Use of Dry Cow Therapy and Teat Seal in Managing Mastitis in Bred Holstein Heifers
نویسندگان
چکیده
Because of the importance of bred heifers to the future milk production of any dairy operation, it is critical that udder health be maximized to ensure that animals freshen free of intramammary infection (IMI). During the heifer’s first gestation, the presence of mastitis can compromise the development of milk-producing tissues, and in the case of Staphylococcus aureus, milk yield may be reduced up to 10% over the first lactation (Nickerson, 2009; Owens, 1991). Milk quality is also reduced due to an increase in the somatic cell count (SCC) for the duration of the lactation (Paradis et al., 2010). In some of the worst cases, mammary tissue is replaced with scar tissue, causing the heifer to calve with a blind or nonfunctional quarter.

Mastitis control in bred heifers: Use of dry cow therapy and teat sealant for curing existing intramammary infections and preventing new ones
Presence of mastitis in pregnant as well as unbred dairy heifers can adversely affect the development of milk-producing tissues, leading to less than maximal milk production and increased SCC during their first lactation. Use of nonlactating cow therapy or teat sealants have been beneficial in curing existing IMI and preventing new IMI from developing. When used together, the combination of the...

: Dry cow antibiotic therapy is used to eliminate existing intramammary infections and to prevent new infections in the dry period. It is implemented as part of a total management system known as the 'Five-Point Plan' for mastitis control. Recent public concerns over the widespread prophylactic use of antibiotics, coupled with an increasing interest in organic farming, have lead to a re-evaluat...

: Public concerns over the widespread prophylactic use of antibiotics have led to a search for alternatives to dry cow therapy for the prevention of intramammary infections. A popular alternative is to infuse a teat seal at drying-off. The teat seal is a viscous non-antibiotic formulation and when it is infused into the teat canal and the teat sinus it forms an internal seal that provides a phy...

Mastitis in dry cows has traditionally been controlled with long-acting intramammary antibiotic formulations. However, the widespread use of antibiotics, particularly for prophylactic application, is likely to be restricted in the future. As a consequence, there is now a growing requirement for effective alternatives to prevent mastitis. A bismuth-based, intramammary teat seal has recently been...
