【摘要】 根据早期断奶仔猪的消化生理特点和营养需要,研制了“三阶段日粮”。为验证其效果,将446头21日龄断奶的杜长大三元杂交仔猪分成2组,每组5个重复。对照组饲喂市售料,采用两阶段饲养模式;试验组饲喂“三阶段日粮”,采用3阶段饲养模式。试验结果:21～49d、50～65d、21～65d平均日增重,对照组分别为335±21g、394±29g和356±13g:试验组分别为353±22g、506±62g和408±37g,比对照组分别提高7.05%、28.43%(P<0.01)、14.61%(p<0.01)。21～49d、50～65d、21～65d平均料肉比,对照组分别为1.56±0.04、1.91±0.14和1.70±0.06:试验组分别为1.45±0.07、1.66±0.16和1.54±0.09,比对照组分别下降7.05%(P<0.05)、13%、(p<0.01)、9.41%(P<0.05)。试验表明,3阶段饲养模式较2阶段饲养模式仔猪的生产性能明显改善。更多还原

【Abstract】 We prepared a there phase diet for early-weaned pigs according to its digestive specificity and nutritional requirement. To investigate the effect of "Three Phase Diets" on Performance, 446 weaned pigs (Landrance × Large white × Middle Yakshire) of 21 d were allotted to two treatments. Every treatment included 5 replications. The control treatment were fed with marked super quality feed, all pigs were fed a phase land phase 2diet. The testing treatments were fed with the three-phase diet. The results showed: the control ADG of 21-49d, 50-65d and 21-65d were 335±21g, 394±29g and 356± 13g,respectively;The testing were 353?2g, 506±62g and 408±37g, respectively, improved 7.05%, 28.43% (p<0.01) and 14.61% (p<0.01) compared to the control, respectively. The average gain/feed of the control of 21 -49d, 50-65d and 21-65d were 1.56±0.04, 1.91 ±0.14 and 1.70 ±0.06, respectively; the testing were 1.45 ± 0.07. 1.66 ± 0.16 and 1.54 ± 0.09, respectively, decreased 7.05% (p<0.05), 13% ( p<0.01), 9.41% ( p<0.05) compared to the control, respectively. The experiment showed the effect of the three-phase diet on the early-weaned pigs’ performance is significantly better than the two-phase diet.更多还原
