Engineers and scientists from Inra and the Institut de l’Elevage (the French livestock Institute) are also invited to the CNBL.

and Firmiaty, S INSEM Ovin vous accompagne tout au long des étapes indispensables à la bonne réussite de l’insémination animale. Uterine horn insemination give a modest improvement in conceptions rates particularly in situations where conception rates are low following uterine body inseminations. Indépendantes lors des mise-bas, leur croissance est plus lente ce qui se traduit par une viande de qualité supérieure.

Profiter de la meilleure génétique pour un élevage performant et rémunérateur :

From the beginnings of breeding schemes, people working in the selection of dairy sheep breeds implemented an overall service adapted to the specifics of this production: mountain areas, seasonality, large flocks, rapid milking units, specific recording tools, use of fresh semen for animal insemination. Yuan, Zehu Insémination : Si les brebis sont en extérieur, les rentrer au moins deux heures avant l’insémination, Respecter scrupuleusement l’heure d’insémination prévue, Garder les femelles 2 à 3 heures au calme à l’intérieur après l’insémination, Pour assurer une repasse, introduire les béliers six heures après l’insémination.

Simplification du travail There is emerging evidence that having one insemination time, when all cows requiring insemination in the herd on that day are inseminated, does not compromise fertility provided insemination technique is good and the semen used is of high fertility.

CNBL is a member of France Génétique Elevage (FGE), and within the sheep commission of FGE, CNBL is the place for dialogue and exchange for genetic improvement of dairy sheep breeds. The Institut de l’Elevage is also in charge of technical administration and promotion, Cart L’Insémination Artificielle est la technique de PMA la plus simple à réaliser.

and The latter has been greatly facilitated by the ability to successfully cryopreserve semen. Les brebis entre 10 mois et 3 ans.

37 technical and genetic actors associated. The dairy ewes national committee (Comité National Brebis Laitieres, CNBL) federates the 37 technical and genetic organisations present in the industry. De plus, les élevages sont inscrits au CSO tremblante. The objective of an insemination is to ensure that there is an adequate reservoir of competent, capacitated, motile sperm in the caudal region of the oviductal isthmus, the site of the main sperm reservoir in the cow, at the time of ovulation to ensure fertilisation. 11 Allée du Breuil 87430 Verneuil-sur-Vienne, Tel : 05 55 00 14 62 Mail : contact@insemovin.com, Accueil / Taponen, J. The short insemination times rarely occur since they require the ideal conditions for insemination (immobile ewe, accessibility of the cervix, etc.).
