“…Interestingly, the differences observed in intramuscular and subcutaneous lamb fat reflected those found in their mother's milk. Despite changes due to the treatments administered, the FA composition values observed in this study are within the range of those reported earlier by Cañ eque et al (2005) and Osorio et al (2007) for suckling lambs, and similar to those observed in suckling kids (Sanz Sampelayo et al, 2006;Nudda et al, 2008).…”

“…Arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5n-3) levels are similar in milk and subcutaneous fat, but greater concentrations of these FAs were found in intramuscular fat samples. This is because 20:4n-6 and 20:5n-3 are mainly incorporated into the phospholipid fraction in the muscle, whereas these FAs are found in much smaller quantities in the triglycerides of adipose tissue (Sanz Sampelayo et al, 2006).…”

“…Thus, supplementing dairy animal diets with different lipid sources modifies the FA profile of sheep and goat milk, and increases the levels of healthy FAs, such as CLA and n-3 FA (Sanz Sampelayo et al, 2006;Nudda et al, 2008). Research conducted on goat meat has shown that calcium salt or linseed supplementation of the dam diet can alter the FA composition of suckling kid meat (Sanz Sampelayo et al, 2006;Nudda et al, 2008). Changes in milk FA composition (due to the ewe feeding system or the use of milk replacers) can induce differences in the FA composition of suckling lamb meat or edible fat, as previous studies have reported (Lanza et al, 2006;Osorio et al, 2007;Serra et al, 2009).…”

The objective of this study was to evaluate the effects of vegetable oil supplementation of ewe diets on the performance and fatty acid (FA) composition of their suckling lambs. Forty-eight pregnant Churra ewes (mean BW 64.3 6 0.92 kg) with their 72 newborn lambs (prolificacy 5 1.5) were assigned to one of four experimental diets, supplemented with 3% of hydrogenated palm (PALM), olive (OLI), soya (SOY) or linseed (LIN) oil. Lambs were nourished exclusively by suckling from their respective mothers. Ewes were milked once daily, and milk samples were taken once a week. When lambs reached 11 kg, they were slaughtered and samples were taken from musculus longissimus dorsi (intramuscular fat) and subcutaneous fat tissue. No changes were observed in milk yield, proximal composition or lamb performance (P . 0.10). Milk and lamb subcutaneous and intramuscular fat samples from the PALM diet had the highest saturated fatty acid concentration, whereas those of the OLI, SOY and LIN diets had the lowest (P , 0.05). The greatest monounsaturated fatty acid concentration was observed in milk from ewes fed OLI, and the least in milk and in lamb subcutaneous and intramuscular fat samples from LIN and PALM diets. Milk and lamb fat from ewes fed PALM displayed the highest 16:0 proportion and the lowest 18:0 (P , 0.05). There were higher concentrations of cis-9 18:1 in OLI samples (P , 0.05), more 18:2n-6 in SOY lambs and milk fat (P , 0.001) and the highest levels of 18:3n-3 and 20:5n-3 in LIN samples (P , 0.01). Milk and lamb subcutaneous and intramuscular samples from SOY and LIN diets contained the most cis-9, trans-11 conjugated linoleic acid, whereas PALM samples had the least (P , 0.01). Sheep diet supplementation with different oils, constituting up to 3% of their diets, resulted in changes in the FA composition of milk and the subcutaneous and intramuscular fat of suckling lambs, but did not affect either milk production or lamb performance.

“…On the other hand, the mechanism for reducing triglycerides in blood of suckling kids of dams fed fat source rich in PUFA is due to that the PUFA reduced the lipolysis and thus led to lower plasma levels of not esterified fatty acids (NEFA) which subsequently lead to lower levels of triglycerides (Sampelayo et al, 2006).…”

A study was conducted to determine the effect of feeding soyabean or sunflower oil to lactating Shami goats on milk production, composition and fatty acid profile. Goats (n=125), 2 to 4 years of age and 55 to 60 kg liveweight, were randomly assigned to 5 treatment groups (25 each) in a completely randomized design. Diets were: a control ration (C), control supplemented with 3% soyabean oil (3%SBO), control supplemented with 5%SBO, control supplemented with 3% sunflower oil (3%SFO), and a control supplemented with 5%SFO. Variables measured were milk production, milk composition, dry matter intake, body weight, weaning weight of kids, blood metabolites, and milk and blood fatty acid profiles. Daily milk production was reduced (P<0.05) in most treatments. Fat and protein yields were maximum (P<0.05) at 3%SBO while energy corrected milk was highest (P<0.05) for the 3%SBO. Feed intake was least (P<0.05) for the 3%SFO group and feed to milk ratio was highest (P<0.05) for the 3% SBO group. Values for the serum cholesterol were highest (P<0.05) for the SBO kids. Meanwhile, triglycerides were reduced (P<0.05) following oil treatment with the lowest (P<0.05) value in the serum of the 5%SBO kids. Total conjugated linoliec acid (CLA) content in milk was mostly increased (P<0.05) for oil treated goats. In the blood of kids, total CLA was maximum (P<0.05) for kids of the 5%SFO group.Results indicate that supplementing lactating goat diet with either oils did not improve milk production, milk composition, or growth rate and weaning weight of their kids, but improved their energy corrected milk and CLA content. However, only SBO increased cholesterol level in the blood in kids.

In this study, sh oil was used as an omega-3 fatty acids source in pregnant goat's rations in the different periods of pregnancy on mature male offsprings performance. Forty-seven male goat kids (84.6 ± 2.44 days or days old; 14.5 ± 3.09 kg body weight) were housed in individual pens and to evaluate live weight, feed consumption, serum biochemical parameters, carcass performance and meat quality characteristics for 56 days. Supplementation of sh oil to Anaç goats dam ration during the gestation periods decreased the fattening live weight and increased feed consumption (p=0.09), while body weight and feed conversion rates were not affected by experimental treatments (p=0.62, p=0.90). Fish oil increased serum AST, glucose, total protein, and globulin concentrations (p=0.02, p=0.01, p=0.03, p=0.02), while decreased heptadecanoic acid, oleic acid, linoleic acid, docosahexaenoic acid, and total mono-and polyunsaturated fatty acid concentrations in M. longissimus dorsi muscle (p=0. 09, p=0.03, p=0.10, p=0.02, p=0.02, p=0.09). As a result, it has been thought that the use of liquid sh oil as an omega-3 source in goat's ration during gestation may negatively affect the fetal development of male kids, but it has the ability to eliminate this negativity by improving post-weaning performance. Determination of Biochemical ParametersIndividual blood samples were taken from the vena jugularis with serum tubes containing gel (9 ml, Ayset, Turkey) before morning feeding at the beginning (day 1), middle (day 28) and end (day 56) of the fattening period.The collected blood samples were transported to the Department of Feeds and Animal Nutrition Laboratory rapidity, where they were centrifuged at 4°C and 4000 rpm for 15 minutes (Universal 320R, Hettich, Germany), and the obtained sera were transferred into 1.5 ml Eppendorf tubes with the protocol number, and they were stored at -20°C until analyses. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT) and alkaline phosphatase (ALP) activities, albumin, total protein, total cholesterol, glucose, triglycerides, magnesium, calcium concentrations in sera were detected on a biochemistry analyzer (BS-120 Vet, Mindray, China) with the commercially available kits provided by the manufacturer of the analyzer.Globulin level was calculated by subtracting albumin value from total protein value. Collection of Data Related to Carcass and Meat QualityAt the end of the fattening period, 5 kids from each treatment group having live weight close to mean live weight were slaughtered in a private slaughterhouse.After slaughter, slaughter weight, skin, heart + lung (set), liver and hot carcass weights were recorded. The carcasses were stored at +4°C for 24 hours in a cold storage room. At the end of this period, cold carcass, fat around kidneys, cervical (neck), thigh, shoulder head, arm, lumbar (waist) and ank weights were determined (Darcan et al, 2006;Atay et al, 2007).Color, pH, texture and fatty acid analyses were performed on 15 gr muscle samples take...
