    Opis:
    The aim of this study was to determine the effect of fish meal and mineral-vitamin premix, supplementing organic diets, on the performance of pigs and some meat and blood characteristics. The experiment was conducted on an organic pig fattening farm. The study involved 120 pigs with an approximate 25 kg body weight. Animals were divided into 3 groups, kept in pens, 10 animals each. Group I (control) animals were fed with plant feedstuffs of organic origin. Diets for group II and III were enriched with fish meal or fish meal and vitamin-mineral premix, respectively. The experiment was carried out till pigs reached a weight of 115 kg. Feed samples were subjected to laboratory analyses. Body weight (3 times) and feed intake were recorded. Blood samples were collected (2 times) to determine hematological and biochemical indices. Some parameters in meat samples were also determined. The fish meal addition improved (P ≤ 0.05) the average daily gains as well as feed conversion ratio during fattening period and mineral-vitamin premix significantly (P ≤ 0.05) fortified fish meal influence. Fish meal supplement improved (P ≤ 0.05) also some carcass characteristics. Supplementation of the diet with premix additionally decreased (P ≤ 0.05) backfat thickness and increased share of meat in carcass. Fish meal improved (P ≤ 0.05) some meat characteristics and elevated content of some polyunsaturated fatty acids. An increase in hemoglobin, red blood cell, white blood cell and cholesterol level in blood of animals from both experimental groups were also found. The results obtained proved the usefulness of fish meal and mineral-vitamin premix in the fatteners nutrition based on organic diets.

    Opis:
    An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C - standard feeding), and experimental, supplemented with preparations: E-1 herbal-humic, E-2 humic-herbal and E-3 - humic-lucerne. Hens were placed in the pens on the 16th week of life, addition of preparations with standard food mixture started at the 22nd wk and lasted until 66th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminot-ransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne preparation affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l), Glu 10-15 mmol/l), TCh (2.2-4.5 mmol/l), TAG (10-24 mmol/l), AST (4-12 U/l), ALT (150-280 mmol/l) and ALP (190-350 U/l).
