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.

The removal of antibiotic growth promoters (AGPs) as feed additives in poultry nutrition from the market in many countries has compelled researchers to find unconventional and safe alternatives to AGPs. Probiotics, prebiotics, enzymes, organic acids, herbs, immune-stimulants and essential oils (EO) have been investigated as feed additives in poultry production. Cinnamon (Cinnamomum zeylanicum), one of the oldest medicinal plants and widely used around the world, can be used in poultry rations in the form of powder or essential oil. Essential oils produced from aromatic plants have become more interesting owing to their potential effects as hypocholesterolaemic agents, antioxidants, antimicrobials, antifungals and stimulants of digestive enzymes. The potential insecticidal and antimicrobial activities of EO against pathogens that cause spoilage in agriculture crops and human diseases might be attributed mainly to the high content of volatile components (mainly cinnamaldehyde, eugenol and carvacrol) in cinnamon oil. The present review focuses on the effects of cinnamon oil as a feed additive on poultry performance, carcass traits, meat quality, hypocholesterolaemic impact, antioxidant activity, immunity and microbiological aspects.

The Impact

Chicken is a major source of animal protein consumption in Indonesia. The problem facing the poultry industry is the incidence of resistance which increases mortality of the chicken production. One of the causes of resistance case is the use of antibiotics in feed additives. The public understanding about the effects of the use of antibiotic growth promoters (AGP) in chickens in antibiotic resistance and the digestive tract of chicken needs to be done to avoid the impact on economic losses and health problems. This study aims to provide an understanding of the effects of the use of antibiotic growth promoters (AGP) on antibiotic resistance and the digestive tract of broiler chickens. This study was carried out at a broiler chicken farm in Sleman, Yogyakarta. Based on the histopathological result of the digestive tract of chickens that were given antibiotics as AGP, there was no inflammation occurs, but the administration of antibiotics caused antibiotic resistance in various type of antibiotics including tetracycline (90% resistance), streptomycin (60% resistance), amoxicillin (50% resistance), erythromycin (80% resistance), and no resistance for gentamycin.

Antibiotic Growth Promoters

Abstract Biological activity of volatile plant metabolites is the property that can potentially find application in animal nutrition. Nowadays, the use of bioactive compounds is encouraged in many areas of industry and agriculture, since these substances have similar properties as withdrawn antibiotic growth promoters. Meat poultry production is focused on the maximization of performance parameters, namely rapid chicken growth with low feed consumption, and with the optimum health status of the flock. Essential oils can stimulate the growth and functioning of the body, which translates into both chicken’s health and enhanced production parameters. The substances are characterized by a range of effects, are easily biodegradable, and do not usually require a waiting period - hence they can be used in breeding broiler chickens. Given the increasing restrictions imposed on poultry production in terms of food safety and ethical aspects of husbandry, it seems appropriate to look for the use of new, natural substances to be applied in animal production. The article presents the characteristics of essential oils in this context, with a particular focus on their antimicrobial and immunostimulatory properties. The paper also describes production applications of essential oils tested in experiments on hybrid Ross 308 and Cobb 500 chickens.

The broiler industry has experienced remarkable improvements in productivity owing to high priority placed on genetic programming, nutrition and management practices. Nutrition of the meat chicken is driven by the need to satisfy the constantly increasing genetic potential, resulting in the shortening of the rearing time required to get the bird to market weight. The concept of feeding broilers a more specialised pre-starter diet for the first 10–14 days of age is gaining interest, as this now accounts for more than 20% of the time for grow-out. Specialised diets may be formulated to be highly digestible or aim to provide specific nutrients at a higher level to meet nutritional requirements of the bird. The effectiveness of specifically formulated pre-starter or starter diets depends on potential carryover effect to increase the bird performance up to the market age. There is evidence that some nutrient requirements of birds, digestible amino acids in particular, in the first 10 days of life may be higher than the current industry recommendation. Among cereals, rice with its lower non-starch polysaccharide content may be a better cereal for pre-starter diets than are corn or wheat. Inclusion of fibrous ingredients in low-fibre diets of young broilers may also stimulate gut development and enhance nutrient utilisation, leading to improved bird performance. There are inconsistencies in responses to various feed additives tested specifically for pre-starter diets of broilers. Finally, with an increasing demand for removal of antibiotic growth promoters from all broiler feeds, focus on formulations to ensure sustainable growth at start will gain importance.

Low regulations for feed additives use, has been changed in EU as well as in our country, especially in use of antibiotics as growth promotors. Along years it has investigated an alternative for antibiotics as growth promotors. Essential oilsand organic acids are one of alternative feed, which acting in a few of the most important directions: as antioxidants, metabolic upgraders, growth promotors and development of pathogenic microorganizms controllers, including moulds and bacterias and as environmental protecting through control of amonia and nitrogen excretion. The objective of this paper was to determine the composition of essential oils in a commercial product which, in combination with the blend of organic acids may be used in poultry nutrition as an alternative to antibiotic growth promoters and establish impacts on performance parameters in broilers and microbiological properties of feces. Obtained results showed that the product contained an essential oil in which over 75% of total mass account for 2-phenol-carvacrol and eugenol. Tested product has been found to have positive effects in reduced mortality (from 4,45% to 1,5%), higher body weight by 5,55% and decreased feed conversion by 9.9%. Significant positive effect has been shown in reduction of abdominal fat content, by 70%, and it can be concluded that product in question may be successfully used in poultry nutrition.

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.

Essential oils (EO) are being considered as possible alternatives to in-feed antibiotic growth promoters in pig nutrition. The effects of an EO mixture consisting of limonene, eugenol and pinene (10.0, 2.0, and 4.8 mg/kg diet, resp.) on gut physiology and ecology were studied in piglets. The experiment was conducted at low (commercial farm) and high hygienic conditions (experimental farm), to elucidate interactions between EO supplementation and husbandry methods. Piglets were weaned at 28 days of age, when they were offered either a control diet (C) or C with EO. Four piglets were sacrificed in each group on day 29, 30, 33 and 39. Digesta from the third distal part of the small intestine and from the colon were sampled and analysed for pH, dry matter, lactic acid, short chain fatty acids and ammonia concentrations. Enterobacteria, enterococci, lactobacilli and yeast counts were obtained by plating. Genomic DNA was extracted from digesta and polymerase chain reaction—denaturing gradient gel electrophoresis was performed. Individual microbial communities were identified at each farm. Age affected the intestinal parameters. No effects of the EO with exception for a significant reduction in colon bacterial diversity at 39 days of age could be recorded at experimental farm.
