MASTITE BOVINA: UMA REVISÃO

The mastite, inflammation process of mammary gland, characterized by a decrease in production and changes in milk composition, is considered the disease of major impact for dairy cattle in Brazil. Normally, this disease is resultant of the action of infectious agents, and may be involved different species of virus, fungi, and mainly, bacteria. It is important to remember, that the mastite, of any form and effect, reduces milk production and, in severe cases, may occur loss of one or more teats. Thus, the control of bovine mastite is important for the milk production of high quality. The aim of study is develop a study about this pathology that affects the dairy cattle and their effects in production and quality milk, and consequently, farmers, dairy industry and their products.

CONTAGEM DE CÉLULAS SOMÁTICAS, CONTAGEM BACTERIANA TOTAL E ANÁLISESFÍSICO-QUÍMICAS DO LEITE PRODUZIDO NA REGIÃO SUL DO ESTADO DE GOIÁS

Considering that the production of milk in the State of Goiás has undergone changes in the productive chain that reflect directly in the national scenario, studies are needed to obtain information on the quality of milk produced in this region. The present work was carried out in partnership with the cooperative receiving the milk production of the rural properties studied. The objective of this study was to evaluate the incidence of somatic cell count (CCS), total bacterial count (CBT) and the physicochemical composition of dairy herds in the southern region of the state of Goiás. The data of CCS, CBT and physicochemical analyzes were tabulated, from of period of August of 2015 to July of 2016. The samples were collected monthly in the cooling pond of the farms and sent to a laboratory accredited by the Brazilian Quality Milk Network (RBQL). High values were found in the CCS, however, remaining within the limits allowed by Normative Instruction 62. For CBT were found alarming results, as they were indexed beyond what is allowed by the regulation. Regarding the physical-chemical composition variables, this study were used
