Resumo
Were used 64 weaned pigs, distributed in eight treatments: ration with skim milk (SM), three rations with crescent levels of swine plasma (SP), three rations with whole egg (WE) and a ration with high inclusion of soybean meal (SB). Daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) were evaluated. The animals that consumed ration SB have the mean of DWG higher that other treatments, and inferior FC, from 35 to 48 days of age. The crescent levels of SP promoted linear reduction in DWG, from 21 to 35, and from 35 to 48 days of age, in DFI from 48 to 138 days of age and linear increased in FC from 21 to 35 of age. Considering the weaned phase until finishing, initial rations can be formulated with SP and WE substituted partially the CP of skim milk in 25 and 45%, respectively.
