This development is also sustained in this study, based on the comparative monitoring of the health and conformity indices of milk acquired from traditional collecting centers and from close circuit farms belonging to a processing company. The quality of Saint Cyprinien Dating Site milk derived from the two collecting sources situated in the central area of Transylvania was analyzed in comparison, based on the data obtained in the auto-control tests performed by the processing company.

The analysis of this investigated parameters indicated very high level of conformity for the freezing point In contrast, for the aerobic plate count APC and for the somatic cell count SCC data showed a very high degree of compliance to standards in case of milk collected from farms with closed systems The results confirmed the quality level of the feed floristic composition, welfare and health of lactating cows in closed circuit farms, in comparison with those found in traditional collecting centers.

The global analysis of the obtained values reveal high level of cellular and microbial content in the milk mixture subjected to processing, showing a low level of compliance to standards Key words: feed base, lactating cows, milk conformity, processing, dairy products Introduction The increase of feed quality, safety, security and traceability of dairy products requires the integration of the production, processing and development procedures in the current concept of the milk chain Râmniceanu, The implementation of these complex forms of management in the commercial company is based on the functioning of integrated systems for health surveillance of the animal- dairy product —consumer chain Ognean, ; Farnworth, These kind of chains offer advantages regarding the integrated monitoring of feed quality and health of lactating cows, evaluated on the basis of hygienic and sanitary parameters of Femeie singura pentru intalnire collected Saint Cyprinien Dating Site and processed products Turek et al.

A large part of commercial farms are fitted with automatic systems, which verify cellular content and electric conductibility of milk, in order to monitor the conformity and health of the produced milk Carey, ; Harmon, ; Ognean et al.

This study is also focused in this direction, for evaluating the conformity degree of milk collected from different areas with the European standards, regarding the fact that in our country the proportion of conform milk is still low Giurcaet et al.

The related facilities were at the same standards: veterinary practices, lockers, bushing whit separate milking facility. Milking procedure involved the use of Flirt Dating Opinii music to stimulate the lactoejection, and measures of hygiene and monitoring of mammary health: removing the first jets and their examination by Contrast tests Rotaru and Ognean, ; cleaning and disinfection of the udder before milking individual pads ; monitoring the electric conductibility of the milk mS and disinfection of the udder after milking with protective film-forming solutions.

În anulLavoisier prezintă ideea de bază a circulaţiei materiei în natură, iar în anulPasteur descrie mersul descompunerii materiei organice moarte, aspecte esenţiale pentru înţelegerea proceselor ecologice.

Using collection tanks with automatic programming and automatic systems for wash and disinfection, the condition of hygiene and cooling of the milked milk were also assured. The strategy for detection of mammary infections based on the computerized monitoring of milk electric conductibility or based on the results to Contrast and Waikato tests had a major impact Ognean, ; Rotaru and Ognean, The cows diagnosed with mastitis during lactation were mainly treated with intra-mammary antibiotic suspensions Mastiject, Sinulox and milked separately during the waiting period.

For the health surveillance of the lactating cows and milked milk we resorted to periodic evaluation of the ketone bodies level, using Ketostiks bands and the individual determination of basic milk physico-chemical parameters fat, protein, dry matter, density, freezing point, titratable aciditywith Ecomilk equipment Sabău and Rotaru, Performed investigations.

Representative samples were collected from the raw milk and dairy products and were subjected to the physico-chemical, microbiological and cytological testing.
