 Science Essay 代写:  生长育成猪的效率和胴体性状

Production and consumption of pork in Uganda has increased substantially in the recent decade. This increased demand for pork clearly offers opportunities to expand production. The liberalization of the economy makes it increasingly essential to become competitive in the market as this can contribute significantly to the profitability of the pig industry. However, in order for the pig farmers in Uganda to fully tap this market, there is a need to improve efficiency of production. Agro-industrial cereal by-products have the potential to improve pig productivity if properly utilized. These by-products are available in Uganda, however, information pertaining to their feeding value and effect on carcass characteristics in pigs still lacks. Although cereal processing by- products are fairy priced they are variable in quality hence posing a serious challenge in their use as pig feeds. Pond (1987), asserted that agro-industrial by-products such as maize cobs, distillery, milling by-products and other fibrous feeds could be used as energy sources for pigs. In Uganda, maize bran forms the bulk of ingredients used in livestock feeds but it is higher in price compared to other cereal by-products. Wheat bran has can be used in pig diet however it level of incorporation depends on the stage of growth of the animals. Therefore care is needed when using this by product for its high in fibre which impacts on its efficiency of utilization. Muir et al. (1992) reported good performance of pigs fed this by-product. The objective of the current study were to determine the effect of maize bran and wheat bran as dietary energy sources on growth, digestibility and carcass characteristics of growing pigs.
