Invited review: The welfare of young calves transported by road
Open accessAbstract
The transport of young calves is a welfare concern. Young calves aged ≤3 mo are particularly vulnerable to compromised welfare, and are at a relatively high risk of morbidity and mortality compared with adult cattle. Calves face several potential challenges to welfare during and after transport, including food and water deprivation, disease, injury, and stress from handling, social mixing, and new environments. The key risk factors identified for poor calf welfare associated with transport include long transport and fasting durations, young age at transport, poor colostral immunity, timing within the calving season, lack of bedding in trucks, and high stocking density. Maximizing calf welfare thus requires a multifaceted approach, such as minimizing transport and fasting durations, transporting at an appropriate stocking density with comfortable bedding, only transporting calves that are healthy and fit, and optimizing pre-transport calf management. More research is needed to understand the effect of transport on the mental or affective state of calves.

The risks of severe hunger and thirst, metabolic exhaustion, and dehydration increase with time without feed and water.
“However, the risks of severe hunger and thirst, metabolic exhaustion, and dehydration increase with time without feed and water (Roadknight et al., 2021).”

The Fasting section reports that glucose declines as time off feed increases, that longer fasting can lead to hypoglycemia, and that calves fasted for 24–30 hours are likely hungry. The Dehydration section reports an association between time off feed and a hydration measure, but characterizes dehydration during fasting and transport as generally mild to moderate and says calves may be thirsty. These passages do not establish increasing risks of *severe* hunger or thirst, or of metabolic exhaustion. (LLM, conf=0.85)
Experimental — accuracy not yet measuredCalves that do not receive adequate nutritional support to mitigate the effects of fasting and low body fat reserves are likely to have an increased risk of morbidity.
“Calves that are not healthy before and during transport have reduced resilience, and those that do not receive adequate nutritional support to mitigate the effects of fasting and low body fat reserves are likely to have an increased risk of morbidity (Roadknight et al., 2021).”

The Disease section (page unavailable) reports that longer fasting and transport were linked to higher posttransport morbidity in preweaned veal calves. The Fasting section (page unavailable) notes calves’ low body fat reserves and says nutritional deficiencies may harm health and immune function. The review does not establish that inadequate nutritional support specifically increases morbidity by failing to offset fasting and low fat reserves; it identifies the effect of longer-term nutrition during transport as a research gap. (LLM, conf=0.84)
Experimental — accuracy not yet measuredDehydration, weight loss, energy depletion, and exhaustion are commonly reported outcomes of long-distance transport and are accompanied by negative affective states such as hunger and thirst.
“Dehydration, weight loss, energy depletion, and exhaustion are commonly reported outcomes of long-distance transport (reviewed by [5, 8]) and are accompanied by negative affective states such as hunger and thirst [9, 10].”
From Effects of age and feeding protocols on the metabolic and physiological condition of unweaned calves during and after long-distance transport (2026) · cites this paper as [5]
The Dehydration section says mild-to-moderate dehydration and weight loss may be reasonably common during fasting and transport, and calves may be thirsty. The Fasting and Duration and Distance of Transport sections describe negative energy balance, possible hunger, and increased muscle fatigue with longer journeys. They do not establish exhaustion as a commonly reported outcome, and they qualify hunger and thirst as possible rather than confirmed states; the review also notes that weight loss may be due primarily to fasting. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
