This is a mixture of semen from three British Blues, designed to have higher fertility than an individual bull, due to variations in the rate at which the different bulls' semen becomes capable of fertilising the egg in the cow.
The bulls in BLUE POWER EXTRA are selected for calving ease, with shorter gestation periods ranging from 279 to 282 days.
All the bulls are white in colour, producing very marketable blue-roan calves from Holstein cows.
