The F_1 of Shorthorn×Mongolian cross adapts itself very well to the environmental conditions of the northern part of Hopei Province.They are strong-built, with low succeptibility to diseases. The F_1 has highly improved conformation over the Mongolian cattle, being more symmetrical, with refined head, increased body width; back and loins are straight, wide and long; ribs well-sprung, length of legs increased.They are more meaty than the Mongolian cattle.But their hind quarters are still not well developed and rather narrow, some of them with sloping and ridge-shaped hips. The udders of the F_1 cows are better developed, with thicker and more curved milk veins, and longer teats.The hair of the crossbred cattle is short and lustrous.The predominant coat color is red or roan, cattle of black, black and white, yellow, yellow and white colors are next numerous, while those of brown, white, steel grey, and wild cat are still less in number. The development and growth of F_1 attained a higher level.Average birth weight of bull calves is 25.13kg, and of heifer calves 23.14kg, they increased by 31.36% and 32.46% respectively than the Mongolian calves.Their weight at 6 months increased by 26.12% and 32.48% respectively, at 12 months by 65.85 and 90.10% respectively.Average weight of F_1 cows at 1st freshening is 399.04kg, 2nd freshening 405.80kg, 3rd freshening 436.00kg, an increase of 41.75%, 26.54% and 31.92% as compared with Mongolian cows at respective freshenings.F_1 bulls at 3 years of age weigh 577.5kg, at 4 years 750.0kg. The height at withers of mature bulls is 141.00cm on the average, body length 175.00cm, heart girth 215.0cm, increased by 17.50%, 17.69% and 20.14% respectively.The average height at withers of mature cows is 124.61cm, body length 146.17cm, heart girth 181.71cm, increased by 1198%, 10.40% and 10.03% respectively. Average length of lactation period of F_1 cows is 267.82 days, an increase of 108.24 days.Average production of milk is: 1st lactation 1,625.25kg, 2nd lactation 1,977.53kg, 3rd lactation 2,342.43kg, increased by 290.36%, 285.27% and 302.22% respectively as compared with Mongolian cows.Cows with milk production over 2,000kg at 1st lactation amounted to 30.80% of the total number of cows, the highest producer gave 3,337.2kg.Average fat content is 4.60%, they range from 3.93% to 5.5%.

(1) Large amounts of Cl. perfringens type C toxin could be produced when the organism was cultivated either in liver broth or in two types of modified V. F. media. (2) Liver broth which contained 10-40 per cent liver pulp (w/v), proved to be more suitable for the production of Cl. perfringens type C toxin in 16 hours of growth. (3) On comparing the potency of the formalized, alum precipitated, and aluminum hydroxideadsorbed vaccines on sheep and rabbits, results were as follows: when the vaccinated animals were challenged by Cl. perfringens type C, aluminum hydroxide-adsorbed vaccine appeared to be the best, alum precipitated vaccine appeared to be fairly good, and formalized vaccine the least satisfactory. On the other hand, when vaccinated animals were challenged with Cl. septicum, the formalized, and the alum treated vaccines were more effective than aluminum hydroxide adsorbed vaccine. (4) Rabbits or sheep which received the adsorbed vaccine intramuscularly attained immunity better than those which received the vaccine subcutaneously. (5) In a series of experiments, two out of three lots of alum precipitated, and aluminum hydroxide-adsorbed vaccines did not lose their potency in protecting against struck after being kept for 22-26 months at 10-30℃, but the other lot decreased in potency after 20 months. However in another experiment, all of three lots of vaccines showed encouraging result in protecting against braxy as the vaccines still maintained their potency after being kept for 20-26 months under the same conditions described above. (6) The immunity established in sheep immunized with either 5 ml of alum precipitated or 5ml of aluminum hydroxide-adsorbed vaccine was prolonged for 6.5 months as determined by artificial challenge with struck and for 7.5 months by braxy. (7) Sheep which received 2ml of the aIum treated mixed vaccine withstood a challenge of braxy but 4-6 ml of the same vaccine was required for struck.

本报告对猝狙菌的培养条件,进行了試驗。証明使用PH7.6含肝块10%的厌气肉肝湯,用于培养猝狙菌,培养16小时,是能够使該菌产生良好毒素的。进行了福、明、鋁三种疫苗的效力比較試驗,証明含鋁胶及明矾等佐剂的菌苗对猝狙能提高效力,其中鋁胶提高效力更为显著,但对快疫效力未見提高。对菌苗的保存期,免疫期,免疫剂量以及免疫方法等进行了試驗。証明混合菌苗保存20个月有的批对猝狙效力显著降低。保存22—24个月对快疫效力仍良好。用混合菌苗5毫升免疫的綿羊,經6个半月对猝狙,9个月对快疫仍有免疫力。用明矾混合菌苗免疫綿 羊,免疫剂量2毫升对快疫,4—6毫升对猝狙,可获得良好结果。肌肉注射菌苗的效力此皮下注射显著优越。

Summary Live weight and body measurements of 3442 calves of both sexes, 925 heifers,and young bulls and 786 cows of Heilungkiang dairy cattle (B. W.) and Heilungkiang steppe cattle (Y. W.), are collected at a state farm at Sartu district dnring 1955-1962. 1. Birth weights of the B. W. and Y. W. were 38.6 and 42.3 kg. for males, 36.7 and 36.5 kg. for females respectively. Lightest calves were born from the first calving (B. W.: ♂ 34.9 and ♀. 30.0 kg.; Y. W.: ♂ 36.0 and ♀.33 kg.). Heaviest calves were born from...

Summary Live weight and body measurements of 3442 calves of both sexes, 925 heifers,and young bulls and 786 cows of Heilungkiang dairy cattle (B. W.) and Heilungkiang steppe cattle (Y. W.), are collected at a state farm at Sartu district dnring 1955-1962. 1. Birth weights of the B. W. and Y. W. were 38.6 and 42.3 kg. for males, 36.7 and 36.5 kg. for females respectively. Lightest calves were born from the first calving (B. W.: ♂ 34.9 and ♀. 30.0 kg.; Y. W.: ♂ 36.0 and ♀.33 kg.). Heaviest calves were born from the 6th calving (B. W.: ♂. 41.5 and ♀ 40.6 kg.; Y. W.:♂ 46.6 and ♀ 38.7 kg.). 2. Greatest relative rate of gain occurred in the 1st month after birth and declined successively throughout the preweaning months. Absolute gain was greatest during the 3-4 months period. Average weaning weight in females were 173.5 kg. for the B. W. and 169.4 kg. for the Y.W. After weaning, their growth rate was slow and growth curve irregular. Average live weight of females at 24 months were heavier for B. W. than Y. W. A reverse picture was found in mature cows of different ages, the Y. W. averaged 570.5 kg. and B. W. only 532.6 kg. at the age of 5 years and over. Live weight at 11 years of age for the Y. W. and 9 years of age for the B. W. were found to be the heaviest. 3. The growth impulse of heart girth was the greatest, body length the next, and the height at withers was the smallest. These results are in agreement with those basic rules obtained by Chervensky, that the growth rate of axial skeleton was greater than peripheraI skeleton. 4. There was a significant correlation between birth weight of heifer calves and weight of mature cows (r= 0.216, P < 0.01). The birth weight and the gains at 1,3 and 6 months of age were also significantly correlated (r=0.399, P < 0.01, r=0.319, P <0.01. r= 0.282 P <0.05 resp.). No significant correlation existed between birth weight and length of dry period and between birth weight and milk yeild in both breeds.
