【摘要】 通过饲养试验探讨南方高油玉米对生长肥育猪的生产性能的影响,进一步评价高油玉米用作猪饲料的效果及饲用价值。结果表明: ( 1 )生长期,A组和C组日增重显著高于B组和D组(P<0.05);日采食量和饲料利用率差异不显著(P>0. 05),但D组饲料利用率要优于其它各组。( 2 )肥育期和全期,日均增重、日均采食量和饲料利用率均无显著性差异(P>0. 05)。由此可见,高油玉米营养成分间比例不平衡,在没有提高饲料中优质蛋白饲料和氨基酸配比的条件下,饲喂高油玉米并不能改善生长肥育猪的生产性能。更多还原

【Abstract】 Through feed experiment, the influence of southern high oil corn (HOC) on production performance of growing-finishing pig was discussed and the effect and feeding value of high oil corn for hog feed meals was further assessed. Results showed that, (1) in production period, the daily gain of pigs in Group A and Group C was significantly higher than that of Group B and Group D ((P<0.05)), the difference of daily feed intake and the utilization of feed was insignificant, and the utilization of feed in Group D (HOC Group) was higher than other groups. (2) In finishing period and whole period, the difference of average daily feed intake and the utilization of feed were insignificant (P>0.05). Thus it can be seen that, without enhancing the proportioning of quality protein feed and amino acid, feeding HOC cannot improve production performance of growing-finishing pig for the imbalanced proportioning of nutrient contents of HOC feed.更多还原
