The early postnatal period is characterized by a great plasticity with critical windows in which any inadequate insult or intervention may be able to influence both positively and adversely postnatal growth and development. After birth the rat littermates enter the presuckling period (initial 6 hours terminated by the first nursing), characterized by transition from the amniotic fluid to the ai...

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...

A total of 28 litters (241 × 600, DNA) corresponding with 355 nursery pigs DNA; initially 13.0 lb) were used in 42-d trial (17-d pre-weaning and 24-d post-weaning). This was conducted to determine the effect providing a sensory attractant liquid (BlueLite Pro2Lyte; TechMix Global; Stewart, MN) suckling on underline sows after farrowing late lactation, weaning post-weaning feed intake growth. Tr...

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 ...

The objective of this study was to evaluate the effects of weaning age on dry matter intake (DMI), average daily gain (ADG), feed efficiency (FE), feed cost (FC) and benefit index (BI) of Holstein calves reared under organic farming system. Thirty two Holstein calves were divided into two treatments: early weaning (EW) vs. late weaning (LW). Calves in the both groups were provided with whole mi...

Food intake stimuli, including taste, somatosensory, and tactile stimuli, are received by receptors in the oral cavity, and this information is then transferred to the cerebral cortex. Signals from recently ingested food during the weaning period can affect synaptic transmission, resulting in biochemical changes in the cerebral cortex that modify gustatory and somatosensory nervous system plast...

Young animals can learn about flavors from the maternal diet that appear in the amniotic fluid and mother's milk, which may reduce neophobia for similarly flavored food types at weaning. Flavor learning may be beneficial for piglets, which after the rather abrupt weaning in pig husbandry frequently show a period of anorexia, reduced health, and stress-induced behaviors. We investigated the effe...

OBJECTIVE Automatic Tube Compensation (ATC) is a newly developed mechanical ventilatory support method. The aim of this study was to compare the ATC and the T-piece as a weaning method. METHODS Patients who were treated in ICU with mechanical ventilation for longer than 24 hours were included in this prospective clinical study. Fifty patients were divided into two groups for weaning, ATC or T...
