In order to make comparative examination of lying eggs capacity, an experiment was carried out. It lasted from 19th to 63rd week of age. Examination included two hens’ hybrids Shaver 579 and Hisex Brown. For both examined hybrids, similar conditions of growing and feeding technology were provided. For the whole period of egg production, average values and variability of weekly number of eggs per hen for Shaver 579 was 5.72, and Hisex Brown had a little higher weekly egg production-5.99 eggs. The greatest part of eggs per hen was in 11th week of production in both examined provenience. In both examined light line hybrids, statistically significant difference was determined between age of hens and average weekly egg production per hen. U cilju uporednog ispitivanja nosivosti lakih linijskih hibrida kokoši, izveden je ogled u trajanju od 19. do 63. nedelje starosti. Ispitivanjem su obuhvaćena dva hibrida kokoši: Shaver 579 i Hisex Brown. Za nosilje, oba ispitivana hibrida, bili su obezbeđeni slični uslovi tehnologije gajenja i ishrane. Za ceo period produkcije jaja, prosečne vrednosti i varijabilnosti nedeljnog broja snešenih jaja po useljenoj nosilji za Shaver 579 je iznosio 5,72, dok je nešto veću prosečnu nedeljnu proizvodnju jaja imao Hisex Brown 5,99 jaja. Najveći broj jaja po useljenoj kokoši bio je u 11. nedelji proizvodnje kod obe ispitivane provenijence. Kod oba ispitivana laka linijska hibrida utvrđena je statistički vrlo značajna zavisnost između uzrasta nosilja i prosečne nedeljne proizvodnje jaja po useljenoj kokoši. |
