Abstract
The purpose of this study was to monitor improvements in the hygiene and sanitation conditions, and milk safety after application of Good Manufacturing Practices (GMP) to milking. A total of 106 farms were assessed in four stages of six months in the regions named agreste, dairy region, mid-backlands and high backlands of Alagoas. Two activities were executed in the project: monitoring of milk quality and safety; and application of GMP to pre-milking and milking processes. Milk samples underwent determination of Somatic Cell Count (SCC), Total Bacterial Count (TBC) and composition. The results correspond to milk components, determination of mammary health indicative parameters - SCC and milking hygiene - TBC. Regarding SCC, 73% of producers complied with the standards established by normative instruction IN 62 as of 2017. Regarding TBC, the use of GMP increased from 46.75% to 59.87% the average of all assessed properties that complied with the established standards. Less than 4% of the properties presented one million or higher TBC/mL of milk. Results of SCC after application of GMP remained basically the same. Regarding TBC, rate changes deriving from the application of GMP were significant.
Highlights
Researchers from several regions of the Brazil and in the world have been directing their attention to the search for more suitable milk quality
Three questionnaires were applied to each one of the farms: 1. General questions about mastitis and milk quality considering the current legislation - assessed before and after application of Good Manufacturing Practices (GMP). They concerned the data about production and general management of each herd and were used to understand the production system, obtain information related to production, consumption and processing of milk, in addition to specific information about prophylaxis and hygienic measures applied to milking, transportation and milk conservation
Regarding Somatic Cell Count (SCC) (Table 1), results refer to the average of all periods of study in all farms in the four groups
Summary
Researchers from several regions of the Brazil and in the world have been directing their attention to the search for more suitable milk quality. According to Huijps et al (2008), the economic losses of a clinical case in a default situation were calculated as €210, varying from €164 to €235 depending on the month of lactation and is important to show the farmers the economic losses of mastitis on their farm. In another study on USA, Rollin et al (2015) showed detailed costs of mastitis and the average case of clinical mastitis resulted in a total economic cost of $444, including direct costs ($128) and indirect costs ($316). Rollin et al (2015) showed the costs of therapeutics ($36), non-saleable milk ($25) and death loss ($32). Indirect costs included future milk production loss ($125) and premature culling and replacement loss ($182)
