Abstract In monogastric animals, tissue fatty acid profile directly reflects the fatty acid profile present in the animal’s diet. Inadequate ratio of fatty acids in food can lead to negative effects on human health. Conjugated linoleic acid (CLA) is a group of isomers of linoleic acid (C18:2), and its most interesting role is in the prevention of tumors, atherosclerosis and diabetes. CLA is found in ruminant meat and milk, and since pigs and poultry do not have the ability to synthesize CLA, it is possible to add them to animal feed with biotechnological solutions. The scientific public imposes modern parameters for determining the nutritional value of fatty acids, in which the AI – index of atherogenicity, TI – index of thrombogenicity and H/H - hypocholesterolemic/hypercholesterolemic ratio are distinguished. The aim of this study was to determine the effect CLA addition to the diet of non-ruminants on the lipid indices of certain categories of meat, from the aspect of consumer health needs. A significant influence of the correction of feed’s fatty acid composition on the lipid indices in food of animal origin was determined.

AbstractThis study quantified the fatty acid profile with emphasis on the stereo-specifically numbered (sn) 2 positional distribution in TAG and the composition of main phospholipids at different lactation stages. Colostrum milk (n 70), transitional milk (n 96) and mature milk (n 82) were obtained longitudinally from healthy lactating women in Shanghai. During lactation, total fatty acid content increased, with SFA dominating in fatty acid profile. A high ratio of n-6:n-3 PUFA was observed as 11:1 over lactation due to the abundance of linoleic acid in Chinese human milk. As the main SFA, palmitic acid showed absolute sn-2 selectivity, while oleic acid, linoleic acid and α-linolenic acid, the main unsaturated fatty acids, were primarily esterified at the sn-1 and sn-3 positions. Nervonic acid and C22 PUFA including DHA were more enriched in colostrum with an sn-2 positional preference. A total of three dominant phospholipids (phosphatidylethanolamine (PE), phosphatidylcholine (PC) and sphingomyelin (SM)) were analysed in the collected samples, and each showed a decline in amount over lactation. PC was the dominant compound followed by SM and PE. With prolonged breast-feeding time, percentage of PE in total phospholipids remained constant, but PC decreased, and SM increased. Results from this study indicated a lipid profile different from Western reports and may aid the development of future infant formula more suitable for Chinese babies.

Yerba Mate

Abstract The presence of secondary metabolites in the structure of natural antioxidants makes them an alternative for animal feed, which allows modifying the composition of the meat, thus contributing to people’s health. For this reason, the aim of the present study was to evaluate the effects of yerba mate extract (YME) on lamb feed as a natural antioxidant in the fatty acid profile and physical traits of meat of 36 lambs fed for 53 days, fed with corn silage and concentrate in the proportion 40:60, respectively. The treatments followed the randomized block design, with a control group without YME (0%) and three groups with 1, 2, and 4% of YME inclusion in the dry matter (DM). Samples were collected from the Longissimus thoracis (LT), muscle for quality analysis and composition. All data were analyzed using a MIXED model with orthogonal contrasts. We found that the inclusion of YME did not affect significantly the characteristics of the pH, total lipids and color general (P = 0.192), although the use of YME don’t affect the parameters normal in the meat. Nevertheless, the use of YME improved the value of b* (P = 0.004), showing a yellowness coloration in the meat of the lambs. Likewise, changed the proportion of branched-chain fatty acids (BCFA; P = 0.009) and the conjugated linoleic acid (CLA; P = 0.030) exhibited a diet effect for the group with 4% YME. This is revealing result, since these fatty acids have been associated with a decrease in cardiovascular diseases. Therefore, the addition of up to 4% YME improves the composition and general acceptance of lamb meat, recommended for use in animal feed.

Eight multiparous Holstein cows in mid lactation (average days in milking of 160 ± 40) were used in a replicated 4 by 4 Latin square design, each experimental period lasting 3 weeks, to determine the effects of whole cottonseed (WCS) treatment and dietary crude protein (CP) concentration on the profile of milk fatty acids. Each 3-week experimental period consisted of 2 weeks for ration adaptation followed by 1 week for data collection. The experimental diets consisted of: (1) Control (without WCS), 16% CP; (2) 20% WCS, 16% CP; (3) 20% WCS, 13% CP; and (4) 20% crushed WCS, 13% CP. Minerals and vitamin supplements were the same in all experimental diets. The WCS treatment led to increased DM intake, fat-corrected milk yield, fat concentration, proportion of long-chain fatty acids, unsaturated fatty acids and ratio of unsaturated to saturated fatty acids (P < 0.05). Decreased concentration of dietary CP from 16 to 13% (diet 2 compared with diet 3) led to a decrease in both milk yield and milk composition (P < 0.05). WCS crushed in diets with 13% CP (diet 4 compared with diet 3) increased (P < 0.05) the concentration of conjugated linoleic acid in milk fat. The results demonstrated that adding WCS to the diet of lactating cows improves both milk yield and milk fatty acid profile, particularly the proportion of conjugated linoleic acid.

Carbohydrate Digestion

Lipids are commonly used in ruminant diets to increase the energy density of the ration and increasingly to manipulate the fatty acid (FA) composition of the final product (meat or milk). However, lipids may have negative effects on rumen function and in particular on the extent of carbohydrate digestion, which is accompanied by alterations in volatile fatty acid proportions, towards less acetate and more propionate. These alternations are more pronounced for lipids high in polyunsaturated fatty acids particularly linolenic acid (18:3n-3; found in linseed). However, there is some evidence to suggest that the opposite is true for longer chain C20 FAs, found in fish oil (Doreau and Chilliard, 1996). This experiment has examined the impact of lipid sources differing in their FA composition (saturated compared polyunsaturated FA) on digestion of nutrients in the rumen and small intestine.

The influence of selenite (Se<sup>IV</sup>) or selenate (Se<sup>VI</sup>) added to ovine ruminal fluid containing linseed oil (LO) on the profile of fatty acids (FA), particularly conjugated linoleic acid (CLA) isomers, was investigated. The ruminal fluid was incubated in vitro at 39&deg;C under CO<sub>2</sub> either alone (the control fluid) or with LO (3.3 mg/ml) or with a combination of LO with either a low (0.167 &mu;g/ml) or high (1.67 &mu;g/ml) level of Se as Se<sup>IV</sup> or Se<sup>VI</sup>. LO added to ruminal fluids also provides an extra source of energy. The tubes with the examined fluids were removed after 0, 6, 12, 18, or 24 h of in vitro incubation and then analyzed to determine the FA levels. The lower and higher concentration of Se<sup>IV </sup>in the fluids with the LO revealed negligible effect on the concentration of the sum of the CLA isomers (&sum;CLA) in the fluid compared with the fluid with LO alone. The addition of a higher amount of Se<sup>IV</sup> to the fluid containing LO usually decreased the concentration of &sum;CLA compared with the fluid containing the lower concentration of Se<sup>IV</sup> and LO. The concentration of c9t11c15C18:3 (cLNA) in the fluids with LO, irrespective of the presence of extra Se, increased throughout the incubations, although the addition of Se<sup>IV </sup>or Se<sup>VI</sup> to the fluids containing LO numerically reduced the increase of the concentration of cLNA compared with the fluid with LO alone. The concentration sum of the C18:1 isomers (&Sigma;C18:1) in the control fluid numerically decreased throughout the incubations, while LO added to the fluid increased the concentration of &Sigma;C18:1 throughout the incubations. LO added to the fluid, irrespective of the presence of Se<sup>IV</sup> or Se<sup>VI</sup>, significantly increased the concentration of &Sigma;C18:1 compared with the control fluid and the fluids with Se<sup>IV </sup>or Se<sup>VI</sup>. The concentrations of C16:0 and C18:0 in the control fluid and the fluids containing Se<sup>IV</sup> or Se<sup>VI </sup>numerically increased throughout the incubations and were usually lower than in the fluids containing LO without or with Se<sup>IV </sup>or Se<sup>VI</sup>. The concentration of C18:3n-3 decreased throughout the incubation of the fluids containing LO, irrespective of the presence of Se<sup>IV </sup>or Se<sup>VI</sup>. LO added to the fluids, irrespective of the presence of Se<sup>IV</sup> or Se<sup>VI</sup>, increased the concentration of C18:2n-6 compared with the control fluid and the fluids with Se<sup>IV </sup>or Se<sup>VI</sup>. The higher concentration of Se<sup>IV</sup> or Se<sup>VI</sup> in the fluid with LO most efficiently increased the concentration of c5c8c11c14c17C20:5 compared with the control fluid or the fluids containing LO, irrespective of the presence of the lower concentration of Se<sup>IV</sup> or Se<sup>VI</sup>. LO added to the fluid, irrespective of the presence of Se<sup>IV </sup>or Se<sup>VI</sup>, increased the concentration of polyunsaturated FA compared with the control fluid or the fluids containing Se<sup>IV </sup>or Se<sup>VI</sup>. &nbsp; &nbsp;

Preliminary Study

Fatty acids from the omega-3 family are an important element of both human and animal diets. Their activity involves a range of functions for the functioning of a whole organism, and their presence in animal diets can be considered as a means for animal origin product enrichment for human benefit or as compounds profitable for an animal’s health status. The aim of this preliminary study was to compare the effect of supplements rich in omega-3 fatty acids (linseed oil, linseed oil ethyl esters, and fish oil) in rat feed on the fatty acid profile of their intramuscular and perimuscular fat. The results demonstrated beneficial changes in fatty acid profiles (a decrease in saturated acids, an increase in unsaturated ones, i.e., omega-3 acids share) of examined tissues in the case of all supplements however, particular attention should be paid to linseed oil ethyl esters, which significantly increased the content of all omega-3 acids. Supplementation of animal diet with linseed oil ethyl esters may be beneficial for both animals, as omega-3 fatty acids exhibit profitable properties related to an animal’s health status and productivity, and humans who consume such enriched products.

The effects of feeding diets with conjugated linoleic acid (CLA) to Astyanax altiparanae for different periods were investigated on carcasses’ fatty acid profile and nutritional quality. The trial was laid out in a complete randomized design with eight feeding periods (0, 7, 14, 21, 28, 35, 42, and 49 days) and four replicates. A total of 240 fish (3.4 ± 0.3 g) were distributed into four aquariums and fed with the diet containing 32% crude protein, 15 MJ kg-1 gross energy, and 2.5% of CLA. Feeding CLA diet for 49 days resulted in the higher deposition of CLA, CLA isomers, and docosahexaenoic acid (DHA). The isomer c9,t11 was highly deposited than the t10,c12. Polyunsaturated fatty acids (PUFA), n-3, and n-6 increased with feeding period, whereas saturated (SFA), monounsaturated, and medium-chain fatty acids decreased. PUFA/SFA ratio, DHA/EPA, EPA+DHA, and thrombogenicity index increased linearly. Whereas atherogenicity index reduced, hypocholesterolemic/hypercholesterolemic ratio increased in quadratic effects over feeding time. No difference was observed for the n-6/n-3 ratio. Feeding A. altiparanae with 2.5% of CLA for a minimum of 35 days improves the fatty acid profile and provides a commercial product with good nutritional quality and functional benefits.

ABSTRACT The present research aimed to determine the fatty acid profile in the seed oil of cagaita fruits cultivated in Goiânia, state of Goiás, in 2013 and 2014 harvests. The study was carried out with fruits produced by cagaita trees cultivated in the field of the School of Agronomy, Federal University of Goiás (EA/UFG), Goiânia, GO, where, in 1998, 440 cagaita seedlings from different municipalities in Goiás were planted. Fruits were collected from plants with 16 years of age in full production stage. Cagaita seeds show in their fatty acid profile mostly linoleic acid, oleic acid and palmitic acid. There was no variation in fatty acids content present in seeds between years 2013 and 2014, assuming that there are no external influences such as weather, foliar nutrients or soil, in the production of these oils
