Desempenho de frangos de corte suplementados com diferentes níveis de composto comercial a base de óleos funcionais e alga

Abstract

The aim of this study was evaluate the effect of dietary inclusion of increasing levels of functional oils and algae (OFA) on performance of broilers. The research was be performed in the Paraná Federal Technological University experimental avian, campus Dois Vizinhos during 42 days. 560 birds were used, and distributed in forty boxes with fourteen birds. The design adopted was a randomized block design with five treatments and eight repetitions. Treatments consist of increasing levels of OFA, as following: 0; 0.5; 1; 1.5; and 2 kg / ton OFA added on top of the basal diet based on corn and soybeans. Feeding conversion, weight gain, diet consumption, mortality and economic viability were evaluated. The supplementation of compound basic functional castor oil and cashew algae showed viable in poutry commercial production, and under experimental condition, the dose which improved the performance variables of the birds was 1.3 kg compound per tonne of ration.
