RESUMEN: El objetivo de este estudio fue optimizar un análisis mediante PCR en tiempo real con curvas de disociación para la detección confiable y económica del inserto mutante de 7,5 Kb del elemento transponible bovino BoERVK en el exón 5 del gen de la Apolipoproteína B (APOB), determinante de la deficiencia de colesterol - CD - (OMIA 001965-9913). Asimismo, aplicando esta técnica se realizó un cribado molecular preliminar para determinar la presencia de esta mutación en una muestra de ADN de vacas Holando (H) pertenecientes a seis tambos o fincas comerciales de diferentes regiones del Uruguay. A partir de la amplificación de los productos de PCR de 170 y 146 pb se logró distinguir claramente dos genotipos: homocigota (tipo silvestre wt/wt) y heterocigota (portador de la mutación CD: MUT/wt). El genotipo homocigota wt/wt fue detectado en la muestra representativa de 103 vacas H. Se concluye que el análisis mediante PCR en tiempo real con curvas de disociación es una técnica rápida, fácilmente interpretable, de bajo costo y altamente precisa para la detección de esta mutación, el cual puede ser implementado en programas de selección genética para evitar la propagación de la enfermedad en bovinos H. ------- ABSTRACT: The purpose of this study was to optimize a real-time PCR-melting analysis for reliable and economical detection of the 7.5 Kb mutant insert of the BoERVK bovine transposable element in exon 5 of the Apolipoprotein B (APOB) gene, which causes cholesterol deficiency - CD - (OMIA 001965-9913). This technique was also used to perform a preliminary molecular screening to detect this mutation in a DNA sample of Holstein Friesian cows (HFc) of six commercial dairy farms from different regions of Uruguay. By amplifying the 170 and 146 bp PCR products, two genotypes were clearly identified: homozygote (wild type wt/wt) and heterozygote (carrier of the CD mutation: MUT/wt). The homozygous wt/wt genotype was detected in the representative sample of 103 HFc. It is concluded that Real-Time PCR-melting analysis is a fast, easily interpretable, low cost, and highly accurate technique for detecting this mutation, which can be implemented in genetic selection programs to prevent the spread of the disease in HFc.

ABSTRACT: Despite the importance of dairy farming in Uruguay,little information on dairy systems in this country is available in the scientific literature, and management practices that influence calf welfare at the herd level have not been explored. The aims of this study were to
(1) describe the prepartum and calf-rearing systems, as well as the management practices that may influence calf welfare in pastured dairy herds in Uruguay, (2) estimate the annual calf mortality risk from birth to weaning, and (3) identify the primary clinical disease syndromes shown by the calves before death. A survey comprising a farm visit and a questionnaire was conducted on 225 randomly selected dairies with >30
milking cows, in 3 strata (31?99, 100?299, and ?300 milking cows) of 6 Uruguayan departments where dairies are concentrated. Retrospective information from July 2013 to June 2014 was collected. A descriptive analysis was performed and results were inferred into
the national dairy cattle population. Several management practices that could contribute to poor calf welfare were identified in a large proportion of farms. The annual calf mortality risk (calves that died between birth and weaning/calves born death or alive × 100,
n = 149 farms) was 15.2%. Age at weaning averaged 75 d. Farmers reported that the most common clinical syndromes were diarrhea and respiratory disease in 85.2% and 47.5% of the farms, respectively. There was no continuous veterinary advice in 61.3% of the farms, 20.0% lacked data records, 38.5% had poor drainage in the prepartum area with waterlogging after rainfall, 52.1% monitored the prepartum area ?2 times per day MenosABSTRACT: Despite the importance of dairy farming in Uruguay,little information on dairy systems in this country is available in the scientific literature, and management practices that influence calf welfare at the herd level have not been explored.
