Abstract
Twenty Red Sokoto Goats (aged between 10 and 19 months and
weighing an average of 12.00kg), were randomly assigned to five dietary
treatments in a conpletely randomized design, to determine the effect of two
types of protein supplements (cotton seed cake and blood meal) and their
various combination on feed intake, growth and nutrient utilization by goats fed
basal diet of fresh wooly finger grass (Digitaria smutsii). The dietary treatment
groups were cotton seed cake (CC) only blood meal (BM) only and combination
ratios of cotton seed cake and bloods meal (CB) 1:1, 2:1 and 1:2. The growth
trial which lasted 91 days showed that total dry matter intake (DMT) (g/hd),
crude protein intake (CPI) (g/hd) and feed conversion ratio (FCR) were similar
across treatments. Significant (P<o.05) difference in daily weight gain (g/hd) was
only noticed between the goats fed ratio 1:2 and BM. The result of the
metabolism trial showed that there were no significant (P>0.05) differences in the
apparent digestibility of dry matter (DMD), organic matter (OMD), neutral
detergent fibre (NDFD) and acid detergent fibre (ADFD). Crude protein
digestibility (CPD) were significantly (P<0.05) higher in the goats fed CC only and
BM only than in the goats fed the mixtures. Faecal nitrogen in the goats fed CB
2:1 was significantly (P<0.05) higher than in those fed BM only. There were
significant (P<0.05) treatment effect on the values of volatile fatty acids (VFA),
five hours after feeding and those of rumen pH. However no treatment effect
(P>0.05) was noticed on rumen ammonia values. In conclusion, the results of the
studies indicate that feeding cotton seed cake and blood meal in concentrate in
ratio 1:2 may enhance the growth performance of goats.
