The book "The influence of ferrosil and zeolite-containing additives on the metabolism and productivity of young laying hens" by Sergey Nikolaevich Abramov is a unique study that immerses the reader in the world of agriculture and poultry breeding. This work will be of interest not only to specialists in the field of agronomy and veterinary medicine, but also to everyone who seeks to understand how modern additives can change the approach to feeding and keeping poultry. Sergey Nikolayevich Abramov is a well-known scientist and practitioner, whose research in the field of zootechnics and animal feeding has been widely recognized. In his book, he shares the results of many years of experiments that show how ferrosil and zeolite-containing additives affect the metabolism of young laying hens. These additives are becoming increasingly popular in poultry farming due to their ability to improve poultry health, increase its productivity and, as a result, increase the economic efficiency of production. The book begins with an introduction to the topic, where the author explains why it is ferrosil and zeolites that are of interest to modern farmers. The reader will learn about the chemical properties of these additives, their role in metabolism, and how they can help in solving problems related to feeding and poultry health. This creates intrigue and paves the way for further in-depth study. One of the key themes of the book is the effect of supplements on the productivity of laying hens. Abramov cites data on how the use of these substances can increase egg production, improve the quality of eggs and even reduce the incidence among young animals. These aspects make the book particularly relevant for farmers who seek to optimize their production processes and improve profitability. The book will be useful not only for professional poultry farmers, but also for students of agronomic and veterinary faculties, as well as for anyone interested in modern methods of farming. It can be a valuable source of information for those who want to expand their knowledge of poultry feeding and maintenance, as well as for researchers working in related fields. Abramov's writing style is distinguished by scientific accuracy and accessibility. He skillfully combines complex scientific concepts with practical examples, which makes the material understandable even to readers who do not have a special education. The book is replete with graphs, tables and illustrations that help to better absorb the material presented and make reading more exciting. It should not be forgotten that Abramov’s work is part of a wider study in the field of zootechnics. His previous publications, such as “Modern Approaches to Poultry Feeding” and “Health and Productivity of laying hens”, are also noteworthy and can serve as an excellent addition to the study of the topic. If you are looking for information on how to improve the productivity of your farm, or want to learn about modern methods of feeding poultry, the book “The influence of ferrosil and zeolite-containing additives on the metabolism and productivity of young laying hens” will become an indispensable source of knowledge for you. It will not only enrich your arsenal of knowledge, but also inspire new experiments and discoveries in the world of poultry breeding.
