ABSTRACT.
Characterized as the most important gastrointestinal parasite (GIP) in the world, Haemonchus contortus is also the most predominant and pathogenic genus in Uruguay, causing high morbidity and mortality rates in sheep flocks. For approximately 26 years resistance to GIP has been included in the National Genetic Evaluation (NGE) of Corriedale and Merino breeds, using Faecal Egg Count (FEC) as the selection criterion. The aim of the present study was to estimate genetic parameters for FEC, post-weaning Body Weight (BW), Packed Cell Volume (PCV), FAMACHA© and Body Condition Score (BCS), to determine the possibility to include these traits in the NGE of GIP resistance and resilience, as complementary selection criteria and to investigate the sensitivity of breeding values to different environmental worm burden challenges. Data were collected on 19,510 lambs from 2000 to 2009 in 24 Corriedale studs that participated in the NGE of sheep in Uruguay. (Co)variances components were estimated using a multi-trait animal model performing a Bayesian analysis. Posterior means estimated for heritability (h2) were of low to moderate magnitude (between 0.10 and 0.33) for the traits analysed. Genetic correlations (rg) were not significantly different from zero for BW- Loge (FEC + 100), BW-FAMACHA©, BW-PCV, Loge (FEC + 100)-PCV, BCS-FAMACHA©, moderate favourable rg for Loge (FEC + 100)-FAMACHA and PCV-BCS (0.55, 0.41) and high favourable rg for BW-BCS (0.66). These results indicate the possibility to complement selection programs incorporating BW, Loge (FEC + 100), FAMACHA©, PCV and BCS in order to select resistant and resilient animal to GIP. Furthermore, genetic parameters for BW and Loge (FEC + 100) to different environmental worm burden challenge was investigated. Two contemporary groups of low worm environment (Loge (FEC + 100) below 6.40) and a high worm environment (Loge (FEC + 100) above 6.75) were considered. In this model, h2 estimated for BW and Loge (FEC + 100) were found to be not statistically different between low and high environmental worm burden, furthermore, high correlations between traits at both environments were also presented.

ABSTRACT.
The widespread use of artificial insemination has allowed the expansion of genetic progress. However, it also brought consequences such as the expansion of lethal hereditary diseases and the increase in inbreeding. The object of this study was to establish a fast and sensitive molecular assay to detect bovine leukocyte adhesion deficiency (BLAD) and deficiency of uridine monophosphate synthase (DUMPS) carriers in Uruguayan Holstein cattle by means of high resolution melting (HRM) curve analysis. By testing previously confirmed carrier and non-carrier animals, we set up a rapid, simple, and inexpensive diagnostic test using PCR followed by HRM curve analysis. The PCR-HRM genotyping method was effective for the discrimination of BLAD and DUMPS homozygous genotypes, and the BLAD heterozygous genotype. We conclude that the PCR-HRM assay is a robust, reliable, and economical tool for the detection of these mutations in the Holstein breed, which may be implemented in genetic selection programs.

RESUMO.
O uso generalizado de inseminação artificial, permitiu expandir o progresso genético, no entanto, também trouxe consequências na expansão de doenças hereditárias letais e aumento da endogamia. O objetivo deste estudo foi estabelecer um ensaio molecular rápido e sensível para detectar animais portadores da deficiência de adesão leucocitária bovina (BLAD) e da deficiência da uridina monofosfato sintetase (DUMPS) usando a análise de curva de alta resolução (HRM) em bovinos da raça Holandesa Uruguaia. Através do uso de animais portadores e não portadores previamente confirmados, montamos um teste de diagnóstico rápido, simples e de baixo custo usando PCR seguido de análise de curva HRM. O método de genotipagem da PCR-HRM foi efetivo para a discriminação dos genótipos homozigotos BLAD e DUMPS e do genótipo heterozigoto BLAD. Concluímos que o ensaio PCR-HRM é uma ferramenta poderosa, confiável e econômica para a detecção destas mutações na raça Holandesa, o que poderia ser implementado em programas de seleção genética.
