BACKGROUND Treatment of subclinical mastitis during lactation can have both direct (individual animal level) and indirect (population level) effects. With a few exceptions, prior research has focused on evaluating the direct effects of mastitis treatment, and to date no controlled field trials have been conducted to test whether beneficial indirect effects of lactation treatment strategies targ...

Mastitis is an inflammatory reaction of the udder tissue which is caused by the bacterial infection. Bovine mastitis is one of the devastating disease causing huge loss to the dairy industry worldwide. The present study investigated the current status of clinical and subclinical mastitis among dairy cattle in Dharwad district, Karnataka. The prevalence of mastitis was assessed by surf field mas...

Mammary gland quarters of 139 lactating dairy cows from small-scale dairy herds were examined visually and by palpation for teat lesions and by California mastitis test (CMT) and bacterial culture for subclinical mastitis. Teat lesions were observed in 97 teats. These included teat chaps (39.2%), teat papillomas (23.7%), teat erosions (22.7%), teat fistulae (5.1%), inverted teats (5.1%) and blo...

KEY TAKE HOME POINTS 1. The purpose of dry cow therapy is both therapeutic and prophylactic; selective DCT is aimed only at therapeutic aims 2. Cows that maintain persistent subclinical infections across the dry period are at greater risk of subclinical and clinical mastitis and reduced milk yield during the subsequent lactation 3. Few mastitis pathogens are resistant to most antimicrobials use...

How Much Does Mastitis Cost You? The only way this question can be answered is to know how much mastitis is in your herd. Mastitis robs you in many ways: reduced milk production; treatment cost; discarded milk; death and premature culling; decreased genetic advancement; and reduced milk quality. Reduced milk production accounts for approximately 70% of the total loss associated with mastitis. U...

Subclinical mastitis is a disease of major economic importance to dairy industry causing reduced milk quality and loss in its production. Therefore, the present study was carried out for isolation and identification the main pathogen responsible for this disease and detection the drug of choice. A total of 475 milk samples of lactating dairy cows were collected from different localities in El-S...

Sub clinical mastitis is responsible for heavy economic losses throughout the world in dairy sector. The objective of present study was to investigate lactate dehydrogenase (LDH) enzyme activity in milk for detection of subclinical mastitis in buffaloes Milk samples from 60 buffaloes, including 40 subclinical infected and 20 healthy were subjected to the estimation of LDH using a LDH activity a...

The present study was conducted for the comparative evaluation of leukotoxic activities of indigenous Staphylococcus aureus isolates issued from Institute of Microbiology University of Agriculture Faisalabad Pakistan. A total of 200 milk samples 100 each of buffalos (Nili Ravi) and cattle (Sahiwal) with subclinical and clinical mastitis were collected. Staphylococcus aureus isolates recovered w...

In this review of the literature, mastitis-causing coagulase-negative staphylococci (CNS) and Staphylococcus aureus are compared. Staphylococci are the bacteria most commonly isolated from bovine mastitis, and CNS are now predominant over S. aureus in most countries. CNS include various species, but only a few prevail in bovine mastitis. S. aureus can cause clinical mastitis, but often causes s...

Incidence of subclincial mastitis (SCM) among crossbred cattle from organized dairy farms was studied. The quarter-wise and animal-wise incidence of SCM was 15.62 and 43.33 per cent, respectively. Maximum number of animals (74.36 %) were having one quarter infection. Right-hind quarters were having higher incidence (38.18%) compared with other quarters. The incidence of SCM was lowest during fi...
