MSc (Agriculture Animal Science), North-West University, Mahikeng Campus Legume leaves from lablab and cowpea can be incorporated in ruminants’ diets due to their high feeding value. They are rich in crude protein (CP), vitamins and minerals when compared to grasses that usually deteriorate during dry periods. The objective of this study was to determine the effect of supplementing legume leaves in maize straws on nutritive value, palatability indices and silage fermentation parameters. The study was conducted at the North-West University farm (Campus) and research farm (Molelwane), Mafikeng, North West province of South Africa. The study sites are located in the semi-arid region with geographical coordinates (25°49’22� S and 25°36’54� E) and (25°47’27� S and 25°37’18� E). Four legume species including Lablab purpureus and 3 Vigna unguiculata varieties (Dr Saunders, Betswit, and indigenous cowpea) were planted in monoculture in the experimental field, at 4 replications for every species. Maize (Zea mays) was planted in a monoculture. For the palatability experiment, each of five male boer goats was provided with four feeding troughs, with four different feeds (maize straws and 3 legumes (lablab and 2 cowpeas - Dr Saunders, and Betswit). Indigenous cowpea was excluded for palatability trial due to little quantity. For silage, the proportion of legume to maize was 20:80. Treatments were as follows, maize-lablab (ML) (20:80%), maize-indigenous cowpea (MI) (20:80%), maize-betswit (MB) (20:80%) and maize-Dr Saunders (MD) (20:80%), each with molasses (2%) to enhance fermentation. The controls were maize, without (negative control) or similarly treated with molasses (positive control). Molasses was diluted with distilled water at 1:2. The silages were opened after 45 days. The leaves and maize straw were analyzed for chemical composition and in vitro dry matter degradability (IVDMD) while silages were analyzed for chemical composition, fermentation characteristics, aerobic stability and IVDMD. All data were subjected to a one-way analysis of variance (SAS, 2010). The highest (P0.05) concentration of LA. The MM had the highest (P0.05). A higher (P |
