Abstract

Mastitis causes economic damage to dairy farmers, which mainly affects milk production and in turn is considered one of the main frequent diseases in dairy production that results in reduced production, loss in milk quality as well as quantity due to discarded milk, treatment costs and extra labor costs. The health of the mammary gland in buffalo can be influenced by several factors, including the soil and climate characteristics in which the female is located, as well as the type of immune response to microorganisms that cause mastitis. In view of the preciousness of the species and its intensive and extensive characteristics of the activity, such as the potential contribution that the information can also add to other production systems. It is necessary to understand the scenario of mastitis and the relationship of the disease in these animals, as well as understanding the context of the main invasive microorganisms and regional particularities, to better institute prophylactic and treatment measures for the disease. Since this species is considered more resistant to infection. Furthermore, the relevance of the health of the mammary gland and bubaline milk products has been increasingly highlighted in the world literature.

Abstract

The objective of the present study was to evaluate different methods for indirectly diagnosing mastitis during the postpartum period. These methods were: automatic and microscopic somatic cell counting (SCC), the California Mastitis Test (CMT) and Somaticell®. A total of 538 milk samples from 34 cows were used. These were collected at six times: day of parturition (M1) and 3 (M2), 7 (M3), 15 (M4), 21 (M5) and 30 (M6) days after parturition. Automatic and microscopic SCC, CMT and Somaticell® were all able to detect mastitis during the immediate postpartum period (up to 3 days postpartum). However, higher cut-off values should be applied to automatic and microscopic SCC. The negative score (score 0) of CMT was considered to be the best cut-off point at all times. Moreover, the values found using the Somaticell® test should not be used to presume the automatic SCC values, since there are discrepancies between the values of Somaticell® and automatic and microscopic SCC. It can be concluded that the different methods evaluated here to milk cellularity can be applied for diagnosing bovine mastitis, even during the immediate postpartum period, when there is greater cellularity, such as in the colostrum and transition milk.
