Conjugated Linoleic Acid: A Milk Fatty Acid with Unique Health Benefit Properties Kathirvelan Chinnadurai and Amrish Tyagi Tamilnadu Veterinary and Animal Sciences University India 1. Introduction
01-10-2006· To evaluate milk production and milk fatty acid (FA) composition and conjugated linoleic acid (CLA) content, 75 Sicilo-Sarde ewes were used on three dietary treatments during 89 days. Two groups were conducted on rotational grazing in separate pastures of green barley grass (GB group) or perennial ryegrass (RG group) and receiving daily 300 g of concentrate/ewe.
Conjugated linoleic acid (CLA) isomers effect an impressive range of biological processes including the ability to inhibit milk fatty acid synthesis. Although this has been demonstrated in several mammals, research has been most extensive with dairy cows.
Conjugated linoleic acid: A mixture of bio- active fatty acids in milk fat of ruminants Variation in CLA content of ruminants has been associated with several factors such as stage of lactation, parity [27], and breed [28 - 29].However, diet is the most important factor influencing CLA concentration [17, 29-30].
Conjugated linoleic acids represent a mixture of posi-tional and geometric isomers of octadecadienoic acid with conjugated double bonds. The presence of fatty acids with conjugated double bonds was first demonstrated in food products derived from ruminants by Booth et al. (1935) working with milk fat from cows turned out to spring pasture.

Conjugated linoleic acid was 5.3, 8.6, 6.8, and 8.9 mg/g of milk fatty acids in the control, fish meal, monensin, and fish meal plus monensin treatments, respectively. In Experiment 4, cows were fed either finely chopped alfalfa hay (Treatment 1), or coarsely chopped alfalfa hay (Treatment 2) in a 50% forage and 50% grain diet, or 66.6% grass hay and 33.4% grain (Treatment 3), or 98.2% grass ...
The major TFA in milk, butter, and beef fat is trans vaccenic acid (11t-18:1). A specific fatty acid with suggested anticarcinogenic properties is conjugated linoleic acid (CLA), which also is pri- marily found in dairy products and meat from ruminants and is hardly present in vegetable products.
Conjugated Linoleic Acid (CLA) refers to a group of naturally occurring isomers of linoleic acid present in ruminant fats and dairy products. Unlike industrial trans fatty acids, trans CLA may be of great potential benefit to human health. CLA isomers are produced from the biohydrogenation of linoleic acid by rumen bacteria of animals.
BACKGROUND: Conjugated linoleic acid (CLA) is a special fatty acid in dairy products with unique antioxidant and anti-cancerous effects. Kefir, a milk product, comprises normalized homogenized cow's milk, the fructose and lactulose syrup as well as a symbiotic …

08-06-2009· The present work shows the fatty acid composition and chemical characteristics of two fresh cheeses manufactured with cow and goat milk. Animals were fed on natural pasture during summer and spring seasons. It is known that pasture increases conjugated linoleic acid (CLA) concentration in milk fat, and the content in cheese is directly related ...
01-08-1999· Conjugated linoleic acids (CLA) 5 represent a mixture of positional and geometric isomers of octadecadienoic acid with conjugated double bonds. CLA have been demonstrated to have a range of positive health effects in experimental models. These include suppression of carcinogenesis (Belury 1995, Ip et al. 1994), antiobesity effect (Park et al. 1997), modulation of the immune system (Cook et …
Conjugated Linoleic Acid (CLA) refers to a mi xture of positional and geometric isomers of linoleic acid (cis-9, cis-12, C18:2) with two conjugated double bonds at various carbon positions in the fatty acid chain. It is formed as an intermediate during the biohydrogenation of linoleic acid by linoleic acid isomerase from the rumen bacteria
01-05-2007· Under certain dietary situations, rumen biohydrogenation results in the production of unique fatty acids that inhibit milk fat synthesis. The first of these to be identified was trans-10, cis-12 conjugated linoleic acid (CLA), but others are postulated to contribute to diet-induced milk fat depression (MFD).Our objective was to examine the potential role of trans-9, cis-11 CLA in the ...
Conjugated linoleic acid (CLA) is a fatty acid found in milk fat that has a specific chemical arrangement and unique health benefits. CLA is an 18 carbon fatty acid with 2 double bonds that are conjugated, meaning that the double bonds are on adjacent carbon atoms in the fatty acid chain, rather than being separated by one or more carbons.
12-09-2011· Conjugated linoleic acid is unique; unlike the most naturally occurring anticarcinogenic substances found mainly in plants, it is present in food from animal …
Sources of conjugated linoleic acid: Many of the functional ingredients of milk and milk products are good for heart and posses good qualities of human health as a whole (Midau et al., 2010).The meat and milk of grass-fed ruminants offers the richest source of natural CLA (Singh et al., 2009; Foda et al., 2009).Whole milk, cream, butter, cheese and whole milk yogurt from grass-fed animals are ...
