The aim of study was to compare performance and meat quality between 2 genotypes of geese (Czech Goose CG and Novohradska Goose NG) depending on sex. 1 day old goslings were weighed and divided to 4 groups according to genotype and sex. Weighing and the evidence of feed consumption was conducted weekly. 8 goslings of each group were slaughtered at the age of 56 days, selected slaughter parameters and chemical composition of meat were determined. Significant interactions between genotype and sex were found out in live weight at the age of 1 day of goslings (P < 0.001), final live weight (P < 0.001), daily weight gain (P < 0.001), feed conversion ratio (P < 0.001) and hot carcass weight (P < 0.001). Protein content in meat was significantly (P = 0.025) affected by genotype, with higher values in CG. Ash content was significantly (P = 0.029) influenced by sex and higher content was observed in males.
