饲料突然变换对配套系生猪肥育性能影响的研究

选择配套系生猪为研究对象,研究饲料突然变换对配套系生猪育肥性能的影响。虽然配套系生猪的生长速度快、饲料利用率高、瘦肉率高、饲养时间短,但其适应能力、耐粗饲能力、抗应激能力却很差,因此,必须在科学的饲养管理条件下才能取得良好的饲养效果。否则易发生PSS(应激综合征)、PSE(肉色苍白/蛋白质松软无弹性、切面渗水的劣质肉),给养殖户造成重大损失。

Effects of Sudden Feed Replacement on Fattening Performance of Synthetic Line Pigs

The aim of the study was to investigate the effects of sudden feed replacement on fattening performance of synthetic line pigs.The synthetic line pigs have fast growth,high feed conservation ratio,high lean meat percentage and short feeding time,but they have very poor adaptability as well as resistance to roughage and stress.Therefore,scientific breeding should be performed with good feeding management so as to achieve good breeding results.Otherwise,pigs will tend to suffer from PSS(porcine stress syndrom...
