浅谈对畜禽养殖场的消毒

近年来,各地畜禽养殖业得到迅猛发展,取得了显著的社会效益和经济效益。众所周知,随着畜禽养殖业规模化、集约化程度的提高,畜禽养殖场疫病控制已成为养殖成败的关键。如何预防、控制和扑灭疫病,做好消毒净化工作是重点。做好消毒工作,可以提高安全系数,及时把疫病堵在门外,以及控制或扑灭疫病,保障畜禽养殖业蓬勃发展。日常工作中,有畜禽养殖场或专业户反映,他们经常做消毒工作,但效果却很差。笔者认为,行业内不少生产经营者对消毒的基本常识不清楚,往往是盲目跟从或模仿,不能进行科学消毒,致使消毒的效果不理想。如消毒效果可受消毒剂的选…

An assessment of external biosecurity on southern Ontario swine farms and its application to surveillance on a geographic level

Risk-based surveillance is becoming increasingly important in the veterinary and public health fields. It serves as a means of increasing surveillance sensitivity and improving cost-effectiveness in an increasingly resource-limited environment. Our approach for developing a tool for the risk-based geographical surveillance of contagious diseases of swine incorporates information about animal density and external biosecurity practices within swine herds in southern Ontario. The objectives of this study were to group the sample of herds into discrete biosecurity groups, to develop a map of southern Ontario that can be used as a tool in the risk-based geographical surveillance of contagious swine diseases, and to identify significant predictors of biosecurity group membership. A subset of external biosecurity variables was selected for 2-step cluster analysis and latent class analysis (LCA). It was determined that 4 was the best number of groups to describe the data, using both analytical approaches. The authors named these groups: i) high biosecurity herds that were open with respect to replacement animals; ii) high biosecurity herds that were closed with respect to replacement animals; iii) moderate biosecurity herds; and iv) low biosecurity herds. The risk map was developed using information about the geographic distribution of herds in the biosecurity groups, as well as the density of swine sites and of grower-finisher pigs in the study region. Finally, multinomial logistic regression identified heat production units (HPUs), number of incoming pig shipments per month, and herd type as significant predictors of biosecurity group membership. It was concluded that the ability to identify areas of high and low risk for disease may improve the success of surveillance and eradication projects.     

Real-time ultrasonic scanning in sheep: the results of the first year of its application on farms in south-west Scotland

After a two-day period of instruction in the use of a linear real-time ultrasonic scanning machine the results obtained by three operators scanning a variety of types of ewe under different conditions were recorded and compared with the actual lambing results. In the first season an overall accuracy of 95 per cent was achieved for the diagnosis of barren ewes and ewes carrying either one or two or more lambs. However, monitoring the accuracy achieved for the diagnosis of zero, one, two, three or four lambs demonstrated an improvement in expertise with time, the accuracy increasing from below 70 per cent to over 90 per cent. A particular improvement was observed after a comparative session with an experienced operator. Analysis of the figures of accuracy for zero, one, two, three and four lambs highlighted the differences between operators which were less evident if only the results for zero, one or two or more lambs were analysed. These analyses showed that 'newly trained' operators were not at first able to scan successfully. However, after a period of acquaintance with the technique (approximately 500 ewes) and an 'appraisal session' with an expert the accuracy of the operators improved sufficiently to be of commercial value to hill flocks and possibly to low-ground flocks with limited housing.

Virucidal disinfectants and feline viruses

Thirty-five commonly used commercial disinfectants (disinfectants, antiseptics, sanitizers, and detergents) were evaluated for their virucidal activity against three feline viruses; feline viral rhinotracheitis virus (a herpesvirus), feline calicivirus, and feline panleukopenia virus (a parvovirus). Disinfectants were diluted as recommended by the manufacturer and were reacted with virus for 10 minutes at room temperature. Viruses were separated from disinfectants by gel filtration in special centrifuge tubes, and were assayed for infectivity in feline cell cultures. All 22 products tested were virucidal for feline viral rhinotracheitis virus, 11 of 35 were virucidal for feline calicivirus, but only 3 of 27 tested were effective against feline panleukopenia virus. A 0.175% sodium hypochlorite solution was the most effective and practical broad-spectrum virucidal product used alone or in combination with other disinfectants/detergents.
