Abstract: The aim of this study was to explore spatial patterns of genetic structure in sheep breeds sampled in Brazil using Single Nucleotide Polymorphisms (SNPs) in order to evaluate whether or not the genetic and geographic dis-tances are interrelated in this species. Samples genotyped using the 50KSheepSNPChip (Illumina) included 215 animals from eight different sheep breeds. All collection sites were georeferenced and data analyzed to determine geographic patterns from genetic data. To evaluate the correlation between genetic and geographic distances Mantel tests, Allelic Aggregation Index Analyses (AAIA), and spatial autocorrelation were performed. Genetic Landscape Shape procedure and Monmonier?s Algorithm were used to generate graphical visualization of the genetic distances across the landscape. The observed correlation observed between genetic and geographical distances was 0.552 (P <0.00099). Observed AAIA results (Rave =0.16, P <0.001) indicated a non-random distribution of genotypes across the landscape. High genetic differentiation was observed in the Southern re-gions of Brazil, separating wool and hair sheep. Low genetic distances were observed between flocks and breeds from north and center-west regions, and may be the result of unrecorded introgressions resulting from past unknown crossbreeding events. Observed Spatial Autocorrelation Analyses results indicate a minimum distance of 400 km should be used between collection sites to maximize genetic variability in future germplasm samplings for conservation of genetic resources.

Abstract - The objective of this work was to determine the effect of L-carnitine supplementation on the productive performance and physiology of juvenile pacu (Piaractus mesopotamicus). A total of 288 pacu, with an initial average weight of 9.62±0.74 g, were fed experimental diets supplemented with 400, 800, 1,200, 1,600, and 2,000 mg kg-1 L-carnitine and a control diet (without supplementation), for 128 days. The following were evaluated: growth performance; carcass centesimal composition; intestinal, muscle, and hepatic histomorphologies; and oxidative stress. The fish hepatosomatic and viscerosomatic fat indexes increased with the inclusion of L-carnitine in the diets. The evaluation of carcass centesimal composition showed that the diets supplemented with 2,000 mg kg-1 L-carnitine caused a reduction in protein content and an increase in that of ethereal extract. Intestinal histomorphology indicated changes in the villi with L-carnitine supplementation. Moreover, hepatic lipid peroxidation occurred with the inclusion of 2,000 mg kg-1 L-carnitine. The supplementation with L-carnitine in the diets of pacu juveniles does not influence the development of the fish until the rate of 1,600 mg kg-1. However, high carcass lipid levels, as well as an increase in the hepatosomatic and viscerosomatic fat indexes, are observed in fish fed diets containing 2,000 mg kg-1. Resumo - O objetivo deste trabalho foi determinar o efeito da suplementação de L-carnitina no desempenho produtivo e na fisiologia de juvenis de pacu (Piaractus mesopotamicus). Um total de 288 pacus, com peso inicial médio de 9,62±0,74 g, foram alimentados com dietas experimentais suplementadas com 400, 800, 1.200, 1.600 e 2.000 mg kg-1 de L-carnitina e com uma dieta controle (sem suplementação), por 128 dias. Foram avaliados: desempenho produtivo; composição centesimal da carcaça; histomorfologias intestinal, muscular e hepática; e estresse oxidativo. Os índices hepatossomático e de gordura viscerossomática dos peixes aumentaram com a inclusão de L-carnitina nas rações. A avaliação da composição centesimal da carcaça mostrou que as dietas suplementadas com 2.000 mg kg-1 de L-carnitina causaram redução no conteúdo de proteína e aumento no de extrato etéreo. A histomorfologia intestinal indicou alterações nas vilosidades com a suplementação de L-carnitina. Além disso, a peroxidação lipídica hepática ocorreu com a inclusão de 2.000 mg kg-1 de L-carnitina. A suplementação de L-carnitina em dietas para juvenis de pacu não influencia o desenvolvimento dos peixes até a dose de 1.600 mg kg-1. Entretanto, observam-se elevados níveis de lipídeos na carcaça, assim como aumento nos índices hepatossomáticos e de gordura viscerossomática, em peixes alimentados com rações contendo 2.000 mg kg-1.
