Résumé anglais |
In the Departement of the Loire, 70 % of the bovine live-stock — overwhelmingly dairy-breeds — are insiminated artificially. In the North of the Departement, artificial insimination is seldom resorted to in breeding Charolais beef-cattle. Until 1984, industrial crossbreeding with Charolais cattle semens-representing over half the total insiminations — had lost to rising insiminations of pure dairy-breeds. The first effects of the policy of dairy production control can be found in the 1984 results showing a fall in insiminations on dairy-breeds and a rise in industrial cross-breeding. Increasing use of new techniques such as embryo transplant, will go a long way to preserving the genetic quality of livestock. Source : Éditeur (via Persée) |
