The aim was to evaluate the effects of yeast probiotic on diet digestibility, fermentative metabolites, and fecal microbiota dogs submitted dietary change. Sixteen were divided into two groups eight each: control, without, with probiotic, receiving 0.12 g/dog/day live Saccharomyces cerevisiae yeast. fed a lower protein fiber for 21 days then changed higher until day 49. Yeast supplementation did not statistically influence digestibility. group had concentration total biogenic amines (days...

An experiment was carried out to evaluate the digestibility and metabolizability of corn a corn/soy-based diet with inclusion or not xylanase and/or phytase in broilers. In trial, 1,120 broiler chicks were distributed according completely randomized experimental design, consisting 16 treatments, 10 replicates 7 birds each. Treatments evaluated following factorial arrangement (4 × 2 2), 4 levels (zero, 50, 100, 150 fungal β-xylanase units/kg; FXU), (zero 1,000 FTU), diets (corn/soy pure...

Direct-fed microbials (DFM), such as Bacillus subtilis and licheniformis, may improve gut functionality of the host by favouring non-pathogenic bacteria reducing formation putrefactive compounds. The aim this study was to assess nutrient digestibility, faecal characteristics intestinal-fermentation products in dogs fed diets with licheniformis. Sixteen were randomly divided into two groups. Every eight control diet or addition 62.5 g DFM (B. B. licheniformis)/ton. Diets provided throughout a...

Feed additives, such as prebiotics and essential oils, are used in pet foods can affect digestibility, palatability, intestinal functionality of dogs. The combined effects yeast cell wall oregano oil on apparent total tract digestibility (ATTD) palatability diet, fermentation products, fecal microbiota dogs were analyzed. Eighteen adult fed for 20 days with three dry extruded diets dogs: control (without the additive), a diet containing 1.5 kg/ton (1.5YCO), 3.0 (3.0YCO). inclusion both...

Considering the benefice demonstrated by modulating action of probiotics on host intestinal microbiota, this study aimed to evaluate diet digestibility and fecal characteristics dogs fed with diets supplemented Bacillus subtilis (C-3102). Twelve young Beagle were distributed in a completely randomized experimental design consisting two treatments: no addition or 0.01% Dogs passed through 25 days adaptation diets, five total feces collection. The following evaluated: pH, score (1 - watery...

The objective of this study was to evaluate the apparent total tract digestibility (ATTD), ME, and fecal characteristics adult dogs puppies fed raw soybeans (RSB) their by-products. Six treatments were evaluated: 1 reference diet (REF), based on a maize-poultry by-product meal, 5 extruded diets containing 70% ingredients REF 30% soybean processed product [defatted meal (DSM), micronized (MSB), (SBM), RSB, or toasted (TSB)]. (5.8 yr old) 6 (5.1 mo used in with double Latin square design (6 ×...

The objective of this study was to evaluate the effects microalgae Schizochytrium sp., as a dietary source docosahexaenoic acid (DHA), on diet palatability, coefficients total tract apparent digestibility (CTTAD) nutrients and metabolizable energy (ME), blood variables indicators immunity in dogs. We also evaluated oxidative stability. Two diets containing 0 0.4% sp. were three experiments. On Experiment I palatability 0% versus compared. In II test offered for 30 days determine...

This study aimed to evaluate the effects of yeast extract on apparent total tract digestibility (ATTD) nutrients, metabolisable energy (ME), and palatability diet, intestinal fermentative products in dogs. In addition, we also evaluated ATTD ME Four diets containing 0, 40, 80, 120 g/kg were evaluated. Diet digestibility, faecal characteristics, 12 adult Beagle dogs distributed a randomised block design, with two periods 10 days each. Yeast was obtained by regression analysis. Sixteen used...

This study aimed to evaluate the effects of including 200 g kg −1 dried distillers grains with solubles (DDGS) xylanase- and protease-supplemented diets for dogs on kibble properties, digestibility, fecal characteristics, palatability. Experimental consisted of: 0 DDGS without enzymes (0WE), xylanase protease (0XP), (200WE), (200X), (200P), (200XP). Kibbles were evaluated density, extruded size, expansion index, hardness, uniformity. Six beagle distributed in a 6×6 Latin square design...

Starch is the main energy source in broiler diets. However, endogenous amylase secretion young broilers suboptimal to completely digest dietary starch, so exogenous α-amylase supplementation may help increase starch digestibility. The objective of this study was assess increasing doses an (0, 40, 80, 120, and 160 kilo-novo units (KNU)/kg) on corn a complete corn-soybean meal diet for 25-day-old broilers. Jejunal ileal apparent digestibility coefficients available resistant total DM, DM tract...

As vitaminas são micronutrientes que participam de inúmeros processos metabólicos do organismo, sendo, portanto, essenciais para ótima saúde e desempenho animal. Poucos trabalhos foram realizados nos últimos anos estimar os melhores níveis frangos, havendo grande variação entre empregados comercialmente. Sendo assim, o objetivo deste trabalho é apresentar conceitos atuais na avaliação das exigências frangos sugeridos pela indústria pelo meio científico. A maioria dos recomendados NRC (1994)...

The objective was to evaluate kibble characteristics, coefficients of total tract apparent digestibility (CTTAD) nutrients, metabolisable energy (ME), palatability, and faecal characteristics diets containing potato starch (PS) fed adult dogs puppies. Four 0, 100, 200, or 300 g/kg PS, at the expense corn, were evaluated in three experiments. Experiment 1 physical diets. 2 diet eight (7 years old) puppies (6 months according a double 4 × Latin square design. 3 palatability (0 vs. 100 PS 0...

This research aimed to evaluate the apparent total tract digestibility (ATTD) of nutrients, metabolisable energy (ME) and palatability diet, as well products intestinal fermentation faecal microbiota dogs fed with dried apple. For this purpose, three experiments were performed. In Experiment I, ME four diets containing 0%, 3%, 6% 9% apple evaluated, in addition characteristics dogs. The offered eight adult dogs, distributed double Latin square (4 × 4), totalling repetitions per treatment....

The consumption of readily digestible starch sources, such as corn, can negatively impact endocrine disorders related to hyperglycaemia in predisposing animals. In this sense, sources containing slowly and resistant fractions assist glycemic control. present study analyzed the postprandial response blood variables rats fed with four extruded diets brown rice, sweet potato pea main source. Thirty-two male Wistar (90 days old) were divided into groups eight animals each. received one...

This experiment aimed at evaluating the effects of including enzyme, β-mannanase, in dog (Canis lupus familiaris) diets based on either poultry (Gallus gallus domesticus) by-product meal (PBM) or soybean [Glycine max (L.) Merr.] Meal (SBM). The second objective was to evaluate 3 methods for determining energy and nutrient digestibility values fed dogs: total fecal collection (TFC) use aia crude fiber (CF) as a marker. Eight dogs were allotted replicated latin square (4 by 4) design. There 2...
