Milk quality according to the daily range in farm production in the Mesoregion Central Mineira and Oeste of Minas Gerais regions, Brazil

Abstract

The objective of this work was to characterize milk production from the Central Mineira and Oeste Mesoregions regions in Minas Gerais State, Brazil, according to quality parameters such as somatic cell count, total bacteria count, and composition for specific production ranges. Average results for milk fat, protein, total and nonfat solids were compliant with Brazilian legal requirements (IN-62/2011) in all the production ranges selected. Average somatic cell counts (SCC) complied with the legal requirements of 600,000 cells/mL, except for the range with a daily production above 1,000 liters. However, average maximum values of 400,000 cells/mL are recommended for good milk quality. Total bacterial count was the most critical quality factor, with the highest values found in breeds with milk production above 500 liters per day.

Impact of farm size on milk quality in the Brazilian dairy industry according to the seasons of the year

“…It is typical from this region utilize crossbred animals. None of the herds in this analysis is composed of pure breed and the most used are Holstein and Gyr crossbreds (BORGES et al, 2013); however, the greater proportion of Holstein degree blood animals is observed for high production farms.…”

“…individual, breed, herd, region, year, month, SCC, lactation period, age, and milking period ). Despite the current common knowledge on the variation of SCC, TBC, fat and protein across the year and milk production, only a few studies have studied deeply these issues, even acknowledging its importance (GONÇALVES et al, 2014;BORGES et al, 2013). Thus, our objectives were to divide rural properties according to daily milk production, and to evaluate milk quality within each production scale throughout the seasons.…”

“…However, there are few studies proving or quantifying the lower quality of the milk produced on small properties, as described by ALLORE et al (1997), where they affirm that smaller herds would be more affected by higher levels of somatic cell count (SCC) than larger ones (BATTAGLINI et al, 2013;FRANÇA et al, 2017). Yet, consultants from several regions report the existence of small farms producing milk with high quality, or no correlation between farm range production and milk quality (BORGES et al, 2013;INGHAM et al, 2011), which reinforces the importance of studies tracing the quality profile of Brazilian dairy farms. Milk is considered to be of good quality when it contains properties such as pleasant taste, high nutritive value, absence of pathogens and contaminants, low SCC, and low microbial load.…”

Milk quality and financial management at different scales of production on dairy farms located in the south of Minas Gerais state, Brazil

“…Recent studies have studied some milk quality traits (milk composition and hygienic-sanitary aspects -SCC and TBC) and its association with different production scales (Borges et al, 2013;Bodenmüller et al, 2010), while others have studied technical and management efficiency of dairy farmers and its association with different scales of production (Fassio et al, 2005;Gonçalves et al, 2008;Lopes et al, 2008). However, there are no studies associating both milk quality traits and financial management of dairy farms within different scales of production.…”

Detection of antimicrobial and anthelmintic residues in bulk tank milk from four different mesoregions of Minas Gerais State - Brazil

“…The Central Mineira, Oeste of Minas, Triângulo Mineira/Alto Paranaíba and Metropolitana de Belo Horizonte mesoregions are important milk producing regions in Minas Gerais State, Brazil, with a settlement of several important dairy industries ( Figure 1). Raw milk collected in these regions supplies dairies with cheese, dry milk, yogurt, milk beverages, dessert cream, pasteurized and UHT milk production (Borges et al, 2013).…”
