Reproduction of Feral Goats on Santa Catalina Island, California

Abstract

Reproduction of Feral Goats on Santa Catalina Island, California by Bruce E. Coblentz. Bull. Southern California Acad. Sci., 8 1(3): 128-1 37, 1982. Natality of feral goats on Santa Catalina Island appeared to be a density-dependent response to forage quality and quantity. Conception rates ranged from 1.11 corpora lutea/pregnancy in a poor forage area to 1.80 corpora lutea/pregnancy in a good forage area. Body weight, dressed weight, hind foot length, horn length, and kidney fat index of goats from the good forage area were significantly greater (P < 0.05) than those from the poor forage area. Partial control of goats on the island increased natality; total removal of feral goats was recommended.
