Evaluación de las características de tipo y producción en ganado holstein del criadero Pacaguan

Abstract

The “evaluation of the type and production characteristics in Holstein cattle was carried out in the “Pacaguan Farm”, located in Penipe canton, Quimiag Parish, the Candelaria sector, the experimental units were constituted by 60 animals, in the production stage, to Hypothesis testing and data tabulation were calculated using descriptive statistics and correlation coefficient. Therefore, the results indicated that the “Pacaguan” farm, when evaluating the characteristics in the cows in production, it was observed that for the location of the variables of previous nipples, locomotion, position as femoral, length of nipples, angle of hooves, posterior legs lateral view, udder depth, and inclination, high values were reached with 4.48, 7.07, 5.28, 5.35, 5.12, 5.32, 5.67, 4.67, points respectively, in terms of the assessment of the lowest data were found in insertion anterior udder, posterior udder height and rear udder width with 5.90, 5.72, 4.47 points in the order mentioned above. In the type-production correlation, the characteristics that most influence it are the inclination of the udder with a bilateral significance of 0.932, which identifies a high positive relationship while for the width of the rump the value of significance was 0.224, that is to say, low positive relationship. Concluding that bulls with high rates of udder components should be used as one of the negative criteria in the herd average, the presence of these characteristics with high values is fundamental in the production of the herd. It is essential to keep in the herd functional cows that stop once a year, healthy and for this, it is essential to select bulls for artificial insemination that combine with the characteristics of production, longevity, and type.
