“…The current study shows that incorporation of LA into body fat of the goat kids was dose‐dependent, which corroborates earlier observations that LA was deposited in adipose tissue in a linear, dose‐dependent fashion (Yeom et al., 2002). The increase in the LA content of whole body fat was associated with a decrease in the content of fatty acids with a chain length of 16 carbon atoms or lower, which is in agreement with previous results (Yeom et al., 2002). This inverse relationship between LA and the shorter fatty acids may relate to either experimental design or to metabolism.…”

“…The milk replacers and carcass samples were subjected to dry matter (DM), total N and ash analysis as described previously by Xu and colleagues (2000). The lipids in the carcasses and milk replacers were extracted with chloroform–methanol (2 : 1, v/v ; Folch et al., 1957) and the fatty acid compositions were determined as reported previously by Yeom and colleagues (2002). Energy contents of milk replacers and that of weight gain were calculated (see footnote of Tables 1, 3 and 4).…”

“…In various animal species, including young ruminants fed a milk replacer, the relative percentage of linoleic acid (LA) (C18:2n‐6) in subcutaneous adipose tissue reflects the intake of this fatty acid (Veen, 1972; Mir et al., 2000; Yeom et al., 2002; Bavelaar and Beynen, 2003; Nguyen et al., 2003). However, the amount of fat in the body may also be influenced by LA intake.…”

Twenty, 1-2-day-old goat kids were used in a feeding trial to investigate the effect of linoleic acid (LA) (C18:2n-6) intake on weight gain and carcass composition. Eight animals were selected randomly and killed at the start of the trial to determine initial body composition. The other animals were assigned to the three dietary treatments and were fed milk replacers with varying LA concentrations (low: 5.5%; medium: 11.2% and high: 17.1% LA of total fatty acids) for 5 weeks. There was no systematic effect of LA intake on body composition. The average retentions of fat, protein, ash and energy were 46.3%, 61.2%, 42.2% and 37.4% respectively. Increased intakes of LA caused a significant increase in LA content of the carcass and of the weight gain, whereas there was a simultaneous decrease in fatty acids with 16 carbon atoms or less. The incorporation of LA into carcass was directly related to intake, but the percentage retention of LA remained constant. The data indicate that in goat kids the intake of extra LA raises the amount of LA in carcass but does not affect the total fat content.

“…The C18:2 n-6, C18:3 n-3 and total PUFA ratios were similar to those reported in other goat studies (Banskalieva et al, 2000;Mahgoub et al, 2002;Todaro et al, 2004;Bas et al, 2005;Werdi Pratiwi et al, 2007). Nevertheless, these proportions were lower than those reported in other studies (Yeom et al, 2002;Nudda et al, 2008), likely due to the higher concentration of C18:2 n-6 and C18:3 n-3 FA in the supplemented feed to the dams.…”

Interest in the preservation of autochthonous breeds such as the Payoya goat (dairy breed), raised using extensive or semi-extensive grazing, has also recently increased among Spanish farmers. A study of the possibilities of transformation to organic production needs to analyze the quality of their products, specially the suckled kids. The objective of this study was to evaluate the fatty acid (FA) composition of Payoya goat kids under organic and conventional grazing–based management system. Forty-eight goat kids were selected (12 males and 12 females from each management system). The FA profile was determined in the Longissimus thoracis muscle, kidney and pelvic fat. Few gender differences were observed in the muscle and in the fat depots. The ratios of C14:0, C18:1 trans-11-(VA), and several n-3 FA were higher in organic kid meat than in conventionally reared kid meat. Conventional kid fat depots have presented higher percentage of conjugated linoleic acid (CLA), lower CLA desaturase index, lower percentage of n-3 polyunsaturated fatty-acid (PUFA) and, consequently, higher n6:n3 PUFA ratio than organic kids. In conclusion, significant differences were found only in some FA percentages of muscle and adipose tissues of suckling kids raised in organic and conventional livestock production systems, probably due because the dams, in both experimental farms, were raised with similar semi-extensive system based on the grazing of natural pastures. Due to this reason, conventional grazing–based management farms could easily be transformed into organic production facilities.

“…This might be related to the short experimental (Ruckebusch et al, 1991). The fatty acid composition of erythrocytes can be affected by high intakes of polyunsaturated fatty acids, as shown in rats (Periago et al, 1990), calves (Sklan et al, 1972) and goat kids (Yeom et al, 2002). Feeding extra linoleic acid (C18:2 n-6) in the form of soyabean oil caused a marked increase in the concentration of this fatty acid in the plasma of goats (Yeom et al, 2003).…”

An experiment was conducted to study the effects of extruded cotton seed (ECOS) and canola seed (ECAS) in the diet of male Mehraban lambs on the concentration of unsaturated fatty acids in their plasma, erythrocytes and livers. The treatments were: (1) control (C); (2) diet C+6% ECAS, (3) diet C+6% ECOS, (4) diet C+12% ECAS, (5) diet C+12% ECOS, (6) diet C+6% ECAS+6% ECOS, (7) diet C+12% ECAS +6% ECOS, (8) diet C+6% ECAS +12% ECOS, (9) diet C+12% ECAS+12% ECOS, (10) diet C+18% ECAS+18% ECOS. A complete randomized experimental design was applied. Sixty lambs (5 -6 months of age) were randomly allocated to the 10 dietary treatments in order to have six lambs (replicates) per diet. The lambs were housed in individual pens. The average weight of lambs at the onset of the study was 34.3 ± 2.12 kg. The experiment lasted for 90 days. Results indicated that the concentration of oleic acid (C18:1), linoleic acid (C18:2 n-6) and linolenic acid (C18:3 n-3) in the plasma and oleic acid and linolenic acid in erythrocyte lipids were higher in lambs fed diets containing oil seeds or a combination of the oil seeds compared to those receiving the control diet. The supplementation of 6% and 12% ECAS increased the linoleic acid concentration in the liver lipids significantly compared to those fed the diets containing ECOS. There was a linear correlation between linoleic acid content of the liver and levels of dietary ECAS and ECOS. This study provides evidence that dietary oleic acid, linoleic acid and linolenic acid might escape biohydrogenation in the rumen and showed that the type of dietary fat has a marked impact on lipid metabolism in the liver. ________________________________________________________________________________
