Improved growth performance, food efficiency, and lysine availability in growing rats fed with lysine-biofortified rice

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 availability of in-acetyl-d-lysine and in-methyl-dl-lysine for growth.

Growth and antioxidant status of broilers fed supplemental lysine and pyridoxine under high ambient temperature

Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detect...

Lysine Availability in AminoMax Pro

Vegetable protein meals are heated during processing to remove antinutritional factors. For example, soybean meal contains protease inhibitors that reduce protein digestibility, lectins that cause lesions in the gut wall and goitrogens that influence the function of thyroxin. Canola meal can contain glucosinolates, which along with the enzyme myrosinase can produce compounds that irritate the g...

Application of the reactive lysine procedure to estimate lysine digestibility in distillers dried grains with solubles fed to growing pigs.

Two experiments were conducted to measure the reactive Lys concentration in corn distillers dried grains with solubles (DDGS). In expt 1, reactive Lys was measured in 33 sources of DDGS using two procedures: the homoarginine procedure and the furosine procedure. The concentration of reactive Lys in DDGS was then correlated with the concentration of standardized ileal digestible (SID) Lys in DDG...
