The effect of maternal dietary omega (ω)-3 fatty acids on hatchability and growth of broiler chickens
Bibliographic record
Abstract
The effects of different maternal dietary ω-3 fatty acids on hatchability and post-hatch development of the broiler chickens were investigated. Incubated eggs were Low (Lω3), Medium (Mω3) or High (Hω3) in ω-3 fatty acids. The eggs were produced by feeding broiler breeder hens with a wheat-soybean meal diet containing (g/kg) 50 g of sunflower oil (Lω3); 25 g sunflower oil + 25 g fish oil (Mω3); or 50 g fish oil (Hω3). Hens fed the Mω3 diet had highest (P<0.05) fertility and hatchability values 78.26 and 65.35% compared to 69.01 and 47.18% for the Hω3 fed group. However, hens fed the Lω3 diets produced eggs that were significantly (P<0.01) larger than eggs from the Mω3 and Hω3 fed group. Consequently, the day-old chick live-weight were significantly different (P<0.01) with chicks hatched from the Lω3 > Mω3 > Hω3 fed groups. Best performance was obtained from the Mω3 fed group, which might indicate an optimum level of ω-3 for hatchability and growth.

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.
