Influence of oregano and marsh cinquefoil extracts on the physiological status and productivity of young pigs

In modern pig farming, industrial technologies are mainly used. Such technologies allow for more production, but their use is associated with such serious problems as the effects of chronic stress on animals and antibiotic resistance of pathogenic microorganisms associated with the widespread use of antibiotic drugs. Piglets are especially vulnerable to stress during weaning. One way to solve these problems could be the use of plant feed additives based on medicinal plants, such as oregano and marsh cinquefoil. The purpose of the research is to study the effect of extracts of oregano (OE) and cinquefoil (CE) on the physiological status and productivity of young pigs. To conduct the study, three groups of piglets aged 21 days were formed: control, experimental with OE extract and experimental with SE extract (10 ml/kg LW). For three weeks, piglets in the experimental groups received experimental extracts in addition to the main diet. The assessment was carried out according to such indicators as changes in live weight, stress resistance, feed activity, red blood cells (RBC) content, hematocrit, average RBC volume, hemoglobin content, platelet content, average platelet volume, white blood cells (WBC) content, calcium, phosphorus, cholesterol, urea, total plasma protein, blood sugar and triglyceride levels and the concentration of the hormone cortisol. The results showed that the average weight of one pig in the group with CE in the diet was 3.96 % higher than in the control, and the daily gain was significantly (P function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
