Livestock straight-breeding system structures for the sustainable intensification of extensive grazing systems
نویسنده
چکیده
ICAR Technical Series No 3 Animal breeding aims for genetic improvement of livestock by utilising the genetic variation available, both within breeds and between breeds. The animal genetic variation can be used to accommodate interests and farmers’ wishes to make livestock more efficient in using available resources to produce human food and other agricultural products. In general, improved performance leads to more animal products for the same amount of input resources. As selection and breeding of animals is a gradual process, it is more likely that the main stakeholders in the production system are able to adapt to the intended changes. Moreover, genetic change is permanent and the improved production system does not necessarily require a continuous use of more expensive or more sophisticated input factors. Gradual genetic improvement is the most sustainable form of improvement of the efficiency of a production system.
