Over the last three or four decades, equestrian sports and breeding have developed into an important economic factor. A market analysis by the Deutsche Reiterliche Vereinigung (FN; Fédération Equestre Nationale) has shown that horses contribute approx. 5 billion euros to the gross national product of the Federal Republic of Germany. Today, about one million horses live again on the territory of the Federal Republic. For every 3 to 4 horses a workplace is created; thus, currently some 300 000 people are permanently employed in horse breeding and equestrian sports. Statistical evaluations also show that Germany occupies a leading position in Europe - both in the number of riders and in the number of horses. The achievements of German bred horses enjoy high international esteem. Horse boarding has evolved into a special source of alternative income for numerous farms - especially in the vicinity of large cities. As compared to conventional agricultural production, the main difference consists in the service character of this type of work. From mere livestock, the horse has evolved into a recreational companion; this has also brought about a change in the conditions in which horses are kept. Modern, bright and well air-conditioned stables are now much more animal friendly than earlier stables (chiefly the older tying stalls). In addition, they offer the people working in them more comfortable working conditions than in the past. In spite of sector-specific problems as they tend to occur in each line of business, horse breeding and keeping do not figure among the 'problem children' in the current agricultural policy discussion and in the associated animal welfare debate. It is obvious that the breeding and keeping of horses has been successfully adapted and integrated to their only remaining important purpose, which is for their leisure and recreational use. Source

More than 150 years ago the marsh and lowland areas in the North Sea area provided the cradle of "old" German Black and White cattle (= DSN). Also, the breeding of North American Holstein-Friesian (HF) goes back to Black and White cattle of mainly Dutch-Friesian origin. From the mid-1960s, the significantly higher milk yield of HF cattle in conjunction with the option of using improved biotechnologies (e.g. long-term storage of bovine semen or embryo transfer, etc.) led to displacement crossing with HF cattle in the western federal states (= German Holstein cattle, DH), a crossing that was also largely practiced in eastern Germany after reunification. From the once widespread "old" German Black and White cattle (DSN) only small numbers of cattle still exist. Since the early 1970s this endangered breed worth protecting is kept alive today in the form of genetic reserves. Preservation of the breed is supported by state subsidies. DSN breeding targets have seen a number of changes and have thus undergone specific adjustments to economic developments and consumer requirements. Currently, the additional, consistent inclusion of health criteria is of great interest. Fixing objectives for the breeding of Deutsche Holstein will most likely become more complex given the fact that environmental aspects and the protection of resources will need to be taken into account more fully. DH breeding will certainly remain an exciting business. Source

A comprehensive crossbreeding experiment with North American Jersey bulls and Holstein cows was initiated in Saxony and information of these animals is meanwhile available. Data of crossbred offspring of twelve North American Jersey bulls and their respective herd mates were used for analysing fertility, calving and production traits. With increasing production level of the herds (average milk yield of purebred Holsteins) the inferiority of the F1 animals increased in milk yield. An interaction between herd milk production level and breed could be observed. F1 cows were considerably better than the purebred Holsteins with respect to maternal calving traits. © Verlag Eugen Ulmer, Stuttgart. Source

In Germany, performance of dairy cows has grown rapidly particularly in recent years due to successful selection for higher milk yield with improved feeding, husbandry and veterinary care. Mean performance of more than 11,000 kg of milk/cow/year are no longer a rarity on herd basis. Correct evaluation of feed intake (FA) requires a differentiated evaluation of this trait in lactation. FA is genetically determined differently in different periods of lactation and also genetic relations to milk yield are variable. FA reacts indirectly to one-sided selection for higher milk yield. Model calculations on the basis of the modern theory of artificial selection, however, show that with one-sided selection for high milk production, especially during first lactation, energy balance (EB) of dairy cows continue to deteriorate. Avodiance of further adverse development of negative energy balance (NEB), both in terms of extent and duration during first lactation, requires a positive evaluation of feed intake in the selection process while taking into account other traits (e. g. body mass) within the first third of lactation. During the second and third trimester of lactation, during which cows are commonly found in a balanced energy status, evaluation of FA is significantly differentcompared to the first trimester of lactation. Because in future animal health and animal welfare as well as bioethics of production of foods of animal origin are becoming increasingly important with regard to the acceptance of modern animal husbandry in public, inclusion of feed intake in the breeding process of dairy cows are now increasingliy considered in order to avoid a further increase in NEB.

Beef production with suckler cow herds is linked with considerable emissions of greenhouse gases and air pollutants. In order to identify reduction potentials under Germanmarginal conditions, the entire production process including suckler cows and their offspring has to be reflected in a model. The work at hand describes the calculation procedures involved. It excludes feed production. A first step compares two suckler cow herds with equal populations but different genotypes (German Angus and German Beef Simmentals) with their typical different weights and weight gains; all other variables (feed quality, housing and manure management) were kept constant. Our calculations confirm the comparatively high emissions per unit of product. However, the difference caused by genotypes is negligible, if one chooses identical fattening periods (here 300 days). The lesser emissions per animal found for the Angus herd were counterbalanced by increased amounts of usable products from the Simmental herd. © Verlag Eugen Ulmer, Stuttgart. Source
