The effects of two oestrus detection procedures and intense boar stimulation near the time of oestrus on mating efficiency of the female pig

摘要: Abstract In the first experiment, a higher oestrus detection rate (percentage of cycling gilts that were detected in oestrus) and mating mated) achieved when checked for corridor adjacent to boar pens than they their own pens, which separated from by 1.0 m-wide (90 v. 52% 87 52%, respectively). second several housing treatments imposed over 21-day period. A lower proportion I stage (positive response back-pressure test both presence absence boar) was wire-mesh pen division m (48 81% 47 81%, It concluded females should be housed near, but not to, boars at time using test, very close boars.
