Abstract

The pregnant Karan-Fries (KF) cattle were either fed basal ration only (0Zn, n=6), or were daily supplemented
with 80 and 120 ppm Zinc (Zn), respectively (80Zn or 120Zn, n=6 each) for 45 days before and after calving to
assess their producing ability, parity and body weight. The number of cattle exhibiting retained fetal membranes and
metritis were 2, 1 and 0 in 0Zn, 80Zn and 120Zn group, respectively. Moreover, compared to no Zn supplemented
group, in 120Zn and 80Zn supplemented group, there was reduction (p<0.05) in postpartum estrus interval, days
to first insemination, service period, services per conception and an increase in conception rate. In brief, the
supplementation of Zn improves reproductive efficiency of KF cattle.
