This study aimed to determine the effect of milk fatty acid composition, breed, and pregnancy status on total fat in dairy cows. The was conducted with a 400 samples collected form healthy Holstein Simmental Milk were for analysis. To investigate effects acids, breed fat, multiple linear regression analysis performed. As result analysis, status, C11:0, C14:0, C18:0, C18:1 ω9 C18:3 ω6 found be s...

The aim of the present work was to study, in dairy goats, the effect of replacing 35% of concentrate in the diet with feed blocks including tomato fruits wastes on CH4 emission, milk yield and fatty acid and amino acid profiles. Eight Granadina goats (39.6 ± 1.89 kg BW) in the middle of the third lactation were used, and a two-periods trial was carried out following a crossover design. In each ...

Dietary lipids are key for infants to not only meet their high energy needs but also fulfill numerous metabolic and physiological functions critical to their growth, development, and health. The lipid composition of breast milk varies during lactation and according to the mother's diet, whereas the lipid composition of infant formulae varies according to the blend of different fat sources. This...

1. The effects in the cow of intraruminal infusions of acetic acid, propionic acid or butyric acid on the secretion of the component fatty acids of the milk fat, and of these acids and of lactic acid on the composition of the blood plasma of the jugular vein, have been studied. 2. The infusion of acetic acid or butyric acid increased the yield of the C(4)-C(16) acids of milk fat but decreased t...

Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...

The importance of the plyunsaturated fatty acid in milk in the growth of nurslings needs no further mention. According to Bosworth et al.(1), arachidonic but no linoleic and linolenic acids are present in the polyunsaturated fatty acid of milk-fat. However, Hilditch et al.(2) reported that milk-fat contains linoleic acid at a level of 5%. Riemenschneider et al.(3) reported that the arachidonic ...

Dietary changes alter dairy cow milk fat concentration (MFC) and yield (MFY) through modifications in the supply of nutrients, which act as precursors or inhibitors of mammary fat synthesis. The current models used to formulate dairy cow diets cannot predict changes in milk fat. The knowledge of the effects of the nutrients on milk fat would help to progress toward this prediction. To this end,...

BACKGROUND: Previous studies showed differences in fatty acid (FA) and antioxidant profiles between organic and conventional milk. However, they did not (a) investigate seasonal differences, (b) include non-organic, lowinput systems or (c) compare individual carotenoids, stereoisomers of α-tocopherol or isomers of conjugated linoleic acid. This survey-based study compares milk from three produc...

Milk is often seen as a potential promotor of atherosclerosis and coronary heart disease because it is a source of cholesterol and saturated fatty acids. But there are several studies indicating that milk and milk products may not affect adversely blood lipids as would be predicted from its fat content and fat composition. There are even factors in milk and milk products which may actively prot...

This study was carried out to determine the physicochemical properties and fatty acid composition of milk samples collected from different originated Anatolian water buffaloes living in same farm. The fat amounts were ranged between 5.24 8.67%. acids with highest ratios buffalo belonged C16:0 (palmitic acid), C18:1 (oleic C18:0 (stearic acid) C14:0 (myristic acid). Saturated (SFA) (62.6 67.3 %)...
