The book "Physiology of farm animals" by Konstantin Rafailovich Viktorov and E. N. Pavlovsky is a unique teaching aid that will become an indispensable assistant for students of zootechnical and veterinary institutes, as well as for anyone interested in the physiology and health of agricultural animals. This publication not only covers a wide range of topics related to animal physiology, but also focuses on the practical application of knowledge in real life. Animal physiology is a science that studies the functions and processes that occur in animals that are important for agriculture. The book discusses in detail such aspects as metabolism, reproductive functions, features of growth and development, as well as the impact of the external environment on animal health and productivity. The authors seek to explain complex biological processes in simple and accessible language, which makes the material understandable even for those who are just starting their way in this area. The book will be of interest not only to students, but also to practicing veterinarians, zootechnicians and everyone who works with animals. It can be an excellent guide for farmers who want to increase the productivity of their animals and improve their living conditions. Given the urgency of issues related to animal husbandry and veterinary medicine, this manual will be useful for those who are simply interested in the topic of animal health and welfare. The topics raised in the book cover critical aspects, such as the physiology of digestion, respiration, circulation, and the nervous system. The authors focus on how these processes affect animal productivity and health, which makes the material particularly relevant in light of current challenges in agriculture. For example, in the face of climate change and increasing demands on product quality, understanding physiological processes is becoming key to successful farming. The style of the authors is distinguished by scientific rigor, but at the same time it retains accessibility and intelligibility. Viktorov and Pavlovsky use many examples from practice, which allows the reader to better absorb the material and see its application in real life. Their previous work has also received recognition in academia, and this manual continues the tradition of qualitative and in-depth analysis of physiological processes. The book "Physiology of farm animals" can become the basis for further study and in-depth understanding of animal physiology. It is ideal for those who want not only to gain theoretical knowledge, but also to learn how to apply them in practice. Readers interested in topics such as veterinary medicine, zootechnics, agronomy and ecology will find much useful information in this manual. If you are looking for a tutorial that will help you understand the complex issues of animal physiology and their impact on productivity, then this publication will be an excellent choice. It will not only expand your knowledge, but also inspire new research and practical achievements in the field of agriculture. Do not miss the opportunity to immerse yourself in the fascinating world of the physiology of farm animals along with the book by Viktorov and Pavlovsky!
