ABSTRACT. We evaluated the physical and chemical characteristics of raw milk from goats supplemented with levels of Total Digestible Nutrients (TDN) in the dry period. Samples from 20 goats were divided into 4 groups, 3 groups received 400g concentrate per animal with different levels of TDN (65, 75 and 85%), and the control group (without concentrate). Four samples of milk were used for each animal, in four sampling periods, which were subjected to physical and chemical analysis. There was no significant difference between the treatments for the parameters of acidity and fat. The diet without concentrate presented higher value for the cryoscopic index. Mean values of the four treatments were within the range set by the Brazilian legislation for all parameters evaluated. The use of concentrate, containing 85% TDN in goat supplementation, was favored the physical and chemical characteristics of the milk during the dry period.Keywords: concentrate, legislation, raw caprine milk.Características físico-químicas do leite de cabras suplementadas com diferentes teores de nutrientes digestíveis totais durante o período seco do ano RESUMO. Este trabalho teve por objetivo avaliar as características físico-químicas do leite de cabras suplementadas com teores de Nutrientes Digestíveis Totais (NDT) no período seco do ano. Foram utilizadas amostras de leite de 20 cabras as quais foram divididas em quatro grupos, sendo que três grupos receberam suplementação de 400 g de concentrado por animal com diferentes teores de NDT (65, 75 ou 85%) e o grupo controle que não recebeu concentrado. Foram utilizadas quatro amostras de leite para cada animal, em quatros períodos de coleta, as quais foram submetidas à análise físico-química de acidez titulável, crioscopia e gordura. Não houve diferença entre os tratamentos para os parâmetros de acidez e gordura. As amostras de leite dos animais que receberam a dieta sem concentrado apresentaram maior valor para o índice crioscópico. As médias das amostras dos quatro tratamentos estavam dentro dos parâmetros fixados pela legislação brasileira para todos os parâmetros avaliados. A utilização de concentrado contendo teor de 85% de NDT na suplementação de cabras favoreceu as características físico-químicas do leite durante o período seco.Palavras-chave: concentrado, legislação, leite cru caprino.

ABSTRACT:This study was conducted jointly with the Municipal Sanitary Surveillance Agency of Petrolina, in the period of August-October 2013, to evaluate the hygienic-sanitary conditions of food producing and commercializing establishments in the municipality of Petrolina. A total of 300 food manufacturer/trader establishments were evaluated based on a Good Manufacturing Practices (GMP) checklist. The evaluation was based on 25 items. The data were computed as 0 for nonconformity and 1 for conformity to the GMP checklist. Data from all districts were analyzed by Principal Component Analysis (PCA). Items such as presence of lamp protectors, clean windows and screens, presence of SOP and training programs for handlers, use of aprons, caps, gloves and disposable towels, and performing periodic examinations of the establishments were evaluated. Fourteen evaluation items showed significant differences (P<0.05) for frequency of conforming and 9 for nonconforming. The PCA identified five city districts (Centro Norte, Areia Branca, Santa Luzia, Rio Corrente and São Gonçalo) in the municipality that used GMP in their establishments. These results highlight the need to redouble efforts in establishments to ensure the safety of products offered.
