- High corn prices make feeding dairy herd a challenge
- Lower quality feed
• Couple high corn prices with a shortage of quality alfalfa hay, and it’s understandable that dairy farmers are feeling the pinch trying to feed their herds.
• Dairy cows need a consistent ration in nutrient composition on a regular basis. It takes the cow’s rumen bacteria at least two weeks to adjust to changes and the fewer the changes, the better.
Lower quality feed
“When farmers harvest corn that is too dry, it doesn’t pack as well in the silo, doesn’t ferment correctly and it results in lower quality feed for the dairy herd,” Amaral-Phillips said.
“Another thing farmers may forget is that improperly covered silages result in excessive losses in the storage structure. These losses are not seen unless the differences between the amounts of silage entering and fed are measured.”
She said farmers need to pack bunkers and piles, especially the top 6 inches of silage, and then cover them with plastic and then tires that touch one another. It’s a good idea to level off and cover uprights. With bags of silage, it is important to prevent birds and rodents from damaging the bags.
“Corn silage is valued at seven to eight times the price of corn grain, plus an additional $10 for harvest and storage,” Amaral-Phillips said. “So, at $7-corn, each ton of corn silage is worth $59 to $66. Corn silage is a very valuable crop this year — taking time to properly cover it will save you feed dollars.”
With current prices, energy is actually the most costly nutrient for farmers to provide their herds — not protein. Energy can cost more than 2.5 times as much as protein in dairy rations.
Amaral-Phillips suggested that dairy farmers work closely with a nutritionist to make the most of their feed dollars. Forage testing can be a big help in balancing diets for milking cows and dry cows and heifers.
Amaral-Phillips offered a few key points to remember when talking with a nutritionist.
“First, dairy cows need nutrients, not ingredients,” she said.
“Nutritionists can use ingredients other than corn grain to provide some or most of the starch in a dairy cow’s diet. This approach allows you to balance rations for least cost but, at the same time, provide the rumen bacteria, and the cow herself, with what she needs.”
She said balanced rations contain certain amounts of dry matter provided by various ingredients. As the dry matter or moisture content of wet feeds changes, the farmer needs to accordingly change the amount they feed or add to the mixer.
Dairy cows need a consistent ration in nutrient composition on a regular basis. It takes the cow’s rumen bacteria at least two weeks to adjust to changes and the fewer the changes, the better, Amaral-Phillips said.
“We can economically feed the dairy herd, even with high corn prices,” she said. “We just have to pay attention to some of the finer points in our feeding and management programs.”
