The aim of the study was to examine the possibility of replacing antibiotic growth promoters with a new probiotic preparation. One gram of the preparation contains: 4.7 × 107 of LAB (<i>Lactobacillus casei/paracasei</i> LOCK 0920, <i>L. brevis</i> LOCK 0944, <i>L. plantarum</i> LOCK 0945), 2.0 × 103 of yeast (<i>Saccharomyces cerevisiae</i> LOCK 0140) and a 50 mg of extract from Yucca Schidigera. The experiment was conducted on 99 female broilers divided into three groups consisting of 33 chickens, kept separately. A wheat- and soybean meal-based diet was divided into three parts: A (containing 1 g/kg of probiotic for starter and grower diets and 0.5g/kg for finisher diet), B (containing 14 mg/kg of flavomycin), and C (unsupplemented). The diets were fed from Day 1 to Day 41 of life. Final BW was on average 2.4 kg in all groups, FCR was 1.63 kg feed/kg BWG, neither BWG nor FCR nor mass of the liver, pancreas and gastrointestinal tract were significantly influenced by supplementing the diet with either additive. Special attention should be drawn to the fact that supplementing feeds with a probiotic preparation already after one week of breeding considerably decreased the number of <i>Clostridium</i> bacteria in broilers’ faeces. Nevertheless, it should be emphasized that in this study the excreta of chickens fed with the feed mixed with a probiotic contained the lowest changeability of the number bacteria of the <i>Enterobacteriaceae</i> family and bacteria belonging to coli groups in individual weeks of breeding. It may be concluded that the studied probiotic can be considered as a substitute for antibiotic growth promoters in broiler diets.

The aim of the study was to investigate the toxic effects of aflatoxin B1 (AFB1) and efficacy of a probiotic preparation containing L. reuteri, L. plantarum, L. pentosus, L. rhamnosus and L. paracasei and Saccharomyces cerevisiae yeasts to ameliorate their effects in broiler chickens. A total of 168 one-day-old female Ross 308 broilers were randomly allocated to six groups. Three wheat and soybean meal-based diets were prepared: Control diet and diets contaminated with 1 or 5 mg/kg AFB1 supplied in moldy wheat. All diets were unsupplemented or supplemented with probiotic, cold pelleted and fed from 1 to 35 day of life. Feeding diet with 1 mg AFB1/kg did not affect performance, but a diet with 5 mg AFB1 resulted in a significant reduction of feed intake and BWG, both diets induced liver and kidneys enlargement. The probiotic supplementation of the diets partially ameliorated those negative effects and resulted in a significant increase of AFB1 excretion. It was accompanied by the reduced level of AFB1 residues in the liver from 8.9 to 3.7 and from 11.8 to 5.9 µg/kg, in kidneys from 7.9 to 2.5 and from 13.7 to 4.1 µg/kg in birds fed the less and more contaminated diets, respectively. AFB1 exposure caused many severe histopathological changes in the liver and kidneys of broilers, probiotic supplementation significantly reduced the changes of these organs. It may be concluded that the probiotic supplementation can be used to alleviate the negative effects of contamination of broiler feed with AFB1 on bird health and product security.

AbstractNecrotic enteritis (NE) is being considered as one of the most important intestinal diseases in the recent poultry production systems, which causes huge economic losses globally. NE is caused by Clostridium perfringens, a pathogenic bacterium, and normal resident of the intestinal microflora of healthy broiler chickens. Gastrointestinal tract (GIT) of broiler chicken is considered as the most integral part of pathogen’s entrance, their production and disease prevention. Interaction between C. perfringens and other pathogens such as Escherichia coli and Salmonella present in the small intestine may contribute to the development of NE in broiler chickens. The antibiotic therapy was used to treat the NE; however European Union has imposed a strict ban due to the negative implications of drug resistance. Moreover, antibiotic growth promoters cause adverse effects on human health as results of withdrawal of antibiotic residues in the chicken meat. After restriction on use of antibiotics, numerous studies have been carried out to investigate the alternatives to antibiotics for controlling NE. Thus, possible alternatives to prevent NE are bio-therapeutic agents (Probiotics), prebiotics, organic acids and essential oils which help in nutrients digestion, immunity enhancement and overall broiler performance. Recently, probiotics are extensively used alternatives to antibiotics for improving host health status and making them efficient in production. The aim of review is to describe a replacement to antibiotics by using different microbial strains as probiotics such as bacteria and yeasts etc. having bacteriostatic properties which inhibit growth of pathogens and neutralize the toxins by different modes of action.

Public Scrutiny

The subtherapeutic use of antibiotics in animals has been under scientific and public scrutiny as antibiotic growth promoters (AGP) have been linked to the development of antibiotic resistance in bacteria, which poses a threat to human health (Smith et al., 2003). Short chain fatty acids such as butyrate are considered as potential alternative to AGP, In addition to its bactericidal activity; butyrate appears to play a role in development of the intestinal epithelium (Leeson 2005). Prebiotics (e.g. mannanoligosaccharides, MOS) are nondigestible feed ingredients that can selectively stimulate growth or metabolic activity of a limited number of intestinal microorganisms (Gibson and Roberfroid, 1995). This study was, therefore, conducted to investigate effectiveness of mannanoligosaccharides and butyric acid as potential alternatives to AGP in broilers.

Level Of Significance

This study was conducted in Chimborazo province, Riobamba Canton to evaluate the effect of threonine and the bioactive component of Saccharomyces cerevisiae on the productive performance of the broiler Cobb 500. A total of 270 one-day-old broiler chicken of both sexes were included, which corresponded to an experimental unit size of 15 birds. Two growth promoters were used for the treatments -- T1: Threonine (aminoacid) 200 g/Tn; and T2: bioactive oligosaccharides, obtained from the cell wall of selected strains of S. Cerevisiae (probiotic) 750 g/Tn. These were compared to a control group. The data were analyzed through Analysis of Variance (ADEVA). The separation of means was performed using the Tukey statistic at a level of significance of p < 0.05 and p < 0.01. The data were processed using the Infostat software version 2010. The results showed that the best productive yields were with treatment 2; the values for this treatment were: weight at 28 days: 1369.42 g; weight gain at 28 days: 48.90 g; food conversion at 28 days: 1.39 points; carcass weight: 2527.05 g; and yield to the carcass: 83.85%. Through the economic analysis, it was determined that the highest cost-benefit index was 1.30 USD with the application of T2. So according to the results, a better use of the nutrients that are present in the feed is achieved when bioactive components of S. cerevisiae are supplied in the diet of broiler chickens. Keywords: Threonine, Saccharomyces cerevisiae, productive performance, broiler, Cobb 500.

A feeding trial was conducted to evaluate the performance, serum, lipid, haematology and economic indices of broiler chickens fed diets supplemented with different levels of Chestnut (Castenea sativa) phytobiotic as a replacement for antibiotic growth promoters (AGPs). A total of 300, oneday-old cobb 500 broiler chicks were allotted in a completely randomized design to five dietary treatments each replicated thrice, with 20 chicks per replicate. Chestnutphytobiotics was included at 0, 100, 125 and 150g/100 Kg diet while Oxytetracycline was included at 111g/100kg diet. Data was collected on growth performance, haematology, serum biochemical parameters, lipid profiles and economic indices. All data collected were subjected to analysis of variance and significant differences among treatment means were compared using the Duncan's Multiple Range Test of significance. At the end of the starterphase, result showed that chicks placed on 100g phytobiotics diet had significantly (P<0.05) high final weight and weight gain than other supplemented diets and control. There was significant (P<0.05) differences in the feed conversion ratio. Feed cost per kilogram gain was significantly lower in chicks fed control diet, followed by phytobiotics, however higher feed cost per kilogram gain was recorded for chicks fed diet containing Oxytetracycline. Weight gain was significantly (P < 0.05) higher on oxytetracycline based diet (1783.2g) for finisher phase however, there was an improved values for chicks placed on phytobiotics. Glucose (206.51mg/dL) was significantly higher in treatment diet that contained oxytetracycline. Haematological indices showed that values for white blood cell (91.90x103/μL) and Heterophils (20.63%) were significantly higher in diets containing oxytetracycline than other treatment groups. Values for red blood cell, monocytes, eosinophils and basophils were significantly (P<0.05) higher in broiler chickens fed diets containing 100g phytobiotics . Chestnut phytobiotics reduced the total cholesterol values from 151.13 - 96.55mg/dL when compared to other treatment groups. There were significant(P<0.05) differences in all the villi morphometry parameters measured except for crypt depth. The mean yield cost decreased as the level of phytobiotics increased. In conclusion, supplementation of Chestnut phytobiotics reduced total cholesterol and significantly improved the final weight, weight gain, feed cost per Kg gain and feed conversion ratio for both starter and finisher at 100g/100Kg. Chestnut phytobiotic is therefore a potential replacement for antibiotic growth promoters.

The aim of this study was to evaluate the potential of two probiotic preparations, containing live lactic acid bacteria (Lactococcus lactisCECT 539 andLactobacillus caseiCECT 4043) and their products of fermentation (organic acids and bacteriocins), as a replacement for antibiotics in stimulating health and growth of broiler chickens. The effects of the supplementation of both preparations (with proven probiotic effect in weaned piglets) and an antibiotic (avilamycin) on body weight gain (BWG), feed intake (FI), feed consumption efficiency (FCE), relative intestinal weight, and intestinal microbiota counts were studied in 1-day posthatch chickens. The experiments were conducted with medium-growth Sasso X44 chickens housed in cages and with nutritional stressed Ross 308 broiler distributed in pens. Consumption of the different diets did not affect significantly the final coliform counts in Sasso X44 chickens. However, counts of lactic acid bacteria and mesophilic microorganisms were higher in the animals receiving the two probiotic preparations (P<0.05). In the second experiment, although no differences in BWG were observed between treatments, Ross 308 broilers receiving the probioticLactobacilluspreparation exhibited the lowest FCE values and were considered the most efficient at converting feed into live weight.

Phytoadditives in animal nutrition have attracted a lot of attention for their potential role as alternatives to antibiotic growth promoters. Phytoadditives are feed additives originated from plants or botanicals that are used in poultry nutrition. This chapter provides an overview about the potency of alternative additive from plants as a basis for exploring it as a phytoadditive for poultry. These substances are derived from herbs, spices, and other plants and their extracts. They are natural, less toxic, residue free and ideal feed additives for poultry when compared to synthetic antibiotics. There efficacy of phytogenic applications in poultry nutrition depends on several factors, such as composition and feed inclusion level of phytogenic preparations, bird genetics, and overall diet composition. Addition of 100 mg/kg feed essential oils consist of carvacrol, thymol and limonene in matrix encapsulation improved performance and apparent ideal digestibility of nutrients of broiler chickens. Besides enhancing performance, phytogenic also has antioxidant, the effects of which are associated with essential oils (EOs) and their components. Administration of eucalyptus and peppermint oil blends by oral (0.25 ml/L drinking water) and spray route (0.1 ml/20 ml water) reduced Newcastle disease infection in broilers. Phytoadditives have antimicrobial, antifungal, antiviral, antitoxigenic, antiparasitic and insecticidal properties. The benefits of using phytoadditives in poultry nutrition are increased feed intake, stimulation of digestion, increased growth performance, reduced incidence of disease, improved reproductive parameters, feed efficiency, profitability. Based on the latest scientific findings presented in this chapter, the following main conclusions have been drawn that phytomolecule and that bioactives have potential to be developed as an alternative additive for poultry, and that promote health.
