Influence of moderate nutritional stress during gestation on reproduction of Collared peccaries (Tayassu tajacu)

摘要: This study examined the influences of moderate restrictions in maternal energy and protein intake during gestation on reproductive success foetal development Collared peccary (Tayassu tajacu). Sixteen captive females from southern Texas were bred January 1983 randomly assigned to one four experimental rations for duration gestation. Experimental diets formulated a factorial design with two levels (HE = high, ME moderate) (HP MP moderate). Only HEHP diet gained weight Moderate or had no influence number young born alive, litter size, length Foetal was only minimally affected by prolonged intake. suggests that nutrition-related prenatal mortality between implantation parturition may not be most important mechanism limiting herd recruitment periods drought Texas.
