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...

This study tested the hypothesis that late weaning and the availability of creep feed during the suckling period compared with early weaning, improves feed intake, decreases stress and improves the integrity of the intestinal tract. In this study with 160 piglets of 16 litters, late weaning at 7 weeks of age was compared with early weaning at 4 weeks, with or without creep feeding during the su...

The aim of this study was to evaluate how the inclusion a blend essential oils in milk replacer (MR) affects different outcomes dairy heifers. evaluated: feed intake, performance, body development, blood cells and metabolites, insulin-like growth factor-1 (IGF-1), rumen fermentation, fecal scores, respiratory scores. All were evaluated during pre-weaning (4–60 d age), carry-over effects post-we...

Objectives Weaning is a key life history milestone for mammals that represents both the end of nutritional investment from perspective mothers and start complete independence infants. The age at weaning may vary depending on ecological, social, demographic factors experienced by mother infant. Bwindi mountain gorillas live in different environmental conditions have longer interbirth intervals t...

<p>In order to establish a lighting regime suitable for rabbit farms in East China, the effects of schedule, intensity and colour on reproductive performance does were evaluated by three experiments, respectively. In experiment 1, exposed different schedules: 16L:8D-continuous, 16L:8D-18d (6 d before artificial insemination (AI) 12 post-AI), 16L:8D-6d AI day AI) 12L:12D-continuous. 2, lig...

introduction lamb production is the largest part of income in sheep industry. therefore, the mortality rate of lambs is a key factor in profit of the sheep breeding. mortality rate of lambs (or lamb mortality rate) in different breeds of sheep under different climatic conditions is varying from 15% to 50% and an average of 9% to 20% has been reported. survival rate is a combination trait that i...

IMPORTANCE Patients requiring prolonged mechanical ventilation (>21 days) are commonly weaned at long-term acute care hospitals (LTACHs). The most effective method of weaning such patients has not been investigated. OBJECTIVE To compare weaning duration with pressure support vs unassisted breathing through a tracheostomy collar in patients transferred to an LTACH for weaning from prolonged ve...

Variance and covariance components were estimated for yearling scrotal circumference and weaning weight from Limousin field data. Records of 8.226 bulls were used to evaluate 584 sires and 653 maternal grandsires. Data included all herdbook records of bulls with a recorded scrotal circumference and their weaning contemporaries. Analyses were performed by restricted maximum likelihood techniques...

Weaning from mechanical ventilation was categorised as simple, difficult or prolonged by an international task force of the American Thoracic Society/European Respiratory Society/European Society of Intensive Care Medicine/Society of Critical Care Medicine/Sociéte de Réanimation de Langue Française in 2007. This new classification has not been tested in clinical practice. The objective of the p...

Under commercial conditions, weaning of piglets is associated with social, environmental and dietary stress. Consequently, small-intestinal barrier and absorptive functions deteriorate within a short time after weaning. Most studies that have assessed small-intestinal permeability in pigs after weaning used either Ussing chambers or orally administered marker probes. Paracellular barrier functi...
