Caractérisation phénotypique du comportement alimentaire chez la chèvre laitière

Abstract : Agricultural systems are changing rapidly and are subject to increasing societal and economic pressures. A key element in their adaptation is to find an optimal combination between the ability of animals to adapt to changing environments, the maintenance of production performance and husbandry methods that would best support individual variability. The development of precision livestock farming, with the increasing ability to automatically record behavioural and production parameters, makes it possible to obtain accurate information on-farm in real time. It is therefore crucial that the biological relevance of the variables measured be known.However, due to the lack of studies on this subject, we know little about feeding behaviour of individual ruminants, and in particular goats, and what factors contribute to the individual variation.Using goats, work presented in thesis showed that 1) goats have preferences in terms of feeding posture and types of feed offered, 2) important inter-individual variability of feeding behaviour exists among goats housed in groups, while the individual feeding behaviour pattern is relatively stable over time, 3) when goats are subjected to feeding challenges such as changes in the frequency of feed delivery, they adapt their feeding behaviour to these changes, but keep a stable pattern of feeding behaviour.
