Monitoramento do perfil celular, microbiológico e fisíco-quimico de cabras leiteiras da raça murciano-granadina em diferentes fases da lactação .

Abstract

Dairy goat farming in Brazil has been growing annually, particularly in the Northeast region. The expansion of the dairy sector comes primarily from small producers in the semi-arid region of the states of Pernambuco and Paraíba. The creation of milk processing programs in institutions has been an important factor in boosting production in recent years. The quality of goat milk is a highlight at trade shows, as the better the milk, the higher the quality of the derivatives it produces. One of the hotly debated issues is the intramammary infections that affect these animals, resulting in a drop in production, changes in their composition, and health risks for consumers. With these issues in mind, this study evaluated the microbiological, physicochemical, and somatic cell count (SCC) composition of milk from Murciano-Granadina goats. Samples were collected from six goats at seven different points during lactation. Samples were collected on days 0, 3, 7, 30, 60, 90, and 120 postpartum for physicochemical evaluation, somatic cell differentiation and counting, and microbiological growth on blood agar plates. The results showed a low incidence of microbiological growth in goats of this breed, demonstrating that the herd is composed of healthy goats. SCC counts and milk composition corroborate the health of these animals and also indicate their resistance to mastitis. The milk composition indicates a high amount of fat and total solids, which is favorable for the production of cheese and dairy products. Therefore, Murciano-Granadina goats have adequate milk production potential due to their resistance to intramammary infections and milk quality.
