Effect of Hatching Month, Egg Physical Characters and Storage, on Embryonic Mortality in Japanese Quails ( Coturnix coturnix japonica )

To study the effect on the embryonic mortality until the 17th day (M17) and between the 18th and 21st day (M21), of month of lay (MP), egg weight (PH), shell color (CCH), shell sheen (BRH) and time of storage (TA), analyses of variance were realized assuming a binomial distribution of the data, usin...

Zusammenfassung:To study the effect on the embryonic mortality until the 17th day (M17) and between the 18th and 21st day (M21), of month of lay (MP), egg weight (PH), shell color (CCH), shell sheen (BRH) and time of storage (TA), analyses of variance were realized assuming a binomial distribution of the data, using 1403 records for M17 and 845 for M21 of five incubations of eggs gathered from 120 experimental quails of the Poultry Section - Laboratory (UCV). Water and food were offered ad libitum. Was found mortality averages of 29,9 % and 35,04 % for M17 and M21, respectively. The month of higher (P
