Occurrence of subclinical mastitis in female goats in and around Jabalpur

Abstract

Mastitis is the term used to describe inflammation of the mammary gland parenchyma, independent of the underlying etiology. Thus, a variety of physical and chemical alteration in the milk as well as pathological changes in the glandular tissue are characteristics of mastitis. Subclinical mastitis denotes the absence of gross abnormalities in the mammary gland, but presence of chemical and bacteriological changes in the milk. The loss of milk production in SCM is greater. Therefore, it is necessary to diagnose the disease when it is in subclinical phase. The modified California mastitis test was performed to detect the presence of SCM in the mammary gland. The present work was conducted in the Department of Veterinary Medicine, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur (M.P.), India. For occurrence study, A total of 236 lactating goats irrespective of age, breed, parity and stage of lactation belonging to both organized and unorganized sectors in and around Jabalpur were screened for a period of six month. On the basis of modified California mastitis test score, out of 236 lactating goats, 83 goats were found positive for subclinical mastitis with overall occurrence as 35.17% (83/236), however udder wise occurrence 30.69% (143/466). Sector wise occurrence of subclinical mastitis was significantly higher in goats reared under organized sector. Age wise occurrence was significantly higher in the goats of age group 4 and above years 48.10%. Breed wise occurrence was significantly higher in Sirohi 55.10% followed by Barbari 26.09%, non-descript 21.15% and in Black Bengal 9.09%. Parity wise occurrence was higher in goats of fourth and above parity 42.19%. Lactation stage wise occurrence was seen higher in late lactation stage 44.74%.
