辽宁省朝阳市气候变化分析

为了解辽宁省朝阳市的气候变化特征,为该地区的气候资源利用、防灾减灾和决策服务提供科学依据,利用该市国家基准气候站1953—2013年的气象资料,包括年平均气温、年平均最高气温、年平均最低气温、年降水量、年平均风速、年日照时数等气象要素资料,采用一元线性回归法,对该地区近61年的气温、降水、风速及日照时数变化特征进行分析。结果表明,朝阳市1953—2013年的年平均气温、年平均最高气温和年平均最低气温均呈波动上升趋势;该市近61年的年降水量、年平均风速和年日照时数均呈减少趋势。气温的升高和降水的减少,提示辽宁省朝阳市的暖、干气候在逐渐加重。

朝阳市首次应用肉羊胚胎移植技术

目前，辽宁省朝阳市畜牧科技人员与内蒙古畜牧科学院合作，将胚胎移植技术首次应用于朝阳市肉羊规模生产。朝阳市是全国重点的半农半牧区，是辽宁省养羊重点区域，羊饲养量占全省的1/3左右，而近百万只基础母羊，仍然是杯水车薪。朝阳市引进了胚胎移植技术，首次投入12万元资金，采取同期发情和超排技术，成功地实施了胚胎移植260只。这项技术的实施将大大地加快种羊扩繁的速度，加快肉羊改良的步伐。     

Comparison of in vitro and in situ methods in evaluation of forage digestibility in ruminants

The objective of this study was to compare the application of different in vitro and in situ methods in empirical and mechanistic predictions of in vivo OM digestibility (OMD) and their associations to near-infrared reflectance spectroscopy spectra for a variety of forages. Apparent in vivo OMD of silages made from alfalfa (n = 2), corn (n = 9), corn stover (n = 2), grass (n = 11), whole crops of wheat and barley (n = 8) and red clover (n = 7), and fresh alfalfa (n = 1), grass hays (n = 5), and wheat straws (n = 5) had previously been determined in sheep. Concentrations of indigestible NDF (iNDF) in all forage samples were determined by a 288-h ruminal in situ incubation. Gas production of isolated forage NDF was measured by in vitro incubations for 72 h. In vitro pepsin-cellulase OM solubility (OMS) of the forages was determined by a 2-step gravimetric digestion method. Samples were also subjected to a 2-step determination of in vitro OMD based on buffered rumen fluid and pepsin. Further, rumen fluid digestible OM was determined from a single 96-h incubation at 38°C. Digestibility of OM from the in situ and the in vitro incubations was calculated according to published empirical equations, which were either forage specific or general (1 equation for all forages) within method. Indigestible NDF was also used in a mechanistic model to predict OMD. Predictions of OMD were evaluated by residual analysis using the GLM procedure in SAS. In vitro OMS in a general prediction equation of OMD did not display a significant forage-type effect on the residuals (observed - predicted OMD; P = 0.10). Predictions of OMD within forage types were consistent between iNDF and the 2-step in vitro method based on rumen fluid. Root mean square error of OMD was least (0.032) when the prediction was based on a general forage equation of OMS. However, regenerating a simple regression for iNDF by omitting alfalfa and wheat straw reduced the root mean square error of OMD to 0.025. Indigestible NDF in a general forage equation predicted OMD without any bias (P ≥ 0.16), and root mean square error of prediction was smallest among all methods when alfalfa and wheat straw samples were excluded. Our study suggests that compared with the in vitro laboratory methods, iNDF used in forage-specific equations will improve overall predictions of forage in vivo OMD. The in vitro and in situ methods performed equally well in calibrations of iNDF or OMD by near-infrared reflectance spectroscopy.

中国圈养野生动物疫苗使用调查

2005年对中国动物园协会单位中的18家动物园饲养野生动物疫苗免疫情况进行调查。受调查动物园在野生动物疫苗使用和动物种类方面具有一定的代表性。调查结果显示动物园动物现共使用18类36种疫苗,预防31种疫病。其中哺乳动物使用14类24种疫苗,预防24种疫病;禽类使用4类12种疫苗,预防7种疫病。使用范围最广的有禽流感、犬瘟热疫苗等、新城疫疫苗、猫瘟热疫苗等。共有24目58科动物接种疫苗,其中食肉动物类1目8科,食草动物类3目9科,杂食动物类2目3科,禽类18目38科。研究结果提示应加强动物园之间疫病信息交流、防疫资源的利用、疫病监测和研究,加大对动物园动物疫病的研究投入,逐步建立动物园动物统一的防疫规程。     

Estimate of economic impact of fowl cholera in turkeys in Georgia in 1986

Information gathered from cases of fowl cholera (FC) in commercial turkey flocks through case records, flock records, and telephone and mail surveys was used to estimate disease costs. The cost to the Georgia commercial turkey industry in 1986 from preventive measures, treatment of outbreaks, and production losses from the disease was estimated at $634,545. The cost of FC per kg of live production was estimated to be $0.015.     

ELISA试验在防制猪伪狂犬病中的应用

猪伪狂犬病是由伪狂病病毒(Pseudorabies virus PRV)引起的急性传染病。其特征是成年猪常为隐性感染，可有流产、死胎、呼吸系统症状，新生仔猪除神经症状外还可侵害消化系统，并伴大批死亡。本病已经给全世界的养猪业造成严重的损失，我国许多地区已报道该病。为进一步探讨该病的控制、净化措施，我们对12个养猪场共856分血清采用美国嗍公司的ELISA试剂盒进行了抗体检测。     

Use of cyclocryotherapy in management of glaucoma in dogs

In 5 cases of glaucoma (2 from trauma, 2 from narrowed drainage angles, 1 secondary to lens extraction), cyclocryotherapy was used to control intraocular pressure. In all cases the intraocular pressure decreased, with the usual result being a cosmetic and painless but blind eye.     

Occurrence of MRSA in pigs and in humans involved in pig production--preliminary results of a study in the northwest of Germany

In 2007, 678 pigs of all age groups out of 347 different farms from Lower Saxony and Northrhine-Westphalia and 86 persons occupationally exposed to pigs were investigated for their nasal colonisation with methicillin-resistant Staphylococcus areus (MRSA) by the Field Station for Epidemiology of the University of Veterinary Medicine Hannover and the Robert Koch-Institute. At the individual animal level, a frequency of positive results of 13% (n = 85 positive animals) and at the herd level, a frequency of positive results of 18% (n = 62 positive herds) were found. All isolates were assigned to the Multilocus Sequence Typing Type ST398. Within MRSA-positive herds, there were more MRSA-negative than MRSA-positive animals. Among the occupationally exposed persons (veterinarians, laboratory personnel and meat inspection personnel), 20 persons (23%) showed a nasal colonisation with MRSA ST398. A quite strong association between the intensity of the contact to pigs with the frequency of nasal colonisation in the occupationally exposed persons was detected. None of the animals or the humans nasally colonised by MRSA ST398 showed any clinical symptoms of a staphylococcal infection. Conclusions are drawn on the herd and intra-herd prevalence of the nasal colonisation of pigs with MRSA ST398 in pigs, but especially on which questions need to be addressed by further research.     

2017年西藏拉萨市家禽禽流感抗体水平检测

为了解西藏拉萨市家禽禽流感抗体水平,2017年8月随机选择免疫过H5禽流感疫苗的8个规模养殖场、2个散养户、3个活禽交易市场,共13个群体,采集1 041份家禽血清样品进行H5、H7、H9亚型禽流感HI抗体检测。结果显示：H5亚型禽流感免疫抗体合格率为45.73%,H7、H9亚型抗体阳性率分别为21.13%、52.64%;养殖场、散养户和活禽交易市场的不同亚型抗体水平存在较大差异,规模化养殖场的H7亚型抗体阳性率最高（29.92%）,活禽市场的H5、H9亚型阳性率最高（78.16%、79.31%）,散养户的所有亚型抗体阳性率均最低。结果表明,拉萨市H5亚型禽流感疫苗免疫效果较差,特别是散养户,疫病发生风险较高,H7、H9亚型疑似自然感染率较高,应进一步查明原因,及时采取相应的措施,防止疫情发生。
