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. Identification and Characterisation of Alternative Splice Variants of Hoxb9 and Their Correlation with Melanogenesis in the Black-Boned Chicken
ABSTRACT Homeobox B9 (HOXB9) gene has been demonstrated to be associated with melanogenesis in chicken plumage by high-throughput RNA sequencing. In this study, we cloned and characterised HOXB9 in black-boned chickens. Two alternative splice variants (HOXB9-1 and HOXB9-2) were identified in chicken feather bulbs. Expression analysis of HOXB9 in 11 differen

4. Procedures for central auditory processing screening in schoolchildren
Resumo Introdução: A triagem do processamento auditivo central em escolares tem suscitado discussões na literatura, tanto em relação ao protocolo a ser usado quanto à importância de ações voltadas para a prevenção e promoção da saúde auditiva. Um desafio na audiologia é definir procedimentos eficazes na triagem do processamento auditivo centr

5. Effect of Hatching Time on Yolk Sac Percentage and Broiler Live Performance
ABSTRACT This study investigated the effects of broiler chick hatching time on the percentage of the yolk sac and subsequent broiler live performance. Broiler hatching eggs were obtained from a commercial flock at 55 wk of age and were stored for 2 d at 18°C and 75% relative humidity (RH) prior to incubation. Chicks were identified as hatching Early (471-47

6. Differentiation of free-ranging chicken using discriminant analysis of phenotypic traits
ABSTRACT In this study, we investigated the differentiation of five different chicken ecotypes - Center, North, South, West, and East - of Saudi Arabia using discriminate analysis. The analysis was based on nine important morphological and phenotypic traits: body color, beak color, earlobe color, eye color, shank color, comb color, comb type, comb size, and

7. Usability of CART algorithm for determining egg quality characteristics influencing fertility in the eggs of Japanese quail
ABSTRACT The objective of this study was to determine the effects of egg quality characteristics (egg weight, egg width, egg height, and shape index) on fertility of eggs of Japanese quail with different colored feathers (yellow, white, grizzled, and normal), which are of economic importance for poultry production. For this purpose, 383 eggs of Japanese quai

8. 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

9. SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL
ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few s

10. 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

11. 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

12. Molecular Diagnosis of Beak and Feather Disease in Native Brazilian Psittacines
ABSTRACT The incidence of the psittacine beak and feather disease virus (BFDV) was investigated in Brazilian native parrots with normal feathering arriving at rescue and triage centers for wild animals (CETAS, IBAMA) in the state of Minas Gerais, Brazil. BFDV DNA was investigated by previously described PCR technique for the partial amplification of BFDV ORF
