Abstract

Five multiparous and four nulliparous cross-bred cows were administered s/c with oestradiol-$17{\beta}$ and progesterone 0.1 mg and 0.25 mg/kg. b.w./day for 7 days and 2 mg s/c twice daily of reserpine on days 9 to 12. Lactation was successfully induced in all animals for periods from 258 to 476 days. All animals were dried off for a minimum of 2 months. Subsequently, they were injected s/c with oestradiol valerate and hydroxyprogesterone caproate at 0.1 mg and 0.25 mg/kg. b.w./day on days 1 to 3 and 2 mg twice daily of reserpine on days 8 to 11. Lactation was successfully reinduced in all the cows for a period varying from 228 to 426 days.
