Kapalı ve Serbest Gezinmeli Üretim Sistemlerinde Doğal ve Yapay Kuluçka ile Üretilen Kazların Ekonomik Değerlendirmesi

Abstract

This study executed the economic return of naturally and artificially hatched geese in intensive and free-range production systems at different fattening periods. The animal material was consisted of 216 goslings which were naturally and artificially hatched from the eggs collected from back-yard. Goslings and feed was the highest share of variable expenses. Highest net profit from live and carcass sales was obtained from geese which were artificially hatched and reared in intensive (YK) and free-range (YSG) systems until 14, 16 and 18 weeks of age. Live sale relative profit was found higher at 14 weeks in YK and YSG groups. Relative profit of carcass sales in YSG and YK groups at 14 and 16 weeks; and YK group at 18 weeks. As a conclusion, when we consider feed consumption, feed conversion ratio and probable mortality at older ages-related to metabolic problems; 14 weeks seemed as the optimal slaughter age and economic return for the naturally and artificially hatched geese which were reared in intensive and free-range systems.
