introduction: cholesterol and fatty acids are two important components of the lipids. various fatty acids have different effects on plasma lipoproteins. consumption of saturated fatty acids tends to increase total plasma and ldl cholesterol levels. while  polyunsaturated fatty acids reduce both ldl and hdl cholesterol, edible oil rich in monounsaturated fatty acid (mufa) however, tend to lower ...

The objective of this study was to compare milk protein, amino acid and fatty acid content and composition among two breeds of river buffalo (Murrah and Nili-Ravi), and their hybrid F1 and F2 (crossbreeding with local swamp buffalo). The protein and fat content in milk from crossbreed F1 and F2 were significant higher than that of river buffalo, but the milk yield was still lower than Nili-Ravi...

The objective of the present study was to determine the effect of substitution of corn grain with dried citrus pulp (DCP) on milk composition, fatty acids profiles and blood metabolites in Holstein dairy cows. These parameters were measured in a replicated 4 × 4 latin square design experiment using eight Holstein cows. Each experimental period lasted 4 weeks. The four treatments were: control (...

background and objectives: in this study, the proteolysis and lipolysis of poosti cheese produced from raw sheep milk in mountainous eastern regions of iran were investigated during 90 days of ripening. materials and methods: sodium dodecyl sulfate polyacrylamide gel electrophoresis for proteolysis (sds-page) and gas chromatography (gc) for free fatty acids (ffas) were applied to investigate th...

The predominant fatty acids in milk are the long-chain fatty acids myristic, palmitic and stearic. These saturated fatty acids account for 75% of the total fatty acids, with a further 21% occurring as monounsaturated fatty acids of which the most prevalent is oleic acid. Only 4 g/100 g of the milk fatty acids are polyunsaturated, occurring mainly as linoleic and linolenic acids. All milk fatty ...

this study was conducted to evaluate the effect of supplementing diets of milking cows monensin supplementation alone or in combination with methafix (a commercial product containing malate and fumarate) on nutrient digestibility, milk production and composition and milk fatty acids profile. using four multiparous holstein milking cows (657± 12 kg of live weight; 133 ± 41days in milk) in a lati...

The aim of the present study was to evaluate effects dietary ricinoleic acid from castor oil on milk yield, composition, fatty profile and haemato-biochemical in lactating Kankrej cows. Twenty cows were assigned following groups: control (CON), basal diet without any additive treatment (RAS), with 2 g/animal/day oil. Dietary had no (P>0.05) effect dry matter intake feed efficiency. Milk yiel...

  In this study changes in fatty acids profile during frozen storage at -18°C of Cobia (Rachycentron canadum), caught from the Persian Gulf (Bandar Abbas) were studied. Changes in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), EPA+DHA/C16, n-3 PUFA/n-6 PUFA (n-3/n-6) and polyunsaturated fatty acids /saturated fatty acids (PUFA/SFA) were i...

  In this study changes in fatty acids profile during frozen storage at -18°C of Cobia (Rachycentron canadum), caught from the Persian Gulf (Bandar Abbas) were studied.

The aim of this research was to study the potential for selection of cows with a higher nutritional quality of milk fat by studying the differences in fatty acid profiles within and across the following breeds: Dual Purpose Belgian Blue, Holstein-Friesian, Jersey, Montbeliarde, and non-Holstein Meuse-Rhine-Yssel type Red and White. Six hundred milk samples from 275 animals were taken from 7 her...
