The objectives of this work were to estimate the requirement of lysine from 7 to 12 weeks and to evaluate their effect on the egg production phase. Two hundred egg-white pullets (EW), and two hundred egg-brown pullets (EB) strains were allotted in randomized block design, and fed a basal diet with 16.0% of crude protein (CP) and 2,900 kcal/kg metabolizable energy (ME), supplemented with L-lysine HCl for the level of 0.50, 0.55, 0.60, 0.65, and 0.70% of total lysine in […]

The objective of this work were to estimate the requirement of lysine from 0 to 6 weeks and to evaluate the posterior effect on the performance of two egg-type strains. Three hundred egg-white pullets from 0 to 6 week of age and three hundred egg-brown pullets from 0 to 6 week of age were allotted to a randomized block design with five treatments and four replicates. A basal diet with 18.50% of crude protein (CP) and 2900 kcal metabolizable energy […]
