Protein requirements of lactating Chios ewes.
The digestible protein requirements of lactating ewes were studied with Chios 3 ewes during the declining state of lactation in two nitrogen balance and three feeding trials. A 60 kg ewe producing 1.0 or 2.0 kg milk of 6% protein and maintaining weight equilibrium, required 134 and 230 g digestible protein daily, respectively. These requirements were obtained with ewes receiving 110 Kcal metabo...

15 صفحه اولUse of crude glycerol, a biodiesel coproduct, in diets for lactating sows.
An experiment was conducted to evaluate the effect of dietary crude glycerol in lactating sow diets on sow and litter performance under heat stress conditions. Mixed parity (range = 0 to 13) sows (n = 345; 253 +/- 24 kg of BW) were assigned randomly within gestation housing location and parity to 1 of 4 dietary treatments. Treatments consisted of a corn-soybean-based control diet (CON) and 3, 6...
متن کاملGastrointestinal transport of calcium and glucose in lactating ewes
During lactation, mineral and nutrient requirements increase dramatically, particularly those for Ca and glucose. In contrast to monogastric species, in ruminants, it is rather unclear to which extend this physiological change due to increased demand for milk production is accompanied by functional adaptations of the gastrointestinal tract (GIT). Therefore, we investigated potential modulations...
متن کاملEvaluation of rifamycin SV and rifampin kinetics in lactating ewes.
Serum and milk concentrations of rifamycin SV and rifampin were determined in lactating ewes after a single intravenous injection, and pharmacokinetic parameters were evaluated by the two-compartment open-system model. Rifampin was distributed throughout a greater volume than rifamycin SV and was eliminated more slowly from the body. The concentrations of the two drugs, both lipophilic weak aci...
