摘  要：
本试验选择体重60千克左右、出生日期相近的北京黑猪72头(阉公猪和母猪各半),分为4组。Ⅰ组和Ⅱ组饲喂蛋白含量14％的饲料;Ⅲ组和Ⅳ组饲喂蛋白含量16％的饲料。当猪体重约为55～65千克时开始,Ⅰ组和Ⅲ组每天注射1ml 75mM NaHO_3为对照组;Ⅱ组和Ⅳ组每天注射猪基因工程生长激素1ml(含2mg)。注射28天后采血测定其血浆中葡萄糖、非蛋白氮和游离脂肪酸含量。结果表明:注射猪生长激素可使猪血糖和血浆游离脂肪酸含量升高(P<0.01);而使血浆非蛋白氮含量下降(其中16％蛋白饲料组差异显著,P<0.05)。在本实验条件下饲料蛋白含量和性别对猪血浆葡萄糖、游离脂肪酸和非蛋白氮含量无明显影响。本文还对这些变化的意义进行了讨论。

摘  要：
The experiment was conducted to determine the blood concentrations of glucose, non-protein nitrogen and free fatty acids in porcine so-matotropin treated Beijing Black pigs fed two diets with different protein content. The purpose was to identify the changes of energy transport in form of glucose , the rates of protein degradation and i'at motivation as effected by porcine somatotropin.Seventy-two Beijing Black pigs with similar body weight ( about 60 kg ) and birth date were selected(36 gilts and 36 barrows ) .After 10 days adaptation to experimental condition, the pigs were divided into 4 groups ( for each group, there were 9 gilts and 9 barrows ) .The treatments included 14% and 16% diet protein content, zero and 2 mg/pig/day somatotropin injection for 28 days. There was no effect of diet protein and sexuals on plasma biochemical parameters. The porcine somatotropin treatment enhanced plasma glucose ( P<0.01 ) from 147.40±29.76 and 147.43±24.76mg/dl to 115.39±29.09 and 112.69±18.12 mg/dl;The treated pigs had lower plasma NPN ( 30.57±6.01 and 31.86±9.05mg/dl)than controls(34.02±7.20 and 40.04±6.99mg/dl ) ( P<0.10, P<0.05).The plasma free fatty acids concentration increased markedly in porcine somatotropin treated pigs ( 558.58±384.33 and 517.72± 281.42μEq/L)compared with those of con-trols( 270.13±111.93 and 292.00±108.72nEq/L) .The results suggested that porcine somatotropin inhibited protein degradation and facilitated fat motivation, at the same time shiftep glucose from adipose tissue to muscles.
