Control points in the preparation of semen doses: temperature control and quality parameters (1/2)
The impact of semen used for post-cervical AI is 2-3 times bigger than that used to produce cervical insemination doses; therefore, preparation of the doses should follow an even stricter control program.
44% less piglets under 1000 gram
In recent years, users of Topigs Norsvin genetics have experienced a clear drop in piglets with a birth weight below 1000 grams. Based on genotypic information, the percentage of piglets born with a weight below 1000 grams dropped by 44% between 2012 and 2016.
