Suplementação de acidificantes orgânicos e inorgânicos em dietas para frangos de corte: desempenho zootécnico e morfologia intestinal

Abstract: RESUMO -Avaliou-se o efeito da suplementação de acidificantes na dieta sobre o desempenho zootécnico e a morfologia intestinal de frangos de corte. Foram utilizadas 2.112 aves distribuídas em oito tratamentos, em seis repetições, constituídos da adição de antibióticos ou de misturas de acidificantes, de acordo com a fase de desenvolvimento (1 a 7, de 8 a 21 e de 22 a 35 dias de idade), em diferentes composições: controle positivo = bacitracina metil dissilicato (BMD -55 ppm) + colistina (10 ppm); controle nega… Show more

“…In the evaluation of the activity of organic acids on broiler performance, Skinner et al (1991) found a positive effect of the fumaric acid (0.125%) until 49 days of age with linear reduction of mortality until 0.5% of the diet. Viola & Vieira (2007) tested different mixtures of organic acids in diets and verified that the body weight gain was not affected by treatments.…”

“…The later concluded that organic acids showed variable effects on the performance of broilers. With the same purpose, researchers (Viola and Vieira, 2007) have reported the beneficial effects of organic acids such as CA as alternatives to some feed additives and antibiotics on performance and carcass quality of broilers. Similar results with present study were found by Ebrahimnezhad et al (2008) and Nourmohammadi et al (2010) indicating that addition of CA caused significant increase in carcass yield of broiler chickens.…”

“…The pH of the digestive tract of piglets is high at this stage and the production of hydrochloric acid and digestive enzymes is insufficient (Tsiloyiannis et al, 2001). Digestion is further compromised by the administration of complex diets with a high protein content (Chiquieri, 2009), a fact favoring the proliferation of pathogenic microorganisms and development of intestinal disorders (Viola and Vieira, 2007;Bocklor et al, 2007). All of these factors contribute to the occurrence of post-weaning diarrhea, which can lead to the death of the animal or significant weight loss during subsequent phases (Corassa et al, 2006;Sanches et al, 2006).…”
