| Popis: | This study was carried out to determine the effects of storage time, position and prewarming of hatching partridge (Alectoris graeca) eggs on embriyo deads. In this research, 1394 partridge eggs were used. The preincubation egg storage groups were 1-7, 8-14, 15-21 and 22-28 days. Each principal group of totally four egg storage groups was divided into three egg position groups which were 45° rotation twice a daily, not turning egg (-) and turning egg (+) daily acording to egg position. Each egg position group was separated three prewarming groups prewarmed before storage (DB, db, Db), prewarmed before incubation (KÖ, kö, Kö) and without prewarmed (K, k, Kk). All the eggs were storaged in the egg storage rooms with 12.8 C temperature and 70-75 % relative humidity. The egg position group which were turning egg (+) was found be better than other egg position groups from the point of view of the embriyo deads in the 8-J4 storage time (p |
