 Science Essay 代写:  生长育成猪的效率和胴体性状

近十年乌干达猪肉生产和消费量大幅增加。这增加对猪肉的需求显然提供了扩大生产的机会。经济的自由化使它变得越来越重要,在市场上的竞争力,这可以有助于养猪业的盈利能力显着。然而,为了在乌干达的养猪户充分挖掘这一市场,有必要提高生产效率。农产品工业谷物副产品有可能提高猪的生产力,如果正确利用。这些副产品在乌干达,但是,有关他们的饲养价值和对猪的胴体特性的信息仍然缺乏。虽然谷物加工的-产品是童话定价,他们是可变的质量,因此构成了一个严重的挑战,在他们的使用作为猪饲料。池(1987),主张工农业副产品如玉米棒子、酒厂、加工副产品和其他纤维饲料可作为猪的能量来源。在乌干达,玉米皮形成了牲畜饲料中使用的大部分成分,但它比其他谷物产品的价格更高。小麦糠可以用于猪的饮食中,但它的掺入水平取决于动物的生长阶段。因此,需要关心的是,当使用这种产品的高纤维,影响其利用效率。缪尔等。(1992)报告饲喂这种副产品的猪的良好性能。本研究的目的是确定玉米皮和小麦糠作为日粮能量源对生长猪生长、消化率和胴体品质的影响。

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.
