Abstract

The study was conducted on 15 Frieswal and 8 Sahiwal anoestrus heifers having mean age of 27.5 and 27.4 months,
respectively. These animals were administered vitamin-A @ 6 lac IU per week for 2 weeks and Tonophosphan @ 2g/heifer for 5
alternate days. Eighty percent heifers in Frieswal and 66.6% heifers in Sahiwal exhibited oestrus after 10.25 and 21.00 days of
treatment, respectively. Analysis of data revealed that treatment had a significant (p<0.01) effect on resumption of oestrus, which
was ovulatory in Frieswal and Sahiwal heifers.
