Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
Dr. Marcos Rostagno, Global Senior Technical Consultant at Elanco Animal Health, spoke to us at Avicolas con Porcinos 2016 in Buenos Aires about the recent global tendencies on reduction of antimicrobials in poultry and how can producers make adjustments to comply with changes in regulations....

The aim of the study was to determine the effect of dietary supplementation of organic acids on the performance, intestinal histomorphology, and blood biochemistry of broiler chicken. The birds in the control (T1) group were fed the basal diet whereas in other treatment groups basal diet was supplemented with 2% butyric acid (T2), 3% butyric acid (T4), 2% fumaric acid (T4), 3% fumaric acid (T5), 2% lactic acid (T6), and 3% lactic acid (T7). Broiler chicken...

Hello. Dear collegues , please help me with some information about Herbal methionine ( if you use this or you ever use this kind of product. I have in this moment in my storage 1000kg Methiomax from AlfaFacts ( contain andrographis paniculata 40%, ocimum sanctum 30% and azadirachta indica 30%) I took this product from curiosity. What do you know about this product : can be used for poultry and pigs as herbal methionine or not. Is allright to be used or can be...

This paper was published in "British Poultry Science Volume 46, Number 3 (June 2005), pp. 394–400" INTRODUCTION Aflatoxins are a major concern in poultry production because of serious economic losses. The toxicity of aflatoxins in broiler chickens has been widely investigated by determining their teratogenic, carcinogenic, mutagenic and growth inhibitory effects (Oguz and...

Introduction Antibiotics have been used for decades to improve poultry performance with low cost of implementation and ease adding to feed and water (Fernandez-Rubio et al., 2009). However, currently concern about possible antibiotic residues and resistance has arisen restrictions of antibiotics use in poultry (Jan et al., 2007; Saberfar et al., 2008). Because of this fact, industry and researchers have had to look for...

Spray-dried blood plasma is a highly digestible protein source containing immunoglobulins, growth factors, biologically active peptides, enzymes and other factors that are biologically active in the gut. Bovine SDP has been shown to produce improved growth rate, feed intake, feed efficiency and produce superior breast yield in broilers. Porcine SDP has been used in piglet starter diets to improve feed intake, growth rate and feed efficiency. There is limited...

In antibiotic-free broiler production systems, nutritionists can support the gut ecosystem with the judicious use of highly digestible diets for the young bird. Varying degrees of antibioticfree production (ABF) of chicken are now imposed by government agencies or major retailers or are being voluntarily undertaken by integrated broiler companies. ...

Use of dietary plasma in pre-starters for broilers may improve growth and health. Early nutrition of the broiler chicken is becoming more important as more knowledge is gained about the positive correlation between early growth rate and market weight and also the impact early growth and development have on the uniformity of carcass weight and composition. All of these factors become...

DDGS can be a good alternative ingredient in diets for broilers. Its use in combination with a multi-enzymatic complex, combined with an extra dose of phytase, can help to achieve optimal performance. A few trials, conducted in Argentina, are described here. Distillers Dried Grain with Solubles (DDGS) is the result of extracting ethanol from grains through...

1. Factorially designed experiments versus response surface methodology. A conventional experimental approach investigates the effects of one independent variable while keeping all other variables constant. This approach faces two challenges (i) it is only valid when the underlying principles linking cause and effect are known with some certainty; (ii) variables...

Introduction. The gastrointestinal tract (GIT) is developmentally very active in the early period posthatch in poultry species (Uni et al., 2000). The intestinal crypts that form on the day of hatch become defined in the first 48 to 96 h and continue to grow rapidly during the first 7 d (Uni et al., 2000). The intestinal villi increase significantly in diameter and length during...

I ntroduction. Between 2000 and 2010, the production of table eggs in the Dominican Republic (DR) nearly tripled, increasing from 58,000 to 150,000 tonnes (58,000,000 to 150,000,000 kg) (21) . The increase is partially due to a higher average consumption of eggs in the DR (10.3 kg per person) than the world average (8.3 kg per person). The DR also exports...

Poultry colonized with Campylobacter species are a significant source of human food-borne illness. The therapeutic use of the medium chain fatty acid caprylic acid consistently reduced enteric C. jejuni colonization in chicks by 3 to 4 logs in three separate trials. These results support caprylic acid’s potential to reduce Campylobacter carriage in poultry. Campylobacter species...

1. Introduction. Sorghum is used, either partially or entirely, as the cereal grain base in Australian pig and poultry diets but it has been associated with sub-optimal broiler growth performance (Selle et al., 2010, Liu et al., 2013). Cereal grains of different varieties and from different locations may be blended into poultry diets but varying the inclusion rate of one feed...
