猪场

The modes of production,the rules of operation,the structures of system and benefits of ecological agriculture based on utilizing the excrements from the small,medium and large piggeries have been analyzed separately.

剖析了小、中、大3类猪场以沼气建设为纽带发展生态农业的规律、生产模式、系统结构及其效果。

The results in research show that the governments must enhance the management for the excrements from piggeries and formulate the preferential policies for development of the ecological agriculture,and that pigraising families must establish social responsibility of saving the resources and protecting the environment in order to promote development of the ecological agricultures.

结果表明，为了促进规模养猪健康发展，形成&农林渔牧&生态农业体系，养猪专业户必须增强节约资源、保护环境的社会责任感，政府要加强猪场污染物排放的监管，同时制定优惠政策引导和促进猪粪尿资源综合利用。

Odor pollutants can be controlled in the early, middle and late raising-stage in a scaled pig farm. Tests and experiments showed that feed additives contained deodorant microorganisms and other chemical ingredients could reduce ammonia and sulfuretted hydrogen efflux 38.6% and 20.6% in pigsty, and 14.7% and 20.4% in wastewater adjusting tank respectively, meanwhile odor concentration was remarkable reduced 43.8%.

集约化猪场恶臭的生物处理可以在饲养的营养技术、饲养过程和粪便处理阶段分别处理，试验表明使用含有微生物制剂等成分的除臭剂为饲料添加剂，可使猪舍氨气和硫化氢分别降低38.6%和20.6%，调节池中氨气和硫化氢分别降低14.7%和20.4%，臭气浓度降低43.8%。

The pig industry has its own scheme for Salmonella monitoring called the Zoonoses Action Plan.

国家兽医官员也进行疾病的检测，卫生部门主要检查屠宰的猪肉是否有病理变化，猪场也有自己的检测沙门氏菌的方案，他们称之为人畜共患病计划。

Although it would be impractical for most producers to convert their operations to a wet feeding system, the simple act of mounting the water nipple in the farrowing crate directly over the feed hopper can help to stimulate sow feed intakes.

虽然让大多数猪场转变成湿喂操作系统是不现实的，但是简单湿式可直接在产仔箱的料槽里安装乳头饮水器也能刺激母猪采食量。

The epidemiological investigation of piglet was carried out carefully in hoggeries and every towns in north of Anhui Province.

方法］对皖北地区猪场及各乡镇发生猪水肿病进行较详细的流行病学调查。

Between 2002 and 2003, 275 cases were collected from pig farms of Taiwan. The main clinical signs of these cases were tachypnoea, dyspnea, and abdominal respiration.

本研究自台湾地区猪场，於临床呈现呼吸急促、呼吸困难及腹式呼吸等症状之患猪，从2002至2003年共收集275个病例。

From landfills to waste treatment facilities; from stockyards to hog farms, virtually any odor problem can be effectively countered with the high quality fog products.

从堆填区的废物处理设施，从畜栏到猪场，几乎任何气味问题，可以有效地进行高品质的产品反驳雾。

One pair of primers that amplified the gB gene of pseudorabies viruswas designed and synthesized.PCR technique detecting the DNA of PRV was established after selecting the best reaction conditions.This technique was applied to specifically amplify the 281 bp DNA fragment of the PRV strains including Fa,Fb,Bartha,BJ,GD,V2F4,S,S3,SR,Buk,Shope,Norden,Mink Ⅲ,HB,F8,F9 and F12 in cultured samples.The negative results were achieved from Vero cells,swine vesicular disease virus,hog cholera virus,Japanese encephalitis virus,porcine reproductive and respiratory syndrome virus,porcine parvovirus,foot and mouth disease virus F29 strain,O3I3 strain,T509 strain and O Ⅱ MF249 strain.The results of sequencing showed that the PCR method was of specificity.The sensitivity of PCR reached 15.8 pg of PRV Fa strain DNA.The tissue samples obtained during 1994 and 2000 were detected,and the results showed that the sensitivity of PCR was more sensitive than virus isolation and the Sandwich ELISA.The PCR was applied to detect 191 tissue samples from 31 pig farms obtained from Guangdong,Fujian,Hainan Provinces during 1999 and 2000,50 samples(26.2%)were positive and 22 pig farms(71%)were positive.

根据伪狂犬病病毒gB基因的序列，设计并合成了一对引物，以闽A株细胞培养毒为模板，筛选最佳反应条件，建立了检测PRV的PCR方法应用该方法对Fb、Bartha、BJ、GD、V2F4、S、S3、SR、Buk、Shope、Norden、MinkⅢ、HB、F8、F9、F12等毒株的细胞培养液进行基因扩增，均获得了分子量为 2 81bp的特异性目的DNA片段，而对Vero细胞与FMDV、SVDV、HCV、PRRSV、JEV、PPV等病毒进行检测，结果均为阴性，没有出现交叉反应对PRV毒株扩增的产物测序，结果序列与文献报道一致，证明PCR扩增产物和方法的特异性对 1994～ 2 0 0 0年期间送检的临床样品和保存的PRV毒种，用病毒分离、双抗体夹心ELISA和PCR等 3种方法进行检测，结果前 2种方法检测为阳性的，PCR检测均为阳性；PCR检测为阴性，前 2种方法检测也为阴性；可是，前 2种方法检测为阴性的，PCR却检测出部分阳性；经x2 检验，证明PCR检出率明显高于前 2种方法的检出率对PRV闽A株细胞毒提取物DNA进行检测，其最低检出量为 15 8pg 对 1999～ 2 0 0 0年期间广东、福建、海南等省的 31个大中型猪场送检的 191份病料进行检测。

And Hubei indigenous livestock and poultry breeding market has become the first demonstration of the project enterprise.
