Resumo: | ABSTRACT The effects of three egg-turning regimes during the pre-incubation storage period on egg weight loss, hatchability, embryonic mortality, chick weight at hatching and incubation length of red-legged partridge (Alectoris rufa) compared with unturned eggs were investigated. Two hundred eggs were allocated to four 50-egg batches stored at 15ºC and 80% RH that being turned one, four and 24 times a day or remaining unturned, respectively. Eggs were incubated at 37.8ºC and 55% RH during the first 21 days and at 37.5ºC and 75% RH until hatching. Fertility was 70.5% and a good hatchability performance was obtained, characterised by 81.6% hatchability of fertile eggs, and weight losses of 0.78% during storage and of 10.04% during the first 21 days of incubation, 13.6 ±0.1 g hatchling weight, and incubation length of 23.45 ± 0.07 days (mean ± SEM). Hatchability, embryonic mortality developmental stage, egg weight loss during storage and incubation, hatchling weight and length of the incubation period were not affected by the turning frequency or the absence of turning during storage. Higher hatching synchrony was observed for eggs turned four times a day compared with unturned eggs and eggs turned once a day. In conclusion, turning red-legged partridge eggs during medium-term storage periods does not improve egg viability compared with unturned eggs. |

Two hundred eggs were allocated to four 50-egg batches stored at 15ºC and 80% RH that being turned one, four and 24 times a day or remaining unturned, respectively. Eggs were incubated at 37.8ºC and 55% RH during the first 21 days and at 37.5ºC and 75% RH until hatching. Fertility was 70.5% and a good hatchability performance was obtained, characterised by 81.6% hatchability of fertile eggs, and weight losses of 0.78% during storage and of 10.04% during the first 21 days of incubation, 13.6 ±0.1 g hatchling weight, and incubation length of 23.45 ± 0.07 days (mean ± SEM). Hatchability, embryonic mortality developmental stage, egg weight loss during storage and incubation, hatchling weight and length of the incubation period were not affected by the turning frequency or the absence of turning during storage. Higher hatching synchrony was observed for eggs turned four times a day compared with unturned eggs and eggs turned once a day. In conclusion, turning red-legged partridge eggs during medium-term storage periods does not improve egg viability compared with unturned eggs. |
