Two experimentswere carried out to determine the chemical composition, nutrients digestibilityand digestible energy and protein of spray-dried egg (OP) and to study the performanceand plasma and blood components of weanling pigs fed diets containing OP. Inthe Experiment I, eight pigs were used for digestibility assay. The animalswere assigned to two treatments and four replications/treatment. The treatmentsconsisted of a basal diet and test diet (70% of basal diet + 30% of OP). Themethod was the partial faeces collection (0.5% Cr2O3).The apparent digestibility coefficients of dry matter, gross energy, crude proteinand crude fat were, respectively, 80.81, 87.14, 82.00, and 70.55%. From theresults of apparent digestibility coeficients and the values of crude protein(56.53%) and gross energy (5,897 kcal/kg), values of 43.90% of digestible proteinand 5,140 kcal/kg of digestible energy for OP were calculated. In the ExperimentII, ninety pigs were weaned at 24 days of age with 5.6 kg live weight. The treatmentsconsisted of five dietary levels of 0, 25, 50, 75 and 100%, as a replacementof plasma (PS) protein for OP protein. Pigs were alloted to a randomized blockdesign with nine replications per treatment. No treatment effects were observedon performance for 1-14 day post-weaning phase. For the 15-28 d phase and forthe total period, linear reductions of GDP and CDR were observed, as the dietaryOP levels increased. No treatment effects were observed on plasma and bloodcomponents by the inclusion of spray-dried egg. It was not recommended to replacethe PS by OP in nursery diets.
