Abstract
Simitzis, P. E., Symeon, G. K., Charismiadou, M. A., Ayoutanti, A. G. and Deligeorgis, S. G. 2011. The effects of dietary hesperidin supplementation on broiler performance and chicken meat characteristics. Can. J. Anim. Sci. 91: 275–282. An experiment was conducted to examine the effects of supplementing broiler feed with hesperidin, a bioflavonoid that is an abundant and inexpensive by-product of citrus cultivation, on growth performance, carcass characteristics, breast meat quality characteristics and the oxidative stability of breast meat. Eighty 308-d-old Ross male broiler chickens were randomly assigned to four groups. One of the groups served as a control (C) and was given commercial basal diets, whereas the other three groups were given the same diets further supplemented with hesperidin at 1.5 g kg−1(HE1), or hesperidin at 3.0 g kg−1(HE2), or α-tocopheryl acetate at 0.2 g kg−1(VE). At 40 d of age, broilers were fasted for 12 h, weighed and slaughtered. After overnight chilling, carcasses were trimmed for breast fillets by removing skin, bones and connective tissue. The right pectoralis major muscle was used for quality parameters estimation, whereas the left pectoralis major muscle for lipid oxidation measurements. No significant differences were observed after dietary hesperidin or α-tocopheryl acetate supplementation in final body weight (kg), body weight gain (g), feed conversion rate and internal organs weight (g). Shear values (N mm−2), intramuscular fat (%) and cooking loss (%) were also not significantly influenced by the dietary treatments. Significant differences were found concerning pH24and color parameter values among the treatment groups. Measurement of lipid oxidation values showed that as hesperidin increased in the diet, malondialdehyde values decreased in tissue samples, suggesting that hesperidin particularly at 3 g kg−1exerted an antioxidant effect on chicken tissues (P<0.01). However, dietary α-tocopheryl acetate supplementation at 0.2 g kg−1of feed displayed greater antioxidant activity than hesperidin at either supplementation rate (P<0.01). In conclusion, hesperidin, an abundant component of citrus pulp, positively influences meat antioxidative properties without negative implications on growth performance and meat quality characteristics in poultry, thus appearing to be an important additive for both the consumer and the industry.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
