Phytogenic additives and organic acids in broiler chicken diets

Abstract

-The experiment evaluated the influence of isolated or associated phytogenic additives (PA) and organic acids (OA) on nutrient digestibility, performance and carcass characteristics of broiler chickens. Two experiments were conducted in a completely randomized design with a 2 × 2 + 1 factorial arrangement of treatments (with or without PA × with or without OA + antibiotic performance enhancer and anticoccidial). In the first experiment, two metabolic tests were conducted to determine the metabolizability coefficients of the nutrients of starter and growth diets. In the second experiment, 2520 one-day-old chicks were housed in 40 experimental units to evaluate the performance and carcass characteristics. The phytogenic additives and organic acids, isolated or associated, improve the nutrient digestibility of the diet and replace the growth-promoting antibiotics. The use of organic acids isolated or associated with phytogenic additives in broiler diets improves broiler performance in comparison with free antibiotic performance enhancer at 42 days of age. Isolated or associated phytogenic additives and organic acids provided better carcass characteristics.

Testing Novel Eubiotic Additives: Its Health and Performance Effects in Commercially Raised Farm Animals

“…It seemed that the use of eubiotic mixture 2 containing several types of active agents (probiotics, enzymes, organic acids etc.,) may induce remarkable growth promoting effects. This result confirmed all the results obtained from previous studies regarding the use of individually supplemented probiotics, enzymes and organic acids in similar cases (Ambriz-Vilchis et al, 2017;Yasar et al, 2016;Ayaşan, 2016;Elala and Ragaa, 2015;Yasar and Desen 2014;Fascina et al, 2012). Eubiotic mixture 3 was used as silage additive.…”

“…Generally, the synbiotics products with a mixture of pro-ad pre-biotics may provide eubiotic effects (Zhang et al, 2010;Pandey et al, 2015). Using organic acids with or without phytogenic additives as an eubiotic mixtures (Ragaa and Korany, 2016;Polycarpo et al, 2017) has been successfully used an alternative to the feed antibiotics in meat-type poultry (Fascina et al, 2012). However, further formulations of synbiotic mixtures with organic acids, essential plant oils and feed grade enzymes may become too complex, and could not be fit for the purpose.…”

Effects of Korean ginseng (<i>Panax ginseng</i> C.A. Meyer) root extract on egg production performance and egg quality of laying hens

“…Many herbs and plant extracts possess antimicrobial activities and antioxidant properties that make them useful as natural animal feed additives (Faixova & Faix, 2008). These extracts present a mechanism of action based on the alteration of the intestinal microbiota, increased enzyme secretion, improved immune response, morpho-histological maintenance of the gastrointestinal tract and antioxidant activity (Brugalli, 2003;Fascina et al, 2012). Several studies have demonstrated their in vitro effect against pathogens because of antimicrobial, antifungal and anthelmintic activities, in addition to powerful antioxidant effects (Kamel, 2000;Petrolli et al, 2012).…”

Advances in role of organic acids in poultry nutrition: A review

“…In vast options of feed additives organic acids have emerged as to have growth promoting properties and can be used as alternatives to antibiotics (Fascina et al, 2012). The pig industry has received much more attention as compared to poultry which might be due to inconsistent reported effects.…”
