title: Effect of Exogenous Protease, Mannanase, and Xylanase Supplementation in Corn and High Protein Corn DDGS Based Diets on Growth Performance, Intestinal Morphology and Nutrient Digestibility in Broiler Chickens

description: ABSTRACT A study was conducted to evaluate the effects of exogenous enzymes supplementation in high protein (Hi-Pro) corn DDGS-based diets on broiler growth performance, intestinal health, and nutrient digestibility. A total of 200 one-day-old broiler chicks were randomly allocated to four dietary treatments with five replicates of 10 birds each. A basal diet (CON) was formulated (CP: 20%; ME: 2900 Kcal/kg) containing 15% of dietary crude protein share from Hi-Pro corn DDGS. Three experimental diets were developed using basal diets; diet one was supplemented with protease (CON-P), diet two with an enzyme mix of mannanase and xylanase (CON-MX) and diet three with a protease and enzyme mix of mannanase and xylanase. A digestibility assay was carried out using Celite (insoluble acid ash), from day 29 to day 35. On day 35, four birds from each replicate were picked randomly and killed by cervical dislocation to collect ileal digesta. In addition, duodenum, jejunum and ileum lengths were measured, and tissue samples were collected from midpoints of jejunum to note villus height and crypt depths. Feed intake, body weight gain and feed conversion ratio were not affected by dietary treatments during the entire study period (p&gt;0.05). Likewise, no difference in carcass characteristics, soft organ weight, intestinal morphology, apparent amino acids digestibility and visible ileal digestible energy was observed by the dietary treatments (p&gt;0.05).Supplementation of exogenous protease and enzyme mix (mannanase and xylanase) had no effect on growth performance, intestinal integrity and nutrient availability of broiler chickens fed Hi-Pro DDGS-based diets.

title: Influence of Artemisia Annua on Broiler Performance and Intestinal Microflora

description: ABSTRACT The present study aimed to investigate the effect of Artemisia (Artemisia annua) supplementation as essential oil and powder, in broiler diet on performance and intestinal microflora. One hundred and eighty Cobb 500 broiler chicks assigned to three experimental groups (six replicates with 10 broilers per replicate) were housed in an environment-controlled house. Compared to the control diet, the experimental diets included 0.05 g kg-1 Artemisia essential oil (E1), 0.05 g kg-1 essential oil plus 0.1 g kg-1 powder of Artemisia (E2), respectively. Growth performance was monitored throughout days 14-42. Artemisia supplementation (E1, E2) did not influence growth performance of the chicks. Compared to the C and E1, the chicks from E2 group had a lower count of Enterobacteriaceae in the intestinal and caecal content, both at 35 and at 42 days. The Artemisia supplements did not influence the staphylococci populations from the intestinal content of the chicks (42 days), but in the caecal content samples, this count was lower in E2 (8.836 log10 cfu g-1) than in C (8.876 log10 cfu g-1) and E1 (8.870 log10 cfu g-1). The count of lactobacilli increased in the intestinal and caecal contents of chickens fed the diet supplemented with Artemisia at the 35th and 42nd day. Diet supplementation with A. annua essential oil and powder could be an effective solution in maintaining the proper microflora balance in the chicks’ intestine.

title: Requirement of Digestible Methionine + Cystine to Molted Laying Hens

description: ABSTRACT The present study aimed to determine the ideal requirement of digestible methionine + cystine to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. 144 Hisex White laying hens with 84 weeks-of-age were used. The experimental design was completely randomized with treatments constituted for six levels of digestible methionine + cystine (0.45, 0.50, 0.55, 0.60, 0.65, and 0.70%) in the diets, with four replicates of six birds each. Data collected were evaluated by polynomial regression at 5%. There was a significant effect (p&lt;0.05) of digestible methionine + cystine on feed intake, energy intake, protein intake, egg production, and egg mass. Internal egg quality presented positive linear effect (p&lt;0.05) on albumen height and yolk color. External egg quality was affected (p&lt;0.05) in eggshell %, eggshell thickness and eggshell resistance, where the level of 0.60% of digestible methionine + cystine in the diets provided eggshells with better quality (higher percentage, thicker and breaking resistance). Differences (p&lt;0.05) were also observed in glucose and triglycerides concentration, with 0.60% of digestible methionine + cystine in the diets presenting better equilibrium. Results of the present study suggested that higher levels of digestible methionine + cystine improved the performance and internal egg quality of molted laying hens. The level of 0.60% of digestible methionine + cystine provided better eggshell and equilibrium on blood biochemistry.

title: Isolation and functional caharacterization of chia (Salvia hispanica) proteins

description: Abstract The objective was to isolate and characterize the proteins of chia seeds cultivated in the Mexican southeast. The main protein fraction was glutelins (42.94%) that had the highest Water Absorption Capacity (WAbC). Prolamins had the highest Water Adsorption Capacity (WAdC) (1.83 g/g). Glutelins registered the highest Water Holding Capacity (WHC). A higher Oil Holding Capacity (OHC) of chia protein fractions was registered in globulins and a higher Organic Molecule Absorption Capacity (OMAbC) was registered in albumin fractions (5.5 g/g of sample). At pH 2, 4 and 6, the glutelins registered a higher Emulsifying Capacity (EC) while, at pH 8 and 10, the prolamins recorded a higher EC percentage. Chia fractions registered the highest Foam Capacity (FC) values at pH 8 for globulins and pH 2 for albumins, prolamins and glutelins. Foaming and emulsifying stability (FS and ES) was greatly influenced by pH.

title: Estimation of soil phosphorus availability via visible and near-infrared spectroscopy

description: ABSTRACT: Spectroscopic techniques have great potential to evaluate soil properties. However, there are still questions regarding the applicability of spectroscopy to analyze soil phosphorous (P) availability, especially in tropical soils with low nutrient contents. Therefore, this study evaluated the possibility to estimate P availability in soil and its pools (labile, moderately labile and non-labile) via Vis-NIR spectroscopy based on intra-field calibration. We used soils from two different locations, a plot experiment that received application of phosphate fertilizers (Field-A) and a cultivated field where a grid soil sampling was performed (Field-B). We used the technique of diffuse reflectance in the visible and near-infrared (Vis-NIR) to obtain the spectra of soil samples. Predictive modeling for P availability and labile, moderately labile and non-labile pools of P in soil were obtained via partial least squares (PLS) regression; classification modeling was performed via Soft Independent Modeling of Class Analogy (SIMCA) on three P availability levels in order to overcome the limitation on quantifying P via Vis-NIR spectroscopy. We found that isolating P contents as the only variable (Field-A), Vis-NIR spectroscopy does not allow estimating P pools in the soil. In addition, quantification of P available in the soil via predictive modeling has limitations in tropical soils. On the other hand, estimating P content in soil through classes of availability is a feasible and promising alternative.

title: Co-inoculation with Azospirillum brasilense in soybean cultivars subjected to water déficit

description: ABSTRACT This study aimed to verify the effect of co-inoculation, association between Azospirillum brasilense and Bradyrhizobium japonicum bacteria, on soybean plants subjected to water deficit at two sowing dates. Two field experiments were conducted at the Universidade Federal de Tocantins, campus of Palmas, Brazil, in 2016. The experimental design was randomized blocks in a split-split-plot arrangement with four repetitions, where the plots consisted of two irrigation depths (100 and 25% of crop evapotranspiration - ETc), the subplots was composed of two methods of inoculant application (inoculation with Bradyrhizobium japonicum and co-inoculation with Azospirillum brasilense + Bradyrhizobium japonicum) and the sub-subplots comprised two soybean cultivars (TMG 132 and ANTA 82). The cultivars responded differently to the sowing dates. Co-inoculation did not influence grain yield under full irrigation conditions (100% ETc), in neither cultivar evaluated. However, under the water deficit condition (25% ETc), the grain yield of the cultivar TMG 132 increased 77.20%, indicating that there are different responses of interaction between Azospirillum brasilense, plant genotype and sowing dates.

title: Physiological and vegetative behavior of banana cultivars under irrigation water salinity

description: ABSTRACT The purpose of the study was to evaluate the effect of salinity levels of irrigation water on physiology and growth of banana cultivars during the vegetative stage. The experiment was carried out following a completely randomized design in split plots, with four levels of salinity in irrigation water (0.5, 2.0, 3.0 and 4.0 dS m-1) and four banana cultivars (Pacovan, Prata Anã, BRS Platina and Princesa) with three repetitions. Stomatal conductance, transpiration, relative water content, leaf water potential and proline concentration were evaluated at 150 days after transplanting (DAT), besides plant height, stem diameter and leaf area. All variables showed sensitivity to the increase of salinity level of irrigation water. The results of soil water extraction, relative water content in leaf (RWC), leaf water potential and proline content differed (p ≤ 0.05) among the cultivars. Prata Anã and BRS Platina cultivars were the ones with lowest sensitivity, while Pacovan and BRS Princesa cultivars showed larger variation of soil water extraction and RWC with the increase in irrigation water salinity (electrical conductivity), being considered the ones of highest sensitivity to salinity in this study. Banana crop growth as a consequence of physiological effects was inhibited by the increase in water salinity, mainly in “BRS Princesa” cultivar.
