ABSTRACT.- The evaluation of sheep feed intake (FI) in feed efficiency tests is expensive. Decreasing the test period could be a resource-saving tool by reducing the cost of evaluating each animal and allowing to test a greater number of animals per year. For this reason, the objective of this research was to explore residual feed intake (RFI) models and to decreasing the test duration. Data was collected from 286 Australian Merino sheep of three performed trials, the test period consisted of 56 days (14 days of feed and facilities adaptation and 42 days of FI and average daily gain (ADG) evaluation). Two models were used to calculate RFI, Model 1 (based on Koch et al. (1963) linear model) and Model 2 (repeated measures, weekly model). Model 1 included ADG and FI estimates in a linear regression. The second model included weekly average FI as repeated measure and the weekly ADG. The increase in body weight during the test period was not perfectly linear, presenting a marked variance increase in two of the three tests while FI presented a tendency to increase throughout of the evaluation period, however presenting a high variance per day. In the 42-days tests, Pearson and Spearman correlations between models for ADG were of 0.89 and 0.87, respectively. The best correlations were detected for FI between 42 and 35-days models, presenting Pearson and Spearman correlations of 0.95 and 0.94 in the linear model, and 0.96 and 0.95 in the weekly model. When considering RFI, the correlations between linear and weekly 42-days models were from 0.93 to 0.92, respectively. The 35-days RFI length models (linear and weekly) presented a Pearson and Spearman correlations greater than 0.98 with the 42-days models. Therefore, the RFI models 35-days of duration allowed to decrease seven days of the FI test while maintaining accuracy and explaining 75.3% of the FI in the linear model, and 63.6% of the weekly model. Reducing seven days of testing would provide a greater data collection into a year of phenotypic evaluation. © 2022 The Authors. Published by Elsevier B.V.

RESUMEN.- El objetivo de este estudio consistió en un relevamiento de las principales enfermedades hereditarias BLAD, DUMPs y Citrulinemia,
en una población representativa de terneras Holando de la región este del Uruguay utilizando el panel GGP-BovineLDv3, así como en el análisis de la frecuencia del alelo mutante de BLAD desde que fue reportado por primera vez en Uruguay. El ADN fue extraído a partir de sangre fresca de 190
terneras Holando de la cuenca lechera de Cerro Largo (Uruguay) y genotipado con el mencionado panel, validando así técnicas previamente utilizadas tales como PCR-RFLP y PCR-secuenciación. Se detectó la presencia del alelo mutante para BLAD en una ternera y se estimó una frecuencia alélica de 0.28 %. Las frecuencias reportadas del alelo BLAD durante los últimos 15 años fueron comparadas, encontrándose una disminución de la misma en los trabajos reportados hasta llegar a cero en 2018, lo cual podría deberse al uso de semen genotipado libre de estas enfermedades durante los últimos años. No se encontraron alelos mutantes para DUMPs ni para Citrulinemia. El uso de paneles de baja densidad sería una herramienta muy útil para establecer estrategias de cría en tambos y monitorear las enfermedades hereditarias en la raza Holando. ---------------------------------- SUMMARY.- The objective of this study consisted in a screening of the main hereditary diseases BLAD, DUMPs and Citrullinaemia using the GGP-BovineLDv3 panel in a representative population of Holstein heifers of the eastern area of Uruguay, as well as the
analysis of BLAD mutant allele frequency since it was first reported in Uruguay in 2003. DNA was extracted from fresh blood of 190 Holstein heifers in the dairy area of Cerro Largo (Uruguay) and genotyped using the above mentioned panel, thus validating previously used techniques, suhc as PCR- RFLP and PCR- sequencing. We detected the presence of the BLAD mutant allele in one heifer, and allele frequency was estimated as 0.28%. Reported frequencies of BLAD allele during the last 15 years were compared and the reported studies revealed that the frequency progressively decreased and fell to zero in 2018, which can be due to the use of genotyped semen free of these diseases during the last years. No mutant alleles were found for DUMPs or Citrulinaemia. The use of low-density panels would be a useful tool to develop breeding strategies in dairly farms
and to monitor hereditary diseases in Holstein breed. MenosRESUMEN.- El objetivo de este estudio consistió en un relevamiento de las principales enfermedades hereditarias BLAD, DUMPs y Citrulinemia,
