The Cattleman magazine is received monthly by TSCRA members as part of their membership in the organization.
The body condition score (BCS) of a cow prior to or at calving is the major factor affecting pregnancy rates. To optimize pregnancy rates, 2 and 3-year-old females should be in a BCS of 6 or better at calving.
Cows 4 years old or older should be in a BCS of 5 or greater. After calving, weight loss should be controlled so that cows don’t lose more than 1 body condition score in about a 100-day period.
If hay or forage quality is low, appropriate supplementation to achieve or maintain these targets will ensure that low BCS does not reduce pregnancy rates.
