利用现代信息技术做好生猪产地检疫工作

生猪产地检疫是基层动物卫生监督机构的一项重要工作,是防控重大动物疫病尤其是防止疫病通过运输进行远距离传播的重要措施.然而,由于我国动物防疫体系不完善、队伍不健全,尤其是基层负责产地检疫等业务工作存在人手严重不足、检疫设备落后、交通不便等问题.因此利用现代信息技术做好生猪产地检疫工作,能够解决当前因养猪场位置偏远、人手不...     

制约目前养猪生产的原因及对策调查

养猪生产是我国畜牧业中最大的养殖项目,全世界每年上市肉猪9亿多头,而我国就有近5亿头,其养殖数量和产值均位居世界之首.随着农业产业结构的调整,我国的养猪业又将迎来更大的发展空间,未来养猪业的发展机遇将多于挑战,只要我们正视目前养猪业的现状,认真分析国内外的发展变化,我国的生猪生产前景是光明的.

临海市生猪产业剖析

近几年,浙江省临海市生猪产业起落较大.据调查统计,2006年底,存栏量14.1万头,2007年,生猪存栏量达到16.5万头,出栏量17.5万头.2008年年底,存栏量达到193万头,出栏量达18.3万头.生猪价格波动也较大.毛猪从2006年6月底6.20元/kg的最低谷涨到2007年的19元/kg.而2008年又连续下滑.目前,临海市毛猪价格只有10元/kg,养猪业有可能再次出现滑坡.     

Evaluation of smallholder pig production systems in North Vietnam: Pig production management and pig performances

This study investigated the productive adaptability of pig breeds under different smallholder production conditions in Vietnam, comparing an indigenous with a Vietnamese improved breed. Fieldwork was conducted in four villages with different remoteness in North Vietnam from 2001 to 2002, in 64 households keeping the improved Mong Cai or indigenous Ban as sow breeds and progeny for fattening. Four visits per farm yielded 234 structured interviews. Reproductive performances were derived from 135 litters. Individual weights of pigs (n = 755) were obtained. Data were analysed by regression, linear and generalised linear, especially loglinear models.

Two distinct pig production systems were identified, that differed in remoteness, market access, resource availability, distribution of pig breeds and pig production intensity. Higher performances of 1.4 and 1.5 litters year^− 1, 8.4 and 8.4 piglets weaned litter^− 1, 66.6 and 93.0 kg piglets weaned sow^− 1 year^− 1, and 136 and 177 g day^− 1 ADG were found in two villages near town with semi-intensive production conditions and a high rate of improved Mong Cai sows and MC and LW × MC offspring in the observed population. Lower performances of 1.1 and 1.1 litters year^− 1, 4.6 and 5.5 piglets weaned litter^− 1, 20.5 and 30.9 kg piglets weaned sow^− 1 year^− 1, and 66 and 85 g day^− 1 ADG were observed in parallel to higher incidences of indigenous Ban pigs away from town under extensive conditions. Total live weight offtake per household per year was higher near town and in one village distant to town. MC and LW × MC remained even under demand-driven conditions below the performance potential reported for improved genotypes. Under resource-driven conditions with a saving-oriented production pattern, the higher-yielding but more demanding Mong Cai might not be an efficient production alternative as a further performance reduction can be assumed. A considerable live weight output was observed under resource-driven conditions and with a higher percentage of crossbred LW × Ban offspring in the population, possibly representing a promising production alternative. Factors influencing the performance expression of pigs, and the suitability of different methods for the assessment of performance parameters on-farm are discussed.

Cystic echinococcosis in the Falkland Islands

From 1991 to 1993, an investigation into the epidemiology of cystic echinococcosis (CE) was carried out in the Falkland Islands to evaluate the progress of the hydatid eradication campaign. The prevalence of CE in sheep was assessed using abattoir and farm slaughter data, and the exposure of dogs to the parasite was estimated using immunological techniques. A total of 59 466 sheep was examined at slaughter for E. granulosus and T. hydatigena cysts and the entire dog population of the Falkland Islands (n = 908) was examined by ELISA for the presence of specific serum antibodies to E. granulosus (IgG, IgA and IgE). In addition, a subsample of dogs (n = 464) was tested for the presence of E. granulosus antigens in faeces (copro-antigens). The prevalence of CE in sheep increased significantly during the period of the study from 0.11% in 1991 to 0.47% in 1993. Nineteen (2.1%) of 908 dog sera tested were seropositive, and eight dogs (1.7%) of 464 tested were positive in the copro-antigen assay. The combined use of abattoir surveillance, specific antibody and copro-antigen assay suggested that there were several locations in the Falkland Islands where the life cycle of E. granulosus may still perpetuate. Specific deficiencies in the eradication effort in those locations could be identified through follow-up questionnaires.     

规模化猪场猪粪中的营养素分析研究

以规模化养猪场中的保育猪、育肥猪和妊娠母猪为试验猪群,分别就各自粪样中的含水率、全氮、全磷、有机质、铜、锌等"营养素"指标,按照国家和环境保护行业检测分析标准方法进行了严格测定,并比较分析了这些指标在不同猪群、不同季节的变化规律。结果表明:(1)夏季猪粪中"营养素"除全氮指标外,其他各指标含量均处于最低状态,含水率、有机质二项指标秋冬季明显高于春夏季;全氮、全磷指标各季节存在明显差异;铜含量秋冬季明显高于夏秋季;锌含量春季最高,夏季最低。(2)保育猪粪样中铜、锌含量最高,育肥猪次之,妊娠母猪最低,相互之间差异极显著,其变化趋势表现为递减规律,含水率、全氮、全磷和有机质在不同猪群之间也有一定的差异。     

大河猪与大河乌猪的肌肉营养成分分析

以中国地方猪种大河猪和以大河猪为母本选育形成的培育品种大河乌猪为研究对象,研究了2个猪种肌肉的氨基酸和脂肪酸组成情况。结果表明:以肉质性状优良闻名于世的大河猪及含有大河猪血缘的大河乌猪肌肉中有丰富的氨基酸含量。其中含量最多的是谷氨酸,2个品种的肌肉中分别达到12.12%和12.32%。含量最少的是蛋氨酸和脯氨酸,2个品种肌肉中蛋氨酸含量分别为1.75%和1.79%,脯氨酸分别为2.54%和2.57%。两品种间各种常见氨基酸的组成差异均不显著(P>0.05)。对肌肉中脂肪酸组成的分析结果表明,2个实验猪种在肌肉中脂肪酸总量、饱和脂肪酸以及不饱和脂肪酸含量等各方面指标都较高,尤其是单不饱和脂肪酸含量的比例较高,这说明其营养价值和食用品质高,也部分解释了中国地方猪种肉脂特性优良的形成原因。
