小平故居的蚕房院子

2003年,为隆重纪念邓小平同志百年诞辰,如期完成小平故居保护区《蚕房院子》陈列布展工作,广安市委办、市府办致函其所辖区市县征集：1920年前后有关养蚕、上蔟、收茧、缫丝、织绸工（用）具和历史资料,及新中国成立以来邓小平同志为蚕丝业的提词、指示、讲话和视察照片等历史资料。     

The former knackers yard in Zurich-Albisrieden: pathological findings in excavated animal bones

During archaeological excavations in the former knackers yard in Zurich-Albisrieden bones and joints of 8 horses and 1 mule were found and examinedfor pathological lesions. Degenerative changes (arthropathies, spondylosis and spondylarthrosis) as well as tooth irregularities were most often seen. One horse had a discospondylitis and spondylitis of C7 and Th1.

The effects of monthly formalin treatments on the survival of salmonellae in earthen sheep yard debris

Further field observations and laboratory studies on the biology and ecology of Damalinia bovis and Linognathus vituli, the two most common cattle louse species in New Zealand, are described.

The life cycle of D. bovis was completed in 27–32 days while L. vituli took 26–31 days. The winter distribution of both species on individual animals was similar with the heaviest concentrations on the cranial half of the body. The effect of the haircoat composition on distribution was examined; correlations between louse counts and hair diameters, colour composition of hair populations, hair and debris density, and sample sites were estimated for both species. The only significant correlation of D. bovis counts was with sample site. Findings were similar for L. vituli except that there was also a significant correlation between louse numbers and weight of hair and skin debris. The importance of self-grooming is discussed in relation to louse distribution.

Reasons for seasonal population fluctuations are considered including coat loss and temperature variations. It was shown experimentally that temperatures 5°C either side of the optimum 35°C prevented D. bovis eggs from hatching.     

An outbreak of the equine rhabdomyolysis syndrome in a racing yard

An outbreak of muscle stiffness and poor performance among 59 thoroughbreds at a Newmarket flat racing yard was investigated between the beginning of May and the end of June 1986. Over a third of the horses showed signs of muscular stiffness, and 38 had, at one or more of the sampling times, creatine kinase (CK) activities above 200 iu/litre and, or, aspartate aminotransferase (AST) activities above 300 iu/litre when they were sampled six to eight hours after exercise. The following season, at a similar time and stage of training, only four of 39 horses sampled had CK activities between 200 and 300 iu/litre, and three had AST activities between 500 and 600 iu/litre. Plasma samples from 18 animals sampled at the start of the investigation and 13 days later were tested for the presence of antibodies to equine herpesvirus (EHV). Ten of them showed a response highly suggestive of an EHV-1 infection. No significant abnormality was found in the fractional electrolyte values from seven randomly selected animals. Unusually high numbers of normally sized and stained fibres with centrally placed nuclei as well as groups of small muscle fibres were found in muscle biopsies taken from three animals which continued to have high enzyme activities and show recurrent signs of muscle stiffness.     

国内大豆市场动态

国内大豆市场此次明显比国际市场抗跌,这一方面是由于我国总体经济形势发展保持着良好的势头,另一方面与DCE市场上的资金顽强抵抗有关,但由于CBOT阴跌不止,随着多方的逐步退场,价格也下跌了400余点,其中5月、7月合约相即跌破2000元/t的整数关口,9月合约也是岌岌可危,我们将有关的信息和分析列入如下。     

全国畜禽养殖标准化系列报道之三：提升市场竞争力实现从庭院养猪到规模化养猪新跨越

20世纪70年代起,北京市顺义区担当首都"菜篮子",实现了从庭院养猪到规模化养猪的跨越.进入21世纪,随着顺义区工业化、城市化进程的加快,顺义区按照建设都市型现代农业的总体要求,坚持科学发展观,在原有规模猪场的基础上进行产业升级,着力发展高端、高效的种猪产业.     

农区牦牛、犏牛舍饲短期育肥效益分析

四川省是牦牛、犏牛生产大省,存栏量常年保持在高位,给草地生态环境造成巨大压力。但牦牛、犏牛养殖量的提升并未给牧民带来经济收入的增加,这与藏区冬春季恶劣的自然环境导致的营养缺乏密切相关。为解决这个问题,本试验将2.5~3.5岁的牦牛、犏牛运往四川省的农区(广汉)开展冬春季育肥研究,分析其带来的经济效益。通过120d的短期育肥,牦牛、犏牛分别增重64.00kg和85.80kg,增收645元/头和1299元/头。试验结果表明,牦牛、犏牛可以通过在农区进行冬春季育肥达到增收的目的。
