(CL) and a vegetable oil blend were evaluated on growth performance, carcass and meat quality of fifty four lambs that were assigned to 9 diets, corresponding to 3 levels of CL (50, 100 and 200 g/kg DM) and 3 levels of oil inclusion (0, 40 and 80 g/kg DM). Treatments had no effects on growth rate. Oil depressed dry matter intake (P = 0.017), carcass muscle (P = 0.041) and increased (P = 0.016) kidney knob channel fat. Chemical and physical meat quality traits were not affected by treatments. Off-flavour perception was higher for 8% of oil (P &lt; 0.001). The level of 100 g/kg DM of CL inclusion improved meat stability after 7 days of storage. Supplementation with linseed and soybean oils (2:1) was a good approach to improve meat nutritional value from feedlot lambs, increasing total n-3 PUFA.</style></abstract><accession-num><style face="normal" font="default" size="100%">25460137</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Monteiro, Ana C G</style></author><author><style face="normal" font="default" size="100%">Gomes, Eduardo</style></author><author><style face="normal" font="default" size="100%">Barreto, António S</style></author><author><style face="normal" font="default" size="100%">Silva, Marina F</style></author><author><style face="normal" font="default" size="100%">Fontes, Magda A</style></author><author><style face="normal" font="default" size="100%">Bessa, Rui J B</style></author><author><style face="normal" font="default" size="100%">Lemos, José P C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Eating quality of “Vitela Tradicional do Montado”-PGI veal and Mertolenga-PDO veal and beef</style></title><secondary-title><style face="normal" font="default" size="100%">Meat Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Beef</style></keyword><keyword><style  face="normal" font="default" size="100%">meat quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Mertolenga</style></keyword><keyword><style  face="normal" font="default" size="100%">Sensory analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Veal</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><volume><style face="normal" font="default" size="100%">94</style></volume><pages><style face="normal" font="default" size="100%">63-68</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract Physicochemical and sensory characteristics were measured in veal and beef from the Portuguese Mertolenga breed having 3 quality labels as follows: Mertolenga-PDO beef and veal which apply to purebred animals and “Vitela Tradicional do Montado”-PGI veal which applies to crossbred animals. Measurements were made in longissimus lumborum muscle aged for 6 days. The temperature 3 h post-mortem (T3), cooking losses and Warner–Bratzler shear force (WBSF) reflected carcass weight (CW) differences between groups. The pigment content was influenced by age, with beef having higher values than veal. WBSF correlated negatively with intramuscular fat in Mertolenga-PDO beef, but not on veal. WBSF correlated positively with cooking losses and negatively with myofibrillar fragmentation index, tenderness, juiciness and overall acceptability. Cooking losses and juiciness were the main contributors for the tenderness differences. Vitela Tradicional do Montado-PGI and Mertolenga-PDO veal had lighter colour and were considered tender. The three meat types were well discriminated based on pHu, a* and C* parameters by canonical discriminant analysis.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">a.

All the meats analysed had similar contents (P &gt; 0.05) of cholesterol, a-tocopherol and intramuscular fat. In contrast, the percentage of 18:0 was lower for PGI veal, and that of 18:1 c9 was higher in PDO veal, whilst the percentage of 18:2 n6 was higher in PDO beef, relative to other two meats. The content of total CLA and the percentage of its t11,c13 isomer were higher, and the n6/ n3 ratio was lower, in PDO veal, relative to the other two meats. The data suggested that PGI veal has higher variability for most fatty acids than the other two types of meat. Finally, a discriminant analysis was conducted and the three meat types were well discriminated using the meat fatty acid proﬁle as variables.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;label: Beef;CLA isomers;Cholesterol;Fatty acids;Meat quality;a-Tocopherol</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Quaresma, M a G</style></author><author><style face="normal" font="default" size="100%">Trigo-Rodrigues, I</style></author><author><style face="normal" font="default" size="100%">Alves, S P</style></author><author><style face="normal" font="default" size="100%">Martins, S I V</style></author><author><style face="normal" font="default" size="100%">Barreto, a S</style></author><author><style face="normal" font="default" size="100%">Bessa, R J B</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nutritional evaluation of the lipid fraction of Iberian red deer (Cervus elaphus hispanicus) tenderloin.</style></title><secondary-title><style face="normal" font="default" size="100%">Meat science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">cervus elaphus hispanicus</style></keyword><keyword><style  face="normal" font="default" size="100%">Cholesterol</style></keyword><keyword><style  face="normal" font="default" size="100%">CLA</style></keyword><keyword><style  face="normal" font="default" size="100%">Fatty acid profile</style></keyword><keyword><style  face="normal" font="default" size="100%">meat quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Vitamin E</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><volume><style face="normal" font="default" size="100%">92</style></volume><pages><style face="normal" font="default" size="100%">519-524</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The meat lipid fraction of psoas major muscle from 20 adult (10 males and 10 females) feral Iberian red deer (Cervus elaphus hispanicus) was characterized by quantification of total fat, total cholesterol, vitamin E and fatty acid (FA) composition, including detailed trans octadecenoate isomers and conjugated linoleic acid (CLA) isomeric profile. The total lipid content revealed a very lean meat (0.99 g/100g of meat), with total cholesterol content averaging 55.6 mg/100g of muscle. The FA profile displayed a very high PUFA level for ruminant meat (30.2g/100g FA). The 18:2 cis-9,trans-11 content was fairly low (0.26% of total FA) compared with other ruminant meats.

In the literature, it is evident that the breeds native to southern Europe have an interesting quality of products with respect to improved pigs. The free-range system increases the value of animal products due to the influence of outdoor rearing on the chemical, physical and organoleptic characteristics of the product. Traditional food products of high quality, such as those obtained from animals reared outdoor, are in high demand. The studies carried out on native pig breeds in southern Europe have focused on various aspects, ranging from studies of population genetics aimed at averting the danger of extinction and reducing inbreeding to studies of the factors affecting the quality of products. The purpose of this review is to analyse the literature on pig breeds native to southern Europe, with particular reference to the effects of genetics and breeding systems on the quality of products.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd&lt;br/&gt;accession-num: 22030111</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Quaresma, M a G</style></author><author><style face="normal" font="default" size="100%">Alves, Susana P</style></author><author><style face="normal" font="default" size="100%">Trigo-Rodrigues, I</style></author><author><style face="normal" font="default" size="100%">Pereira-Silva, R</style></author><author><style face="normal" font="default" size="100%">Santos, N</style></author><author><style face="normal" font="default" size="100%">Lemos, J P C</style></author><author><style face="normal" font="default" size="100%">Barreto, a S</style></author><author><style face="normal" font="default" size="100%">Bessa, R J B</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Nutritional evaluation of the lipid fraction of feral wild boar (Sus scrofa scrofa) meat.</style></title><secondary-title><style face="normal" font="default" size="100%">Meat science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cholesterol</style></keyword><keyword><style  face="normal" font="default" size="100%">fatty acids</style></keyword><keyword><style  face="normal" font="default" size="100%">meat quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Vitamin E</style></keyword><keyword><style  face="normal" font="default" size="100%">Wild boar</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><volume><style face="normal" font="default" size="100%">89</style></volume><pages><style face="normal" font="default" size="100%">457-461</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Consumer increasing demand for wild boar meat and scarceness of data on its lipid fraction justified this study.

Intramuscular fat and total cholesterol contents averaged 4.64 g/100g of meat and 56.9 mg/100g of meat, respectively. No differences were found in FA composition between groups, except for 20:5n-3 that was higher in youngsters. All groups presented small concentrations of rumenic acid in meat (CLA; 0.24% of total FA). FA profile showed considerable resemblance with pork, while the vitamin E profile is marked by high concentrations of both alpha- (17.4 ± 3.3 μg/g meat) and gamma-tocopherols (2.6 ± 1.3 μg/g meat) and by the presence of other vitamin E homologues not previously reported in wild boar meat.</style></abstract><accession-num><style face="normal" font="default" size="100%">21658850</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Alfaia, C M M</style></author><author><style face="normal" font="default" size="100%">Ribeiro, V S S</style></author><author><style face="normal" font="default" size="100%">Lourenço, M R a</style></author><author><style face="normal" font="default" size="100%">Quaresma, M a G</style></author><author><style face="normal" font="default" size="100%">Martins, S I V</style></author><author><style face="normal" font="default" size="100%">Portugal, a P V</style></author><author><style face="normal" font="default" size="100%">Fontes, C M G a</style></author><author><style face="normal" font="default" size="100%">Bessa, R J B</style></author><author><style face="normal" font="default" size="100%">Castro, M L F</style></author><author><style face="normal" font="default" size="100%">Prates, J a M</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fatty acid composition, conjugated linoleic acid isomers and cholesterol in beef from crossbred bullocks intensively produced and from Alentejana purebred bullocks reared according to Carnalentejana-PDO specifications.</style></title><secondary-title><style face="normal" font="default" size="100%">Meat science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Beef</style></keyword><keyword><style  face="normal" font="default" size="100%">Cholesterol</style></keyword><keyword><style  face="normal" font="default" size="100%">CLA isomers</style></keyword><keyword><style  face="normal" font="default" size="100%">fatty acids</style></keyword><keyword><style  face="normal" font="default" size="100%">meat quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Production systems</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><volume><style face="normal" font="default" size="100%">72</style></volume><pages><style face="normal" font="default" size="100%">425-436</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The purpose of this study was to characterise and compare the nutritional value of Portuguese Carnalentejana-PDO beef, obtained from Alentejana purebred bullocks reared in a semi-extensive system, with the meat from Alentejana×Charolais crossbred bullocks produced in a conventional intensive concentrate-based system. In addition, seasonal changes in Carnalentejana-PDO beef quality were assessed, by analysing meat samples from animals slaughtered in early autumn and late spring.

Nevertheless, from a human nutrition perspective, Carnalentejana-PDO beef seems to be healthier than that from intensively reared animals since it has a lower n-6/n-3 ratio, although always above the recommended guidelines for human diet, and higher proportions of c9,t11 conjugated linoleic acid (CLA) isomer and total CLA relative to saturated fatty acids plus total cholesterol (CLA/SFA+CHR).

Taken together, the data indicate that Carnalentejana-PDO beef is of greater nutritional value than intensively produced beef from crossbred bullocks throughout the year.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 22061726</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Alfaia, Cristina M M</style></author><author><style face="normal" font="default" size="100%">Quaresma, Mário A G</style></author><author><style face="normal" font="default" size="100%">Castro, Matilde L F</style></author><author><style face="normal" font="default" size="100%">Martins, Susana I V</style></author><author><style face="normal" font="default" size="100%">Portugal, Ana P V</style></author><author><style face="normal" font="default" size="100%">Fontes, Carlos M G A</style></author><author><style face="normal" font="default" size="100%">Bessa, Rui J B</style></author><author><style face="normal" font="default" size="100%">Prates, José A M</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fatty acid composition, including isomeric profile of conjugated linoleic acid, and cholesterol in Mertolenga-PDO beef</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of the Science of Food and Agriculture</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CLA isomers</style></keyword><keyword><style  face="normal" font="default" size="100%">fatty acids</style></keyword><keyword><style  face="normal" font="default" size="100%">meat quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Mertolenga-PDO</style></keyword><keyword><style  face="normal" font="default" size="100%">total cholesterol</style></keyword><keyword><style  face="normal" font="default" size="100%">total lipids</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year></dates><publisher><style face="normal" font="default" size="100%">John Wiley &amp; Sons, Ltd.</style></publisher><volume><style face="normal" font="default" size="100%">86</style></volume><pages><style face="normal" font="default" size="100%">2196-2205</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper describes the fatty acid composition, including the isomeric distribution of conjugated linoleic acid (CLA), total lipids and cholesterol in longissimus dorsi (LD) and semitendinosus (ST) muscles of Mertolenga beef from young bulls reared according to Protected Designation of Origin (PDO) specifications. Mertolenga purebred young bulls (n = 30) were raised in a semi-extensive production system, including a finishing period on concentrate feeds for the last 5 or 3 months (October and June samplings, respectively). Mertolenga-PDO beef showed seasonal changes in the levels of some fatty acids (including the predominant 18:2n-6), sums of trans fatty acids and n-3 polyunsaturated fatty acids, some CLA isomers (t11,t13, t11,c13 and t10,c12), sums of geometric groups of CLA isomers and total cholesterol. In addition, significant differences were obtained between LD and ST muscles for most of the analysed parameters. From a nutritional perspective, beef-PDO from June seems to be more healthful than that from October as a consequence of its lower n-6/n-3 ratio. Moreover, the results suggest that the polyunsaturated fatty acid/saturated fatty acid ratio in the ST muscle is consistently above the recommended guideline for human diets, although the values were below that guideline for the LD muscle. Taken together, the data indicate that, although the finishing period of Mertolengo young bulls on concentrate attenuates most of the beneficial grass effects on meat fat throughout the year, beef-PDO from late spring is of greater nutritional value than that from early autumn.
