Abstract

The objective of this field trial was to compare the odds of pregnancy at 25 days (P25) and at 60 days (P60), of embryonic death (ED) between 25 and 60 days, and of non-pregnant cows returning to heat 20-25 days after artificial insemination (AI). Three fixed-time insemination protocols involving...

Abstract

In a 2-year study, run as part of the artificial insemination programme in Thessaloniki, Greece, milk progesterone and oestrone sulphate concentrations were used to monitor and assess pregnancy in lactating Holstein cows. Milk samples were taken on the day of insemination (day 0), day 21, day 42...
