1. Extended-Spectrum Beta-Lactamase Producing Strains of Escherichia Coli Isolated from Avian Cellulitis Lesions
ABSTRACT Avian cellulitis causes significant losses to the poultry industry. Avian-pathogenic Escherichia coli (APEC) is the etiological agent of that disease. This microorganism has zoonotic potential and may act as reservoir of antimicrobial-resistance genes. In this context, the production of extended-spectrum B-lactamase (ESBL) is one of the main antimic

2. Extended Spectrum Beta-Lactamase Production and Biofilm Formation in Salmonella Serovars Resistant to Antimicrobial Agents
ABSTRACT Antimicrobial resistance is a serious public health problem and Salmonella spp. is highly resistant to antimicrobial agents. Biofilms are important in the food industry due to their formation on products, utensils, and surfaces and the difficulty in their removal. The objective of this study was to assess extended spectrum beta-lactamase (ESBL) prod

3. Antioxidant Activities of Chicken Egg White Hydrolysates Obtained by New Purified Protease of Aspergillus avenaceus URM 6706
Abstract Protein hydrolysates originating from egg white have already been reported to be bioactive and, among their biological activities, possess the antioxidant property that protects the body from early ageing and diseases linked to oxidation. Therefore, the objective of this work was to evaluate the antioxidant activity of hydrolysates obtained by the

4. The Role of ß-Mannanase (Hemicell) in Improving Poultry Productivity, Health and Environment
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nu

5. PRODUCTION OF METHYL ESTERS BY ENZYMATIC HYDROESTERIFICATION OF CHICKEN FAT INDUSTRIAL RESIDUE
Abstract The feedstock cost can comprise more than 75% of the overall biodiesel cost, and then economic issues are the main limitations of biodiesel production. This research focused on the use of alternative feedstock and production processes. The production of fatty acid esters from residues becomes an interesting alternative route since it is possible to

6. Synanthropic diptera affecting layer poultry farms: a review
RESUMO: A avicultura de postura é uma atividade econômica de grande relevância para o Brasil. Aspectos sanitários dos plantéis de galinhas poedeiras, tais como infestações por parasitos e pragas avícolas, influenciam significativamente os indicadores de produtividade desse setor. Nesse contexto, o controle de dípteros sinantrópicos constitui um dos

7. Optimization of solid-state fermentation conditions of Bacillus licheniformis and its effects on Clostridium perfringens-induced necrotic enteritis in broilers
ABSTRACT In the present study, we examined the growth parameters of Bacillus licheniformis in solid-state fermentation (SSF) and evaluated the effects of Bacillus licheniformis-fermented products on Clostridium perfringens-challenged broilers. During four and six days of SSF, the highest viable biomass was observed at 5% glucose, 10% soybean meal, 3% yeast,

8. Water absorption process capability analysis by chicken carcasses during precooling
Abstract Cooling of carcasses using water immersion is the most used process in the poultry industry. In this stage, besides the reduction of temperature, water absorption in the carcasses occurs and, consequently, in the chicken cuts, which are monitored by the companies and supervised by the Ministry of Agriculture, Livestock, and Supply of Brazil, which

9. Knowledge and attitudes of official inspectors at slaughterhouses in southern Brazil regarding animal welfare
ABSTRACT We assessed the views, knowledge, and attitudes of livestock inspectors working in federally inspected slaughterhouses in southern Brazil, the major pig and poultry processors in the country, regarding farm animal behavior and welfare, and factors that may influence animal welfare improvements at abattoirs. An online questionnaire with closed and op

10. Inactivation of phoPQ genes attenuates Salmonella Gallinarum biovar Gallinarum to susceptible chickens
Abstract Salmonella Gallinarum is a host-restrict pathogen that causes fowl typhoid, a severe systemic disease that is one of the major concerns to the poultry industry worldwide. When infecting the bird, SG makes use of evasion mechanisms to survive and to replicate within macrophages. In this context, phoPQ genes encode a two-component regulatory system (P

11. Modulation of Physiologic Parameters in Molted Isa Brown Laying-Hens by Glutamine + Glutamic Acid Supplementation
ABSTRACT Feed costs are the main limiting factors in poultry industry and alternative sources of food and/or feed supplements to optimize the bird´s life cycle and to extend their production period need to be explored. This study evaluated morphometric parameters of the small intestine and gonadotropin transcript levels in Isa Brown laying hens supplemented

12. Phylogenetic and Pathotypic Characterization of a Newcastle Disease Virus Strain Isolated from Ducks and Pigeons in Hubei, China
ABSTRACT Newcastle disease is a highly contagious disease responsible for major outbreaks and considerable economic losses in the poultry industry in China. There is still little information available regarding gene characterization of the NDV, especially in ducks and pigeons. Therefore, the aim of this study was to investigate NDV isolated from ducks and pi
