Abstract

The effects of the fungus, Trichoderma harzanium, treated cassava waste on milk quantity and quality were investigated in a completely randomized design model with twelve lactating West African dwarf does. Goats were fed the experimental diets containing O (A), 20 (B), 30 (C) and 40% (D) Trichoderma treated cassava waste during a 13 week lactation trial. The results revealed significant differences in milk quantity and quality. The highest milk yield was recorded for diet D followed closely by diets C, B and A in that order. Inclusion of fungus treated cassava waste resulted in significant increasing milk fat, protein, solids not fat (SNF), and total solids. While the inclusion had little effect on milk pH and specific gravity. The yield of 40% fat corrected milk (FCM) and gross efficiency of milk increased significantly (P < 0.05) by the addition of fungus treated cassava waste in the diet. In conclusion, the addition ofTrichoderma treated cassava waste was beneficial to lactating West African dwarf goats.
