Forty-eight Holstein cows (16 primiparous) were fed alfalfa silage-based TMR containing 18% CP with 33 or 36% of the CP as undegraded intake protein and with 0 or 2.8% supplemental fat (DM basis). Expeller soybean meal replaced solvent soybean meal to vary undegraded intake protein, and sodium alginate-treated tallow was used as the fat source. A standard diet containing solvent soybean meal wi...

The study was undertaken to evaluate some chemical parameters of powder milk available in Mymensingh town. Powder milk samples of six different brands namely Kwality, NIDO, Diploma, Anchor, Farmland & Starship were collected from local market. Powder samples were analyzed to know the chemical (P, acidity, fat, protein, lactose, ash, moisture, solids-not-fat, total solids) characteristics. P, ac...

Milk fat yield affects the price received for milk by dairy farmers, and given the rising feed costs, maximizing diet digestibility is critical for the economical viability of dairy farms. Although feeding animal-vegetable fat or coconut oil to dairy cows can increase energy intake, they sometimes cause milk fat depression (MFD). Feeding monensin has been found to increase feed efficiency and m...

To determine whether insulin exerts an effect on milk fat yield through the direct regulation of milk fat synthesis in the mammary gland, the hyperinsulinemic-euglycemic clamp procedure was performed in lactating goats in the present study. The effects of the hyperinsulinemic-euglycemic clamp on milk yield, milk composition, milk fatty acid yield and the expression levels of mRNAs of milk fat s...

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...

Title of Document: REGULATION OF MILK FAT SYNTHESIS BY DIETARY FATTY ACIDS ANIL KUMAR G. KADEGOWDA PhD. 2008 Directed By: Professor, Dr. RICHARD ERDMAN, Dept. of Animal and AvianSciences, UMCP. The objectives of this thesis research were to determine the molecular mechanisms by which dietary fatty acids (FA) regulate lipogenic gene expression and milk fat synthesis. Principal component and mult...

The objective of this paper was to determine the opportunities of improving milk productivity and altering the milk composition through nutritional interventions. The increase in the nutraceutical value of milk is expected through dietary modifications of the animal. Feeding high concentrate diets combined with dietary fat can be used to modify the FA profile of milk, without negative effect on...

Membrane events during milk fat secretion were analyzed by freeze-fracture of the rat mammary gland. Two modes of milk fat secretion were observed: extrusion of fat droplets surrounded by a portion of the apical plasma membrane of the alveolar epithelial cells and, less frequently, release into the alveolar lumen of fat droplets contained in intracytoplasmic vacuoles. The extrusion process cons...

Background Ingesting a post-workout beverage containing carbohydrate and high quality protein has been shown to favorably improve body composition and exercise performance. Chocolate milk supplies both carbohydrate and high quality proteins (casein and whey). For this reason, chocolate milk has become an increasingly popular sports nutrition beverage. To date, no one has investigated the differ...
