摘  要：
文章旨在研究断奶仔猪生长早期和后期采用不同结构日粮对其生长性能和营养物质表观消化率的影响。试验选择体重一致、21 d断奶的三元仔猪400头,随机分为5组,每组4个重复,每个重复20头。试验早期(21～42 d)采用5种日粮,处理1组(对照组)为玉米-豆粕-低乳糖-低鱼粉型,处理2组为膨化玉米-豆粕-高乳糖-高鱼粉型,处理3组为玉米-豆粕-高乳糖-高鱼粉型,处理4组为膨化玉米-豆粕-高乳糖-低鱼粉型,处理5组为膨化玉米-豆粕-低鱼粉-高乳糖型。试验后期(43～64 d),将试验早期的猪只按每2个重复(同一组)分别饲喂A和B两种日粮,A为膨化玉米-豆粕-鱼粉-乳清粉型,B为全谷物日粮型。结果 :各组对21～28 d、29～42 d及21～42 d仔猪的平均日增重、平均日采食量和料比均无显著影响(P> 0.05)。与处理1组相比,其他各组显著降低了21～28 d、29～42 d及21～42 d仔猪的腹泻指数(P <0.05);试验早期和试验后期日粮对43～64 d仔猪各阶段的生长性能和腹泻指数均无显著影响(P> 0.05)。试验早期,与处理1组相比,处理2、4和5组显著提高30 d仔猪有机物的表观消化率(P <0.05);试验后期两种日粮对50 d仔猪有机物、干物质、粗蛋白质及总能表观消化率均无显著差异(P> 0.05)。结论 :在本试验条件下,与其他多样性日粮相比,21 d断奶仔猪饲喂玉米-豆粕、低乳糖和低鱼粉型日粮对生长性能无显著影响。断奶仔猪生长后期(43～64 d)日粮采用高蛋白谷物日粮可以促进生长性能。

摘  要：
This study aimed to evaluate the effects of different feed structures on growth performance and nutrient digestibility of weaning pigs. Four hundred 21 d weaning pigs were allotted to 5 groups with 4 replicates of 20 pigs for the starter phase,while 2 replicates at the same group for the later phase. For the starter phase,there were 5 diets,group 1 was the corn-soybean meal-high lactose-high fish meal diet,group 2 was the extruded corn-soybean meal-high lactose-high fish meal diet,group 3 was the corn-soybean meal-low fish meal-high lactose diet,group 4 was the extruded corn-soybean mealhigh lactose-low fish meal diet,group 5 was the extruded corn-soybean meal-low fish meal-high lactose,while for the later phase,group A was the extruded corn-soybean-fish meal-whey powder diet,group B was the cereal diet. Results showed that no significant differences in average daily weight gain,average feed intake and feed conversion ration were found among the groups at the starter phase(P >0.05). Compared with the group 1,other groups had lower diarrhea incidence(P <0.05). Both the starter and later phase diets had no significant effects on the growth performance and diarrhea incidence of 43 ～ 64 d pigs(P >0.05). At the starter phase,group 2,4 and 5 had higher apparent digestibility of organic matter than the group 1(P< 0.05),while the later phase diets had no significant effects on the nutrient digestibility of 50 d pigs. Based on the data in this experiment,we conclude that pigs at 21 d weaned fed diets based on corn and soybean meal with low levels of lactose and fish meal had the similar performance to pigs fed more complex diets,and from 43 ～ 64 d,pigs got optimal performance when fed diets based on cereal and high protein.
