Background Iron (Fe) is traditionally supplemented in poultry and swine diets using inorganic forms (e.g. sulfates, oxides). However, research suggests that organic sources are more beneficial due to greater bioavailability. In this paper, we present results from four studies aimed at assessing ferric citrate (CI-FER™, Akeso Biomedical Inc., Burlington, MA, USA) as a safe and effective source of Fe for broilers and piglets. Methods A total of four studies were performed in Germany following standard farming practices for each species. One study in day-old broiler chicks and one study in weaned piglets were designed as target animal safety studies where animals were randomly allocated to one of three treatment groups: a negative control group, the proposed dose group and a multifold dose group. Broilers and pigs were fed the experimental diets for 35 and 42 days, respectively. In each study, average daily feed intake, average daily weight gain and feed conversion ratio were measured, and blood samples were taken at study end for routine biochemistry and haematology. The other two studies were designed to evaluate different sources of dietary Fe for weaned piglets bred and managed under standard farm conditions. All piglets received routine Fe injections (200 mg Fe dextran, intramuscular) on day 3 of age, as well as the experimental diets for 42 days. In both studies, performance parameters were measured. In one study, Fe digestibility and serum Fe, superoxide dismutase and haptoglobin were also measured. In all studies, the general health status of the animals was monitored daily and all culls and mortality recorded. Each study followed a complete randomised block design. Results In broilers, ferric citrate was well tolerated up to 2,000 mg/kg feed (×10 the recommended inclusion rate) and no adverse effects on growth, blood parameters or mortality were observed. In piglets, ferric citrate was well tolerated up to 5,000 mg/kg feed (×10 the recommended inclusion rate) with no adverse effects on growth, blood parameters or mortality. In addition, piglets fed ferric citrate performed significantly better than animals fed the negative control diet (containing only endogenous Fe) and those fed inorganic forms of Fe. Moreover, piglets fed ferric citrate demonstrated improved Fe digestibility and improved oxidative status. Altogether, these findings show that ferric citrate is a safe and easily digestible source of dietary Fe for broilers and piglets.

AbstractThe aim of the study was to assess the gut microbiota and selected haematological and biochemical blood parameters of weaned piglets following dietary supplementation with a probiotic and vitamin C. the piglets were divided into a control group (group C) and an experimental group (group E), with 30 piglets in each group. All animals received the same feed ad libitum. The animals in the control group (group C) received feed with no added probiotic and vitamin C. the piglets in the experimental group (group E) were given a supplement containing a probiotic (Bacillus cereus 1×109 CFU/kg) in the amount of 1.5 g/piglet/day and vitamin c in the amount of 300 mg/piglet/day. The supplement was administered for 28 days. The total numbers of bacteria of the family Enterobacteriaceae and of the genus Lactobacillus were determined in faeces. The erythrocyte count, haemoglobin level, haematocrit, leukocyte count, and percentages of neutrophils and lymphocytes were determined in the blood. The biochemical analysis concerned the concentration of triacylglycerols, total cholesterol, and LDL and HDL cholesterol. In group E a significant decrease (P<0.01) in the total number of Enterobacteriaceae bacteria was observed in the faeces of the piglets, accompanied by an increase in the number of lactobacilli relative to group C. E. coli was found to predominate over other microorganisms. Salmonella choleraesuis bacteria were present in the faeces of both groups before administration of the supplement, but were not found after its use. The supplement with probiotic and vitamin C caused a significant increase in the erythrocyte, haemoglobin and haematocrit levels in the blood of the piglets and a significant decrease in the concentration of triacylglycerols, total cholesterol and LDL cholesterol.

This study aimed to test the effects of dietary Aloe vera and Symphytum officinale extracts added separately or in combination with symbiotics on the performance, nutrient utilization, serum biochemical parameters, biometrics, and intestinal histomorfometry of broilers. The experiment had a randomized block design with five treatments and six replicates of ten broilers each. Treatments were as follows: negative control and positive control (diet without and with antibiotic, respectively); 0.2% Aloe vera (AV); 0.2% Symphytum officinale (S); 0.2% functional supplement, composed of symbiotics fermented in Aloe vera and comfrey plant extracts (S+PE). At seven days of age, FI of birds fed the Aloe vera extracts diets were lower than that observed for birds consuming the diet with Symphytum officinale extract and S+PE. Broiler performance remained unaffected by treatments at others ages evaluated. At 10 to 14 days of age the lowest ADCDM ADCCP was shown in group feed NC. The highest ADCCP was observed in PC control group and in diets supplemented with Aloe vera and S+PE. Serum levels of cholesterol, triglycerides, and phosphorus were affected by addition of extracts at seven, 21, and 35 days of age. The longest duodenal villi were observed in broilers fed S+PE diets at seven days of age. Aloe vera and Symphytum officinale extracts and symbiotics can be used in broiler diets as an alternative to growth-promoting antibiotics.

ABSTRACT: This study was conducted to assess the use of propolis ethanolic extract as an alternative to performance-enhancing antibiotics for piglets. Seventy piglets weaned at 21 days of age, with initial weights of 7.3±0.4kg and final weights of 24.9±1.2kg, were randomly assigned to five diets: positive control (diet with 200ppm antibiotic); negative control (diet without growth promoter); and diets with 100, 500, and 1,000ppm of brown propolis ethanolic extract, with seven replicates of two piglets each. The duration of the experimental period was 35 days. The diets did not influence (P>0.05) daily feed intake, daily weight gain, final weight, and feed conversion of animals. The bacteriological profile of the nasal swab presented a predominance of gram-positive bacteria commonly associated with the mucous membranes in all samples. Rectal swabs did not present atypical bacterial isolates. The use of ethanolic propolis extract in diets did not alter the performance of weaned piglets, nor did it affect the bacteriological profile, fecal score, or the occurrence of diarrhea in piglets.

Abstract Background Preterm infants have immature gastrointestinal tracts and poor immunity. In this study, the effects of Lactobacillus reuteri DSM 17938 first on early feeding tolerance, growth, and second on infection prevention in preterm infants were evaluated. Methods One hundred fourteen formula-fed preterm infants with a gestational age between 30 weeks and 37 weeks, and a birth weight between 1500 and 2000 g were enrolled; 57 in the intervention and 57 in the control group:the intervention group was given a dose of 1 × 108 colony-forming units (5 drops) of L. reuteri DSM 17938 once daily, beginning with the first feeding until discharge. The control group did not receive probiotics. Early feeding tolerance (as time to full enterla feeding and number of reflux), growth, incidences of sepsis, localized infection, NEC, and adverse effects were recorded for both groups. Results The number of Daily reflux episodes (times/d) was lower (2.18 ± 0.83 vs. 3.77 ± 0.66, P < 0.01) and time to full enteral feedings (120 mL/kg/d) (9.95 ± 2.46 d vs. 13.80 ± 3.47 d, P < 0.05) was shorter in the intervention group. Average daily weight gain (14.55 ± 3.07 g/d vs. 10.12 ± 2.80 g/d), head circumference increas e(0.0760 ± 0.0157 cm/d vs. 0.0681 ± 0.0108 cm/d), and body length increase (0.1878 ± 0.0151 cm/d vs. 0.1756 ± 0.0166 cm/d) of the intervention group were higher (P < 0.01). There were no significant differences in the incidences of sepsis (4.44% vs. 8.33%), localized infection (6.67% vs. 8.33%), or NEC (2.22% vs. 10.42%) between the 2 groups (P > 0.05). The number of daily defecations (times/d) in the intervention group was higher (3.08 ± 0.33 vs. 2.29 ± 0.20, P < 0.01) and the length of hospital stay was shorter than that in the control group (20.60 ± 5.36 d vs. 23.75 ± 8.57 d, P < 0.05). No adverse effects were noted among the infants receiving L. reuteri. Conclusion L. reuteri may be an useful tool in improving early feeding tolerance in preterm infants, promoting growth, increasing the frequency of defecation, and shortening the length of hospital stay.

Objective: To study the effects of a mixture of ferulic acid and gastrodin on spontaneous activity in mice, we explored the pharmacological effects on the central nervous system. Methods: 50 healthy adult mice were randomly divided into five groups, each 10 mixture times the dose groups, respectively. The negative control group (ig same volume of saline) (ig ferulic acid 0.76mg • kg-1, gastrodin 1.06mg • kg-1), a 2-fold dose group (ig ferulic acid 1.52mg • kg-1, gastrodin 2.12mg • kg-1), 4-fold dose group (ig ferulic acid 3.04mg • kg-1, gastrodin 4.24mg • kg-1), 8-fold dose group (ig ferulic acid 6.08mg • kg-1, gastrodin 8.48mg • kg-1). We measured the spontaneous activity in mice before and after the administration of 10min, 20min, 30min, 40min, 50min, 60min, 80min, 100min, 120min, 180min, 240min, 360min. Results: Compared with the negative control group, there was a significant excitatory effect in 1-fold dose of spontaneous activity in mice in 60min, 80min, 100min (P<0.05, P<0.01); while 4-fold and 8-fold dose in 80min (P<0.05, P<0.01). Conclusions: There was an exciting effect of a mixture of ferulic acid and gastrodin in a certain dose range, but not in a dose-dependent manner.

ABSTRACT The objective of this study was to evaluate the use of an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in the feed of swine in growing and finishing phases, by assessing their performance (daily weight gain, daily feed intake, and feed conversion), dry matter, crude protein, and crude energy apparent digestibility, and the feed costs. Eighty pigs-castrated males, and females-of approximately 63 days of age and initial weight of 20.18±1.98 kg were distributed in a 5×2 factorial arrangement (diet × sex), in a randomized block design, with eight replications. The treatments used were: positive control diet consisted of 3,300 kcal/kg in the growth-I phase, and 3,250 kcal/kg in the growth-II and finishing phases; negative control diet with energy reduction of 85 kcal/kg of metabolizable energy (ME) (NC85); NC85 diet with addition of enzyme complex (EC85); negative control diet with energy reduction of 100 kcal/kg ME (NC100); NC100 diet with addition of enzyme complex (EC100). The addition of the enzyme complex to the diet with energy reduction of 100 kcal/kg ME increased the digestible protein content of the diet for the swine in the growth-II phase. The addition of the enzyme complex to the diet with energy reduction of 85 and 100 kcal/kg ME increased the digestible energy content of the diets for the swine in the finishing phase. The use of enzyme complex in diets with reduction of 85 kcal/kg ME for male swine in growing and finishing phases is recommended for improving feed conversion and economic efficiency during the growth-I phase. The use of enzyme complex is not justified for female swine.

The purpose of the research is to study the effect of extractive substances from a complex of herbs (R. Carthamoides, S. Coronate, F. ulmaria )on individual indicators of the metabolism of laboratory mice, pregnant sows and piglets obtained from them. A phytoextract containing ecdysteroids and flavonoids was orally administered to white mice ( three experimental and one control group of 15 mice) in doses of 0.1; 0.2 and 0.3 ml during 14 days that provided an increase in the average daily weight gain by 20.8-48.5% (P <0.05) in comparison with the control. The introduction into the diet of pregnant sows (three experimental groups and one control group of 10 sows) of an additive containing a phytoextract once a day at doses 3, 5 and 10 grams per head within 30 days before farrowing did not cause deviations from the norm of the studied biochemical blood parameters (total protein, albumin, cholesterol, calcium, phosphorus, magnesium, urea, creatinine, ALT, AST). The blood parameters of sows in the experimental groups characterizing the metabolic status of the organism were within the reference limits: total protein 60.7±0.4-62.0±0.3 g/l; albumin 44.2±0.4-52.7±1.8 g/l; cholesterol 2.14±0.04-2.90±0.01 mmol/l; Ca 2.50±0.05-2.62±0.01 mmol/l; P 2.91±0.0-3.16±0.04 mmol/l; Mg 0.92±0.02-1.28±0.01 mmol/l; AST 27.6±2.4-29.3±0.5 units; ALT 23.7±1.1-26.9±1.3 units; urea 4.8±0.2-7.9±0.5 mmol/l; creatinine 101.2±3.5-110.0±2.1 mkmol/l. The number of newborn piglets obtained from sows in the experimental groups exceeded the indicator in the control (127 heads) by 6.2%, of which live by 10.6% (in the control, 113 heads), the number transferred for weaning by 11.2% (in control 107 heads), gross growth by 9.8% (control 887 kg). The rest of the studied parameters of piglets (average weight of a piglet during transfer, average daily growth, survivability) did not differ significantly from the control (P> 0.05). It has been established that the phytoextract had an anabolic effect on white mice, did not cause a negative effect on the studied biochemical parameters of metabolism in pregnant sows, and contributed to an increase in the number of live newborns in comparison with the control.

AbstractThe aim of this study was to investigate the effect of hempseed cake on production traits, metabolic profile and antioxidant status of lambs. The research was conducted on 20 Merinolandschaf lambs of similar live body weight (24.03 kg ± 2.22 and 24.06 ± 1.84 kg in control and experimental group, respectively). The experiment started after the weaning of lambs at their average age of 70 days. Lambs were divided by gender (50% male: 50% female) and then allocated in two groups. The research lasted for 30 days during the fattening period. Lambs in the control group were fed with feed mixtures, where main protein source was soybean meal and extruded soybean (SB), while lambs in the experimental group were fed feed mixtures in which soybean was replaced by hempseed cake (HSC) at 12% of dry matter. Higher values of daily weight gain (P<0.05) compared to SB lambs were observed from the 15th to 30th day. HSC lambs showed no significant differences in hematology and biochemical blood parameters, except for lower (P<0.001) urea concentrations on days 15th and 30th, as well as higher (P<0.05) Mg concentrations in serum on the 30th day. Hempseed cake in lambs′ diets did not influence (P>0.05) activity of the enzymes, like AST, ALT, ALP, GGT and CK, as well as SOD and GPx enzymes, thus not affecting the antioxidant status of lambs′ blood. Concentrations of DHA and n-3 fatty acids were higher (P<0.05) in HSC group than in SB group. The present study confirmed that the inclusion of HSC as soybean replacement up to 12% in the lambs’ diet is justified when considering production traits, metabolic profile and antioxidant status of Merinolandschaf lambs.

Abstract Background: The olive extract contains compounds with antioxidant and anti-inflammatory properties. This study was designed to investigate whether olive cake extract, enriched with maslinic acid and hydroxytyrosol, alleviates the lipopolysaccharides (LPS)-induced oxidative stress, inflammation and intestinal villus damage in piglets.Methods: Thirty weaned piglets (6.9±0.9 kg) were assigned to five groups using a randomized complete block design. Piglets were fed a basal diet before intraperitoneal (i.p.) injection of physiological saline (C); fed a basal diet alone (CL) or fed a basal diet plus olive extract (OL), antibiotics (AL), or olive extract and antibiotics (OAL) before i.p. injection of LPS. The feeding lasted for 2 weeks. Piglets were euthanized 4h after LPS injection. Systemic anti-oxidant and inflammation levels were measured and villus morphology in the intestine was examined.Results: Compared with those in the C group, piglets in the CL group had significantly lower GSH-Px, SOD, ALB levels and higher MDA, NO, LDH, ALT and AST levels in the serum (P<0.05). Compared with the CL group, piglets in OL, AL, and OAL groups had significantly higher serum GSH-Px, SOD and ALB levels and lower MDA, NO, LDH, ALT and AST levels (P<0.05). LPS administration significantly increased the serum concentration of TNF-α, IL-6, DAO and D-xylose in the CL group compared with the control group (P<0.05). Piglets in OL, AL, and OAL groups had significantly lower serum TNF-α, IL-6, DAO and D-xylose levels and higher IL-10 level (P<0.05). In the duodenum and ileum of piglets, LPS challenge led to significantly lower villus height (VH), higher crypt depth (CD) and lower VH/CD compared with the control group (P<0.05), whereas, OL, AL, and OAL groups had significantly lower CD and higher VH/CD compared with the CL group (P<0.05). Dietary inclusion of olive extract increased the relative abundance of intestinal Lactobacillus and Clostridium at genus level.Conclusion: Dietary supplementation with olive extract maslinic acid and hydroxytyrosol improved anti-oxidative and anti-inflammatory capacity, intestinal structure morphology, and increased the abundance of beneficial intestinal bacteria in weaned piglets challenged by LPS.

Abstract Probiotics are being considered as an alternative means to reduce pathogen infection and improve animal health especially around the time of weaning. The objective of our study was to evaluate the effects of the use of a probiotic in diets for piglets on their performance and intestinal integrity during nursery phase. Thirty-six piglets (18 barrows and 18 females), weaned at 24 days of age were distributed in a randomized block design, with six repetitions per treatment (with or without addition of 50g/ton of the probiotic Bacillus subtilis DSM 32315, GutCare®, Evonik Industries) and each repetition with three pigs per experimental unit. During the experimental period, performance parameters evaluated were body weight (BW), daily feed intake (ADFI), feed conversion, average daily weight gain (ADG) and the intestinal integrity assessed via galactose absorption capacity. The performance data were submitted to the PDIFF option of the SAS and compared using the Tukey test. During phase 1 (24 to 31 days of age) the use of the probiotic tended (P = 0.07) to improve ADG (+76 g/ d) in comparison to control. As for phase 2 (32 to 39 days of age), 3 (40 to 53 days of age) and 4 (54 to 70 days of age) the use of the probiotic increased the ADFI (+118, +66 and +162 g/ d, respectively; P &lt; 0.05) and ADG (+5 and +8%, respectively for phase 2 and 3; P &lt; 0.05) compared to control. The use of the probiotic improved (P = 0.05) nursery end BW (+1.3 kg) and overall ADFI (+8%; P = 0.046). The intestinal integrity was not affected by treatments (P &gt; 0.10) at any stage. In conclusion, the use of the probiotic Bacillus subtilis DSM 32315 in diets for weaned piglets can be used as a viable formulation strategy to improve performance and the intestinal health of the animals during nursery phase.
