Abstract
Feed costs present a major burden in animal production for human consumption, representing a key opportunity for cost reduction and profit improvement. Nanotechnology offers potential to increase productivity by creating higher-quality and safer products. The feed sector has benefited from the use of nanosystems to improve the stability and bioavailability of feed ingredients. The development of nanotechnology products for feed must consider the challenges raised by biological barriers as well as regulatory requirements. While some nanotechnology-based products are already commercially available for animal production, the exponential growth and application of these products requires further research ensuring their safety and the establishment of comprehensive legislative frameworks and regulatory guidelines. Thus, this article provides an overview of the current state of the art regarding nanotechnology solutions applied in feed, as well as the risks and opportunities aimed to help researchers and livestock producers.

[PMID: 37969343 PMCID: PMC10640932 DOI: 10.5187/jast.2023.e28] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/12/2023] [Accepted: 03/17/2023] [Indexed: 11/17/2023]
Abstract
The aim of this study was to investigate the effect of incorporating black soldier fly (BSF) larvae and its processed form as an alternative source of protein to fish meal (FM) on the digestibility of amino acids (AA) in weaned pigs. Four cannulated pigs with an initial bodyweight of 13.25 ± 0.25 kg and aged 30 days were subjected to a 4 × 4 Latin square design with three treatments, as well as a nitrogen-free treatment. The diets used for each treatment consisted of a FM diet, a diet containing BSF larvae meal (BSFM), and a diet containing extruded BSF (BSFE). The study was conducted over four stages, with a total duration of 28 days. The apparent ileal digestibility (AID) of protein was higher in the FM treatment compared with the BSFM. Among essential AA, the AID of Arg, His, Leu, and Thr were higher in the FM compared with the BSFM and BSFE. A greater AID of Ile and Phe was observed in pigs in the FM treatment compared with the BSFM. The average AA digestibility did not show any difference between treatments. Among non-essential AA, the AID of Ala (p = 0.054) and Glu (p = 0.064) tended to be increased in the FM compared with the BSFM. Among essential AA, the standardized ileal digestibility (SID) of Arg, His, Ile, and Leu were higher in the FM compared with the BSFM. Among non-essential AA, the SID of Cys (p = 0.074) tended to be increased in the FM compared with the BSFM. In conclusion, the processing and thermal conditioning techniques utilized for BSF larvae meal showed a tendency for increased AA digestibility. Therefore, when formulating a diet, it is important to take into account the difference in AA digestibility between FM and BSFM.

Porcine Health Manag 2023; 9:32. [PMID: 37420289 DOI: 10.1186/s40813-023-00327-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 06/21/2023] [Indexed: 07/09/2023] Open
Abstract
BACKGROUND Small peptide chelated iron (SPCI), a novel iron supplementation in pig diets, owns growth-enhancing characteristics. Although a number of researches have been performed, there is no clear-cut evidence to show the exact relationship between the dose and effects of small peptide chelated minerals. Therefore, we investigated the effect of dietary supplementation of SPCI at different doses in the growth performance, immunity, and intestinal health in weaned pigs. METHODS Thirty weaned pigs were randomly assigned into five groups and feed with basal diet or the basal diet containing 50, 75, 100, or 125 mg/kg Fe as SPCI diets. The experiment lasted for 21 d and on day 22, blood samples were collected 1 h later. The tissue and intestinal mucosa samples were collected following. RESULTS Our results showed that the feed to gain ratio (F:G) decreased with different levels of SPCI addition (P < 0.05). The average daily gain (ADG) (P < 0.05) and digestibility of crude protein (P < 0.01) decreased with 125 mg/kg SPCI addition. With dietary different levels of SPCI addition, the serum concentrations of ferritin (quadratic, P < 0.001), transferrin (quadratic, P < 0.001), iron content in liver (quadratic, P < 0.05), gallbladder (quadratic, P < 0.01) and fecal (quadratic, P < 0.01) increased quadraticly. While the iron content in tibia (P < 0.01) increased by 100 mg/kg SPCI supplementation. Dietary 75 mg/kg SPCI addition increased the serum insulin-like growth factor I (IGF-I) (P < 0.01) and SPCI (75 ~ 100 mg/kg) addition also increased the serum content of IgA (P < 0.01). The serum concentrations of IgG (quadratic, P < 0.05) and IgM (quadratic, P < 0.01) increased quadraticly by different levels of SPCI supplementation. Moreover, different levels of SPCI supplementation decreased the serum concentration of D-lactic acid (P < 0.01). The serum glutathione peroxidase (GSH-Px) (P < 0.01) elevated but the malondialdehyde (MDA) (P < 0.05) decreased by 100 mg/kg SPCI addition. Interestingly, SPCI supplementation at 75 ~ 100 mg/kg improved the intestinal morphology and barrier function, as suggested by enhanced villus height (P < 0.01) and villus height/crypt depth (V/C) (P < 0.01) in duodenum, as well as jejunum epithelium tight-junction protein ZO-1 (P < 0.01). Moreover, SPCI supplementation at 75 ~ 100 mg/kg increased the activity of duodenal lactase (P < 0.01), jejunal sucrase (P < 0.01) and ileal maltase (P < 0.01). Importantly, the expression levels of divalent metal transporter-1(DMT1) decreased with different levels of SPCI addition (P < 0.01). In addition, dietary SPCI supplementation at 75 mg/kg elevated the expression levels of critical functional genes such as peptide transporter-1(PePT1) (P = 0.06) and zinc transporter 1 (ZnT1) (P < 0.01) in ileum. The expression levels of sodium/glucose co-transporter-1 (SGLT1) in ileum (quadratic, P < 0.05) increased quadraticly by different levels of SPCI addition and amino acid transporter-1 (CAT1) in jejunum(P < 0.05) also increased by 100 mg/kg SPCI addition. CONCLUSIONS Dietary SPCI supplementation at 75 ~ 100 mg/kg improved growth performance by elevated immunity and intestinal health.

Choi Y, Hosseindoust A, Ha SH, Kim J, Min Y, Jeong Y, Mun J, Sa S, Kim J. Effects of dietary supplementation of bacteriophage cocktail on health status of weanling pigs in a non-sanitary environment. J Anim Sci Biotechnol 2023; 14:64. [PMID: 37150809 PMCID: PMC10165815 DOI: 10.1186/s40104-023-00869-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 03/14/2023] [Indexed: 05/09/2023] Open
Abstract
BACKGROUND The study evaluated the effects of bacteriophage cocktail (BP) and ZnO administered during weaning time for piglets exposed to a non-sanitary environment. The bacteriophages were designed to eliminate Escherichia coli (K88, K99 and F41), Salmonella (typhimurium and enteritidis), and Clostridium perfreingens (types A and C). Forty 21-day-old crossbreed piglets were assigned to four treatments, including the PC (sanitary environment), NC (non-sanitary environment), BP (NC plus 108 pfu/kg BP), and ZO (NC plus 2,500 mg/kg ZnO). Piglets in the NC, BP and ZO were kept in a non-sanitary environment for 14 d, which was contaminated with the feces of infected pigs. RESULTS Pigs in the BP and ZO treatments had a higher final body weight compared with the NC. The NC treatment showed the highest concentration of inflammatory cytokines including interleukin (IL)-1β, IL-6 and tumor necrosis factor-α in the plasma. The administration of BP and ZO showed lower myeloperoxidase concentrations compared with the NC. The NC treatment showed a lower concentration of superoxide dismutase in serum compared with the PC. Among the treatments in non-sanitary environment, the NC treatment showed a higher concentration of malondialdehyde compared with the ZO. The PC treatment showed a lower concentration of butyric acid in the feces compared with the BP treatment. Among non-sanitary treatments, the villus height in the duodenum was greater in the BP and ZO compared with the NC. The lower abundance of Proteobacteria phylum was observed in the BP and PC treatments compared with the NC. The highest relative abundance of Eubacterium was recorded in the BP treatment. The abundance of Megasphaera and Schwartzia was higher in the NC pigs compared with the BP piglets. The abundance of Desulfovibrio was lower in the supplemented treatments (BP and ZO) compared with non-supplemented (NC and PC). The abundance of Cellulosilyticum genera was higher in the BP and ZO treatments rather than in the NC. The piglets in the NC treatment had the highest abundance of Escherichia-Shigella, followed by the PC and ZO treatments. CONCLUSION In conclusion, these results suggest that the supplementation of bacteriophage cocktail could effectively control Proteobacteria phylum, Clostridium spp. and coliforms population and mitigated the adverse influences of weaning stress in piglets.

Improved Growth Performance, Antioxidant Status, Digestive Enzymes, Nutrient Digestibility and Zinc Bioavailability of Broiler Chickens with Nano-Sized Hot-Melt Extruded Zinc Sulfate. Biol Trace Elem Res 2022; 200:1321-1330. [PMID: 33954866 DOI: 10.1007/s12011-021-02747-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Accepted: 04/28/2021] [Indexed: 11/29/2022]
Abstract
This experiment was conducted to investigate the effect of the supplementation of hot-melt extrusion (HME) processed zinc sulfate (ZnSO4) on the growth performance, antioxidative activity, pancreatic digestive enzyme, small intestinal morphology, nutrient digestibility, and Zn content in broilers. The chicks were allocated to three treatments, each of which had five replicates of 15 chicks per replicate. The broiler chickens were assigned to three dietary treatments: the control (without supplemental Zn), IN-Zn (ZnSO4, 80 mg/kg), and HME-Zn (HME processed ZnSO4 as nano-Zn, 80 mg/kg). The broilers fed diets supplemented with 80 mg/kg of HME-Zn improved the BWG (P < 0.05) and FCR (P < 0.05) compared to the broilers fed the control and IN-Zn diets in phase 2. The Zn supplementation significantly enhanced the superoxide dismutase (SOD) activity in the serum (P < 0.05) and liver (P < 0.05), and HME-Zn supplementation significantly increased the SOD in the liver compared to the IN-Zn supplementation. Reduced malondialdehyde (MDA) concentration was seen with the Zn supplementation compared to the control (P < 0.05). The chickens fed diets supplemented with the HME-Zn had higher activity of amylase (P < 0.05) and trypsin (P < 0.05) than those of the chickens fed the control and IN-Zn diets. The villus height (VH) in the duodenum (P < 0.05) and jejunum (P < 0.05) increased with the ZnSO4 and HME-Zn supplementation compared to the control. The VH and crypt depth rate (VH:CD) in the jejunum improved with the HME-Zn compared to the control (P < 0.05). The HME-Zn significantly increased the apparent ileal digestible crude protein (CP) (P < 0.05) and energy corrected by nitrogen (AIDEn) (P < 0.05) compared to the control or IN-Zn. In phases 1 and 2, the HME-Zn significantly increased Zn concentration in the liver and tibia compared to control and IN-Zn (P < 0.05). The excretion of Zn was significantly decreased in the HME-Zn compared to the IN-Zn (P < 0.05). In conclusion, supplementation of 80 mg/kg of HME-Zn in diets improved the growth performance, antioxidative activity, pancreatic enzyme activity, intestinal villus height, and nutrient digestibility with the improved Zn bioavailability in broilers.

pharmacological doses of ZnO in weanling pigs. JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2022; 64:70-83. [PMID: 35174343 PMCID: PMC8819322 DOI: 10.5187/jast.2022.e2] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 01/07/2022] [Accepted: 01/08/2022] [Indexed: 12/18/2022]
Abstract
A set of studies was performed to determine the influence of dietary ZnO
concentration and source during two phases (days 0 to 14 and days 15 to 28).
Experiment 1: 168 weaned piglets were allocated to four treatment groups in six
replicates. The treatments included a basal diet without ZnO supplementation
(control), 2,500 mg ZnO/kg (In2500), 500 mg nano-ZnO/kg (N500), and 150 mg
nano-ZnO/kg (N150). Experiment 2: 168 weaned piglets were divided into three
treatment groups with eight replicates. The treatments included control, In2500,
N300, and 150 mg nano-ZnO/kg (N150). An in vitro trial showed that the growth of
Listeria monocytogenes, Escherichia coli, and
Salmonella typhimurium was inhibited when exposed to 300
and 500 ppm of ZnO after 24 h of incubation. In experiment 1, the average daily
gain (ADG) by the pigs was improved in the N500 and IN2500 treatment groups.
Colonization of coliforms and Clostridium spp. significantly
decreased in the pigs fed the N500 and IN2500 diets in phase 1. The total plasma
antioxidant capacity was greater in the IN2500 and N500 treatment groups than in
the control. Superoxide dismutase (SOD) activity was greater in pigs fed the
IN2500 (phase 1) or the IN2500 and N500 (phase 2) diets than in the control and
N150 treatment group. In experiment 2, pigs in the N300 treatment group showed a
higher ADG and lower fecal score colonization of coliforms and
Clostridium spp. compared with those in the N150 treatment
group. In conclusion, nano-ZnO at a dose of 300 ppm showed the same growth as
the pharmacological dose of Zn. This provides an option to the pharmacological
dose.

Abstract
Iron deficiency is the most common mammalian nutritional disorder. However, among mammalian species iron deficiency anemia (IDA), occurs regularly only in pigs. To cure IDA, piglets are routinely injected with high amounts of iron dextran (FeDex), which can lead to perturbations in iron homeostasis. Here, we evaluate the therapeutic efficacy of non-invasive supplementation with Sucrosomial iron (SI), a highly bioavailable iron supplement preventing IDA in humans and mice and various iron oxide nanoparticles (IONPs). Analysis of red blood cell indices and plasma iron parameters shows that not all iron preparations used in the study efficiently counteracted IDA comparable to FeDex-based supplementation. We found no signs of iron toxicity of any tested iron compounds, as evaluated based on the measurement of several toxicological markers that could indicate the occurrence of oxidative stress or inflammation. Neither SI nor IONPs increased hepcidin expression with alterations in ferroportin (FPN) protein level. Finally, the analysis of the piglet gut microbiota indicates the individual pattern of bacterial diversity across taxonomic levels, independent of the type of supplementation. In light of our results, SI but not IONPs used in the experiment emerges as a promising nutritional iron supplement, with a high potential to correct IDA in piglets.

Abstract
To study the role of hot-melt extruded (HME) selenium (Se) and in the lactating sows' reproductive performance and litter growth, a total of 60 crossbred sows (Yorkshire × Landrace; average body weight, 245.3 kg) were allotted to one of four treatments according to a 2 × 2 factorial arrangement. The performance of lactating sows was investigated in the different average room temperatures (high temperature (HT), 28.1 °C vs. low temperature (LT), 24.6 °C), and different selenium sources (INO, 0.15 mg common sodium selenite/kg diet; HME, 0.15 mg nano-sodium selenite/kg diet) during the summer season. At days 10 and 21, the serum glutathione peroxidase (GPx) activity and Se concentration were greater in lactating sows fed HME compared with sows fed INO diet. The concentration of Se in the serum was greater in piglets from the HME treatment compared with piglets from the INO treatment. The HT treatment had a significantly higher body weight loss, backfat thickness loss, and weaning-to-estrus interval. The piglets' survivability, total weight gain, daily feed intake, and average daily gain during the lactation were greater in the LT sows compared with the HT sows. A higher blood cortisol concentration was observed in the HT sows compared with the LT. Selenium contents of milk at days 10 and 21 postpartum were increased by dietary supplementation of HME. In conclusion, the results of the present study demonstrated that there are no performance differences between sows fed different Se sources; however, HME supplementation increased serum and milk Se content, resulting in increased serum GPx concentration in sows and a greater serum Se in the litters.

Abstract
1. Mineral excretion is an issue in the poultry industry. The use of micro minerals in nano form can increase bioavailability and decrease excretion rate. However, information concerning the bioavailability of nano manganese (Mn) in broiler chicks is limited.2. This experiment studied the influences of hot-melt extrusion (HME)-processed manganese sulphate on body weight gain, Mn bioavailability, nutrient digestibility and meat quality in broiler chicks fed a corn-soybean meal-based diet as a starter and grower phase. A total of 700 birds (Ross 308, 1-day-old) were randomly placed in 35 cages (20 birds per cage). The broiler chicks were fed one of seven experimental diets, which consisted of a control (without supplemental Mn), different levels of MnSO4 (IN-Mn60; 60, 120, and 200 mg/kg), or HME MnSO4 (HME-Mn; 60, 120, and 200 mg/kg).3. There was an increased serum Mn content in broilers fed diet supplemented with HME-Mn. In the grower phase, increased dietary Mn levels elevated the concentrations in the serum, liver, and tibia. There were increases in the excreta Mn content of broilers fed increasing levels. The supplementation of HME-Mn showed a lower percentage of abdominal fat compared with the IN-Mn treatment diets. Supplementation with HME-Mn decreased intramuscular fat compared with the diets supplemented with IN-Mn. The supplementation of HME-Mn decreased the thiobarbituric acid reactive substances (TBARS) at d 6 of age. The HME-Mn source showed a greater decrease in TBARS compared with the IN-Mn treatment.4. In conclusion, HME processing increased bioavailability and could be used as an environmentally friendly method to facilitate lower levels of Mn in the diet of broiler chickens.

Abstract
This study was conducted to investigate the effects of hot-melt extrusion (HME)-processed copper (Cu) sulfate supplementation on the growth performance, gut microbiota, metabolic function of Cu, and bioavailability of Cu in weanling pigs fed a corn-soybean meal basal diets. A total of 180 piglets (Yorkshire × Landrace × Duroc) of mixed-sex randomly were allotted to six treatments on the basis of initial average body weight (6.36 ± 0.39 kg) to six dietary treatments. There were six replicates in each treatment with 5 pigs per replicates. The dietary treatments included levels of CuSO4 (IN6, 6 mg Cu/kg diets; IN125, 125 mg Cu/kg diets), nano-CuSO4 (HME6, 6 mg Cu/kg diets; HME65, 65 mg Cu/kg diets; and HME125, 125 mg Cu/kg diets), and Cu-methionine (ORG125, 125 mg Cu/kg diets). The weanling pigs fed diets supplemented with the HME65 and HME125 showed a greater body weight and feed intake compared with IN6 and IN125 (P < 0.05). The weaning pigs fed diets supplemented with the HME125 showed the highest digestibility of gross energy in phase 1 and phase 2 (P < 0.05). The supplementation of HME125 significantly reduced the Escherichia coli (E.coli) in cecum and colon (P < 0.05). The supplementation of HME65 showed statistically equivalent effect on reduction of E. coli in the cecum and colon compared with IN125 and ORG125 treatments. The villus height in duodenum and jejunum of piglets in HME65 and HME125 treatments were higher than ORG125, HME6, IN6, and IN125 (P < 0.05). The gene expression of Atox1 was upregulated in IN125, HME125, and ORG125 treatments (P < 0.05). The expression of Sod1 was increased in IN125 treatment compared with IN6 treatment (P < 0.05). The HME125 treatment had the highest gene expression of ghrelin (P < 0.05). The Cu concentration of serum and liver was higher in the HME125 treatment than the HME6, IN6, and IN125 treatments (P < 0.05). The HME125 and ORG125 treatments showed a lower fecal Cu compared with IN125 treatment (P < 0.05). Taken together, these results suggest that the HME65 can be an alternative to IN125 in weanling pigs due to the greater overall average daily gain, improved villus height, and higher bioavailability.

Abstract
Objective This study was conducted to evaluate the effects of the supplementation of diets of broiler chickens with hot-melt extruded CuSO4 (HME-Cu) on their growth performance, nutrient digestibility, gut microbiota, small intestinal morphology, meat quality, and copper (Cu) bioavailability. Methods A total of 225 broilers (Ross 308), one-day old and initial weight 39.14 g, were weighed and distributed between 15 cages (15 birds per cage) in a completely randomized experimental design with 3 treatments (diets) and 5 replicates per treatment. Cages were allotted to three treatments including control (without supplemental Cu), IN-Cu (16 mg/kg of CuSO4), and HME-Cu (16 mg/kg of HME processed CuSO4). Results The HME-Cu treatment tended to increase the overall body weight gain (p<0.10). The apparent digestibility of Cu was increased by supplementation of HME-Cu at phase 2 (p<0.05). The Escherichia coli count in cecum tended to decrease with the supplementation with Cu (p<0.10). In addition, the HME-Cu treatment had a higher pH of breast meat than the control and IN-Cu treatments (p<0.05). Significant increases in the cooking loss, water-holding capacity, and lightness in the breast were observed in the HME-Cu treatment compared to the control (p<0.05). The Cu content of excreta increased with the Cu supplementation (p<0.05). The concentration of excreta Cu in broilers was decreased in the HME-Cu compared to the IN-Cu in phase 2 (p<0.05). The Cu concentration in the liver was increased with the HME-Cu supplementation, compared with the control diets (p<0.05). Conclusion This study showed that HME-Cu supplementation at the requirement level (16 mg/kg diets) in broiler diets did not affect the growth performance and the physiological function of Cu in broilers. However, supplementation of Cu in HME form improved the meat quality and the bioavailability of Cu.

Abstract
This study was aimed to investigate the Cu bioavailability, growth response,
digestibility of nutrients, and blood metabolites of broiler chicks fed
CuSO4 in nano or common forms. A total of 720 broiler chickens
were distributed between eight treatments according to a completely randomized
design. There were 8 treatments and 6 replicates in each treatment with 15
birds/replicate. The treatments were divided into common copper sulfate at the
doses of 16 ppm, 40 ppm, 80 ppm, and 120 ppm (INO) and hot-melt extruded copper
sulfate at the doses of 16 ppm, 40 ppm, 80 ppm, and 120 ppm (HME-Cu). The
experiment was operated for 35 days in 2 phases (phase 1, d 0 to 14; and phase
2, d 15 to 35). No significant differences were shown in growth performance,
feed intake, FCR, and nutrient digestibility among the treatments. The
concentration of Cu in the serum was increased in the HME-Cu broilers compared
with the INO broilers at phase 2. A linear increase was observed in the
concentration of Cu in the liver in broilers fed INO diets, however, no
significant differences were observed by the supplementation of HME-Cu levels.
The linear increase was detected in the content of Cu in excreta in the INO and
HME-Cu treatments by increasing the dietary Cu content. The HME-Cu treatments
showed a lower Cu concentration in the excreta compared with the INO treatments.
The higher bioavailability of Cu in HME form can decrease the recommended dose
of Cu in broiler diets.

Abstract
This study investigated the different addition levels of iron (Fe) in growing-finishing pigs and the effect of different Fe levels on growth performance, hematological status, intestinal barrier function, and intestinal digestion. A total of 1,200 barrows and gilts ([Large White × Landrace] × Duroc) with average initial body weight (BW; 27.74 ± 0.28 kg) were housed in 40 pens of 30 pigs per pen (gilts and barrows in half), blocked by BW and gender, and fed five experimental diets (eight replicate pens per diet). The five experimental diets were control diet (basal diet with no FeSO4 supplementation), and the basal diet being supplemented with 150, 300, 450, or 600 mg/kg Fe as FeSO4 diets. The trial lasted for 100 d and was divided into the growing phase (27 to 60 kg of BW) for the first 50 d and the finishing phase (61 to 100 kg of BW) for the last 50 d. The basal diet was formulated with an Fe-free trace mineral premix and contained 203.36 mg/kg total dietary Fe in the growing phase and 216.71 mg/kg in the finishing phase based on ingredient contributions. And at the end of the experiment, eight pigs (four barrows and four gilts) were randomly selected from each treatment (selected one pig per pen) for digesta, blood, and intestinal samples collection. The results showed that the average daily feed intake (P = 0.025), average daily gain (P = 0.020), and BW (P = 0.019) increased linearly in the finishing phase of pigs fed with the diets containing Fe. On the other hand, supplementation with different Fe levels in the diet significantly increased serum iron and transferrin saturation concentrations (P < 0.05), goblet cell numbers of duodenal villous (P < 0.001), and MUC4 mRNA expression (P < 0.05). The apparent ileal digestibility (AID) of amino acids (AA) for pigs in the 450 and 600 mg/kg Fe groups was greater (P < 0.05) than for pigs in the control group. In conclusion, dietary supplementation with 450 to 600 mg/kg Fe improved the growth performance of pigs by changing hematological status and by enhancing intestinal goblet cell differentiation and AID of AA.
