Untersuchungen zu Einfachgebrauchskreuzungen beim Merinolandschaf
(2013) Henseler, Stefanie; Bennewitz, Jörn
The present study examined the meat and carcase quality of lambs slaughtered in the German federal state of Baden-Württemberg in order to determine the sire breeds most suitable for the Merinolandschaf, a Merino land race. For this purpose, rams of the meat breeds Charollais, Ile de France, Blackheaded sheep, Suffolk and Texel were bred to the widespread Merinolandschaf in order to produce cross bred lambs. In addition, rams of the Merinolandschaf were used to produce purebred lambs. The lambs were raised on seven farms, then fattened at one farm and slaughtered. 1600 lambs were used to evaluate meat quality, fattening performance and yield at slaughter. 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 net gain from fattening of the Texel sheep surpassed all other crossbreeds. In regard to yield from slaughter, crossbreeds with Charollais, Ile de France and Texel showed improvement in development of haunches and classification. Texel crossbreed ranked highest in respect to meat area of the chops. The parameters determining the quality of the meat – drip loss and loss by cooking – were lowest for pure Merinolandschaf. High shear force was necessary for meat of Suffolk and Texel crossbreeds, whereas Charollais crossbreed showed the lowest value for this parameter. 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‘s meat. In addition, it was shown that lamb’s meat from the German federal state of Baden-Württemberg differs significantly from lamb’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 ranking of breeds can differ.
Zweinutzungshuhn – was ist das? Umfrage unter Landwirt*innen und Geflügelhalter*innen in Deutschland 2022

To comply with the ban on chick culling that has been in effect since January 2022, the Federal Ministry of Food and Agriculture proposes three alternatives, including the hatching of dual-purpose chickens. In addition to the breeding and economic challenges of establishing dual-purpose animals in the value chain, the inconsistent understanding of what a dual-purpose chicken actually is and how its characteristics can be successfully communicated to consumers are seen as challenges. The goal of this working report is to present what a dual-purpose chicken is and what understanding farmers have of it. The German nationwide online survey among farmers and poultry farmers regarding the understanding and future of dual-purpose chickens was conducted in autumn 2022 as part of the EIP-Agri project "ZweiWert." The EIP project titled "Building Value Chains for Dual-Purpose Chickens in Baden-Württemberg" (ZweiWert) is funded by the Ministry of Food, Rural Areas and Consumer Protection of Baden-Württemberg from 01/2022 to 12/2024. Project partners include the Naturland Association of Baden-Württemberg, several departments of the University of Hohenheim, and many partners from agricultural production and marketing.
