1430 Effect of partially replacing barley grain with liquid whey permeate in diets for finishing lambs on dry matter intake, average daily gain, and total tract digestibility
Bibliographic record
Abstract
The objective of this study was to evaluate the effect of partially replacing barley grain with liquid whey permeate in diets for finishing lambs on DMI, ADG, and apparent total tract digestibility. Eighteen wether lambs were individually housed and randomly allocated to 1 of 3 dietary treatments in a completely randomized design. The control diet (CON) consisted of 67.7% barley grain, 20% barley silage, and 12.3% mineral and vitamin supplement on a DM basis. For the moderate-sugar (MOD) and high-sugar (HIGH) treatments, whey permeate was included in the diet at 5 and 10% on a DM basis, respectively, by replacing an equal proportion of barley grain. Water was added to equalize dietary DM content among diets with a targeted DM content of 53.5%. Lambs were provided with a 12-d dietary transition protocol (2 dietary steps) to gradually adapt them to the finishing diet. Subsequently, a 28-d treatment period was imposed with the final 4 d used for measurement of DMI and total fecal collection. Data were analyzed using the mixed model of SAS with the fixed effect of treatment. Addition of whey permeate did not affect DMI (P = 0.96) or ADG (P = 0.43) with average values of 1.22 ± 0.148 and 0.19 ± 0.026 kg/d, respectively. Total tract digestibility of sugar in the MOD treatment was greater (95.1 vs. 69.5 ± 6.32%; P = 0.04) than for CON whereas the HIGH treatment did not differ from CON or the MOD treatment. The apparent digestibility coefficients for DM (74.7 ± 2.74%), OM (76.8 ± 2.55%), starch (98.7 ± 1.32%), CP (65.5 ± 3.47%), NDF (36.43 ± 7.07%), and ether extract (74.34 ± 3.57%) did not differ among treatments (P > 0.10). The results of this study indicate that liquid whey permeate can partially replace barley grain without negative effects on DMI, ADG, or digestibility. In addition, our results show that a low inclusion rate (5% DM) may improve sugar digestibility.

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.
