Evaluation of metabolic status and milk compositions of indigenous cattle with subclinical mastitis and its amelioration by nutritional supplementations

Abstract

Indigenous cattle that were in early lactation and positive for subclinical mastitis were allocated into 2 groups; one group was administered with nutrional supplements (50 g mixture of vitamins A, D, E and thiamine, riboflavin, pantothenic acid, biotin, niacin, trisodium citrate dihydrate, methionine, manganese, copper, zinc, cobalt, selenium and live yeasts orally daily for 7 days), while other was kept as negative control. Milk composition of mastitic milk and metabolic status of affected cows were evaluated at day 0 and day 7 post-therapy. On day 0, remarkable alteration in milk composition as well as in metabolic status of affected animals was recorded in comparison to the healthy control. However, the altered nutrional panels as well as milk compositions were ameliorated toward normalcy at day 7 post-therapy in mastitic cows administered with nutrional supplements. At day 7 post-therapy, remarkable improvements in somatic cell count was also recorded in these cows when compared with day 0 values within the group, but the values were still significantly higher than the healthy control. Thus, subclinical mastitis in indigenous cattle could bestow remarkable alterations in milk compositions and metabolic status. The altered metabolic panels and milk compositions can be ameliorated toward normalcy by administering nutritional supplements.
