| description | Present study was conducted in Kerala Veterinary and Animal Sciences University farms,
various organized and unorganised farms and individual households in Thrissur district during the
period of May 2021 to April 2022 with the objectives of estimation of prevalence of subclinical ketosis
(SCK) by screening dairy cows on 14th and 28th day post-partum. Multiparous cows with a blood
beta-hydroxy butyrate (BHB) value ≥ 1.2 mmol/L without any overt clinical signs were considered
as positive for SCK. One hundred and fourteen animals from second to seventh lactation were
screened for SCK. Prevalence of SCK was 23.7 per cent on 14th day and 14.04 per cent on 28th
day with a total prevalence of 27.2 per cent. Occurrence of SCK was highest in animals in second
lactation (54.8 per cent) with more occurrence in crossbred Holstein Friesian cows. Maximum
number of positive cases were observed in dairy cows of age between four to six years (54.8 per
cent). Body condition score of diseased animals were higher than normal animals.
Prevalence was highest in animals calved between months of July to September and 58.1
per cent of affected animals had male calf. Concurrent abnormalities during transition period were
also assessed based on clinical examination and farm records. |
