| We investigated the genealogy of the in situ conservation nucleus of the Pantaneiro horse using DNA microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). Genomic DNA was extracted from hair roots and genotyped using 12 microsatellite markers (AHT4, AHT5, ASB2, ASB17, ASB23, HMS3 HMS6, HMS7, HTG4, HTG10, LEX33 and VHL20). The number of alleles per locus varied from 6 to 13, with a mean of 7.8 and the expected heterozygosity ranged from 0.544 to 0.734 (mean 0.644). The VLH20, ASB2, HTG10, ASB23 markers had a high (> 0.8) polymorphism information content and the total exclusion probability of the 12 microsatellite loci was 0.99. The genealogical study of... |

| El objetivo de este trabajo fue establecer la relación genética entre poblaciones bovinas panameñas Guabalá y Guaymí y algunas poblaciones criollas de Latinoamérica. Se practicó un análisis factorial de correspondencias, análisis de varianza molecular, distancias genéticas, número medio de migrantes por población y los estadísticos F de Wright. Se evaluó la estructura de la población mediante un modelo Bayesiano, suponiéndose un número desconocido de K grupos diferentes genéticamente. El análisis factorial de correspondencias mostró que las poblaciones Guabalá y Guaymí se agrupan con los bovinos criollos mexicanos y el Texas Longhorn. Igualmente se observó menor diferenciación genética de las criollas panameñas con mexicanos y el Texas Longhorn. Los... |

| It was evaluated in this study the environmental effects on body weights of goat kids from birth to 150 days of age of Tunisian local goat population, on the basis of 1,656 records obtained from the Arid Areas Institute of Médenine, Tunisia, during 2001-2005. Except for birth weight, individual records were adjusted for standard ages (30, 60, 90, 120 and 150 days) using either extrapolation or interpolation on field data. Data were analyzed by GLM procedure and SNK (α = 0.05) means comparison test. The kidding year (2001-2005), kidding month (December, January, February, and March), birth type (single and twins), sex (male and female), coat colour of kid and age of dam (2-10 years) were definied as non-genetic factors. Results showed that mean values and... |
