Enfermidades digitais em vacas de aptidão leiteira: associação com mastite clínica, metrites e aspectos epidemiológicos

With the objective to investigate a possible association between foot diseases, clinical mastitis and/or metritis and predisposing factors for foot diseases, 5300 dairy cows from 80 intensive and semi-intensive farms were used. In 325 (6.13%) cows only foot disease was diagnosed, in 35 (0.66%) foot disease and clinical mastitis, in 52 (0.98%) foot disease and metritis, in 28 (0.53%) foot disease, clinical mastitis and metritis, in 128 (2.42%) only metritis, in 165 (3.11%) only clinical mastitis, and in 89 (1.68%) cows metritis and clinical mastitis. Rapid changes in the diet, high exposure time of hoof horn to slurry and wet conditions, concrete floors, use of footbaths, low frequency of claw trimming, irregular quarantine, and no attention to health aspects during acquisition of the animals were considered as major risk factors for the occurrence of those diseases. The McNemar test for dependent samples showed significant statistical differences between the occurrence of foot disease, clinical mastitis and metritis, in spite of the poor association between those diseases. It was concluded that there was no expressive relationship between foot diseases, clinical mastitis and metritis in lactent cows.

Efecto del etilenodinitrilo tetracetato de calcio y cobre y del lactobionato de cobre parenteral en el tratamiento de la papilomatosis cutánea bovina

The purpose of this study was to compare the effect of parenteral copper compounds on different clinical presentations of bovine cutaneous papillomatosis in 50 crossbred (Zebu x European) dairy type female cattle of different ages. Animals were distributed among five 10-animal groups (GI, GII, GIII, GIV, and GV). GI and GIII were affected by the pediculated clinical presentation, GII and GIV had the flat presentation, and GV included five animals with the pediculated form and five animals with flat lesions. Animals in GI and GII were treated subcutaneously with 200 mg calcium/copper ethylenedinitrile tetraacetate, and animals in GIII and GIV received 287.4 mg of an organic copper combination (mostly copper lactobionate). Control group GV was treated with 10 ml saline. Calcium/copper ethylenedinitrile tetraacetate was more efficacious (P<0.05) than copper lactobionate since 9 cows (45 %) vs only 5 % were cured respectively. Cure rate was higher (P<0.05) among animals with the pediculated form (36 %) than those with the flat form (8 %). Cattle younger than 12 mo of age showed the best (P<0.05) response to treatment with a 45 % cure rate, as compared with 6.7 % among the 13-36 mo and 6.7 % among the 37-72 mo old brackets.
