corn silage chopping

Right and wrong fermentation

Dairy Corner: If silage moisture is too high going in, it can affect feed quality and palatability

This autumn, I have seen a variety of corn fields being chopped into silage for dairy cattle. While some of this corn was dried enough to make some good quality corn silage, I was surprised when I saw some producers literarily harvested green chop. After all, they were faced with another rain shower, which forced […] Read more

Dairy Corner: Twofold impact of heat stress

Reproduction setbacks may take longer to correct than milk production problems

This summer in the eastern Prairies seemed to be hotter and definitely more humid than in previous years. I noticed this year in particular had many August nights when the humidex barely fell below 25 C. In talking to dairy producers, some had the same experience and also noticed their heat-stressed cows’ milk production as […] Read more

Proper diet reduces risk of lame cows

A well-balanced ration and a clean barn are a great combination to keep dairy cows mobile

There are three stages to the corn harvest in Manitoba. The first starts in September when the corn crop matures and whole plant moisture dries to about 35 per cent dry matter — it’s one of the best time to take off corn silage. The second occurs weeks later when the grain corn dries to […] Read more

Mud is a hotbed of disease and poor eating habits for dairy cattle

As little as four inches of mud can slow performance and it can 
be an excellent environment for disease affecting cattle health


Once I was checking the spring ration for a dairy producer who raised a group of replacement dairy heifers in a drylot. The mud was about a half metre deep and with each step toward the feeder, it was slow going. About half-way along, my boot got stuck and by struggling, I buried it. Abandoning […] Read more
