Associations between biosecurity and outbreaks of canine distemper on Danish mink farms in 2012–2013
BACKGROUND During 8 months from July 2012 to February 2013, a major outbreak of canine distemper involving 64 mink farms occurred on the Danish peninsula of Jutland. The canine distemper outbreak was associated with exposure of farmed mink to infected wild carnivores and could represent a deficit in biosecurity on the mink farms. The aim of this study was to investigate the extent and associati...
A 1:1 matched case-control study of calves under 1 month of age was carried out by weekly visits to 7 dairy farms in Mashhad from May 2008 to October 2008. Fecal samples were collected from a total of 112 calves with clinical signs of diarrhea and from 112 matched animals without clinical signs of diarrhea as assessed by a scoring system. The samples were investigated for the presence of Rotavi...
Respiratory disorders are major concern for dairy cattle industry. Viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. The most important viral agents arebovine viral diarrhoea virus (BVDV), bovine herpes virus type 1 (BHV-1), bovine respiratory syncytial virus(BRSV), parainfluenza virus type 3 (PIV-3) and bovine adenovirus (BAV). This cros...
A model for availability growth is developed to capture the effect of systemic risk prior to construction of a complex system. The model has been motivated by new generation offshore wind farms where investment decisions need to be taken before test and operational data are available. We develop a generic model to capture the systemic risks arising from innovation in evolutionary system designs...
During large Q fever outbreaks in the Netherlands between 2007 and 2010, dairy goat farms were implicated as the primary source of human Q fever. The transmission of Coxiella burnetii to humans is thought to occur primarily via aerosols, although available data on C. burnetii in aerosols and other environmental matrices are limited. During the outbreak of 2009, 19 dairy goat farms and one dairy...
In the past decade wind-based electricity generation has grown rapidly, and is likely to grow even more in the future. Since generation sites—wind farms—tend to be remote, they require transmission lines to transport electricity to markets. These wind farms can be augmented by co-locating them with an electricity storage facility, for example, an industrial battery. This storage facility enable...
Background and Aim: Salmonellosis is one of the most common digestive diseases in the world. Salmonellosis is caused by varieties of salmonella serotypes and there are concerns about the contamination of poultry and its products by this microorganism. Given that the carcasses of poultry, as a major source of infection with this microorganism, determine the frequency and the rate of this type of...
Introduction: Contamination of foodstuffs with fungi and the toxins produced by them is a very important problem in human and animal feeding. In most villages around Shiraz, in small-scale dairy farms, dry leftover bread which is mostly contaminated with fungi is used as a part of food ration for animals. The thin-layer chromatographic method which was used for determination of aflatoxin. Inges...
1. SMART FARMS SET PERFORMANCE GOALS There is an old saying that you can’t get to your destination unless you know where you are going. Many farms that start on the path to milking excellence don’t make it because they don’t have clear quality goals for their farms. Many dairy farms consistently produce high quality milk. In 1998, over 1,800 Wisconsin dairy farms had average bulk tank somatic c...
The constraints that cooperative and non-cooperative dairy farms face in expanding milk production have been reported based on a field study on some cooperative and non-cooperative dairy farms in the state of West Bengal. The study has shown that non-cooperative farms face major constraints and high severity compared with cooperative farms in expanding milk production. Also important is that mo...
