Esta publicación no se puede considerar como un manual de Zoología en sentido estricto, debido a que se aborda el estudio de esta materia desde un punto de vista que busca la aplicación de los conocimientos. Los autores describen conceptos zoológicos básicos, junto a diferentes planteamientos prácticos de tipo zootécnico. El planteamiento zootécnico resulta un tanto peculiar, debido a que no se incluyen producciones animales muy conocidas, como pueden ser las que comprenden el ganado vacuno, porcino o caprino; muy conocidas y ampliamente tratadas en otros manuales. Nuestro enfoque se dirige hacia producciones poco usuales o regladas, como puede ser la lombricicultura o cría de lombrices de tierra y la apicultura.
