The objective of the study is to establish the effect of the fat level in the diet on the meat productivity of rabbits with a dry type of feeding. Objectives: to develop 2 recipes for CGF for young rabbits taking into account the recommended norms of nutrients and energy, differing in the fat-to-carbohydrate ratio; to organize the production of CGF in factory conditions; to form experimental groups of rabbits for conducting a scientific and economic experiment based on the analog principle; to conduct a scientific and economic experiment on young Soviet Chinchilla rabbits during the fattening period; to conduct laboratory studies confirming the initial hypothesis. The scientific and economic experiment was conducted on young Soviet Chinchilla rabbits. From 50–42-day-old rabbits, 2 groups-analogues by origin, age and live weight were formed, 25 heads in each, the 1st group is a control group, the 2nd group is an experimental group. Rabbits are kept in a shed, the type of feeding is dry. The rabbits of each group received their own complete granulated feed (CGF), manufactured at the factory. The feeds of the control and experimental groups differed in the level of fat and soluble carbohydrates. In the experimental group of rabbits, there was 2.1 times more fat than in the control diet due to the addition of sunflower oil. As a result, the experimental group increased the growth rate of rabbits, slaughter weight by 9.0 %, carcass weight by 6.5 % with more rational use of feed, the feed conversion ratio (FCR) in the experimental group was lower by 0.51. It is advisable to study the effect of even higher fat levels in fattening rabbit diets on meat productivity and the quality of their meat.
