The objective of the current study was to evaluate the effect of supplementation of either L-methionine (L-Met) or DL-methionine (DL-Met) to diets of starter pigs on nitrogen (N) balance, metabolism, ...
Four 4-month old CharolaisDorset male sheep (initial liveweight 25.01.1 kg), fitted with rumen and abomasal fistulas and nourished by total intragastric infusions, were used to study t...
We compared the effects of supplementing L-lysine??SO4 to L-lysine??HCl on growth performance, nutrient digestibility and nitrogen retention in weaning pigs. A total of 96 crossbred pigs, weaned at 21...
The responses of whole body protein and glucose kinetics and of nitrogen (N) metabolism to non-protein energy intake (NPEI) were determined using an isotope dilution approach and measurement of N bala...
The influence of varying levels of urea and additives on nitrogen (N) retention and chemical composition of wheat straw was studied. The wheat straw was treated with 4, 6 and 8% urea and ensiled with ...
