Abstract: Heat stress, increased morbidity and mortality most often characterize the direct impact of climate change on livestock farming and modify the conditions of animal production. The present study aims to analyze the influence of climate change (CC) and breeding modes on the reproductive parameters of cattle herds in the cotton zone of North Benin over the last 32 years as well as the local perception of CC by farmers. It was based on a sample of 694 breeders in all ten districts of the commune of Banikoara in North Benin. The generalized linear model based on the Beta distribution was used to test the effect of climate change and breeding modes on the reproductive parameters of the cattle herds (apparent fertility rate, numerical productivity at, fertility rate, farrowing rate and abortion rate). Principal Component Analysis (PCA) was used to describe the criteria that determine the local perception of climate change by livestock farmers. The study revealed a significant decrease in fertility, calving and abortion rates among cattle herds in the commune of Banikoara, regardless of the farming mode (Bariba, Peulh) on the one hand and on the other, according to climate variations observed from 1988 to 2020. The apparent fertility rates according to the breeding modes and the time gap are not significant at the 5% threshold, but only the numerical productivity at weaning varied very significantly between 1988 and 2020 (p<0.001). The local perception of farmers in the agro-pastoral zone of cotton production is characterized by frequent droughts, strong winds, excessive heat, late and frequent rainfall, which leads to a drop in weaning productivity, reduced births, lower fertility and fertility but increased abortions. All in all, the degradation of herd reproduction parameters due to climate change in relation to livestock farming systems calls on both the scientific and political communities to find sustainable solutions for livestock farmers in order to strengthen nutritional security. This can be done by implementing strategies that limit calving losses and conditions that do not penalize the reproductive capacity of cattle.
