Abstract
ABSTRACT Two experiments were conducted to evaluate combinations of different storage periods and temperature of hatching eggs of breeder quails in two stages of the production cycle (24 and 43 weeks) on hatchability, quail neonate quality, and Bursa of Fabricius characteristics. In each experiment, a total of 1.050 Japanese quail eggs were incubated in a randomized block design in a factorial arrangement of 2 × 5 × 2, with two breeder ages (24 and 43 weeks), five storage periods (one, [...]
Highlights
Brazilian quail farming has presented high growth over recent years
The results regarding the hatching:fertile egg ratio (Table 1) showed that there was no interaction among period, storage temperature, and breeder age (P>0.05)
Breeder age had an effect on this relation (P
Summary
The main factors that have driven this development are the low investment needed for the infrastructure, little space necessary for the activity, sexual precocity and good laying rate of the birds, and the low feed intake (Teixeira et al, 2013). Another factor is that major commercial egg-producing companies are entering the market as quail-egg producers. To ensure the quality of neonate quails on the market, the characteristics of this species need to be studied, along with factors that affect embryonic development and consequent yield in the incubator. According to Araújo et al (2015), to this day, the methods used for incubation of fertile eggs by breeding quails are based on parameters determined through studies on broiler breeders
