Manure characteristics of small ruminants fed agro by-products in the guinea savannah agro-ecological zone of Ghana

A 90 day study on evaluating quantity and quality of manure from small ruminants in the Guinea Savannah agro-ecological zone of Ghana was conducted. 36 goats and 36 sheep were random­ly allotted to three dietary treatments - Basal diets of maize stover, cassava and yam peels as Treatment one (T1), T1 supplemented with cowpea residues as Treatment two (T2) and T1 supplemented with groundnut residues as Treatment three (T3) in a randomized complete block design. Feed composition and intake and manure characteristics were assessed and data ana­lyzed statistically using Generalized Linear Model procedures of SAS at 5% significance level. The Chemical composition of feed resources ranged from 3.2-17.3% crude protein, 82-97.2% organic matter and 2.8-18% ash. Total feed intake ranged from 519.55-659.72 g/day and 331.84-420.17 g/day for sheep and goats respectively. Sheep manure weighed 319.17-423.33 g/day and contained 20.74-29.01% carbon, 1.87-2.32% nitrogen, 0.77-3.00 potassium, 9.52-26.50% ash, 0.44-0.77 pH and C:N ratio of 10.98-15.53. Goat manure weighed 178.67-216.17 g/day with 19.58-30.61%, 1.56-2.21% nitrogen, 0.82-2.33% potassium, 10.75-19.80% ash, 0.37-1.47 pH and C:N ratio of 9.49-19.92. Results indicated that manure from small ruminants could serve as alternative source of fertilizer in Ghana since its characteristics compare well with chemical fertilizers. Keywords: sheep; goats; feed resources; manure; fertilizers
