Pronutrients and productive parameters in broilers
Study conducted in 2018 in Antioquia (Colombia) with intestinal optimizer pronutrients and intestinal conditioner pronutrients
In 2018, a study conducted in Antioquia region (Colombia) evaluate the effects of intestinal optimizer pronutrients and intestinal conditioner pronutrients, administered from day 21stÂ to 40thÂ of the production cycle, on productive parameters.
MATERIALS AND METHODS
Data from a total of 66.300 animals separated in two batches were analyzed:
- TREATMENT BATCH (35.700 animals): Pronutrients were administered at a dose of 0,5 kg/ton of feed of each type:
- Intestinal optimizer pronutrients: from day 21stÂ to 40th.
- Intestinal conditioner pronutrients: from day 30thÂ to 40th.
- CONTROL BATCH (30.600 animals): Fed with a basal diet.
From day 21stÂ until day 30th, in the TREATMENT BATCH, intestinal optimizer pronutrients were administered “ON TOP”, together with coccidiostats.
From day 30thÂ until day 40th,Â both the chemical coccidiostats and antibiotic growth promoters were removed.
Intestinal optimizer pronutrients were maintained in the diet as an alternative to coccidiostats, and intestinal conditioner pronutrients were added (days 30thÂ to 40th) as an alternative to the antibiotic growth promoters.

CONCLUSIONS AT THE END OF THE TRIAL
- The high cumulative mortality shown in table 2 is due to the poor initial quality of the chicks in the treatment batch, which, as shown in graph 3, produces a very unequal mortality between the two batches in the first 3 weeks of the study, which are the previous ones to the beginning of the treatment with pronutrients.
- Partial mortality since the beginning of treatment (day 21) is only 0,65% higher in the batch treated with pronutrients, considering that this batch also starts with a mortality 0,33% higher than the control.
Graph 3: Dynamics of mortality
- We can conclude that the treatment with intestinal optimizer and conditioner pronutrients allows a reduction of the initial mortality and the recovery of the rhythm of growth, obtaining similar results to those of the control batch, because it obtains a minimum weight difference with a lower consumption, which results in a slightly improved feed conversion rate and efficiency (0,04 and 2,0 points respectively) in the batch treated with pronutrients.
