Livestock nutritionists will tell you that those last few weeks before calving are the most critical time for the nutrition for your cowherd, writes Clint Peck. Diets for gestating heifers and cows must support lactation, fetal growth and replenishment of body condition at varying times during pregnancy. Grazing alone will often not meet the requirements of pregnant cows for the duration of pregnancy.
Peck says BCS and lower critical temperature are important considerations for the third trimester and maintaining overall herd health.
