“…Nutritionists reported that a balance in the diet between n-6 PUFA and n-3 PUFA with a ratio below 4 is recommended to prevent coronary heart diseases. The n-6/n-3 ratio of IMF in kids and Ch lambs shown in this work (Table 1) is in line with the ratios reported for commercial Spanish lambs (range 6.4 to 8.4; Díaz et al, 2005) and higher that those reported by Sinanoglou et al (2013) in Greek breeds of small ruminants (range 2.9 to 5.8). Ch lambs and MG kids displayed a higher and unfavourable n-6/n-3 ratio than meat kid breeds (BC, Mo and NS), as they showed the highest percentage of PUFA C18:2 n-6c and lowest of long chain n-3 fatty acids (C20:5n-3; C22:5n-3 and C22:6n-3) ( Table 1).…”

“…Fatty acid profile of IMF from kids (BC, Mo, NS, MG breeds) and Ch lambs (Table 1) are in line with those reported in small ruminant animals raised in countries of the Mediterranean area (Sinanoglou et al, 2013). In fact, total C18:1 fatty acids (28.4 to 30.3%) are in agreement with those reported by Horcada et al (2012) in kids and Díaz et al (2005) in lambs.…”

“…The relative content of SFA was higher in all kid breeds than in lambs, and the highest SFA content was observed in meat kids (BC, Mo and NS). Influence of breed on SFA of KK fat can be proposed (Sinanoglou et al, 2013). Higher MUFA content was observed in Ch lambs than in kids (Table 2), while for PUFA content there were no clear differences between kids and Ch lambs.…”

“…This f inding suggests that in small ruminants this ratio is not influenced by genetics factors or differences in fat deposition. However, Sinanoglou et al (2013) reported signif icant differences in the hypercholesterolemic index (sum of C14:0 and C16: 0) in the IMF between kids and lambs. According to these authors, these differences are mainly associated with genetic factors.…”

“…Furthermore, recent experiments have shown the effectiveness of the fatty acid composition of intramuscular fat (IMF) depots as a tool to discriminate goat breeds or the use of kidney knob fat (KKF) as a method of differentiating the fattening diet of goat kids (Mellado et al, 2009). In spite of this there have been few comparative studies on the lipid composition of kid and certified lamb (Lee et al, 2008;Sinanoglou et al, 2013).…”

Fatty acid profiles are a major contributor to meat quality in small ruminants. Nevertheless, while fatty acid profiles from suckling lambs have been extensively studied they are virtually unknown in suckling kids. Fatty acid profiles of intramuscular and kidney knob fat depots of suckling kids were compared with fatty acid profiles of lambs with a quality label in the Spanish market. Forty suckling kids from Blanca Celtibérica (BC), Moncaína (Mo), Negra Serrana (NS) and Murciano Granadina (MG) breeds and 20 Churra male suckling lambs labelled with ‘Lechazo de Castilla y León’ Protected Geographic Indication were slaughtered at commercial live weights (12 kg). In both depots differences in the unsaturated fatty acid profile were observed between breeds. The most pronounced differences were observed between meat goat breeds (BC, Mo and NS) and lambs, whilst a greater similarity in the fatty acid profile was observed between kids from dairy goat breeds (MG) and lambs. The lowest polyunsaturated fatty acid content was observed in meat goat breeds (approximately 21 to 22% of total fatty acids detected in the intramuscular fat). No significant differences in atherogenic index and desirable fatty acid content (range 68 to 70% of total fatty acids detected) were observed. However, a more favourable (lower than 8.07) n-6/n-3 ratio was observed in meat goat breeds. The use of fatty acid profiles from intramuscular and kidney knob fat could be proposed as a tool to differentiate goat kids and lambs. The fact that intramuscular fat from suckling kids and lambs shows appropriate lipid nutritional indices and their low carcass fatness indicate that moderate consumption of suckling kid and lamb meat may contribute to an overall balanced diet for humans.
