In this study, the performance of male pigs immunized against GnRH was determined in relation to the onset of their biological response to the immunization. Pigs were immunized at 9 and 17 wk of age and were housed in a pen together with both a surgi

We have investigated, under the normal conditions of local Chinese pig farming, castration of young male pigs by vaccination with a newly developed vaccine against gonadotrophin releasing hormone (GnRH). Because of the very early onset of puberty, lo

Post-weaning anoestrus was studied in eighteen primiparous sows, selected from a breed showing a high proportion of anoestrous sows. The sows were studied from late lactation, through weaning at day 29 post-partum (p.p.), until day 21 post-weaning (p

Several methods have been described for obtaining precise physiological progesterone data from lactating cows. In certain situations it is advantageous to use skim milk for progesterone estimation for which we have developed a sensitive EIA. Progeste

Basal and TRH-induced PRL secretions were investigated for adult Landrace boars housed in two social environments. Socially nonrestricted boars (N = 4) were individually penned adjacent to ovariectomized gilts that were hormonally induced into estrus

We have developed and validated a sensitive, simple and direct (i.e. without extraction) enzyme immunoassay (EIA) system for the measurement of progesterone in bovine milk and blood plasma. Progesterone (P) has been analysed by a microtiterplate EIA,
