| Abstrakt: | The present study was conducted with the objectives of determining the chemical composition and nutritional value of vegetable waste (VW) of households and the marketplace for their suitability as ruminant feed. The crude protein, total digestible nutrients and extent of rumen degradability of dry matter (DM) of VW of households were 140.0 g kg -1 , 0.668 and 0.855, respectively; while those of the marketplace were 169.0 g kg -1 , 0.633 and 0.80, respectively. The levels of chromium and lead in each respectively, was 13.27 and 1.53 ng kg -1 DM; and 31.01 and 5.71 ng kg -1 DM. The total aflatoxins in VW of households was 3.08 µg kg -1 DM, and undetectable in VW from the marketplace. Considering the chemical composition and safety parameters studied, VW could preliminary be considered as animal feed. The feeding of processed marketplace VW (VWP) at 275 g kg -1 DM of a diet or 0.76% of live weight (LW) to growing bulls, replacing 50% of a concentrate mixture as supplement to a Napier silage diet for a period of 34 days reduced the total DM intake (0.0276 vs 0.0343 LW) without any significant ( P > 0.05) changes in DM or protein digestibility. Blood urea levels (19.5 vs 23.67 mg dl -1 ), and serum creatinine levels (1.37 vs 1.08 mg dl -1 ) differed significantly ( P > 0.05) between the two groups but were within normal physiological ranges. Therefore, it may be concluded that the level of incorporation of VWP would be less than 50% replacement of the concentrate in the diet. Further research is required to determine optimum inclusion levels in ruminant diets. (© 2018 The Authors.) |
