Pregnancy or pregnancy examination (TU)
An animal is considered to be pregnant from an evaluable insemination if:
- no post-insemation (NB) took place and
- there is no negative pregnancy result and
- there is no departure due to infertility.
In central evaluations, the key figures for pregnancy are determined only from 90 days after the insinfusion in question.
When determining the non-return rate (NR90), the gestation study (pregnancy result) results are not taken into account.
In order to calculate the rates of pregnancy (TREB, TRG), the evaluable insamions must be determined.
