When humans began interfering with the environment to produce food, some free-ranging animal species adapted to live on typical farmland, sometimes choosing it as their main habitat. They use it on the basis of symbiosis or as a pest. The animals affect farms in different ways, and the same concerns farms affecting animals. There are negative, from a human perspective, as well as positive aspects of this interaction. The aim of this study was to review and propose the solutions to reconcile these two factors, agriculture and wildlife, using Poland as an example. Two major problems were observed: the negative impact of agriculture on the occurrence or abundance of certain species, and wildlife damage caused mainly by wild boars (Sus scrofa) and Cervidae. The most important issue for agricultural economy is the strict control and limitation of the wild boar population, while the farmer's approach to cultivation and the environment are important for the wildlife. For years, man has been undertaking various activities using and subordinating elements of the environment, and each even small interference in the system that creates a harmony will have far-reaching consequences.

Background: The microbiome of the digestive tract of ruminants contains microbial ecosystem that is affected by both environmental and genetic factors. The subject of this study concerns the influence of selected genetic factors, such as species of animals and "host" individual differences on the digestive tract microbiome composition. The results show the core microbiological composition (Firmicutes and Bacteroidetes) of ruminants digestive tract (based on feces) depending on breed and "host". The Bacteroidetes and Firmicutes phyla are the most abundant in ruminants digestive tract. The aim of the study was to determine the differences prevalence level of Bacteroidetes and Firmicutes phyla in feces of Charolaise cattle and Polish Olkuska Sheep with respect to intra- and inter-species variability., Results: The research group in the experiment consisted of animals at the age of 3 months kept in the same environmental conditions - rams of Polish Olkuska Sheep (n = 10) and Charolaise bulls (n = 10). Feces were collected individually from each animal (animals without disease symptoms were selected), living on the same environmental conditions. The analysis of the results in terms of species showed differences in the Firmicutes phylum level and Lactobacillaceae family between rams and bulls. Subsequently, the analysis performed for the "host effect" showed differentiation in the levels of the Bacteroidetes and Firmicutes phyla between individuals in a group and also between the groups., Conclusion: The obtained results suggest that, apart from the diet and the environment, the species and the individual host are equally important factors influencing the microbiological composition of the digestive system of ruminants.
