The growing problem of antibiotic resistance calls into question practices related to the use of antibiotics. Their large-scale use to accelerate the rapid growth of food animals is of increasing concern to researchers. Currently, several studies are being carried out to find biological solutions as an alternative to the use of antibiotics in poultry farm. It is within this framework that the present study falls, the objective of which is to evaluate the effectiveness of an organic product, ALPHA-BIO+, on the production parameters of Lohmann Brown laying hens. Thus, two batches (control and experimental) subdivided into triplicate were formed from a sample of 458 animals. Thus, a classic breeding protocol with the use of antibiotics was applied in the control batches. As for the experimental batches, they received the food additive ALPHA-BIO+. The technical data obtained were subjected to statistical analyzes in order to assess the effectiveness of ALPHA-BIO+ on the animals zootechnical parameters. Indeed, in terms of ingested food, the values ​​obtained varied from 97.7 to 120.87 g for the control batch and from 94.12 to 114.95 g for the experimental batch. Regarding the laying rate, the two batches reached peak laying between the 30th and 32nd weeks of age with 95.24% for the control batch and 98.54% for the experimental batch. However, the conversion indices did not show a significant difference between the two batches. According to the results, the food additive ALPHA-BIO+ could help reduce the use of antibiotics in poultry farms.
