Effects of ketoprofen alone or in combination with local anesthesia during the castration of bull calves on plasma cortisol, immunological, and inflammatory responses.
Surgical castration induced a significant elevation in cortisol secretion; the rise in cortisol was reduced to control levels by the administration of ketoprofen but not local anaesthetic, suggesting systemic analgesia using ketop rofen is more effective than local anesthesia during castration to alleviate the associated stress response.
Calf health from birth to weaning. I. General aspects of disease prevention
This review considers both pre- and periparturient management factors influencing calf health, colostrum management in beef and dairy calves and further nutrition and weaning in dairy calves.
Transportation of young beef bulls alters circulating physiological parameters that may be effective biomarkers of stress.

A pattern of phenotypes in the circulation of transportation-stressed bulls may aid in the future detection of disease-susceptible cattle after transportation, and there was also an effect of breed for all variables except plasma urea, creatine kinase, and testosterone, perhaps indicating that a genetic component contributed to the physiological response to transportation stress.
The effect of abrupt weaning of suckler calves on the plasma concentrations of cortisol, catecholamines, leukocytes, acute-phase proteins and in vitro interferon-gamma production.
Abrupt weaning increased plasma cortisol and noradrenaline concentrations that were accompanied by attenuation of in vitro interferon-gamma production to novel mitogen and antigen complexes up to 7 d after weaning.

The results show that efficient RFI heifers consumed less feed without any compromise in growth, body composition, or maternal traits measured.
Effect of 12-hour road transportation on physiological, immunological and haematological parameters in bulls housed at different space allowances.
Effect of ketoprofen, lidocaine local anesthesia, and combined xylazine and lidocaine caudal epidural anesthesia during castration of beef cattle on stress responses, immunity, growth, and behavior.
B burdizzo castration increased plasma cortisol and acute-phase proteins, and suppressed immune function and growth rates, and systemic analgesia with ketoprofen, a non-steroidal antiinflammatory drug, was more effective in reducing inflammatory responses associated with castration than LA or EPI.
Gene expression signatures in neutrophils exposed to glucocorticoids: a new paradigm to help explain "neutrophil dysfunction" in parturient dairy cows.

Pneumonia in recently weaned suckler calves is considered, where the key risk factors are related to the time of weaning and the efficacy and economical viability of vaccination against respiratory disease in calves remains unclear.
