Compensation Response to Hepatic Gluconeogenesis via β‐Hydroxybutyrylation of FBP1 and PCK1 in Dairy Cows

open access: yesAnimal Research and One Health, EarlyView.
(1) Kbhb modification of FBP1 and PCK1 is involved in regulation of the gluconeogenesis pathway. (2) Kbhb of FBP1 and PCK1 is catalyzed by p300 and removed by HDACs. (3) BHB induced an increase in the enzymatic activity of FBP1 and PCK1 through Kbhb modification at the K43 site of FBP1 and the K191 site of PCK1.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

open access: yesAnimal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

open access: yesAnimal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Determination of selenium speciation in the muscle, kidney, and liver from different animals treated with different selenium supplements by HPLC‐ICP‐MS

open access: yesAnimal Research and One Health, EarlyView.
Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.
