full fat soyabeans was evaluated using 120 Anak broiler chickens during 8 week feeding trails in which silk cotton seed (toasted, TSCS and untoasted, USCS) was used to replace soyabean at 0%(T1), 50%TSC (T2), 50%USCS (T3), 100%TSCS (T4) and 100% USCS(T5).Data were collected on average feed consumption, body weight gain (BWG), feed conversion ratio (FCR) and performance index. The results obtained showed treatment effect on feed intake and weight gain was significant (P<0.05). However, the highest feed intake and weight gain (880.68 g and, 429.65g) respectively was recorded for T1 (control). T 2 showed the best replacement potentials for soyabeans in terms of feed intake (676.16 g ) and BWG (449.56 g). Similarly, mean feed conversion ratio and performance index were significantly (P<0.05) different between treatment groups. From the results obtained in this study, it could be concluded that 50% replacement of soyabeans with toasted silk cotton seed (TSCS) is a desirable substitute for soyabean in the diets of broilers.

    Performance of West African Dwarf (WAD) Goats Fed Urea Treated Maize Offal as Supplement to Natural Herbage
    (Department of Animal science,Nasarawa State University Keffi, 2010-12-01) Ari, Maikano Mohammed; Barde, R.E.; Aya, V.E.; Musa, M.; Yakubu, A.
    West African Dwarf (WAD) goats grazing natural herbage were supplemented with different levels of urea treated maize offal (UMO) to determine their performance. The maize offal were treated at 0% UMO, 4% UMO, 6% UMO and 8% UMO representing 0, 4, 6 and 8% of urea respectively. Naturally grazing twenty WAD bucks aged between 7 and 9 months weighing 8.7±1.5kg were randomly allocated to five supplementary diets (0% UMO, 4% UMO, 6% UMO and 8% UMO) in a completely randomized design lasting 84 days to determine the effect of the supplementation. Significant (P<0.05) mean weight gained of 5.30kg was recorded for goats on 4%UMO; Similarly, lowest (P<0.05) feed conversion ratio of 7.28 was obtained for 4%UMO and better benefit of N 3,170 per live weight gain was recorded for goats on the same 4% urea treatment. Though the different levels of urea treatment of maize offal recorded significant (P<0.05) increase in blood urea, they were below the toxic concentration level of10mg per liter; and superior performance was recorded for WAD goats fed 4% of UMO supplement.
