| ABSTRACT: The treatment of dairy cattle with antibiotics may lead to milk contamination by drugs residues, which represents risks to human health. This study aimed to investigate the presence of antibiotic residues in milk, produced and marketed in Capanema microregion, Paraná, Brazil, through the analysis of pasteurized milk samples from different brands consumed by the local population and unpasteurized milk samples provided by a dairy industry. Enzyme immunoassays screening kits SNAPduo™ Beta-Tetra ST Test (Idexx Laboratories) were used, which verified the presence of β-lactam and tetracyclic drugs residues, as well as enzyme immunoassays screening kits Charm ROSA Test (Charm Sciences), which established the presence of quinolones and sulfonamides... |

| The objective of this work was to evaluate the effect of somatic cell counts (SCC) in casein fractions of ultra high temperature (UHT) milk. Raw milks were categorized in SCC groups of low (200,000-320,000 cells mL-1), intermediate (380,000-560,000 cells mL-1) and high cells (600,000-800,000 cells mL-1). Five replicates of UHT milks within each SCC category were analyzed for casein fractions after 8, 30, 60, 90 and 120 days of storage through high performance liquid chromatography. SCC showed effect only on beta-casein reduction. SCC in raw milk increases the proteolysis of UHT milk, as a consequence of beta-casein degradation. |

| Abstract: The objective of this work was to evaluate the chemical composition and fatty acid profile of milk from F1 Holstein/Zebu cows in different lactation periods, when receiving different levels of dietary supply in percentage of body weight. Sixty cows were evaluated, with five levels of dietary supply and three lactation periods. The levels of dietary supply had no effect on the production of milk corrected to 3.5% fat (12.25 kg per day). There was also no effect of dietary supply levels, in the different lactation periods, on contents of fat (3.34%), protein (3.41%), lactose (4.60%), total solids (12.0%), defatted dry extract (8.80%), and urinary nitrogen (14.5 mg dL-1), nor on somatic cell count (89.98 mL-1). As the dietary supply level was... |

| K-casein gene polymorphisms are of major importance in the dairy industry due to their association with different quality and productive traits (i.e., milk protein). Several methods for genotyping this gene have been proposed; however, none are focused on the simultaneous discrimination of nine K-casein variants. A strategy based on PCR-RFLP was designed to characterize nine K-casein variants (A, B, C, E, F², G, H, I and J) and used to genotype three cattle populations: Gyrholando (3/8 Gyr x 5/8 Holstein), Charolais and Carora. The B variant was the most frequent in the Charolais and Carora breeds, with allelic frequencies of 0.60 and 0.59, respectively. In the Gyrholando breed, four variants were found, with the A variant being the most frequent and E and... |

| The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increasing the levels of healthy fatty acids (FA), such as conjugated linoleic acid and omega-3 FA, in milk and cheese in the human diet. In addition, the use of alternative feed resources such as by-products, aromatic plants, and phenolic compounds in the sheep diet and their effects on milk and cheese FA composition are also discussed. Among feeding strategies, grazing and the use of supplements rich in oils... |

| ABSTRACT The aim of this study was to evaluate the frequency of isolation of agents causing subclinical mastitis in a herd and to estimate production losses associated with SCC> 200,000cells/mL. Three 7-day interval microbiological cultures were performed in all lactating animals from the same farm that was evaluated from June to July. To evaluate the negative and positive isolation frequencies between the lactation phases, a Chi-square test was performed. Simple linear regressions were performed to evaluate the lactation curve of animals grouped by pathogens isolated from negative cows in the microbiological culture and with SCC <200,000cells/mL. To estimate the production losses between the groups, regression coefficients were used. Results found... |

| ABSTRACT Mastitis caused by Mycoplasma spp., regardless of species, are considered highly contagious pathogens and, usually was not responsive to antimicrobial therapy. Five dairy herds, comprising 489 animals and 1,956 mammary glands, were used in this study. Milk samples were obtained from bulk tanks and subjected to polymerase chain reaction (PCR) for the identification of Mollicutes, Mycoplasma spp., and Mycoplasma bovis. Moreover, individual samples from cases of clinical and subclinical mastitis in quarters of the dairy herds’ animals that yielded a positive PCR upon bulk tank analysis were subjected to molecular analysis. Only one bulk tank was positive for class Mollicutes by PCR. All positive samples classified as mastitis teats had their DNA... |

| ABSTRACT: Milk produced in Brazil has been seen as having poor quality and is associated with a large number of small farms. However, there are few studies demonstrating lower quality of milk of small properties. Thus, this study aimed to evaluate the relationship between production scale on dairy farms and milk quality, how it behaviors throughout the year and set goals to improve quality according to each strata. A total of 21,917 analysis of 409 farmers conducted from January 2005 to December 2014 were used. To study the database, the properties were divided according to monthly average daily milk yield: 10 to 100; 100 to 200; 200 to 500; 500 to 1,000; and 1,000 to 5,000L of milk day-1. The data showed that dairy farming is predominantly carried out on... |

| The objective of this study was to evaluate the influence seasons of the year and somatic cell counts (SCC) on physical-chemical and sensory parameters of cow’s milk from individual and collective refrigeration tanks with different milking systems. In addition to analyzing the sensory acceptance of pasteurized milk and coalho cheese developed with high (> 800,000 cells mL-1) and low SCC levels (<200,000 cells mL-1). Seasonality did not affect fat content, casein, lactose, total solids, defatted dry extract and SCC, but lower protein levels than May and June were observed from July to September. Based on the SCC results, milk from refrigeration tanks was classified as low SCC and high SCC. The samples were used to obtain pasteurized milk and coalho... |
