Milk Urea Nitrogen (MUN)
Milk processing plants and DHI can provide dairy managers with milk urea nitrogen (MUN) values on bulk milk and individual cow milk samples. MUN tests are useful tools that can allow the dairy managers to monitor changes in the feeding and management of their herd. Milk urea nitrogen is the fraction of milk protein that is derived from blood urea nitrogen (BUN). In Holstein’s MUN normally represents about 0.19 percentage points of the normal 3.2% total milk protein.
Heifers are the future of your herd and your long-term success as a dairy producer. Heifer raising makes up 20-25% of the total cost of milk production. A successful pre-weaning calf program has been proven to increase first lactation milk yield by 1,000 lbs – 3,000 lbs. Genetic selection can account for 150 lbs-300 lbs greater milk production per lactation, but pre-weaning management can increase this 5-fold.
The best way to prevent cattle from catching illnesses and diseases is cleanliness. Keeping cattle clean starts with their bedding. Nice, dry, clean bedding prevents the cattle’s coat from being covered in manure and mud. Many benefits come from clean, dry bedding as the insulation properties of the cattle’s hair coats are enhanced due to them being clean and maintained. In cold weather, a clean cow coat helps cattle use less energy to stay warm, and more energy goes into immune function growth.
Milk Fever
Milk fever, also known as hypocalcemia is a common bovine metabolic disorder resulting from calcium deficiency. Cows usually experience milk fever when approaching calving or just after calving. Calcium demand for a cow starting lactation is almost double compared to when she was not lactating and pregnant. Around calving, blood-calcium levels may drop below the normal range leading to homeostatic failure.
Calcium deficiency results in:
Mastitus
Summer heat and humidity can create the ideal environment for mastitis-causing pathogens to grow. In addition, intense heat can cause the cow to become stressed which results in lowering the immune system function. These two factors together create the perfect storm for mastitis to take a toll on the herd.
Bovine mastitis is the most costly disease for dairy producers. Mastitis is an inflammation of the mammary gland that is usually caused by bacteria that enter the gland through the teat end.
To make improvements to dairy farm margins in challenging times, dairies should look “lower” to increase profitability — all the way down to the ground, according to Midwestern BioAg’s nutritionist.
“If you grow your own forages,” says the BioAg nutritionist, “we can help you improve profitability by building a fertility plan to grow a better quality, higher-yielding crop. There’s a lot of revenue potential in the soil, and we can help you unlock it.”
By taking a systems approach to dairy farm management, Midwestern BioAg consultants …
