We calved out 85 heifers in 2015 and only pulled one calf which had died in utero a few days before she went into labor, thus not initiating a normal parturition.

* In 2012 Because of the drought, the first calf heifers' calves were weaned at 60 days of age; The rest of the calves were weaned at 90 days of age
For the last two years, the heifers have been developed on corns stalks with one pound of distillers grain per head per day. These yearling weights are taken before they are turned out onto annual rye grass.

In 2014, we calved out 75 heifers and did not pull a single calf
In the mature cows, we had two calves with malpostions Those were all we pulled.

Calving Ability Scoring System
1 = Normal birth, no assistance
2 = Easy pull
3 = Hard pull
4 = Cesarean
5 = Mal position

As you can see, we do not assist very many cows. We calved out 101 heifers in 2012 and assisted only 7 of them without losing a single calf.

Birth Weights
We estimate birth weights by using a calving tape. The tape correlates the diameter of the calf’s foot at the coronary band with birth weight. Since we are not selling bulls, we feel that this method gives us a good comparison within the herd and allows us to identify individuals that are too big.
