Winter feed will be a scarce and costly resource in much of Western Canada this year. Use it carefully, because the management decisions you make now will impact reproductive and economic performance for at least two years.
Research conducted 25 years ago by P.L. Houghton and co-workers at Perdue University (J. An. Sci. 68:1438) demonstrated how energy intake by pregnant and lactating cows impacted their reproductive and calf performance. At the start of the last trimester (early January for cows calving in April), cows were fed in two groups. One group received a maintenance diet (ME) meeting recommended energy intake. The other was fed a low energy diet (LE) providing 70% of recommended energy intake. After calving, each group was split again, with cows receiving either the low energy diet or a high energy diet (HE; 130% of recommended energy intake). Skimping on nutrition in late pregnancy and after calving impacted both Continue reading →
Feed testing is a fundamental tool to assist cow-calf producers, backgrounding operations and feedlots develop sound feeding programs. By knowing the nutritional qualities of feeds, producers are better able to achieve desired production targets and save on supplemental feed costs. Feed testing is especially important to accurately determine the feed quality of forages, because visual appraisal of colour, plant species and leaf content, and knowledge of cutting time, can be misleading and should not be relied upon to determine feed quality.

Alternative feeds can help reduce feed costs or stretch feed supplies, but it’s important to take the time to understand the nutritional quality of the feeds that are available, and become aware of any potential health risks to your cattle by including them in feed rations.
A producer from South-Central Manitoba who has had to pull his cows off dry pasture early recently asked us about feeding soybean straw and kochia. Continue reading →
