Yarı entansif şartlarda beslenen yerli Türk kazlarının besi performansı, kesim özellikleri ve bazı kan parametreleri

Bu çalışma, yarı entansif yöntemle beslenen yerli kazların besi performansı, kesim özellikleri ve bazı kan serumu parametrelerini belirlemek amacıyla yapılmıştır. Araştırmada 3-4 günlük yaşta, karışık cinsiyette 50 adet yerli kaz civcivi kullanılmıştır. Kaz civcivleri ilk 4 hafta başlangıç, son 7 hafta büyütme yemiyle toplam 11 hafta beslenmişlerdir. Kazlar üçüncü haftanın başından itibaren 08:00-10:00 ile 15:00-17:00 saatleri arasında otlatılmışlardır. Çalışma sonunda 5 adet kaz kesilerek kesim özellikleri belirlenmiştir. Ortalama araştırma sonu canlı ağırlığı, canlı ağırlık artışı, yem tüketimi ve yemden yararlanma oranı sırasıyla; 2908 g, 33.0 g, 144.4 g ve 5.5 olarak bulunmuştur. Karkas randımanı, kanat, but, göğüs, mezenteriyel ve abdominal yağ oranı sırasıyla %63.35, 10.82, 14.31, 21.61, 1.19 ve 1.66 olarak belirlenmiştir. Serum kolesterol, total protein, albümin ve glikoz miktarları sırasıyla 123 mg/dL, 3.51 g/dL, 1.35 g/dL ve 184 mg/dL olarak bulunmuştur.

Fattening performance, slaughter traits and some blood parameters of native Turkish geese feeding by semi-intensive condition

The study was conducted to investigate fattening performance, slaughter traits and some blood parameters of native Turkish geese feeding by semi-intensive system. Fifty, 3-4 day old unsexed native gosling were used in this study. Goslings were fed totally 11 weeks (starter diet for fi rst 4 week, grower diet for 7 weeks). Beginning from the start of the third week goslings were grazed at 08:00-10:00 and 15:00-17:00. At the end of the study 5 geese were slaughtered and slaughter traits were determined. Average live weight, live weight gain, feed intake and feed effi ciency were found 2908 g, 33.0 g, 144.4 g and 5.5, respectively. Carcass, wing, leg, breast, mesenteriyal and abdominal fat ratio were found 63.35, 10.82, 14.31, 21.61, 1.19 and 1.66%, respectively. Serum cholesterol, total protein, albumin and glucose amount were found to be 123 mg/dL, 3.51 g/dL, 1.35 g/dL and 184 mg/dL, respectively.
