Incidences sanitaire et facteurs de risque des mammites sur la fertilité des vaches laitières. Étude de cas.

Abstract

Mastitis is an inflammation of the udder , mastitis is particularly preoccupying and frequent in dairy farming.Milking-induced mastitis can weakened and contaminated by bactéria ,which causes this inflammation which affects reproduction and the fertility of the cow. The factors responsible for bovine infertility are of individual natures,but also,and above all collectively,the causative etiophatogenic mechanisms are numerous and little know.The economic losses are enormous when both are present at the same time in the egg. We have initiated a study which aims to identify the different bacteria that cause breast inflammation and to know their risk to fertility in three targeted dairy cattle breeding operations located in the wilaya of Oran.We have confirmed the presence of these pathogenic bacteria in the farms.These results are linked in the field by the prevention measures and the method of cleaning and hygiene of each farm.
