(3) Incubation of normal pig lymphocytes in serum samples collected from 10 sows immediately before, and at daily intervals after mating with a vasectomized boar significantly elevated the rosette inhibition titre (RIT) of a standard antilymphocyte serum in 6 animals on the first but not on the 2nd and 3rd day after copulation.
(4) The nuclei were isolated from boar spermatid or sperm cells at three distinct stages of spermatogenesis: just before the completion of a maturation process in the testis (late spermatid), immediately after a subsequent transformation into spermatozoa (caput spermatozoon), and after full maturation (cauda spermatozoon).
(5) In addition, prior saturation of the substrate layers with acrosin inhibitor (SSPI-I, II) from boar seminal plasma prevented the lysis reaction.
(6) E. coli from wild boars in a zoological garden has less sensitivity than from domesticated animals.
(7) This study investigated the applicability of the method to boar sperm motility measurement.
(8) In the same boar, the lengths of the fully synapsed arms of the quadrivalent varies from one quadrivalent to the other and heterosynapsis was obvious.
