Data were 876 birth records and 727 weaning records of straightbred and F3 crossbred calves produced in the third generation of a five-breed diallel. Among straightbreds at birth, Holstein calves were heaviest and widest at the shoulders and hips. Jersey calves were lightest and narrowest at the hips, and Brahman calves were narrowest at the shoulders. Holstein crosses tended to be larger at bi...
Chronically critically ill patients often undergo prolonged mechanical ventilation. The role of noninvasive ventilation (NIV) during weaning of these patients remains unclear. The aim of this study was to determine the value of NIV and whether a parameter can predict the need for NIV in chronically critically ill patients during the weaning process. We conducted a prospective study that include...
Two hundred sixty-two sows were used to investigate the effects of boar exposure during the last week of nursing (BPRE) and after weaning (BPOST) on the return to estrus. Because approximately one-half of the sows were weaning their first litter, a third factor, primiparous vs multiparous (LITT), was considered in the statistical analysis. To evaluate the effect of treatment on ovarian activity...
Approximately 20% of all mechanically ventilated patients fail their first attempt to wean. Prolonged mechanical ventilation increases morbidity, mortality, and costs. No single weaning parameter predicts patient ability to wean. Weaning studies suggest that daily trials of spontaneous breathing for appropriate patients assured by standing protocol and driven by respiratory care practitioners a...
Nurse-led weaning can improve patient outcome. Exploration of the factors that influence the commencement of weaning. Themes of decision-making, pathophysiological and multidisciplinary team factors emerged. Experience was a key factor in the decision to wean. The use of protocol-led weaning may not be useful in the decision to wean.
In conventional pig production, suckling pigs are typically weaned between 3 and 5 weeks of age. This involves separation from the sow, dietary change, regrouping in a novel environment, which challenge welfare pigs. We investigated effects two weaning methods [conventional weaning: litters mixed weaner pen different size design (MOVE) vs. litter staying farrowing after removing sow (STAY)] gen...
