Hardcover. Condizione: Very Good. First Edition. "Professor Jan C. Bonsma is known internationally for his knowledge of livestock ecology. During his recent year as a visiting professor [at Texas A&M University] he impressed cattlemen most with his visual appraisal of cattle for functional efficiency.

His high degree of accuracy convinced most observers that animals with low fertility could be identified visually." - Preface. [8], 93 glossy pages. Twenty-one black and white illustrations.
