The purpose of this study was to examine the fatty acid and chemical composition of the Longissimus dorsi (LD) from male Tuj and Hemsin lambs reared in extensive, semi-intensive and intensive feeding systems. At the end of 90 days eight lambs from each breed and feeding system were slaughtered to determine chemical composition, and six lambs in each group were selected at random to assess fatty acid composition. Breed and feeding system interaction affected the quantities of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA), and the atherogenic (AI), thrombogenic (TI), and nutritive value (NVI) indices. In Hemsin the ratio of PUFA to SFA was higher in lambs fed in the extensive system than those produced in the semi-intensive and intensive systems, which were similar, whereas in Tuj this ratio decreased from the extensive to semi-intensive to intensive feeding systems. The ratio of omega n-6 to omega n-3 fatty acids was lower in the extensive and semi-intensive systems than it was in intensively fed Hemsin lambs, but increased with the intensity of feeding in Tuj lambs. Intramuscular fat content was higher in Hemsin lambs than in Tuj lambs and increased with the intensity of the feeding system. Conjugated linoleic acid content (CLA) was affected by feeding system in Hemsin lambs, but not in Tuj lambs. Because of their high PUFA/SFA ratio and low TI value, Tuj lambs reared in extensive feeding system were deemed to have the best performance.

Abstract In an anonymous online study of 242 Jewish-identified participants (71 men, 163 women, 8 other; mean age = 37.8 years) living in ethnically diverse communities we found levels of antisemitism significantly associated with depression, survivor guilt proneness, and self-hate. Involvement in the Jewish community was significantly associated with life satisfaction even when adjusting for the effects of discrimination. A subsample of 124 responded to open ended questions with narratives. Thirty percent indicated feeling unsafe when identifying as Jewish.

Resumen En un estudio online y anónimo de 242 participantes identificados como judíos (71 hombres, 163 mujeres, 8 otros; media de edad = 37,8 años) que viven en comunidades étnicamente diversas, encontramos niveles de antisemitismo significativamente asociados con la depresión, la propensión a la culpa del sobreviviente y el odio a sí mismo. La participación en la comunidad judía se asoció significativamente con la satisfacción con la vida, incluso cuando se ajusta a los efectos de la discriminación. Una sub muestra de 124 personas respondió a preguntas abiertas con narrativas. El treinta por ciento indicó sentirse inseguro al identificarse como judío.

O estudo objetivou determinar os efeitos da suplementação com chito-oligossacarídeos (COS) e L-carnitina, individualmente ou em conjunto, sobre o desempenho, características de carcaça e alguns parâmetros sanguíneos em codornas. Um total de 192 codornas japonesas, com quatro dias de vida foi separado em quatro grupos, cada grupo com quatro repetições (12 aves por repetição). Os grupos receberam a mesma dieta basal suplementada com 0 (Controle), 150mg/kg chito-oligossacarídeos (COS), 150mg/kg L-carnitina (Carnitina), e 150mg/kg chito-oligossacarídeos +150 mg/kg L-carnitina (COS+Car.) durante o período inicial (1 a 21 dias) e de crescimento (22 a 42 dias). A fase de alimentação mostrou que COS, L-carnitina e COS+L-carnitina não tiveram efeito significativo no peso vivo, ganho de peso vivo, consumo de alimento e conversão de alimento. A suplementação com COS+L-carnitina induziu proporção de perna maior que o Controle. Não houve diferenças na concentração de albumina sérica, proteína total, glicose e colesterol total. Conclui-se que devido à proporção maior de perna obtida para o grupo COS+Car., após análise de perda e ganho, se for economicamente viável chito-oligossacarídeos+L-carnitina pode ser adicionado à dieta de codornas.

The aim of this study was to determine effects of dietary supplementation with chitosanoligosaccharides (COS) and L-carnitine, individually or dually, on growth performance, carcass traits and some blood serum parameters in quails. A total of 192, four days old, Japanese quail chicks were allotted four groups, each of which included four replicates (12 birds per replicate). The groups received the same basal diet supplemented with 0 (Control), 150mg/kg chitosanoligosaccharides (COS), 150mg/kg L-carnitine (Carnitine), and 150 mg/kg chitosanoligosaccharides+150 mg/kg L-carnitine (COS+Car.) during the starter (1 to 21 days) and a grower (22 to 42 days) period. The feeding trial shoved that COS, L-carnitine and COS+L-carnitine had no significant effect on live weight, live weight gain, feed consumption and feed conversion. Supplementation with COS+L-carnitine induced higher leg ratio from than that of the Control. There were no differences on serum albumin, total protein, glucose and total cholesterol concentrations. It is concluded that due to the obtained higher leg ratio from COS+Car. group, after analysis of the profit and loss, if is economically profitable, chitosanoligosaccharides+L-carnitine could be added quail diets.
