“…The obtained results may be related to the occurrence of different types of hair cover in sheep and goats. In the case of sheep, it is wool, the task of which is to maintain adequate thermal insulation of the skin; additionally, a suint is deposited on the skin, which can constitute from 3 to 30% of the weight of wool [ 5 , 16 ]. Due to the content of fatty acids, the suint has bacteriostatic properties [ 17 ], which could have resulted in a lower and less differentiated level of the studied groups in sheep compared with goats.…”

“…Therefore, for ruminants, both the digestive system and the skin microbiome (related to the production of wool or leather) are important. It should be taken into account that the skin, in case of improper maintenance conditions or diet, will often show any abnormalities or changes occurring in the body [ 5 , 6 , 7 ]. In recent years, apart from environmental factors, genetic factors (including even individual ones) that may affect the animal microbiome are also taken into account—which is also important for the breeder to react faster to abnormalities in the animal’s health.…”

For decades, skin has been assigned the main role of an insulator of the inside of the body from the external environment, but it also plays a role in maintaining homeostasis. In this study, the level of selected bacterial phyla (Firmicutes, Bacteroidetes, Proteobacteria and Actinobacteria) was assessed in three sheep breeds (Świniarka sheep, Uhruska sheep and BCP line (synthetic sheep breed; n = 6) and in two breeds of goats (Boer, Saenian; n = 6) living in the same environment and fed on the same feed, where the aim was to identify differences in terms of race, species and individual differences. Significant differences were found in Firmicute, Actinobacteria and Proteobacteria phyla (p ≤ 0.05). Statistically significant and positive correlations were demonstrated between Actinobacteria and Proteobacteria, Proteobacteria and Bacteroidetes or Firmicutes and Bacteroidetes. The obtained results suggest that the species and racial differences in the level of the studied bacterial phyla may also result from the physicochemical differences of the skin surface, as they could exacerbate the variations in humidity, temperature, composition of antimicrobial peptides (AMP) and lipid content. In addition, individual differences were observed, which indicate a similar effect of an individual on the microbiological composition of its organism.
