Abstract

The objective of the study was to investigate the effect of organic acids supplementation on growth performance of crossbred pigs from Landrace sire and Yorkshire dam. A total of 120 weaned piglets at the age of 21 days were randomly allocated to 4 treatments. In each treatment, there were 3 replications with 10 pigs per replication.
DC was Control (with basal diet). TN1, TN2 and TN3 were basal diet supplemented with organic acids at the levels of 2 kg, 3 kg and 4 kg/ ton of feed, respectively. The pigs were weighed at 21, 30, 60, 90, 120 and 150 days of age to calculate body weight (BW) and average daily gain (ADG). The supply and rest feed were recorded daily to calculate average daily feed intake (ADFI) and feed conversion ratio (FCR). The results showed that, organic acids supplementation in feed from 21 to 120 days of age improved BW and ADG but not ADFI or FCR in pigs.
