Modern livestock and aquaculture production aims for the production of healthy and robust animals with improved animal welfare and preserving genetic diversity. Animal breeding plays an important part in progressing animal production systems, from conventional to organics. By improving the abilities of animals for certain traits entire populations can be enhanced, creating benefits for farmers, consumers, and the environment.
Balanced breeding means to find a compromise between the health and welfare of animals, their environmental impacts and the quality and the quantity of the production (milk, meat and eggs). Currently, pigs and poultry only need half of the feed than 40 years ago. And improving robustness and longevity of dairy,, leg strength in both pigs and poultry, or reducing misbehaviour in pigs and osteoporosis in laying hens are some examples of breeding elements..
.Breeding is most successful in fall, when the length of the days decreases. Once the length of days has decreased, the ewes will enter heat every 16 or 17 days. Once the days begin to lengthen again, the sheep will enter heat less often and the breeding season will have passed
