Padilla-Rivas Wolfgang Holtz Multidisciplinaria (Ciencias Naturales y Exactas) LH NON INHIBIN BREEDING SEASON INTENSIVE SAMPLING The objective of this study was to determine the LH secretion during the breeding and the anestrous season in Boer goatsactively immunized against inhibin. In this experiment, 12 immunized and 12 non-immunized (control) Boer goat does wereused. Permanently indwelling jugular catheters were placed permitting repeated blood collection for 6 h periods. During thebreeding season, samples were taken during the luteal phase (days 10 to 16 of the cycle) on every other estrous cycle. Duringthe non-breeding season, samplings were conducted every 6 weeks. Plasma LH concentrations were determined by means ofELISA. During the non-breeding season, immunized animals showed signifi cantly lower LH concentrations than control animals(P < 0.01). During the breeding season, LH secretion was hardly affected by inhibin- immunization with only the pulse amplitudebeing slightly, though signifi cantly reduced (P < 0.01). In both immunized and non-immunized animals, the pulse rate was signifi -cantly enhanced during the non-breeding season as compared to the breeding season (P < 0.01). In conclusion, during the breedingseason goats showed lower plasma LH concentrations than during the non-breeding season. During the breeding season LHsecretion is only slightly affected by active immunization, whereas during the non-breeding season the LH-suppressive effect ofinhibin immunization was more pronounced. 2006 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42337105 en http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.1 Vol.37 |
