Pratiques de suivi de l'état corporel en élevage bovin laitier : enquête auprès d'éleveurs et de conseillers

Abstract : In dairy production, the preservation of reproductive performances is crucial to ensure the sustainability, but several reproduction troubles exist such as abnormal cyclicity or infertility. These are potential culling criteria. The project called CowPILOT aims at finding solutions to monitor body condition individually to optimise reproduction success. In this project, the purpose of this study is to establish how breeders and breeding advisors use the cow body condition and to highlight profiles interested by an individual monitoring. Thus, 29 semi-structured interviews were led and analysed (14 breeding advisors and 15 breeders). Only three people are scoring the cows. According to the interviewees, the scoring of body condition is time-consuming and non-recoverable. Body condition is mostly used as an indicator of the breeding management at strategic moments: the evaluation of the cows’ food and 2/3 of the interviewees use it as a reproduction criterion. Individual monitoring is for breeders because breeding advisors come at the farm every two weeks at the best. Thanks to this overview, four profiles for the breeding advisors and four for the breeders were found. Only one breeder profile was different from the others. These breeders have already individual practices, such as the use of automatic concentrate feeder, and have reasonable workload and sometimes digital tools and reproduction monitoring. They could be interested in individual monitoring of body condition to optimise reproduction.
