BACKGROUND Nitrogen isotope analysis of bone collagen has been used to reconstruct the breastfeeding practices of archaeological human populations. However, weaning ages have been estimated subjectively because of a lack of both information on subadult bone collagen turnover rates and appropriate analytical models. METHODOLOGY Temporal changes in human subadult bone collagen turnover rates we...

Functional maturation of the small intestine occurs during the weaning period in rats. It is known that this development is facilitated by glucocorticoid. However, the effect of glucocorticoid on morphological development of small intestine has yet to be clarified. The present study evaluated the morphological development and cell proliferation of the small intestine in adrenalectomized (ADX) r...

Analysis for back fat thickness (BFAT) and daily body weight gains from birth to the end of a performance test were conducted to find an optimal method for estimation of weaning age effects and to ascertain impacts of weaning age on the growth performance of purebred Berkshire pigs from a closed population in Korea. Individual body weights were measured at birth (B), at weaning (W: mean, 22.9 d...

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...

Abstract The backgrounding period is a post-weaning management strategy to add weight and build the health status in beef calves. This phase used prepare calves enter next of production supply chain. Weaning methods can be strategies reduce calf morbidity mortality feedlot. objective this study was assess growth performance based on weaning subsequent using commonly forage-based diets by Alabam...

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: Weaning is the most stressful event in pig’s life, resulting postweaning diarrhea and growth retardation. The supplementation of Advanced Digestion Enhancing Protein Plus Technology (ADEPPTTM), which contains iron-binding polypeptides non-starch polysaccharides, to nursery diets may reduce occurrence enhance performance weaning pigs. Objective: To evaluate effect ADEPPTTM on fecal s...

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...
