Ultrasound measurements of backfat thickness and Musculus longissmus dorsi thoracis et lumborum (MLD) depth at the weaning on karacabey merino,Karya and kıvırcık lambs [Karacabey merinosu,karya ve kıvırcık kuzularda sütten kesim döneminde kabuk yağı kalınlığı ve Musculus longissmus dorsi thoracis et lumborum (MLD) derinliğinin ultrason Ölçümleri]

The experiment was conducted to determine the ultrasonic measurements of backfat thickness and musculus longissmus dorsi thoracis et lumborum (mld) characteristics at weaning. ultrasonic measurements of mld in karacabey (258),karya (168) and kıvırcık (241) were performed in 667 lambs born in 2012-2013 lambing season. least square means for backfat thickness,skin+fat thickness,muscle depth,average daily gain and weaning weight,at the mean age of 115 days,were 0.31 cm,0.55 cm,2.09 cm,229.57 g and 29.20 kg respectively. results for backfat thickness,skin+backfat thickness,muscle depth of mld and average daily gain and weaning weight were compatible with differences for live weight among the breeds. all the correlation coefficients between ultrasound measurements of mld properties,used to determine the effect of conformation and fatness status,and live weight were positive and statistically significant. © 2014,kafkas university. all rights reserved.
