Armstrong Ranch Inc

Armstrong Ranch Inc raises Simmental cattle in Lander, WY, in the Wind River Valley near Casper. For more than twenty years the ranch has followed guidelines set by leading cattle associations and industry-recommended genetic and health screenings, including calving-ease evaluations and herd fertility testing as part of its approach to responsible breeding.

Calves spend their first months on open pastures and in family-run barns for early socialization, while rotating grazing practices support pasture health and biodiversity. During winter months the herd is housed in well-ventilated sheds with straw bedding, and a nutrition plan tailored to each growth stage helps maintain herd vitality.

This multi-generational operation has produced cattle noted for balanced muscling and calm temperaments by visitors. Selective use of embryo transfer and careful lineage tracking helps maintain robust adaptability across Wyoming’s seasonal swings. Reviewers often mention steady weight gains, easy handling, and proven performance under varied conditions.
