| 摘 要： | 本文研究不同营养水平对高产仔瘦肉型配套系不同杂交组合生长肥有猪生产性能的影响，结果表明：同一营养水平，大白♂×汉梅♀的生产成绩优于大白♂×长汉梅♀（P＜0．01）。同一杂交组合在不同营养水平，试验全期大白♂×汉梅♀以中营养水平饲粮生产成绩最好，其次是高营养水平和低营养水平；而大白♂×长汉梅♀在同样三种营养水平下，试验全期其排忧顺序为高营养水平、中营养水平和低营养水平；屠宰性状，各组合间无差异（P＞0．05），并均表现良好肉质；饲粮类型对各组合杂交猪内脏器官的影响变化不明显（P＞0．05），对胴体瘦肉率略有影响，但统计分析差异不显著（P＞0．05）。

| Abstract: | The essay is to account for the effect of the different nutritionlevel on the Ferformance of the growing (20-50kg) finishing (50-90kg) Figs. Theresults show that the performance of three-way cross Yorkshine×(Hamyslire×meishan) pigs is better than that of four-way cross Yorkshire× (landrece×meishan)×(Hampshire×meishan)] with the same nutrition leyel (P<0.01). When thesame cross line is fed with different nutrition leyel, three-way cross pigs getthe best performance with the medium nutrition level then better Ierformancewith the high nutrition level and the third good yerformance with the low nutrition leyel. For the four-way cross pigs, the best performance with the highnutrition level, then the better with the medium and last with the low. Aboutthe slanghter character, there is no difference between the two tyge cross line(P>0.05), both with bettet meaty guality Meanwlile, there is no different effecton the two-type pigs viscera when fed with different kinds of diet. |
