The objective of this work was to investigate the influence of dietary peas: linseed mixture (3:1) on the performance and certain serum biochemical parameters of weaned piglets. The faecal bacteriological and fungal composition and diarrhoea incidence was done as well. A total of 20 weaned piglets, 28 ± 3 days of age, were assigned randomly to 2 groups: control diet (C diet) with a classical diet (corn and soybean meal) and peas: linseed diet (PL diet, 3:1). The lipid and protein profile were determined by Analyser BS – 130. The cortisol serum concentration was determined with an Immulite 2000 (Siemens). The serum lipase concentration was determined by the spectropho- tometer method. The number of microorganisms from the faeces samples was determined by counting the colonies obtained on selected media for each particular microorganism. The dietary addition of peas: linseed mixture did not influence the performance (P>0.05). The serum markers: cholesterol, triglycerides, total protein and their fraction did not differ significantly between treatments. Except the protein, which was slightly under the recommended limit, the other markers were within the physiological limits. The dietary fat content was similar. Serum lipase level in weaned piglets decreased insignificantly by dietary incorporation of peas: linseed (<9.06% in PL diet compared to C diet). The lower level of serum lipase in PL diet was reflected in a higher level of triglyceride (>1.10 times) and cholesterol (>1.06 times). The cortisol level was reduced by 94% by peas: linseed addition. The vegetable protein source did not have a significant influence on the bacteria of the faeces. After 2 weeks from weaning, the bacteria count was slowly higher in PL diet compared to C diet, as shown by a higher incidence of diarrhoea. We can conclude that peas and linseed are valuable vegetable sources for weaning piglets, their combination delivering an opportunity to have an optimal diet.
