Proliferative osteitis of the femoral greater trochanter and humeral medial epicondyle as a cause of lameness in sows.

Thirteen chronically lame female breeding pigs were examined clinically and post mortem. Of the eight sows with hindleg lameness, one showed detachment of the ischial tuberosity and a second showed detachment of the ischial tuberosity on the left and a mid-shaft femoral fracture on the right. Two showed no lesions apart from a change in the positional relationship between the femoral head and the greater trochanter, resulting in a lowering of the femoral head. In the remaining four sows an apparently unreported condition was seen, which produced a proliferative osteitis of the greater trochanter. All five animals lame in the forelimb showed varying degrees of proliferative osteitis of the medial epicondyle of the humerus. Advanced cases could be palpated in the live animal. It is proposed that proliferative osteitis may be a response, at the point of attachment of the muscle masses of the major limbs, to the trauma of over exertion.

Effect of premilking teat disinfection on mastitis incidence, total bacterial count, cell count and milk yield in three dairy herds.

An iodophor teat disinfectant was applied before milking by dip or spray to 50 cows and 50 cows were left untreated in each of three commercial herds. The mean incidence of clinical mastitis was reduced by 57 per cent, the total bacterial count by 70 per cent and the count of thermoduric organisms by 32 per cent. These results were not statistically significant, except that one herd showed a significant decrease in total bacterial count. There was no effect on somatic cell count, milk production or milk iodine residues. Atmospheric iodine concentrations increased in the two herds which applied the treatment as a spray, but the levels attained were not likely to be detrimental to human health.

A simple treatment for heel abscesses and deeper foot infections in cattle.

A simple technique for the treatment of deep navicular and pedal joint infections in cattle is described. Under regional or local anaesthesia, a hoof-knife is inserted into the full depth of the discharging sinus and a large drainage area is created. A wooden block is glued to the sound claw and parenteral antibiotics are administered for four to six days. Of 64 cows treated between March 1986 and June 1989, 55 (86 per cent) recovered. The causes of failure and comparisons with other treatments are discussed.

Digital dermatitis in dairy cattle.

A condition of digital dermatitis causing lameness in a dairy herd is described. The lesion was a small circumscribed area of epidermal inflammation in the skin immediately above the coronet between the bulbs of the heel. Topical treatment, consisting of excoriation and application of a gentian violet and tetracycline aerosol spray, was effective. Although the high incidence and rapid onset of the condition suggested an infectious cause, no organism was isolated consistently.
