The demand among the population for protein products, which are essential for a healthy diet, is a pressing issue today, which constantly requires scientists and manufacturers to search for alternative protein analogues. That is why the aim of the research was to study the impact of a diet based on plant and animal raw materials on the reproductive capacity, growth, and development of the body. In the experiment, the duration of pregnancy in pregnant females was determined; the average number of rats born per female of the respective group; the weight of females before pregnancy; the weight of females on the 7th, 14th and 21st day of pregnancy. The postnatal development of rats of the control and experimental groups was compared. In newborn rats, the following were determined: age of ear drum detachment; craniocaudal size at birth; craniocaudal size on the 5th day; age of hair coat appearance; age of eye-opening; weight of rats at birth; weight of rats on the 7th, 14th and 30th day of life. The results obtained indicate that there is no negative effect of the vegetable semifinished product using soya-wheat texture and meat cutlet on the reproductive functions of rats and the development of offspring. During the experiment, female rats showed no signs of toxicosis, visible pregnancy disorders, or physiological disorders. During the dynamic observation of the weight of experimental females in all experimental groups, no decrease in weight gain was recorded compared to control animals. The weight and postnatal dimensions of newborn rats of the experimental groups did not differ from those of the control. For the first time in laboratory animals, based on an integrated approach using modern research methods, the effect of long-term consumption of food based on semifinished products from soy-wheat texture and meat cutlets on the reproductive functions of rats and the development of offspring was studied, which is of practical value in the context of the health of females and offspring of mammals under the influence of an alternative nutritional factor
