农村小规模猪场常见问题与改进措施

近二年，由于市场猪价上涨，养猪利润增大，养殖业蓬勃发展，我镇年出栏300头以内的小规模户就有100多户，还有继续发展趋势，这是一件好事。但也存在诸多问题，使一些养殖户出现亏损。现就小规模猪场常见问题与改进措施，浅谈个人的意见。     

河南省中小规模猪场防疫存在问题调查及原因分析

河南省是养猪大省,养猪业在全国占有举足轻重的地位。2006年1月2日新华网报道：生猪饲养量首次突破1亿头,居全国第三位。养猪业已成为该省畜牧业经济增长中最具活力、发展速度最快的产业。但是近年来,猪病的形势较为严峻,给养猪业造成了很大损失,同时也对养殖户、防疫部门发出了挑战。基于此,作者针对该省中小规模猪场防疫状况做了问卷调查,并根据分析结果,提出相应的建议。     

中小规模猪场种猪的选留与培育

我国目前养猪业的现状,是中小规模养猪场占主体地位,据统计,到2007年末,小规模饲养场户生猪存栏量仍占全国总存栏猪只数量的50%.     

浅谈小规模猪场疫病防控与净化的综合措施

随着经济社会的发展,科技水平的进步,生猪养殖的效益进一步显现,尤其是在近年来国家惠农扶持政策下的带动下,涌现出了一批改建、扩建、新建生猪标准化规模养殖场,生猪规模化养殖比重不断提高。但在生猪规模饲养中,饲养集中,养殖密度大,一旦发生疫情,控制和扑灭的难度较大,将会造成很大的损失。     

小规模猪场管理的盲点

(一)饲料使用的盲点 当前,在小规模养猪场,在饲料的使用上仍存在达很多的盲点.这些盲点的存在,降低了饲料的转化率,影响养猪业的健康发展.主要表现在: 1.催肥阶段提高蛋白,全然不顾高成本.     

影响猪场免疫失败的原因分析

随着我国养猪业的飞速发展,规模化猪场的免疫失败问题日益严重。免疫失败(Vaccinationfailure)就是进行了免疫,但猪群或猪只不能获得抵抗感染的足够保护力,仍然发生相应的亚临床型疾病、甚至临床型疾病。免疫后猪群或猪只抗体水平或细胞免疫水平不能达标,保持持续性感染带毒状态,都属于     

猪场免疫失败的原因与改进措施

近年来，由于多方面的原因，猪场疫病趋于复杂化，养猪业疫病控制面临着严峻的挑战，猪场一般采用加强饲养管理、免疫注射、药物保健等措施预防猪场疾病的发生。但由于免疫失败导致猪群的发病率上升的现象在猪场经常发生，给养猪业造成严重的经济损失。以下就猪场免疫失败的原因及改进措施作一简要探讨。[第一段]     

规模猪场防疫中存在的问题与对策

近年来,随着上海市产业结构调整,城市化进程加快,上海市养猪生产的规模化、集约化程度越来越高,郊区规模化猪场基本实现了良种猪生产。但由于传统的饲养理念还根深蒂固,防疫观念落后,缺少现代的管理方式和手段,导致猪场疫病经常此起彼伏,给我市的养猪业带来较大损失,同时也给本

Farm-level factors associated with above-average production on pig farms in Evia, Greece

The aim of this study was to identify farm-level factors associated with above-average production of pig farms in Evia, Greece. Cross-sectional data on pig farm characteristics and management, farmer characteristics, worming practices, anthelmintics used, and the parasite loads of 10 randomly selected boars, sows, weaners, and fatteners were collected from 28 pig enterprises in the Evian region of Greece (74% of the total number of pig enterprises in this region). Above-average productivity was defined as weaning 18 or more piglets per sow per year. A multivariate logistic regression model found that employing immigrant workers reduced the odds of a farm being an above-average producer (OR 0.016, 95% CI 0.001–0.27), while having a veterinarian select the anthelmintic strategy significantly increased the odds of a farm being an above-average producer (OR 10.24, 95% CI 0.78–135.13). None of the gastrointestinal parasites under investigation were significantly associated with above-average productivity. It is concluded that despite the fact that endoparasite load was not significantly associated with above-average production, a quantification of the impact of intestinal worms on pig productivity is needed to know how much control can be envisaged for gastrointestinal worms before reaching the threshold at which it is no longer physically or financially reasonable to continue pursuing control.     

我省中小型猪场的生存空间

Prevalence and some risk factors associated with trichinellosis in backyard pig farms in Zaria, Nigeria

The aim of this study was to determine the presence of trichinellosis in backyard-farmed pigs and the risk factors associated with the infection in Zaria, Kaduna State. Serum samples were collected from 120 pigs selected at random from 50 small backyard farms, and the presence of Trichinella spp. antibodies was determined using a commercially available enzyme-linked immunosorbent assay (ELISA) kit. Data on farm management practices from the farms were obtained through the use of a structured questionnaire. The overall seroprevalence of Trichinella spp.-specific antibodies was 40 % (48/120) by ELISA. All the extensive farms sampled had at least one Trichinella-positive animal. The age and sex of the animals were not significantly (p?>?0.05) associated with the infection; however, the management systems, presence of rodents, rodent control, and access to dead pigs showed significant (p?<?0.05) association with Trichinella spp.-infected pigs on the farm. In conclusion, there was a high prevalence of antibodies to trichinellosis in backyard raised pigs in Zaria, and intensive pig farming with the adoption of proper biosecurity measures is advocated to prevent the transmission and spread of trichinellosis.     

禽肉风味影响因素研究进展

风味是味觉、嗅觉和三叉神经等感觉系统对食物刺激而产生的感觉效应(Spanier et al,1993).食物中的水溶性成分与口腔味蕾上的受体相互作用产生味觉(Johnsen et el,1991).甜、酸、苦、咸是人类所能感觉的最基本味道,但鲜味也被认为是第五种基本味道(Brand et al,1994).嗅觉是食物中的挥发性物质刺激鼻腔嗅觉神经而在中枢神经引起的感觉.三叉神经依赖于眼、鼻和口中的神经末梢,可接受冷、热、辣、涩等味感(Johnsen et el,1991).     

加强猪场生物安全管理确保养猪生产顺利发展

我国是养猪生产大国,生猪饲养量和年出栏量均居世界首位.改革开放以来,养猪业持续稳定发展,特别是近年来,生猪饲养的集约化、规模化和专业化程度不断提高,猪病防控水平也突飞猛进.但随着饲养环境的恶化和疾病的复杂化,给猪病的整体预防带来较大的困难,使养猪业发展受到一定制约,也带来严重的经济损失和其他社会、政治问题.     

Risk factors of contamination of pig farms in the Netherlands with pig diseases and agents thereof: a review of the literature

Part of the project 'Clean pigs' an extensive study of literature was made of the risk factors related to the introduction of pathogenic micro-organisms in pigfarms in the Netherlands. On the basis of this study of literature and in close cooperation with the experts of the steering group of the project 'Clean pigs' a number of risk factors relevant for the Dutch pig farming were estimated. The impact of these risk factors on the introduction of the most important pig diseases/-agents in Dutch pig farming was quantified for three different levels of preventive measures. It is shown that many risks can be reduced or even be neglected by the biosecurity measures already applied on pig farms. For most diseases, including list A and B diseases of the OIE list, introduction of new animals is regarded as the main risk factor, but this risk can be reduced in several ways. Besides this, aerogenic transmission and introduction by rodents and pet animals need the most attention. Through specific actions and measures several important risk factors can be diminished or even eliminated.
