The analysis of goose eggs incubation results of biracely half-breeds of geese

Abstract

In this paper we came to goose eggs incubation results of biracely half-breeds (chinese goose x danube goose), the dynamics of eggs weight loss during the incubation period, as well as the intensity of phenotypic correlation connection between eggs weight before incubation period and one day old goosling weight. Fertilization of eggs was 67,92%, hatchibility was 52,83% (out of initial number of eggs), more exactly 77,78% (out of number of fertility eggs). Average eggs weight before incubation was 151,79g, and weight of one day old goosling was 103,07g, which means that relative part of goosling in eggs weight was 67,90%. The total phenotipic correlation connection between eggs weight before incubation and hatched gooslings was found r(p)=0,987***, between eggs weight and relative part of goosling in eggs weight was established middle negative correlation connection, r(p)=0,425*.

U radu su prikazani rezultati inkubacije guščijih jaja dvorasnih meleza gusaka (kineska kvrgava x podunavska), zatim dinamika gubitka mase jaja u toku inkubacionog perioda, kao i jačina fenotipske korelacione povezanosti između mase jaja pre inkubacionog perioda i mase izleženih jednodnevnih guščića. Oplođenost jaja iznosila je 67,92%, a izvodljivost guščića 52,83% (od broja uloženih jaja), odnosno 77,78% (od broja oplođenih jaja). Prosečna masa jaja pre inkubacije iznosila je 151,79 g, a masa izleženih jednodnevnih guščića 103,07 g, što znači da je relativni udeo guščeta u masi jajeta iznosio 67,90%. Između mase jaja pre inkubacije i izleženih guščića utvrđena je potpuna fenotipsaka korelaciona povezanost - r(p) = 0,987***, a između mase jaja i relativnog udela guščeta u masi jajeta srednja negativna korelaciona povezanost - r(p) = 0,425*.
