There is no question that heat stress can negatively impact animal performance. Exposure to heat stress reduces daily gains, milk production, and reproductive efficiency, though specific impacts on production varies depending on the magnitude and duration of heat exposure. Prolonged exposure to heat stress is much more detrimental than short-term heat stress and its effects linger long after temperatures drop back below the heat stress threshold.

Winter cover crops can be a good forage source for dairy cattle. Harvesting in the early boot stage will generate a quality forage that can be incorporated into the lactating cow diet. Here we will compare the nutrient profile for various silages produced from winter annuals with the more traditional corn and alfalfa silages.

How many animals will my pasture support? This is a common question, especially for the first-time livestock producer. Unfortunately, it is a complex and often difficult question to be answered.

Topics include the cost of production, heifer benchmarks, fly control, and pasture management.

While it has been demonstrated that feeding hay is not needed to support adequate rumen development before weaning, there are some occasions when feeding a small amount of forage before weaning can be beneficial.

Summer is here and with that comes, what sometimes seems, a never-ending battle with flies. Flies can pose a significant problem for all animals on the farm. Following a (usually much welcomed) bout of wet summer weather, fly populations sometimes seem to explode. There are three major types of flies with economic significance to the U.S. dairy industry: horn flies, face flies, and stable flies. Control measures vary somewhat depending on which type of fly is causing issues. Below are four steps you can take to help reduce the fly load for your animals.

What price are you getting per cwt of milk? Like most dairy farmers, you know the price or you can get it quickly by reviewing milk check receipts. How much does it cost you to produce a cwt of milk? Like many dairy farmers, you may not know. Dairy farming is complex, and determining your costs of production is sometimes difficult. Yet, your costs directly affect your profit, and it is important to understand them.

Heat stress can have dramatic and lasting impacts on the performance of dairy cows, heifers, and calves.
