Abstract |Preventing animal genetic resources from genetic erosion implies taking into account their demographic aspects within farming systems with the view to facilitate the interpretation and understanding of livestock systems based on events likely to occur. The aim of this study is to evaluate demographic traits in four Borgou cattle farming systems previously identified in northern Benin using the 12MO retrospective cross-sectional survey method. The results showed that females were dominant (>65%) in “semi-intensive purebred Borgou cattle farming” (SIntPur), “large transhumant of Zebu and Borgou crossbred cattle farming” (LargeZB) and “small transhumant of Zebu and Borgou crossbred cattle farming” (SmallZB) conversely to “sedentary purebred Borgou cattle farming” (SedPur) with less than 20%. SIntPur and SedPur herds presented the best reproduction parameters: higher prolificacy rates (0.967±0.017 and 0.913±0.060 year-1 respectively) and parturition rates (0.710±0.049 and 0.685±0.062 year-1 respectively). Intake rates were higher in SedPur herds (p<0.05). Offtake rates were higher in LargeZB and SmallZB herds (0.055±0.009 and 0.096±0.028 year-1 respectively). Regarding Global Demographic Indicators, SedPur herds showed higher multiplication rate (1.392 year-1±0.201). Production rates were higher and positive in SedPur (0.444 year-1±0.081) farms followed by SIntPur (0.202 year-1±0.022) farms while lower and negative in LargeZB and SmallZB farms (-0.036 year-1±0.005 and -0.040 year-1±0.002 respectively). Growth rates were higher and positive in SIntPur (0.271 year-1±0.028) farms followed by SedPur (0.022 year-1±0.201) farms while lower and negative in LargeZB and SmallZB farms (-0.064 year-1±0.013 and -0.032 year-1±0.028 respectively).
