This is the second report of the results obtained on the improvement of Mongolian sheep by crossbreeding on the May First State Farm in Charhar, Inner Mongolia, and Chapei State Farm, in Changpei of Hopei Province (Formerly in Charhar). Mongolian ewes on these two Farms were crossed with rams of two finewool breeds-Soviet Merinoes and Caucasians,-and of a Medium-wool breed-Tsigai. all of which were introduced from the Soviet Union. The fleece of the Mongolian sheep on Chapei Farm is composed of 52.95°/o of true wool, 5.86% of hetero-typical fibres and 41.19% of hair (including kemp). When crossed with fine-wool rams, the true wool content rose to 82.32-87.36% in the F_1 generation, to 97.23-97.32% in the F_2 generation. Hair and kemp disappeared entirely on the shoulder sample of F_2, heterotypes decreased to 0.11%, while true wool content rose to 99.89%. The fleece of Mongolian sheep on the May First Farm contains 48.59% of true woo), which rose to 79.48% in the F_1 of Tsigai×Mongolian cross, and 91.17% in the F_1 of Soviet Merino×Mongolian cross. The results indicate that when Mongolian ewes are crossed with rams of finewool breeds, uniformity in fibre type can be attained in two generations. The fleece of F_2 sheep on the Chapei Farm is of 60-64's quality, the bettercared group being slightly coarser. When various groups of lambs and yearlings of F_1 and F_2 on Chapei Farm are compared, it is shown that under unfavourable environmental conditions, animals of the F_2 generation do not grow as fast as those of Ft, their constitution being also weaker than the latter. However, under better conditions, F_2 animals surpassed F_1 in either development of the body, fleece quality or fleece weight. It is evident that feeding and management conditions play a decisive role in animal improvement. The better-cared group of F_2 yearling ewes attained the following averages: body weight-41.3 kgs, height at withers-64.2 cm, fleece weight-4.69 kgs, yolk content of the fleece-20.65%, clean wool yield-53.85%, staple length-7.88 cm, average fineness of the fibres being of 60's quality.

1.察北牧场蒙古羊毛被中含细毛52.95%,一代杂种提高到82.32—87.36%,二代杂种提高到97.23—97.32%,五一牧场蒙古羊细毛含量为48.59%,一代杂种提高到79.48—91.17%。用细毛公羊与蒙古羊杂交,二代以后基本上已达到同质程度。 2.二代杂种羊毛细度为60—64支,营养较好者羊毛略粗。 3.将察北牧场小家畜组和二道渠组的二代杂种加以比较后,表明在不良的生活条件下,二代杂种发育较一代杂种为差,有退化现象。但在管理较为周到的条件下所育成的二代杂种,无论在体格发育和毛质、毛量方面都超过了不良生活条件下的一代杂种,证明主要关键在于饲养管理的条件。察北牧场小家畜组的二代杂种母羊,在一岁时平均体重达41.3公斤,体高64.2厘米,剪毛量4.69公斤,油脂含量20.65%,净毛率53.85%,毛长7.88厘米,细度60支,已达到或接近育种目标。

The results of many studies demonstrated that the chick has a specificrequirement for selenium for growth and maintenance of pancreas exocrine func-tion.The pancreas is the target organ of selenium deficiency in chicks,whileskeletal muscle,heart muscle,liver and other tissues are unaffected if vitaminE is adequate.Selenium deficiency in chicks fed adequate vitamin E results inpancreatic degeneration and fibrosis.Compared with selenium-supplementedchicks,selenium deficiency animals had lower plasma tocopherols,higher fecalneutral lipids,higher bile weigts,higher activities of plasma glutamic-oxa- loacetic transaminase,and lower activities of pancreatic lipase and trypsin.Itappeared therefore,that there was a decreased hydrolosis of fat due to pancreaticdegeneration and lack of lipase,which in turn led to the impairment of lipid-bilemicelle formation necessary for absorption of lipids and vitamin E.The additionof bile acid to the diet led to only partial correction of the impaired fat di-gestion and vitamin E absorption.Supplementation with free fatty acids andmonoolein increased vitamin E absorption and survival of chicks,but did notprevent pancreatic fibrosis.The biochemical studies showed a decrease in zymogen activity and increasein the activity of lysosomal enzymes cathepsin and acid phosphatase.Thatselenium was an integral part of the enzyme glutathione peroxidase (GSH-PX),it was demonstrated that this enzyme was related to the prevention ofexudative diathesis (ED) in the chicks.The levels of selenium in the diet wasshown to be highly correlated with the plasma GSH-PX activity,but Contorreported that GSH-PX was shown to be not correlated with pancreatic atrophy.Histochemical studies revealed that the invasion of macrophages accounted forthe observed increase in lysosomal enzymes.No evidence of lysosomal disrup-tion was obtained during the course of the pancreatic degeneration indi-cating that role of selenium in prevevention of pancreatic degeneration wasnot in the protection of lysosomal membranes of the acinar cells.The sequence of histological lesions began with vacuolization and hylinebody formation in the acinar.Subsequently,fibroblasts could be observed in in-creasing numbers in the interacinar spaces,while the acinar cytoplasm wasshrinking basally,thereby enlarging the central lumen of the acinus.Finally,theacini appeared,as rings of cells composed mainly of small,densestaning nucleiand were completely surrounded by fibrotic tissue.The islets are very conspi-cuous,but incretory function was not disordered.The β-islet cells are unaffec-ted by selenium deficiency.Athough hyaline body formation could be observed,the breathing function of the mitochondria was not impaired.Histological examination of the pancreases indicated that wheat and sele-nomethionine were the most effective-sources of selenium.Selenomethionine wasfour times as effective as either selenium or selenocystine with respect to pre-vention of pancreatic degeneration.Severe pancreatic atrophy is followed ED.The biological availability of selenium for prevention of ED in chicks has beenshown to be greater for feedstuffs of plant than for those of animal origin.Selenocystine was shown to be more available than selenomethionine,but not aseffective as sodium selenite.

大量的研究结果证实,硒对维持雏鸡生长和胰腺外分泌机能具有专一的作用。胰腺是雏鸡硒缺乏的靶器官,而骨骼肌、心肌、肝脏和其它组织在维生素E 充足时,不受缺硒的影响。硒缺乏的雏鸡,即使喂给足够的维生素 E,胰腺也发生变性和纤维化。与补硒鸡相比,硒缺乏鸡血清中生育酚较低,粪中的中性脂类和胆汁较多,血清谷草转氨酶活性升高,胰脂酶和胰蛋白酶活性较低。此结果归因于胰腺的变性和脂酶的缺乏,从而降低了脂肪的水解,破坏了脂类和维生素 E 吸收所必需的脂类——胆汁微胶粒的形成。在日粮中加入胆汁酸,仅仅部分地改善脂肪的消化和维生素 E 的吸收。补饲游离的脂肪酸和单油酸甘油脂,增加了鸡的维生素E 吸收和存活时间,但不能防止胰腺的纤维化。生物化学研究还表明,酶原活性降低,溶酶体酶中的组织蛋白酶和酸性磷酸酶活性升高。硒是谷胱甘肽过氧化物酶(GSH—Px)的重要组分,此酶与鸡的渗出性素质相关;而且日粮中的硒含量与血清中 GSH—Px 活性高度相关,但是,Contor 报道,GSH—Px 与胰腺萎缩没有相关性。组织化学的研究揭示了由于巨噬细胞的侵润,而导致溶酶体的酶增多。在变性的胰腺中未获得溶酶体破坏的证据,由此证明,硒防止胰腺纤...
