A survey was conducted on 115 farms located in towns and villages of the Senegalese groundnut basin in order to establish demographic and zootechnical parameters of local pig production units. The results show that pig producers use very rudimentary farming techniques and equipment, alimentation practices are inefficient, sanitary regulations are not applied and prophylaxis is non-existent. There are on average two pigs per farm. The pyramid graph indicates a high rate of young animals. The number of piglets born alive per farrow ranges between six and eight with a mortality rate before wearing of 12.5 percent. The average daily pains are low: 156g for mares and 117g for females. The economic analysis shows a low profit margin because of the high price of both the animals and the feed.
