The milk fat globule membrane (MFGM), which surrounds and stabilizes the fat globules, is released in buttermilk during cream churning. MFGM has many health benefits due to its composition rich in phospholipids and membrane proteins. Many techniques have been tried to separate the MFGM from the remaining milk solids non-fat, but they are challenging to carry out at an industrial scale. This research proposes a new approach to separating MFGM from buttermilk. This paper assessed the efficacy of hydroxyapatite (HA) cristal in interacting with MFGM isolates obtained from either raw or pasteurized cream. Different HA to MFGM ratios were used (10:1 and 20:1) to determine the impact of HA concentration on the adsorption. The results showed a very high affinity of the MFGM for HA and suggested the potential for its separation from buttermilk to improve its valorization.

A cross-sectional study on 156 smallholder dairy farms in Rwanda was carried out to assess the association between farm management practices and milk yield and quality. A pre-tested questionnaire was used to collect data on cow characteristics and farm management practices. Milk yield was recorded at household level, milk composition was monitored using a Lactoscan device (Milk Analyzer).

The and isomers of conjugated linoleic acid (CLA) are associated with anticancer and lipolytic effects in tissues, respectively, but in lactating cows, the latter isomer reduces the milk fat concentration, a detrimental aspect for the dairy industry, as it reduces the yield of milk derivatives. Therefore, the objective of this study was to evaluate the effect of providing protected palmitic acid (PA) to grazing lactating Holstein cows supplemented with soybean oil as a source of conjugated linoleic acid, on milk production, fat concentration and mitigation of milk fat depression. Nine multiparous Holstein cows were used, distributed in three groups of three cows each, with initial means of days in milk, live weight, milk production, and number of calvings: 124 ± 16 days, 494 ± 53 kg, 20.

Currently, the identification of valuable candidate genes affecting milk fat synthesis in dairy cows is still limited, and the specific regulatory mechanism is still unknown. In this study, we used primary bovine mammary epithelial cells(BMECs)as a model and utilized overexpression and knockdown techniques for the PI4K2A gene to investigate the specific mechanisms by which it regulates lipid metabolism in BMECs. We studied whether PI4K2A regulates the inhibition of trans-10, cis-12 conjugated linoleic acid (t10,c12-CLA) on lipid synthesis in BMECs.

Present research focused on biotransformation of paneer whey into a functional fermented product using kefir culture. Out of 9 formulations (S-1 to S-9) tried; S-8, obtained by fermenting FOS (1%) supplemented paneer whey and adding 8% refined sugar, was identified as the most acceptable product. Nutritional analysis revealed the following as per 100 g of product: 44.
