CORASSA, A.; KIEFER, C.  and  GONCALVES, L.M.P.. Lysine nutritional plans for swine from initial to finishing phase. Arch. zootec. [online]. 2013, vol.62, n.240, pp.533-542. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922013000400006.

This study was conducted to evaluate the lysine nutritional plans for pigs reared in mixed batches, 63 to 164 days of age. Two hundred and forty animals, with initial body weight of 24.6±1.5 kg, were distributed in a randomized block design with four nutritional plans (A: 1.05-0.88-0.82-0.78-0.78; B: 1.05-0.87-0.80-0.76-0.76; C: 1.05-0.85-0.770.71-0.71 and D: 1.05-0.82-0.75-0.70-0.69 % of digestible lysine, respectively from 63 to 74 days, 75 to 89 days, 90 to 111 days, 112 to 135 days and 136 to 164 days) with six replicates of ten animals each. The nutritional plans with the sequences A and B improved feed conversion of pigs when compared to other nutritional plans. Pigs fed on the nutritional plan D had lower hot carcass weight. The nutritional plan corresponding to sequence C, respectively, for pigs from 63 to 74 days, 63 to 89 days, 63 to 111 days, 63 to 135 days and 63 to 164 days meet the nutritional needs and maximizes the performance and carcass traits of the initial at finishing phase.
