KETOSIS AND SUBCLINICAL KETOSIS IN DAIRY CATTLE

Description

During the transition period, a significant frequency of health issues affects many dairy cows. High milk yielding cows often cannot meet the energy needs of the body after calving. This type of cow often has a negative energy balance in the first 6-7 weeks of lactation. In the last 2 weeks of birth, hormonal factors and decreased rumen capacity may lead to decreased nutrient intake and increased lipolysis. As a result, significant adipose tissue lipid mobilization, elevated oxidative stress, and weakened immunity are linked to an increased risk of periparturient health issues, such as ketosis or subclinical ketosis, which have a major negative economic impact on dairy productivity. Increased blood ketone bodies without any indications of clinical ketosis are referred to as subclinical ketosis. The incidence of subclinical events can reach 30-50% at the beginning of lactation in some herds, and when it is calculated that it causes 1-1.4 liters of milk loss per day, its economic size is large. Oral propylene glycol, injectable butaphosphan and cyanocobalamin, and controlled-release monensin capsules are among the options for managing and preventing subclinical ketosis.
