SPECIAL STORY 42 FEED & ADDITIVE MAGAZINE February 2021 The efficacy of these pronutrients has been widely proven in multiple trials following the scientific method in farms from all around the world with different species (poultry, pigs, aquaculture). The following charts summarize results obtained in a commercial broiler farm where AGPs were replaced by intestinal conditioning pronutrients. They prove that AGPs can be completely withdrawn thanks to using pronutrients, as they can reach better performance results: in this farm, one million broilers with pronutrients would produce 370 more tons of meat and save 374 tons of feed. In layers and breeders, intestinal conditioners also help to improve the laying rate (+6%), egg internal quality (+8.4%) and egg weight (+5.2 g). In conclusion The intensification of animal husbandry led to using commercial diets that do not include molecules of botanical origin that are necessary for the proper functioning of the organs. For this reason, substances such antibiotic growth promoters (AGPs) were included in the diets to maintain digestive health. The use of these products, though, led to the development of microbial resistances and there is a need to withdraw them from feed. Reconnecting with nature is the best way to maintain performance and animal health without AGPs: pronutrients are molecules from plant extracts that recover animal’s natural strength and improve productive performance. Intestinal conditioner pronutrients are the ones that improve the status of the gut mucosa, and therefore have a positive effect on growth rate, feed conversion, the laying rate, and egg quality. Besides, they are a broadly studied natural tool effective to improve performance without resistances, residues, and withdrawal periods. The use of these molecules was studied and developed by Biovet S.A. and are marketed under the name Alquernat Nebsui.
