Nutritional supplementation of ahiflower seed and press cake in laying hens and its effect on production performance, nutrient digestibility, egg quality, and yolk omega-3 fatty acid enrichment during mid- to post-peak production phase
Bibliographic record
Abstract
Ahiflower seed (AFS) and ahiflower press cake (AFP) are rich in n-3 fatty acids and other nutrients that can be beneficial for laying hens or deposited in their eggs. A total of 288 36-week-old white leghorn hens were allocated into eight treatments with six replicates of 6 birds/cage for 12 weeks. The treatments included the control (CON), CON + 10% flaxseed (10%FX), 1, 5, or 10% AFS, or 5, 10, or 15% AFP. Overall, 10%AFP increased BW compared to 1%AFS. Diets did not affect n-6/n-3, apparent total tract digestibility (ATTD) of energy, and most of the egg quality parameters. In the egg yolk, stearidonic acid was increased (P<.0001) in 10%AFS (0.15mg/g) compared to CON (0.01mg/g), 10%FX (0.08mg/g), and all other treatment groups. The eicosapentaenoic acid was increased (P=0.0001) in 10%AFS (0.28mg/g) and 10%FX (0.29 mg/g) compared to CON (0.05mg/g). Compared to CON (1.49 mg/g) and other treatment groups, 10%FX (9.47mg/g) increased (P0.000) α-linolenic acid while docosahexaenoic acid was increased (P0.000) by 10%AFS (5.39mg/g) compared to CON (2.82mg/g). Hens fed 10%FX, 5% and 15%AFP had increased (P=0.0001) linoleic acid (34mg/g) compared to CON (26.6mg/g). In conclusion, 10%AFS increased n-3 FAs in egg yolk with no effect on egg quality, eggshell Ca and P levels, ATTD of energy, and n-6/n-3 ratio.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
