Efficiency of lysine utilization by growing meat quail

Efficiency of lysine utilization by growing steers.

This study evaluated the efficiency of Lys utilization by growing steers. Five ruminally cannulated Holstein steers (165 ± 8 kg) housed in metabolism crates were used in a 6 × 6 Latin square design; data from a sixth steer was excluded due to erratic feed intake. All steers were limit fed (2.46 kg DM/d), twice daily, diets low in RUP (81% soybean hulls, 8% wheat straw, 6% cane molasses, and 5% ...

The effect of frequency of feeding on the utilization of free lysine by growing pigs.

The effects of excessive amounts of protein on lysine utilization in growing pigs.

Two experiments were conducted to investigate whether the utilization of lysine in growing pigs is affected by the level of excess protein in the diet. Nine lysine-deficient diets containing 100, 200 or 300 g crude protein/kg and between 1.2 and 6.8 g ileal digestible lysine/kg were prepared. In the first experiment the apparent ileal digestibility of lysine in three of the nine diets was deter...

Utilization of Urea and Urease Treated Rice Straw by Indigenous Growing Cattle

The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...
