Vliv pohlaví na produkční znaky hybridů kachny pekingské
KOSTRŮNKOVÁ, Gabriela
The aim of the master thesis was to compare the performance traits of Pekin duck - three hybrid combinations - Cherry Valley, Orvia and Grimaud that were fed to the age of 44 days. The test was performed by the International Poultry Testing Station in Ústrašice. The methodology was based on the guidelines for the implementation of poultry performance testing. Hybrid Cherry Valley achieved the highest fertility of hatching eggs (96%), weight of hatching eggs (88,1 g), live weight at age of 1, 21, 35 and 44 days (age of 44 days - 3 315 g), average daily weight gain (74,1 g), carcass weight (2 217 g) and weight of the breast muscles with skin (636 g). Hybrid Orvia showed the lowest feed conversion ratio ((2 165 g/1 kg of weight gain) and mortality and the highest weight of leg muscle with skin (551 g). Drakes showed higher live weight, average daily weight gain, weight of the breast and leg muscles with skin and lower weight of abdominal fat .

The aim of the bachelor thesis was to evaluate performance parameters for hybrid combinations of the Pekin duck hybrid Orvia, Grimaud and Cherry Valley. The tests were made by International Poultry Testing Station in Ústrašice. Test was consisted of fattening progeny tests lasting 44 days. Hybrid Cherry Valley achieved the highest live weight at 44 days of age (3 315 g) and the highest average daily gain (74.1 g) too. Hybrid Orvia showed the lowest feed consumption per 1 kilogram gain (2 164 g) and the lowest mortality (2.5 %). The highest live weight at 44 days of age (3 331 g), the highest carcass weight (2 160 g), the highest weight of giblets (323.7 g) and the highest breast muscle weightwith skin was confirmed at hybrid Cherry Valley.The lowest weight of abdominal fat (32.8 g) was observed at hybrid Cherry Valley too. Hybrid Orvia achieved the highest leg muscle weight with skin (534.8 g). Hybrid Cherry Valley showed only about 9.7 g lower leg muscle weight (525.1 g).
Comparison of the performance of the parental combination of geese ESKILDSEN SCHWER and their progeny during three laying cycles

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.
