Resumo: |
High somatic cell counts and high bacteria counts are related to health problems of the mammary gland and milking hygiene, what can bring harm to the industry, as well as to public health. The lactoperoxidase system acts directly on the mammary gland health generating hypothiocyanate ions, a bactericidal compound, wich concentrations depend, among other factors, on the presence of plants in the diet rich in cyanogenic glycosides. The objective of this study was to evaluate the quality of the milk in lactating Saanen goats fed maniçoba hay. Seven Saanen goats were used, with 39 ± 2,9 days of lactation and body weight 43,3 ± 7,6 kg in an statistical Latin square design 4 x 4. The treatments consisted of the replacement of the Tifton hay by maniçoba hay (0; 33,3; 66,7 and 100%). The concentrations of thiocyanate ions, fat, protein, lactose, total solids and dry extract in milk were not affected (P <0,05) neither by the substitution of tifton hay for maniçoba nor by the preservative. The SCC was lower (P <0,05) in samples without preservative and was quadratic affected of (P<0,0001) by the substitution of tifton hay for maniçoba. The total bacteria count increased significantly in milk samples without preservative, but was not affected by the substitution of tifton hay for the maniçoba hay. |
