Extended prepartum feeding of negative-DCAD diets shows promise

A negative-DCAD diet fed for 21 or 42 days during the dry period can have positive effects on postpartum dry matter intake, calcium homeostasis and milk production, according to new research reported in the September edition of the Journal of Dairy Science. FULL STORY »

Study looks at higher-grain diets for young heifers

It’s customary to feed growing heifers high levels of forages and byproduct feeds because these feedstuffs provide an inexpensive source of energy and protein. However, growing heifers digest grains more efficiently than forages. FULL STORY »

Study on negative-DCAD diets

Low postpartum blood calcium remains one of the largest constraints to postpartum feed intake, milk yield and energy balance in transitioning dairy cows. FULL STORY »

Maximized feed intake ― access and consumption

Past research in dairy cattle nutritional management has focused almost exclusively on the nutritive aspects of the diet, resulting in many discoveries and improvements in dairy cow health and production. FULL STORY »

The motivation of dairy cows for access to pasture

Several factors influence whether dairy cattle prefer to be indoors or at pasture, including weather conditions and milk yield, but it is unclear how motivated cows are for access to pasture. FULL STORY »

Consider long straw to address foraging needs of limit-fed heifer

Limit-feeding of heifers offers the potential to reduce cost and improve feed efficiency FULL STORY »

Byproduct feeds can replace corn in the dairy cow’s diet

Byproduct feeds can be used to replace both forages and grain in dairy cattle diets. FULL STORY »

Growing dairy heifers prefer supplementary long straw

The objective of this study was to determine whether limit-fed heifers will choose to consume long particles, rather than short, of a low-nutritive feedstuff to ameliorate rumen function and meet foraging needs. FULL STORY »

It pays to cool dry cows as they approach lactation

When dry cows are cooled with fans and sprinklers during warm weather, they produce more milk in their subsequent lactation, research has shown. FULL STORY »

Estimating DMI in dairy heifers

A recent study conducted by a research team at the University of Wisconsin evaluated dry-matter intake (DMI) in more than 9,000 dairy heifers. FULL STORY »

Right feed bunk design can reduce shrinkage

Lowering feed shrinkage is an economic opportunity for dairies of every size. FULL STORY »
