Hajibeglou Abasali,Sudagar Mohamad
Journal of Aquaculture Feed Science and Nutrition , 2012, DOI: 10.3923/joafsnu.2010.11.15
Abstract: A study to determine the effect of varying dietary probiotic levels on the reproductive performance of a fresh water ornamental species, the swordtail (Xiphophorus helleri) was carried out. The commercial probiotic, Primalac were mixed thoroughly with the artificial feeds at concentration of 0.0% (A), 0.04% (B), 0.09% (C) and 0.14% (D) and fed to healthy fish for a period of 26 weeks. Results showed that supplementation of feed with probiotic increased significantly (p<0.05) the Gonadosomatic Index (GSI), fecundity and fry production of female broodstock. Fry production, fecundity and fry survival were significantly higher in group B as compared to the group A (control) (p<0.05). The highest significant Gonadosomatic Index (GSI) and fry weight were observed in group B (p<0.01). The fish of experimental groups B and A recorded the lowest and highest deformed fry (%), respectively. Based on these data, it is concluded that female swordtail broodstocks benefit from inclusion of Primalac in diet during their reproductive stages. Further, study in needed into the mechanism(s) of action for probiotics such as Primalac and their application in aquaculture.

Abstract: This work studied the effect of protein malnutrition on the hemato-immune response to the respiratory challenge with Streptococcus pneumoniae and evaluated whether the dietary recovery with a probiotic strain has a beneficial effect in that response. Three important conclusions can be inferred from the results presented in this work: a) protein-malnutrition significantly impairs the emergency myelopoiesis induced by the generation of the innate immune response against pneumococcal infection; b) repletion of malnourished mice with treatments including nasally or orally administered Lactobacillus rhamnosus CRL1505 are able to significantly accelerate the recovery of granulopoiesis and improve innate immunity and; c) the immunological mechanisms involved in the protective effect of immunobiotics vary according to the route of administration. The study demonstrated that dietary recovery of malnourished mice with oral or nasal administration of L. rhamnosus CRL1505 improves emergency granulopoiesis and that CXCR4/CXCR12 signaling would be involved in this effect. Then, the results summarized here are a starting point for future research and open up broad prospects for future applications of probiotics in the recovery of immunocompromised malnourished hosts.

Abstract: Background Lactobacillus rhamnosus CRL1505 (Lr) administered during the repletion of immunocompromised-malnourished mice improves the resistance against intestinal and respiratory infections. This effect is associated with an increase in the number and functionality of immune cells, indicating that Lr could have some influence on myeloid and lymphoid cell production and maturation. Objective This study analyzed the extent of the damage caused by malnutrition on myeloid and lymphoid cell development in the spleen and bone marrow (BM). We also evaluated the impact of immunobiotics on the recovery of hematopoiesis affected in malnourished mice. Methods Protein malnourished mice were fed on a balanced conventional diet for 7 or 14 consecutive d with or without supplemental Lr or fermented goat's milk (FGM). Malnourished mice and well-nourished mice were used as controls. Histological and flow cytometry studies were carried out in BM and spleen to study myeloid and lymphoid cells. Results Malnutrition induced quantitative alterations in spleen B and T cells; however, no alteration was observed in the ability of splenic B cells to produce immunoglobulins after challenge with LPS or CpG. The analysis of BM B cell subsets based on B220, CD24, IgM and IgD expression showed that malnutrition affected B cell development. In addition, BM myeloid cells decreased in malnourished mice. On the contrary, protein deprivation increased BM T cell number. These alterations were reverted with Lr or FGM repletion treatments since normal numbers of BM myeloid, T and B cells were observed in these groups. Conclusions Protein malnutrition significantly alters B cell development in BM. The treatment of malnourished mice with L. rhamnosus CRL1505 was able to induce a recovery of B cells that would explain its ability to increase immunity against infections. This work highlights the possibility of using immunobiotics to accelerate the recovery of lymphopoyesis in immunocompromised-malnourished hosts.

Abstract: This study was conducted to investigate the effects of probiotic and/or prebiotic supplementation on growth performance and serum IgG concentrations in broilers. One thousand two hundred one-day old Ross-308 broiler chicks of mixed sex were randomly divided into four treatment groups of 300 birds each. The treatments were: Starter diets: 1) Unsupplemented control diet; 2) Probiotic (Bio-Plus 2B 0.05%); 3) Prebiotic (Bio-Mos 0.2%); 4) Probiotic and Prebiotic mixture (Bio-Plus 2B 0.05% and Bio-Mos 0.2%). The grower diets were: 1) Control with no supplements; 2) Probiotic (Bio-Plus 2B 0.05%); 3) Prebiotic (Bio-Mos 0.1%); 4) Probiotic and Prebiotic mixture (Bio-Plus 2B 0.05% and Bio-Mos 0.1%). Each treatment group was further sub-divided into five replicates of 60 birds per replicate. The chicks were fed the broiler starter diet for the first 21 d and the broiler grower diet between days 22 and 42. Dietary probiotic and/or prebiotic supplementation did not significantly affect body weight, body weight gain, feed intake, carcass weight, carcass yield or concentration of immunoglobulin (IgG) in the serum. However, feed conversion ratio was improved significantly in the supplemented treatments compared to the unsupplemented control. Probiotic and/or prebiotic supplementation did not significantly affect any of the examined parameters except for an improved feed conversion ratio.

Abstract: The effects of a multi-strain probiotic (protexin) on broiler growth performance, carcass parameters and economic efficiency were studied. For this purpose, 270 day-old broiler chicks were randomly divided into three experimental groups A, B and C, with 90 chicks in each group having three replicates. Group A was fed commercial broiler diet without supplementation of protexin (control) and groups B and C were fed diets containing protexin 100 and 110g/t in starter and 50 and 55 g/t in finisher diets, respectively. Feed and water were offered ad libitum. The results showed that weight gain and feed conversion ratio were significantly (p<0.05) improved in chicks fed on protexin-supplemented diets compared to control diets. Weight gain of the chicks fed on diet C was significantly (p<0.05) better than chicks on diet B. Feed conversion ratio was non-significantly different in both the protexin-supplemented groups. Differences in feed intake, meat composition, dressing percentage and empty organ weights among all the diets were non-significant. However, abdominal fat content was reduced significantly (P<0.05) in supplemented groups. The study suggests that protexin supplementation is beneficial for better weight gains, feed efficiency and economic efficiency in broiler chicks.

International Journal of Poultry Science , 2005,
Abstract: The present study was carried out to determine the influence of dietary probiotic (115-Biogallinox; containing Saccharomyces cerevisiae at 4 x 108 colony forming units/g) on growth, slaughter and carcass characteristics of broilers slaughtered at different ages (35, 42 and 49 days). Day-old male Ross-308 chicks (n = 336) were weighed and randomly assigned to three dietary treatment groups [P0 (control): 0 g probiotic/kg; P1: 1 g probiotic and P2: 2 g probiotic/kg] as a 3x3 factorial arrangement. Each treatment group was replicated eight times as subgroups, comprising of 14 birds each. The broiler chickens were grown on starter (0 to 21 days) and finisher (to 35, 42 and 49 days) diets calculated to meet NRC recommendations. Body weight and feed consumption were determined weekly during the study. Means to slaughter age of body weight, daily weight gain, daily feed consumption, feed efficiency and mortality were 2524.5, 50.7, 94.4 g, 1.86 and 1.8% for P0 group; 2559.1, 51.4, 94.8 g, 1.85 and 0.0% for P1 group; 2548.3, 51.2, 95.9 g, 1.88 and 1.8% for P2 group, respectively. None of the live performance variables investigated differed significantly between control and probiotic treatment. Similarly, probiotic treatment had no effect on the hot and cold carcass weight, carcass yield and the weight of carcass cuts and the abdominal fat pad. Means for these slaughter variables were 1543.8, 1521.3 g, 74.0, 73.4%, 31.0 g for P0 group; 1561.1, 1539.4 g, 74.2, 73.6%, 30.2 g for P1 group; 1558.7, 1535.2 g, 74.1, 73.5% and 31.0 g for P2 group, respectively. However, slaughter age had a highly significant effect on the final body weight slaughter variables mentioned above. In this experiment probiotic supplementation of broilers, up to the level of 4 x 108 colony forming units/kg feed, did not significantly affect the live performance and slaughter variables investigated.

Journal of Animal and Veterinary Advances , 2012,
Abstract: This study was carried out to determine the effect of dietary supplementation of combiotics (probiotic+prebiotic, Makroton ) on body weight gain, feed consumption, feed conversion rate, carcass quality and serum biochemical parameters. A total of 264 daily Japanese quail chicks (Coturnix coturnix japonica) were used in this experiment. They were divided into 1 control and 3 treatment group each containing 66 chicks. Each group was divided into 3 subgroups each containing 22 chicks. The experimental period lasted 35 days. Control group was fed with unsupplemented basal diets. 0.5, 1.0 and 1.5 g kg-1 combiotic was added to diets of treatment groups 1, 2 and 3, respectively. At the end of the experiment, the effect of combiotic supplementation to diet on the BWG, FC, carcass yield of and serum biochemical parameters of quail were not statistically significant among the groups (p>0.05). FCR rate was determined as 3.19, 3.15, 3.14 and 2.87, respectively.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.2980.2985
Abstract: This study was conducted to test the hypotheses that dietary L-arginine supplementation may enhance the immune responses and resulting in the clearance against PCV2 in experimentally infected mice. The measured variables include: the PCV2 virus load in liver, spleen, heart, lung, kidney, ovary and serum on 3rd, 5th, 7th, 9th and 11th day post infection (dpi); serum Interleukin-2 (IL-2), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Interferon alpha (IFN-α), Interferon gamma (IFN-γ) and C-Reactive Protein (CRP) levels on 3rd, 5th, 7th, 9th and 11th dpi; serum Total Superoxide Dismutase (T-SOD) activity on 3rd, 5th, 7th, 9th and 11th dpi. Results showed that arginine supplementation could significantly increase the serum IL-2 levels on the 9th and 11th dpi; significantly increase the serum IFN-α and CRP levels on the 11th dpi; significantly increase the serum IFN-r levels on the 7th dpi and significantly decrease the serum IL-6 levels on the 9th dpi. Meanwhile, the PCV2 virus genome was detected sporadically. Collectively, dietary L-arginine supplementation had beneficial effects on the cytokines profile in the PCV2 infected mouse and maybe could delay the PCV2 replication and/or clear the PCV2 in mouse model.

Abstract: Wistar Kyoto (WKY) rats were fed a high (HK) or low potassium (LK) diet for six weeks from six weeks of age. At the end of treatment, cerebral ischemia was induced by middle cerebral artery (MCA) occlusion and the resultant infarct was quantified and expressed as a percentage of the hemisphere infarcted (%HI). MCA structure was assessed in an additional group of rats using a pressurized arteriograph.The cerebral infarct was significantly smaller in rats fed the HK diet, compared to rats fed the LK diet (21 ± 5.4 vs 33.5 ± 4.8 %HI HK vs LK p < 0.05). Vessel structure was improved in WKY rats fed the HK diet as indicated by an increase in the MCA lumen (298 ± 6.3 vs 276 ± 3.9 μm HK vs LK p < 0.05) and outer diameters (322 ± 7.6 vs 305 ± 4.8 μm HK vs LK p < 0.05). Wall thickness and area were unchanged, suggesting an outward euthrophic remodelling process. The HK diet had no effect on body weight or telemetry blood pressure.These studies are the first to show a beneficial effect of dietary potassium in rats with normal blood pressure.Epidemiological studies show that potassium intake correlates inversely with the incidence of cerebrovascular events [1-4]. It has been clear for some time that a high potassium diet reduces the number of hemorrhagic strokes in stroke prone spontaneously hypertensive rats (SHRSP) [5,6] and reduces the risk of stroke in humans [1-3]. We have also previously shown that administration of spironolactone, a potassium sparing drug, reduces the ischemic cerebral infarct size in SHRSP [7]. We have recently shown that dietary potassium supplementation also reduces the size of ischemic cerebral infarcts in SHRSP and improves the structure of the MCA [8]. Interestingly, dietary potassium supplementation did not alter blood pressure in the SHRSP fed a normal sodium diet. This presents the possibility that the effects of potassium supplementation are blood pressure independent and may also occur in normotensive rats.Sixty to eighty percent of ischemic
