This is a very productive herd selected and managed to keep the average mature size around 1200 pounds. The average weight of the cows and weaning weight of the calves are 1210 pounds and 609 pounds, respectively.irst it has impacted our production costs. Heavier cows have higher nutrient requirements that must be satisfied for them to remain productive. It has been estimated that for each 100-pound increase in mature weight a cow requires an additional $15 - $20 in supplementation costs.
