Effects of the Addition of Cellulase to Broiler Chicken Diets for a 21-Day Period.

The cellulose present in the cell wall of vegetables prevents the greater release of nutrients to the animal. Therefore, the use of the cellulase enzyme is a viable strategy as it is capable of breaking cellulose bonds, releasing nutrients such as glucose, increasing dietary energy, and thus improving the productive performance of birds. is efficient in the production of cellulase, which is produced via submerged fermentation followed by purification, formulation, and drying.

Enzymatic complex for broilers fed on a diet containing different levels of Distiller Dried Grains with Solubles.

The objective of this research was to evaluate the effect of the inclusion of an enzyme complex (carbohydrases, proteases and phytase) in diets formulated with DDGS inclusion levels (0 to 30%) in parameters of performance, nutrient digestibility and serum biochemical profile of broiler chickens from 1 to 42 days old. The inclusion of DDGS impaired the performance characteristics in all phases, but broilers feeding with diets containing up to 8% DDGS improves the percentage carcass. Addition of the enzyme complex improved feed conversion by 3.

Genetic parameters for tonic immobility, body weight, and morphological traits of the red-winged tinamou (Rhynchotus rufescens).

This study was carried out to estimate genetic parameters for morphology, body weight, and tonic immobility traits in the red-winged tinamou (Rhynchotus rufescens). Information on 690 birds was used and genetic parameters were estimated using Bayesian methods under a multi-trait animal model. The following traits were considered in this study: tarsal length (TL), bill length (BL), wing length (WL), head width (HW), bill width (BW), mature weight (MW), weight at 90 days (W90), and tonic immobility (TI).

Effects of processing, particle size and moisturizing of sorghum-based feeds on pellet quality and broiler production.

Objective: This study aimed to assess the effect of pelleted and expanded sorghum-based feeds prepared with different moisture levels and particle size of ingredients on metabolizable energy, ileal digestibility of amino acids and broiler performance.

Methods: The experiment was performed with 720 male broiler chicks of the Cobb strain, with treatments of six replications, with 15 birds each; they were arranged in a completely randomized design and 2×2×2 factorial scheme (pelleted or expanded feed processing, 0.8% or 1.

Using multidimensional projection techniques for reaching a high distinguishing ability in biosensing.

Recent advances in the control of molecular engineering architectures have allowed unprecedented ability of molecular recognition in biosensing, with a promising impact for clinical diagnosis and environment control. The availability of large amounts of data from electrical, optical, or electrochemical measurements requires, however, sophisticated data treatment in order to optimize sensing performance. In this study, we show how an information visualization system based on projections, referred to as Projection Explorer (PEx), can be used to achieve high performance for biosensors made with nanostructured films containing immobilized antigens.

Biosensors for efficient diagnosis of leishmaniasis: innovations in bioanalytics for a neglected disease.

The need for reliable, fast diagnostics is closely linked to the need for safe, effective treatment of the so-called "neglected" diseases. The list of diseases with no field-adapted diagnostic tools includes leishmaniasis, shigella, typhoid, and bacterial meningitis. Leishmaniasis, in particular, is a parasitic disease caused by Leishmania spp.

Use of proteoliposome as a vaccine against Trypanosoma cruzi in mice.

We have generated proteoliposomes carrying proteins of Trypanosoma cruzi for use as immunogens in BALB/c mice. T. cruzi trypomastigote and amastigote forms were sonicated and mixed with SDS, with 94% recovery of soluble proteins.

Mimetic membrane system to carry multiple antigenic proteins from Leishmania amazonensis.

Liposomes have long been used as models for lipid membranes and for the reconstitution of a single or multiple proteins. Also, liposomes have adjuvant activity in vaccines against several protozoan or bacterial organisms. Thus, the main objective of the present study was to obtain a crude extract of detergent-solubilized proteins of Leishmania amazonensis amastigotes and reconstitute them into liposomes.
