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. |

Dissertação (Programa de Pós-Graduação em Zootecnia) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/6850High 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.

O sistema lactoperoxidase atua diretamente sobre a saúde da glândula mamária gerando íons hipotiocianato, composto de ação bactericida, cujas concentrações dependem, entre outros fatores, da presença na dieta de plantas ricas em glicosídeos cianogênicos. Objetiva-se com o presente trabalho avaliar a qualidade do leite de cabras Saanen em lactação alimentadas com feno de maniçoba. Foram utilizadas sete cabras Saanen, com 39 ± 2,9 dias de lactação e peso corporal médio de 43,3 ± 7,6 kg em um delineamento estatístico quadrado latino 4 x 4. Os tratamentos consistiram da substituição do feno do capim tífton por feno de maniçoba (0; 33,3; 66,7 e 100%). As concentrações de íons tiocianato, gordura, proteína, lactose, sólidos totais e extrato desengordurado no leite não foram influenciadas (P < 0,05) pela substituição do feno de tifton por feno de maniçoba nem pelo conservante. A CCS foi menor (P < 0,05) nas amostras sem conservante e foi influenciada de forma quadrática (P < 0,0001) pela substituição do feno de tifton por feno de maniçoba. A contagem de bactérias totais aumentou significativamente nas amostras de leite sem conservante, mas não foi influenciada pela substituição do feno de tifton por feno de maniçoba.Submitted by (lucia.rodrigues@ufrpe.br) on 2017-05-09T15:36:26Z No. of bitstreams: 1 Ney Braulio de Oliveira Lins.pdf: 535128 bytes, checksum: bf7b656b16605ec0590fcb36feaac735 (MD5)Made available in DSpace on 2017-05-09T15:36:26Z (GMT).

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.
