ABSTRACT

The objective of this work was to monitor a cohort of local chickens after caponizing in order to improve their zootechnical performance in the Urban Commune of Kankan. At the end of our work, the following results were obtained: The survey, through consultation with the managers, revealed that there is a good relationship between the managers and the traditional poultry farmers. The different species of poultry raised include chickens, ducks, guinea fowl, turkeys, etc. The search of the archives did not provide us with any results on cockerel caponization. However, the managers are well aware of the importance of the practice of caponization, which is unfortunately not practiced by the breeders in the commune. The experiment was carried out on two batches of 10 cockerels of the local breed. The caponization was carried out at 8 weeks of age with a mortality rate of 20%. Data were collected on the live animals by weekly weighing for 13 weeks and on the carcasses after slaughter. The results show that live weight and carcass weight in the two batches are different. The live weights recorded were 992.14 g and 714.7 g, respectively, in capons and whole males with yield weights of 66.49% and 55.46%. The average weekly gain (AWG) was higher in capons than in whole males.
