| This study aimed to evaluate milk composition and metabolic profile of Holstein cows at different calving orders in the beginning, middle, and end of lactation. One hundred ten Holstein cows were housed in a free stall system receiving the same diet and were grouped according to calving order (first, second, third, and fourth calving) and days in milk (DIM): early (1-90 DIM), middle (91-180 DIM), and end of lactation (over 181 DIM) for comparing milk yield, milk composition, and blood metabolic profile between the calving orders within the same lactation period. These parameters were also evaluated between lactation periods of the cows in different calving orders. The calving order, in any lactation stage, had no influence on milk yield per day and blood... |

| The concentrations of the six major sialyl oligosaccharides found in the milk of 24 Japanese women were determined using reverse phase high performance liquid chromatography of the 3-methyl-1-phenyl-5- pyrazolone derivatives of the oligosaccharides. The milk was collected at 4, 10, 30 and 100 days postpartum. The concentrations of all six oligosaccharides decreased during the course of lactation. The concentrations of 6'-sialyllactose, sialyllacto-N-tetraose b and disialyllacto-N-tetraose decreased only after 10 days postpartum, whereas those of sialyllacto-N-tetraose a and sialyllacto-N-neotetraose c as well as 3'-sialyllactose decreased from 4 days postpartum. Large differences were observed between present data and those previously reported for Italian... |

| 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... |
