猪采食量下降的因素分析及营养调控策略
Factors for the decrease in feed intake and strategies for regulating nutrition of pigs
目的 确保生猪采食量正常和生长性能良好,提高生猪养殖效益。 方法 结合生猪养殖生产案例,查阅相关资料,对猪采食量下降的因素进行总结、归纳与分析,并提出对应的营养调控策略。 结果 影响生猪采食量的主要因素有疫病与非疾病两类:疾病因素包括消化系统疾病、传染性疾病以及口腔炎症等,非疾病因素包括饲料、管理及应激等,这些与养殖场的饲养管理有密切关系。 结论 通过科学的营养搭配、合理利用矿物质元素、微生态制剂及中草药制剂等方面,进行全面的营养调控,可以有效降低生猪采食量下降带来的危害,促进生猪养殖健康快速发展。
Objectives The feed intake and growth performance of pigs were studied to improve the efficiency of pig farming. Methods Factors contributing to the decrease in feed intake of pigs were analyzed based on the case study of pig farming industry and related literature. The corresponding strategies for regulating nutrition of pigs were proposed. Results The main factors affecting the feed intake of pigs were and non-disease-related elements. The disease-related elements included gastrointestinal diseases, infectious diseases, and oral inflammations. The non-disease-related elements included the feed, management, and stress. These were closely related to the feeding and management of farms. Conclusions Comprehensive nutritional regulation including the scientific nutritional combinations, rational utilization of minerals, microecological agents, and traditional Chinese medicines can effectively reduce the harm caused by the decrease in feed intake of pigs and promote the healthy and rapid development of farming pigs.
