ABSTRACT The objective of this study was to evaluate the coefficients of total tract apparent digestibility (CTTAD) of nutrients, fecal characteristics, intestinal fermentation products, and diet palatability in dogs fed xylanase-supplemented diets with inclusion of whole or defatted corn germ in two experiments. Experiment I – six adult dogs were distributed in a 6 × 6 Latin square in a 3 × 2 factorial scheme with the experimental diets: control, without the addition of germ (CO−); CO plus xylanase (CO+); […]

ABSTRACT This study aimed to evaluate the effects of including 200 g kg −1 dried distillers grains with solubles (DDGS) to xylanase- and protease-supplemented diets for dogs on kibble properties, digestibility, fecal characteristics, and palatability. Experimental diets consisted of: 0 g kg −1 DDGS without enzymes (0WE), 0 g kg −1 DDGS with xylanase and protease (0XP), 200 g kg −1 DDGS without enzymes (200WE), 200 g kg −1 DDGS with xylanase (200X), 200 g kg −1 DDGS with protease […]

ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four treatments and six replicates. The following treatments were tested: a corn- and soybean meal-based control diet without enzymes; control diet with enzyme addition; control diet with 25% replaced […]

ABSTRACT The objective of this study was to evaluate the effect of the supplementation of two xylanases in the diet of meat-type quail on performance, morphology of the intestinal mucosa, metabolization of nutrients, and carcass yield. The experimental design was a completely randomized 2×3+1 factorial arrangement [two metabolisable energy reductions (70 and 140 kcal/kg), with or without the inclusion of two xylanases (A and B), plus a control treatment without xylanase), totalling seven treatments with five replicates and 42 quail […]

ABSTRACT The objective of this study was to evaluate levels of inclusion of an enzyme complex (EC) in corn- and soybean meal-based diets for laying hens on the digestibility of nutrients and energy. A metabolism trial was conducted using 75 Dekalb Brown laying hens at 26 weeks of age, which were distributed into five treatments with five replicates in a completely randomized design. The ingredients used in the diets received an additional (enriched) 3% methionine, lysine, cysteine, threonine, tryptophan, and […]

ABSTRACT The objective of this study was to evaluate the effect of a mixture of direct-fed microbials (DFM), yeast, and digestive enzymes on animal performance in feedlot cattle, as well as digestibility when finishing feedlot cattle. Thirty crossbreed (Charolais × Beefmaster) steers averaging 15 months old and 321.83±3.73 kg of initial body weight were used. Animals were randomly assigned to one of two treatment groups: control (basal diet) and a mixture of DFM, yeast, and digestive enzymes (basal diet + […]

ABSTRACT This study aimed to provide baseline data for the serum biochemical parameters of Brazilian sport horses undergoing physical training for eventing to be used as a practical guide. A total of 139 blood samples were collected by vacuum venipuncture of the jugular vein from healthy horses in training. Tubes without anticoagulant were used for biochemical analysis. Means and standard deviations were determined for aspartate aminotransferase (AST) (306.27±84.66 U/L), creatine kinase (CK) (181.06±80.38 U/L), urea (29.51±5.82 mg/dL), creatinine (1.44±0.20 mg/dL), […]

The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity (38% dry matter, DM). Plants were chopped approximately 2 cm after harvest and then treated with inoculants and were ensiled in 1.5-L mini laboratory silos. Two lactic acid bacterial inoculants with enzymes […]

The effects of enzyme complex SSF (solid state fermentation) on growth performance and the availability of sucrose and monosaccharides in the chyme of Nile were involved. The study included 360 fish (70g±4.43) in a completely randomized design with six dietary treatments (0, 50, 100, 150, 200 and 250 ppm of SSF) arranged in six replicates, with 10 fish per replicate. Every 15 days, one tilapia of each experimental unit was sacrificed for analyses of carbohydrate in the chyme. On day […]

The study was conducted to analyze alterations in the microbiological profile of the ileal digesta of broilers fed different levels of energy and additives. A standard diet based on corn-soybean meal and a low energy diet based on corn, soybean and wheat bran were prepared. Either Enterococus faecium probiotic or xylanase, amylase plus β-glucanase enzymes or the mix of probiotic and exzymes were added or not to each energy level, resulting in eight treatments. Birds were distributed in a 2 […]
