<b>Performance of piglets submitted to different replacement levels of soybean meal protein by dehydrated egg protein</b> - DOI: 10.4025/actascianimsci.v30i4.3746

Abstract

This study aimed to determine the average daily weight gain, daily feed intake and the feed conversion ratio of pigs in initial phase (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 four treatments 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 the initial phase, up to 9%. However, when evaluating the cost-benefit ratio, the control treatment was the most profitable one.
