Vasectomised boars are an extremely useful addition to a pig farm. However, there is a tendency for producers to keep these animals for excessive periods, says Paul Thompson, veterinary consultant to pig-breeding company, ACMC.
Such boars can become extremely heavy and then pose a risk of injuring gilts. While it takes time for boars to mature and become good pheromone producers a watch should therefore be kept on their age and condition and a regular replacement plan be put in place.
