Poultry production is an important area of the agricultural economy. Nowadays, there is an interest in novel sources of feed additives that will improve production performance and poultry health. As an easily available and renewable biomass rich in biologically active compounds, seaweeds can meet this demand. Different forms of seaweeds–seaweed powder from naturally occurring biomass, cultivated or waste biomass, extracted compounds, post-extraction residues or liquid extracts–may be used in poultry feeding. Inclusion of this unconventional material in the poultry nutrition can positively influence the poultry performance along with its health and enrich poultry products with active compounds, such as micro- and macroelements, polyunsaturated fatty acids and pigments. Seaweeds also reduce lipids and cholesterol in eggs. Moreover, due to their unique properties, they can serve as an alternative to antibiotic growth promoters. This review presents the latest developments in the use of seaweeds in poultry nutrition, as well as its limitations.

Abstract Seaweed (known as the marine algae) has a tradition of being part of the animal feed in the coastal areas, from ancient times. Seaweed, are mixed with animal feed, because when consumed alone can have some negative effects on the animal. Seaweed are very rich in useful metabolite (pigments, carotenoids, phlorotannin, polyunsaturated fatty acids, agar, alginate and carrageenan) and minerals (iodine, zinc sodium calcium, magnesium, iron, selenium), being considered as a natural source of additives that can substitute the antibiotic usage in various animals. Inclusion of naturally available material in poultry feed additive can have a positive influence on the poultry performance and enrich the quality of their by product. As an easily available and renewable biomass rich in biologically active compounds, seaweeds can meet this demand. Different forms of seaweed powder from naturally occurring biomass, cultivated or waste biomass, extracted compounds, post extraction residues or liquid extracts may be used in poultry feeding. This study describes the nutritional values of seaweeds and their effects in poultry feed additive, and to what extent their unique properties can serve as an alternative to antibody growth promoter.

Antibiotic Growth Promoters

A growing global concern of antibiotic use in poultry diets due to its potential adverse effects on birds and human health, food safety and the environment has led to a complete ban or restricted use in some countries, and, at the same time, expanding options for the use of alternative feed additives. Multiple, rather than a single additive may replace antibiotic growth promoters (AGPs) in poultry. Blending of feeding additives and hygienic farm management, vaccination and biosecurity may help achieve good intestinal health, stabilise enteric ecosystems and result in sustainable and cost effective production performance of birds. Moreover, controlling unsolicited ingredients at the production level must have the support of different markets responsible for the supply of safe and quality poultry products for consumers. This requires the further increase and diversification of value added poultry products and the expansion of their markets through strategic planning and gradual limitation of live bird markets. More research is warranted in order to explore suitable, reliable and cost effective alternatives to AGPs for commercial use, and strategic poultry value chain development.

Natural plant bioactive compounds (PBC) have recently been explored as feed additives to improve productivity, health and welfare of poultry following ban or restriction of in-feed antibiotic use. Depending upon the types of PBC, they possess antimicrobial, digestive enzyme secretion stimulation, antioxidant and many pharmacological properties, which are responsible for beneficial effects in poultry production. Moreover, they may also improve the intestinal barrier function and nutrient transport. In this review, the effects of different PBC on the barrier function, permeability of intestinal epithelia and their mechanism of actions are discussed, focusing on poultry feeding. Dietary PBC may regulate intestinal barrier function through several molecular mechanisms by interacting with different metabolic cascades and cellular transcription signals, which may then modulate expressions of genes and their proteins in the tight junction (e.g., claudins, occludin and junctional adhesion molecules), adherens junction (e.g., E-cadherin), other intercellular junctional proteins (e.g., zonula occludens and catenins), and regulatory proteins (e.g., kinases). Interactive effects of PBC on immunomodulation via expressions of several cytokines, chemokines, complement components, pattern recognition receptors and their transcription factors and cellular immune system, and alteration of mucin gene expressions and goblet cell abundances in the intestine may change barrier functions. The effects of PBC are not consistent among the studies depending upon the type and dose of PBC, physiological conditions and parts of the intestine in chickens. An effective concentration in diets and specific molecular mechanisms of PBC need to be elucidated to understand intestinal barrier functionality in a better way in poultry feeding.

The quality and safety attributes of poultry products have attracted increasing widespread attention and interest from scholarly groups and the general population. As natural and safe alternatives to synthetic and artificial chemical drugs (e.g., antibiotics), botanical products are recently being used in poultry farms more than 60% of the time for producing organic products. Medicinal plants, and honeybee products, are natural substances, and they were added to poultry diets in a small amount (between 1% and 3%) as a source of nutrition and to provide health benefits for poultry. In addition, they have several biological functions in the poultry body and may help to enhance their welfare. These supplements can increase the bodyweight of broilers and the egg production of laying hens by approximately 7% and 10% and enhance meat and egg quality by more than 25%. Moreover, they can improve rooster semen quality by an average of 20%. Previous research on the main biological activities performed by biotics has shown that most research only concentrated on the notion of using botanical products as growth promoters, anti-inflammatory, and antibacterial agents. In the current review, the critical effects and functions of bee products and botanicals are explored as natural and safe alternative feed additives in poultry production, such as antioxidants, sexual-stimulants, immuno-stimulants, and for producing healthy products.

Poultry Nutrition

SummaryIn the context of mismanagement of natural resources going with an increasing consumption of protein from animal origin through the world population, one major challenge for the future in animal nutrition is the improvement of its efficiency and hence sustainability. Up to now, a broad range of methods like feed additives or technological treatments have been available to improve the efficiency or the production of pig-derived and poultry-derived food and hence the sustainability in pig and poultry nutrition. Nevertheless, the exact knowledge of the mode of action of these tools is a prerequisite for their successful application. Furthermore, information concerning their impact on the nutrient availability of the different feedstuffs is of great importance, in order to formulate diets that cover the animals’ requirements. Diets covering the animals’ performance level ovoid undersupplies, which can lead to health problems on the on hand, on the other hand the emissions of nitrogen are kept as low as possible.As a result, the consumption of natural resources like grains can be considerably reduced and the substitution of regional by-products from the feed and food processing industry like wheat bran, dried distillers grains with solubles or rapeseed meal can be dramatically enhanced in diets for monogastric animals, thus contributing to more sustainable livestock production. By improving the efficiency of the production of animal-derived food, the term “sustainable’’ remains highly significant. Increasing efficiency plays an important role in ensuring that the resources required for pig and poultry nutrition are foreseeably available. Currently, there is a combination of different tools like feed additives or technological feed treatments the most promising way of improving sustainability in pig and poultry production systems.

The Impact

Background: The discovery of antibiotics was a great success in control of the pathogenic infections in living beings. In addition, it also played a significant role in upliftment of the meat industry with their use as the growth promoters in the food animals including poultry. However, massive and incorrect use of antibiotics has resulted in the adverse outcome of antibiotic resistance over the years. In order to limit the antibiotic resistance at industry level itself, exploration of the possible alternatives such as probiotics is the need of the hour to replace the antibiotics in poultry industry without compromising the productivity. Hence, the present study was conducted to explore the effects of a novel probiotic bacterium, Lactobacillus fermentum NKN51 on the production performance of the broilers with an aim to replace the antibiotics in poultry production. Methods: In the present study, a total of 128 broiler birds were grouped randomly into four treatment groups which were fed basal diet (BD) along with the different levels of L. fermentum NKN51,viz.,T1 (BD+107cfu/gm), T2(BD+106cfu/gm), T3 (BD+105cfu/gm) and T4 or control (BD only) for a period of 28 days so as to observe the effect of Lactobacillus fermentum NKN51 in the starter phase of the broiler birds in terms of growth, immunity, gut health and physiology. Result: The result revealed that the group of broiler birds supplemented with Lactobacillus fermentum NKN51 at the level of 107cfu/gm of basal feed had significantly better growth performance, cell mediated and humoral immunity, gut health and jejunal histology in terms of villus height, VH:CD ratio and intestinal absorption capacity. Thus, Lactobacillus fermentum NKN51 was found as an ideal probiotic supplement exhibiting better potential in enhancing the efficiency of broiler birds in terms of improved productivity.

Lactating Cows

Dairy farming is a strategic and most efficient branch of agriculture. Milk production depends on a number of factors. The practical experience of many scientists has shown that an increase in the milk productivity of cows is possible when the rations are fed in the form of complete feed mixtures (mono feed). Despite the fact that such a feeding technology contributes to an increase in milk productivity of cows, there are problems in the new calving period, related to their health. After calving, during the milking period, the cows lose their live weight, they quickly acquire metabolic disorders (liver steatosis, ketosis, acidosis, etc.). To prevent such pathological processes, it is necessary to feed energy-compensating supplements in the new calving period. One of the solutions of this problems is the inclusion of biologically active compounds in feed mixtures. In our research these are feed additives “Ecostimul-2” and “Active Mix". In the process of experimental studies, the effect of feed additives “Ecostimul-2” and “Active Mix” during their separate and joint feeding to lactating cows in the new calving period on their milk productivity and metabolism was studied. As a result of the experimental studies, it was found that feeding the used additives to cows in the new calving period promotes an increase in milk yield and a faster recovery of reproductive functions.

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.

This review article delineates the role of chelated minerals and phytogenic feed additives (PFAs) cocktail supplementation in improving the overall health status and production performance of poultry birds and its economic effects in the poultry industry. Organically complexed minerals have many advantages over inorganic sources. It has improved absorption and efficacy, which meets the bird's requirements comfortably with a low-dose level. Hence, inorganic forms can be replaced with lower-dose levels of organic minerals without any adverse effects on production performances in broilers and layers. PFAs possess medicinal properties, such as antimicrobial, antioxidant, adaptogenic, and immunomodulatory, therefore, could be recommended as supplements. They are also growth promoters that enhance the overall health status and augment poultry birds' production performance. Furthermore, the tremendous potential of PFAs could be extracted with the recent advances in science and technology. With the advantages of organically complexed minerals and multiple beneficial applications, there is a resurgence to develop PFAs as a cocktail of organic minerals to improve the overall health status of poultry birds and augment their productivity, which, in turn, helps the poultry industry to grow decisively and economically.

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.
