| The objective of the present work was to evaluate the physical-chemical characteristics (density, pH, acidity, fat, protein, lactose and total of solids contents) and milk fatty acids composition (C: 4 to C: 20) in response to roughage sources (alfalfa hay T1; oat hay T2 and maize silage T3). Nine Saanen lactating goats were used, in a triple Youden square design (3 animals x 2 periods). There was no treatment effects in the physical-chemical variables in the univariate analyses; by multivariate analyses three distinct patterns of fatty acids could be defined: milk with greater quantity of short chain fatty acids and acids C17:1omega7 e C18:2omega6 (T1); milk with equivalent amounts of short, medium and long chain fatty acids (T2); and milk with greater... |

| 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. |

| This study aimed to evaluate the effect of corn silage (CS) replacement by cassava's foliage silage (CFS) on the production and quality of milk. Twelve lactating dairy cows were used in a randomized block experimental design with four treatments and three repetitions per block. CS was replaced by CFS at the levels of 0, 20, 40, and 60%. The replacement of CS by different levels of CFS had very low effect on the variables studied. Milk density decreased when the replacement level was increased. Fatty acids 4:0 and 6:0 presented a quadratic behavior, while fat acids 8:0, 10:0, and 15:0 presented a linear behavior as their concentrations fell when CFS diet content was increased. The CS replacement by 20% until 60% CFS resulted a significant decrease in the... |

| 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 effects of inactive dry yeast (Saccharomyces cerevisiae) from sugar cane were studied in 18 primiparus Saanen dairy goats (51.07±1.43) on dry matter intake and digestibility, milk production and quality. Animals were distributed in a completely randomized design during 90 days (from day 60 of milking). Diets were composed of soybean meal; soybean meal + dry yeast; or dry yeast, as protein sources, and ground corn, mineral supplement and corn silage (40%). Animals fed the dry yeast diet showed lower intake of dry matter (DM), organic matter (OM), crude protein, ether extract and neutral detergent fiber. Diets did not influence milk yield; however the milk production efficiency (kg of milk produced/kg of crude protein ingested) was better in goats fed... |

| 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... |

| 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... |

| The objective of the present study was to characterize the food sources, as well as the composition and quality of milk obtained from household farms of western Paraná State (Brazil) with and without technical assistance during the different seasons. For such, 24 properties were selected, 12 of which only received assistance and technical support. Four milk samples were taken (summer, autumn, winter and spring) to assess the physicochemical composition, somatic cell count and total bacterial count and feed supplied to the animals to assess the chemical composition (crude protein, ash, dry matter and neutral detergent fiber). The data were analyzed in a completely randomized design with a 2 × 4 factorial arrangement; the first factor was the presence and... |

| 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... |
