Dairy farmers urged to be on lookout for U.S. disease
Older, lactating cattle more likely to be severely impacted, effected farmers say
U.S. dairy producers are reporting high onset of and high morbidity from Texas Agalactiae Syndrome, with confirmed cases in Texas, Kansas and New Mexico. Lactating cows are considered particularly vulnerable.
Keep a full feed-bunk for optimum milk production
Availability of feed is important for maintaining cow body condition score
The common feed bunk in dairy barns should be managed to get a consistent daily intake of nutritious feed into lactating cows. This practice stabilizes feed’s rate of passage and its fermentation/digestion in the cow’s rumen and lower digestive tract. In turn, it ultimately meets the essential requirements of energy, protein, effective forage fibre, minerals […] Read more
Total US cattle herd drops to lowest level since 1951 – USDA
Easing dryness could encourage ranchers to begin rebuilding beef herds
Chicago | Reuters - The total number of U.S. cattle fell to its lowest level since 1951 as of Jan. 1, in the herd's fifth consecutive year of decline, U.S. Department of Agriculture data showed on Wednesday.
First-of-its-kind cattle methane limiter approved for Canada
Enteric methane emissions from cattle contributes 3.3 per cent of Canada’s total GHG emissions
A feed ingredient designed to reduce methane emissions in beef and dairy cattle has received market authorization in Canada.
There’s a reason if cows aren’t chewing their cud
It's important to look at the structure of fibre in the ration
This fall I visited three similar dairies milking between 100 and 150 cows. It was about 10 a.m. in two barns (different days) and midafternoon in the third. In each case I noticed less than 10 per cent of resting cows (three-quarters were lying down) were not chewing their cud. I reviewed the TMR in […] Read more
Canola meal makes milk on Canadian dairy farms
Dairy Corner: It’s readily available and priced better than some other proteins
If there is anything that defines a truly Canadian crop, it’s canola. Much of its intense breeding work started in the mid-60s by Drs. Downey and Stefansson. By the late 1970s, they successfully eliminated high levels of anti-nutritional components from rapeseed oil and turned it into a valuable food for humans. Likewise, canola meal, a […] Read more
Impact of heat stress in dairy cows can last for months
Dairy Corner: A few hot days in summer can have a significant impact on reproduction and milk production
Good research demonstrates that summer heat stress reduces the performance and health of lactating and dry dairy cows. The funny thing is most people forget that a good bout of heat stress during the summer can cause many problems that extend into the cooler autumn months. Therefore, we should be aware of the ways that […] Read more
Do you know your cattle?
Notes on Canada’s dairy and beef breeds
The cattle breeds I knew as a teenager are gradually disappearing. When it comes to milk breeds, we have essentially one type of cow, the black and white Holstein, which makes up 94 per cent of Canada’s dairy herds. Holstein is a misnomer in my thinking since in Wales we called them Dutch Friesians. I […] Read more
Balancing variable corn silage quality to a ration
Dairy Corner: Always recommended to start with a feed analysis to know what you have
I am amazed on how each summer differs in Manitoba. Two summers ago, we had severe drought, last summer was extremely wet and this year started with record heat, then cooled down to night-time single digits. Luckily, temperatures picked up again, all the while with spotty thunderstorms. Such climatic difference presents a patchwork of knee-to […] Read more
