Gex, a town near Geneva, has seen a revival in its dairy sector, thanks in part to the efforts of young farmers like Arnaud Josserand. Ten years ago, the area's dairy industry was in decline, but Arnaud, who took over his family's farm in 2016, has been working to restore it. His farm, located near the Jura foothills, produces 550,000 liters of milk annually on 110 hectares of land, 70 of which are dedicated to grassland. With the help of his breeding advisor, Hervé Balanche, Arnaud has improved herd management and animal welfare, focusing on a balance between economic efficiency and workload. Last year, he installed a milking robot to streamline operations and reduce labor. Arnaud's journey began in Canada, where he completed a one-year internship after earning his BTS Acse, a French vocational qualification. It was there that he realized how much he missed working with dairy cows. Returning to France, he decided to settle in Gex, where the family farm had been managed by his father and a non-family partner. The dairy herd had been neglected in favor of crops, and the dozen Montbéliardes, a breed of dairy cows, were not productive. After the partner left, Arnaud took over, re-enrolling the herd in dairy control and introducing new techniques such as calf genotyping, sexed seeds, and a dynamic rotational grazing system. These changes improved milk quality and increased production. Over the past seven years, the herd size grew from 30 to 50 cows, and milk output per cow doubled from 19 to 36 liters per day. The improvements in milk quality allowed Arnaud to recover a bonus of 15 euros per 1,000 liters. He credits his success to the support of his advisor and his father, who gave him the freedom to implement his ideas. Investments in the farm, totaling 170,000 euros, improved animal comfort and production conditions, including expanding stables, installing windbreak nets, and upgrading feeding systems. In 2025, Arnaud decided to automate milking with a new stall purchased for 175,000 euros. This move helped maintain production despite challenges such as grazing difficulties due to drought and heat. While the grazing plan for 2026 did not fully succeed, the milking robot has proven effective, saving two hours of work per day and improving productivity. Arnaud is now considering hiring additional help and implementing further improvements, including new soil working methods to ensure the sustainability of his farm for future generations.
