Role of boar-related odours in puberty attainment in the gilt



Role of boar-related odours in puberty attainment in the gilt



British Society of Animal Production Winter Meeting 29-31 March 1982, Crown Hotel, Harrogate (Paper 46): 2



In the 1st of 3 experiments, 40 Large White (LW) X (Landrace X LW) prepubertal gilts were exposed, at 165 days of age, to (1) 5 alpha -androstenone, (2) 3 alpha -androstenol, (3) 5 alpha -androstenone + 3 alpha -androstenol, (4) a diethyl ether extract of boar submaxillary salivary gland, or (5) received no pheromone stimulation (controls). The percentage of gilts reaching puberty before 220 days of age was 25, 50, 37.5, 12.5 and 25 for the 5 groups resp.
