Abstract The effect of feed mixture supplementation with MgCl2 on alimentary tract microflora, haematological markers, and selected parameters of reproductive performance of sows was investigated. The animals were divided into control group (K) and two experimental groups (E1 and E2). The sows from the experimental groups were receiving 1 g of MgCl2 6H20/100 kg b.w./day, which constituted 120 mg of pure magnesium, administered in a small portion of a feed mixture. The sows from group E1 were receiving MgCl2 every day for 30 d, whereas sows from group E2 for 60 d. A significant decrease in the count of E. coli, Providencia sp., and Proteus sp. was noted in faeces of the swine of both experimental groups. The study has also demonstrated a reduced number of lymphocytes and an increased number of granulocytes in blood of the sows receiving MgCl2. Feeding of pregnant sows with the addition of magnesium salt decreased the mortality rate of newborn piglets, increased the survival rate of piglets until 21 d of their life, and increased body weight values of litters originating from experimental sows, compared to the litters of control sows.

The study was conducted to determine the effects of vitamin E on reproductive performance in mice treated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The 75 female and 40 male mice were randomly assigned into five groups. The levels of both TCDD and vitamin E given by gavage were 0 and 0 (Control group), 100 and 0 (experimental group I), 100 and 20 (experimental group II), 100 and 100 (experimental group III), and 100 ng/kg/day and 500 mg/kg/day (experimental group IV), respectively. Males and females were mixed to mate at the ratio of 1:2 after 4-week experiment. The gavage treatments were continued until the end of gestation in female mice after mating. The results showed that the litter number, survival rate, and body weight at birth of offspring in experimental group I had significantly decreased, and the females’ pregnancy rate and pup sex ratio in experimental group I had the decreasing tendencies when compared with the control group. The litter number in experimental group III, survival rate in experimental group II and III, body weight at birth in experimental group III and IV exhibited significant increase compared with experimental group I. The female pregnancy rate in both experimental group III and IV recovered to 100%, but there were no significant differences when compared with experimental group I. The pups’ sex ratio had a gradually increasing tendency with increase of vitamin E level, but there was no significant difference among experimental group I–IV. The results suggest that TCDD could induce reproductive toxicity in mice, whereas vitamin E alleviated adverse effects on reproductive performance in mice caused by TCDD.

Multiple organ dysfunction syndrome (MODS) is a key factor that leads to death in elderly patients with sepsis. Therefore, early prevention and treatment of gastrointestinal dysfunction (GIDF) in elderly patients with sepsis is an important measure to prevent MODS occurrence. This research explores the correlation between intestinal microflora and GIDF in elderly patients with sepsis and provides ideas for the prevention and treatment of GIDF in elderly patients with sepsis. In this study, 152 patients with sepsis (122 patients with sepsis and GIDF) treated in the Third Affiliated Hospital of Yunnan University of Chinese Medicine from January to September 2019 were selected as the sepsis group and 100 elderly who had normal physical examination results were selected as the control group. The common intestinal microflora of the two groups was compared. Patients with sepsis and GIDF were treated as the GIDF group and the other patients with sepsis were treated as the non-GIDF group. The common intestinal microflora, gastrointestinal indicators, serum inflammatory factors, and immune function indices were compared between the two groups. Correlation analysis of the observed indices with statistical significance was carried out. The results showed 152 patients with sepsis and 122 patients with sepsis and GIDF; thus, the incidence of sepsis with GIDF was 80.26%. The total average score of sepsis with GIDF was 3.61±0.09. There was no statistically significant difference in GIDF scores of patients ages 65–75 and > 75 years old. The number of Bifidobacterium and Lactobacillus in elderly patients with sepsis was lower and the number of Escherichia coli was higher than in the control group. In elderly patients with sepsis, the number of Bifidobacterium and Lactobacillus in the GIDF group was lower and the number of E. coli was higher than in the non-GIDF group. White blood cell (WBC) count, procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), gastrin (GAS), and diamine oxidase (DAO) in GIDF patients were higher and motilin (MOT), CIT (CIT), CD4+, and CD8+ were lower than in the non-GIDF group. WBC count, PCT, CRP, TNF-α, GAS, and DAO were negatively correlated with the number of Bifidobacterium and Lactobacillus but positively correlated with E. coli. MOT, CIT, CD4+, and CD8+ were positively correlated with the number of Bifidobacterium and Lactobacillus but negatively correlated with E. coli. There was a negative correlation between Bifidobacterium and Lactobacillus and GIDF score and a positive correlation between E. coli and GIDF score. Therefore, the change in the intestinal microflora in elderly patients with sepsis is related to GIDF.

AbstractThe aim of this experiment was to examine the possibility of replacing part of soybean meal in the diets of sows, their piglets and fatteners with two varieties of high- or low-tannin faba bean seed. Twenty-four sows were allocated to 3 groups, 8 animals in each. Control group (C) received standard feed mixture containing soybean meal as the main protein source. Next groups received standard feed mixture in which part of soybean meal was replaced by high-tannin variety Bobas (group HT) or low-tannin variety Kasztelan (group LT). Faba bean was added to diets at the level of 12 and 14% for pregnant and lactating sows, 6% for piglets, and 12 and 16% for fatteners (grower and finisher, respectively). Diets for half piglets and fatteners were supplemented with the enzyme Ronozyme VP. Apparent digestibility of nutrients was evaluated in a parallel experiment, using the same feeds on 18 barrows weighing about 40 kg (grower) and 80 kg (finisher). There was almost no difference in sow reproductive rates, litter weight and body weight of piglets on the first day of life were similar. Until 35 days of age piglets receiving faba bean grew faster than control ones. Control piglets grew fastest from 35 to 84 days of age, but differences were not significant. Enzyme supplement had a positive effect on body weight only from 56 to 84 days of piglet life. Digestibility of nutrients was lower in pigs fed with faba beans, especially in the grower period. Faba bean HT had lower nutrient digestibility in both periods of fattening. Almost all carcass traits were better in control pigs than in those fed with bean variety Bobas. Meat of these pigs had also the lowest content of unsaturated fatty acids and highest atherogenic indices. In sensory evaluation this meat had also the worst smell and taste. It can be stated that faba bean seeds, in moderate amounts, can partially replace soybean meal in feed for pigs, but some lowering of body weight gain and meat quality is possible especially when high-tannin varieties are used.

This study aimed to evaluate the effects of nano mineral-supplemented diet on sow productivity. The data were estimated by several parameters consisting of piglet live ratio at newborn stage and weaning stage, piglet weight at newborn stage and weaning stage, metal content in piglet livers. The results showed that live ratio of newborn piglets in group III was highest (93.44 ± 2.83%) comparing with other groups. However, there was no significant difference of live ratio in piglets at weaning stage between nano mineral-supplemented groups with control. The birth weight of piglets in nano mineral-supplemented groups was similar to control group. The birth weight of piglets in nano mineral-supplemented groups was ranged from 1,361.61 ± 47.37 grams (group II) to 1,410.48 ± 44.28 grams (group I). However, the average weight of weaned pigs in groups III and IV was higher than other groups (6,772.92 ± 105.47 grams and 6,818.87 ± 89.59 grams). Moreover, the amount of Fe, Cu, Zn, Mn in piglet liver from nano mineral-supplemented groups have been found to be lower than those in control group. These results revealed that the supplement of nano minerals for sows promoted the reproductive performance of sows and reduced mineral content in the liver of piglets.

Abstract Mongrel dogs were treated intravenously with either 1000 units of beef-lung heparin per kilogram of body weight or with isotonic saline, before intravenous administration of E. coli endotoxin. We found significant differences in circulating norepinephrine concentrations between a heparin-pretreatment group (1.89 +/- 0.39 microgram/liter) and the control group (9.83 +/- 4.64 microgram/liter), but none with respect to epinephrine. Systolic blood pressures at 360 min were also significantly (P less than 0.05) different, 148 +/- 6 mmHg as compared with 118 +/- 13.4 mmHg. Evidently heparin pretreatment can decrease circulating norepinephrine concentrations in the endotoxic state and changes in circulating catecholamine concentrations can affect physiological variables.

The aim of this study was to determine the effect of diet supplementation with propolis and/or bee pollen on the performance indicators of broilers. This experimental study was conducted on 200 Ross 308 broilers equally distributed by sex and divided into five groups. Throughout the whole study the control group of chickens was fed feed mixture. Feed mixture fed to the experimental groups of chickens contained additives (propolis and/or bee pollen, each supplement separately or in combination in a certain proportion). The average values of broilers body weight were significantly higher on 7th (p=0.001), 14th, 21st, 28th, 35th (p<0.001) and 42nd (p=0.002) day of feeding in the experimental groups of broilers compared to the control group. The average values of broilers weight gain were significantly higher on 1st (p<0.001), 2nd (p=0.002), 3rd (p<0.001), 4th (p=0.029) and 5th (p=0.009) week of feeding in the experimental groups of broilers compared to the control group. This study has undoubtedly shown that propolis and bee pollen have significant positive effect on performance indicators of broilers.

Gnotobiotic growing rats harbouring either a whole human faecal flora or single human strains ofEscherichia coli(EM0) orBacteroides vulgatus(BV8H1) were fed for 7 weeks on semi-synthetic diets in which the protein source was either soya-bean meal (SM) or rape-seed meal (RM). For each bacterial status the RM-diet group was compared with the control group fed on the SM diet. The association of human faecal flora with the RM diet was responsible for reduced feed intake and reduced weight gain, an enlargement of the liver and thyroid and a decrease in both thyroxine and triiodothyronine plasma levels. The association of theB. vulgatusBV8H1 strain with the RM diet reproduced all these effects, except that triiodothyronine plasma levels were not significantly modified. Rats inoculated with theE. coliEM0 strain and fed on the RM diet exhibited a goitre and lowered thyroxine and triiodothyronine plasma levels. These results show that the human intestinal microflora may be involved in glucosinolate metabolism when cruciferous vegetables are consumed by man. The specificity of the symptoms observed according to the rat bacterial status supports the hypothesis that bacteria yield specific toxic glucosinolate derivatives according to their enzymic potential.

Escherichia coli is the most important etiologic agent implied in neonatal diarrhea in swine; colibacillosis is the disease with highest impact in production of swine. The demands of consumers for meat without chemical residues and the ban on the use of antibiotics and chemotherapics in production of swine compelled to find alternative therapeutic and preventive treatments. Aims: to assess homeopathic treatment as preventive against colibacillosis in swine. Methods: the study was conducted in a farm in Mato Grosso, Brazil; stools of 4 piglets with diarrhea were collected to establish the presence of E. coli; concomitantly it was performed a clinical exam to identify the symptoms leading to the choice of a homeopathy remedy. Newborn piglets were divided into 4 groups (n= 11 or 12): 1) control, subjected to antibiotic treatment against diarrhea; 2) homeopathic treatment, performed with Phosphorus 30cH according to the symptoms collected; 3) biotherapic treatment, performed with Escherichia coli 30cH prepared from the locally obtained bacteria; 4) homeopathic + biotherapics treatment. Results: all 3 groups treated with homeopathy/isotherapy presented a significant reduction of diarrhea compared to the control group (p=0.02); the group treated with Phosphorus 30cH + Escherichia coli 30cH presented the highest weight gain which was significant by comparison to all other groups (p=0.001). Conclusion: homeopathic and biotherapics treatment were more effective than antibiotics in the control of diarrhea in newborn piglets; combination of homeopathic and isopathic treatment resulted in the highest weight gain. These results suggest that homeopathy and isopathy are effective alternatives for the treatment of diarrhea by E. coli in newborn swine.

<p>The aim of the paper was to compare the effect of prebiotics (inulin and/or mannan-oligosaccharides, MOS) and bee products (bee pollen and/or propolis) on productive and reproductive performance of rabbit does. Seventy nulliparous V-line female rabbits were distributed among 7 groups. The groups were fed the same diet and received no supplements (control group), natural molecules (bee pollen and/or propolis) at 200 mg/kg body weight (BW) or prebiotics (inulin and/or MOS) at 35 mg/kg BW. Productive, reproductive, biochemical and haematological traits were investigated. Bee pollen with propolis significantly increased body weight gain of does 1 wk after mating (3.53%), decreased feed intake (4.49%) and caused larger litter size (39.4%), heavier body weight of litter (17.7%), a greater number of kits born alive (48.7%), higher weight of kits (87.81%) at 28 d of age, higher milk yield (43.6%) and more favourable milk conversion ratio (31.6%). Moreover, bee pollen with propolis had significantly increased plasma total protein (43.1%), albumin (45.7%), globulin (41.0) and progesterone (60.5%), and had a significantly decreased plasma cholesterol (31.1%), aspartate aminotransferase/alanine aminotransferase ratio (20.3%) compared to the control group. Does treated with growth promoters had significantly fewer services per conception (22%) and greater fertility rate (21%) compared to the control group. Inulin with or without MOS significantly increased plasma glucose (49.9 and 50%, respectively) and feed cost (90.2%) compared to the control group. Supplementation of MOS or bee pollen with or without propolis had significantly greater relative economic efficiency (61.9, 55.1 and 27.1%, respectively) than the control group. MOS and bee pollen with or without propolis are able to improve productive and reproductive performance and economic efficiency of rabbit does in comparison to the unsupplemented group.</p>

ABSTRACT Attaching and effacing Escherichia coli (AEEC) has been associated with naturally occurring attaching and effacing (A/E) lesions in weaned pigs, and although A/E lesions have been experimentally reproduced in newborn piglets, such lesions have been much more difficult to induce in older conventional pigs. Hence, the aim of this study was to examine the effect of oral administration of dexamethasone on the development of A/E lesions in weaned pigs challenged with a porcine enteropathogenic E. coli (PEPEC) strain and to investigate the involvement of local intestinal cytokine response. Dexamethasone, given orally at a dosage of 3 mg kg of body weight−1, significantly enhanced both the colonization of the challenge strain and the prevalence of foci of intimately adherent bacteria, resulting in extensive A/E lesions in the ileum, cecum, and colon of challenged pigs. We also confirmed the expression of both intimin and Tir by PEPEC strain ECL1001 in A/E lesions in vivo, which is, to our knowledge, the first report of the involvement of the latter proteins in any AEEC infections in vivo. Moreover, semiquantitative reverse transcription-PCR demonstrated that interleukin 1β (IL-1β), IL-6, IL-8, and, to a lesser extent, IL-12p40 are significantly upregulated in the ileum following challenge with strain ECL1001, whereas dexamethasone blocks such upregulation. Taken together, our results strongly suggested that host immune status influences the development of A/E lesions in weaned pigs, and it appears that IL-1β, IL-6, IL-8, and, to a lesser extent, IL-12p40 are expressed during infection of weaned pigs by PEPEC and may contribute to the natural resistance of the host against PEPEC infection.
