Efeitos de diferentes ambientes de criação sobre o desempenho de leitões na fase de creche

Abstract

Currently, Brazil is among the countries that export more pork in the world, increasing its production by about 4% a year, it is seeking a production increasingly quickly and efficiently without harming the animal welfare. Thus the aim of this study was to evaluate the effects of different authoring environments on economic and productive performance of piglets in the nursery. The experiment was conducted at Granja Celito Peretto, in the municipality of Dois Vizinhos - PR. 240 crossed piglets were used, with average weight of 6 kg, 21 days old, distributed in a completely randomized design with two treatments: T1 Crechário with castings and suspended cages and T2 Crechário with partially leaked bays and suspended and with concrete floor parts, with 4 repetitions and 30 animals each. The performance parameters evaluated were weight gain, feed intake and feed conversion. While the cost of feed per kg of produced pig was calculated as follows: price per kilogram of feed multiplied by feed conversion. Performance data were submitted to analysis of variance, the difference between the average verified by test F. There was no effect (P> 0.05) of treatments on performance parameters. However, treatment 1 had the lowest cost of feed per kg of produced pig. Depending on the economic results, it is recommended to use cages suspended in the nursery phase.
