The influence of feeding GMO-peas on growth of animal models
Keywords:geneticaly modified crops, pea preclinical studies
Introduction of genetically modified (GM) food or feed into the commercial sale represents a very complicated process. One of the most important steps in approval process is the evaluation of all risks on the health status of people and animal models. Within our project the genetically modified peas was breeded that showed significant resistance against Pea seed-borne mosaic virus and Pea enation mosaic virus. Preclinical studies have been conducted to found out the effect of GMO peas on animals - rats of outbreeding line Wistar. In a total, 24 male, specific pathogen free Wistar rats were used in the experiment. At the beginning of the experiment, the animals were 28 days old. The three experimental groups with 8 individuals were created. The first group of rats was fed with GMO peas, the second group of rats consumed mix of pea cultivar Raman and the third group was control without pea addition (wheat and soya were used instead of pea). In the present study we focused our attention on health, growth and utility features of rats fed with GM pea. All characteristic were observed during the experiment lasting 35 days. Consumed feed was weighted daily and the weight of the animals was measured every seven days. The average values were compared within the groups. The aim of the experiment was to verify if resistant lines of pea influence the weight growth of animal models. The results of our experiment showed that even a high concentration (30% of GM pea) did not influence growth rate of rats to compare with both rats fed with pea of Raman cultivar and control group. We did not observe any health problems of animal models during the experiment.
