Influence of the age on the productivity of family flock of hybrid Arbor Acres chickens

Abstract

In this paper analyzed productive and reproductive results of family flock on the farm "Chicken product" LTD, Mladenovac, Serbia, from 23 to 66 weeks of age of natural exploitation, on expert exploitation. According the results we can conclude that production results are 189.45 consume eggs by a hen 174.55 eggs for incubate; 135.38 one day old chickens by a hen; Average daily spend of food by a chicken was 162.53 grams, by a egg for incubation 315.43 grams and by a one day old chicken 406.69 grams.

U radu su prikazani i analizirani ostvareni proizvodni, odnosno reproduktivni rezultati roditeljskog jata teškog linijskog hibrida Arbor Acres gajenog na farmi "PILE PRODUKT" DOO - Mladenovac od 23. do 66. nedelje starosti. Maksimalan intenzitet nosivosti roditeljskog jata postignut je u 34. (82,76%) i 35. (82,53%) nedelji, a najbolja izvodljivost (leženost) jaja ostvarena je između 37. i 38. nedelje starosti (preko 88% od broja uloženih jaja). Posle tog perioda intenzitet nosivosti i procenat izvodljivosti jaja su se postepeno smanjivali, a utrošak hrane po grlu, proizvedenom jajetu i jednodnevnom piletu povećavao.
