1. Co-production of Proteases and Bioactive Protein Hydrolysates from Bioprocessing of Feather Meal
Abstract: Feather meal conversion through submerged cultivations with Bacillus strains (CL33A, CL14) yielded proteases and protein hydrolysates. After 4-day (CL33A) and 10-day (CL14) cultivations, protease activities reached 461 U/mL; hydrolysates presented antioxidant (radicals-scavenging, 57-77%; Fe2+-chelation, 14-28%; Fe3+-reduction) and antidiabetic (di

2. Amino Acid Digestibility of Feed Ingredients in Cecectomized Adult Roosters
ABSTRACT A digestibility assay was conducted in order to determine the digestibility coefficients (DC) of amino acids of feed ingredients in cecectomized adult roosters. In total 48 cecectomized adult roosters were used to assess the coefficient of digestibility of 7 ingredients: corn, soybean meal, soybean concentrate, corn gluten meal, wheat bran, peanut m

3. Digestibility of animal and vegetable protein ingredients by pirarucu juveniles, Arapaima gigas
ABSTRACT The objective of this study was to determine the apparent digestibility coefficients of energy, protein, and amino acids in protein ingredients by pirarucu juveniles. A test was conducted with six protein ingredients: meat and bone meal, fish meal, hydrolyzed feather meal, poultry by-product meal, soybean meal, and corn gluten meal. Three repetition

4. Inclusion of exogenous enzymes to feathers during processing on the digestible energy content of feather meal for adult dogs
ABSTRACT This study was conducted to determine the coefficient of total tract apparent digestibility (CTTAD) of nutrients and gross energy (GE), metabolizable energy (ME), coefficient of metabolizability of gross energy (CM of GE), and fecal characteristics of dogs fed diets with two levels of feather meal, with or without addition of an enzyme blend contain

5. Effects of Diets with Graded Levels of Canola Meal on the Growth Performance, Meat Qualities, Relative Organ Weights, and Blood Characteristics of Broiler Chickens
ABSTRACT This experiment was conducted to evaluate the dietary supplementation of canola meal (CM) on the growth performance, carcass characteristics, antibody titers against Newcastle disease virus and Infectious bronchitis virus, and blood profiles of broiler chickens. In total 600 day-old feather-sexed Ross male broiler chicks were randomly assigned into

6. Atividade enzimática de lysobacter sp. isolada de penas de pinguins da Ilha de Rei George, Antártica
Keratinolitic micro-organisms are found in diverse environments, having already been described between fungi and bacteria. Among the microbial enzymes that have been gaining prominence are the keratinases, responsible for the keratin degradation. The aim of this study is to isolate and to identify micro-organisms producing keratinases from decomposing feathe

7. Apparent nutrient digestibility and mineral availability of protein-rich ingredients in extruded diets for Nile tilapia
Apparent digestibility coefficients (ADC) of gross energy and dry matter (DM) and mineral availability were evaluated for eight protein-rich ingredients (corn gluten meal, soybean meal, cottonseed meal at 280.0 and 380.0 g/kg, poultry by-product meal, meat meal, fish meal and feather meal) in compound diets for Nile tilapia. Chromic oxide was used as inert d

8. Desenvolvimento de um sistema de recirculação para estudos sobre digestibilidade em condições de alto desempenho para camarões marinhos: avaliação de ingredientes protéicos alternativos à farinha de peixe em diferentes níveis de inclus / Development of a recirculated system for digestibility studies in high performance conditions for marine shrimp: evaluation of alternative protein sources to fish meal in different dietary inclusion levels for Litopenaeus vannamei juveniles
This thesis focused on the validation of an aquaculture recirculation system (RAS) for shrimp digestibility studies and the determination of the digestibility coefficients of protein sources at different inclusion levels for shrimp feeds. The recirculation system for digestibility studies proved to be adequate for its purpose and shrimp growth rates was equa

9. Feather and blood meal in pre-starter and starter diets for broilers
Two experiments were carried out (pre-starter and starter phases) to evaluate the effect of feather and blood meal on performance, organ development and digestibility and retention of nutrients in broilers. In the first experiment, it was used 280 birds and in experiment 2, it was used 240 birds. The experimental diets were formulated with four levels of fea

10. The use of animal byproducts in broiler feeds: use of animal co-products in broilers diets
This study aimed at evaluating live performance and carcass yield of broilers fed vegetarian diets or containing different animal byproduct meals after 8 days of age. In the experiment, 1080 one-day-old male chicks were distributed in a completely randomized experimental design with 6 treatments with 6 replicates. Diets were based on corn and soybean meal, a

11. Purificação parcial e caracterização de uma protease alcalina queratinolítica de Bacillus sp. P7 / Partial purification and characterization of an alkaline keratinolytic protease from Bacillus sp. P7
Queratinases alcalinas apresentam um interessante potencial para utilização em processos de hidrólises de proteínas, particularmente na quebra de resíduos de queratina para obter produtos de melhor valor. Uma bactéria queratinolítica, previamente isolada do intestino de peixe Piaractus mesopotamicus da bacia Amazônica foi identificada como sendo Baci

12. The traceability of animal meals in layer diets as detected by stable carbon and nitrogen isotope analyses of eggs
The aim of this study was to trace the inclusion of animal meals in layer diets by analyzing eggs and their fractions (yolk and albumen) using the technique of carbon and nitrogen isotopes. Two-hundred and eighty-eight (288) 73-week-old Shaver White layers, never fed animal ingredients, were randomly distributed in six treatments with six replicates each. Th
