Genetic analysis for mastitis resistance and milk somatic cell score in French Lacaune dairy sheep.

Genetic analysis for mastitis resistance was studied from two data sets. Firstly, risk factors for different mastitis traits, i.e. culling due to clinical or chronic mastitis and subclinical mastitis predicted from somatic cell count (SCC), were explored using data from 957 first lactation Lacaune ewes of an experimental INRA flock composed of two divergent lines for milk yield. Secondly, genetic parameters for SCC were estimated from 5 272 first lactation Lacaune ewes recorded among 38 flocks, using an animal model. In the experimental flock, the frequency of culling due to clinical mastitis (5% ) was lower than that of subclinical mastitis (10% ) predicted from SCC. Predicted subclinical mastitis was unfavourably associated with the milk yield level. Such an antagonism was not detected for clinical mastitis, which could result, to some extent, from its low frequency or from the limited amount of data. In practice, however, selection for mastitis resistance could be limited in a first approach to selection against subclinical mastitis using SCC. The heritability estimate of SCC was 0.15 for the lactation mean trait and varied from 0.04 to 0.12 from the first to the fifth test-day. The genetic correlation between lactation SCC and milk yield was slightly positive (0.15) but showed a strong evolution during lactation, i.e. from favourable (-0.48) to antagonistic (0.27). On a lactation basis, our results suggest that selection for mastitis resistance based on SCC is feasible. Patterns for genetic parameters within first lactation, however, require further confirmation and investigation.

Stabilizing suspension procedure involving multiple tendon transfers in a patient with multiple sclerosis.

Patients afflicted with multiple sclerosis develop weaknesses of the lower extremity resulting in drop foot, making ambulation very difficult. A review of the literature by the authors failed to reveal any cases or manuscripts discussing the podiatric management of patients with this disease. This manuscript offers a review of the disease, common principles regarding tendon transfers, a case report, and unique surgical approach consisting of a stabilizing suspension procedure involving multiple tendon transfers. At 1 year following correction, the patient was pleased with the results and ambulatory status.
