The effects of fat source (0.7 kg of fatty acids from extruded soybeans or palmitic acid), of sodium bicarbonate (0.3 kg) plus straw (1 kg) and the interaction of these treatments on the content of conjugated linoleic acid (CLA) in the milk of dairy cows were examined. During nine weeks a group of 10 cows received a ration with palmitic acid and bicarbonate plus straw (ration PAB). During three...

This experiment was aimed to study the association between the DGAT1 K232A polymorphism and milk production traits and somatic cell score (SCS) in Iranian Holstein dairy cows. The records of 408 animals from five dairy herds were randomly identified and then genomic DNA was extracted from blood using the modified-salting method described by Miller. RFLP-PCR was performed to obtain all the polym...

The objective of this study was to determine the effects of feeding an increased amount of extruded flaxseed with high proportions of n-3 fatty acids (FA) to transition dairy cows on performance, energy balance, and FA composition in plasma, adipose tissue, and milk fat. Multiparous Israeli-Holstein dry cows (n = 44) at 256 d of pregnancy were assigned to 2 treatments: (1) control cows were fed...

The content of polychlorinated biphenyls was determined in human milk collected from four regions of Poland, as well as in cow’s milk and infant formulas. Significant statistical differences in PCB levels were determined in human milk depending on the region. The highest PCB mean concentration (0.351 mg.kg-1 milk fat) was determined in human milk from Gdańsk. An average of 0.218 mg PCB kg-1 mil...

The experiment was carried out on lactating Holstein Friesian cows with the objectives of evaluating the effect of stage of age, pregnancy, lactation, parity and on yield, and components (fat, protein, solid not fat and lactose) and pH of milk. Milk samples were directly collected from the teat and immediately analysed using milk. The result showed that lactation stage and pregnancy significant...

The importance of the plyunsaturated fatty acid in milk in the growth of nurslings needs no further mention. According to Bosworth et al.(1), arachidonic but no linoleic and linolenic acids are present in the polyunsaturated fatty acid of milk-fat. However, Hilditch et al.(2) reported that milk-fat contains linoleic acid at a level of 5%. Riemenschneider et al.(3) reported that the arachidonic ...

After receiving milk-based formula for one week, 16 preterm infants, weighing 1,300 to 1,800 gm, were fed two isocaloric formulas containing either medium-chain or long-chain triglycerides for 15 days; the alternate formula was given for a second period of identical duration. While receiving MCT, the infants had greater (P smaller than 0.01) percent fat absorption (83.4 leads to 97.1%) and weig...

Wiking, L. 2005. Milk Fat Globule Stability Lipolysis with Special Reference to Automatic Milking Systems. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-7048-X The implementation of automatic milking systems (AMS) initially caused a lowering of the milk quality regarding free fatty acids (FFA). A high level of FFA increases the risk of rancid flavour in dairy products. The objective of the...

Different technologically treated Italian milks (whole and semi-skimmed ultra-high temperature (UHT), pasteurized and microfiltered milk), collected from 2009 to 2012, were evaluated for nutritional and technological properties. No significant differences in calcium and sodium were detected (p > 0.05), while significant differences were observed concerning phosphorus content, between whole and ...
