Absztrakt

Sixteen crossbred female kids, (Hungarian Milking Brown×Alpine) F1 (n=8) and (Hungarian Milking Brown×Boer) F1 (n=8), were selected from the same farm. The kids were scanned by Computed Tomography to evaluate and compare the body composition of crossbred progenies. The area of fat, muscle and bone tissues were estimated according to the x-ray densities from the 10 mm thick scans. The distance were 20 mm between slices, therefore forty-sixty slices were produced by individual, depending on the longness of vertebral column. The area of tissues were recorded in mm2 and analysed by GLM using live weight as covariant (LSD-test; P<0.05) and partial correlation corrected for body weight. In Alpine crossbreds the average area of fat tissue was 64.6 thousand mm2, while in Boer progenies it was 71.1 thousand mm2. The area of muscle tissue in Alpine crossbred kids was 290.4 thousand and 372.0 thousand mm2 in Boer crossbreds, which difference was significant. The average area of bone tissue was similar in two crossbreds groups. In Alpine F1 none of the partial correlation among fat, muscle and bone tissues became significant. In Boer F1 the correlation between muscle and bone tissues was strong and significant. The Boer had stronger and significant effect on body tissue composition comparing to Alpine breed concerning to meat production.
