Aims
- Evaluate the chemical composition of foods used in Animal Production
- Study the effect of diets based on pasture silage with addition of carbohydrates of diverse ruminal degradability on meat and milk quality.
- Contribute to the development of fast and reliable methods to evaluate silage quality by gas production kinetics.
- Develop a production system simulation model for ruminants fed on pastures and/or supplemented with pasture silage, of alfalfa base mainly.
- Evaluate the chemical composition of foods used in Animal Production.
- Participate in quality control inter-lab networks.
- Train undergraduate, graduate and postgraduate students.

Services
The Lab provides the following services to individuals, public or private institutions and business companies:
- Evaluation of food quality for ruminants and non-ruminants, nitrogen fractions and fat quality in raw milk.
- Participation in inter-lab control networks on the use of certain techniques. Training on their use.
- Analysis of volatile fat acids in ruminal fluids or silaged materials.
- Establishment of rations and diets for diverse animal production systems.
