Productive performance of Nilotic tilapia (Oreochromis niloticus) fingerlings fed a diet with pronutrients
Intestinal conditioner pronutrients are active molecules with a botanic origin that can optimize intestinal physiology, improving digestion and intestinal absorption.
Nilotic tilapia (Oreochromis niloticus) is a freshwater specie with a high interest in aquaculture, in fact, it is the fourth specie in terms of production worldwide, with 4200 thousand tons per year (SOFIA report, FAO 2018).
Evaluate the effects of intestinal conditioner pronutrients supplementation in diets of Nilotic tilapia (Oreochromis niloticus) fingerlings by assessing productive parameters in a recirculating system.
Material and methods
The assay was carried out in the Universidad Científica del Sur (UCSUR), in Lima, Peru. Fingerlings, with a weight average of 0.9 grams, were taken from the Centro de Investigación Piscícola de la Facultad de Pesquería de la Universidad Nacional Agraria La Molina.
- Control diet: 0 g/kg of pronutrients
- Experimental diet: 10 g/kg of pronutrients
They were made 4 replicates per each treatment, using 15 fingerlings per replicate. Feed was ad-libitum during the 70 days of the assay. Temperature, mortality, water quality and feed, were checked daily, and diet remnants were removed.
Environmental parameters during the assay:
The experimental diet achieved an improvement of FCR of 9% and an increase of 3% of the specific growth rate, in comparison with the control diet.
The growth improvement was shown after the 30 day of treatment. Based on the study we can affirm that there is an optimal age and size to administer pronutrients.
Diets including intestinal conditioner pronutrients improve the feed conversion rate (FCR) by 9% during fingerling stage. Intestinal conditioner pronutrients are commercialized under the name of Alquernat Nebsui, by Biovet S.A.
