Data from the National Mastitis Council (1987) show that 6% of the [udder] quarters in a herd could be expected to be infected in a herd with a bulk tank SCC of 200,000. At 500,000 SCC, 16% of the quarters may be infected with a 6% reduction in milk production compared to a SCC of 200,000.
When used, horses must be placed in an area free of sunlight exposure, drafts, or other sources of outside heat, and hair length should be uniform in the area imaged. Benefits include non-invasiveness and the potential for early identification [ 54 ] of injury, and detection of early contralateral limb injury in the case of orthopedic patients.
Superior check ligament desmotomy is also used in cases of superficial digital flexor tendinitis in racehorses and upper level performance horses, if the tendinitis is recurrent, diffuse, or when the core lesion is >10% of the tendon cross-sectional area. [128] It may be used in conjunction with tendon splitting and annular ligament desmotomy.
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.
After the incision has healed adequately, the horse is turned out in a small area for another 2–3 months, and light exercise is added to improve the tone and strength of the abdominal musculature. Weight loss of 75–100 pounds is common after colic surgery, secondary to the decreased function of the gastrointestinal tract and from muscle ...
Nearly all-white coat at birth, blue eyes, DNA testing, observation for colic, no meconium, pain: Differential diagnosis: Heterozygotes have no known health issues related to the frame allele. Cremello, Dominant white and Sabino-white are normal white or near-white coat colors for healthy horses. Can be distinguished by genetic testing.
Contagious equine metritis (CEM) is a type of metritis (uterine inflammation) in horses that is caused by a sexually transmitted infection. It is thus an equine venereal disease of the genital tract of horses, brought on by the Taylorella equigenitalis bacteria and spread through sexual contact. The disease was first reported in 1977, and has ...
Equine nutritionists and management specialists also recommend a grassless area, which they sometimes call a "sacrifice area," be fenced off from pastures intended for forage where horses can be placed when it is wet or muddy, to prevent the grass from being trampled, and during times of drought, to prevent or minimize overgrazing.
