Lohmann Brown chickens falls into hybrids with increased productivity of eggs with the genetic potential to produce eggs up to 320 eggs a year per hen and are grown in all climatic conditions.The purpose of this research is to determine how to meet the genetic potential for egg production in chickens hybrid Lohmann Brown, compared with the production results of eggs from this hybrid, derived by applying intensive technology of farm Agripro in Valandovo R. Macedonia in production in year 2014 and 2015. Research is conducted on a sample of 20,500 laying hens in year 2014 and 21,000 laying hens in year 2015.
A comparative analysis from the conducted survey revealed that deviation from the genetic potential for the production of eggs in the hybrid chickens Lohmann Brown, compared with production potential of eggs from this hybrid, indicates that in 2014 statistical variation coefficient amounts 18 eggs or 5.62% (VC%), while for 2015 was 21.5 eggs or 6.72% (VC%) annually per laying hens. The average deviation for both production years 2014/2015 amounts to 19.75 eggs and 6.17% annually (VC%) per laying hens. From the results we can conclude that the deviation from the genetic potential for the production of eggs in this hybrid of chickens is minimal, because the production is organised in conditions of intensive technology recommended by the manufacturer of the hybrid Lohmann Brown.
