The trial was conducted to evaluate the performance and morphologic changes of gastrointestinal tract and economic analysis for broilers fed sorghum-soybean meal-based diets, supplemented or not with multienzymatic complex (xilanase, amylase, protease), in the starting (experiment I) and finishing (experiment II) phases. The experiment was analyzed as a randomized block design with a 3 x 2 factorial arrangement [three sorghum levels (0, 50, and 100%) x enzyme level (0 and 100%)]. The experimental unit was a box with 17 birds […]

One experiment was conducted to evaluate the effect of the addition of multienzymatic complex in diets with different quality of extruded full fat soybeans on the performance of broiler chicks. A total of 960 Avian Farms male broiler chicks were used from 1 to 21 days of age. The completely randomized experimental design utilized a 3 x 2 factorial treatment structure with three extruded full fat soybeans (under, standard and over processed) and two levels of multienzymatic complex addition (0.0 […]

The present trial aimed to evaluate the effects of wilting (wet vs. wilted), particle size reduction (small vs. large) and the addition of fibrolytic enzymes (alone vs. combined with Lactobacillus plantarum) on the chemical composition and effluent yield of Tanzaniagrass silages (Panicum maximum Jacq. cv. Tanzania). The forage was harvested and cut at 45-day vegetative re-growth period and stored in the experimental plastic silos (50 L) during 136 days. During the storage period, the effluent flow was collected and measured […]

The objective of this trial was to evaluate the effect of the harvest time (45 or 60 days of regrowth), and enzymatic-bacterial inoculants on the fermentation characteristics, chemical composition, in vitro dry matter digestibility (IVDMD) of silages from Tanzânia and Mombaça (Panicum maximum Jacq.) cultivars. Forages, cut in the different ages, were ensiled according two treatments: A – Control; B – Ensiled with enzymatic-bacterial inoculants. A completely randomized experimental design was in a 2 x 2 x 2 factorial arrangement […]

Two experimental assays were carried out to evaluate the effect of the soybean oil and enzymatic complex addition in corn and soybean meal based diets on the broilers performance and nutrients digestibility. In the experiment 1, 960 broiler chickens, unsexed, received the treatments into 4 x 2 factorial scheme (four levels of soybean oil addition, 0; 2.5; 5.0 and 7.5%, with or without addition of a enzymatic complex with amylase, xylanase and protease) in four replicates of 30 chickens each, […]

Two assays were carried out to evaluate the broilers performance, nutrients digestibility and the energy values of diets formulated with corn from different varieties (Experiment 1) and regions (Experiment 2), supplemented with an enzymatic complex. In each assay, were used 480 male broilers Hubbard, 14 days old, grown from 14 to 27 days to evaluate performance. The broiler chickens fed an experimental diets in 6×2 factorial design (varieties x region), in four replicates of 10 broilers in each experimental unit. […]

This study was run to evaluate the effect of inclusion of an enzymatic cocktail, containing proteases, amilases and cellulases (Vegpro) in broiler diets. The cocktail was added with the ration of 1 kg per 200 kg of soybean meal. Two thousand and forty female Ross chicks were distributed in eight treatments with seven replicates each. A split-plot experimental design was used. Treatments consisted of T1 ¾ control (no enzyme added), T2 ¾ diet five percent lower in energy, protein and […]

Three experiments were carried out to study the performance and digestibility of nutrients and to determine the endogenous enzyme level in grouving swines fed diets supplemented with exogenous enzymes. The experimental diets consisted of corn, soybean meal, vitamins and minerals plus the addition of exogenous enzymes. The mixtures consisted of 25 g of exogenous enzyme per 100 kg of diet. The basic composition of the diets were 18.00% of crude protein (CP) and 3400 kcal/kg of digestible energy (DE). In […]

A 40 days alfalfa (Medicago sativa) regrowth was harvested in the summer at the early flowering stage with (26.3% DM, 18.94% CP, 8,90% DM soluble carbohydrates and 43.35 meq OH–/100 g DM buffering capacity). Part of the material was direct cut ensiled (26.3% DM) and part was wilted for 20 hours (44.12% DM). Both silages, either wilted or not, were assigned to four treatments: Control, Enzymes, Inoculate and Inoculate plus Enzymes and were ensiled in laboratory silos (3.6 L), with […]
