Relationship between body condition score and body composition in dairy cows [PDF]

New Zealand Journal of Agricultural Research, 1998
Abstract The relationship between body condition score and physically dissected body composition was assessed in forty cull Friesian and Friesian‐cross cows. Body condition score was assessed using the New Zealand condition scoring system which is based on the contours of the cow from its hooks to its hocks.

INFLUENCE OF BODY CONDITION SCORE ON BLOOD METABOLITES AND OXIDATIVE STRESS IN PRE- AND POST-CALVING OF FRIESIAN DAIRY COWS IN EGYPT

Slovenian Veterinary Research, 2019
This experiment aimed to study the relation of body condition score (BCS) with blood metabolites in dairy cow. At 8 weeks before expected parturition, 90 multiparous Friesian dairy cows were divided according to their body condition score into 3 groups:

Body condition score prior to parturition is associated with plasma and adipose tissue biomarkers of lipid metabolism and inflammation in Holstein cows

Journal of Animal Science and Biotechnology, 2018
Background Previous research has revealed a strong inflammatory response within adipose (AT) tissue during the transition into lactation. Whether this effect is a result of oxidative stress induced by lipolysis and fatty acid oxidation associated with ...
