1. 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
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 die

2. Gut microflora and intestinal morphology changes of broiler chickens fed reducing dietary protein supplemented with lysine, methionine, and threonine in tropical environment
ABSTRACT This experiment aimed to discover the effect of reducing dietary protein supplemented with lysine, methionine, and threonine on growth performance, volatile fatty acid profile, and intestinal villus height and crypt depth of broilers, as well as the microflora counts isolated from broiler chicken faeces. A total of 288-day-old broilers were allocate

3. Calcium particle size and feeding time influence egg shell quality in laying hens
ABSTRACT. An experiment with Leghorn laying hens was undertaken to determine the effect of oyster shell particle size and feeding time on different production variables, calcium retention, plasma calcium content and egg internal and external quality. Two hundred Leghorn layers (40 weeks old old) were allocated in five dietary treatments with four replicates

4. Metabolizable energy and amino acid digestibility of soybean cake subjected to different dry extrusion temperatures for broilers
ABSTRACT Two experiments were conducted to evaluate the apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), and standardized ileal amino acid digestibility coefficient (SIDC) of extruded soybean cake (ESC) at four different extrusion temperatures: 90, 100, 110, and 120 °C. In experiment 1, 300 male broilers were ran

5. Effect of Non-Starch Polysaccharide (NSP) of Wheat and Barley Supplemented with Exogenous Enzyme Blend on Growth Performance, Gut Microbial, Pancreatic Enzyme Activities, Expression of Glucose Transporter (SGLT1) and Mucin Producer (MUC2) Genes of Broiler Chickens
ABSTRACT The experiment was carried out in a completely randomized design (CRD) with 625 broiler chicks (Ross 308) for 5 repetitions (25 birds per each replicated) on the 5 treatments diet. Treatments included two different types of cereal grains (wheat, and barley) with or without an enzyme supplementation along with a corn-based diet as control group. The

6. Yeast fermented additive enhances broiler growth
ABSTRACT We investigated the effects of dietary supplementations of yeast (YFA) or non-yeast fermented additives (NYFA) at 5.0 and 10 g kg−1 on the performance parameters and the size of digestive organs of broiler chickens. An isocaloric and isonitrogenous basal diet used as negative control was added with 5.0 or 10.0 g kg−1 of YFA or NYFA. Each of five

7. Physiological adaptations of ruminants and their potential relevance for production systems
ABSTRACT Herbivores face the dilemma that the level of feed intake is negatively related to factors that determine digestive efficiency, such as thoroughness of ingesta comminution by chewing, and retention of digesta in the digestive tract. Ruminants have evolved particular adaptations to solve this dilemma. Most ruminants share the characteristic of “dig

8. Breed and Sex Differences in the Gross Anatomy, Digesta pH and Histomorphology of the Gastrointestinal Tract of Gallus Gallus Domesticus
ABSTRACT A study was conducted to investigate the influence of breed and sex in the gross anatomy, digesta and histology of Ross 308 broiler and Venda chickens. Chickens were slaughtered at 90 days of age and the pH of the digestive organs was measured immediately after slaughter. The digestive organ weights and lengths of Ross 308 broiler and Venda chickens

9. Validação do Nanolipe ® como método para determinar a digestibilidade aparente dos nutrientes pelos equinos
RESUMO O NANOLIPE® é o indicador de digestibilidade LIPE® com incorporação de nano partículas que se misturam de forma mais homogênea e rápida na digesta, permitindo redução do período de adaptação e maiores taxas de recuperação daquele quando comparado com outros indicadores usados em equinos. Objetivou-se neste trabalho comparar a digestibil

10. Carcass traits and short-chain fatty acid profile in cecal digesta of piglets fed alfalfa hay and fructooligosaccharides
ABSTRACT The objective of this study was to evaluate the effects of the addition of the prebiotic fructooligosaccharide and/or alfalfa hay to piglet diets on carcass traits and short-chain fatty acid profiles in the cecal digesta. Seventy-two commercial crossbred piglets of both sexes, with an average initial weight about 6 kg and age of approximately 21 day

11. Efeito do uso de valores de tabela para enzimas degradadoras de PNA sobre o desempenho, ingestão de água, umidade da cama e viscosidade da digesta jejunal de frangos de corte alimentados com dieta à base de cevada
RESUMO. Este estudo avaliou o efeito de três valores da matriz para nutriente multi-enzimático e comparou os resultados com os obtidos com dietas baseadas em cevada e milho sem enzima. Em todo o período, a adição de todas as enzimas à dieta à base de cevada aumentou significativamente (p < 0,05) a ingestão de ração, sendo a maior ingestão observad

12. Energia metabolizável e aminoácidos digestíveis da soja integral sem ou com a suplementação de protease em rações para frangos de corte
RESUMO Foram realizados dois experimentos para determinar os valores energéticos e os coeficientes de digestibilidade ileal verdadeiros de aminoácidos de nove sojas integrais tostadas, sem ou com a adição de protease monocomponente. No primeiro experimento, para a determinação dos valores energéticos, foi utilizado o método de coleta total de excreta
