The aim of this research was to investigate the changes in milk yield and its composition, fatty acid profile and peroxisome proliferator-activated receptors gamma (PPARG) gene expression in adipose tissue of Iranian Holstein cattle in response to feeding isonitrogenous and isocaloric diets but formulated based on different oilseeds (soybean or canola seeds). Twenty cows were tested ra...

Milk quality has been an issue of public health concern and changes occur in milk composition with the changing physiological and management states. An experiment was conducted to investigate changes in milk yield and fatty acids profile with advancing age and lactation stage in dairy buffaloes. A total of 12 multiparous lactating dairy buffaloes were divided into two groups younger (1-4 lactat...

seasonal variation of fatty acids composition of milk and various milk products have been subjected to many investigations.however ,most of the researches are concerned with a single product and apparantly there is no inforation about the extent and the factors which contribute to changes in fatty acids composition of lipids in the process of ghee-making by the  traditional methods.thus compara...

The addition of vegetable oils to the diets of dairy goats is an alternative to supplemental feeding during the dry period and improves the lipid profile of milk and by-products. Cheeses were produced using milk from cross bred goats (Saanen×Alpina) fed diets enriched with 4% vegetable oil (faveleira, sesame or castor), the fatty acid profile of cheeses was studied. Supplementation with vegetab...

The aim of this study was to evaluate the effect of fat supplementation for enhancing milk conjugated linoleic acid (CLA) in early lactation without affecting ruminal fermentation. 24 Holstein dairy cows were assigned to a completely randomized design employing a 2 × 4 factorial arrangement. Factors were particle size (15 and 25 mm) and two different sources of alfalfa supplemented with and wit...

fatty acids play important roles in biological systems and the newborns fatty acids requirements are covered only by the milk. it is of particular interest to qualify the content of the fatty acids in the milk. this study was performed to determine the levels of some fatty acids in the infant formulas and also to describe a method without derivatization for the fatty acids analysis and applying...

The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...

Lipid supplements (oilseeds vegetables) are included in ruminant diet to increase its energy density and improve fatty acid composition of milk and consequently of fresh cheese. Milk and cheeses were evaluated from crossbred Holstein × Zebu, fed diets enriched with 0%, 25%, 50%, and 75% inclusion levels of palm kernel cake in concentrated supplement, which were supplied daily (3.0 kg). Milk and...

The aim of this experiment was to determine the effects of conjugated linoleic acid (CLA) on milk production and composition, and milk fatty acid profile of dairy Holstein cows. Three lactating Holstein cows (203 ± 9 DIM; mean ± SD) fitted with rumen fistula were used in a 3 × 3 Latin square experiment with 21-d periods, including a 14-d adaptation period followed by a 7-d sampling period. Trea...

BACKGROUND Human milk is the optimal nutrition for infants. When breastfeeding is not possible, supplementation of infant formula with long chain polyunsaturated fatty acids appears to promote neurodevelopmental outcome and visual function. Plant oils, that are the only source of fat in most of infant formulas, do not contain specific fatty acids that are present in human and cow milk and do no...
