Objective. The objective of the study was to determine the composition of fatty acids in milk of Creole goats in an extensive production system in an arid region of the peninsula of Baja California and compare it to two seasons of the year (rainy and dry). Materials and methods. Sampling was conducted during the dry season (June) and after the rainy season (December) in the municipality of Como...
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 There is growing interest in the fatty acid composition of breast milk and substitute formulas used to replace or complement infant breastfeeding. AIM The aims of this study were to assess the impact of two follow-up infant formulas based on cow milk fat, vegetable oils and different docosahexaenoic (DHA) and arachidonic (ARA) acid content on red blood cell membrane fatty acid comp...
Smen is a milk fat isolated by ‘boiling-off’ water. Milk fat was first converted into butter and then into smen. Smen product is utilized for culinary cooking and frying of different food. Smen has better shelf-life than other indigenous dairy products due to its lower moisture content. However, it undergoes deterioration (lipolysis and oxidation of milk fat) causes flavor impairment, lowers nu...
I. Changing cows from a diet with low hay and high flaked maize content, which depressed milk fat secretion, to a high-roughage diet resulted in increased milk fat secretion and in changes in the pattern of rumen fermentation and in the composition of the blood plasma. 2. During the 1st week following the change in diet the proportions of propionic and valeric acids in the rumen decreased and t...
BACKGROUND Few studies in recent years have demonstrated the effect of maternal diet on fatty acid composition of human milk. METHODS Fourteen free-living lactating women participated in a cross-over dietary intervention study, consuming a low fat diet (17.6% of energy as fat, 14.4% of energy as protein, 68.0% of energy as carbohydrate) and a high fat diet (40.3% of energy as fat, 14.4% of en...
This study aimed to evaluate the effects of length of chop of corn silage and forage:concentrate ratio (F:C) on performance and milk fatty acid profiles in dairy cows supplemented with flaxseed. Our hypothesis was that decreasing forage particle length and F:C ratio would increase unsaturated fatty acid flow to the small intestine and subsequent transfer of these unsaturated fatty acids into mi...
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...
