    Altres ajuts: CERCA Programme/Generalitat de Catalunya.Inbreeding and effective population size (Ne) are fundamental indicators for the management and conservation of genetic diversity in populations. Genomic inbreeding gives accurate estimates of inbreeding, and the Ne determines the rate of the loss of genetic variation. The objective of this work was to study the distribution of runs of homozygosity (ROHs) in order to estimate genomic inbreeding (FROH) and an effective population size using 38,789 Single Nucleotide Polymorphisms (SNPs) from the Illumina Bovine 50K BeadChip in 86 samples from populations of Charolais de Cuba (n = 40) cattle and to compare this information with French (n = 20) and British Charolais (n = 26) populations. In the Cuban, French, and British Charolais populations, the average estimated genomic inbreeding values using the FROH statistics were 5.7%, 3.4%, and 4%, respectively. The dispersion measured by variation coefficient was high at 43.9%, 37.0%, and 54.2%, respectively. The effective population size experienced a very similar decline during the last century in Charolais de Cuba (from 139 to 23 individuals), in French Charolais (from 142 to 12), and in British Charolais (from 145 to 14) for the ~20 last generations. However, the high variability found in the ROH indicators and FROH reveals an opportunity for maintaining the genetic diversity of this breed with an adequate mating strategy, which can be favored with the use of molecular markers. Moreover, the detected ROH were compared to previous results obtained on the detection of signatures of selection in the same breed. Some of the observed signatures were confirmed by the ROHs, emphasizing the process of adaptation to tropical climate experienced by the Charolais de Cuba population

    Whole-genome sequencing reveals insights into the adaptation of French Charolais cattle to Cuban tropical conditions

    In the early 20th century, Cuban farmers imported Charolais cattle (CHFR) directly from France. These animals are now known as Chacuba (CHCU) and have become adapted to the rough environmental tropical conditions in Cuba. These conditions include long periods of drought and food shortage with extreme temperatures that European taurine cattle have difficulty coping with. In this study, we used whole-genome sequence data from 12 CHCU individuals together with 60 whole-genome sequences from six additional taurine, indicus and crossed breeds to estimate the genetic diversity, structure and accurate ancestral origin of the CHCU animals. Although CHCU animals are assumed to form a closed population, the results of our admixture analysis indicate a limited introgression of Bos indicus. We used the extended haplotype homozygosity (EHH) approach to identify regions in the genome that may have had an important role in the adaptation of CHCU to tropical conditions. Putative selection events occurred in genomic regions with a high proportion of Bos indicus, but they were not sufficient to explain adaptation of CHCU to tropical conditions by Bos indicus introgression only. EHH suggested signals of potential adaptation in genomic windows that include genes of taurine origin involved in thermogenesis (ATP9A, GABBR1, PGR, PTPN1 and UCP1) and hair development (CCHCR1 and CDSN). Within these genes, we identified single nucleotide polymorphisms (SNPs) that may have a functional impact and contribute to some of the observed phenotypic differences between CHCU and CHFR animals. Whole-genome data confirm that CHCU cattle are closely related to Charolais from France (CHFR) and Canada, but also reveal a limited introgression of Bos indicus genes in CHCU. We observed possible signals of recent adaptation to tropical conditions between CHCU and CHFR founder populations, which were largely independent of the Bos indicus introgression. Finally, we report candidate genes and variants that may have a functional impact and explain some of the phenotypic differences observed between CHCU and CHFR cattle

    El Examen Estatal es una de las forma de culminación de estudio en la Carrera Medicina Veterinaria y Zootecnia, aplicado desde el curso escolar 1982-1983 y surgió como resultado del perfeccionamiento continúo de los planes y programas en el Ministerio de Educación Superior Cubano, requiriéndose de métodos estadísticos para evaluar su calidad, considerando el índice académico de los estudiantes. La investigación se desarrolló en la Universidad de Granma, con una muestra de cinco cohortes del plan de estudio “C” perfeccionado y una del plan “D” con 553 estudiantes. Se determinaron las medias de la calidad de las calificaciones de los exámenes estatales y del índice académico. Los datos se obtuvieron de los registros de calificaciones que custodia la secretaría docente de la facultad. Para el análisis estadístico del índice académico de cada cohorte se utilizó la comparación de medias y la calidad se evaluó a través de Ji-cuadrada, el nivel de significación se estableció para , ambas pruebas se desarrollaron en el sistema estadístico Stagraphics Plus versión 5.1. El promedio general del índice académico fue 4,07, los graduados en el curso 2004-2005 mostraron resultados significativamente superiores en este indicador. Las cohortes de los graduados en los cursos 2004-2005 y 2011-2012 obtuvieron los valores de calidad más altos del Examen Estatal, correspondientes a los planes de estudio “C” perfeccionado y “D” respectivamente, siendo superior el último, sin diferencia significativa entre ellos. Se concluye que las cohortes investigadas reflejan buenos resultados en los índices académicos y en la calidad del Examen Estatal.PALABRAS CLAVE: Examen Estatal; culminación de estudio; calidad; Medicina Veterinaria.ANALYSIS OF THE AVERAGE GRADE AND THE QUALITY OF THE STATE OWNED EXAM OF THE STUDENT'S GRADUATES DURING TWO STUDIES'S PLANABSTRACTThe state examination is the form of culmination of study in the career Veterinary Medicine and Zootechny, that it is applied from 1982-1983 and it springs up as a result of the perfecting it continues of the plains and programs in the Superior Ministry of Education. The investigation develops in Veterinary Medicine´s career at Granma´s University. With five cohorts´s sign of the curriculum perfected “C” and one of the plan “D” with 553 students. It was determined the median of the quality of the grades of the Statal Exams and the average grade. The data got from the records of the Teaching Secretary´s office of the Faculty. The 40 % of the students graduated in the last edition had an interview in order to know the satisfaction with the procedure of the exercise of the culmination of the study. A graphic analysis of medians was utilized for statistical analysis and the quality was evaluated through Ji´s test squared, the level of significance became established for p<0, 05, both test were developed in the system of the statistical analysis Stagraphics Plus version 5.1. The academic index mediates of 4, 07 and the graduates in the course 2004-2005 showed significantly superior results in this indicator. The cohorts graduated in the courses 2004-2005 and 2011 – 2012 achieved the more high results in the quality of the state examination and they correspond to the plain of the study “C” and “D” respectively, by being superior the last one, without significant difference among them. It concludes that the application of the plain “D” perfecting still has not represented significant changes in the behavior of the academic index and the quality of the State Examination. The average index of 4.07 reflects good proven to be academic in the exercise of the culmination of studies, this indicator does not differ significantly from the median, except at the course 04-05, that sign better proven to be significantly different. Better results of quality get in the graduate students of the course 04-05, Plan perfected “C” , and the graduate students of the course 2011-2012, Plan “D” , superior in this last, although does not differ significantly. It is been understood that the investigated cohorts gave good results in the rate academic of graduates and in the quality of the State-owned exam.KEYWORDS: State-owned exam; culmination of study; quality; Veterinary Medicine
