陈山红心杉杂交授粉种子品质分析报告

对2011年进行的陈山红心杉杂交试验种子进行室内品质测定,结果表明,不同杂交组合间种子千粒重和发芽率均存在极显著差异。杂交组合种子千粒重和发芽率的变异幅度分别为4.35～7.65 g和26.0%～72.0%,平均值分别为5.93 g和48.6%。初步筛选出千粒重和发芽率两个指标均高于均值的杂交组合12个,分别为组合1、2、8、11、12、14、17、20、23、24、42、45,且组合11、42、45千粒重和发芽率高于陈山红心杉二代种子园种子。筛选出的12个杂交组合种子千粒重和发芽率平均值分别为6.96 g和58.5%。     

出口水产品中微生物污染调查分析及限量探讨

为了解出口水产品中微生物污染状况,并为制定微生物限量标准提供依据。采用GB/T 4789—2010的微生物检测方法,检测待出口水产品中菌落总数、大肠菌群、大肠杆菌、沙门氏菌及金黄色葡萄球菌,并与国内外微生物限量标准进行比较。结果显示,374份检测样品中均未检出大肠杆菌及沙门氏菌;金黄色葡萄球菌的总检出率为1.87%;菌落总数基本符合标准,达标比例分别为:鱼制品93.3%,冷冻鱼类96.36%,虾类100%,软体动物85%,饭食类88.89%;大肠菌群为主要污染菌,上述种类符合标准的比例分别为:58.53%,77.38%,72.73%,45%,100%。

Good animal welfare makes economic sense: potential of pig abattoir meat inspection as a welfare surveillance tool

ABSTRACT: During abattoir meat inspection pig carcasses are partially or fully condemned upon detection of disease that poses a risk to public health or welfare conditions that cause animal suffering e.g. fractures. This incurs direct financial losses to producers and processors. Other health and welfare-related conditions may not result in condemnation but can necessitate 'trimming' of the carcass e.g. bruising, and result in financial losses to the processor. Since animal health is a component of animal welfare these represent a clear link between suboptimal pig welfare and financial losses to the pig industry.Meat inspection data can be used to inform herd health programmes, thereby reducing the risk of injury and disease and improving production efficiency. Furthermore, meat inspection has the potential to contribute to surveillance of animal welfare. Such data could contribute to reduced losses to producers and processors through lower rates of carcass condemnations, trimming and downgrading in conjunction with higher pig welfare standards on farm. Currently meat inspection data are under-utilised in the EU, even as a means of informing herd health programmes. This includes the island of Ireland but particularly the Republic.This review describes the current situation with regard to meat inspection regulation, method, data capture and utilisation across the EU, with special reference to the island of Ireland. It also describes the financial losses arising from poor animal welfare (and health) on farms. This review seeks to contribute to efforts to evaluate the role of meat inspection as a surveillance tool for animal welfare on-farm, using pigs as a case example.     

Fluorescein angiography of the canine ocular fundus in ketamine-xylazine anesthesia

Fluorescein fundus angiography was performed on 30 dogs with no pathologic fundus findings using a Canon CF 60 Z wide angle camera. In serial photography of the dye passage 4 different circulatory phases could be distinguished: choroidal, retinal anteriolar, capillary and venous phase. The dye passage in the retinal vessels was described in detail. For aesthesia the combination of ketamine and xylazine proved to be suitable.
