The dehydrogenase pathway and the succinylase are involved in synthesis of L-lysine Corynebacterium glutamicum. Despite low contribution rate to production, is favorable for its simple steps potential increase production L-lysine. effect ammonium (NH4+) concentration on biosynthesis was investigated, results indicated that can be promoted a high NH4+ environment. In order reduce requirement NH4...

An 11-week feeding trial was conducted to assess the dietary lysine requirement for juvenile Hemibagrus wyckioides. Six isoproteic and isoenergetic diets (41.66% crude protein, 20.56 kJ/g gross energy) containing 1.1%, 1.5%, 1.9%, 2.3%, 2.7%, 3.1% were prepared feed juveniles (average initial body weights of 1.25 g), respectively. The weight gain, specific growth rate (SGR), conversion ratio (F...

Self-selection of dietary lysine was studied in one 42-d experiment involving 100 Large White growing pigs, with an equal number of females and castrated males, initially weighing 17.7 kg, within 5 treatments of 20 animals in each. A common basal diet (17% CP, 13.8 MJ DE/kg) based on maize, soybean meal and peanut meal, and containing a deficient level of lysine (0.61%), was used. Supplementary...
