Hatchability of Broiler Hatching Eggs with Different Egg Shape Index

Abstract

In this paper are presented results obtained in incubation of broiler hatching eggs with different egg shape index. A total 450 eggs originated from parent flock Cobb 500 were separated according to egg shell index values (IO) into one of three groups: T (IO <73.00%), N (IO 73.00-76.00%) and O (IO >76.00%). Average values of egg shell index in groups T, N and O (78.51; 75.59 and 72.85%, respectively) were statistically different (p<0.01). Obtained results indicated that hatchability of set (90.0; 90.0; 90.7%, respectively) and fertilized eggs (91.8; 93.1, 92.5%, respectively) showed relatively comparable values among groups with different egg shell index (p>0.05).

U radu su prikazani rezultati istraživanja uticaja indeksa oblika jaja na pokazatelje inkubacije priplodnih jaja teškog linijskog hibrida Cobb 500. Ukupno 450 jaja razvrstano je, u zavisnosti od vrijednosti indeksa oblika jaja (IO), u jednu od tri grupe: T (IO <73,00%), N (IO 73,00-76,00%) i O (IO >76,00%). Prosječan indeks oblika značajno se razlikovao (p<0,01) među grupama T, N i O, a iznosio je 78,51; 75,59 i 72,85%, redom. Na osnovu dobijenih rezultata može se zaključiti da je valivost uloženih (90,0; 90,0; 90,7%, redom) i oplođenih jaja (91,8; 93,1, 92,5%, redom) bila relativno ujednačena (p>0,05) među grupama sa različitim indeksom oblika jaja.
