The effect of varying levels of corticated marama bean (Tylosema esculentum) meal on growth performance, apparent retention of feed components, and physiological and meat quality parameters in Jumbo quail
Bibliographic record
Abstract
This study evaluated the effect of varying levels of corticated marama bean ( Tylosema esculentum ) meal (CMBM) on growth performance, apparent retention (AR) of feed components, and physiological and meat quality responses in Jumbo quail. Five isocaloric and isoproteic diets were formulated to contain 0 (T1), 51.25 (T2), 67.49 (T3), 83.74 (T4), and 99.98 g/kg (T5) of CMBM. A total of 385, one-week-old quail chicks (26.7 ± 2.16 g live-weight) were placed in cages (11 birds/cage) based on body weight. The diets were allocated to cages in a completely randomised design to give 7 replicate cages per diet. Feed intake (FI), body weight gain (BWG), gain-to-feed ratio (G:F), as well as AR of feed components were measured. The birds were slaughtered at day 35 for measurements of blood indices, organs weight, carcass and meat quality attributes. Feeding increasing levels of CMBM reduced FI ( P = 0.005) linearly in week 2 but had no effect on FI in weeks 3–5. Similarly, linear reductions ( P < 0.0001) were observed for average weekly BWG and G:F in weeks 2 and 3. A positive linear effect ( P = 0.033) and a negative cubic effect ( P = 0.048) for AR of neutral detergent fibre and organic matter were recorded as CMBM levels increased, respectively. However, varying responses ( P < 0.05) were observed for AR of essential amino acids (methionine, lysine, threonine, etc.). Serum lipase, neutrophils, eosinophils, monocytes, and basophils linearly increased ( P < 0.05) with dietary CMBM levels. Significant cubic or quartic effects ( P < 0.05) were recorded for serum glucose, albumin, white blood cells, neutrophils, monocytes, basophils, and platelets. There were negative linear effects ( P < 0.05) for final body weight, carcass yield, and breast meat drip loss. However, linear increases were recorded for gizzard, proventriculus, small intestine, and large intestine weights as dietary CMBM levels increased. In conclusion, the inclusion of CMBM up to 99.98 g/kg in Jumbo quail diets compromised growth performance, physiological responses, slaughter weights and carcass yield of Jumbo quail.

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.
