Paśu Ayurveda, an ancient Bharatiya science, meticulously studied the physical traits of animals to determine their auspiciousness or inauspiciousness, deeply rooted in texts like Varähamihira's Brhat Samhitä and Kautilya's Arthaśästra. This practice reflected the belief that animals influenced human prosperity, guiding breeding and selection practices that emphasized the close relationship between humans and animals in ancient Bharat. Domesticated animals, such as cows, horses and dogs, were revered not just for their practical uses but as symbols of fortune, with specific physical characteristics linked to prosperity and well-being. Cattle were central to this study, with auspicious traits like large testicles and specific colorations considered indicators of strength and fertility. The Brhat Samhitä also classified other animals, including dogs, elephants and birds, highlighting their roles in society and governance. Kauțilya's Arthaśāstra complemented this by providing practical guidelines for animal management, illustrating a sophisticated understanding of animal science and its significance in daily life.
