Maintaining healthy herds is a priority in commercial dairies. Prevention, early diagnosis, and effective treatment of health disorders is required to improve cow performance and enhance longevity of the animals.
Most of the metabolic problems of the dairy cow happen during the first two weeks of the lactation. It has been reported that nearly 25 percent of the cows that leave the herds do so during the first 60 days in milk.
The installation of automatic milking systems (AMS) is becoming more common around the world, as well as larger herd sizes. Risk factors for mastitis in farms using AMS may be different from farms using conventional milking systems (CMS).
Bovine herpesvirus 1 (BOHV-1) is a virus that causes Infectious Bovine Rhinotracheitis (IBR), infectious pustular vulvovaginitis, temporary infertility, embryonic death and abortions in cattle. The virus affects herds around the globe, causing significant economic losses.
Leptospirosis is a disease of global importance caused by the bacterium Leptospira spp. This disease has significant impact on dairy cattle health and production
Multi-dose automatic syringes are used in bovine tuberculosis eradication campaigns for inoculating intradermal injections of purified protein derivatives (tuberculin). One of these is the McLintock syringe, which is widely used in Europe
cute puerperal metritis is an acute systemic illness whose main clinical symptoms are fever and signs of toxemia due to an infection of the uterus.
Mycobacterium avium paratuberculosis (MAP) is a bacteria that infects dairy cattle (and other ruminants) causing paratuberculosis or Johne’s disease. This disease leads to production losses in dairies all over the world.
Foot-and-mouth disease (FMD) is a severe, highly contagious viral disease caused by an Aphthovirus that spreads quickly and produces significant economic losses in the cattle industry. The virus is found in all excretions and secretions from infected animals…
Ruminal acidosis results from an excessive acid load in the rumen not neutralized by salivary or feed buffers. Cows susceptible to both subacute (SARA) and acute ruminal acidosis change their metabolism, eating behavior, and production performance.
Gastrointestinal nematodes like Cooperia oncophora and Ostertagia ostertagi are widely prevalent in dairy cattle. Nematodes cause production losses through reduction in intake, growth, milk production, and mortality in heavily parasitized animals.
Fungal species of Fusarium produce the mycotoxins deoxynivalenol, fumonisins, and zearalenone. The limits established for dairy cattle by the Food and Drug Administration (FDA) in the US for deoxynivalenol and fumonisin are 5 ppm and 30 ppm, respectively. Although the FDA does not suggest safety guidelines for zearalenone, the European Commission established 250 ppb as the maximum legal limit in complete feed for this mycotoxin.
