Plants are a rich source of medicines for various diseases. Each plant produces primary and secondary metabolites, including compounds such as essential oils, phenolic compounds, terpenoids, alkaloids, steroidal compounds, glycosides, terpenes and tannins, which may be responsible for various therapeutic effects. Different parts of Juglans regia, the walnut, contain potent chemical components. The antimicrobial effect of walnut is mainly due to its phenolic compounds.
The aim is to study the effect of a dietary supplement based on a decoction of walnut membranes on the productivity, frequency of diarrhoea and haematological parameters of piglets before and after weaning.
For the study, two groups of suckling piglets aged 21 days were formed, 50 heads in each group. Piglets for the experiment were selected in accordance with the principle of analogue pairs by breed, weight and age. The first group served as a control. The second group received 1 ml of aqueous extract of walnut (Juglans regia) once a day, in the morning, by direct injection into the oral cavity using a disposable syringe.
No cases of diarrhoea were recorded in the experimental group during the first stage of the experiment (before weaning), while in the control group there were 7 such cases, which is 14% of the livestock of this group. In terms of average daily weight gain, the experimental animals significantly (p≤0.05) outperformed the control animals by 14.5 g (5.35 %).
During the second stage of the study (after weaning), 3 cases of diarrhoea were recorded in the experimental group (6% of the livestock), while 20 cases (40%) were recorded in the control group. The difference in the average daily weight gain between the experimental and control groups was significantly higher (p≤0.05) by 12.12%.
The results obtained are obviously associated with the normalisation of digestion due to bactericidal and bacteriostatic effects.
The use of walnut membrane decoction for seven days before weaning significantly (p≤0.05) contributed to an increase in blood glucose content in experimental pigs by 21.7 %. There was also a significant (p≤0.05) increase in the amount of pyruvic acid in the blood of piglets of the experimental group by 13.86 %. A similar effect was observed when using the supplement for piglets after weaning. Such data may indicate a certain activation of metabolism in pigs when using a preparation based on walnut membranes
