Dairy Corner: Not only disease, but even heat stress can quickly take its toll
It might be a scouring sick dairy calf or an otherwise healthy one suffering from stress, but death can be minutes away if either calf loses more than 10 per cent of its bodyweight in fluids (water and electrolytes). Fortunately, we can save many of these dairy calves by recognizing the symptoms of dehydration and […] Read more
Although the price has shot up, it is important to keep the nutrient in dairy rations
Prices of vitamin A (along with vitamins D and E) have increased to 10 times their former costs from just a few months ago. This skyrocketing price is due to a recent fire at a new manufacturing facility in Germany as well as several vitamin ADE plants that are down for maintenance in China. Together, these events have caused a worldwide shortage […] Read more
These single-cell organisms can hit on many cylinders to help optimize milk performance
For many years, I have formulated dairy diets with yeast for both dry and lactating dairy cows. It has been my professional intention to promote good dairy nutrition, or solve a particular problem that limits good dairy performance. On occasion, I have seen direct benefits within a couple of days by adding yeast, while other […] Read more
Ration should be about 80 per cent of the lactation nutrient package
As a dairy nutritionist I’ve noticed a new trend among dairy farmers in the last few years in feeding and management of their dry cows. The line between a faraway dry cow and close-up dry cow has faded and producers are feeding much more nutrient-packed rations to them than we used to. I am not […] Read more
Incidence of the calcium deficiency can be sporadic, but hurt when they hit
Clinical milk fever is a particular insidious metabolic disease in freshened dairy cows. I have witnessed on some dairies, it’s not a significant problem, while next-door neighbours are plagued with downer cows one calving after another. In other dairies, milk fever doesn’t show up for months and then it shows up with a vengeance. From […] Read more
Look to find a balance between very expensive and very cheap rations
Occasionally, I talk to dairy producers about the financial aspects of operating a barn, aside from dairy nutrition. All producers wish to reduce their lactating feed costs. One producer I know wants to switch to a notorious cheap protein supplement, while another wants to hire a private dairy consultant and tender out all dairy feed […] Read more
It takes time for a calf stomach to develop to handle certain feeds
I visit literarily hundreds of dairy farms across Canada each year. On most, pre-weaned dairy calves are raised away from the main lactation barn or older replacement heifer facilities. Whether these baby calves are housed in hutches, group pens or brand-new calf barns, when I find a group of calves that are sick and not […] Read more
Assess what’s happening at the feed bunk, supply proper ration
There is only one way I know to supply the essential nutrients to high-producing cows to yield large volumes of milk, milk-fat, milk-protein and solids — assure dairy cows optimize dry matter intake of good feed is at its best. As a dairy nutritionist, I am so convinced each bite of lactation diet counts that […] Read more
Dairy Corner: Satisfying thirst also promotes good dry calf starter intake
Feeding milk replacer or whole milk does not provide enough water for growing pre-weaned dairy calves. Young calves have a natural requirement for water which is often higher and separate than what is provided by most milk-based feeding programs. By providing all the water needed, calves adapt to dry calf starter quicker, grow faster and […] Read more
Palm fat can help increase milk fat, but more isn’t necessarily better
There has been an explosive use of palm fat in many dairy diets. This growth has been fuelled by the numerous incentive days issued by milk marketing boards to increase milk fat production in lactating dairy cows. On the plus side, I see a profitable milk fat increase on many farms because some bypass palm […] Read more
