Keywords:
poultry, Oravka, egg production, egg weightAbstract
Our work describes the results of egg production and egg weight of hen’s breed
Oravka in years 2004 - 2008. Observation of production parameters of hen’s breed
Oravka realised in special poultry house for controlled breeds of poultry at
University Experimental Farm in Kolíňany. In analyzed period 2004 to 2008 we
observed flock of breed Oravka with ten females and one male. This poultry flock
was selecting from young birds per year. The egg production we evaluated as
average number of eggs for accelerated 7-month laying period (1 month - 30 days).
The eggs were weighed individually from every hen for period 10 days in each
month. On basic of achieved results we observed progressive increase of egg
production and egg weight. The egg production of breed Oravka increased about
3.10 eggs/hen (2.06 %) between years 2004 and 2008. Massive improvement we
recorded at parameter of egg weight (3.30 g - 6.30 %) in analyzed period. The
selection programme of breed Oravka will target the increase of egg production and
egg weight in accordance with standard of breed (egg production 180 - 200 eggs,
egg weight 58 g).
