Even before the outbreak of the recent pandemic, poultry production worldwide has been facing challenges such as the reduction of antibiotics, alternative means of production and operational productivity. These are our future tasks which we must not lose sight of. Consumers today are better informed and consequently demand more transparency and greater responsibility in establishing forms of husbandry that promote antibiotic reduction and animal welfare.
Dr. Eckel’s highly effective feed additive Anta®Phyt helps producers and manufacturers in achieving their goals. With its phytogenic ingredients including medical plants as , Anta®Phyt supports a healthy gut flora and has antibacterial effects, especially against gram positive bacteria.
A broiler feeding test, which compared Anta®Phyt with feed groups with and without antibiotic growth promoters (AGPs), showed that the phytogenic feed additive has significant benefits over AGPs in terms of feed efficiency, performance and animal health.
Reducing antibiotic growth promoters (AGPs) is a key factor in increasing the sustainability of broiler production. A suitable AGP replacement should protect animals from negative effects and improve the health of the digestive system. Effective phytogenic feed additives can achieve this. The effect of the phytogenic feed additive Anta®Phyt MO on the performance and gut health of broilers infected with Eimeria spp. was investigated in this study. The aim was to demonstrate the impact of the phytogenic additive in comparison to a negative control (NC) group and a positive control (PC) group with an AGP programme during the induced dysbiosis.
Materials and methods
A total of 1,020 one-day old broiler chicks (ROSS 308) were randomly divided into three dietary treatment groups. All birds were fed in two nutritional phases (starter: 1–21 d and grower: 22–40 d) with a maize-soybean-meal-based diet in mash form. , while AGPs were included in the diet of one PC group. The other PC group received a phytogenic feed additive (NC + 300 g/t Anta®Phyt MO, Dr. Eckel Animal Nutrition GmbH & Co. KG). Each group comprised 340 birds.
On day 14, all birds were infected with a vaccinal strain of Eimeria spp. The pathogens were administered orally in the drinking water. The associated infections and intestinal immune response were assessed in terms of performance (21 d and 40 d) and gut health factors (21 d). The one-way ANOVA was used for statistical analysis.
The daily weight gain in the phytogenic group was significantly higher than that in the PC group over the 40-day trial. Additionally, a better FCR was observed and the mortality was lower in comparison to the NC and PC groups (Fig. 1).

The improvement in performance results in an enhanced European Production Efficiency Factor (EPEF) in the group receiving Anta®Phyt MO (458) compared to the NC (445) and PC (438) groups. In terms of intestinal health, birds receiving the phytogenic additive had numerically longer intestines compared to the NC and PC groups (Fig. 2).

Discussion and conclusion
Anta®Phyt MO increases broiler performance during Eimeria spp. infection. The phytogenic feed additive shows better effects than an AGP programme in terms of weight gain, FCR, mortality and gut health.
