Techno-Economic Analysis of Innovative Phytogenic-Based Supplements for Ruminant Health and Productivity

The aim of this study was to evaluate the technical and economic impact of using commercial phytogenic feed supplements and dried Greek Oregano leaves as feed additives on dairy sheep farms. Fifteen farms in the Greek region of Thessaly were divided into intervention and control farms, and techno-economic data were collected before and after supplementation through structured interviews and cost analysis. The results showed that the administration of certain phytogenic supplements and oregano to ewes resulted in improved animal health, higher milk yield, and lower production costs, which created a positive trend in the financial results of the farm. Further research is needed to accurately determine the ideal production stage of the animals for the interventions, the amount of supplements administered, and the selection of appropriate plant species, which would lead to better financial management of the farms.
