Epidemiological Study of Udder and Teat Diseases in Dairy Cows
An epidemiologic study was conducted on 581 dairy cows (indigenous and its crosses 371, exotic crosses 210) of 4 government establishments to find prevalence of udder and teat diseases and their association with udder and teat characteristic, milk yield and milk flow rate in dairy cows. Mastitis (25.5%) was most common disease followed by udder skin diseases (15.0%) and teat diseases (12.6%). P...
متن کاملAffections of Teat and Udder in Dairy Animals
Teat and udder affections are common in domestic animals. Early diagnosis and treatment of diseases of teat and udder is very important for maintenance of their health. Anatomy The udder of the cow and buffalo have four quarters each of which is a separate unit. Each quarter is an independent compartment. Affection of one quarter does not necessitate the involvement of the other quarters. In bu...
متن کاملShort communication: Effect of automatic postmilking teat disinfection and cluster flushing on the milking work routine.
The importance of a consistent and comprehensive milking routine as a critical component of any mastitis control program is well documented. However, as pressure on time increases, farmers are faced with 3 options: (1) adjust the milking routine to suit the time available, (2) undertake the task less thoroughly, or (3) examine which elements of the milking routine can be automated and substitut...
متن کاملRole of neutrophils in protection of udder from infection in high yielding dairy cows
Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in thegland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclearneutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.Most researchers now accept that the PMN is a key factor in the cows’ defense against intrama...
متن کاملEffects of an automatic postmilking teat dipping system on new intramammary infections and iodine in milk.
A technology of automatically applying a postmilking teat dip via the milking machine prior to machine detachment was compared to manual postmilking teat dipping with a teat dip cup for effects on new IMI and iodine content in milk. One hundred twenty Holstein cows were experimentally challenged in a 22-wk trial with Streptococcus agalactiae and Staphylococcus aureus and 148 Holstein cows were ...
