Efeitos da adição de pó de rocha na nutrição de frangos de corte de 1 a 42 dias de vida

Abstract

In this course completion work, we evaluated the best concentration of rock dust to include in the diet of broiler chickens from 1 to 42 days of age. The objective was to evaluate the performance of these birds when they were slaughtered at 42 days of age. 132 Hubbard chicks were used, divided into four treatments, namely: control treatment; 0.5%; 1.0% and 2.0% inclusion of rock dust. The experiment was carried out within the Federal Technological University of Paraná de Dois Vizinhos at UNEPE Pequenos Animalis, where the animals were separated by pens, with 11 birds in each, totaling three pens per treatment. The birds were weighed at the beginning of the experiment (day one) and at the end (day 42), in addition to weighing the feed to obtain the feed conversion of these animals. At the end of the experiment, on day 42, the birds were slaughtered, and only then the carcass quality was assessed by weighing the cuts. As a result, better carcass weights were obtained by adding 0.5% rock dust to the bird feed.
