Abstract
SUMMARY: The effects of supplementary feeding of licks containing non-protein nitrogen on the reproductive performance of beef breeding cows and on the live-weight gain of growing stock in Botswana is described. The trials involved 1375 breeding cows at five artificial insemination centres, and 360 breeding cows and 269 growing stock under ranch conditions. These licks increased the percentage of pregnancies in cows under lactation stress by up to 20%, but had no effect on the reproductive performance of dry cows or cows with a calf older than 5 mo. In growing animals the provision of rumen stimulatory licks increased live-weight gain by an average of 12%, but was of doubtful economic value.This publication has 1 reference indexed in Scilit:
