Effect of milk feeding level on development of feeding behavior in dairy calves
Bibliographic record
Abstract
Evidence exists that early life experiences may influence development of characteristic feeding patterns in dairy cattle. The objective of this study was to determine the effect of milk feeding level on performance and development of feeding patterns in dairy calves. Twenty Holstein bull calves were assigned at birth to a milk replacer feeding level, fed via a teat: (1) ad libitum (ADL) or (2) restricted feeding at 5 L/d (0.75 kg of milk replacer) in 2 feedings/d (RES). All calves were offered concentrate ad libitum during the milk feeding stage. Calves were weaned gradually during wk 7 and then fed a pelleted diet ad libitum for 7 wk. Calves were weighed 2 times/wk. Feed and milk intakes were recorded daily. Feeding behavior was recorded from video for 5 d in each of wk 3, 6, 8, 11, and 14. Calves fed ADL consumed 2.6 times more milk, had greater weight gain (1.2 vs. 0.6 kg/d), and consumed less solid feed (45.2 vs. 98.0 g/d) during the milk feeding period than did calves fed RES. As expected, providing milk ADL resulted in more frequent meals (in wk 6, 7.1 vs. 2.0) and more evenly distributed diurnal patterns of feeding activity compared with the RES milk level. When considering all sucking bouts (milk feeding and nonnutritive sucking), no difference was observed between treatments in daily bout frequency or sucking time/bout. Postweaning, calves fed RES had initially greater rate of intake (24.9 vs. 17.8 g/min) and meal size (160.8 vs. 117.2 g/meal). Diurnal feeding patterns also differed in the first week after weaning, with ADL calves feeding less continuously at the time of feed delivery. Meal characteristics and diurnal patterns of feeding activity were similar between calves by the end of the trial. However, milk feeding level had a longer-term effect on variability in feeding behavior, with calves fed RES having greater day-to-day variability in feeding time and meal size. Variability of meal characteristics also decreased over time across treatments. These results suggest that milk feeding level may have a short-term influence on postweaning feeding behavior. However, differences in early feeding patterns due to milk feeding level do not appear to affect longer-term development of feeding patterns.

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.
