Coccidiosis is a parasitical disease caused by different species of Eimeria. These parasites reproduce inside of the enterocytes causing serious intestinal alterations. It is a widely spread disease that generates large economic losses worldwide.

Intestinal optimizer pronutrients stimulate the local immunity of the gut, improving the ability of the intestinal immunity to break the cycle of coccidia by avoiding their multiplication.

1. Objective

Evaluate the effect of intestinal optimizer pronutrients in broilers infected with different species of Eimeria.

2. Material and methods

960 broilers were divided into 32 sheds, with a total of 30 animals per shed. The animals were infected at two weeks of age with oocysts of: Eimeria tenella, E. acervulina, E. maxima and E. necatrix

Four treatments were established:

• T1-Negative Control: no infection or treatment
• T2-Positive Control: infected without treatment
• T3-Experimental treatment A: intestinal optimizer pronutrients at doses of 0.5 kg/t from day 0 to slaughter
• T4-Experimental treatment B: intestinal optimizer pronutrients at doses of 1 kg/t from day 0 to slaughter

Feed intake, average daily gain and food conversion rate were assessed.

3. Results

• Feed intake

Two weeks from the experimental infection, statistically significant differences in feed intake were observed between positive control and experimental treatments.

• Average daily gain

In relation to the average daily gain there was a significant increase associated with the administration of the pronutrients. In this case, the effect was dose dependent, as there was a higher average daily gain when adding a higher amount of pronutrients.

• Conversion rate

The conversion rate was lower in groups treated with pronutrients, obtaining a value even lower than negative control, the group without artificial infection. In this case as with the average daily gain, a dose-effect ratio is observed, obtaining a better result by increasing the dose of pronutrients.

Conclusion

The use of intestinal optimizer pronutrients improves productive parameters, such as feed intake, average daily gain and conversion rate of artificially infected birds with different species of Eimeria.

Intestinal optimizer pronutrients are marketed under the name Alquernat Zycox from Biovet S.A.
