Effects of milk replacer program on nutrient intake, growth

The aims of this study were to determine if feeding frequency (FF) of milk replacer (MR; meals/d) alters starter intake, growth and efficiency of growth in nursery calves fed a conventional or accelerated MR. FULL STORY »

Consistency in rations can help reduce competition at feed bunk

We are learning more about the feeding behavior of dairy animals housed indoors. FULL STORY »

Brown midrib corn silage can result in longer peak milk yield

We’ve all heard the benefits of brown midrib (BMR) corn silage, owing to higher digestibility. FULL STORY »

Effects of feeding brown midrib corn silage with alfalfa hay

This experiment was conducted to test a hypothesis that lactating dairy cows fed 35 percent brown midrib corn silage and 25 percent alfalfa hay would consume more DM around peak lactation compared with those fed conventional corn silage, resulting in longer peak milk production. FULL STORY »

Sampling behavior of dairy cattle

Factors affecting sampling behavior of cattle are poorly understood. The objectives of this study were to measure the effects of variation in feed quality on the feeding behavior of Holstein dairy heifers. FULL STORY »

Subpopulations targeted for oral calcium supplementation

Lame cows and high-producing cows are good candidates for oral calcium bolus supplementation. That’s the word from scientists at the University of Wisconsin-Madison and Boehringer Ingelheim Vetmedica. FULL STORY »

Advice for setting MUN targets

People pretty well agree that an “acceptable” milk urea nitrogen level is in the 11 to 15 range. But there can be variation between herds and within herds. FULL STORY »

More research needed on CLA-fortified milk

There have been discussions over the years whether the diets of cows can be enhanced to encourage production of conjugated linoleic acid, which has health benefits for consumers. FULL STORY »

Effect of linoleic acid and dietary vitamin E supplementation

Conjugated linoleic acid, a bioactive fatty acid (FA) found in milk and dairy products, has potential human health benefits due to its anticarcinogenic and antiatherogenic properties. FULL STORY »

Oral calcium bolus supplementation on early-lactation health

The objective of this study was to evaluate the effect of supplementation with oral Ca boluses after calving on early-lactation health and milk yield. FULL STORY »

Cow and herd variation in milk urea nitrogen concentrations

Milk urea nitrogen (MUN) is correlated with N balance, N intake, and dietary N content, and thus is a good indicator of proper feeding management with respect to protein. FULL STORY »
