Potential benefit of a thoracic squeeze technique in two newborn calves delivered by caesarean section.

Two calves delivered following elective caesarean section showed behaviour typical of neonatal maladjustment syndrome described in foals, i.e., indifference to environmental stimuli, lack of affinity for the dam, failure to find the udder, refusal to suck, aimless wandering or motionless standing. Calves were subjected to a clinical examination immediate after delivery and there were no signs of defects, illness, pain, dehydration, hypoxia, acidaemia or other causes for the unresponsive behaviour. Both calves were subjected to the thoracic squeeze technique, one at 6 hours and the other at 20 hours after delivery. A soft rope was looped around the thorax and gentle pressure was applied to the free end of the rope, squeezing the calf's chest for 20 minutes. Both calves exhibited a sleep-like state manifested by closed eyes, no body movements, slow breathing and a decrease in heart rate, for the entire squeezing period. When the rope was removed the calves woke up immediately, rose and walked towards the dam. When led to the dam's udder, the weaker calf began to suck. Both were reported, by the stockperson, to follow the dam and suck normally the following day. Provided all other disease processes are excluded, very young calves that exhibit indifference to environmental stimuli and lack of affinity for the dam may be good candidates for application of the thoracic squeeze technique that has been demonstrated to have clinical efficacy in foals with neonatal maladjustment syndrome.
