One hundred and eighty individually housed piglets with an initial body weight of 7.63 ± 0.98 kg (at 28 days age) were fed a diet containing either 153, 493, 1022, 1601, 2052 or 2407 mg zinc/kg (added Zn as zinc oxide; ZnO) from day 0-21 post weaning to determine the optimal level for weaned piglets. Body weight, feed intake faecal scores recorded, blood samples collected. Dietary content quadratically affected both gain in first two weeks, approximately 1400 Zn/kg 400 mg/day levels. The...
Excessive dietary Zn is excreted through feces in pigs. Spreading pig slurry containing high concentrations to fields leads increased risk of antibiotic resistance gene development soil bacteria and has a negative impact on fertility. Data from 10 published studies with weaned pigs during the first 6 wks post-weaning (PW) was included meta-regression analysis develop model for relationship between daily intake excretion. The excretion linearly (P < 0.01), formulation added (source Zn) had no...
Abstract This study investigated the impact of an enterotoxigenic Escherichia coli (ETEC) F18 challenge on newly weaned pigs when fed one three Zn levels (150, 1,400, or 2,500 ppm) performance, status, ETEC shedding, and diarrhea. The was hypothesized to have a more pronounced negative diet containing 150 ppm compared 1,400 for 14 d after weaning. included 72 susceptible at ~28 age (d 0 study). were distributed according initial weight litter dietary levels. Half challenged with 1 2. reduced...
The bioavailability of dietary zinc (Zn) in pigs may differ according to the Zn source and is affected by other components diet. aim was determine biomarkers (apparent total tract digestibility serum status) following six different sources added their effect on performance faecal consistency score piglets 0-3 weeks after weaning day 28. were oxide (ZnO), sulfate (ZnSO4), porous ZnO, Zn-glycinate, amino acid-bound hydroxy covalent-bound at 100 mg/kg (ZnO ZnSO4 also 1000 mg/kg), a eight...
Focus remains on reducing the excretion of surplus zinc (Zn) from pigs through manure due to environmental and public health concerns. Growing–finishing may need less dietary Zn than current EU legislation allows what is typically applied farms. The aim this study was evaluate effect three levels productivity, homeostasis, status in growing fed a grain soybean meal-based diet with high inclusion phytase (1000 units). Ninety were offered 1431 83 ppm total weeks 0–2 2–6 post-weaning,...
Abstract The Zn requirement of pigs immediately after weaning is more investigated compared to the in growth period between 10 and 30 kg. Unabsorbed excessive dietary excreted mainly through feces, spreading pig slurry fields can cause environmental issues because high levels impair plant contribute development antimicrobial resistance genes microorganisms. Therefore, precise knowledge requirements recommendations important. present study optimal content for 10- 30-kg pigs. used 150 weaned...
