The objective was to assess the prevalence and influence of clinical subclinical mastitis during service period cows in a herd Tarumirim (MG), from October 2019 May 2020. Around 65 Gir x Holstein Guzerá lactating crossbred were evaluated. Subclinical diagnosed by means California Mastitis Test (CMT), mastitis, strip cup test animals’ signs. Pregnancy after calving rectal palpation method, with ...

A study was carried out to assess the therapeutic effect of ascorbic acid in mastitis of dairy cows. The herd with a population of 250-275 lactating cows was screened for clinical and subclinical mastitis for a period of 5 months. Based on inclusion and exclusion criteria, eighteen animals each with clinical and subclinical mastitis in one quarter only were selected as study population. Twelve ...

Aim: This study was conducted to evaluate the concentrations of sodium (Na+) and potassium (K+) ions in milk of lactating dairy cows with and without subclinical mastitis as putative indicators for detecting subclinical mastitis in dairy cows. Materials and Methods: Thirty seven lactating dairy cows were screened for the evidence of subclinical mastitis using California mastitis test (CMT). The...

Mastitis continues to be a problem for dairymen across the US. Clinical mastitis causes economic loss due to treatment costs, lost quarters, perhaps dying cows and most importantly, discarded milk. Subclinical mastitis on the other hand, silently redu ces milk production and quality until detected with a somatic cell count. It is easy to forget the basics in our attempts to solve a mastitis pro...

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...

This study was conducted to investigate the prevalence of subclinical mastitis caused by Staphylococcus spp. in ewes in West-Azerbaijan province of Iran. Molecular characterization of isolated Staphylococcus spp. from diseased ewes were performed using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) and DNA sequencing of glyceraldehyde-3-phosphate deh...

Mastitis is probably the most important health disorder on dairy farms. This is reflected in a relatively high incidence of clinical mastitis and, on many farms a high prevalence of subclinical mastitis. Additionally, mastitis causes the quality of the milk to decrease, resulting in a loss of production and/or a less than optimal product. To this end, the dairy industry faces worldwide penalty ...

Staphylococcus aureus is a major etiological agent of mastitis in ruminants. We report here the genome sequences of two ovine strains that were isolated from gangrenous (strain O11) and subclinical (strain O46) ewe mastitis. Both strains belong to the same clonal complex. Despite this close genotypic relationship, the two isolates were shown to reproducibly induce highly divergent types of infe...

streptococcus agalactiae , s. dysgalactiae and s. uberis are gram-positive bacterial pathogens that affect cows in dairy herds. these are considered as the major causes of economic losses of dairy producers without a control program. to reveal the role of these agents in inducing subclinical mastitis in dairy cattle in ahvaz, 100 cmt-positive milk samples and 20 cmt-negative milk samples were c...
