The aim of the study was to examine the influence of the physical form of oat grain (whole, crushed or ground grain) on the fattening results, feed conversion and carcass quality of the W-33 strain of White Kołuda (Biała Kołudzka®) geese. A total of 90 hatchlings (45 ♂♂ + 45 ♀♀) were randomly selected for the experiment. All geese were fed in the same way until the age of 14 weeks, receiving KB-1, KB-2 and KB-3 compound feeds in the amount of up to 300 g/individual/day and grass forage ad libitum. At the end of the 14th week, the geese were divided into three feeding groups (15 ♂♂ and 15 ♀♀ in each) and in the period from weeks 15 to 17, a total of 21 days, they were fed only hulled oat grain of the Rajtar cultivar. Group I received whole grain, group II crushed grain, and group III ground grain. After the fattening was completed, 5 male and 5 female geese from each of the three experimental groups were selected for slaughter analysis. The birds receiving whole oat grain had the highest body weight, weight gain from the 15th to the 17th week of life, feed conversion and dressing percentage. Male geese had higher body weight, higher muscle tissue content, and lower adipose tissue content than females (P≤0.01). The two sexes did not differ significantly in dressing percentage or content of abdominal fat.
