| ABSTRACT This study used path analysis to establish the direct, indirect, and total effects of body linear and angular measurements on subjective morphological scores of the 247 Criollo horses that participated in their most important performance event, Freio de Ouro, in 2012. Freio de Ouro is the only event of the Criollo breed that considers morphology. Measurements of wither height, thoracic girth, cannon bone girth, body length, metatarsus length, croup length, shoulder width, head length, neck length, and upper neck girth, and the angles of rump, shoulder, and hock were taken. These morphometric measurements collectively explained 83% of the variation in morphological score. The measurements with the greatest total effects on score were neck length... |

| ABSTRACT The objective of this study was to quantify linear and angular morphological measurements of male and female horses participating in the Freio de Ouro competition. This study represents the first scientific evaluation of the biometrics of the Criollo breed, providing essential information for the evaluation of the development of the breed and supporting objective selection. We examined linear and angular measurements of 634 Criollo horses participating in the Freio de Ouro competition in 2011 and 2012, including height, chest circumference, cannon bone circumference, body length, metatarsus length, croup length, chest width, head length, dorsal neck length, throat circumference, and angles of the croup, scapula, and hock. Statistical analysis... |

| O objetivo deste trabalho foi avaliar a diversidade genética de um estoque de Salminus brasiliensis utilizado em programas de repovoamento do rio Paranapanema, por meio do marcador RAPD. Dez reprodutores (cinco machos e cinco fêmeas) e sua progênie (40 larvas e 40 alevinos) foram analisados. Os oito iniciadores analisados produziram 96 fragmentos, dos quais 81,2% foram polimórficos. Houve diferença significativa na frequência de 32 dos 96 fragmentos, com a presença de um fragmento exclusivo nos alevinos. O índice de Shannon, a percentagem de fragmentos polimórficos e a distância e a identidade genética mostraram menor divergência genética entre os reprodutores e as larvas, além de diminuição da variabilidade nos alevinos. A divergência genética foi menor... |

| The objective of this study was to evaluate the genetic diversity and the parental contribution of Piaractus mesopotamicus in the production of offspring in the semi-natural system of reproduction. Twenty parental fishes (eleven males and nine females) and the total of 100 larvae were evaluated by microsatellite marker. The parents and offspring had thirty-one alleles and heterozygosity of 0.550 and 0.563, respectively. The females were fertilised by two up to six males while the males fertilised three up to five females. The contribution of the females and males to the offspring were 66.6 and 58%, respectively. Such results indicated no loss in the genetic variability in the offspring, and the parents had multiple paternity and reasonable contribution to... |

| O experimento foi conduzido na Estação Experimental da Embrapa, Bagé, Rio Grande do Sul, entre março de 2005 e fevereiro de 2006. O objetivo foi avaliar o comportamento materno-filial e o temperamento de ovelhas e cordeiros e relacioná-los com a sobrevivência dos cordeiros. Foram utilizadas 47 ovelhas da raça Corriedale, com peso médio de 52,1kg, e 45 ovelhas da raça Ideal, com peso médio de 49,5kg, em um delineamento inteiramente casualizado. O temperamento foi avaliado por meio dos testes: escore de comportamento materno (ECM), tempo de fuga, tipo de marcha e distância de fuga. As ovelhas da raça Corriedale apresentaram maiores valores no teste tipo de marcha que as ovelhas da raça Ideal. Os cordeiros da raça Corriedale eram os mais pesados e tinham... |

| ABSTRACT This study aimed to develop PCR assays, reaction combinations, and validation of tetranucleotide SSR loci for tilapia, to minimize the impact of erroneous allele inferences on genotype determination of this marker. Microsatellites containing tetranucleotide repeats were obtained from tilapia genome, version 2.1, avoiding loci in the same linking group. Primers were designed for different fragment sizes, and fluorescence added to each locus. A total of 10 loci were amplified, separately and in combination, and loaded into a single capillary sequencer panel. Alleles were amplified without stutters and easily interpreted. PCR amplifications of DNA repeatedly extracted from samples, and genotyping at different PCR rounds were performed to infer allele... |
