Use of immobilized cryopreserved bovine semen in a blind artificial insemination trial
Fride Berg Standerholen, Karin Elisabeth Waterhouse, Anne Guro Larsgard, Randi Therese Garmo, Frøydis Deinboll Myromslien, Jan Sunde, Erik Ropstad, Geir Klinkenberg, Elisabeth Kommisrud, To make timing of artificial insemination (AI) relative to ovulation less critical, methods for prolonging shelf life of spermatozoa in vivo after AI have been attempted to be developed. Encapsulation of sperm cells is a...

New semen processing technologies – no need for optimal insemination timing?
IC Oskam1, KE Waterhouse1, AH Alm-Kristiansen1, IS Grevle1, J Sunde1, RT Garmo1, G Klinkenberg2 1Biokapital AS, Hamar, Norway; 2Sintef, Norway Enhancement in cattle production is the result of implementation of new biotechnological techniques and production practices. However, many studies report a decline in the fertility of dairy cattle. The causality for this decline is multifactorial and costs to control fertility...

SpermVital® - is exact timing of insemination not important any more?
E Kommisrud1,2 1Hedmark University College, Hamar, Norway 2SpermVital AS, Hamar, Norway To make artificial insemination (AI) an even more valuable breeding method an immobilization technique for spermatozoa has been developed. The technology has successfully been combined with cryopreservation, a necessity for AI in cattle. The idea of immobilizing sperm cells arised to improve fertility results and make AI more flexible...
