Two experiments were conducted to evaluate the effects of dietary Zn and Fe supplementation on mineral excretion, body composition, and mineral status of nursery pigs. In Exp. 1 (n = 24; 6.5 kg; 16 to 20 d of age) and 2 (n = 24; 7.2 kg; 19 to 21 d of age), littermate crossbred barrows were weaned and allotted randomly by BW, within litter, to dietary treatments and housed individually in stainless steel pens. In Exp. 1, Phases 1 (d 0 to 7) and 2 (d 7 to 14) diets (as-fed basis) were: 1) NC… Expand
Influence of a microbial phytase and zinc oxide on young pig growth performance and serum minerals.
TLDR
Phytase supplementation improved ADG in Ca- and P-adequate diets regardless of the level of ZnO supplemented, which may be attributed to the reduction of phytate as an antinutrient. Expand
Effects of Iron Glycine Chelate on Growth, Tissue Mineral Concentrations, Fecal Mineral Excretion, and Liver Antioxidant Enzyme Activities in Broilers
TLDR
It is indicated that addition with Fe-Gly could improve growth performance and iron tissue storage and improves the antioxidant status of broiler chickens. Expand

TLDR
Zinc oxide provided a feasible alternative to in-feed antibiotics to improve growth in post-weaning pigs, and its reduction in diets due to potential environmental pollution will have to be negated by alternative feed additives and management strategies in order to prevent economic losses. Expand
Moderate tetrabasic zinc chloride supplementation improves growth performance and reduces diarrhea incidence in weaned pigs
TLDR
The TBZC is a potential alternative to ZnO in weaned pig diets and shows the greatest total antioxidant capacity and glutathione peroxidase activities in liver of pigs. Expand
The effect of iron glycine chelate on tissue mineral levels , fecal mineral concentration , and liver antioxidant enzyme activity in weanling pigs
Twenty-four weaning pigs were used to evaluate the effects of iron glycine chelate (Fe-Gly) on tissue mineral levels, fecal mineral concentration and liver antioxidant enzyme activities of weanlingExpand
Effect of the dietary alfalfa on iron balance in weaned piglets
TLDR
Experimental evidences show that the dietary alfalfa given to the weaned piglets influenced significantly Fe balance because the important supply of iron increased the coefficient of intestinal absorption from the ingesta. Expand
Effects of Dietary Iron Levels on Growth Performance, Hematological Status, Liver Mineral Concentration, Fecal Microflora, and Diarrhea Incidence in Weanling Pigs
TLDR
It is concluded that increasing the dietary iron levels in piglets improved their hematological status and liver Fe content; however, higher dietary Fe levels might also be associated with the increased diarrhea incidence. Expand
Comparison of organic and inorganic zinc sources to maximize growth and meet the zinc needs of the nursery pig.
TLDR
The data show that to maximize growth, health, and well-being, 75 mg/kg of organic Zn in a complex nursery diet benefits today's fast growing pigs with a very high lean tissue composition. Expand
Effects of copper sulfate, tri-basic copper chloride, and zinc oxide on weanling pig performance.
TLDR
These 3 experiments show the advantages of including both Cu and Zn in the diet for 28 d postweaning; however, as evident in Exp. 3, when 3,000 mg/kg of Zn was added early and 125 mg/ kg of Cu was added late, performance was similar or numerically greater than when both were used for 42 d. Expand
The Effect of Peripheral Administration of Zinc on Food Intake in Rats Fed Zn-adequate or Zn-deficient Diets
TLDR
The present studies suggested that zinc administration did not affect short-term food intake in rats even in the zinc-deficient ones; the reduced food intake induced by zinc deficiency was fprobably associated with the depression in thyroid hormones. Expand

Effects of dietary iron supplementation on growth performance, hematological status, and whole-body mineral concentrations of nursery pigs.
TLDR
Results suggest that Fe contributed by feed ingredients was not sufficient to maintain indices of Fe status and the lessening of a pig's Fe stores during this rapid growth period may result in the occurrence of anemia during the subsequent grower and finisher periods. Expand
Growth promotion effects and plasma changes from feeding high dietary concentrations of zinc and copper to weanling pigs (regional study).
TLDR
The data indicate that pharmacological additions of 3,000 ppm Zn (oxide) or 250 ppm Cu (sulfate) stimulate growth beyond that derived from intakes of Zn and Cu that meet nutrient requirements. Expand
Effect of feeding organic and inorganic sources of additional zinc on growth performance and zinc balance in nursery pigs.
TLDR
In conclusion, feeding 3,000 ppm added Zn as ZnO improves nursery pig performance; however, under certain nursery conditions the use of 500 ppm addedZn as SQM-Zn may also enhance performance. Expand
Effects of Pharmacological Levels of Zinc as Zinc Oxide on Fecal Zinc and Mineral Excretion in Weanling Pigs1
Abstract Eighteen weanling crossbred barrows (7.3 kg; 22 d of age) were used in a randomized complete block design to evaluate the effect of supplemental Zn from ZnO on fecal excretion of Zn andExpand
Early- and traditionally weaned nursery pigs benefit from phase-feeding pharmacological concentrations of zinc oxide: effect on metallothionein and mineral concentrations.
TLDR
Both early- and traditionally weaned pigs need to be fed pharmacological concentrations of Zn provided as ZnO for a minimum of 2 wk immediately after weaning to enhance growth. Expand
Bioavailability of zinc from inorganic and organic sources for pigs fed corn-soybean meal diets.
Two experiments were conducted with pigs 1) to determine the effect of supplemental Zn on growth performance, bone Zn, and plasma Zn in pigs fed Zn-unsupplemented, corn-soybean meal diets and 2) toExpand
Zinc concentration in tissues and performance of weanling pigs fed pharmacological levels of zinc from ZnO, Zn-methionine, Zn-lysine, or ZnSO4.
TLDR
Performance was not enhanced by feeding pharmacological levels of zinc after weaning, although serum and tissue Zn concentrations were increased. Expand
Effects of the interrelationship between zinc oxide and copper sulfate on growth performance of early-weaned pigs.
TLDR
Feeding 3,000 ppm of Zn from ZnO is a viable means of improving nursery pig performance, but additive responses to growth-promotant levels of CuSO4 (250 ppm Cu) were not observed. Expand
Zinc-amino acid complexes for swine.
TLDR
The data suggest that the Zn sources used are of similar biological value and do not support the theory that picolinic acid aids Zn absorption. Expand
Concentration of minerals in tissues of pigs from dams fed different levels of dietary zinc.
TLDR
First- and second-parity pigs from sows on the highest Zn supplementation level had higher Fe stores in the liver, higher Zn concentrations in the Liver, kidney and pancrease, and higher Cu levels in the kidney compared with pigs from Sow on the other treatments. Expand
