Inclusão da quirera de arroz em rações de suínos na fase de creche

Abstract

It was used 30 piglets, castrated male and female, of commercial lineage, weaned at 21 days of age and with average live weight of 6.65 kg, with the objective to evaluating the effect of the inclusion of different levels of broken rice on the frequency of diarrhea, productive performance, how so the economic viability of piglets in the nursery phase I (21 to 42 days of age), nursery phase II (43 to 63 days of age), and total period (21 to 63 days of age), how so the economic viability. The experimental design used was a randomized blocks randomized, with 5 treatments (inclusion levels of broken rice: 0,0; 14,0; 28,0; 42,0 and 56,0%) and 6 replicates per treatment, being the experimental unit (part) consists of an animal. The criterion used for block formation was the initial weight of piglets. According to regression analysis, were not observed significant effects between the levels of inclusion of broken rice in diets in any of the variables of zootechnical performance, as well as, there were not significant difference between control treatment and treatments with the inclusion levels of broken rice when compared by Dunnett test (5%). The results of observations of the frequency of diarrhea indicated that the inclusion of broken rice provided no changes in the incidence of diarrhea in animals. According to the economic study the inclusion of broken rice proved viable until the level of 56.0%. Therefore, it can be concluded that the use of broken rice in diets of pigs in the nursery phase was technically and economically viable until the level of 56,0% for inclusion
