Chinese Simmental breeding of new varieties and efficient production
Transplant survival rate of 45%, easing the supply situation purebred cows. Established in Xinjiang in Chinese Simmental Breeding Committee embryo Engineering Center, and increased seed production and accelerating the speed for the species. l1. In addition, for the germplasm characteristics of Simmental series of studies, including the main reproductive traits of genetic factors, the Chinese Simmental cattle feed conversion efficiency and the expected effects of selection, microsatellite DNA markers associated with the production performance analysis on the twin traits of a large gene research, opening up the Chinese woolen rug Blumenthal core group of cattle breeding system (ONBS) the effect of the Chinese Simmental Genetic factors secondary to improve the marbling score of beef and so on. Second,[link widoczny dla zalogowanych], the Chinese Simmental population performance, Establish and improve the core group of open breeding system in two foot of Taihang farming and pastoral areas, northern Anhui, eastern Henan, northern Jiangsu agricultural areas, Plain, Horqin grassland established three local groups, improving the group accounted for 70% of cattle a 9o%; breeding area size of up to 1.75 million cattle. Selection out of the 2178 core group of cow milk production has reached more than 4300 kilograms annually, of which 1119 reached 5,200 kg, the average fat content 4.03%. Based on 97 test results of fattening cattle, average daily weight gain 1.106 kg, l8-22 months before slaughter live weight 573.6 kg, dressing percentage 61.4%, net meat rate of 50. Ol%, reached the advanced level in developing countries. Third, the Chinese Simmental cream for the kind of system, the establishment of effective use of artificial insemination (AI) and joint stock limited company in Animal Husbandry Co., Lu Address: Spark Road, Science City, Fengtai District, 2o one is layer I, Ji: 1011070 Headquarters Tel: 010 - 836O7777 Fax: 836 079 ~ bio-turned products division, Meng Chen Tel :010 drug made -83607766 Fax: 83607997 Beijing Branch feed, trade Branch Tel :010-83 �� D 799 Fax: 6079% @ sip Shao Rong scattered network : one. eahb. net53 @ technology and promotion (special column in the National Agricultural Science and Technology): Recommended new achievements in science and technology high-yielding mother �� Simmental cattle embryo transfer (ET) technology to improve the quality hybrid improved cattle milking cows Seoul, fattening, feeding male and female seeds strength and quality of cattle feed using a set of processing technologies, developed a gene flow rate, combined with ultrasound high Simmental beef cattle feeding and management regulations and the wave of live fat measurement range of DNA genetic markers, bull progeny test Practice assisted selection means, Modern genetic evaluation and breeding registration rules. These systems and germplasm establishment of monitoring techniques to optimize matching, supporting technologies, and the strength of specifications and options, integrated application of embryonic development and implementation of hygiene standards, accelerate the rapid propagation material supporting technology projects, power Simmental promote the evolution of cattle breeding and seed production and seed supply for the species ability to speed up the process. Beef cattle breeding and large-scale industrial technology four around production Simmental implementation process research and development, Hebei, industry, the establishment of the integrated technology system Shandong and Henan provinces to the cattle industry is now the system includes the following technologies: construction of the project and beef cows across the project to establish breeding system with calves,[link widoczny dla zalogowanych], beef cattle health and improvement projects over the past carried out the optimization of production systems, cattle feed, 70% bulls, from raising the topic integrated breeding technology research and development, business base seven national breeding stock market. Raising beef cattle production model products and management science in the study, led by Inner Mongolia to establish management systems, the ancient scale production of beef cattle,[link widoczny dla zalogowanych], Hebei, Shanxi, Jilin, Henan phase disease monitoring, prevention and environmental control technology beef industry following the establishment of test-based technique research, high-quality beef slaughter and processing, and land. In Simmental-based milk, beef, fresh technology. Meat products have entered the industry, promote the use of a production, has been applied and the social process in the pilot project had been on our cattle industry,[link widoczny dla zalogowanych], especially the beef industry had a tremendous role in promoting and far-reaching positive impact. After years of breeding, the establishment of pure breeding and crossbreeding systems, livestock processing and circulation system, Simon tower stage. In addition, the rapid development of Xinjiang, northwest China, improved group size of up to 5O million 'head. Key development areas of hybrid cow milking, bull fattening, slaughtering, meat,[link widoczny dla zalogowanych], milk processing, export and other distribution channels have begun to take shape. To 2OO0, a total of 9 established a daily processing 393 tons of fresh milk daily processing of fresh milk powder series and 43.2 tons of liquid milk and milk series pattern processing lines, 9 and 2 brands of liquid milk
