Assessment of thyroid hormones, insulin and magnesium in dairy cattle with subclinical ketosis [PDF]

Āsīb/shināsī-i Darmāngāhī-i Dāmpizishkī, 2011
Ketosis, with ethologically energy deficiency, is one of the commonest metabolic diseases of dairy cattle. Assessment of some serum hormonal and metabolic status can be beneficent in prediction and diagnosis of subclinical ketosis.

Predicting ketosis during the transition period in Holstein Friesian cows using hematological and serum biochemical parameters on the calving date

Scientific Reports, 2022
Ketosis often occurs during the postpartum transition period in dairy cows, leading to economic and welfare problems. Previously, ketosis was reported to be associated with hematological and serum biochemical parameters.

Association of rumination time with subclinical ketosis in transition dairy cows [PDF]

Journal of Dairy Science, 2016
The objective of this study was to characterize the relationship between rumination and subclinical ketosis (SCK) in transition dairy cows. A study was conducted on 4 commercial dairy farms in eastern Ontario, Canada. A total of 339 Holstein dairy cows (107 primiparous and 232 multiparous) were monitored for rumination activity and SCK from 14 d before

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

Animal Research and One Health, Volume 4, Issue 2, Page 198-212, May 2026.
(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.

Identification of novel pathways in pathogenesis of ketosis in dairy cows via iTRAQ/MS

Journal of Veterinary Research, 2016
Introduction: To identify novel pathways involved in the pathogenesis of ketosis, an isobaric tag for relative and absolute quantitation/mass spectrometry was used to define differences in protein expression profiles between healthy dairy cows and those ...

Characteristics of Holstein cows predisposed to ketosis during the post‐partum transition period

Veterinary Medicine and Science, 2023
Background Ketosis is a common metabolic disorder during the post‐partum transition period of dairy cattle. How the method of reproduction, parturition time, and calf birth weight affect the occurrence of ketosis on dairy herds remains elusive ...

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

Animal Research and One Health, Volume 4, Issue 2, Page 145-166, May 2026.
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.

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, Volume 4, Issue 2, Page 167-184, May 2026.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Alterations in biochemical parameters and hepatic ultrasonography with reference to oxidant injury in ketotic dairy cows [PDF]

Benha Veterinary Medical Journal, 2016
This study aimed to evaluate the clinical, biochemical and hepatic ultrasonographic changes in ketotic dairy cows. Forthat purpose, we examined 42 lactating Holstein- Friesian cows with ages from 3- 10 years old during the post parturientperiod (up to 6 ...
