Strategies of European Fleckvieh Cattle Breeding to Optimize Dual-purpose Breeding Particularly for Beef Production
نویسندگان
چکیده
The Fleckvieh breed, while internationally recognized as a dual-purpose breed is primarily used as a beef production animal in Ireland. However because of ever increasing pressure to improve efficiency, it is now accepted in Irish cattle breeding that beef production characteristics should be included in the national dairy cattle breeding programme. This development was accepted following a comprehensive review of the national cattle breeding programme. This review was initiated by the Irish Cattle Breeding Federation (ICBF) which was established in 2000 to organize and coordinate all cattle breeding functions. These breeding functions were conducted by the Irish Department of Agriculture up until that time. ICBF is owned by the main organisations which make up the cattle breeding industry. These are: Commercial and Pedigree Farmers Breed associations Milk recording organizations and Artificial Insemination bodies The federation is funded by Government grant, a proportion of ear tag sales revenue and fees for services provided. Its mission is to ‘achieve the greatest possible genetic improvement in the national cattle herd for the benefit of Irish farmers, and the Dairy and Beef industry and members’. Since its creation, ICBF has undertaken a major review of the organization of all cattle breeding functions in Ireland. Research was initiated immediately in three main areas. These were, genetic evaluation, data management and breeding scheme design. Some of the material described in this paper resulted from this review, which is

Artificial insemination is a well-established and widely used method for genetic improvement in cattle breeding industry. Recently, researchers have shown an increased interest in the cryoprotective effects of minerals and antioxidants on semen. Previous studies on calcium (Ca) and magnesium (Mg), two main macro-minerals, have mainly investigated their roles in mammalian spermatogenesis and fer...

Intensive milk and beef production is COIlIIlPn to the European agricultural due to a high density of population. Milk and beef traits are involved in breeding objectives of dual-purpose cattle. Various dual-purpose cattle populations cover a wide range of economic ting of milk and beef.

متن کاملMilk and Beef Production in Temperate Climates
Milk production in the temperate climates accounts for 66% of the world milk output. In North America only about 20% of beef originates from dairy herds, while in Europe beef production is a by-product of dairying. Several studies showed small genetic correlations between milk and beef traits, thus suggesting the possibility of simultaneous selection for both .characteristics. European breeding...

INTRODUCTION Beef breeding programmes have developed significantly in the last 24 years since the 1 WCGALP. Breeding programs as defined here include the definition of breeding objectives, recording and genetic evaluation programs to develop selection criteria and developments in selection and mating technology to optimize genetic progress for the objective. Available today are tools for the im...

The purpose of this essay is to develop a historic perspective of the beef cattle population and the legion of people directing its genetic change so that future leadership can increase the rate of breeding technology assimilation. Use of cattle for beef to feed millions is relatively recent. The beef industry of the United States has a rich, romantic heritage that combined Spanish exploitation...
