Why were more sheep than cattle found in New Mexico in the early years of Spanish settlement?

In the early years of Spanish settlement in New Mexico, more sheep than cattle were found primarily due to the region's arid climate and the suitability of sheep for grazing in such conditions. Sheep provided a reliable source of wool, meat, and milk, which were essential for the settlers' survival and economic needs. Additionally, the Spanish had a strong tradition of sheep herding, particularly from their experiences in the Iberian Peninsula, making sheep a more practical choice for early settlers.
