摘  要：
探讨在理想氨基酸模式下,日粮不同粗蛋白水平对泌乳母猪生产性能、粪便指标和氮排泄量的影响。选用3～6胎次、体况相似、预产期相近的60头长大二元杂交母猪,随机分成4个组,每组15头母猪,分别饲喂粗蛋白质18%(对照组)和粗蛋白质17%、16%、15%低蛋白氨基酸平衡的日粮,泌乳期21d。结果表明,日粮粗蛋白质水平降低1～3个百分点,对泌乳母猪生产性能、粪便水分、粪便pH值、粪便乳酸杆菌数和大肠杆菌数无显著影响(P>0.05),粪氮排泄量显著减少(P<0.05或P<0.01)。

摘  要：
The experiment was conducted to investigate the effects of amino acid balanced diets with different protein levels on productive performance,fecal indices and N excretion of lactating sows.Sixty crossbred sows(Large White × Landrace) sows,with 3-6 parity,similar body condition and parturition dates were selected and randomly divided into 4 groups and each group had 15 sows,and the lactation length was 21 days.Four groups of sows were fed respectively diets with different crude protein(CP) levels 18%(control group),17%,16% and 15%,and the latter 3 diets were low CP amino acid balanced diets.The results showed that the productive performance,fecal moisture conten,fecal PH,the quantity of lactobacillus and the quantity of Escherichia coli of lactating sows was not affected negatively(P>0.05),but the N excretion was decreased significantly(P<0.05 or P<0.01),while the reduction of dietary CP was 1% to 3%.
