摘要

This study examined different breeds of sheep to determine which one is most suitable as a sire breed for the Merinolandschaf, a Merino land race, in order to produce high quality lambs for slaughter. For this purpose, the study %26quot;Suitability of Merinolandschaf for Crossbreeding%26quot; using the sire breeds Charollais, Ile de France, Merinolandschaf, Blackhead sheep, Suffolk and Texel was complemented by a sensory analysis. 105 animals were chosen from a total of 1600 lambs used in the study. These were tasted by a panel consisting of 21 persons. Results of this sensory analysis were combined with results in regard to fattening performance, yield at slaughter and quality of meat in a joint index. The sensory analysis showed that crossbreeds with Charollais, Blackhead sheep and Suffolk as well as the pure breed Merinolandschaf are well suited to production of high-quality lamb%26apos;s meat. In addition, it was shown that lamb%26apos;s meat from the German federal state of Baden-Wurttemberg differs significantly from lamb%26apos;s meat from New Zealand. There is a significant negative correlation between shear force according to Warner-Bratzler and the perceived tenderness of meat. The joint index consists of 10 economically relevant parameters, relatively weighted according to economic factors. The first rank was achieved by the crossbreed with Ile de France, followed by Texel, Suffolk and Blackhead sheep. To choose the optimal rams, i.e. the optimal sire breed, under practical circumstances, it is vital to take the conditions of the individual farm - such as marketing strategies - into consideration. With different weighting of single traits ranldng of breeds can differ.
