Abstract

Introduction. Genetically modified soy is characterized by a high protein content (38-42%), which contains all the essential aminoacids, many polyunsaturated fatty acids, vitamins, macro and micronutrients, so it comprise of many foods: bread, biscuits, margarine, pizza, sausage, candy, milk, yogurt, baby food and others, but the final opinion on their safety there. This problem is disturbed both as scientists around the world as ordinary people.

The aim of this study was to examine changes in the reproductive capacity of three generations of pigs, which are constantly fed GM raundapstable soy.

Material and methods. Two groups of piglets - and generation (control and research, 2 females and 2 males). After two months after farrowing sows have been separated from . In the control group diet was added 15-20% for crude protein sunflower meal and pea middlings and in research -15-20% for crude protein thermally treated ground raudapstable GM soy. Reproductive ability of females assessed by live weight the natural pairing and the number of stillborn piglets alive and after farrowing; and hogs - on live weight, development of testis and sexual activity. The same experimental conditions were performed in the second and third - generation mature boars examined histologically and biochemically defined fatty acid composition.

Results. Long-term feeding by raundapstable soybean piglets from two-month age to puberty I, II and II generations adversely affect the reproductive ability, shown inhibition of sexual desire, increase live weight gain during his appearance, the development of significant violations of blood supply, necrotic and degenerative, inflammatory and dysplastic tumor-like processes in the testicles, especially the third generation of males.

Conclusions:

The long-term feeding pigs by raundapstable GM soybean in male pigs inhibited sexual desire, especially in the third generation.

Histologically the testes in males subjects found significant third generation circulatory disorders, necrotic, degenerative, inflammatory and tumor - dysplastic processes.

Biochemically was found that the fatty acid composition of the testicles hogs that received a diet of GM raundapstable soy not significantly different from controls.
