摘    要:将48头平均体重约27 kg的杜×(长×大)三元杂交生长猪根据体重和性别分成4组,饲喂4种不同蛋白质水平日粮,3种试验日粮根据理想氨基酸模式配制.试验结果表明:①4组日增重与料重比差异不显著(P>0.05).15%粗蛋白组生长速度最快,14%粗蛋白组经济性能最好,平均增重利润比17%粗蛋白组多0.41元/kg.②14%、13%粗蛋白组血清尿素氮分别显著(P<0.05)、极显著(P<0.01)低于17%粗蛋白组.③4组猪舍期中、期末氨气质量浓度,14%、13%粗蛋白组分别显著(P<0.05)、极显著(P<0.01)低于17%粗蛋白组,各组硫化氢质量浓度无显著差异(P>0.05).

关 键 词:低蛋白日粮  理想氨基酸模式  生长猪  猪舍  NH3  H2S  生产性能

Abstract:Forty eight three way cross (Duroc X (Landrace x Yorkshire)) pigs, weighing 27kg ABW, were assigned into four treatments by weight and sex, and fed with the different levels of protein diets respectively. The trial diets were formulated according to the pattern of ideal protein for growing pig. The results showed that the dietary protein level did not influence ADG and FCR significantly ( P >0.05). The dietary protein level to attain maximum growth rate was 15% and 14% was best level in the economic efficiency, whose profit was increased 0.41 Yuan/kg of pig growth compared with 17% protein diet. N concentrations in serum urea of pig in the treatment with 14% and 13% protein diets were lower than those of pigs offered 17% protein diets ( P <0.05 or O<0.01). The NH 3 contents of pig room offered 14%, 13% protein diets were lower than those of the room offered 17% protein diets ( P <0.05 or P <0.01). The difference of H 2S contents in room was not significant among four groups ( P >0.05).
Keywords:Growing pig  Low-protein diet  Pattern of ideal protein  Growth performance  NH  3 and H  2S contents in room
