Thirty three male tudanca young bulls were used to evaluate 2 production systems (intensive and semiextensive) and 2 slaughter ages (12 and 14 months). Although there were differences in the average daily gains along the finishing period between groups, no differences were observed in conformation score. In contrast, production system affected fatness score. Semiextensive feed animals slaughtered at 12 months of age presented values of fatness scores lower than other groups (p

The use of markers-derived metrics has been suggested to infer relative inbreeding from the homozygosity of markers. Automated genotyping systems yield accurate genotypes of multiple SNPs which are useful markers for this goal. In the present study, 322 pigs of the Torbiscal closed strain of Iberian pigs have been genotyped for 192 selected SNPs, using the GoldenGate Genotyping Assay. The animals proceed from 56 litters born from minimum or maximum coancestry matings.

The Celta pig breed was the most important in Galicia (northwest of Spain) until beginning of the 20th century, suffering from this moment a continuous decrease caused by the introduction of improved breeds and their crosses. For this study 19 Celta pig breed from Santiaguesa genotype and 15 from Carballina genotype were used. Animals were weighted once at month during 12 months. To Santiaguesa genotype not significant differences (P>0.05) were observed until 198 days but it has been detected significant differences (P0.05) in any growth curve between gender.

Information on water use is required for political, economic and academic decision making on issues affecting everyone?s life.

Techniques and methodologies are, therefore, used to affordably maximize control. To improve understanding of the different techniques and methodologies used to generate information, the AQUASTAT team sent thematic questionnaires to approximately 170 countries in April 2009.
