The effect of dietary conjugated linoleic acid on the production performance of gilts
The aim of this study was to evaluate whether the supplementation of conjugated linoleic acid (CLA) in feed mixtures influences the parameters of production performance in gilts. The experimental work was realized in operating conditions of a production pig farm. Total number of 40 gilts (20 gilts i...

The experimental work was realized in operating conditions of a production pig farm. Total number of 40 gilts (20 gilts in control group and 20 gilts in experimental group) of hybrid combination Czech Large White x Czech Landrace (CLW x CL) were included in the observation.
