BACKGROUND Although several attempts have been made to control enzootic bovine leukosis (EBL) at the local level, a nationwide control program has not been implemented in Japan, except for passive surveillance. Effective control of EBL requires that the transmission routes of bovine leukemia virus (BLV) infection should be identified and intercepted based on scientific evidence. In this cross-s...

Pasture-based dairy production is used widely on family dairy farms in Southern Brazil. This study investigates conventional high input (C-HI), conventional low input (C-LI), and organic low input (O-LI) pasture-based systems and their effects on quantity and quality of the milk produced. We conducted technical site visits and interviews monthly over one year on 24 family farms (n = 8 per type)...

The population of farms using automatic milking systems (AMS) has grown from the first installation a dairy farm in the Netherlands in 1992 to more than 8000 milking units on more than 2400 farms today The vast majority of these farms are in north-western Europe, with the Netherlands having the largest installed base and Scandinavia showing the fastest growth rate in the past few years (Lind, 2...

Swine production in Italy is characteristically oriented towards typical meat products. In 2007, the Italian pig population was more than 9 million head (Italian Pig Breeders Association ANAS, 2008). Pig farms numbered around 101,000 in 2007 and over 80% were concentrated in the four northern Italian regions of Lombardia, Emilia-Romagna, Piemonte and Veneto (ISTAT, 2008). This is why the dairy ...

Mastitis is probably the most important health disorder on dairy farms. This is reflected in a relatively high incidence of clinical mastitis and, on many farms a high prevalence of subclinical mastitis. Additionally, mastitis causes the quality of the milk to decrease, resulting in a loss of production and/or a less than optimal product. To this end, the dairy industry faces worldwide penalty ...

This paper compares management of mastitis on organic dairy farms with that on conventional dairy farms. National standards for organic production vary by country. In the United States, usage of antimicrobials to treat dairy cattle results in permanent loss of organic status of the animal, effectively limiting treatment choices for animals experiencing bacterial diseases. There are no products ...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

abstract the industrial dairy farms in iran are facing several economic problems and about six percent of these farms were shut down in fars province due to low profitability. despite such problems and availability of other enterprises in the region, farmers do not switch to other farm activities. in this context, the factors affecting acceptance of diversification options were investigated in ...

This study to document the prevalence and some epidemiological features of gastrointestinal impaction in cattle and buffaloes was conducted by undertaking key informant interview (interviews of farmers and visits to dairy farms), case study analysis (observation of cases registered under randomly selected state veterinary hospitals and polyclinics) and retrospective study in various parts of Pu...

On dairy farms in hot climates worldwide, cows suffer from heat stress, which is alleviated by the use of water cooling systems. Sprinklers and showerheads are known to support the development of microbial biofilms, which can be a source of infection by pathogenic microorganisms. The aim of this study was to investigate the presence of microbial biofilms in dairy cooling systems, and to analyze...
