متن کاملNutritional plane and selenium supply during gestation affect yield and nutrient composition of colostrum and milk in primiparous ewes.
The objectives were to investigate effects of nutritional plane and Se supply during gestation on yield and nutrient composition of colostrum and milk in first parity ewes. Rambouillet ewe lambs (n = 84, age = 240 ± 17 d, BW = 52.1 ± 6.2 kg) were allocated to 6 treatments in a 2 × 3 factorial array. Factors included Se [adequate Se (ASe, 11.5 µg/kg of BW) or high Se (HSe, 77.0 µg/kg of BW)] ini...
متن کاملEffects of gestational plane of nutrition and selenium supplementation on mammary development and colostrum quality in pregnant ewe lambs.
