The scientists of State Poultry Research Station, National Academy of Agrarian Sciences of Ukraine, using the national gene pool of chickens, created a dual purpose hybrid producing both high quality meat and eggs. The purpose of this study was to present a detailed analysis of egg production in the new hybrid compared with the original forms. Egg production and its intensity in the hybrid and purebred hens have been evaluated by periods (weekly, monthly, at 40 and 52 weeks of life). As a result, the components of egg production (age of onset of laying and its peak, the rate of increase, average daily growth and relative growth) and egg production indices (intensity, uniformity, strength, stability) were calculated. Substantially all of the studied parameters indicated the advantage of hybrids over the original forms. Earlier attainment of puberty (by 2.2 weeks), a more intensive increase of egg production (by 3,3-4,2%), the enhancement of its average intensity (by 4,6-9,8%) allowed to obtain from the hybrid hens by 10-22 eggs more than from the original forms per one year of life. The high correlation between the stability index and total egg production of the hybrids (0.81) shows a significant productive potential level of these hens. |
