1. Intestinal morphometry and performance of broiler chickens subjected to diets with buriti oil
RESUMO Objetivou-se, com essa pesquisa, avaliar o desempenho produtivo, o rendimento de carcaça e a morfometria intestinal de frangos de corte com dietas submetidas à inclusão do óleo de buriti. Trata-se de um alimento energético que pode ser utilizado na alimentação de frangos visando substituir o óleo de soja, o qual apresenta alto custo na produç

2. Sericin as treatment of obesity: morphophysiological effects in obese mice fed with high-fat diet
RESUMO Objetivo Investigar os efeitos da sericina extraída de casulos de Bombyx mori na morfofisiologia de camundongos com obesidade induzida por dieta hiperlipídica. Métodos Camundongos machos C57Bl6, com 9 semanas de idade, foram distribuídos em Grupos Controle e Obeso, que receberam ração padrão para roedores ou dieta hiperlipídica por 10 semana

3. Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age
ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the sm

4. Xylanase for meat-type quails from 15 to 35 days old
ABSTRACT The objective of this study was to evaluate the effect of the supplementation of two xylanases in the diet of meat-type quail on performance, morphology of the intestinal mucosa, metabolization of nutrients, and carcass yield. The experimental design was a completely randomized 2×3+1 factorial arrangement [two metabolisable energy reductions (70 an

5. Digestible threonine for slow-growing broilers: performance, carcass characteristics, intestinal mucin, and duodenal morphometry
ABSTRACT Five experiments were conducted to estimate the digestible threonine requirements of slow-growing broilers: experiment 1, starter phase (days 10 to 28); experiment 2, grower I phase (days 29 to 49); experiment 3, grower II phase (days 50 to 69); experiment 4, finisher phase (days 70 to 84); and experiment 5, which was specifically conducted to deter

6. Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestina

7. Body Morphometry and Development of the Digestive System of Grey Partridge (Perdix Perdix) Depending on Age and Gender
ABSTRACT The experiment used 100 grey partridges (Perdix perdix L.), which were reared first in confinement and later in aviaries. Partridges were lighter and had greater body dimensions at 36 weeks compared to 12 weeks except for trunk length. Older birds showed greater values (p>0.05) of compactness and lower values of massiveness and long-leggedness. Sign

8. Effect of Different Dietary Threonine Levels on Optimal Growth Performance and Intestinal Morphology in 1-14 Days Old Ross 308 Broilers
SUMMARY This experiment was carried out to evaluate the effects of four levels of dietary threonine (Thr) supplementations on growth performance, gut size and histomorphometric alterations of small intestines in broiler chicks in 1-14 days. Two hundred eighty-eight Ross 308 one-day-old male broiler chicks were randomly assigned to four treatments with six re

9. Effects of glutamine on performance and intestinal mucosa morphometry of broiler chickens vaccinated against coccidiosis
ABSTRACT This study aimed to assess the effects of glutamine as feed additive on performance and intestinal mucosa morphometry of broiler chickens vaccinated against coccidiosis. A total of 400 day-old male chicks were randomly assigned to four treatments (NVNG – no vaccination, no glutamine supplementation; NVG – no vaccination, glutamine supplementatio

10. Intestinal and liver morphometry of the Yellow Tail Tetra (Astyanax altiparanae) fed with oregano oil
RESUMO O objetivo do presente estudo foi avaliar o efeito do óleo de orégano sobre a morfometria intestinal e hepática do lambari-do-rabo-amarelo, Astyanax altiparanae. Os peixes (1,46 ± 0,09 g) foram distribuídos em aquários contendo 60 L, na densidade de 0.5 peixes L-1. Foram avaliadas seis dietas práticas contendo quantidades variadas de óleo de o

11. GLUTAMIC ACID IMPROVES BODY WEIGHT GAIN AND INTESTINAL MORPHOLOGY OF BROILER CHICKENS SUBMITTED TO HEAT STRESS
ABSTRACTThe objective of this study was to evaluate the effects of 1% dietary glutamic acid on the body weight, intestinal morphometry, and anti-Newcastle antibody titers of broiler chickens submitted to heat stress. One-d-old male broiler chicks (n=120) were distributed according to a 2 x 2 factorial design with two environmental temperatures (thermoneutral

12. Post-splenectomy infections in chronic schistosomiasis as a consequence of bacterial translocation
INTRODUCTION : Bacterial translocation is the invasion of indigenous intestinal bacteria through the gut mucosa to normally sterile tissues and internal organs. Schistosomiasis may cause alterations in the immune system and damage to the intestines, portal system and mesenteric lymph nodes. This study investigated bacterial translocation and alterations in
