粗饲料在猪养殖中的应用及注意事项

Application of Roughage in Pig Breeding and Matters Needing Attention

粗饲料主要是指纤维素或木质素含量较高的青绿饲料,也是包裹植物颗粒的外壳或是植物的茎叶部分,其中口感较硬,粗纤维含量多,猪采食后不容易被消化和吸收,营养成分含量低,并且机体的利用率也较低。因为粗饲料所含的木质素能够阻碍猪机体消化系统里面的消化酶与纤维素和半纤维素进行充分接触,这样就会更加降低猪对粗饲料的消化和吸收。实验证明:饲料中粗饲料含量较高时,猪机体对饲料的利用率大大降低。所以在实际生产中,需要合理使用粗饲料,在满足猪生长发育的同时,还可以节省大量饲料成本,为养猪场创造更高的经济效益。

Coarse feed mainly refers to green feed with high cellulose or lignin content.It is also the shell of plant particles or the stems and leaves of plants.It has a harder taste and a lot of crude fiber.It is not easy for pigs to be eaten after eating.Digestion and absorption,the content of nutrients is low,and the utilization rate of the body is also low.Because the lignin contained in roughage can prevent the digestive enzymes in the digestive system of pigs from fully contacting cellulose and hemicellulose,which will further reduce the digestion and absorption of roughage by pigs.Experiments have proved that when the content of coarse feed in the feed is high,the utilization rate of the feed by the pig body is greatly reduced.Therefore,in actual production,it is necessary to use roughage reasonably.While satisfying the growth and development of pigs,it can also save a lot of feed costs and create higher economic benefits for the pig farm.
