Bark charcoal powder containing wood vinegar liquid can shorten the time to shipping of broilers raised in tropical areas by activating performance and intestinal function
Bibliographic record
Abstract
The effect of dietary bark charcoal containing vinegar liquid (BCV) on the growth performance, carcass and visceral organs, intestinal histology, fecal ammonia nitrogen, and nutrient digestibility were investigated in a total of 350 one-day-old unsexed Ross 308 broilers raised under a high environmental temperature (heat stress) from 0 to 42 d of age. They were divided into 0% (control group), 1%, 2%, 3%, and 4% dietary BCV groups. Compared with the control group, the body weight gain (BWG) of the 1% dietary BCV group at 21–42 d of age and the feed efficiency of the 2% dietary BCV group at 0–42 d of age increased (P < 0.05). The carcasses of the 1% and 3% dietary BCV groups significantly decreased (P < 0.05). The digestibility of dry matter and gross energy of the 4% dietary BCV group improved at 21 d (P < 0.05). The duodenum of the 3% and 4% dietary BCV groups was significantly heavier than those in the control groups (P < 0.05). This result suggests that BCV can shorten the time to shipping date for broilers to before 42 d of age and can contribute to the development of poultry production in tropical regions.

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.
