Extract

Low feed intake after weanimg is common, in which case it is recommended that concentrations of nutrients, such as lysine and energy by increased. Lysine is the first limithing aminoacid in most diets used for maximizing protein accretion during pig growth. A fundamental factor that determines protein depositionis the content of metabolizable energy (ME) which is need for protein anabolism. It is convenient that the dietetic energy and lysine (LYS) contents supply the requirements for maintenance and body mass accretion, according to specificities involved in modern pig production. The purpose of the present study was to investigate the effect of ME and digestible LYS levels on the performance and nitrogen (N) retention of piglets during the initial-1 phase and subsequent effects during the initial-2 phase.
