Acompañamiento técnico en la cría de terneras de las razas Holstein y Guernsey en la finca Juncalito perteneciente al Municipio de Zipaquirá.

Abstract

The present work was carried out at Juncalito farm, located in the municipality of Zipaquirá, with a herd of cows for dairy production. Among the breeds, the Holstein breed stood out due to its excellent production, higher economic return on feed costs, unmatched genetic merit, and great flexibility in various environmental conditions. Another breed found in this production system is the Guernsey breed; this breed is known for producing dairy with high fat and protein content, as well as a high concentration of beta-carotene. Despite being of intermediate size, Guernsey cows consume less forage but produce a greater quantity of milk compared to other animals. The objective of this work was to provide technical support in the nutrition of calves from both breeding and raising of the mentioned breeds. The process began with a diagnosis of the farm, collecting initial data to make informed decisions regarding the breeding and health management of the animals. Using selected calves from birth as the baseline population, a nutritional balance was performed, considering colostrum, milk supply, concentrated diet, and supplementation with forages (grass and hay). Following this intervention, improvements were observed in daily weight gain (GPD) and the overall well-being of the calves, as evidenced by adherence to the 5 freedoms.
