The analysis of raw nutrients in M. longissimus of a large sample of the current German pig population demonstrates a stabilisation of protein, fat and water content. Thus, the trend towards an increase of water with decreasing protein content observed for the last decades came to a halt. However, the intramuscular fat content remains on a low level of about 1.0%. Breeds with potential to increase the IMF content (e.g. Duroc) will not widely be used in future due to disadvantages in slaughter performance. Moreover, Duroc-crossbred pigs are not generally characterised by improved IMF content. Drip loss varies strongly between breeds and crosses with advantages of Duroc and Duroc-derived crosses. There is a trend towards a better sensory evaluation of the M. longissimus in these animals. Rare breeds like German Saddleback have the potential to improve the sensory quality of pork. However, their low performance in economically important traits will restrict their use to local niche porduction. © Verlag Eugen Ulmer, Stuttgart. Source

In 99 farrowing sows the number of teats and teat canals per functional teat were counted through milk flowing during milking. The rearing performance described by litter and single weight at day 21 of lactation, were related to number of canals per teat and the share of one canal teats. Significant relations were not found. © Verlag Eugen Ulmer, Stuttgart. Source

This study of winter wheat varieties grown under environmental conditions in the Brandenburg region focuses on the following question: How do winter wheat varieties differ in terms of yield stability, yield capacity and response to dry weather conditions? To answer this question, we drew on the results from variety trials carried out over a period of several years and at several different locations in the German Federal State of Brandenburg and analysed different varieties of winter wheat according to the following bio-statistical parameters: ecovalence, linear regression and floating checks. We then estimated different factors affecting yield variability and analysed the response of varieties to different weather conditions according to the climatic water balance. The study showed that environmental factors had the greatest influence on yield variability, whilst variety had a significantly smaller effect. Nevertheless, there were considerable differences between varieties with regard to yield capacity, yield stability and response to environmental conditions. The results are equally important for variety testing and evaluation and plant breeding as well as for agri cultural practice. They provide information about the variable, environment-dependent traits of varieties and through the development of an evaluation scheme, can help breeders to select optimum varieties and make recommendations of suitable site-adapted varieties to farmers.

The supplementation of extruded linseed on growth and meat and fat quality of castrated male pigs has been investigated in this experiment. Pigs were fed with concentrate pellets without supplement (control), added with 2.5% extruded linseed (experimental group 1) or 4% extruded linseed (experimental group 2) during the finishing period. Growth and, meat and fat quality were not affected by extruded linseed feeding. Fat of muscle and back fat in pigs fed linseed deposited dose dependently more n-3 fatty acids. The ratio n-6 to n-3 was decreased in experimental groups. The processing quality of back fat could be reduced. Source
