Honamlı Erkek Oğlaklarında Büyüme, Besi Performansı ve Karkas Özelliklerine Doğum Tipinin Etkisi

Abstract

The aim of this study is to determine fattening performance, slaughter and carcass characteristics of single and twin male Honamlı kids raised under semi-intensive conditions. In the study, 90 day-olds (weaned at the age of 75 days and the 15-day period of adaptation to feeding), 10 single and 10 twin Honamlı male kids were fattened for 56 days and all kids were sent for slaughter at the end of the fattening period. Final average live weights were found to be 34.4 kg and 30.4 kg for single and twin kids. Average daily live weight gain during fattening was 203 g for single kids and 231 g for twin kids. Hot carcass weights obtained after slaughter were 14.47 kg and 12.43 kg; dressing percentages calculated based on empty body weight were determined to be 52.46% and 51.11% for single and twin kids, respectively (P>0.05). Cold carcass weights were determined to be 14.19 kg and 11.17 kg for single and twin kids, respectively; cold carcass yields calculated based on empty body weight were determined to be 51.53% and 50.04% for single and twin kids. The surface areas of M. longissimus dorsi (MLD) were found to be 13.39 cm2 and 12.43 cm2, respectively. Withers height, rump height, body length, chest girth, and nose length of single kids were relatively higher compared to twin kids at the end of the fattening period.
