Increasing weaning age of piglets from 4 to 7 weeks reduces stress, increases post-weaning feed intake but does not improve intestinal functionality.
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...

TJF: SF Services, PO Box 5489, Little Rock, Arkansas, 72119; RCT, KH-D: W234 Veterinary Medicine, University of Missouri, Columbia, Missouri, 65211 eports concerning the effects of weaning age on pig performance in the nursery and the ability to eliminate pathogens conflict. Wiseman, et al., suggested that the ability to successfully eradicate pathogens increases as weaning age declines.1 Clark...
متن کاملEffects of dietary protein supply, weaning age and experimental enterotoxigenic Escherichia coli infection on newly weaned pigs: performance.
An experiment was conducted to investigate the effects of post-weaning dietary protein supply and weaning age on the performance of pigs in the absence of in-feed antimicrobial growth promoters (AGP) when artificially challenged with enterotoxigenic Escherichia coli (ETEC), a pathogen associated with post-weaning colibacillosis (PWC). The experiment consisted of a complete 2 × 2 × 2 factorial c...
متن کاملVoluntary food intake and reproduction
The underlying assumption I will make is that voluntary food intake is normally controlled so as to meet the requirements of the animal, especially for energy. This control is achieved by positive and negative feedbacks involving many pathways, in particular visceral receptors in communication with the central nervous system. Reproductive processes do not, on the whole, interfere seriously with...
