Beef Cattle Production

Base Knowledge

This course unit directly coordinates with: Animal Nutrition and Feeding, Animal Reproduction, Animal Genetics and Breeding, Pastures and Forage Conservation, Animal Hygiene and Health

Teaching Methodologies

– Expository methodology for the presentation of theoretical concepts
– Monitoring of practical cases that illustrate the subjects presented and allow the perception by the students of the application of the concepts enunciated
– Analysis of articles, viewing of videos and case studies
– Contact with ESAC’s farm and others nearby.

Learning Results

Upon successful completion of the course unit, students should be able to:

  1. Understand the organization and operation of beef cattle production systems and their role within the national and European livestock sectors.

  2. Characterize beef cattle farms from a technical perspective, identifying the factors that influence productive, reproductive, and economic performance.

  3. Apply knowledge acquired in genetics, reproduction, nutrition, and animal health to the analysis and management of beef cattle production systems.

  4. Evaluate the suitability of breeds and crossbreeding strategies for different production objectives and farming conditions.

  5. Interpret technical and economic indicators used to monitor the efficiency of beef cattle enterprises.

  6. Relate management practices to animal performance, carcass quality, and product market value.

  7. Identify technical constraints within beef production systems and propose appropriate improvement strategies.

  8. Assess the technical, economic, and environmental sustainability of beef cattle production systems.
