The objective of this work was to evaluate the performance and intestinal histomorphometry of small intestine segments in broiler chickens in 1 to 21-day of age period, fed diets with different growth promoter additives: control diet (without growth promoter); control diet + antibiotic (colistin and zinc bacitracin); control diet + probiotic (Protexin); control diet + prebiotic (Bio moss); control diet + probiotic + prebiotic. The birds were distributed in a random block design, with five treatments and four replications. It […]

The objective of this study was to evaluate the effect of adding antibiotics, probiotics, prebiotics, symbiotic and sodium gluconate for swine from 28 to 142 days of age, corresponding to the nursery, growing and finishing phases. One hundred and sixty-eight piglets were used weaned at 21 days in a randomized complete design in 42 pens with four male piglets in each experimental unit with six replications and seven treatments: control basal feed; basal feed + antibiotic; basal feed + probiotic; […]

An experiment was conducted with 2,112 Ross male broiler chicks, with the objective to evaluate the use of non-nutrient additives (antibiotic, prebiotic and symbiotic) on performance and carcass characteristics of broilers. The birds were distributed in a complete randomized design in 2 × 6 (corn × additive) factorial arrangement, with 12 rations, eight replicates and 22 birds per experimental unit. Diets were based on corn and soybean meal, using in the half the rations standard quality corn (Rations 1 to […]
