Two experiments were conducted to investigate the basis for higher voluntary intakes and increased {alpha}-linolenic acid content in milk from cows offered clover silages. Six cows with rumen and duodenal cannulae were ...

A relatively small proportion of the nitrogen (N) consumed by the ruminant is transferred into meat (5-15%) or milk (15-30%), and most of the rest is excreted, with potential impacts on water, soil and air quality. Many ...

To investigate the effect of red clover formononetin concentration on lamb growth rate and carcass characteristics, 20 lambs (10 ewe lambs and 10 wethers) were grazed on each of three forages : red clover with a high ...

Four mature Holstein-Friesian dairy cows were used in a 4 x 4 Latin square change-over design experiment made up of four 4-wk periods to investigate the relationship between microbial protein flow to the duodenum and ...

We offered 43 Holstein-Freisian dairy heifers that calved for the first time at either 2 or 3 yr of age ad libitum access to ryegrass silage and a standard concentrate allowance of either 2 or 7 kg/d from the middle to the ...

Bacterial protein supply from the rumen is frequently low in animals fed on silage-based diets, partially because of the lack of rumen available sources of energy. An in vitro experiment was designed to determine the optimum ...

The UC Davis Dairy Cattle Day program is an outreach activity of the campus sponsored by the Department of Animal Science and the Dairy Research and Information Center. The goal of Dairy Cattle Day is to extend information ...

Twelve multiparous Holstein–Friesian dairy cows in early lactation were used to investigate the potential of using perennial ryegrass (Lolium perenne) with a high concentration of water-soluble carbohydrates (WSC) to ...
