Modeling Ruminal pH Fluctuations: Interactions Between Meal Frequency and Digestion Rate
Journal of Dairy Science, 1997 A steady periodic analysis of ruminal carbohydrate digestion was developed to predict the effects of diet and frequency of eating on ruminal pH fluctuation. Tests of the model against previous data showed that pH fluctuations were too large when previously published rates of carbohydrate digestion were used but were improved using rates from an in ...

Random changes in the heifer rumen in bacterial community structure,physico-chemical and fermentation parameters, and in vitro fiber degradation [PDF]
, 2011 The variability over time of several main ruminal characteristics was studied in heifers over 15 consecutive weeks. Three heifers were assigned to a low-fiber diet (27% NDF) and three to a high-fiber diet (44% NDF).

Feed intake pattern, behaviour, rumen characteristics and blood metabolites of finishing beef steers offered total mixed rations constituted at feeding or ensiling [PDF]
, 2009 peer-reviewedTwo experiments were undertaken. In Experiment 1, behaviour, intake pattern and blood metabolites, were recorded for steers offered total mixed rations (TMR) based on grass silage and concentrates, and constituted either at ensiling (E-TMR)

A novel model to explain dietary factors affecting hypocalcaemia in dairy cattle [PDF]
, 2011 Most dairy cows exhibit different degrees of hypocalcaemia around calving because the gestational Ca requirements shift to the disproportionately high Ca requirements of lactation.

Rumen pH as a Factor for Controlling Feed Intake in Ruminants
Journal of Dairy Science, 1967 Abstract Four rumen fistulated steers, in a 4×4 Latin-square design, received intraruminal infusions of a) water, b) phosphoric acid, c) lactic acid, or d) citric acid, to study the effect of rumen pH on daily hay consumption. Steers were fed chopped hay ad libitum for a 6-hr period daily.

Effect of Lupinus albus as protein supplement on yield, constituents, clotting properties and fatty acid composition in ewes' milk [PDF]
, 2006 The effect of feeding lupin seeds (Lupinus albus L.) as an alternative protein source in ewe diets was investigated. Two groups of 18 Sarda ewes were fed two different isonitrogenous diets: with lupin (L) seed, given after 12 h soaking, or soybean meal ...

Live yeast as a possible modulator of polyunsaturated fatty acid biohydrogenation in the rumen [PDF]
, 2010 In dairy cows, several studies focused on the effects of sodium bicarbonate and fibre on ruminal linoleic acid (c9c12-C18:2) biohydrogenation (BH) whereas literature is scarce about the effect of live yeast, used as a feed additive. The objective of this
