During the introduction of solid food (usually indicated as the weaning period), infant and caregiver have to adjust their feeding interactions to a completely changed feeding context. In this paper, we argue that these adjustments can be seen as a complex process in which many factors are involved. As a result of these complex interactions, eating behavior can be highly variable between infant...

This prospective study compared two weaning modalities in COPD patients requiring mechanical ventilation (MV) for acute respiratory failure. Nineteen patients with COPD were studied when their precipitating illness was controlled. Although they satisfied the conventional bedside weaning criteria, they could not tolerate any reduction in the respirator rate below 10 cycles/min. At this time, pat...

This study evaluated the effect of feeding low protein (LP) diets for 7 or 14 d after weaning or a high protein (HP) diet for 14 d after weaning on postweaning diarrhea (PWD), indices of protein fermentation, and production in pigs infected or not infected per os with an enterotoxigenic strain of Escherichia coli. A total of 72 female pigs weaned at aged 21 d with initial BW of 5.9 +/- 0.12 kg ...

Porcine epidemic diarrhea virus (PEDV) is an important pathogen that has a significant economic impact on the swine industry by imposing a high rate of mortality in suckling piglets. However, limited information on the productivity values of gilts and sows infected with PEDV is available. Here, we evaluate the productivity index in gilts and sows during the 1-year period before (19 January 2013...

Pigs from one farrowing group in which gilts were bred to farrow pigs that would be either 14 or 21 d of age at weaning, were divided into older and younger age groups (108 pigs per group) and penned 12 pigs per pen in a wean-to-finish facility. At the end of the nursery phase, half the pigs in each age group were removed, rerandomized, and commingled for the finishing phase. The other half rem...

Gastrointestinal nematode (GIN) infections have an important negative impact on small ruminant production. The selection of genotypes resistant to these parasitic infections is a promising alternative control strategy. Thus, resistance against GIN is an important component of small ruminant breeding schemes, based on phenotypic measurements of resistance in immune mature infected animals. In th...

The influence of heated mash on growth and feeding behavior of newly weaned piglets was investigated. An automatically ventilated nursery with 4 identical pens was used. Twenty piglets weaned at 21 d were housed in each pen. The experiment was repeated 3 times. In total, data were obtained from 240 piglets of 12 pens. The pens were provided with a sensor-controlled, automatic feeding device, wh...

BACKGROUND Although the weaning classification based on the difficulty and duration of the weaning process has been evaluated in the different type of intensive care units (ICUs), little is known about clinical outcomes and validity among the three groups in medical ICU. The objectives of this study were to evaluate the clinical relevance of weaning classification and its association with hospi...

Weaning of beef calves is usually done abruptly and early compared to the natural weaning of the species, and is associated with simultaneous exposure of calves to a range of social and environmental stressors. Behavioural and physiological responses to weaning indicate detrimental effects on the welfare of these animals. The development and assessment of weaning methods aiming at reducing or a...

ABSTRACT: This study measured milk and solid feed intake in pre- weaning period postweaning of Nellore calves, to correlated them with performance traits ingestive behavior animals classified as most least efficient. During pre phase, efficiency was evaluated 51 cow-calf pairs from 21±5 days after calving until weaning. post-weaning only male calves (n=23) were evaluated. Pre-weaning estimated ...
