Abstract

Tea waste is by-product of tea manufacturer that is potential as an alternative of protein source. Twenty male cross-breed weanling rabbits were used to investigate the optimum utilization of tea waste in ration of rabbit. Completely randomized design was used with four treatments and five replications. The levels of tea waste in pellet rations as the treatment consisted of 0% (AT0), 10% (AT10), 20% (AT20), and 30% (AT30) of dry matter. The dry matter intake, average daily gain (AVG), ration conversion, mortality, and economical value were measured in this experiment. The result showed that the treatments did not significantly affect dry matter intake, average daily gain, and ration conversion. The mortality was 0 percent and the profit increased in ration containing tea waste. It was concluded that tea waste could support good performance of the rabbits and it could be used as an alternative of protein sources until 30% in ration. Key words: rabbit, tea waste, protein sources

Abstract

Twenty male cross-breed weanling rabbits were used to study the effect of urea or DL-methionine addition in sweet potatoes biomass complete diets. Completely randomized design was used in this experiment with four treatments and five replications. The treatments consisted of A (comercial diet); B (sweet potatoes biomass diet); BU (B + 0.5% urea) and BM (B + 0.5% DL-methionine). The dry matter intake, average daily gain (AVG), feed conversion ratio, dry matter and protein digestibility and nitrogen retention were measured in this experiment. The result showed that the treatments did not significantly affect dry matter intake and feed conversion ratio, digestibility of dry matter and protein, but supplementation of DL-methionine significantly affected average daily gain and nitrogen retention (P < 0.05). It was concluded that urea or DL-methionine supplementation in sweet potatoes biomass diets could support good performance of rabbits and it could be used as an alternative source of feed for rabbits. Key words : rabbit, sweet potatoes, urea, DL-methionine, performance
