Abstract

This research proves the effects of Calving Care on reproductive performance in dairy cow, during three successive lactations, on a group of 10 Holstein Friesian cows, using the method of period research. Group M1 / 2014 of 10 cows was considered the control group in which Calving Care was not administered, monitoring its reproductive performance throughout the lactation of 2014. Group E / 2015 was the experimental group, they got Calving Care 300 g / cow / day, 21 days before calving, homogenized in the TMR. The calculated cation-anion difference (DCAD) was -15.28 mEq / 100 g dry matter. Group M2 / 2016 was the second control group, without Calving Care, but the reproductive performance in the following lactation was monitored. After calving, each group was monitored for the service period length, calving interval, service per conception rate and voluntary waiting period. Calving interval has been reduced from 455,2 days in Group M1 / 2014 to 403,9 days in Group E / 2015 (± 3,497) and to 400,9 days in Group M2 / 2016 (± 4,750). Service per conception and voluntary waiting period had also significant differences between groups, suggesting that postpartum health is a direct factor in influencing reproductive performance.
