TL;DR: Semen that was diluted and stored in the commercially available Tris-based extender (T2) maintained sperm motility for a longer period of time, and acrosome and membrane integrity was higher during storage for up to 30 h as compared to the other extenders independent of storage temperature.

TL;DR: Motility and acrosome integrity were assessed after storage at 16–18°C for 6, 30, 54, 78, and 102 h and there was a significant influence of boar and sperm concentration on motility, while acrosomes integrity was affected only by boar.

TL;DR: Mulberry III and X-cell preserve sperm quality, as well as that of BTS on Day 3, for up to 5 days after collection, which is preferable from a production and economic point of view.

TL;DR: Liquid ram semen diluted in a milk-based extender and vaginally inseminated once in natural heat, with a semen dose of 150 x 10(6) spermatozoa, gave acceptable fertility results and is to be recommended as the method of choice in Norway.

TL;DR: The superior fertility results achieved for minitubes compared to mini straws have to be carefully evaluated in relation to the possible application of a more rational semen production and simplified semen handling at AI, when usingmini straws thawed at 35 degrees C.
