This research evaluated a feed additive (benzoic acid, eugenol, thymol, and piperine), associated or not with colistin, in weaned piglets feeding. The parameters were growth performance, apparent total tract digestibility (ATTD) of nutrients, diarrhea incidence, intestinal morphology, relative weights digestive organs, microbial diversity, the percentages operational taxonomic units microorganisms cecum content pigs. One-hundred eight crossbred (5.3 ± 0.5 kg) used three-phase feeding program...

ABSTRACT Organic acids are used as feed additives to promote growth of weaned piglets since they prevent the occurrence diarrhea. Thus, performance and digestibility assays were conducted economic viability diets was evaluated. In assays, 64 hybrid with a mean weight 5.87±0.31kg divided in randomized block design consisting 4 treatments, 8 repetitions 2 per experimental unit (1 castrated male 1 female). assay, 24 8.21±0.79kg individually assigned treatments 6 repetitions. The two follows:...

In the way to reduce costs in poultry production, high densities of birds are adopted production systems. Such can lead an inappropriate environment, compromising welfare and decreasing animal performance. this work we aimed evaluate effects different on productive yield, egg quality immunological aspects Japanese quails. It was used 816 quails, during phase, a random design, with four treatments (121.43 cm2/bird; 106.25 94.44 cm2/bird 85.00 cm2/bird) six repetitions each. Results indicate...

Objetivou-se no presente estudo avaliar a qualidade interna de ovos brancos e vermelhos, comercializados durante o inverno verão, estado São Paulo. Para tal análise, utilizaram-se classificados como tamanho grande, avaliação da realizada por meio das seguintes variáveis: massa média do ovo, gravidade específica, unidade Haugh, índice gema, coloração gema incidência partículas estranhas nos ovos. O delineamento experimental foi inteiramente ao acaso, em fatorial 2 x (cor casca épocas ano),...

This study was developed to evaluate the effect of adding natural pigments on storage eggs from laying hens in second production cycle submitted diets based corn and low-tannin sorghum. A total 160 Hy-Line Brown at 90 - weeks old after forced molting were used. The evaluated isolated interaction two factors: inclusion (control diet 50% sorghum replacing corn; RC 2% powdered dry turmeric rhizome; PU annatto powder; RCPU 1% rhizome + powder) combined with period (0, 3, 7, 14 21 days). studied...

This study aimed at evaluating the effect of dietary calcium levels and replacement sources with different particle size compositions on performance egg quality brown layers in their second production cycle. A randomized block experimental design was applied 12 treatments a 3x4 factorial arrangement: three (2.6, 3.2, 3.8 %) four combinations (1- 100% fine limestone (FL), 2- 50% FL + coarse (CL), 3- oyster shell (OS), 4- 25% CL+ 25 %OS), six replicates eight birds each. Calcium were analyzed...

The objective of this study was to evaluate the effects addition prebiotic fructooligosaccharide and/or alfalfa hay piglet diets on carcass traits and short-chain fatty acid profiles in cecal digesta. Seventy-two commercial crossbred piglets both sexes, with an average initial weight about 6 kg age approximately 21 days, were distributed a randomized block design, using factorial scheme, which consisted three levels (0, 5, 10%) two (0 0.3%). Fiber presence exerted effect digesta acid,...

ABSTRACT The objective of this study was to evaluate the use an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in feed swine in growing finishing phases, by assessing their performance (daily weight gain, daily intake, conversion), dry matter, crude protein, energy apparent digestibility, costs. Eighty pigs-castrated males, females-of approximately 63 days age initial 20.18±1.98 kg were distributed a 5×2 factorial arrangement (diet × sex), randomized block...

The objective of this review aspects concerned with the natural behavior birds, stress suffered when subjected to confinement, importance study mineral bone density and understanding causes osteoporosis appropriate measures be taken mitigate severity disease contribute animal welfare. Therefore, research in area mineralization, adaptations environment diets adequate levels calcium, vitamin D phosphorus for maintenance quality tissue birds is seen.

Bovine meat and bone meal (MBM) has been used as a low-cost protein source in corn- soybean meal-based poultry diets. However, to date, no studies investigating the effect of dietary inclusion MBM on performance Japanese quails egg production costs were found literature. In this study, 600 lay distributed completely randomized experimental design consisting six treatments (replacement levels by MBM:0, 1, 2, 3, 4, 5%) with five replicates 20 birds each investigate if is viable alternative...

Palm heart processing generates a large amount of residues like leaves, sheath and stems that have potential for ruminant feeding. This study aimed to evaluate the effect in natura peach palm (Bactris gasipaes Khunt.) on performance, dry matter (DM) digestibility intake ruminants. External was most suitable residue sheep, cattle buffaloes feeding, although sheep presented rejection 43.5 g kg-1. Thereby, assays apparent vitro were done under four feeding treatments, which exclusive sheath,...
