饲喂频率对猪采食量及氮素利用影响的研究进展

Advances on Effects of Feeding Frequency on Feed Intake and Nitrogen Utilization of Swine

饲喂频率是指单位时间(1 d)内对饲养动物的饲喂次数,是影响动物营养物质的消化和吸收的重要因素。同时,饲喂频率在动物营养物质代谢和氮素利用中也能起到调节作用。因此,探索合适的饲养频率在一定程度上可以提高饲料利用率,缓解饲料浪费,对生猪生产具有重要意义。本文将有关饲喂频率对猪采食量及氮素利用影响的内容进行了综述,以期为生产实践选择合理饲养管理制度提供参考。

Feeding frequency refers to the number of feeding times per unit time(one day)for feeding animals,which is an important factor affecting the digestion and absorption of nutrients in animals.Moreover,feeding frequency can also play a regulatory role in nitrogen metabolism and nitrogen deposition.Therefore,it is vital in pig production to explore the appropriate feeding frequency in order to improve feed utilization and alleviate feed waste to a certain extent.In this paper,the effects of feeding frequency on feed intake and nitrogen utilization of swine were reviewed to provide a reference for scientific feeding and management in pig production.
