The present experiment aimed to evaluate the effect of HMBi on the production performance and metabolism in dairy cows. Thirty multiparous Holstein dairy cows under similar conditions were randomly assigned to three dietary treatments; i) Control, a basal diet; ii) T1, a basal diet plus HMBi (0 g prepartum and 18 g postpartum); and iii) T2, a basal diet plus HMBi (10 g prepartum and 18 g postpa...

During secretion of milk fat globules, triacylglycerol (TAG) droplets are enveloped by a phospholipid (PL) trilayer. Globule size has been found to be related to polar lipid composition and fat content, and milk fat content and fatty acid composition have been associated with the diacylglycerol acyltransferase 1 (DGAT1) K232A polymorphism; however, the association between the DGAT1 polymorphism...

this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

Human milk is the ideal food to nourish newborn babies; it contains important nutrients: proteins, carbohydrates, fat, vitamins and minerals, which are needed to provide agood health to the infants. Milk fat provides about 50% of energy to infants and its fatty acids are essential for brain and retina development. Therefore, analysis of the lipid fraction of human milk is an important task, esp...

In this study, it was aimed to comparison the physicochemical properties and acceptability of different milk product including full and low fat milk and flavored milk such as chocolate, coffee and bananas milk. According to the result of current research the fat content in milk didn’t affect on the other nutrient component of milk such as protein, calcium and phosphorus also addition of flavori...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

The current cattle selection program for dairy cattle in the Walloon region of Belgium does not consider the relative content of the different fatty acids (FA) in milk. However, interest by the local dairy industry in differentiated milk products is increasing. Therefore, farmers may be interested in selecting their animals based on the fat composition. The aim of this study was to evaluate the...

OBJECTIVE To determine, by the creamatocrit measurement, the effect on the fat content of raw and pasteurized donor milk of freezing during 3 months at -20 °C. METHODS The evolution of the creamatocrit measurement (following Lucas technique) on frozen (-20 °C), raw and pasteurized human milk, was analyzed during 3 months. RESULTS The fat content of raw milk (n=44) was 3.19 g/dl at the begin...

OBJECTIVE To determine vitamin A (retinol) and fat concentrations in breast milk during early lactation. METHODS Healthy lactating women (n 88) aged between 18 and 35 years were randomly selected for the study from urban, semi-urban, rural and estate (plantation) sectors of Galle District. Their anthropometry was recorded; breast milk samples were collected from the right breast one hour afte...

In this study, modified starch was used as a fat replacer in the milk. The fat replacer was manufactured from modified starch such as pre-gelatinized and cross–linked starches. Modified starches were manufactured by hydrochloric acid and citric acid treatments from potato and wheat and were added to skim milk at concentrations of 0.15%, 0.30% and 0.45%. Viscosity, total solid, fat content, titr...
