<正> 随着养猪区域间市场信息和商品流通功能的加强,在饲料原料和猪价杠杆的调节下,养猪业内的竞争变得将越来越激烈,养猪的利润将日趋降低,同时猪场的疾病状况也越来越复杂。为了增强企业的核心竞争力和强化生物安全意识,集约化猪场内自行配制预混料来生产营养平衡的全价饲料将越来越成为主流趋势。 相似文献

无锡正大畜禽有限公司已有18年的发展历史。在这18年的发展中,无锡正大从一个技术服务公司转型为贸易公司,再从贸易公司转型为饲料生产公司与贸易服务为一体的综合性企业。每一次转型,无锡正大都能抓住市场发展机遇,紧踩市场发展的脉点,都能将企业自身的人力、物力资源与市场的发展完善结合,获得了稳步过渡与长足发展。这些成功,不仅需要企业高层具有远见卓识,更需要企业具备完善的应对与转变机制,而这些机制又是由企业核心竞争力来决定的。生物科技是新世纪的发展主流,而无锡正大又在无锡高新技术开发区征地100余亩,投资6000万元组建太泓(集团)生物科技有限公司。因此,本文就无锡正大核心竞争力等问 相似文献

1. The fermentation of poultry manure in an attempt to increase its value for poultry diets was studied.
2. Microbial strains for the efficient elimination of uric acid were isolated.
3. Suitable, cheap carbon sources (methanol, glycerol, glucose) were tested in attempts to increase cell yield.
4. These criteria were used to study the 41 bacterial and 8 yeast strains which were the most prolific on slants and which were isolated from experiments with a shaker. A strain was selected for experimentation with a fermentor.
5. Fermentor experiments were done on a laboratory scale (101) and in a non‐sterile semicontinuous system (150 1), cell mass production being similar in both systems. 相似文献

Five hundred sixty-nine Salmonella were isolated out of 4745 samples from poultry products, poultry, and poultry environment in 1999 and 2000 from the Pacific northwest. These Salmonella were identified to their exact source, and some were serogrouped, serotyped, phage typed, and tested for antibiotic sensitivity. Food product samples tested included rinse water of spent hens and broilers and chicken ground meat. Poultry environment samples were hatchery fluff from the hatcheries where eggs of grandparent broiler breeders or parent broiler breeder eggs were hatched and drag swabs from poultry houses. Diagnostic samples were of liver or yolk sac contents collected at necropsy from the young chicks received in the laboratory. Of these samples tested, 569 were Salmonella positive (11.99%). Ninety-two Salmonella were serogrouped with polyvalent somatic antisera A-I and the polymerase chain reaction. Somatic serogroups B and C comprised 95.25% of all the Salmonella. Out of a total of 569 positive samples, 97 isolates of Salmonella were serotyped. A total of 16 serotypes and an unnamed Salmonella belonging to serogroup C1 were identified. The Salmonella serotypes were heidelberg (25.77%); kentucky (21.64%); montevideo (11.34%); hadar and enteritidis (5.15% each); infantis, typhimurium, ohio, and thompson (4.12% each); mbandaka and cerro (3.09% each); senftenberg (2.06%); berta, istanbul, indiana, and saintpaul (1.03% each); and an unnamed monomorphic Salmonella (2.06%). Ninety-two Salmonella were tested for drug sensitivity with nine different antimicrobials. All of the 92 Salmonella were resistant to erythromycin, lincomycin, and penicillin except one sample (S. berta), which was moderately sensitive to penicillin. All of the tested Salmonella were susceptible to sarafloxacin and ceftiofur. The percentages of Salmonella susceptible to sulfamethoxazole-trimethoprim, gentamicin, triple sulfa, and tetracycline were 97.83%, 92.39%, 86.96%, and 82.61%, respectively. 相似文献

2.2德国的家禽生产
最近的统计数据显示,1999年德国禽肉生产总量为80.68万吨,加上进出口部分,总量为124.87万吨,自给率大约为65%.1999年德国肉鸡的产量为43.82万吨,与1998年的44.44万吨相比略有下降,而总的消费量为65.51万吨,与1998年的65.38万吨相比继续缓慢而稳步的上升.1994年德国鸡肉的平均消费量人均7.0公斤,1997年人均7.8公斤,1998年人均为8.0公斤,1999年仍保持在这一水平上.德国国内禽类加工厂的肉鸡加工量达到了37.86万吨,与1998年的36.46万吨相比略有上升.德国肉鸡生产主要由一些大型的集团所控制,德国排名前三位的肉鸡生产公司的总产量占了整个肉鸡生产的90%.具体情况如表5. 相似文献
