Lot one (n = 10) was inseminated in September by artificial insemination of the farm. Lot two (n = 10) was inseminated by the same artificial insemination in October, and three in the batch were inseminated by a nine animals inseminator experienced in November. The pregnancy rates were 10% (1 / 10) 20% (2 / 10) and 77.77% (7 / 9) respectively for lots one, two and three, and can confirm how much manpower trained is important for obtaining good results in reproductive programs.
