Dry cow and heifer feeding program for the University of Manitoba dairy herd

Source: Manitoba Agriculture Food, and Rural Initiatives The feeding programs for dry cows and heifers seldom receive the amount of attention given to rations for the milking herd. Yet anyone who has had problems with milk fever, displaced abomasums and other metabolic diseases as well as poor heifer production, knows how important proper feeding of these

New barley survey powers strategies to harvest more feed value

Source: Canadian Bio-Systems New data and analysis from a survey of barley samples from across Alberta will help Canadian livestock producers and industry get more bang per bite from this important feed ingredient. The survey was led by Canadian Bio-Systems Inc. (CBS Inc.) and the University of Manitoba, with sample collection assistance from the Alberta

Ideas for coping with heavy corn silage feeding

Source: Ontario Ministry of Agriculture, Food and Rural Affairs Check particle size of corn silage to ensure adequate effective fiber When corn silage is the major forage, 5 to 10% of particles should be greater than 0.75 inches; for rolled or processed silage, 10 to 15% of particles should exceed 0.75 inches Feed more protein

Pricing Home-Grown Forages

Source: Manitoba Agriculture Food, and Rural Initiatives One of the biggest problems when calculating feed costs is assigning an accurate value to home-grown forages. Most areas have an established dry hay market and it is relatively easy to estimate a hay price based on the market value of comparable quality hays. It is much more difficult

U of Illinois researchers find better ways to predict energy value in feed ingredients

Source: University of Illinois news release To formulate cost-effective livestock diets based on energy, it’s vital that the energy content of feed ingredients is known as accurately as possible. Researchers at the University of Illinois are working on more accurate ways to predict the energy value of ingredients. Hans Stein, professor in the Department of

Feed sorting in dairy cattle: Causes, consequences, and management

Source: Journal of Dairy Science E.K. Miller-Cushon, T.J. DeVries ABSTRACT Dairy cattle commonly sort total mixed rations, a behavior that influences individual nutrient intake and reduces the nutritive value of the ration left in the bunk across the day. Typical patterns of feed sorting in lactating dairy cows, against longer forage particles, result in greater intake of

Feeding Dry Cows A Single TMR Could Be Enough

Source: Ontario Ministry of Agriculture, Food and Rural Affairs Pennsylvania State University researchers have been examining the traditional approach of feeding dry cows in two separate groups. Their findings suggest that if a two-group approach isn’t working on your farm, feeding dry cows a single total mixed ration (TMR) could be beneficial. Dry cows are

Hubbard Feeds: why high-quality water matters

Source: Hubbard Feeds news release Often overlooked, water is the most important nutrient for dairy calves. It is required for all of life’s processes including the transport, digestion, and metabolism of nutrients, the elimination of waste materials and excess heat from the body, and the maintenance of a proper fluid-ion balance in the body.

Effect of grain source on the requirements of dairy cows for physically effective fibre

Source: Agriculture and Agri-Food Canada Wen Yang and Karen Beauchemin • Agriculture and Agri-Food Canada Research Center, Lethbridge, Alberta Take home message The physical effectiveness factor (pef) is determined as the proportion of the TMR (as-fed) retained on the 0.75” and 0.31” screens of the Penn State Particle Separator. The peNDF is determined by multiplying
