Carter's Hay & Grain on Palm Row Drive in Lakeside has supplied equine feed, livestock nutrition, poultry rations, and pet food to East County San Diego's agricultural community since 1969. The store anchors the same Lakeside agricultural corridor that includes Hillikers Ranch on El Nopal, clustering farm-supply businesses along the Hwy 67 corridor near Lindo Lake County Park. Equine feed lines carry Purina, Hygain, and Integrity formulations alongside hay brokering for alfalfa, orchard grass, and timothy in bale quantities scaled from single-horse stalls to multi-head ranch operations. Veterinary nutrition recommendations from practices such as Lakeside Veterinary Hospital on Maine Avenue drive companion-animal food selections that include Fromm Family Pet Food and species-specific small-animal diets. The poultry department carries starter, grower, and layer rations from Purina and Modesto Milling alongside livestock health supplements from Animed and Durvet, supporting 4-H and FFA youth livestock projects throughout the Lakeside Rodeo season.
