Factores de transformación para el cálculo de la biomasa consumida por Gineta (Genetta genetta) y Meloncillo (Herpestes ichneumon) (Carnivora, Mammalia)

Abstract

Correction factors to estirnate consumed biomass by Genets (Genetta genetta) and Egyptian Mongooses (Herpestes ichneumon) (Carnivora, Mamnzalia)
Feeding tests were conducted to relate fresh consumed biomass with dry excreted biomass by one adult male Genet Genetta genetta, and one adult male Mongoose Herpestes ichneumon. Correction factors for Genet and Mongoose, by which the excreted dry weight should be multiplied for each group of prey, are: srnall mammals, 9.0 and 12.1; rabbits, 18.0 and 6.9; small birds, 7.5 and 13.7; middle size birds, 15.7 and 9.1; fowl, 45.0 (Genet); reptils, 10.0 and 29.5; arnphibians 24.0 (Genet); crustaceans, 10.0 (Genet); carrion, 42.0 and 55.3; eggs, 45.0 (Mongoose). These correction factors are smaller than those obtained by other authors with the same prey types when studying other carnivore species, but the method of this work is also different, since dry faeces were wheighed before washing them.
