“…Increased competitiveness in the milk supply chain requires the production of high quality raw milk, which depends on milk processing, yield, and acceptability of dairy products (BOTARO et al, 2013). In order to characterize milk quality, the most commonly used criteria are hygiene milk composition, and sensory characteristics of consumer interest (BRANDT et al, 2010).…”

This study evaluated the effect of somatic cell count (SCC) on composition and hygienic quality of dairy herd bulk tank milk -specifically, the effect of SCC of bulk tank of dairy herds on composition (fat, protein, total solids, nonfat dry solids) and on total bacterial count (TBC), psychrotrophic count (PC) and coliform count (CC) were evaluated. A total of 230 dairy herds located south of Minas Gerais and west of São Paulo were selected based on SCC geometric mean obtained from five monthly analyses preceding the start of the sampling. The dairy farms were classified according to SCC in three groups: low (< 250,000 cells/mL, n = 84), medium (> 250,000 and < 750,000 cells/mL, n = 79) and high SCC (> 750,000 cells/mL, n = 67). After herd selection, bulk tank milk samples were collected every 14 days for three months totaling 1380 samples, which were subjected to analysis of composition, TBC, PC, and CC. A decrease of TBC and CC was observed in herds with low SCC; however, herds with medium and high SCC had an increase in fat, crude protein, and total solids contents. A medium correlation was observed between TBC and PC (r = 0.6215), and also between PC and CC (r = 0.3692). Based on hygiene indicators and milk composition, a low and negative correlation between TBC and fat (r = -0.0585), PC and fat (r = -0.0585), and PC and total solids (r = -0.0662) was observed. Dairy herds with SCC < 250,000 cells/mL had higher bulk tank milk hygienic quality; however, considering the composition, herds with higher SCC produced higher milk fat and protein concentration.

ResumoEste trabalho avaliou o efeito da contagem de células somáticas (CCS) na composição e na qualidade higiênica do leite de tanque de rebanhos leiteiros. Especificamente, foram avaliados o efeito da CCS do tanque de rebanhos leiteiros na composição (gordura, proteína, sólidos totais, extrato seco desengordurado) e nas contagens bacteriana total (CBT), de psicrotróficos (CP) e de coliformes (CC). Um total de 230 rebanhos leiteiros localizados no sul de Minas Gerais e oeste de São Paulo foram selecionados com base na média geométrica da CCS obtida de cinco análises mensais anteriores ao início das coletas das amostras. As fazendas foram classificadas de acordo com a CCS em três grupos: baixa (< 250.000 células/mL, n = 84), média (> 250.000 e < 750.000 células/mL, n = 79) e alta CCS (> 750.000 células/mL, n = 67). Após a seleção dos rebanhos, amostras de leite do tanque foram coletadas a cada catorze dias durante três meses, totalizando 1.380 amostras, as quais foram submetidas às análises de composição, CBT, CP e CC. Uma redução da CBT e da CC foi observada em rebanho com baixa CCS; entretanto, rebanhos com média e alta CCS tiveram aumento nos teores de gordura, proteína bruta e sólidos totais. Uma média correlação foi observada entre CBT e CP (r = 0,6215) e também entre CP e CC (r = 0,3692). Com base nos indicadores de higiene e na composição do leite, foi observada ...

“…A number of Brazilian dairies currently have in place compensation systems to producers with awards and penalties assigned to the liter price (L) of raw milk based on quality criteria, such as Total Bacterial Count (TBC), Somatic Cell Count (SCC), protein and fat contents, as an incentive for milk quality improvement (Roma et al, 2009). However, these programs have not increased the protein and fat content of raw milk supplied to dairies (Botaro et al, 2013).…”

The current pricing process of raw milk in Brazil discourages producers from improving milk composition, which affects both yield and quality of dairy products. Furthermore, small and medium-sized dairies face great difficulties when it comes to planning production. Thus, a linear programming model was developed to price the raw milk and determine the optimal mix (combination of quantities) of dairy products that maximizes total contribution margin (TCM) under daily scenarios of high (January) and low (July) raw milk supplies (summer and winter, respectively) by comparing optimal solutions with actual results. The TCM of optimal and actual mixes were higher in January due to the greater availability of raw material. Packaging was a limiting factor in the production of cheese in optimal mixes. The relationship between unit contribution margin (UCM) and the required amount of raw materials per product unit and resource availability is crucial to defining the mix of dairy products and TCM of the dairy. Casein and raw milk volume showed shadow prices. Under both scenarios, the calculated prices of raw milk were higher than the prices charged by the dairy and were higher in January. The proposed model remunerates the producers based on the quantity and quality of raw milk. The dairy can maximize its TCM by better planning its mix of products with the use of linear programming.

“…O número de unidades formadoras de colônias (UFC) é outro parâmetro importante para se avaliar a qualidade do leite produzido em propriedades leiteiras, que pode estar relacionado à ocorrência de mastites e também pela contaminação durante o processo de obtenção do leite, ou seja, os cuidados higiênicos estabelecidos no processo de ordenha, seja a nível animal, ordenhadeira e ambiental (Langoni et al 2011, Botaro et al 2013. Os procedimentos higiêni-cos na cadeia produtiva do leite são pontos críticos para a obtenção de matéria prima de qualidade.…”

A mastite é a principal afecção do gado destinado à produção leiteira, que impacta significativamente a cadeia produtiva do leite, com reflexos ainda para a saúde pública. Estudou-se aspectos relacionados à etiologia, celularidade e de contagem bacteriana em 10 propriedades leiteiras, localizadas no Estado Mastitis is the main affection of cattle intended for dairy production, which significantly impacts the milk production chain, with consequences yet to public health. It was studied aspects related to etiology, cellularity and bacterial count in 10 dairy farms, in the State of São Paulo. There were examined 1148 milking cows, totaling 4584 mammary glands. Cases in which there was isolation coagulase positive staphylococci (CPS) and coagulase-negative staphylococci (CNS) were considered. The results showed microbiota with various different pathogens and CNS (128 cases) and CPS (45), Staphylococcus aureus (90), Streptococcus agalactiae (70), Streptococcus dysgalactiae (69), Streptococcus uberis (29), Corynebacterium spp . (230), Klebsiella pneumoniae (28), Klebsiella oxytoca (2), Escherichia coli (15), Enterobacter spp. (3). The somatic cell count (SCC) related to CPS and CNS showed no differences among the evaluated properties, although with significant differences when evaluating the SCC between both groups of staphylococci, as evidenced by comparing discreet CNS and exuberant CPS (P <0.01), discreet CPS and exuberant CPS (P <0.001) and moderate SCN and exuberant SCP (P <0.01). The evaluation of SCC was related to the intensity of infection, considering how slight growth isolation of up to nine colonies, moderate ten to 29 colonies and lush, with 30 or more colonies, revealed for both groups of staphylococci that the higher the number of colony forming units (CFU), SCC is higher being larger in cases of CPS. The results indicate that the importance of both CPS and CNS when considering the high occurrence of the evaluated properties and the fact that it raises the SCC, which compromises the quality of milk. We conclude that when there is a larger number of CFU, is concomitantly higher SCC/ml of milk, in the case of CPS and CNS, which shows a direct relationship of the intensity of the infectious process with the response of milk cellularity, as well as the relevance of these in the etiology of mastitis and negatives aspects to both the production and the quality of milk produced in properties. INDEX TERMS: Milk quality, staphylococci, cellularity, colony forming units.
