作者： nani g.das Khan S.Huque Sardar M.Amanullah Harinder P.S.Makkar Bangladesh Livestock Research Institute(BLRI) Environment and ILM Specialist Department of Livestock ServicesKrishi Khamar Sarak Livestock Production Systems Branch Animal Production and Health Division Institute for Animal Production in the Tropics and Subtropics(480B) University of Hohenheim

The study was conducted with the objectives to quantify year round availability of different vegetables waste(VW) in a wholesale market and to determine the inclusion level of a processed VW(VWP) in the diets of bulls. The daily VW biomass availability at Kawran bazaar, Dhaka, Bangladesh was quantified by weighing the vegetable supply and their wastes by visiting 2 days in a week. Concurrently, VW of cucumber, bitter gourd, spotted gourd, brinjal, pumpkin, potato, tomato, ladies finger, and snake gourd representing 0.21, 0.18, 0.17, 0.16, 0.09, 0.07, 0.06, 0.03, and 0.02 as fresh fractions, respectively were blended, dried and stored while adding rice polish and common salt at 200 and 20 g/kg DM, respectively;it was tested in bulls as an ingredient of concentrate mixture. Four dietary groups, each of 6 bulls, with initial average live weight(LW) of 85.47 ± 17 kg, were fed fresh german grass(Echinochloa polystachya)ad libitum supplemented with 4 different concentrates containing 0, 10%, 20% and 30% VWP at the rate of1% of LW for 89 days. The availability of VW biomass of the market was 42.51 t/d and recycling of them as feed, instead of using landfills, might reduce annual methane emission by 0.43 gg. The inclusion of VWP in the diet up to 9.7% of DM, or 0.30% of LW of bulls showed no significant effect on the DM intake,digestibility, growth performance and health status of bulls. The dietary DM intake represented 3.10%,3.09%, 3.20% and 3.14% of LW resulting in daily gain of 302, 300, 312 and 344 g, respectively. The digestibility of DM of diets was 56.9%, 62.8%, 62.8% and 63.4%, respectively. It was concluded that VWP may be included at a level of 9.7% of the diet(DM basis) or 0.30% of LW of bulls.
