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, et al., observed that isolating pigs was as effective as medication and vaccination and they varied weaning age protocols in controlling the transmission of the pathogens (except for Haemophilus parasuis) that were investigated.2

Influence of photoperiod on the behavior and performance of newly weaned pigs with a focus on time spent at the feeder, feed disappearance, and growth
Materials and methods: Weaned pigs were allotted to daily photoperiods of 20 hours and 8 hours of light, respectively, for days 1 to 4 after weaning. Data were obtained from 234 pigs from 12 pens, resulting in n = 6 replicates per treatment. Behavior was observed during the initial 48 hours after weaning and on day 5 (when photoperiod was changed from 20 hours to 8 hours) in the prolonged light...
متن کاملPerformance and Measures of Stress in Lambs Weaned at 45 and 90 Days
A study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of Zandi lambs. The lambs were weaned at 45 and 90 days of age. The body weights and average daily gain (ADG) were monitored during the experimental period and 5 months of age. Cortisol, glucose, blood urea nitrogen (BUN) and lamb behavior (agitation, vocalization) were recorded bef...
متن کاملSegregated Early Weaning (SEW) of Pasture-farrowed Pigs
and Implications Segregated early weaning (SEW) works well with pasture-farrowed pigs. The SEW pasture-farrowed pigs weighed about the same as conventionally weaned pigs at 9 weeks of age with lower death losses (about 2% less). For the period 5Ð9 weeks of age the SEW pigs gained more rapidly and were more efficient converting feed to live gain than pigs weaned at 5 weeks of age and moved to an...
متن کاملEffects of Weaning Age on Growth and Blood Parameters of Replacing Holstein Calves Fed on a Restricted Step Up and Down Milk Feeding Program
The objective of this study was to investigate the effects of different early weaning programs on growth performance and blood parameters of dairy calves. To meet this objective, thirty Holstein calves with initial body weight of 36 ± 5 kg were randomly assigned at birth to one of the three weaning programs. Experimental groups were: 1) starter diet and whole milk from birth to 6 weeks and wean...

Materials and methods: This study was conducted as a randomized complete block design. Treatments were weaning at 12, 15, 18, and 21 days of age (N = 2272 pigs). Each block was an off-site nursery, with four replicates (pens) of each treatment in each of four blocks. All pigs in a block were weaned from a 7300-head sow farm on the same day (Day 0). Each pen was observed for 15 minutes on Days 7...
