The trial was conducted in Romania beetwen 2017 and 2018 with Isa Brown laying hens, and was aimed at preventing coccidiosis and minimizing economic losses related to the disease through the use of an intestinal optimizer.
An intestinal optimizer is a product of natural origin rich in pronutrients that improves the local immune response of the intestine. It is not a pharmacological product, it does not create resistances, it does not leave residues and, therefore, it can be administered during the whole productive cycle without withdrawal period, unlike chemical coccidiostats.
The trial was conducted in a farm that suffered outbreaks of coccidiosis by E. tenella for 6 years in 22-28 weeks-old hens.
The birds were separated into two batches:
The evaluated parameters were: weekly and accumulated egg production (%) (Housed Hen Egg), presence of coccidiosis lesions and weekly and accumulated mortality rate.
Regarding egg production (%), the batch using the intestinal optimizer as preventive treatment shows a normal egg production (not affected by the disease) that even exceeds the breed standard (Chart 1). In contrast, in the control batch, which suffers the coccidiosis outbreak, production is affected and the batch is not able to recover normal parameters (Chart 2). The same situation can be observed if the number of housed hen eggs (H.H.E.) of both bathes are compared (Chart 3).
Regarding mortality, the peak produced by cecal coccidiosis due to E. tenella in the control group can be seen in figure 4. The outbreak caused fibrino-necrotic or hemorrhagic lesions with a score of 3 to 5.
Chart 5 shows a summary of the productive parameters evaluated and the difference between the studied batches.
To conclude, the use of an intestinal optimizer in a batch as a preventive for coccidiosis:
Therefore, this trial shows that using an intestinal optimizer for the prevention of coccidiosis is an effective tool to prevent the outbreak of the disease whilst allowing good productive results. However, according to the obtained results, its use once symptoms appear does not have the same effectivity and the productive parameters expected for the age of the animal are not met.
This optimizer of the intestinal mucosa is commercially available under the trademark Alquernat Zycox.
