R & S Cattle Farms

R & S Cattle Farms, a Wagyu breeder in Hilmar, CA, serves Merced County and the Central Valley near Modesto. The farm participates in national cattle associations and follows recommended health screenings for genetic soundness and disease prevention.

All breeding stock undergoes routine ultrasound for marbling and muscling, and replacement heifers are evaluated for temperament and structural soundness. The cows graze on open pasture and calves grow up in small groups with regular handling to support calm temperaments and robust health. Owner Roger Santos relies on sustainable grazing practices passed down through family traditions to maintain soil fertility and herd wellbeing.

Clean barns and well-maintained handling facilities reflect the farm’s daily commitment to animal comfort. A focus on balanced nutrition, pasture rotation, and gentle socialization helps cattle develop strong muscle structure and even temperaments. Seasonal shelter provision during heat or rain helps maintain herd resilience across changing conditions.
