Anti microbial drug resistance concerns scientists all around the world epically one used as livestock feed additives. Feed grade antibiotics are given in non therapeutic doses which lead to survival of pathogenic microbes which in turn develop drug resistance, thus necessitating researchers to search for alternative ways to feed grade antibiotics besides doing least compromise on growth parameters. Organic acids are used in poultry to lower the pH of intestinal tract which favours good microbes which in turn suppress pathogenic microbes thus evicting the use of antibiotics. They are used in poultry diets and drinking water to elicit a positive growth response, improving nutrient digestibility, performance and immunity in poultry. Literature shows that organic acids have more or less pronounced antimicrobial activity, depending on both the concentration of the acid and the bacterial species that is exposed to the acid. The variability in response of organic acids and its possible mechanisms are discussed. Scope of this paper is to provide a view of the use of organic acids in the prevention of enteric disease in poultry, the effect on the gastrointestinal tract (GIT), immunity and performance of broiler or laying hens. In the current review beneficial as-pects of organic acids along with different dose combinations are discussed to promote its optimum utilization in poultry nutrition and production.

In this review article, the use of organic acids as feed additives is being examined in pig and poultry nutrition. The aim of this article was to evaluate the effect of organic acids and their salts on pig and poultry performance, to describe the organic acids used in animal nutrition, to discuss the route of administration and to investigate the mode of their action. The most widely used organic acids are formic, acetic, propionic, fumarie, citric, sorbic and butyric acid, and their salts as well. These organic acids are administered mainly through the feed, but they may be  administered through the drinking water as well. Successful utilization of organic acids in pig and poultry nutrition requires knowledge of their mode of action. It is generally accepted that organic acids and their salts lower feed and gastric pH, increasing the activity of proteolytic enzymes and, thus, improving protein digestion. Besides, they reduce the buffering capacity of the feeds, resulting in reduced intestinal colonization with pathogens. They also improve the apparent digestibility of proteins and amino acids, increase the absorption of minerals and affect the composition of intestinal microflora and mucosal morphology. Relevant experimentations suggest that the organic acids improve growth rate and feed efficiency ratio in weaned piglets and fattening pigs. Also, the organic acids improve the performance of broiler chickens when used in relatively high doses, whereas, in laying hens, they improve the absorption of macroelements, like phosphorus and calcium. The present article suggests that after the recent ban on the use of the antibiotic growth promoting substances by the EU, the use of organic acids in pig and poultry nutrition appears to be an interesting alternative. However, the effect of organic acids on performance of pigs and poultry varies considerably and, thus, further research is needed for a better understanding of the mode of action and the efficacy of these compounds.

Amino Acid Requirement

Abstract Reducing dietary crude protein in early nursery has been suggested as a way to conquer the challenge of post-weaning diarrhea. In order to meet the amino acid requirement in RCP diets, feed grade amino acids are typically used, but the detrimental effect on growth performance associated with the aggressive usage of these amino acids resulted in the establishment of dietary limits. Given the fact that protein deposition rate is the highest in young pigs, lower amino acid consumption could slow the growth rate and feed efficiency in early nursery phase. Therefore, identifying feed additives that increase nutrient retention not only can further reduce dietary nitrogen but also maintain GI tract health. Among all feed additives that exert improvements on nutrient digestibility, peptide and organic acids will be discussed here. Peptide, a di- tri amino acid, is absorbed more efficiently than free amino acids in the small intestine through a peptide transporter at the enteric site. In addition, aside from meeting the amino acid requirement, the bioactive peptide possesses functions such as antimicrobial, antioxidant, anti-inflammatory, and as a stimulated Peptide transporter associated with nutrient absorption. Hence, a dietary peptide can help pigs meet the nutrient requirement in RCP diets. Organic acids, on the other hand, have been found to lower gastric pH which improves nutrient absorption, alters microbiome structure (via bacteriostatic and bactericidal) and promotes the growth and health of animals. In addition, organic acids are a ready energy source which is especially critical since nutrient supply disruption, due to low intake during early weaning, is commonly found in weaning pigs. It is noteworthy that variations of growth-promoting effects do exist for both peptide and organic acid products. Thus, understanding the mode of action and response of dietary peptide and organic acid supplements when used across different farm settings is important to help producers decide when to transfer to an antibiotic-free, low zinc operation.

Because the application of antibiotic growth promoters (AGP) causes accelerated adverse effects on the animal diet, the scientific community has taken progressive steps to enhance sustainable animal productivity without using AGP in animal nutrition. Organic acids (OAs) are non-antibiotic feed additives and a promising feeding strategy in the swine and broiler industry. Mechanistically, OAs improve productivity through multiple and diverse pathways in: (a) reduction of pathogenic bacteria in the gastro-intestinal tract (GIT) by reducing the gut pH; (b) boosting the digestibility of nutrients by facilitating digestive enzyme secretion and increasing feed retention time in the gut system; and (c) having a positive impact and preventing meat quality deterioration without leaving any chemical residues. Recent studies have reported the effectiveness of using encapsulated OAs and synergistic mechanisms of OAs combinations in swine and broiler productivity. On the other hand, the synergistic mechanisms of OAs and the optimal combination of OAs in the animal diet are not completely understood, and further intensive scientific explorations are needed. Moreover, the ultimate production parameters are not similar owing to the type of OAs, concentration level, growth phase, health status of animals, hygienic standards, and environmental factors. Thus, those factors need to be considered before implementing OAs in feeding practices. In conclusion, the current review evaluates the basics of OAs, mode of action, novel strategies to enhance utilization, influence on growth performances, nutrient digestibility, and meat quality traits of swine and broilers and their potential concerns regarding utilization.

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.

AbstractThe rearing of piglets is the most difficult period in the pigs’ production because of their poorly developed digestive system and the low activity of digestive enzymes. Problems in nutrition and stress cause some disorders in the functioning of the digestive system leading to diarrhea and the mortality of piglets. Starting in 2006 in the EU, a total ban on antibiotics in their use as growth promoters was introduced. Since then, new and safe feed additives have been sought in order to replace antibiotics. Organic and inorganic acids as well as their salts were recognized as effective and safe additives. Due to their properties, they can improve feed palatability and digestibility, reduce the buffer capacity of feed, impact the development and functioning of the pig’s digestive system and improve the health and growth parameters. However, the effectiveness of acids is related to their qualitative and quantitative share in the feed additive. In this review, some strategies for using organic acids, their mixtures and also some new multi-component products will be discussed.

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.

AbstractSmall ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.
