Objectives
To evaluate the oestrous response and pregnancy rate following timed artificial insemination (TAI).

Nguni ≤2.5 20 100 45
Nguni ≥3 50 100 60
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.
