ABSTRACT This study investigated the relationship between metabolic disease, milk fatty acid composition, and rumination time in early lactation dairy cows and evaluated their utility as diagnostic indicators. Twenty‐two Holstein dairy cows were monitored for 8 weeks postpartum, with weekly milk and blood sampling and continuous rumination monitoring ...

Assessment of the Herd Management Effects on Mastitis Frequency in Austrian Dairy Farms
ABSTRACT Mastitis, an inflammation of mammary tissue caused by infection, physical injury, or chemical irritation, is one of the most economically significant diseases in the global dairy industry. Both acute and chronic forms of mastitis lead to an increase in somatic cell counts (SCCs) in milk and a significantly reduced milk yield.

Metabolic disorders in dairy Simmentals - prevalence risk and effect on subsequent daily milk traits
In order to analyse metabolic disorders in Simmental cows, 2.641.223 test-day records have been used. The metabolic disorders prevalence risk was indicated by the fat to protein (F/P) ratio, while the subclinical disorder was demonstrated using the F/P ...

A STUDY OF SUBCLINICAL KETOSIS IN COWS IN BASRA PROVINCE
Subclinical ketosis (SCK) is defined as elevated concentrations of circulating ketone bodies in the absence of clinical signs. Measurement of blood β-hydroxy butyric acid (BHBA) concentration is considered as the gold standard method to detect SCK. The objective of this study was to determine the presence of SCK in cows in different physiologic status ...

Efficacy of Monensin for the Prevention of Subclinical Ketosis in Lactating Dairy Cows
A total of 1010 dry cows and pregnant heifers was randomly selected from 25 dairy farms near Guelph, Ontario, Canada to receive either a controlled-release capsule of monensin or a placebo at 3 wk prior to expected calving. Serum samples were obtained at the time of treatment administration, and both serum and milk samples were collected at wk 1, 2, 3,

RELATIONSHIP BETWEEN SOME BIOCHEMICAL PARAMETERS IN HEALTHY AND DAIRY COWS WITH SUBCLINICAL KETOSIS
The aim of the presented study is to compare beta-hydroxy butyric acid (BHBA), glucose (GLU) gamma-glutamyl transferase (GGT), phosphorus (P), calcium (Ca), and albumin (Alb) values of healthy animals and animals suffering from subclinical ketosis.

Evaluation of the levels of Leptin, Beta hydroxyl butyrate, Glucose, Cholesterol and Triglyceride in serum of Holstein cows with sub clinical ketosis [PDF]
Leptin hormone is secreted from the white adipocytes of adipose tissue and its levels increase with the increase in size of the adipose tissue. One of the most important actions of this hormone is the regulation of body metabolism by consuming adipose ...
