Incubation of bird eggs on family farm

Istražene su razlike u inkubaciji između kokošjih i nojevih jaja. Inkubirano je ukupno 4041 kokošje jaje u 32 turnusa i 47 nojevih jaja. Jaja su podrijetlom sa obiteljskih gospodarstava iz istočne Slavonije. Inkubacija jaja obavljena je u inkubatoru vlastite proizvodnje (Lađa 54 V 18 i Lađa 3200 V 1000). Prikupljanje jaja za inkubaciju i inkubacija je trajala pet mjeseci. Opisani su postupci prikupljanja i rukovanja s jajima prije i tijekom inkubacije. Od ukupnog broja uloženih jaja u inkubator (47) izleglo se 23 nojića ili 48,94%. Postotak neoplođenih jaja bio je 23,4%, dok je uginulih zametaka bilo 27,66%. U prosjeku, izvaljeno je 69,9% jednodnevnih pilića od ukupno nasađenih jaja. Utvrđena je visoka varijabilnost izvaljenih pilića (od 52,22% do 83,85%) uslijed različitih dobavljača i načina uzgDifferences in incubation between hen and ostrich eggs were investigated. A total of 4041 hen eggs were incubated in 32 shifts and 47 ostrich eggs. The eggs originate from family farms in Eastern Slavonia. Incubation of eggs was performed in an incubator of own production (Boat 54 V 18 and Ladja 3200 V 1000). Collection of eggs for incubation and incubation lasted five months. Procedures for collecting and handling eggs before and during incubation are described. Of the total number of eggs placed in the incubator (47), 23 ostriches or 48.94% hatched. The percentage of unfertilized eggs was 23.4%, while the number of dead embryos was 27.66%. On average, 69.9% of day-old chicks hatched from the total number of eggs laid. High variability of hatched chickens (from 52.22% to 83.85%) was found due to different suppliers and methods of rearing. Better hatchability by about 20% was found in hens compared to ostrich eggs
