Conclusion• Village cows responded successfully to

oestrous synchronization programme regardless of geographic area and body condition.

• Cows with BCS of ≥3 had better pregnancy rate regardless of breed type and province. Moreover Nguni type cows performed better regardless of the BCS.

Implication of the study• Technology transfer

• Information dissemination.

• Livestock improvement.
