Object of study: digestion and justification Humilid for ostriches in a critical period of growth. The purpose of research - to find out the features of the physiological state of the digestive system ostriches ontogeny of 3 to 60 days, and against the background of the use of feed additive "Humilid". Research Methods: clinical (heart rate, BF), biochemical (the content of total protein, protein fractions, creatinine, alkaline phosphatase, the activity of digestive enzymes), microbiological, histological, zootechnical (growth dynamics, growth rate), statistical (probability the results). Scientific novelty: For the first time established features of formation of the enzyme system ostriches the level of activity of various digestive enzymes digestive canal during growth of output and 60 days and their role in the breakdown of proteins, lipids, carbohydrates and fiber. For the first time the parameters amylase activity, proteolytic, lipolytic, cellulolytic enzymes and their distribution in different locales alimentary canal ostriches at different stages of growth and development. Theoretically grounded and practically proved the feasibility of using biologically active food additive "Humilid" to improve the adaptive capacity of the body ostriches during the growth of from 3 to 60 days and increasing hydrolytic processes in different parts of the gastrointestinal tract. This indicates high activity of amylase enzymes in the duodenum, proteolytic and lipolytic - in empty and ileum, cellulolytic - in the cecum. Established Humilid activating effect on the functional state of the digestive system and indicators of homeostasis of the body by increasing the hydrolysis processes and nutrient absorption of food, as evidenced by increased activity of digestive enzymes of the small and large intestines. The influence Humilid on morphometric parameters ostriches digestive tract, especially the blind gut and quantitative composition data cellulolytic microorganisms in the gut. Scientific novelty of Ukraine confirmed the presence of Patent for utility model number 100524 Method of increasing the activity of digestive enzymes in ostriches using biological additives during the growth to 60 days old. Is offered: to add to the basic diet of black African ostriches biologically active feed additive humic nature "Нumilid" during the period of growth of output up to 60-day-old (at the rate of 1 mg of humic substances per 1 kg of body weight of animals), which optimizes the physiological processes of the body characterized by increased activity of digestive processes, the intensity of the growth of animals, the preservation of livestock ostriches and more profit in the amount of 183 UAH per 1 animal for 60 days. Introduced: The studies formed the basis of methodical recommendations "Using the biologically active food additive "Humilid" for improving the physiological state and increasing productivity of meat of ostriches with their growing industrial age for slaughter in Ukraine steppe climates". Key provisions of the dissertation are used in the learning process of the course "Physiology of Animals", "Physiology of farm animals", "Biochemistry of Animals" and introduced in the scientific research department of Dnepropetrovsk State Agrarian and Economic University, Sumy National Agrarian University, Bila Tserkva National Agrarian University , National University of Life and Environmental Sciences of Ukraine, Kharkiv Veterinary Academy, Podolsky state agricultural and technical University. The research results are introduced into production in corporation "Agro-Soyuz" Synel'nykivs'kyy district Dnipropetrovsk region.
