Objetivou-se determinar o ganho de peso, o consumo de ra o e a convers o alimentar de su赤nos em fase inicial (15 a 30 kg de peso) alimentados com quatro diferentes n赤veis de substitui o (0, 3, 6 e 9%) da prote赤na do farelo de soja pela prote赤na do ovo desidratado. Foram utilizados 32 su赤nos (16 machos castrados e 16 f那meas) em um delineamento em blocos casualizados, com quatro tratamentos e quatro repeti es cada, em que a unidade experimental foi composta por um macho e uma f那mea. Os tratamentos foram 0, 3, 6 e 9% de prote赤na do ovo desidratado em substitui o 角 prote赤na do farelo de soja. Os dados obtidos foram submetidos 角 regress o linear para os n赤veis de 3, 6 e 9% de ovo desidratado, e o tratamento-testemunha (0%) foi comparado com os demais aplicando o teste Dunnet a 5% de probabilidade. Os n赤veis de substitui o da prote赤na do farelo de sojapela prote赤na do ovo desidratado n o influenciaram as vari芍veis de desempenho dos animais na fase inicial, at谷 9%. Entretanto, avaliando a rela o custo-benef赤cio, o tratamentocontrole foi o mais rent芍vel. This study aimed to determine the average daily weight gain, daily feed intake and the feed conversion ratio of pigs in initialphase (15 to 30 kg of weight) fed with four different levels of substitution (0, 3, 6 and 9%) of soybean meal protein by dehydrated egg protein. Thirty-two pigs (16 castrated males and 16 females) were used in a completely randomized blocks statistical design, with fourtreatments and four repetitions each; the experimental unit was composed by a male and a female. The treatments were 0, 3, 6 and 9% of dehydrated egg protein in replacement of soybean meal protein. The data obtained were subjected to linear regression for the levels 3,6 and 9% of dehydrated egg; the witness (0%) was compared with the other treatments applying Dunnett＊s test at 5% probability. The replacement levels of soybean meal protein by dehydrated egg protein did not influence the performance variables of the animals in theinitial phase, up to 9%. However, when evaluating the cost-benefit ratio, the control treatment was the most profitable one.
