Abstract

This study was performed to evaluate effects of different holding temperatures and storing periods during the pre-incubation period on egg hatchability of hens egg in broiler breeders. For the treatments 1(T1)~7(T7), which were stored fur 1(T1) to 7 days(T7) before egg incubation, respectively. There were three replicates per treatment and forty eggs per replicate. This study was performed twice, which were 40(Summer) and 50 weeks of age(Autumn) in broiler breeders. Storing ambient temperature of egg, egg weight, at 0 and 18 days during incubation, fertility, hatchability and embryo mortality were examined. Average hatchability was rapidly decreased only in Summer. Although it was not significantly different in Autumn. This experiment was concluded that storing periods of hatchery egg was influenced hatchability, especially in high ambient temperature conditions(Summer, above $25^{\circ}C$ ). In conclusion, we found out that optimum hatchability can be achieved with a storage temperature of 13 ~$19^{\circ}C$ for broiler breeder eggs stored for up to 7 days.

본 연구는 육용종계 종란의 보관조건에 따른 입란전 보관 기간이 부화율에 미치는 영향을 구명하고자 실시하였다. 산란 후 입란전 종란보관기간을 달리한 7개 처리, 즉 1일 보관 (T1)에서부터 7일 보관(T7)으로 시험을 실시하였다. 각 처리당3개의 반복을 두어 반복당40개의 종란을 공시하였다. 본 연구는 종계의 주령이 40주령인 여름과 50주령인 가을에 실시하였다. 저장온도에 따른 입란전 종란의 저장기간동안 발육후 18일째의 입란대비 감량률, 수정률, 부화율 및 발육중배자 사망률을 조사하였다. 시험결과 종계의 주령이 40주령인 여름철에는 보관기간이 길어짐에 따라 부화율이 급격하게 하락하여 3일 이상 보관시에는 1~2일 보관보다 낮아 통계적 유의차가 인정되었다(P<.05). 종계의 주령이 50주령인 가을철에는 보관기간에 따른 부화율의 차이는 인정되지 않았다(P<.05). 결론적으로 외기 환경온도가 높을 때(여름철, 25 $25^{\circ}C$이상) 3일 이상의 종란보관은 부화율에 큰 영향을 미치며, 1주일 이상 보관시 부화율 저하를 방지하기 위해서는 13~$19^{\circ}C$의 온도에 보관하는 것이 바람직함을 입증하였다.
