Use of white sweet lupin seed (Lupinus albus var. AMIGA) in a diet for pig fattening

Summary

An experiment with 36 fattening pigs was conducted to evaluate the use of locally produced white sweet lupins (Lupinus albus var. AMIGA).

Starting with a common diet for fattening pigs, soybean meal and grain were substituted by 10 % or 20 % white lupins. There was no supplementation of diets with synthetic amino acids.

The use of 10 % lupin seed had no influence on fattening performance, whereas 20 % decreased feed consumption and daily.weight gain. With the increasing level of lupins, digestibility of crude protein and organic matter decreased.

Slaughtering performance and meat quality were not affected, only fatty acid composition of back fat changed. The percentage of linoleic and linolenic acids were increased.

Owing to the results of the present experiment, diet for fattening pigs could include white sweet lupins up to 10 % with no adverse effects on performance data.
