Effects of different fattening systems on slaughter and carcass traits of male Hemsin lambs

Abstract

The objective of this study was to investigate the effect of different fattening systems on the slaughter and carcass traits of male Hemsin lambs. Hemsin lambs were divided into three groups; extensive, semi–intensive, and intensive. Lambs in the extensive group were grazed on pasture. Lambs in the semi-intensive group were grazed on pasture and also fed with concentrated feed. The concentrated feed was given to lambs in the intensive group. The experiment was conducted for 90 days. A total of 24 lambs (8 fattening lambs from each group) were slaughtered. While slaughter weights of extensive, semi–intensive, and intensive fattening groups were 32.71, 41.38 and 41.49 kg, respectively (P<0.001), hot carcass weights were 14.24 for extensive group, 19.21 for semi–intensive group, and 20.44 kg for intensive group (P<0.001), and also cold carcass weights were 13.73 for extensive group, 18.79 for semi–intensive group, and 19.94 kg for intensive group (P<0.001). Results of this study revealed that there was generally no statistically significant difference between intensive and semi-intensive groups in terms of slaughter and carcass traits. The results of this study revealed that semi-intensive group can be said to be more appropriate for fattening the male Hemsin lambs

Farklı besi sistemlerinin Hemşin erkek kuzularında kesim ve karkas özelliklerine etkisi

Abstract

Bu araştırma, farklı besi sistemlerinin Hemşin erkek kuzularında kesim ve karkas özelliklerine etkisinin belirlenmesi amacıyla yapılmıştır. Araştırmada ekstansif, yarı entansif ve entansif olmak üzere 3 değişik besi grubu oluşturulmuştur. Ekstansif grup merada otlatılmıştır. Yarı entansif gruba meraya ilaveten konsantre yem verilmiştir. Entansif gruba ise konsantre yem verilmiştir. Araştırma 90 günde tamamlanmıştır. Ekstansif, yarı entansif ve entansif beside her grupta 8, toplamda 24 kuzu kesilerek, kesim ve karkas özellikleri incelenmiştir. Ekstansif, yarı entansif ve entansif beside kesim ağırlığı sırasıyla 32.71, 41.38 ve 41.49 kg (P<0.001), sıcak karkas ağırlığı 14.24, 19.21 ve 20.44 kg (P<0.001), soğuk karkas ağırlığı 13.73, 18.79 ve 19.94 kg olarak belirlenmiştir. Sonuç olarak; yarı entansif ve entansif gruplar arasında genel olarak kesim ve karkas özellikleri bakımından istatistiki bir fark bulunmamış olup, yarı entansif besi yapılan grubun daha uygun olacağı söylenebilir
