AbstractObjective: This current study was done to find any correlation between clinical mastitis and lameness occurrence and incidence in dairy farms.Design: This prospective field trial was done on a case control study basis. Cows were divided into two mastitis and control group and lameness recorded and compared in both groups.Procedures: This current study was done during 9...

The objective of this study was to determine the relationships among daughter clinical mastitis during first and second lactations and sire transmitting abilities for somatic cell score, udder type traits, productive life, and protein yield. Data on clinical mastitis during first lactation were available for 1795 daughters (in six Pennsylvania herds, one Minnesota herd, and one Nebraska herd) o...

Introduction Mastitis is the most frequent and costly disease of dairy cattle. Losses due to mastitis occur for both subclinical and clinical disease. Losses caused by clinical mastitis are often apparent and consist of discarded milk, transient reductions in milk yield and premature culling (Fetrow, 2000). Perceived financial losses for clinical mastitis vary widely. In 2002-2003, farmers part...

The relationship between initial Somatic Cell Count (SCC) and time to first clinical mastitis was estimated from data including 20,422 Holstein heifers, without clinical signs of mastitis during the first month of lactation and with a first test day SCC lower than 400,000 cells /ml. Number of days from 35 days after first calving to first clinical mastitis event in first or second lactation was...

Bovine mastitis, which is an inflammation of the mammary gland frequently resulting from bacterial infection, causes the majority of economic losses to the dairy producers. The prevalence of mastitis in dairy cattle is relatively high. Bovine mastitis can be classified based on clinical futures as clinical or subclinical. Both forms produce significant economic losses due to rejected milk, degr...

Mastitis continues to be the most costly disease of dairy animals. Field surveys of major livestock diseases in Pakistan have ranked mastitis as number one disease of dairy animals (Cady et al., 1983; Khan et al., 1991). In Nili-Ravi buffaloes, mastitis shortens lactation period of each animal by 57 days on an average and reduces 438 kg of milk per lactation (Cady et al., 1983). In addition, ma...

Mastitis is an economic problem. As with many other cattle diseases, the economic damage of mastitis, either clinical or sub-clinical, can be brought down to a few categories: milk production losses, drugs, discarded milk, veterinarian, labour, milk quality, culling, clinical mastitis, sub-clinical mastitis and other diseases. Management decisions can be taken at various levels: the quarter lev...

BACKGROUND Objectives of the study were to document the impact of some management factors on the occurrence of clinical mastitis in primiparous dairy cows and to identify common udder pathogens of clinical mastitis in freshly calved heifers and multiparous cows on the day of calving. METHODS A one-year study was conducted during 2004 and 2005 in 11 selected Estonian dairy herds. Data consiste...

Sire genetic evaluations for protein yield, somatic cell score (SCS), productive life, and udder type traits from the US were correlated with sire evaluations for udder health from Denmark and Sweden and then the correlations were adjusted for accuracies to approximate genetic correlations. Traits from Denmark and Sweden included somatic cell count (SCC) and clinical mastitis from single-trait ...

The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. I...
