Think of this as DIY manual for the sheep farmer. Evidently, this is part of a series of books on animal husbandry. I am really curious on the TV aspect of this series. Perhaps this is an offshoot of an all-farm channel?
Of course, veterinary medicine ages, just as any science or health book. Having worked in a semi-rural area library, this type of material is often considered a core subject. Maybe a university library would think this is worth something, but public libraries can let this antique go.
