Feed of commercial broiler fortified by the external sources of vitamin and minerals which is expensive and increase the cost of feed. Blue green algae (Spirulinaplatensis) would be an alternative to those synthetic micronutrients after production in laboratory scale was studied in broiler.Spirulinaplatensiswas cultured in inorganic media contained macronutrients NaHCO3, K2HPO4, NaNO3, K2SO4, NaCl, MgSO4.7H2O, CaCl2, and FeSO4.2H2O and micronutrient solution containing H3BO4, MnCl2.4H2O, ZnSO4.7H2O, CuSO4.5H2O, MoO3, CoCl2.6H2O. Media was autoclaved and Spirulinawas cultured for 12 hours lighting with continuous aeration for 15 days to use in poultry feed. Day old broiler chick (180) was reared offering starter mash diet for 7 days. Birds were divided into 6 groups having 30 birds in each (10 per cage). Birds were offered 1. Control diet, 2. 75% premix+25% Spirulina, 3. 50% premix+50% Spirulina, 4. 25% premix+75% Spirulina, 5. 0% premix+100% Spirulina and 6. 0% premix+0% Spirulina (negative control). Spirulinawas calculated on DM basis added minerals in the media. After 21 days (28 day old) final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where higher (P<0.5) weight observed in Spirulinagroup (5). Feed intake was observed more or less similar in all groups (1483±24g). Feed conversion ratio was 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (P<0.5) where higher in negative control group (6) and control group (1), but was lowest in 75% Spirulinagroup (4) and highest (100%) Spirulina group (5). Ash% is also highest in 100% Spirulina group 5 (55.07) than any other group. Considering growth performance of broiler, complete replacement of vitamin-mineral premix could be possible by cultured Spirulinaalong with media in broiler diet. Bang. J. Anim.

The main purpose of this study was to explore the effects of Spirulina (Spirulina platensis) as a feed supplement by replacing Vitamin-Mineral Premix on the performance of broiler. The study explored that final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where significantly (p<0.5) higher weight observed in Spirulina group (5) but lower in negative control group (6). Feed intake observed more or less similar in all groups (1483±24g; p>0.5). Feed conversion ratio (kg FI/kg LWG) observed significantly different like 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (p<0.5) where higher in negative group (6) and control group (1), but is lowest and similar in 75% Spirulina group (4) and highest (100%) Spirulina group (5). %Ash of different dietary groups were 46.35, 46.54, 48.93, 49.93, 55.07 and 46.92 of group 1, 2, 3, 4, 5 and 6 respectively. The %ash of bone was gradually increased among dietary groups and the best result was obtained in 100% Spirulina group 5 (55.07). It also revealed that diets containing no vitamin-mineral premix with 100% Spirulina improve the performance of broiler. The findings suggest that poultry farmer can use spirulina as a feed item for broiler for more yield.

This study evaluated the effect of ginger on the growth performance, carcass quality of broiler chickens. 20 broiler chickens were randomly selected into two treatment groups identified as T1 and T2 with a positive control and a negative control group. Each treatment contained with five birds. Birds on T1 were treated with 1% ginger extract and T2 was treated with 2% ginger extract via drinking water. Significant variations (p<0.05) existed between the control and other treatments in mean final body weight, dressed weight, daily feed intake and feed conversion ratio. At the end of experiment (35th day) for 1% ginger extraction treatment the live body weight is 1746gm (p<0.05), dressing weight 1106.4 (p<0.05) and FCR is 1.67(p<0.05). The usage of the test ingredients had a significant effect (p<0.05) on dressing percentage. Supplementation of ginger improves the performance of broilers when added at the rate of 1% of broiler ration and can be a possible alternative to antibiotic growth promoter in the feeding of broiler chicken.Asian J.

The purpose of this study was to develop a mouse model of asthma (MMA) using house dust mite Dermatophagoides pteronyssinus (Der p) extract. Methods. BALB/c mice were i.p. immunized with different doses of Der p lyophilized extract three times in three week interval in the mixture with Al(OH)3. 8 weeks after the final immunization mice were challenged with Der p during five consecutive days by intranasal applications (INA) or aerosol administration (AA). All mice were divided into 5 experimental groups: group 1 was immunized with 50 ^g/mouse of Der p (in protein equivalent) in the mixture with 2 mg/mouse Al(OH)3 and challenged by INA; group 2 was immunized in the same way and challenged by AA; group 3 was immunized with 100 ^g/mouse Der p in the mixture with 2 mg/mouse of Al(OH)3 and challenged by INA; group was immunized in the same way and challenged by AA; group 5 (negative control) was immunized and challenged with saline. 24 hours after the last challenge airway hyperresponsiveness (AHR) to different concentrations of metha-choline was evaluated in all groups by whole-body plethysmography. 48 hours after the last challenge in all groups blood was collected for differential cell count, brochoalveolar lavage fluid (BALF) was sampled for the determination of inflammatory cells and lungs were removed for histological analysis. Histopathological changes in lungs (allergic inflammation) were graded according to semi-quantitative scoring system. Anti-Der p IgE, IgG1 and IgG2a antibodies in individual sera samples were detected by ELISA seven days after the last immunization and 48 hours after the challenge. Results. The levels of anti-Der p IgE antibodies in groups 1-4 before as well as after the challenge were substantially higher than that of in the group 5 (negative control). The highest level of serum Der p-specific IgE antibodies was observed in the group 2. The levels of anti-Der p IgG1 and IgG2a antibodies in the groups 1-4 during all periods of observation were higher than that of group 5 (negative control). At the same time the maximal levels of anti-Der p IgG1 and IgG2a antibodies were observed in group 3 both after immunization and after challenge. The maximum of AHR was observed in the groups 1 and 3 challenged by INA. Analysis of cell composition in BALF demonstrated significant elevated number of eosinophils in group 3 in comparison with group 5 (negative control) and other experimental groups. Regarding peripheral blood leukocyte count we observed decreasing of band neutrophils in group 4 and increasing of segmented neutrophils in groups 1 and 3 in compare to group 5 (negative control). In group 1 we found statistically significant decreasing of lymphocytes and increasing of eosinophils in compare to negative control group 5. Histological picture of general allergic inflammation in lungs as well as peribronchial and perivascular infiltration with inflammatory cells were the most noticeable (according to score system) in group 3 in comparison with negative control group and other experimental groups. Conclusion. Data obtained indicate that immunization (sensitization) of mice with Der p in a dose 100 μg/mouse together with Al(OH)3 and challenge with Der p by mean of intranasal applications is a suitable approach for modeling of mouse allergic asthma.

<p>Una estrategia para mejorar la salud del tracto gastrointestinal en pollos de engorde es incluir productos novedosos como los aditivos funcionales entre los que se encuentran las levaduras, caracterizadas por su papel beneficioso en la salud animal. En este estudio se evaluó el valor nutricional de tres cepas nativas de levaduras, aisladas de frutales de Colombia. Se utilizaron 240 pollos machos para evaluar los efectos de levaduras en el desempeño, calidad de la canal, parámetros hematológicos y del corazón. Los pollos se distribuyeron al azar en seis tratamientos: tres diferentes levaduras nativas (0,5% inclusión en la dieta), dos controles positivos (inclusión de dos levaduras comerciales) y un grupo control negativo sin levaduras. Las aves que fueron alimentadas con las levaduras comerciales presentaron menor consumo de alimento total (-73,7 g) comparado con los grupos a los que se les suministró levaduras nativas. Por consiguiente, el peso corporal final fue más alto para los grupos de levaduras nativas comparado con las levaduras comerciales (98,9 g/ave, <em>p </em>&lt; 0,01). Los pollos alimentados con levaduras presentaron mejor conversión comparados con el grupo control. El peso de la canal y la pechuga fueron más altos para los grupos alimentados con levaduras (<em>p </em>&lt; 0,05). Se concluye que las levaduras nativas pueden tener un efecto beneficioso en el desempeño de pollos de engorde, y algunas levaduras nativas podrían mejorar las características de calidad de carne como la terneza. Aunque se requiere mayor investigación, pueden considerarse las levaduras nativas como aditivos funcionales prometedores para los pollos de engorde.  </p><p> </p><p><strong>Evaluation of three native Colombian yeasts as feed additives for broilers</strong>  </p><p>A strategy to improve the health of the gastrointestinal tract in broilers is to include novel products such as functional feed additives. Among these, yeasts have been recently reported to play a beneficial role as a feed additive. The objective of this study was to evaluate the nutritional value of three strains of yeasts, isolated from native fruits in Colombia. A total of 240 male broilers were used, and the effects of yeasts on performance, carcass quality, blood and heart parameters were evaluated. Chicks were randomly distributed in six treatments: three different native yeasts (0.5% of inclusion in the diet), two positive controls added with commercial yeasts and a negative control group without yeasts. Chicks fed with yeasts commercial had lower total feed intake (-73.7 g) compared with the native yeast groups. Therefore, final body weight was higher for the native yeast groups compared with the commercial yeasts (98.9 g/bird, <em>p </em>&lt; 0.01). Chicks fed native yeasts tended to have better feed conversion ratio (intake/gain) compared with the control group. Carcass and breast weights were higher for the yeasts groups (<em>p </em>&lt; 0.05). It is concluded that native yeasts can have a beneficial effect on broiler performance, and some native yeasts could also improve meat quality traits such as shear force. Although more research is required, native yeasts should be regarded as relevant and promising functional additives for broilers. </p>

Background:: Probiotic cellular components could be an interesting alternative to live probiotics, which could potentially cause safety problems in open aquatic environments. Objective:: The cell wall (CW), peptidoglycan (PG) and lipoteichoic (LTA) were extracted from probiotic strain of Bacillus pumilus SE5, and these biomolecules were used to develop the possible application in fish aquaculture. Methods:: Grouper (Epinephelus coioides) juveniles were fed with either a basal control diet or the basal diet supplemented with CW, PG and LTA respectively for 60 days, and the growth performance, digestive enzymes activities, serum immune responses and immune genes expression in head kidney were determined. Results:: Dietary supplement PG and LTA significantly improved final body weight (FBW), weight gain rate (WGR), specific growth rate (SGR) and protein efficiency ratio (PER), while significantly decreased feed conversion ratio (FCR) was noticed in all the treatments compare with the control group. Dietary supplements of CW, PG and LTA enhanced the activity of trypsin, lipase and amylase activities in liver. Serum complement C3 and IgM levels as well as AKP, ACP and SOD activities elevated significantly in fish fed the PG and LTA containing diets. Furthermore, PG and LTA containing diets significantly up-regulated expression of TLR2, NOD2, IL-8, IgM and three antibacterial peptides genes (epinecidin-1, hepcidin- 1 and β-defensin) in the head kidney. Conclusion:: PG and LTA originated from probiotic B. pumilus SE5 could effectively enhance the growth performance, feed utilization, digestive ability and boost innate and adaptive immune system of E. coioides.

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

Abstract Two performance studies were conducted to investigate the effects of 3 different sources of Cu on production parameters of piglets. A total of 256 piglets weaned at 24 ± 2 d were randomly allocated into 4 treatments with 10 or 8 replicates per treatment of 4 or 3 piglets per pen in Exp. 1 and 2, respectively. The experimental period was divided into 3 feeding phases: Phase 1 (24 to 35 d), Phase 2 (36 to 49 d), and Phase 3 (50 to 70 d). Treatments included a Control group (fed 10 mg/kg of Cu from CuSO4), a group fed 160 mg/kg of either CuSO4 (CuSO4-160) or tri-basic copper chloride (TBCC), and a group fed Cu methionine hydroxy analogue chelated (Cu-MHAC) at 150, 80, and 50 mg/kg in Phases 1, 2, and 3, respectively. The methionine value of Cu-MHAC was accounted during diet formulation to achieve the same levels of methionine across treatments. Phases 1 and 2 diets contained 2,200 and 1,500 ppm of ZnO, respectively; and antibiotics were used as growth promoters. Performance parameters were analyzed as completely randomized block design, in which each experiment was considered as a block. In trial 2, blood serum and mucosal samples, from the fundic region of the stomach, were collected from 1 piglet per replicate at day 70 and tested for serum growth hormone levels (GH) and ghrelin mRNA expression, respectively. The contrast between Cu-MHAC vs. CuSO4-160 + TBCC showed that piglets fed Cu-MHAC exhibited better feed conversion ratio (FCR) in all feeding phases compared with feeding inorganic Cu (P < 0.05). Overall, feeding Cu-MHAC improved body weight (BW), BW gain, feed intake (FI), and FCR vs. Control diet fed piglets; yet, it improved BW and FCR vs. TBCC fed piglets, and improved BW, BW gain, and FI vs. CuSO4-160 fed piglets (P < 0.05). Feeding TBCC promoted similar performance than feeding CuSO4-160, regardless of age (P > 0.05). Both ghrelin expression and growth hormone serum levels were significantly increased by feeding Cu-MHAC vs. Control diet fed animals (P < 0.01). Feeding CuSO4-160 upregulated ghrelin expression vs. Control (P < 0.01) while GH serum levels and ghrelin expression did no change by feeding TBCC compared with Control diet fed animals (P > 0.05). It was concluded that feeding Cu-MHAC at the levels tested herein can improve growth performance of piglets beyond feeding 160 ppm of either CuSO4 or TBCC, which may be partially explained by the increased expression of ghrelin and GH serum levels.

Yucca Schidigera

Ammonia is a critical hazardous nitrogen metabolic product in aquaculture. Despite trials for its control, ammonia intoxication remains one of the most critical issues to overcome. In this study, we explored the modulatory effect and potential mechanism by which Yucca schidigera extract (YSE) can ameliorate ammonia intoxication-induced adverse effects on tilapia health and metabolism. A total number of 120 Nile tilapia were evenly assigned into four groups with three replicates each. The first group served as normal control group; the second group was exposed to ammonia alone from the beginning of the experiment and for four weeks. The third group was supplied with YSE in water at a dose of 8 mg/L and exposed to ammonia. The fourth group was supplied with YSE only in water at a dose of 8 mg/L. YSE supplementation succeeded in improving water quality by reducing pH and ammonia levels. Moreover, YSE supplementation markedly alleviated chronic ammonia-induced adverse impacts on fish growth by increasing the final body weight (FBW), specific growth rate (SGR), feed intake and protein efficiency ratio (PER) while reducing the feed conversion ratio (FCR) via improvements in food intake, elevation of hepatic insulin-like growth factor (ILGF-1) and suppression of myostatin (MSTN) expression levels with the restoration of lipid reserves and the activation of lipogenic potential in adipose tissue as demonstrated by changes in the circulating metabolite levels. In addition, the levels of hepato-renal injury biomarkers were restored, hepatic lipid peroxidation was inhibited and the levels of hepatic antioxidant biomarkers were enhanced. Therefore, the current study suggests that YSE supplementation exerted an ameliorative role against chronic ammonia-induced oxidative stress and toxic effects due to its free radical-scavenging potential, potent antioxidant activities and anti-inflammatory effects.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.
