Cold storage is a well-known strategy to limit concerns about seasonality for sheep dairy productions. Th e aim of this study was to investigate the eff ect of long-term freezing on milk renneting properties from the Sarda sheep, an autochthonous breed from Italy. Two-hundred milk samples from 50 pluriparous Sarda ewes were collected at monthly intervals throughout the lactation from April to J...

During a 12-mo longitudinal study, bulk-tank milk was collected each month from organic (n = 17) and conventional (n = 19) dairy farms in the United Kingdom. All milk samples were analyzed for fatty acid (FA) content, with the farming system type, herd production level, and nutritional factors affecting the FA composition investigated by use of mixed model analyses. Models were constructed for ...

The aim of this study was to determine human prenatal and postnatal exposures to polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), hydroxylated metabolites of PCBs (polychlorobiphenylols; OH-PCBs), and pentachlorophenol (PCP). The median PBDE fresh-weight concentrations in maternal and cord blood plasma and in breast milk were 24, 4.3, and 75 pg/g, respectively. The PCB ...

Milk quality criteria and limits for somatic cell count (SCC) established in many countries make it difficult to maintain SCC of bulk tank goat milk below the threshold, due to non infection factors linked to goat physiology. The aim of this study was to objectively verify the effects of SCC on fresh caprine milk cheese. Somatic cells were recovered from pooled healthy goat milk, and added to l...

This paper aimed to evaluate the changes in thermal stability of goat milk, cow milk and homogenized under different pH conditions. The results showed that was type B were positively correlated with value. But A most stable fresh 6.9, while it 6.7 for milk. Compared acidification stronger due heat. Therefore, process production, germicidal heating conditions two sources should be determined acc...

THE milk-fats from goats and sheep are used, although only to a small extent, as substitutes for those of cows and buffaloes in India. The component fatty acids and glycerides of these two fats have been studied by methods recently developed [Hilditch et al., 1929; 1930; 1931] in the case of cow butter-fats, in order to compare their composition with those of the latter and, in certain respects...

the objective fllowed in the present study was to evaluate the effects of different milkingfrequencies on milk production and on blood metabolites in holstein cows. sixty-six fresh holsteincows were allocated to two treatments namely: 4 (4x) vs. 6 times (6x) of daily milking, during the first3 months of lactation, and then switching on to a three times of daily milking until end of the lactatio...

Samples of maternal and foetal blood and of human milk, cow's milk, and dried cow's milk have been analysed for cobalamins by chromatography and bioautography. Plasma cobalamins in late pregnancy and after delivery differed quantitatively from those in healthy non-pregnant women. Differences in the proportions of plasma cobalamins were also observed between mothers and their newborn infants. Th...

2010 Society of Dairy Technology Volatile compounds in skim milk and nonstandardised milk subjected to instant infusion pasteurisation at 80 C, 100 C and 120 C were compared with raw milk, high temperature short time pasteurised milk and milk pasteurised at 85 C ⁄30 s. The composition of volatile compounds differed between infusion pasteurisation treated samples and the reference pasteurisation...
