to examine the effects of different sources of rumen-degradable carbohydrates on rumen fermentation, nitrogen metabolism and performance of holstein dairy cows, four lactating holstein cows fitted with rumen cannulae in a 4×4 latin square with four diets and four 28 day periods each, were employed. experimental diets contained different levels of pure sucrose and corn starch in which sucrose wa...

Eight multiparous, ruminally cannulated Holstein cows averaging 40 d in milk and 575 kg BW at the start of trial were in a replicated 4 x 4 Latin square arrangement (28-d periods) to determine the effects of dietary nonfiber carbohydrate (NFC) level and Aspergillus oryzae fermentation extract (AO) on intake, milk production, and nutrient digestibility. Treatments were 42 or 35% NFC and 0 or 3 g...

Intercropping legume with cereal is an extensively applied planting pattern in crop cultivation. However, forage potential and the degradability of harvested mixtures from intercropping system remain unclear. To investigate the feasibility of applying an intercropping system as a forage supply source to ruminants, two consecutive experiments (experiments 1 and 2) involving a field cultivation t...

Drug information sources use category labels to assist in navigating and organizing information. Some category labels describe drugs from multiple perspectives (e.g., both structure and function). The National Drug File - Reference Terminology (NDF RT) is a drug information source that augments a "legacy" categorization system with a formal reference model specifying Chemical Structure, Cellula...

A new in vitro lab assay has been developed by UW-Madison Dairy Scientists that predicts total tract NDF digestion in ruminants. The in vitro TTNDFD assay predicts NDF digestion of alfalfa, corn silage, grass forages and byproduct feeds. UW-Madison researchers have validated the accuracy of the in vitro TTNDFD test against directly measured NDF digestibility lactating dairy cattle. The Universi...

Neu differentiation factor (NDF, also called heregulin) is a 44-kilodalton glycoprotein that stimulates tyrosine phosphorylation of the Neu/HER-2 receptor and induces phenotypic differentiation of certain mammary cancer cell lines to growth-arrested and milk-producing cells. To determine which molecules participate in the concomitant morphological alterations, we analyzed the expression of seve...

This study compared the effects of drying on beet pulp with and without added molasses by measuring the in sacco digestibility and composition including ®ber polysaccharides and minerals. Beet pulp was sampled before and after the addition of molasses from four different sugar processing plants within California. These samples were sub-sampled and then sun-, freeze-, or airdried. The percentage...

Our objective was to characterize changes in cell wall composition and digestibility of sugarcane bagasse, pith from bagasse, and wheat straw after treatment with alkaline hydrogen peroxide (AHP). The AHP treatment solution contained 1% H2O2 (wt/vol) maintained at pH 11.5 with NaOH. The H2O2 in solution amounted to 25% of the quantity of substrate treated. After treatment, residues were washed ...
