浅谈动物防疫、产地检疫、屠宰检疫三者的关系

随着我国经济的快速发展,人们的生活水平也在不断地提高,各种各样的食品出现在人们的餐桌上,但是食品安全问题也随之而来,层出不穷,成了人们最为关心的问题,当今社会上食品安全问题不断出现,给人们带来了很多困扰,其中猪肉的生产问题首当其冲,最令人担忧,因为生活水平的提高,使得猪肉成了各家各户餐桌上不可或缺的美食,但是由于猪肉的需求量大增,动物检疫、产地免疫、屠宰方面的达标率下降了许多,肉类的食品安全得不到有效的保障,本文就动物检疫、产地免疫、屠宰检疫三者的关系展开讨论,希望给光大消费者敲响警钟,从食品源头杜绝安全隐患,让消费者都能吃到放心肉类食品。

非典型猪瘟的表现形式、病因及其解决方法

在养猪生产中,有些猪场打了2次猪瘟疫苗,甚至打了3次猪瘟疫苗,结果仍发生了猪瘟。据此,笔者认为有发生非典型猪瘟的可能。原因主要有疫苗自身问题、免疫注射操作方法问题、环境方面的问题、免疫抑制和药物影响的问题、防疫程序上的失     

鹿、貂、狐、貉养殖业应纳入畜牧业范畴

针对近年来养殖界在鹿、貂、狐、貉等特种经济动物的管理体制和执法上产生的争议,较系统地阐述了野生动物和家畜(禽)的区别,野生动物驯养繁殖与养殖业的关系等有关学术概念,并对生产技术成熟,已形成各自独立产业的鹿、狐、貂等特种经济动物在管理体制上存在的问题,提出了按照《畜牧法》和相关畜牧兽医法律法规进行管理的合理化建议。     

规模猪场安全、高效、生态养殖技术

<正>规模猪场安全、高效、生态养殖技术在国外已被广泛应用,而我国因受技术、基础条件等诸多因素限制,还没有得到有效地推广利用。目前,市场上猪肉品质不高,药物残留,给人民身体健康带来直接或隐性危害;在国际市场上,因质量问题遭到技术避垒而受到出口限制。同时,规模饲养在扩张的同时带来了环境严重污染的问题,从而影响了生猪产业的发展乃至整个畜牧业的

信鸽的种、养、训

无论做什么事情都要自信,养鸽更不例外。常听到鸽友们抱怨,引进某人的鸽子或某血统的鸽子后不出成绩。其实不出成绩有时是鸽子的质量问题．但更多时候是鸽主本人的问题．即对自己没有信心．对引进的鸽子也没有信心和耐心,在“种、养、训”上做得不够．不好。

Supplementation of broodmares with copper, zinc, iron, manganese, cobalt, iodine, and selenium

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P > .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk, mare serum, or foal serum were observed. In experiment 2, 6 pregnant mares received the same concentrate as group A (group C), and 8 mares received the same concentrate fortified with 4× the trace mineral premix (group D). Group C mares had higher serum Zn concentration at 1 day (P < 0.01) and 56 days (P < 0.04). Group C mares had higher milk Fe concentration at 28 days (P < .01), and group D mares had higher milk Cu concentration at 56 days (P < .01). Group C foals had higher serum Cu concentration at 14 days (P < .03). The results from this study provide no evidence to indicate that supplementing late gestating and lactating mares with higher dietary trace mineral levels than those recommended currently by NRC has any influence on foal growth and development, or on the Cu, Zn, and Fe concentrations of the mare milk, mare serum, or foal serum.     

Comparisons of Angus, Charolais, Galloway, Hereford, Longhorn, Nellore, Piedmontese, Salers, and Shorthorn breeds for weight, weight adjusted for condition score, height, and condition score of cows

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n = 12,188) of 2- to 6-yr-old cows (n = 744) from Cycle IV of the U.S. Meat Animal Research Center's Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation code (PL), and breedgroup as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as a linear covariate. The model for CH excluded PL. Random effects were additive genetic and permanent environmental effects associated with the cow. Differences among breed groups were significant (P < 0.05) for all traits and were maintained through maturity with few interchanges in ranking. The order of F1 cows for weight was as follows: Charolais (506 to 635 kg for different ages), Shorthorn and Salers, reciprocal Hereford-Angus (HA) with 1980s sires, Nellore, HA with reference sires, Galloway, Piedmontese, and Longhorn (412 to 525 kg for different ages). Order for height was as follows: Nellore (136 to 140 cm), Charolais, Shorthorn, Salers, HA with 1980s sires, Piedmontese, Longhorn, Galloway and HA with reference sires (126 to 128 cm). Hereford and Angus cows with reference sires were generally lighter than those with 1980s sires. In general, breed differences for height followed those for weight except that F1 Nellore cows were tallest, which may in part be due to Bos taurus-Bos indicus heterosis for size.     

液相色谱-串联质谱法测定动物尿液中11种β-受体激动剂残留量的不确定度评估

Granulocyte isolation from whole blood of goat, sheep, cattle, horse, dog, pig, and man

A simple two step procedure for the isolation of caprine, ovine, bovine, equine, canine, porcine and human peripheral blood granulocytes is described. After enrichment of granulocytes by centrifugation, contaminating erythrocytes are lysed hypotonically. Recovery, purity, and viability of the granulocyte suspensions are determined. FACScan analysis of the cell suspensions measuring cellular size by forward and sideward light scatter is compared with the corresponding analysis of whole blood leukocytes. Constituencies of the isolated cell suspensions and loss of granulocyte subpopulations through isolation procedure is discussed with regard to granulocyte function assays.
