Dietary supplementation of essential oils in dairy cows: evidence for stimulatory effects on nutrient absorption [PDF]

, 2019
Results of recent in vitro experiments suggest that essential oils (EO) may not only influence ruminal fermentation but also modulate the absorption of cations like Na+, Ca2+ and NH4+ across ruminal epithelia of cattle and sheep through direct ...

Influence of cutting frequency and height on phytoestrogen levels in red clover and white clover

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Phytoestrogens are a class of secondary compounds naturally produced by some forage legumes, including red clover (Trifolium pratense L.) and white clover (Trifolium repens L.). Previous research showed that phytoestrogens can have beneficial and negative effects on animal health and reproductive function.

Feeding corn grain steeped in citric acid modulates rumen fermentation and inflammatory responses in dairy goats

Animal, 2019
Cereal grains treated with organic acids were proved to increase ruminal resistant starch and can relieve the risk of ruminal acidosis. However, previous study mainly focussed on acid-treated barley, the effects of organic acid-treated corn is still ...

Influence of Wheat Straw Pelletizing and Inclusion Rate in Dry Rolled or Steam-flaked Corn-based Finishing Diets on Characteristics of Digestion for Feedlot Cattle. [PDF]

, 2016
Eight Holstein steers (216±48 kg body weight) fitted with ruminal and duodenal cannulas were used to evaluate effects of wheat straw processing (ground vs pelleted) at two straw inclusion rates (7% and 14%; dry matter basis) in dry rolled or steam-flaked

A Mathematical Approach to Predicting Biological Values from Ruminal pH Measurements [PDF]

Journal of Dairy Science, 2007
The use of continuous recording to monitor ruminal pH has received growing attention. Continuous ruminal pH data are usually summarized for each 24-h period for each cow by calculating mean pH, maximum pH, minimum pH, amount of time (min/d) below pH 5.6 and 6.0, and area (time x pH) below pH 5.6 and 6.0.

Fermentation techniques for protein enrichment of cassava peel

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4384-4393, May 2026.
Abstract BACKGROUND The use of agro‐industrial by‐products such as unconventional feeds in animal production is an alternative for reducing the high costs associated with conventional feeds. The present study aimed to evaluate the effect of aeration, pH adjustment, the use of yeast (Saccharomyces cerevisiae) and the amount of urea on the enrichment of ...
