The addition of preservatives to the feed with action against bacteria and fungi prevents losses and the challenges caused by the excessive proliferation of these microorganisms in the feed, and, in turn, has a positive effect on the productive parameters.

The cimenol ring is a natural molecule derived from botanical extracts with properties as a microbicide, highly effective as a preservative of raw materials and finished food, whose synergistic combination with citric acid has bactericidal and fungicidal action against a wide variety of pathogenic microorganisms. This combination allows to make an effective replacement of organic acids and fungal inhibitors.

Trial: Cimenol ring in broilers against organic acids and fungal inhibitors

Experimental design

Objective:

To evaluate the effects on performance of a solution based on the combination of cimenol ring with citric acid on broilers compared to a combination of fungal inhibitors and organic acids.

Materials y methods

300 one-day-old male broilers (Vencobb 430) were distributed in 3 treatments and reared up to 35 days.

Treatment batches:

1. Negative control: standard basal diet (DBE)
2. AMN: DBE + Cimenol ring / citric acid combination at 1 kg / t continuously
3. OA + MI: DBE + organic acids 1 kg / t + mold inhibitors 0.5 kg / t (OA: sodium formate + sodium butyrate, MI: stabilized calcium propionate)

Note: DBE standard diet for broilers, without antimicrobials, growth promoters, coccidiostats or preservatives.

 Results

Weight and daily weight gain

Analyzing the results obtained, it is observed that the batch containing cimenol ring was the one with the highest daily weight gain and, consequently, the one with the highest final weight. The batch with cimenol ring compared to the control batch achieved 70 g more per bird and 14 g more per bird compared to the organic acid + fungal inhibitor batch.

Feed conversion rate

In relation to this parameter, no significant differences were observed, the feed conversion was good in all batches.

Survival and efficiency index

Survival was 4% higher in the supplemented batches, with 96%, while in the control batch it was 93%.

The batch that received cimenol ring and the batch supplemented with organic acids and fungal inhibitors had an efficiency index 25 points better than the control batch.

Conclusions

The combination of cimenol ring with citric acid obtains better results than those achieved by organic acids in combination with fungal inhibitors, since at a lower dose of 0.5 kg/t it achieves better weight (+14 g/bird, +0.57%), same survival, same efficiency ratio and conversion ratio. Every million broilers a farm would produce 14 more tons of meat.

The cimenol ring with citric acid can replace two products (organic acids and fungal inhibitors) thanks to its bactericidal and fungicidal capacity. It also allows to reduce the necessary product dose, giving more space to other ingredients in the formulation, reduce costs, improves handling and offers more extensive protection even in prolonged storage. Additionally, it is completely natural, it does not leave residue or create resistance. It is important to note that the combination of the cimenol ring and citric acid exerts a microbiocidal effect at the intestinal level, preventing digestive infections.

The cimenol ring combined with citric acid is a technology patented by Biovet S.A that is marketed under the name Alquermold® Natural.
