Comparison of the performance of the parental combination of geese ESKILDSEN SCHWER and their progeny during three laying cycles
 ZIGÁČEK, Ladislav
Abstract The aim of the bachelor thesis was to compare the production traits of goose parental combination ESKILDSEN SCHWER and their progeny obtaining from the poultry performance testing during three laying cycles. The tests were made by International Poultry Testing Station in Ústrašice and methodology was based on the guidelines for the implementation of poultry performance testing. Parental test consisted of rearing parents until the age of 210 days, the laying preparation period of 211?285 days, the rearing period at duration 160 days and from two fattening progeny tests lasting for 56 and 112 days. Higher live weight at 1 day, 56 day and 210 days of age during parental test was found out at gangers compare to geese. The higher number of eggs in the initial stage (66.3 eggs) and number of hatched goslings (46.4 heads) were found out at two-year-old geese. The above-average temperatures in May caused premature drop of lying at three-year-old geese. The highest breast muscle weight (430 g) at 1st fattening progeny test at 56 days of age was at three-year old geese. It was only about 14 g higher in comparison with progeny of two-year-old geese and about 30 g higher in comparison with one-year-old geese. The highest weight of breast muscle was found out at three-year-old geese at the 2nd fattening progeny test too (493 g), followed by progeny of two-year-old geese and one-year-old geese. The highest weight of breast muscle (671 g) was found out at 112 days of age at the 1st fattening progeny test at three-year-old geese. The lowest weight was at progeny of two-year-old geese. The highest breast muscle weight (746 g) was achieved at progeny of three-year-old geese at the 2nd fattening progeny test. They were followed by one-year-old geese and two-year-old geese.
