fertility
first? is the result of a study made by vikinggenetics in
australia
. the main goal of the tool is to get the highest possible amount of
cows
pregnant fitting perfect to seasonal calving, which is more com- mon in england, ireland,
australia
and new zealand. according to the incalf
fertility
data project 2011, the results for sev- eral
fertility
traits have declined over the last ten years in
australia
. how to succeed when you don?t have too much time and the
fertility
rate is dropping? the answer is a tailor made solution called ?
fertility

n conditions and needs. the scandinavian strategy was implemented as a pilot-project in north east victoria. the most com- mon way in
australia
is not to pre- check the
cows
before starting the ai. the project involved 2,500
cows
in 10 herds, with a herd size ranging from 110 to 500
cows
. johansson classified the
cows
in five categories: cystic

fertility
first? project consists of a pre-check before artificial insemination (ai) to guarantee that the selected
