Productivity of Lagoon Cattle Farms on the Islands of the Municipality of Sô-Ava in the South of Benin
Journal Title: Saudi Journal of Engineering and Technology - Year 2017, Vol 2, Issue 11
Abstract
Abstract:This study, which examines the productivity of Lagoon cattle farms located on the islands at risk of flooding in the municipality of Sô-Ava in the Oueme river valley in southern Benin, took place between November and December 2016. It concerns 95 farms of bovine Lagoon distributed on the various islands of the Municipality. These operations have a total of 2496 head of Lagoon cattle herds. It aims to compare the demographic parameters obtained on the different islands during the last year and that of 2010 where the island experienced a flood. Data were collected from a 12-month retrospective survey (12MO). The annual demographic parameters (annual rate, calving, abortion, stillbirth, mortality, annual net growth, annual exploitation rate and annual rate of multiplication) were calculated and analyzed under software R3.3.2. Thanks to the t12mo package. Except for the mortality rate, there were no significant changes in reproductive rates (p> 0.05) regardless of the herd of residence of the herds. The annual mortality rate was significantly higher (p <0.05) on the Dekanmey, Houedo and Sô-Ava islands compared to that of the AhomeyLokpo island (0.124, 0.142, 0.113, vs 0.071an-1). The year had a significant effect on the demographic parameters (p <0.05) as well as on the overall demographic indicators obtained. Implementation of a resilient model to climate shocks would be an incentive for the sustainable management of these farms. Keywords:Productivity, Demographic parameters, Bovine Lagoon, Sô-Ava, Oueme
