1. 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

2. 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

3. 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

4. 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

5. Effects of sorghum on broilers gastrointestinal tract
This study aimed at evaluating the effects of whole and ground sorghum, compared with ground corn, on the live weight, feed conversion ratio, organs weight and intestinal biometrics and histomorphometrics. In total, 960 Hubbard Flex broilers were reared until 42-day-old and distributed into 24 pens, according to the three treatments: ground corn, whole-grain

6. Sources of trophic action on performance and intestinal morphometry of broiler chickens vaccinated against coccidiosis
The aim of this experiment was to evaluate the effect of sources of trophic action (glutamine alone, glutamine associated with glutamic acid and yeast) associated with vaccination against coccidiosis on the performance and morphometry of the small intestine of broilers. In the trial, 1,200 broiler chicks were distributed according to a completely randomized

8. Small intestine development of laying hens fed different fiber sources diets and crude protein levels
The objective of the presente study was to evaluate the effects on different dietary fiber sources and crude protein levels on the intestinal morphometry of commercial layers. Isa Brown® layers with 48 weeks of age were distributed in a completely randomized experimental design with a 3 x 2 + 1 factorial arrangement, resulting in seven treatments with seven

9. Levedura hidrolisada como fonte de nucleotídeos para leitões recém desmamados / Hidrolyzed yeast as source of nucleotides for weanling pigs
The purpose of this work was to evaluate the effects of dietary nucleotide levels on performance, organs morphometry and intestinal histology of weanling pigs. One hundred and forty-four pigs weaned at 21 days of age and 5.80 ± .16 kg initial live weight were used a completely randomized design experiment with six treatments, six replications per treatment

10. Análise histológica e morfométrica de componentes neuroendócrinos do intestino delgado do gambá Didelphis aurita (Wied-Neuwied, 1826) / Hystological analysis and morphometry of the neuroendocrine componentes of the small intestine of the opossum Didelphis aurita (Wied-Neuwied, 1826)
The objectives of this work were to aspects of the histology and morphometry of the small intestine of adult and post- puberty big-eared opossum Didelphis aurita. The morphometric description of the speciess small intestine focused on the mucous, sub-mucous and muscular layers. The entero- endocrinal-cells and the cells of the myoenteric nervous and sub-muco

11. Aditivos fitogênicos e butirato de sódio como potenciais promotores de crescimento de leitões recém-desmamados / Phytobiotic additives and sodium butyrate as potential growth promoters of weanling pigs
The antimicrobials growth promoters in the animal feed have been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate the effect of phytobiotic additives, sodium butyrate and even colistina o

12. Efeito dos prebióticos inulina HP e oligofrutose sobre a absorção intestinal de ferro e morfometria do duodeno e cólon de ratos em fase de crescimento. / Effect of the prebiotics HP inulin and oligofructose on the intestinal iron absorption and in the duodenum and colon morphometry in growing rats.
Background: Considering the prebiotic effects in the biovailability of minerals, it is important to evaluate the effect on the absorption of iron. Objectives: To evaluate the effect of HP inulin, oligofructose and synergy1, on the intestinal absorption of iron, food intake, body growth, cecal pH and weight of the intestine of rats in recovery from anemia.
