Abstract. The aim of this study was to determine the effect of vitamin E and polyphenols on the antioxidant potential and meat quality of broiler chickens fed diets supplemented with low-quality oil. The experimental materials comprised 120 male Ross 308 broilers (six treatments, 10 replications, two birds per replication). Dietary supplementation with vitamin E and/or polyphenols was applied in the following experimental design: group I (negative control) – without supplementation without low-quality oil; group II (positive control) – without supplementation + low-quality oil; group III – supplementation with 100 mg kg−1 of vitamin E+ low-quality oil; group IV – 200 mg kg−1 of vitamin E + low-quality oil; group V – 100 mg kg−1 of vitamin E and 100 mg kg−1 of polyphenols + low-quality oil; group VI – 200 mg kg−1 of polyphenols + low-quality oil. Rapeseed oil oxidised under laboratory conditions was added to the diets of broiler chickens from groups II to VI. The applied antioxidants had no effect on the growth performance of chickens fed oxidised oil. Increased dietary inclusion levels of vitamin E and/or polyphenols improved the antioxidant status in the blood and increased the content of non-enzymatic antioxidants in the liver and breast muscles of broilers fed low-quality oil. The tested antioxidants had no influence on carcass quality parameters in chickens fed oxidised oil. However, birds fed diets with the addition of vitamin E were characterised by a higher gizzard weight and higher pH of gizzard digesta. Dietary supplementation with vitamin E and polyphenols or polyphenols alone contributed to a lighter colour and lower pH of breast muscles and an increase in the content of fat and ash in the breast muscles of broilers fed oxidised oil. The breast muscles of birds given 100 or 200 mg kg−1 of supplemental vitamin E were characterised by higher concentrations of n-6 polyunsaturated fatty acids (PUFAs) and hypocholesterolemic fatty acids (DFAs), a more desirable DFA∕OFA ratio, and a lower atherogenicity index (AI). Polyphenols combined with vitamin E can be a valuable component of diets for broiler chickens when the problem of low-quality oil occurs.

The effects of an oregano and/or rosemary (Origanum vulgare L. and/or Rosmarinus officinalis L.) dietary supplementation to the diet of fattening pigs were investigated. Thirty-two grower-finisher pigs (45 kg) were divided into four dietary groups identified as: control diet (CTR); CTR+ 0.2% oregano (O); CTR + 0.2% rosemary(R), and CTR+ 0.1% oregano + 0.1% rosemary (OR). During the finishing period, all groups received a further supplementation of 0.5% of conjugated linoleic acids (CLA). Blood samples were collected after an adaptation period of 15 days to the new diet (T1) and at the end of the finishing period (T2) to evaluate antioxidant status (total antioxidant power and reactive oxygen metabolites) and immune responses (lymphocytic phenotyping and IgG levels). Pork meat samples were evaluated for glutathione peroxidase activity (GSHPx), total phenolic content and preference rating. A significant increase in B lymphocytes (CD79+) and a higher IgG level was observed in the R and O groups (P<0.05). Furthermore, there were significant effects of dietary supplementation on meat GSHPx activity and total phenolic contents (P<0.001 and P<0.005, respectively). Preference rating showed that pork derived from group R was the most preferred by the consumers.

In this trial we aimed to assess the effects of dietary supplementation of 4-O-methyl-glucuronoarabinoxylan (4OMG) on growth performance, thigh meat quality and small intestine development of female Partridge-Shank broilers. A total of 240 1-day-old female Partridge-Shank broilers were randomly distributed to four groups with three replicates of 20 within each group. Groups received either 0, 15, 20 or 25 g 4OMG/kg DM of diet. During the whole experiment of 60 days, broilers had ad libitum access to water and feed. At pen level, feed intake was recorded daily and broilers were weighed at the start and end of the experiment. For each group, three pens with a total of 20 broilers were randomly selected to determine the thigh meat quality and the small intestine development of broilers. Broilers fed diets with higher 4OMG had greater final liveweight (P = 0.004), daily bodyweight gain (P = 0.004) and gain-to-feed ratio (P < 0.001), muscle pH values (P = 0.031) and redness (P = 0.001), duodenal weight index (P = 0.042), jejunal (P = 0.043) and ileal length (P = 0.049), duodenal (P < 0.001) and ileal villus height (P = 0.008), but lower percentage of dead birds (P < 0.001), drip loss (P = 0.042) and shear force value (P = 0.043) of the thigh muscles. These results indicate that increasing dietary supplementation of 4OMG may improve growth performance and meat quality of female Partridge-Shank broilers through better development of small intestine.
