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 ...

Heather moorland is recognized as having international importance, yet there has been a decline in the extent and condition of this habitat as a result of inappropriate management. In this experiment the diet composition ...

Pregnant Holstein heifers (450) and dry cows (417) within 3 weeks of calving (i.e., close up) were assigned to one of three groups. These groups were offered a low-CP (0.117 of DM) ration based on corn silage, alfalfa ...

The effect of adding water-soluble carbohydrate (WSC) on the microbial fermentation of fresh perennial ryegrass was examined in an in vitro RUSITEC system over two 10 day periods. Four treatment levels of WSC were used: a ...

Three experiments were conducted to evaluate the effect of a stay-green trait in perennial ryegrass (Lolium perenne) on concentrations of fatty acids as well as their susceptibility to peroxidation during wilting and to ...

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 ...
