Reproductive performance of immobilized cryopreserved bovine semen used for timed artificial insemination.
Alm-Kristiansen AH1,2, Dalen G3,4, Klinkenberg G5, Bekk L2, Thorkildsen LT2, Waterhouse KE2, Kommisrud E1,2. The SpermVital® technology comprises embedding of spermatozoa within an alginate gel to facilitate release of sperm cells over a prolonged period in utero after AI. The aim of this study was to examine whether the survival time of spermatozoa is extended when applying this...

The 16th Annual Conference of the European Society for Domestic Animal Reproduction (ESDAR), 29 August-1 September 2012, Dublin, Ireland

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...
