Loss of Stability for Blood Urea Nitrogen in Cattle Serum Samples Stored for 3 and 6 Months at −20°C and −80°C

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background Biological samples are stored for delayed or add‐on analyses. However, storage conditions, including time and temperature, can affect the stability of measurands in the samples. Objectives To assess the stability of blood urea nitrogen (BUN) in cattle serum samples.

Invited review: Ruminal acidosis and its definition—A critical review

Journal of Dairy Science
: Ruminal acidosis occurs as a continuum of disorders, stemming from ruminal dysbiosis and disorders of metabolism, of varying severity. The condition has a marked temporal dynamic expression, resulting in cases expressing quite different rumen ...

Influência da monensina no consumo e na fermentação ruminal em bovinos recebendo dietas com teores baixo e alto de proteína Effects of different dietary levels of monensin and protein on intake and ruminal fermentation in bovines

Revista Brasileira de Zootecnia, 2005
Foram utilizados quatro novilhos holandeses fistulados no rúmen e alimentados quatro vezes ao dia (8, 11, 14 e 17 h) com dietas contendo teores baixo e alto de proteína (baixo e alto), com e sem monensina, totalizando quatro dietas experimentais ...

Effects of Rosemary, Citronella, and Tea Tree Essential Oils on Fermentation Characteristics and Aerobic Stability of Sorghum Silage

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
Rosemary, citronella, and tea tree essential oils were evaluated as natural additives for sorghum silage at four inclusion levels (0, 500, 1000, and 2000 mg kg−1 of fresh forage). Rosemary essential oil improved fermentation by increasing crude protein while reducing ammonia nitrogen and butyric acid concentrations.

Effects of Perovskia abrotanoides Kar. Essential Oil on Greenhouse Gas Mitigation and Energy Efficiency Improvement in Sheep Rumen: An In Vitro Study

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The essential oil of Perovskia abrotanoides Kar. (rich in 1,8‐cineole and camphor) linearly reduced methane production (up to 57.5%) and total protozoa population in sheep rumen fluid in vitro. Simultaneously, it increased microbial biomass production, microbial synthesis efficiency and the partitioning factor, indicating improved rumen energy ...

High‐Starch Diet Prepartum Enhances IgG Concentration in Goat Colostrum Without Affecting the Transfer of Passive Immunity

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 741-752, September 2026.
ABSTRACT This study hypothesises that a high‐starch (HS) diet during the last month of gestation enhances colostrum yield and composition as well as the dam and goat kid metabolism, immune status and performance. Thirty multiparous and pregnant Majorera dairy goats were randomly assigned to a prepartum dietary treatment (CON vs.
