This study evaluated the effects of various types of feeding on fattening period and performance of Linda geese. Feeding patterns consisted of concentrate feed-based intensive and pasture feed-based semi-intensive. A total of 150 goslings aged three days were divided into two groups, each consisting of three replications. All groups were given rations containing 23% crude protein and 3100 kcal/kg ME in weeks 0–6, and rations containing 20% crude protein 3100 kcal/kg ME between weeks 7 and 17. After the seventh week, the feed for the semi-intensive group was diluted with 20% barley and from the tenth week, this group started to graze on pasture. Live weight gain of the two groups was similar, although geese kept indoors consumed more concentrate. Feed protein digestion of geese was similar in the two feeding types. Digestion-related visceral weight in the pasture-supplemented group increased, whereas carcass weight decreased. Growth curves were used to estimate the age of Linda geese to the end of the fattening period. The average slaughter age was the fourth and fifth months, as indicated by Von Bertalanffy, Logistic, and Gompertz growth models, which used the data from the third week. Concentrate feeding enabled Linda geese to reach earlier higher slaughter weight, although it was not considered economical. Although averages of bodyweight gain over the trial appeared slightly better in the concentrate-based intensive group, the results revealed that concentrate feed supplement and pasture may be the best and most economical form of feeding for Linda geese.
