Biosorption process was used for obtaining of mineral mixtures for sheep enriched with zinc, manganese, cooper and iron ions. VFA (volatile fatty acids) profil in rumen chyme consists of etan acid, propan acid, and butan acid in proportion 11:2.2:1, what indicated normal physiological process. There were slight changes in reciprocal influence of these acids after addition of substrates in 4th and 8th hour of fermentation. The results analysis proved slight decrease of ethanoic acid level in 24th hour of fermentation in groups with mixture enriched with supplements after biosorption process. Furthermore others indicators of fermentation, measured based on VFA level revealed small decrease of ethanoic acid concentration. Production of isobutanoic acid and isopentanoic acid in experimental groups as well as in control group at 8th hour of fermentation decreased. Increase of methane production and NGR index were observed in samples enriched with mineral compounds. Conducted experiments showed, that mineral supplements for sheep enriched in biosorption process have no negative influence on rumen fermentation products. The maintenance production of VFA in 4th and 8th hours of fermentation revealed advantageous influence of using substrates in activity of symbiotic microorganisms participating in rumen fermentation.

In commercial fish farming units you can look at various biochemical and morphological markers for a greater understanding of health and disease status of the unit. Aim of a study was to examine some biochemical metabolic indicators in some common diseases in farm carp. Especially levels of ammonia in branchionecrosis (BN). The research was done in 2009–2011 and 120 carp of 25–90 g less than one year old were sampled for the following diseases: spring viraemia of carp SVC and CE, swim bladder infection, branchionecrosis and also any appearance of transsudative changes in fish with no clinical signs. The research was done in the Lower Silesia region. These indicators can be useful in determining the health of the fish and possible causes of an illness. Electrolytes, protein assays and hematology are useful in diagnosis in carp disease thus enabling more effective treatment. Low sodium levels in particular are a useful predictor of a disease.

The year 2014 marks the round anniversary of 100 years of the pioneering constitution type research on the native Polish horse breed – Polish Konik, which was initiated by two eminent hippologists – Jan Grabowski and Stanisław Schuch. Genetically and environmentally, the breed is extremely valuable not only because of the their primitive traits, which these horses inherited from their direct ancestors – the tarpan horses, but mainly due to the fact that in a natural world, the Polish Konik horses, next to the Przewalski horse, represent, for the representatives of the Equus caballus, an invaluable genetic reserve of the primitive biological features, especially those related to longevity and health. The purpose of this study was the characterization of the Polish Konik horses, giving a broad outline of their diverse usability to the wider group of readers outside Poland and bringing attention to the accuracy and reasonable necessity to protect this breed that is priceless to the natural world.
