The purpose of this trial, performed in Colombia in 2017, was to assess the effect of removing antibiotic growth promoters in pigs during the withdrawal period (30 days) at the end of the fattening stage and replacing them by intestinal conditioner pronutrients.

Experimental design

Data was obtained from a total of 134.956 pigs, separated into two batches:

– TREATMENT BATCH (49.439 animals): Fed with basal diet and an intestinal conditioner at a dose of 0,5 kg/Tn.

– CONTROL BATCH (85.517): Fed only with basal diet.

Results

Batch treated with intestinal conditioner pronutrients had reduced feed intake, obtaining a higher final weight, which improved the conversion rate regarding to the control batch. Mortality was also slightly reduced in the treated batch.

Conclusions

The intestinal conditioner pronutrients allowed to improve productive parameters thanks to a better intestinal health, which increased the use of feed and enhanced the intestinal epithelium defensive barrier to control the growth of enteric pathogens.

This product, based on intestinal conditioner pronutrients, is commercially available under the name of Alquernat Nebsui.
