商品簡介

After 20 years of practice in Senegal, AI should no longer be a national campaign affair, but rather an everyday activity, depending on demand. The democratisation of AI will only be effective when each breeder can benefit from this biotechnology in due course and by his own means. The study reveals that within the framework of the project, the cost of AI on induced heat is 35,867FCFA against 22,715FCFA for AI on natural heat. However, outside the project, the cost of AI on natural heat is 20,305FCFA, which represents a saving of 15,562FCFA and 43.4% of the cost of AI on induced heat. Economically, AI on natural heat is better, provided that the intervention zone of each inseminator is circumscribed within a 15 km radius. It is also essential that the farmer agrees to invest more time in heat detection.
