Simple Summary Chronic inflammatory diseases could impact central nervous system homeostasis, being oxidative damage of the dorsal horn, a relevant mechanism mediating central sensitization. Chronic inflammatory lameness in dairy cows is a painful condition that affects animal welfare, affecting ...
An observational study was conducted in 59 Chilean dairy farms to evaluate bulk tank milk selenium (Se) concentration, and its association with measures of milk production parameters and udder health, measured as bulk tank somatic cell count. Fifty-nine dairy herds from Southern Chile were select...
Forage turnip (Brassica rapa L.) is used as a supplementary feed for grazing cattle in summer. The aim of this study was to evaluate the effect of two levels of forage turnip supplementary feed on milk production, and energy and protein metabolic responses in grazing dairy cattle during summer. 1...
In order to evaluate the effect of supplementation with two sources of selenium (Se) in blood and colostrum Se concentration in cows and their offspring, fourty three Holstein pregnant cows were used. Cows were randomly divided into three groups, and thirteen cows were supplemented one month befo...
The aim of this study was to propose reference intervals (RI) for blood markers of mineral balance in prepartum and lactating groups of dairy cows in the South of Chile. The blood concentrations values of calcium, inorganic phosphate, magnesium, sodium, potassium, copper and zinc and ratio calciu...
The ionophore lasalocid has been approved for use as a ruminant feed additive in many countries. This paper describes a simple and rapid method for the determination of lasalocid in cow milk using high performance liquid chromatography with ultraviolet detection. The method is specific for the an...
Physiological measures, such as blood variables, are commonly used to assess the welfare state of animals. The basal concentration of indicators such as plasma cortisol, white blood cells, cytokines, and indicators of oxidative stress could vary depending on the coping style of individuals. In th...
In order to evaluate the effect of selenium and alpha-tocopherol supplementation on the immune response to Brucella abortus strain RB51, four groups of six grazing heifers were used. Three months before the start of the trial, the groups Se-T and Se were supplemented in single dose with barium se...
Concentrations of calcium, magnesium, copper, zinc, and selenium were measured in plasma from 11 huemul (Hippocamelus bisulcus) from Chilean Patagonia. Except for zinc and copper, concentrations of these minerals were similar to those of other deer species.
