Numerous efforts have been undertaken to develop suitable alternatives in order to counteract the anticipated drawbacks associated with the ban of antibiotic growth promoters (AGPs). The research purpose is to carry out the possible effect of mannan-riched fraction (MRF) and probiotic enhanced water as natural growth promoters (NGPs) on performance, relative organ weight, serum blood biochemistry, intestinal properties, and intestinal micro flora. 320 one-day-old Arbor Acres broiler were randomly allocated to 4 dietary treatments and 4 replicates of 20 birds per cage. four treatments used for research were dietary with control (T0), basal diet + MRF 80 g (T1), Drinking water + 2 mL/L combination feed additive (T2), and basal feed + MRF 80 g+ drinking water 2 mL/L combination feed additive (T3). The results showed that using mannan riched fraction (MRF) and combination with probiotic-enhanced liquid acidifier presented significant difference (P > 0.05) on body weight gain at 1-28 days and intestinal properties. On the blood biochemistry, the effect of supplementation began to reduce the amount of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) at 21 days periods. To sum up, the addition of mannan-riched fraction and combination with probiotic enhanced liquid acidifier doesn’t impacted on growth performance, and serum blood biochemistry but give significant effect on intestinal properties of broiler.

Phaleria Macrocarpa

The purpose of this study was to investigate the use of nanoencapsulation of Phaleria macrocarpa fruits extract (NEPM) in drinking water and the effect on broiler growth performance. A total number of 200 male broiler chicks, aged eight days old, were distributed into 5 treatments with 4 replicates (10 birds in each replicate). The experimental treatments consisted of the basal diet (P0; negative control), and basal diet with antibiotic tetracycline supplementation (P1; positive control), and basal diets with 2.5% of Phaleria macrocarpa fruits extract (P2), 2.5% NEPM (P3), or 5.0% NEPM (P4). The basal diet was based on yellow corn and soybean meal that contains 20.44% crude protein, 2917.47 kcal/kg metabolizable energy, 0.84% Calcium, and 0.51% available Phosphorus. The diets and drinking water was supplied for ad libitum consumption. Parameters evaluated in the current study were growth performance (feed consumption and conversation, body weight gain, water consumption, slaughter and carcass weight, and carcass percentage), Data were analyzed using analysis of variance in a completely randomized design. Orthogonal contrast tests were used to separate data with a significant difference. Results showed that supplementation of NEPM in the drinking water did not affect growth performance of broiler chicken.

Background and Aim: Wood vinegar is a product generated from the combustion and distillation of wood and other plant materials. It has been shown to suppress bacteria, resulting in healthier livestock and increased yields. This study aimed to determine the efficacy of drinking water supplemented with wood vinegar on growth performance, intestinal health, and gut microbial of broilers. Materials and Methods: A total of 120 Ross 308 1-day-old male broiler chicks were randomly distributed in a completely randomized experimental design. The study consisted of three treatments containing four replicates, with 10 birds in each. Treatments were given 0.5% and 1.0% (V/V) wood vinegar supplemented in drinking water, while no supplementation was given to the control group. The animals were raised in an open-house system. All groups were provided with a commercial diet and drinking water ad libitum. Analysis of variance was conducted using the general linear model procedure to compare the levels of wood vinegar supplementation in drinking water on growth performance, intestinal morphology, and gut microbial. Results: No significant differences (p>0.05) were found for body weight gain, feed intake, feed conversion ratio, and water consumption between groups during the starter (1-21 days old), grower (22-35 days old), and whole (1-35 days old) growth periods. Moreover, no significant differences in villi height and crypt depth (p>0.05) at 21 and 35 days of age were found. In addition, no significant difference in terms of lactic acid bacteria and Escherichia coli was found between the different treatments. Conclusion: Drinking water supplemented with wood vinegar was not found to have an effect on the growth performance and gut microbial of broiler chickens in the present study. However, the supplementation of wood vinegar in drinking water could improve intestinal morphology.

AbstractProhibition of application of antibiotic growth promoters in broiler chicken diets has resulted in increased use of herbs as natural additives in broiler feeds over the recent years. Researchers particularly look for herbs that can affect such parameters as growth performance, immune response, or treatment of certain diseases. Aloe vera is a well-known herb characterized by properties such as anti-bacterial, anti-viral, anti-fungal, anti-tumor, anti-inflammatory, immunomodulatory, wound-healing, anti-oxidant, and anti-diabetic effects. During the past years, attention has shifted toward Aloe vera as a natural additive to broiler diets, and studies have shown that Aloe vera can improve immune response and growth performance in broilers. In addition, Aloe vera is an excellent alternative for antibiotic growth promoters and anticoccidial drugs. Since Aloe vera can be used for broilers in the form of gel, powder, ethanolic extract, aqueous extract, and a polysaccharide contained in Aloe vera gel (i.e. acemannan), more studies are required to determine the best form and to compare Aloe vera with other medicinal herbs. This paper reviews effects of Aloe vera on intestinal microflora, growth performance, immune response, and coccidiosis in broiler chickens.

Abstract Background Antibiotic growth promoters are widely used to improve weight gain. However, the abuse of antibiotics can have many negative effects on people. Developing alternatives to antibiotics is an urgent need in livestock production. We aimed to perform a meta-analysis and network meta-analysis (NMA) to investigate the effects of feed additives as potential antibiotic substitutes (ASs) on bacteriostasis, growth performance, intestinal morphology and immunity. Furthermore, the primary, secondary, and tertiary ASs were defined by comparing their results with the results of antibiotics. Results Among 16,309 identified studies, 37 were summarized to study the bacteriostasis effects of feed additives, and 89 were included in the meta-analysis and NMA (10,228 pigs). We summarized 268 associations of 57 interventions with 32 bacteria. The order of bacteriostasis effects was as follows: antimicrobial peptides (AMPs) ≈ antibiotics>organic acids>plant extracts>oligosaccharides. We detected associations of 11 feed additives and 11 outcomes. Compared with a basal diet, plant extract, AMPs, probiotics, microelements, organic acids, bacteriophages, lysozyme, zymin, and oligosaccharides significantly improved growth performance (P < 0.05); organic acids, probiotics, microelements, lysozyme, and AMPs remarkably increased the villus height:crypt depth ratio (V/C) (P < 0.05); and plant extracts, zymin, microelements, probiotics, and organic acids notably improved immunity (P < 0.05). The optimal AMP, bacteriophage, lysozyme, microelements, oligosaccharides, organic acids, plants, plant extracts, probiotics, and zymin doses were 0.100%, 0.150%, 0.012%, 0.010%, 0.050%, 0.750%, 0.20%, 0.040%, 0.180%, and 0.100%, respectively. Compared with antibiotics, all investigated feed additives exhibited no significant difference in effects on growth performance, IgG, and diarrhoea index/rate (P > 0.05); AMPs and microelements significantly increased V/C (P < 0.05); and zymin significantly improved lymphocyte levels (P < 0.05). Furthermore, linear weighting sum models were used to comprehensively estimate the overall impact of each feed additive on pig growth and health. Conclusions Our findings suggest that AMPs and plant extracts can be used as primary ASs for weaned piglets and growing pigs, respectively. Bacteriophages, zymin, plants, probiotics, oligosaccharides, lysozyme, and microelements can be regarded as secondary ASs. Nucleotides and organic acids can be considered as tertiary ASs. Future studies should further assess the alternative effects of combinational feed additives.

Abstract Background Recently, restrict the use of antibiotic growth promoters by several countries and the menace of antibiotic resistant bacteria has forced to look for alternatives in rabbits. This study aimed to assess the efficiency of thyme essential oil (TEO) as a novel feed additive to dietary antibiotic to improve productive, reproductive performance and serum biochemical of male rabbit. Methods A total of one hundred and fifty 70-day-old male Californian rabbits were assigned to five dietary treatments including a basal diet as a negative control (NC), a basal diet was supplemented with an antibiotic as positive control (PC) and the basal diet was supplemented with 60, 120 or 180 mg/kg of TEO. The experiment period lasted for 60 days. Results Supplementation of TEO levels significantly (P < 0.01) increased body weight gain (BWG) and improved feed conversion ratio (FCR) of male Californian rabbits compared to NC and PC groups. Likewise, the TEO significantly improved semen characteristics of rabbits compared to NC and PC groups. Serum testosterone, aspartate transaminase (AST), alanine transaminase (ALT), urea and creatinine were improved by supplementations of thyme essential compared to NC and PC. Conclusions Based on the study results, TEO levels up to 180 mg/kg have the potential to improve productive and reproductive performances of Californian male rabbits.

The present study aimed to investigate the effects of organic acids (OA) as alternatives for antibiotic growth promoters (AGP) on growth performance, intestinal structure, as well as intestinal microbial composition and short-chain fatty acids (SCFAs) profiles in broilers. A total of 336 newly hatched male Arbor Acres broiler chicks were randomly allocated into 3 dietary treatments including the basal diet [negative control (NC)], the basal diet supplemented with 5 mg/kg flavomycin, and the basal diet supplemented with OA feed additives. Each treatment had eight replicates with 14 birds each. The results showed that AGP and OA promoted growth during day 22–42 compared with the NC group (P &lt; 0.05). OA significantly increased the jejunal goblet cell density and ileal villus height on day 42 compared with the NC group (P &lt; 0.05). Meanwhile, OA up-regulated the mRNA expression of jejunal barrier genes (Claudin-3 and ZO-1) relative to the NC group (P &lt; 0.05). Significant changes of microbiota induced by the OA were also found on day 42 (P &lt; 0.05). Several SCFAs-producing bacteria like Ruminococcaceae, Christensenellaceae, and Peptococcaceae affiliated to the order Clostridiales were identified as biomarkers of the OA group. Higher concentrations of SCFAs including formic acid and butyric acid were observed in the cecum of OA group (P &lt; 0.05). Simultaneously, the abundance of family Ruminococcaceae showed highly positive correlations with the body weight and mRNA level of ZO-1 on day 42 (P &lt; 0.05). However, AGP supplementation had the higher mRNA expression of Claudin-2, lower goblet cell density of jejunum, and decreased Firmicutes to Bacteroidetes ratio, suggesting that AGP might have a negative impact on intestinal immune and microbiota homeostasis. In conclusion, the OA improved growth performance, intestinal morphology and barrier function in broilers, which might be attributed to the changes of intestinal microbiota, particularly the enrichment of SCFAs-producing bacteria, providing a more homeostatic and healthy intestinal microecology.

We investigated the effects of a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) supplementation in 800 1-d-old male Ross 308 broiler chickens (42 ± 0.90 g) in a 7-week study. Broiler chicks were randomly allocated into one of the five dietary treatments (16 birds per pen with 10 pens per treatment). Dietary treatments consisted of corn-soybean meal based basal diet and the basal diet supplemented with blend of OAs and MCFAs at 0.25, 0.5, 0.75 g, and 1 g per kg of feed. In the current study, during the whole experimental period, the inclusion of the blend of OAs and MCFAs in the basal diet linearly improved (p < 0.05) body weight gain (BWG), feed conversion ratio (FCR), and dry matter digestibility. The increasing inclusion of the blend of OA and MCFA levels in the diets linearly decreased (p = 0.002) feed intake during d 1 to 7. Broilers fed diets containing different levels of the blend of OAs and MCFAs showed a linear increase (p = 0.006) in Lactobacillus concentrations and decrease (p = 0.014) in ammonia (NH3) at the end of the experiment. However, the blend of OAs and MCFAs did not affect carcass quality, E. coli, and Salmonella counts, as well as hydrogen sulfide and total mercaptans gas emission (p > 0.05). In conclusion, the blend of OA and MCFA supplementation positively influenced growth performance, DM digestibility, excreta Lactobacillus counts, as well as NH3 gas emission in broiler chickens.

The aim of the study was to evaluate the effect of dietary probiotics on broiler growth performance, organ development and meat quality in replacing oxytetracycline. Dietary treatments were control (basal diet without additives), antibiotic (basal diet with 0.05% oxytetracycline), basal diet with Bacillus subtilis and basal diet with Lactobacillus spp. A total of 192 birds were randomly allotted to four dietary treatments with four replicates having 12 birds each. Feed and water were supplied ad libitum. The results of the current study revealed that growth performances of broiler did not show significant difference (P>0.05) among the treatments. Body weight and weight gain were numerically higher and FCR was numerically lower in broilers fed a diet containing 2 different single strains of probiotic than control. Though there were no treatment effects (P>0.05) on the weights of the liver, heart, kidney, spleen, gizzard, intestine and dressing percentage, but abdominal fat content was found significantly higher (P<0.05) in antibiotic treated group than that of single strain probiotic (Lactobacillus spp.) feeding group. Significant differences were also observed in meat color values where antibiotic fed broiler meat showed higher redness, lower lightness and yellowness and birds fed the control feed had higher lightness and yellowness of meat than probiotic fed chicken. TBA, PH and cooking loss were not affected by the treatments. Therefore, we concluded that use of selected probiotics resulted in improved performance parameters and reduced abdominal fat pad in broiler chickens. Moreover, addition of the probiotics in broiler diet for replacing antibiotic could be utilized for safe poultry meat production.Asian J. Med. Biol. Res. June 2017, 3(2): 233-239

AbstractFermented soybean meal (FSBM) has been widely investigated as a nutritional strategy for reducing the use of fish meal (FM) and antibiotic growth promoters. Microbial fermentation by using bacteria can increase the bioavailability of nutrients and reduce the levels of antinutritional factors in soybean meal (SBM). In this study, we evaluated whether FSBM produced from Lactobacillus species and Clostridium butyricum improves growth performance, diarrhea incidence, and fecal bacteria in weaning piglets. Eighty-four crossbred male piglets with an average initial body weight of 8.36±0.63 kg were randomly allotted to 3 dietary treatments consisting of 7 replicate stalls with 4 piglets each. The dietary treatments were: (1) 3% FM in the diet; (2) 5% FSBM in the diet; and (3) 3% FM in the diet plus 4 mg/kg antibiotic growth promoters (AGP). We determined that growth performance was unaffected in FSBM-fed weaning piglets compared with a FM group. Similar to the AGP group, FSBM supplementation significantly reduced diarrhea incidence in weaning piglets. The number of fecal Lactobacillus species significantly increased in 28-day-old FSBM-fed weaning piglets compared with the other groups. Compared with AGP, FSBM has the highest inhibitory effect on the number of fecal Enterobacteriaceae at 28 d old. Furthermore, serum immunoglobulin G and immunoglobulin A levels in FSBM-fed weaning piglets significantly increased at the same age. These results together indicate that FSBM can replace FM in the diets of weaning piglets without affecting growth performance. Furthermore, similar to AGP, FSBM could improve diarrhea incidence, fecal bacteria, and immunoglobulin levels in weaning piglets. Therefore, SBM fermented by Lactobacillus species and C. butyricum demonstrated high potential for development as swine feed ingredients.

Monarda Didyma

The use of growth-promoting antibiotics in livestock faces increasing scrutiny and opposition due to concerns about the increased occurrence of antibiotic-resistant bacteria. Alternative solutions are being sought, and plants of Lamiaceae may provide an alternative to synthetic antibiotics in animal nutrition. In this study, we extracted essential oil from Monarda didyma, a member of the Lamiaceae family. We examined the chemical composition of the essential oil and then evaluated the antibacterial, antioxidant, and anti-inflammatory activities of M. didyma essential oil and its main compounds in vitro. We then evaluated the effectiveness of M. didyma essential oil in regard to growth performance, feed efficiency, and mortality in both mice and broilers. Carvacrol (49.03%) was the dominant compound in the essential oil extracts. M. didyma essential oil demonstrated antibacterial properties against Escherichia coli (MIC = 87 µg·mL−1), Staphylococcus aureus (MIC = 47 µg·mL−1), and Clostridium perfringens (MIC = 35 µg·mL−1). Supplementing the diet of mice with essential oil at a concentration of 0.1% significantly increased body weight (+5.4%) and feed efficiency (+18.85%). In broilers, M. didyma essential oil significantly improved body weight gain (2.64%). Our results suggest that adding M. didyma essential oil to the diet of broilers offers a potential substitute for antibiotic growth promoters.
