Selenium and/or vitamin E upregulate the antioxidant gene expression and parameters in broilers.

Background: In contrast to free radicals, the first line of protection is assumed to be vitamin E and selenium. The present protocol was designed to assess the roles of vitamin E and/or a selenium-rich diet that affected the blood iron and copper concentrations, liver tissue antioxidant and lipid peroxidation, and gene expression linked to antioxidants in the liver tissue of broilers. The young birds were classified according to the dietary supplement into four groups; control, vitamin E (100 mg Vitamin/kg diet), selenium (0.

Prosthetic polyester-based hybrid mesh for repairing of perineal hernia in dogs.

Background: This study involves the use of a new multifunctional prosthetic mesh for treatment of the perineal hernia without complications. The prosthetic mesh is a hybrid platform of both synthetic and natural materials, mainly consisting of a synthetic commercial polyester fabric (CPF) to deliver the required mechanical integrity. The CPF mesh was coated by a natural biodegradable, biocompatible, and antimicrobial layer of chitosan incorporating phenytoin-loaded pluronic nanomicelles for healing promotion and ciprofloxacin-alginate polyelectrolyte complex-based microparticles as antibacterial agent.

Growth performance, economic efficiency, meat quality, and gene expression in two broiler breeds fed different levels of tomato pomace.

Male broiler chicks (135 Indian River chicks (IR) and 135 Cobb chicks; n = 270) were weighed, wing banded, and distributed randomly into three iso-energetic and iso-nitrogenous diet groups for each breed (triplicate design, 45 bird/group, 15 bird/replicate). The chicks were fed the diets with levels of 0, 4, or 6% sun-dried tomato pomace (SDTP), respectively, for 42 consecutive days to determine the effect of consuming different levels of SDTP on growth performance, economic efficiency, meat quality, and gene expression in IR and Cobb broiler chickens. The inclusion of up to 6% SDTP in the diet of IR or Cobb chickens had no negative impact on growth performance parameters.

The impact of vitamin E and/or selenium dietary supplementation on growth parameters and expression levels of the growth-related genes in broilers.

Background: Broilers are continuously stressed because of the rapid growth rate and the environmental issues associated with industrialized poultry production systems, which lead to higher susceptibility for infection with pathogens. It is well known that vitamin E (Vit. E) and selenium (Se) supplementation have protective functions in such stressful conditions.
