抽样方法对出口冻肉类产品微生物检验影响的研究

本调研是按据国家质检总局颁布的《进出境肉类产品检验检疫管理办法》和外贸合同、信用证中对出口冻肉类产品要求进行微生物学检验而开展的。通过调研 ,我们发现不同的抽样方法 ,冻肉品微生物检验结果不同 ,抽样方法对出口冻肉类微生物检验结果影响较大 (P>1) ,为确保冻肉品微生物检验的准确性 ,建立适宜的冻肉类微生物检验抽样方法十分必要。1前言以往 ,我们对出口冻肉类产品检验以感官检验为主 ,必要时做实验室检验。但现今出口冻肉类产品贸易合同、信用证中纷纷要求对冻类产品进行微生物检验 ,并对微生物指标进行严格的限定。国家质检总…     

超冷藏安全期冻肉检疫情况分析

超冷藏安全期冻肉（超期冻肉）,是指库温－１５℃－１８℃的条件下贮藏期为７个月～１０个月,超过此限则为非贮藏安全期限。据查证,该规定系商业部对内销白条肉所做的规定。农业部尚未制定出相关标准。我市每年要从外地调进大批的冻猪肉及副产品等投入市场,这些冻肉调进时已超期,一部分随即在市场销售,相当部分继续存入冷库保管。１９９８年２月,在对库存冻肉进行的一次检查中发现有２６８０００ｋｇ冻肉已超出安全期,有的达１６个月之久,超期冻肉占总库存量的３７．７２％。为了保证冻肉上市质量,笔者于５月初至６月对１８０００…

Strategies for Using eFSH for Superovulating Mares

The standard treatment for superovulation of mares is to administer equine follicle-stimulating hormone (eFSH) for 4 to 5 days to stimulate multiple follicles and human chorionic gonadotropin (hCG) to induce synchronous ovulations. Objectives of this study were: (1) to determine whether a short-term (3-day) eFSH treatment protocol would result in similar ovulation and embryo recovery rates compared with the standard eFSH protocol; (2) to determine the efficacy of a decreasing dose of eFSH (step-down protocol) on ovulation rate and embryo recovery; (3) to compare the efficacy of hCG and recombinant equine luteinizing hormone (reLH) for inducing ovulation in FSH-treated mares; and (4) to compare embryo recovery rates and embryo size when mares are flushed at 6.5 or 7.0 days after ovulation. Forty light-horse mares were used in 2005 (experiment 1) and 20 different mares were used in 2006 (experiment 2). In experiment 1, mares were randomly assigned to one of three treatment groups: (1) untreated controls, (2) standard eFSH treatment (12.5 mg intramuscularly twice daily), and (3) 3-day eFSH treatment. In experiment 2, mares were randomly assigned to one of four treatments: (1) untreated controls, (2) standard eFSH protocol, (3) 3-day eFSH treatment, and (4) step-down eFSH treatment (12.5 mg twice daily day 1, 8.0 mg twice daily day 2, 4.0 mg twice daily day 3). Within each treatment, mares were given either hCG (2,500 IU) or equine LH (750 mg, EquiPure LH; reLH) to induce synchronized ovulations. Embryo recovery was performed either 6.5 or 7.0 days after ovulation. In experiment 1, numbers of preovulatory follicles and ovulations were less for mares in the 3-day treatment group than the standard group, but were greater than for controls. Embryo recovery per flush was higher in the standard group (2.6) than the 3-day eFSH treatment (0.8) or control groups (0.8). In experiment 2, the number of preovulatory follicles and number of ovulations were greater in the standard and 3-day treatment groups than in control and step-down groups. The percent embryo recovery per ovulation and mean embryo grade were similar for all groups; however, the embryo recovery per flush was higher for mares in the standard treatment than controls (1.3 vs 0.6) but was similar to the 3-day (1.1) and step-down (0.8) treatments. Embryo recovery was similar for flushes performed on days 6.5 and 7.0 post-ovulation. The percentage of control mares ovulating within 48 hours in response to hCG or reLH was similar. In contrast, a higher percentage of eFSH-treated mares ovulated within 48 hours in response to reLH than hCG (92% vs 71%). In both years, the 3-day eFSH treatment protocol resulted in a greater number of preovulatory follicles and a greater number of ovulations than untreated controls. Unfortunately, the increased ovulation rate for mares administered eFSH for 3 days did not result in a greater number of embryos recovered per flush in either year. Use of a step-down eFSH treatment protocol resulted in fewer preovulatory follicles, fewer ovulations, and fewer embryos as compared with the standard eFSH treatment. In conclusion, the standard eFSH treatment resulted in a greater embryo recovery rate per cycle than either the 3-day or step-down treatment protocols. Recombinant equine LH was more effective than hCG in causing ovulation in eFSH-treated mares.     

服务农业服务社会

在迎接新世纪,庆贺新千年的时候,饲料行业如同其他行业一样,也在筹划今后的发展问题。研究任何产业的发展,都要研究自身的特点,还要研究与其他产业的关联。饲料工业,是个关联性很强的产业。最明显的是,依托于农业,又服务于农业。饲料工业的原料,绝大部分直接来源于农业,没有农业作基础,就没有饲料工业;没有发达的农业,也就没有发达的饲料工业。因此,服务农业,是发展饲料工业的题中应有之义。民以食为天。服务于农业,服务于“菜篮子”工程,也就是服务于社会。我国饲料工业的发展,为农业,为养殖业,为人民生活的改善,做出了巨大的贡献。据国家…     

Transgenic pigs for xenotransplantation for humans]

Transgenic livestock have been generated via microinjection of DNA-constructs into pronuclei of zygotes. However, efficiency is low and only 1-3% transgenic offspring are to be obtained. Integration of the transgene occurs at random and expression is independent from the number of integrated copies but can be affected by the integration site. To overcome the shortage of human organs, transgenic pigs have been generated that express human complement regulatory genes. This approach enables to overcome the hyperacute rejection response as shown by an average survival rate (40-90 days) of the immunosuppressed primate recipients receiving a heart from a transgenic pig. It is expected that transgenic pigs would be available as organ donors in the next 5-10 years. A major prerequisite, however, is the prevention of the potential transfer of pathogenic microorganisms, in particular porcine endogenous retroviruses (PERV). Improvements of the efficiency in the generation of transgenic pigs will be achieved by the use of genetically modified donor cells in nuclear transfer technology (cloning).
