Cattle prefer to pick up dropped ears of corn, husks, and leaves and will not eat the stalks unless forced to.
There is about 16 pounds of dry matter of leaves and husks for each bushel of grain produced.
For example, a pregnant dry 1200 pound cow only requires 8-10 pounds of total digestible nutrients (TDN) per day during mid-gestation, whereas that same cow requires 14-16 pounds of TDN during lactation.
This does not account for the needs of the calf who will begin grazing within the first month of life.
The cows lost a little over half a body condition score but had acceptable breeding rates.
The calves gained just under 2 pounds per day in this study conducted from November to April (https://edu/7do2).
Cow-calf producers know that reproduction is the most economically important trait and this meeting brings together some of the most practical and knowledgeable individuals in the industry to discuss reproductive management.
The Beef Reproduction Task Force, which includes reproductive physiologists from land-grant universities work together on reproductive management education.
However, subsequent birth weight and pregnancy rates were similar suggesting the added cost of protein supplement to the spring calving cow over the winter when residue was adequate for grazing was not beneficial https://edu/4f986585-d3f1-4e00-ad3b-9945992c0af7
Late summer or fall calving cows grazing cornstalk residue with their nursing calves have a much higher nutrient requirement than their dry counterparts.
The program is a joint effort of the Task Force and K-State Research and Extension.
