Métodos alternativos de muda forçada para codornas japonesas

Abstract

The experiment was conducted to evaluate the effect of different methods of forced molting during and after the application of treatments on performance and egg quality of laying quails. They were used 480 Japanese quails, with 52 weeks of age, which were submitted to the following treatments: Fasting = total fasting feed (control treatment); MFS = incorporated feed supply corn and soybean meal; ZN = feed supply with high Zn (7,300 ppm); FT = bran supply; Corn = ground corn supply. The experimental design was completely randomized with 5tratamentos and 4 repetitions. Each plot consisted of 24 quails, totaling 480 birds. Characteristics were evaluated during treatments (body weight, egg production, viability, number of days to cease and number of days to return the egg production) and after application (performance characteristics and quality bark). The differences between treatments were compared by Scott-Knott test (5%). The treatments consist of wheat bran and feed with high levels of zinc provided worst average production of eggs and feed conversion per dozen eggs. There was no effect of treatments on the quality characteristics of eggs. The supply of only corn or only corn and soybean meal can be used as methods of forced molting for Japanese quails to replace fasting.
