The results of many studies suggest that cows with SCC of less than 200,000 are not likely to be infected with major mastitis pathogens, but cows with SCC above 300,000 are probably infected (Smith, 1996). Herds with bulk tank SCC above 200,000 will have varying degrees of subclinical mastitis present. Data from the National Mastitis Council ...
The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count of milk. It operates by disrupting the cell membrane of any cells present in the milk sample, allowing the DNA in those cells to react with the test reagent, forming a gel. [1] It provides a useful technique for detecting subclinical cases of mastitis.

Equine drug testing is a form of drug testing applied to performance horses in regulated competition. Most common in racehorses , drug tests are also performed on horses in endurance riding and in international competition such as the Olympics and FEI -sanctioned competition.
[1] The disease appeared to have a genetic component, and, after hereditary diseases known to affect other horse breeds were investigated, it was concluded that this was a newly identified disease. [1] The cause of disease was tracked down using a genome-wide association study, which implicated a region on horse chromosome 25. [1]
Reuse of syringes and needles is a risk factor for transfer of the disease. Currently in the United States, all horses that test positive must be reported to federal authorities by the testing laboratory. EIA-positive horses are infected for life. Options for the horse include sending the horse to a recognized research facility, branding the ...
Horses with the acute form of colic usually have a duration of colic less than 24 hours long, while chronic cases have mild but intermittent colic. Horses with the chronic form tend to have better prognosis. Rectal examination reveals a mass at the base of the cecum in 50% of cases. [19]
Grooming is an important part of horse care.Grooming a horse daily allows the handler to check on the horse's general health and well-being. At a minimum, horses are generally groomed before being worked, and are usually groomed and cleaned up after a workout as well. [1]
