Research shows that Anpario's Orego-Stim supports broiler performance during coccidial challenge

 

 

Research results revealed that the supplementation of Anpario's Orego-Stim in broilers infected with Eimeria maxima helped to mitigate the severe effects of coccidia cycling.

 

Dr. Matthew Jones, director of nutrition and veterinarian at the Southern Poultry Research Group (SPRG), presented the results at the 2022 Annual Poultry Science Association Meeting in San Antonio, Texas, the United States. The work is titled "Evaluation of a Phytogenic Compound, Orego-Stim, in Broiler Chickens During Eimeria maxima Challenge".

 

According to the results, broilers fed diets with Orego-Stim included had a significantly greater body weight gain and a numerically improved feed conversion ratio at 21 days of age compared to infected control birds. Additionally, the later cycling of coccidia was numerically lower in groups supplemented with the natural phytogenic, Orego-Stim.

 

"It is often this late cycling of coccidia that has the most negative impact on broiler performance," said Dr. Jones. "Whilst there is no question that early health issues can result in a lingering influence on performance, broilers have a tremendous capacity to compensate from such challenges and attain growth very close to breed standards. Later intestinal challenges though can have a far greater economic impact.

 

"This is because there is not the opportunity for compensational growth, and mortality near the end of production is related to far greater losses for the producer due to the feed and energy costs associated with raising these birds."

 

In the trial, 450 day-old male Ross chicks were assigned to one of five groups (negative control, challenge control, Orego-Stim: 600g/t, Orego-Stim: 800g/t and Orego-Stim: 1000g/t). On day eight, all birds, except the negative control, were individually challenged via oral gavage with E. maxima (75,000 oocysts per bird at 1ml dose per bird). Body weight gain, intestinal lesion scores, oocyst count and mortality were recorded until 28 days of age.

 

"At all inclusion rates, Orego-Stim was effective at supporting bird performance," explained Dr Jones. "Commercial poultry producers will have a coccidiosis programme in place and this may be a coccidiosis vaccine, a chemical, an ionophore or a combination of these. Natural alternatives, such as Orego-Stim, gives producers options to integrate these into their systems to take pressure off these traditional interventions.

 

"Orego-Stim is a natural solution which has potential for use within existing rotation or bioshuttle coccidiosis control programmes, as well as in programmes where late breaking coccidiosis is suspected."

 

Orego-Stim is a phytogenic feed additive formulated from a unique source of 100% natural oregano essential oil. It has been extensively researched and trialed in controlled challenge models and has been shown to successfully support broiler performance during coccidiosis challenge. It is available as both a liquid and powder, enabling flexibility in application for producers.
