EFECTO DEL VOLTEO Y TRANSFERENCIA A LA NACEDORA EN LA INCUBACIÓN ARTIFICIAL DE HUEVOS DE CODORNIZ JAPÓNICA

Abstract

The intention of this study was to investigate the effects of flipping and transfer to the hatchery in the artificial incubation of japan quail eggs (Coturnix coturnix japan) including transfer weight to hatcher, transfer time - hatching, hatching percentage and embryonic death. A total of 288 eggs were randomly distributed in 3 incubators (Inc), each referred to as treatment (Trt) and were exposed to identical turning characteristics (frequency, angle and duration), in contrast to the days of transfer (13^Inc3, 14^Inc2 and 15^Inc1).The results demonstrated through the Tukey test (0,05), heterogeneous groups when contrasting the average weight of the egg in the hatchery transfer in each of the incubators (Inc¹ ¨10,94 gr¨, Inc² ¨10,78 gr¨ and Inc³ ¨11,21 gr¨). The different transfer days manifested 3 kinds of hatching; Early (Inc² ¨ -24 h¨), on time (Inc¹ ¨0 h¨) and late (Inc³ ¨+24 h¨), the latter recorded a 120-hour birth window, unlike the first They recorded 48 hours, respectively. The hatching percentage was adequate with transfers close to hatching (Inc¹ ¨90,63¨, Inc² ¨93,75¨ and Inc³ ¨79,17¨), as well as in the number of embryonic deaths, however, the same was not reflected in the last incubation stage when the reduction of the day of transfer to the hatchery (day 13) increased embryonic mortality.
