Abstract Selenium (Se) is an essential trace element for animals and exists in nature in both inorganic and organic forms. Although organic Se is more bioavailable than inorganic Se, there are inconsistent reports on the effect of organic Se on the reproductive performance of sows. This study was conducted to investigate the effect of maternal organic Se (2-hydroxy-4-methylselenobutanoic [HMSeBA]) supplementation on reproductive performance and antioxidant capacity of sows, and the long-term effect on the growth performance and antioxidant capacity of their offspring with or without lipopolysaccharide (LPS) challenge. The experimental design used in this study was a completely randomized design; 45 Landrace × Yorkshire sows were randomly allocated to receive one of the following three diets during gestation: control diet (Control, basal diet, n = 15), sodium selenite (Na2SeO3)-supplemented diet (Na2SeO3, basal diet + 0.3 mg Se/kg Na2SeO3, n = 15), and HMSeBA-supplemented diet (HMSeBA, basal diet + 0.3 mg Se/kg HMSeBA, n = 15). On day 21 of age, male offspring from each group were injected with LPS or saline (n = 6). As compared with the control group, maternal HMSeBA supplementation increased the number of total born piglets, while decreased birth weight (P < 0.05). In the first week of lactation, maternal HMSeBA supplementation increased litter weight gain compared with the Na2SeO3 group (P < 0.05) and increased the average daily gain of piglets compared with the control group and Na2SeO3 group (P < 0.05). Meanwhile, maternal HMSeBA supplementation decreased piglet birth interval as compared with the control group and Na2SeO3 group (P < 0.05). Besides, plasma glutathione peroxidase (GSH-Px) activity was higher in the HMSeBA group on farrowing 0 min and 90 min, while malondialdehyde (MDA) concentration was lower on farrowing 0, 90, and 135 min than those in the control group (P < 0.05). In addition, maternal HMSeBA supplementation increased the concentration of selenoprotein P (SELENOP) in colostrum compared with the control group (P < 0.05). Further study revealed that the LPS-challenged HMSeBA group had higher GSH-Px and total antioxidant capacity and lower MDA in weaning piglets compared with the LPS-challenged control group (P < 0.05). Taken together, maternal HMSeBA supplementation increased the number of total born piglets, shortened the duration of farrowing, improved the antioxidant capacities of sows and their offspring, and improved the growth performance of suckling pigs at the first week of lactation. Thus, HMSeBA supplementation during gestation has the potentiality to produce more kilogram of meat.

EGF has been shown to stimulate the growth of animals. In this study, the content of EGF in chicken embryos (gallus EGF, gEGF) aged from 1 to 20 days of incubation were determined by ELISA kit, and the 5-day-old chicken embryos with the highest content of 5593 pg/g were selected to make gEGF crude extracts. A total of 1500 1-day-old Xianju chickens were randomly divided into five groups with six replicates of 50 chickens each. The control group was fed a basal diet, and other treatment diets were supplemented with 4, 8, 16 and 32 ng/kg gEGF crude extract, respectively. The experiment lasted for 30 days. Chicks were harvested at the end of the experiment, and liver, spleen, thymus, bursa and serum samples were collected. Results showed that average daily gain (ADG) and average daily feed intake (ADFI) of 16 ng/kg group were higher than those in the control group (p < 0.05). The serum uric acid (UA) of the 16 ng/kg group was reduced (p < 0.01), and the serum alkaline phosphatase (AKP) of the 16 ng/kg group increased (p < 0.01). The gEGF extract also increased chick’s antioxidant capacity, decreased malondialdehyde (MDA) and increased catalase (CAT) in the liver and serum of 16 ng/kg groups in compared to the control group (p < 0.01). Furthermore, immunity was improved by the addition of gEGF to broiler diets. The serum immunoglobin A (IgA) content of 8 and 16 ng/kg groups and the serum immunoglobin M (IgM) content of 4 and 8 ng/kg groups were increased (p < 0.05) compared to the control group. The bursa index of each experimental group was higher than the control group (p < 0.01). These findings demonstrate that the crude extract of gEGF prepared in this experiment could improve the growth performance, antioxidant capacity and immunity of broilers.

Abstract Porcine small intestine submucosa (SIS) biologic patch has been used in inguinal hernia repair. However, there are little data available to assess the long-term effect after repair. This study aimed to explore the long-term effect of SIS patch in open inguinal hernia repair. Sevent-six patients with unilateral inguinal hernia were treated with Lichtenstein tension-free hernia repair using SIS patch (Beijing Datsing Bio-Tech Co., Ltd.) and Surgisis patch (COOK, USA) in Tianjin Union Medical Center and China-Japan Friendship Hospital. In the trial, the long-term efficacy of the treatment group and the control group were compared. A total of 66 patients in both groups received long-term follow-up (&gt; 5 years) after surgery, with a follow-up rate of 86.8%. During the follow-up period, there was one case of recurrence, one case of chronic pain in the control group. There was no statistically significant difference (P &gt; 0.05) in terms of recurrence, chronic pain, foreign body sensation and infection between the two groups of patients. After long-term observations, it has been found that the porcine small intestinal submucosa (SIS) biological patch is safe and effective for inguinal hernia Lichtenstein repair, and has a low recurrence rate and complication rate.

Abstract Objective The study objective was to evaluate the long-term effect of radiosynoviorthesis (RSO) on the progression of radiological and nuclear-medical osteoarthritic features of hip and ankle joint in patients with osteoarthritis and rheumatoid arthritis. Patients and Methods The study included 89 hip joints of 81 patients, of which 48 had osteoarthritis (OA) and 33 had rheumatoid arthritis (RA). In terms of ankle joints, 64 patients were included of which 43 suffered from OA and 21 from RA. The mean follow-up time was 9.2 years for OA and 8.9 years for RA patients. Patients with RA were the active control group. Structural alterations of the hip joints were evaluated following Kellgren-Lawrence score and of ankle joint following Takakura score for both disease entities. For the evaluation of synovitis 2-phase bone scintigraphy was performed. Results RSO could prevent radiologic status deterioration among 70.6 % of hip osteoarthritic patients and 73.7 % among the hip RA patients. No structural progression was observed in 79.1 % of the treated ankle joints in patients with OA and in 85.7 % of the ankle joints in patients with RA.The scintigraphic response rate for the hip joints of OA patients was 68.6 %, 76.3 % for hip joints of RA patients, 83.1 %, ankle joints of OA patients, and 90.4 % ankle joints of RA patients.The radiographic and scintigraphic RSO response rates were not significantly higher for both joints in RA than OA patients. Conclusion RSO can be a good alternative in the treatment of synovitis and prevention of deterioration of inflammatory and radiographic features even in patients suffering from osteoarthritis and rheumatoid arthritis. RSO may have also a long-term effect to stop or delay progression of both diseases.

Background and Aim: Weaning pigs normally suffer from many stressors which have impaired growth performance and immunity. Hydrolyzed yeast has been proposed as an alternative feed additive. The aim of this study was to investigate the effects of various levels of hydrolyzed yeast (HY) supplementation in the feed of weaning pigs on growth performance, diarrhea incidence, immunity, antioxidant capacity, and microbial populations. Materials and Methods: A total of 144 crossbred weaning pigs (Duroc × Landrace × Large White) with a mean body weight (BW) of 7.46 kg were randomly assigned to one of four treatments during a 5-week feeding trial. Treatments consisted of a basal diet without HY inclusion (control), or the basal diet supplemented with HY at 0.5, 1.0, and 1.5 g/kg of diet, respectively. Results: Piglets fed with 1.0 or 1.5 g/kg HY presented significantly increased BW (p=0.009) and decreased incidence of diarrhea (p=0.001). The final BW (p=0.012), average daily gain (p=0.094), and average daily feed intake (p=0.091) showed a linear improvement with the level of HY inclusion. However, the gain-to-feed ratio was unaffected by dietary treatments. Linear responses to the HY supplementation levels were also observed for blood urea nitrogen (p=0.030), total protein (p=0.017), lymphocyte percentage (p=0.064), catalase activity (p=0.089), malondialdehyde (MDA) level (p=0.001), Salmonella spp. (p=0.024), Escherichia coli (p=0.021), and Lactobacillus spp. (p=0.048). Dietary inclusion of HY at 1.0 and 1.5 g/kg resulted in increased immunoglobulin A and G secretions (p=0.042 and p=0.022, respectively) and decreased MDA concentration (p<0.01) and Salmonella spp. (p=0.026) and E. coli (p=0.050). Conclusion: It was concluded that HY inclusion at 1.0 and 1.5 g/kg in the diet of weaning pigs improve BW, immunoglobulin secretion, and antioxidant enzyme activity, whereas it lowers diarrhea occurrence, lipid peroxidation, and pathogenic bacteria in weaning pigs.

Abstract Background Garlic and its constituents exhibit activities on modifying rumen fermentation and improving growth performance. As a by-product of garlic processing, garlic skin contains similar bioactive components as garlic bulb. However, studies in ruminants using garlic skin are scarce. This study was conducted to investigate the effects of garlic skin supplementation on rumen fermentation characterizes, growth performance, ruminal microbes and metabolites in ruminants. Twelve Hu lambs were randomly assigned into one of two treatments: basal diet (CON) or basal diet supplemented with 80 g/kg DM of gallic skin (GAS). The experiment lasted for10 weeks, with the first 2 weeks for adaptation. Results The results revealed that the average daily gain and volatile fatty acid concentration were higher (P < 0.05) in lambs fed GAS than that in the control group. Garlic skin supplementation did not significantly (P > 0.10) affect the α-diversity indices. Increased (P < 0.05) abundances of Prevotella, Bulleidia, Howardella, Methanosphaera but a decreased (P < 0.05) abundance of Fretibacterium were observed in GAS-fed lambs. In addition, the garlic skin supplementation favorably regulated (P < 0.05) pyrimidine metabolism, purine metabolism, vitamin B6 and B1 metabolism. Moreover, high correlations were observed between fluctuant rumen microbiota and metabolites. Conclusions Supplementation of garlic skin improved the growth performance of sheep by modifying rumen fermentation through inducing shifts in the rumen microbiome and metabolome.

Abstract Glucan has been studied as a potential alternative to antibiotics for animals in recent years. The aim of this study was to evaluate the effect of dietary glucan on growth performance and gut health of weaning piglets, which is a water-soluble extracellular ꞵ-glucan produced by Agrobacterium sp. ZX09. A total of 108 weaned piglets (21 d of age; 6.05 ± 0.36 kg) were randomly assigned (6 pens/diet; 18 piglets/pen) to 3 dietary treatments consisting of a basal diet (control group) or the basal diet supplemented with 20 ppm olaquindox or 200 ppm glucan for 14 days, respectively. The results showed that piglets fed with glucan had greater (P &lt; 0.05) body weight and average daily gain than piglets in control group. Piglets fed with glucan or antibiotic had greater villus height to crypt depth ratio on duodenum compared with control group (P &lt; 0.05). The mRNA expression of Claudin-1 on duodenum or ileum was higher (P &lt; 0.05) in glucan group than that on the other groups. The mRNA expression of TLR4, MYD88 and NFκB on jejunum were lower (P &lt; 0.05) in glucan or antibiotic group than those in control group. Dietary supplementation with glucan tended to increase the IL-10 and SIgA concentration on ileum (0.05 &lt; P &lt; 0.1). Dietary supplementation with glucan tended to increase the total antioxidant capacity on jejunum (P = 0.093). In conclusion, 200 ppm glucan or 20 ppm olaquindox can improve the growth performance of weaning piglets. The glucan may can accelerate the growth of weaned piglets by improving gut health. This research will provide guidance for the olaquindox alternative on growing piglets.

Heat stress has a profound effect on poultry health and productivity. The present study evaluated whether feeding betaine could ameliorate long-term heat stress-induced impairment of productive performance in indigenous yellow-feathered broilers. A total of 240 five-week-old male broilers were randomly allocated to five treatments with six replicates of eight broilers each. The five treatments included a thermoneutral zone control group (TN, fed basal diet), a heat stress control group (HS, fed basal diet), and an HS control group supplemented 500, 1000, 2000 mg/kg betaine, respectively. The TN group was raised at 26 ± 1 °C during the whole study, HS groups exposed to 32 ± 1 °C for 8 h/day from 9:00 am to 17:00 pm. The results showed that heat stress decreased the body weight gain (BWG) and feed intake of broilers during 1–5, 6–10, and 1–10 weeks (p < 0.05). Dietary betaine tended to improve the BWG and feed intake of broilers under 5 weeks of heat stress (linear, p < 0.10), and betaine supplementation linearly increased the BWG and feed intake during 6–10 and 1–10 weeks (p < 0.05). Additionally, nitrogen retention was reduced by 5 weeks and 10 weeks of heat stress (p < 0.05), whereas dietary betaine could improve nitrogen retention in heat stressed broilers after both 5 and 10 weeks of heat stress (linear, p < 0.05). Moreover, this study observed that the trypsin activity of jejunum was decreased by 5 weeks of heat stress (p < 0.05), whereas betaine supplementation had quadratic effects on trypsin activity of jejunum in heat stressed broilers (p < 0.05). Furthermore, 10 weeks of heat stress induced a reduction of villus height of the duodenum and jejunum (p < 0.05), and decreased the villus height to crypt depth ratio of the jejunum (p < 0.05). Supplementation with betaine ameliorated the adverse effects of heat stress on these parameters (p < 0.05). Compared with the TN group, 10 weeks of heat stress reduced carcass and breast yield (p < 0.05) and betaine supplementation improved carcass and breast yield of heat stressed broilers (linear, p < 0.05). In conclusion, dietary supplementation of betaine could reduce the detrimental effects of long-term heat stress on growth performance, digestive function, and carcass traits in indigenous yellow-feathered broilers.

Ninety young Merino ewes, depastured on Mitchell (Astrebla spp.) grass pastures in North West Queensland, were used in a hormonal growth promotant implantation study. The ewes were given 1 implant of Compudose, Ralgro, Revalor or Synovex-H, either at lamb marking (mid-dry season) or the start of the following summer wet season, which was ~180 days post-marking. The hormonal growth promotant implanted groups had greater (P<0.05) liveweights than the control group early in the trial (days 22 and 57) and also from the end of the period of activity of the wet season implant (day 277) until the middle of the dry season (day 412). Dry season (at lamb marking) implantation did not improve average daily gain. From the end of the wet season onwards, ewes with a wet season implant were heavier (P<0.05) than those ewes implanted at lamb marking. This liveweight advantage had diminished by the start of the autumn mating. Hormonal growth promotant implantation had a favourable (P<0.05) effect on growth rate, but adversely affected reproduction in the ewes, regardless of time of implantation. Implantation with Compudose or Synovex-H significantly (P<0.001) reduced the demonstration of oestrus, while Revalor or Synovex-H reduced pregnancy rates by up to 100%. Despite Ralgro reducing these variables by up to 25%, its effect was not significant. All ewes that were diagnosed as pregnant at 140 days later produced lambs. It was concluded from this study that hormonal growth promotant implantation at lamb marking provides no later-life advantage, while wet season implantation provides a growth or liveweight advantage to young Merino ewes and this persists for a long period after implantation. Despite the lack of an effect of Ralgro on oestrus and pregnancy results, however, implantation of young breeding ewes of any age should not be carried out, due to the long term and negative effects on reproductive performance. Wet season implantation may be best used for animals intended for slaughter.

To investigate the effect of lipopolysaccharides (LPS) on the growth performance, nitrogen metabolism and immunity in preruminant calves, forty Chinese Holstein male calves were randomly divided into two groups and injected intraperitoneally with 2.5 mg/kg BW of sterile saline or E. coli LPS (Escherichia coli O55:b55) on day 24, 26, and 28. The LPS challenge decreased average daily gain and feed conversion efficiency compared with control group (p less than0.05). The urinary concentration of nitrogen (pless than0.05) increased, whereas the nitrogen retention decreased (pless than0.05) after LPS-challenge. Injection of LPS increased body temperature, serum concentration of IL-1, TNF-a, IL-2 and IgG of calves. In conclusion, LPS-challenge activated immune responses, decreased utilization efficiency of nitrogen, and negatively impacted growth performance of preruminant calves.

Abstract Heme is an efficient dietary iron supplement applied in humans and animals to prevent iron deficiency anemia (IDA). We have recently reported that the use of bovine hemoglobin as a dietary source of heme iron efficiently counteracts the development of IDA in young piglets, which is the common problem in pig industry. Here, we used maternal Polish Large White and terminal sire breed (L990) pigs differing in traits for meat production to evaluate the long-term effect of split supplementation with intramuscularly administered small amount of iron dextran and orally given hemoglobin on hematological indices, iron status, growth performance, slaughter traits, and meat quality at the end of fattening. Results of our study show that in pigs of both breeds split supplementation was effective in maintaining physiological values of RBC and blood plasma iron parameters as well as growth performance, carcass parameters, and meat quality traits. Our results prove the effectiveness of split iron supplementation of piglets in a far-reach perspective.
