EFSA Journal, 2023 This Scientific Opinion addresses a European Commission request on the welfare of calves as part of the Farm to Fork strategy. EFSA was asked to provide a description of common husbandry systems and related welfare consequences, as well as measures to prevent or mitigate the hazards leading to them. In addition, recommendations on three specific issues

Journal of Veterinary Internal Medicine, 1988 Abstarct Hypernatremia (sodium chloride intoxication) is described in two calves due to presumed mixing errors of oral electrolyte solutions while undergoing therapy for neonatal diarrhea. The experimental induction of hypernatremia in two clinically normal calves is also reported.

Calves are socially motivated [PDF]
JDS Communications, 2022 Most dairy calves are housed individually in the first weeks and sometimes months of their lives. Lack of social interaction can negatively impact feed intake, social skills, coping abilities, and cognitive performance, but the motivation of calves to seek companionship has seldom been investigated.

The effects of maternal calving date and calving interval on growth performance of beef calves
South African Journal of Animal Science, 2000 This study was undertaken to investigate the growth performance of calves born to dams with different calving dates and calving intervals. Early calving dams produced calves with the lowest birth weights, the highest actual weaning weights and the highest pre-breeding heifer weights.

Earlier calves are heavier calves
California Agriculture, 1969 CATTLEMEN HAVE OBSERVED that calves dropped early in the calving season arc heavier at weaning and more profitable than calves dropped late in the calving season. Animal scientists have pointed out that weaning weight is the result of age at weaning and average daily gain from birth to weaning.

Poikilocytosis of Newborn Calves
The Japanese Journal of Veterinary Science, 1982 出生直後から異常な呼吸速迫を示した牛新生子の多数例において, 著明な赤血球の変形が認められた. これらの呼吸速迫例は500～1,000mlの輸血により速やかに好転, 回復した. 本症は, 体温変化のないこと, 肺聴診で異常がないこと, さらに赤血球の形態異常などから, 肺炎との識別が可能であった.

Pathophysiology of Diarrhea in Calves
Veterinary Clinics of North America: Food Animal Practice, 2009 Infectious diarrhea in calves is most commonly associated with enterotoxigenic Escherichia coli, Cryptosporidium parvum, rotavirus, coronavirus, or some combination of these pathogens. Each of these agents leads to diarrhea through either secretion or malabsorption/maldigestion, though the specific mechanisms and pathways may differ.

The immune response to viruses in calves: II. The response in young calves [PDF]
Journal of Hygiene, 1968 SUMMARYInjections of virus in calves up to about 5 weeks of age caused either the production of both IgM and IgG, or the production of only IgG, or no detectable antibody. In all but one case priming for a secondary response occurred even in the absence of a detectable primary response.
