Effects of lysozyme on the growth performance, nutrient digestibility, intestinal barrier and microbiota of weaned pigs fed diets containing spray-dried whole egg or albumen powder
Bibliographic record
Abstract
Two experiments were conducted to evaluate energy value of spray-dried whole egg (SWE), albumen powder (AP), and effects of lysozyme (LZ) in diets containing these two protein sources. Experiment 1: 18 barrows were allotted to one of the three diets (Basal, SWE, and AP). Both digestible (DE) and metabolizable energies (ME) were lower (P < 0.01) in AP than SWE. Experiment 2: 120 piglets weaned at 21 d were allotted in a 2 × 2 factorial experiment. Diets contained either 8.0% SWE or 4.67% AP, supplying the same amount of crude protein and were fed with or without 1 g kg−1 LZ. Supplementation of LZ in SWE and AP diets improved (P < 0.01) G:F than the diets without LZ. Lysozyme decreased (P < 0.01) Escherichia coli counts in cecum and Lactobacilli counts in both cecum and colon (P < 0.05). Lysozyme reduced serum IgM (P < 0.05), d-lactic acid (P < 0.01), and diamine oxide (P < 0.05). Piglets fed AP had lower (P < 0.05) serum urea nitrogen levels than those fed SWE. In conclusion, SWE contains higher DE and ME contents than AP. Lysozyme improved the performance of piglets by regulating the gut microflora, protecting the intestinal barrier and lowering immune activation.

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.
