Abstract
The study was aimed at evaluating the liveweight performance of sheep and goats and the
quality of stored fodder and manure at Atebubu and Amantin in the Brong-Ahafo Region of
Ghana. Six farmers (three males and three females) were selected from each Community
with each farmer providing six animals (three sheep and three goats). Feed resources used
in the study areas contained 3.2-17.3% crude protein, 82-97.2% organic matter and 2.8-18% ash contents. The dietary treatments were Treatment 1 (basal diets of maize stover,
cassava and yam peels), Treatment 2 (supplementation of treatment 1 with cowpea
residues) and Treatment 3 (supplementation of treatment 1 with groundnut residues) in a
completely randomized block design. Nutrient composition of the feed materials used in
Atebubu ranged from 89.43-91.2 % (OM), 84.22-88.50 % (DM), 6.41-11.58 % (CP), 8.8-9.57 % (Ash) with that of Amantin having 83.5-89.40 % (DM), 85.62-88.97% (OM), 5.32-10.27% (CP) and 11.04-12.38% (Ash). Total feed intake (TFI) ranged from 519.55-659.72g/day and 331.84-420.17 g/day for sheep and goats respectively, with their
corresponding weight gain of 14.96-25.74g/day and 8.52-18.89g/day. Feed conversion ratio
(FCR) ranged from 22.08-64.24 and 18.38-53.45 for sheep and goats respectively. Samples
of groundnut and cowpea residues in open and closed storage systems, taken at 1, 4, 8, 12,
14, 20, 24 and 28 weeks, showed an insignificant decline in crude protein content with
storage time. Manure produced by sheep weighed 319.17-423.33g/day and contained
20.74-29.01% C, 1.87-2.32% N, 0.77-3.00 K, 9.52-26.50% Ash with a pH of 0.44-0.77 and
a C:N ratio of 10.98-15.53 while that of goats weighed 178.67-216.17g/day with 19.58-30.61% C ,1.56-2.21% N, 0.82-8.33% K, 10.75-19.80% Ash with a pH of 0.37-1.47 and a
C:N ratio of 9.49-19.92. The results from this trial suggest that locally available feed
resources can significantly contribute to meeting the nutrient requirements of ruminants.
