| 摘 要： | 本研究通过四次共620头猪的饲养试验,一次消化试验和144头猪的屠宰测定,就蛋白质营养水平问题,对杜湖猪<杜洛克×湖北白猪杂交一代>肥育性状和胴体性状的影响进行了研究。试验在等能量水平下,CP以2％的梯度、育肥前期由10.5％递增至18.7％,育肥后期由10.5％递增至16.8％。结果表明,饲养杜湖猪适宜蛋白质水平为:前期CP14.5％(含赖氨酸0.7％),能蛋比26.7:1;后期CPl2.5％(含赖氨酸0.54％),能蛋比32:1。

| Abstract: | Four feeding trials with a to-tal of 620 pigs, one digestion trial and one slaughter experiment with 144 pigs were conducted to study appropreate dietary CP level and carcass quality. with a gradient of 2 %, the CP levels of the iso-calotic starter feeds varied from 10.5% to 18.7%, while those of the isocaloric finisher feeds varied from 10.5% to 16.8%. The results indicated that optimum CP level for starter feed is 14.5% (Iysine = 0.7%), with a E/P ratio of 26.7 : 1 ; while that for finisher feed is 12.5% (Iysine=0.54% ) with a E/P ratio of 32 |
