Effect of Different Protein Levels for Finishing Period on Fattening Performance and Carcass Traits in Native Turkish Geese

摘要

This study was carried out to investigate the effect of the different protein levels on the body weight gain, feed consumption, feed efficiency and carcass traits in the finishing period in native Turkish geese. In the experiment, 10 weeks of age native Turkish geese were used. A total 48 geese were divided into three experimental groups, 16 geese for each. They were fed with the rations containing 10, 12.5 and 15% crude protein and 2900 kcal kg-1 metabolic energy. Body weights of the geese were found to be similar in the treatment groups 1, 2 and 3 (p>0.05). There is no significantly difference among the treatment groups in the cases of body weight gain. The most significant differences were observed in abdominal and intestinal fat weights among the treatment groups (p<0.05-0.01). Warm carcass percentage, neck, back and wing weight were determined to be significantly heavier in group 1 (p<0.05). Leg, back, intestinal+abdominal fat percentages were significant among the treatment groups (p<0.05-0.001). It was detected that high protein levels gave no advantage in finishing period in the native Turkish geese.
