Abstract
Abstract. The study provides baseline data regarding 17-β-estradiol (E2), progesterone (P4), and cortisol profile of 30 Nicastrese goats during different physiological periods. Animals were
evaluated monthly from the pre-mating period (non-pregnant), during pregnancy, and
from 30 to 105 d of lactation. The effects of single or twin births and
the kid's sex were also considered. Serum E2, P4, and cortisol
concentrations were measured using immunoenzymatic assay kits. The highest
concentrations of E2 and P4 (P<0.0001) were found during
pregnancy and their lowest values (P<0.0001) in the non-pregnant
period. E2 was negatively correlated with P4 (r=-0.41; P<0.01) during lactation. The mothers with twin kids showed the
highest concentration of P4 (P<0.04) at > 95–115 d of gestation and the lowest of E2 (P<0.04) at
> 50–70 d of lactation. Pregnant goats carrying male kid(s)
presented the highest E2 concentrations (P<0.02) at
> 130–150 d of gestation. Different physiological conditions
induced a temporal relationship with the endocrine profile in Nicastrese
goats. Understanding the effects of single or twin fetuses on the gestation
and lactation will also be helpful to improve the managemental approach for
the health of mothers and their kids.
