Summer-long grazing of high versus low endophyte (Neotyphodium coenophialum)-infected tall fescue by growing beef steers results in distinct temporal blood analyte response patterns, with poor correlation to serum prolactin levels

Autor: Joshua J. Jackson, Merlin D. Lindemann, James A. Boling, James C. Matthews

Publikováno v: Frontiers in Veterinary Science, Vol 2 (2015)

Previously, we reported the effects of fescue toxicosis on developing Angus-cross steer growth, carcass, hepatic mRNA and protein expression profiles of selected serum proteins, and blood clinical and chemical profiles, after summer-long grazing (85

Grazing -infected forages results in a variety of reduced animal performance parameters, collectively known as "fescue toxicosis." The initial, limited evaluations of hepatic mechanisms affected by fescue toxicosis have used transcriptomic expression

Glutamine synthetase and alanine transaminase expression are decreased in livers of aged vs. young beef cows and GS can be upregulated by 17β-estradiol implants1

Aged beef cows (≥ 8 yr of age) produce calves with lower birth and weaning weights. In mammals, aging is associated with reduced hepatic expression of glutamine synthetase (GS) and alanine transaminase (ALT), thus impaired hepatic Gln-Glu cycle fun

Hepatic Transcriptome Profiles Differ Among Maturing Beef Heifers Supplemented with Inorganic, Organic, or Mixed (50 % Inorganic:50 % Organic) Forms of Dietary Selenium

Autor: Arnold J. Stromberg, James C. Matthews, Zhi Zhang, Jennifer D. Patterson, James A. Boling, Phillip J. Bridges

Publikováno v: Biological Trace Element Research. 160:321-339

Selenium (Se) is an important trace mineral that, due to deficiencies in the soil in many parts of the USA, must be supplemented directly to the diet of foraging cattle. Both organic and inorganic forms of dietary Se supplements are available and com

Individual Intake of Free-Choice Mineral Mix by Grazing Beef Cows May Be Less Than Typical Formulation Assumptions and Form of Selenium in Mineral Mix Affects Blood Se Concentrations of Cows and Their Suckling Calves

Autor: James A. Boling, W. R. Burris, James C. Matthews, Jennifer D. Patterson

Publikováno v: Biological Trace Element Research. 155:38-48

The objectives of this study were to determine (1) the individual ad libitum intake of mineral mix by beef cows managed under a year-long, fall-calving, forage-based production regimen and (2) if Se form in the mineral mix affected the blood Se conce

Selenium Content in Blood Fractions and Liver of Beef Heifers Is Greater with a Mix of Inorganic/Organic or Organic Versus Inorganic Supplemental Selenium but the Time Required for Maximal Assimilation Is Tissue-Specific

Autor: James C. Matthews, W. R. Burris, Kristen M Brennan, James A. Boling

Publikováno v: Biological Trace Element Research. 144:504-516

Selenium (Se) content of feedstuffs is dependent on the Se level of the soil. Even though Se in grass and forage crops is primarily present in organic forms, Se is commonly supplemented in cattle diets in an inorganic (sodium selenite) form in geogra

Publikováno v: Biological Trace Element Research. 140:151-169

In geographic regions where selenium (Se) soil concentrations are naturally low, the addition of Se to animal feed is necessary. Even though it is known that Se in grass and forage crops is primarily present in organic forms (especially as L-selenome
