Effects of feeding systems on yield and performance of Linda geese (Anserinae sp.) in hot climatic conditions

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