不同能量和蛋白质水平对桂科猪生产性能的影响

Effect of Different Dietary DE and Protein Levels on Production Performance of Gui-ke Pig

为研究饲料中粗蛋白质及能量水平对桂科猪生产性能的影响,试验分为两个阶段,即生长期(30~60 kg)和肥育期(60~90 kg),以不同营养水平的饲料进行饲喂。结果表明,在30~60 kg阶段,采用蛋白质水平15.5%和能量3 200 kcal/kg的饲料饲喂桂科商品猪,可获得最佳的生产性能;在60~90 kg阶段,采用消化能为3 200 kcal/kg的饲料饲喂桂科商品猪,可获得最佳的生产性能。

In order to determine the effect of different dietary digestible energy and protein levels on production performance of Gui-ke pig, the experiment was conducted in two stages： the growing period （30-60 kg） and fattening period （60-90 kg）. Experimental pigs were fed with different nutritional levels of diets. The results show,ed that production performance of Gui-ke commercial pig was optimal when they were fed by the diet of 15.5% protein level and 3 200 kcal/kg digestible energy during the growing period （30-60 kg）. And production performance of Gui-ke commercial pig was optimal when they were fed by the diet of 3 200 kcal/kg digestible energy during the fattening period （60-90kg）.
