Optimal dietary amino acid levels for pigs

Project Details


Main research question/goal
Weaned piglets and fattening pigs are fed a compound feed. Each ingredient  contains a different amount of amino acids. The total amount of amino acids and the ratio between them affects the growth performance of the animals. This project examines in detail the interactions between amino acids and amino acid requirements in piglets and fattening pigs. The aim is to determine optimal nutrient requirements, while taking the gender and the age of the animals into account.

Research approach
The Animal Sciences Unit carries out performance trials with piglets and fattening pigs. Several amino acid levels are provided to the animals, then their growth performance (daily gain, feed conversion, carcass quality) is measured. Recording the quantities and composition of the ingested feed and measuring the daily growth are prerequisites for the correct analysis of the results.

The pig industry is currently characterized by fluctuating food prices and low prices for the carcasses. This situation threatens the profitability of pig farming. Better knowledge of the amino acid requirements of piglets, growing and finishing pigs leads to greater accuracy of the feed composition, which benefits performance and reduces the emission of nutrients.
