Evaluating the effectiveness and safety of a novel phage cocktail as a biocontrol of in biofilm, food products, and broiler chicken.

is a foodborne pathogen of animal and public health significance. Considering the disadvantages of antibiotics or chemical preservatives traditionally used to eliminate this pathogen, attention has shifted, in recent years, toward biocontrol agents such as bacteriophages, used either separately or in combination to prevent food contamination. However, extensive use of phage-based biocontrol agents in the food industry requires further studies to ensure their safety and efficacy.

Relative bioavailability of L-methionine and DL-methionine in growing broilers.

Two separate studies were conducted in growing broiler chickens to examine the relative bioavailability (RBA) of L-smethionine (L-Met) vs. DL-methionine (DL-Met) in the starter (0-10 d, Experiment 1) and grower (11-24 d, Experiment 2) periods. In each experiment, 540 male Arian broilers were weighed and randomly allocated to nine dietary treatments in a completely randomized design with 6 replicates: basal diet (BD) with no methionine (Met) supplementation and eight diets supplemented with incremental levels (0.

Investigating the relationship between aging perception and self-efficacy in the older adults: a cross-sectional study in Eastern Iran.

Background: With the global increase in the older adults population, understanding factors that impact their quality of life is crucial. The perception of aging and self-efficacy are significant factors affecting older adults health outcomes. This descriptive cross-sectional study investigates the relationship between Aging Perception and self-efficacyamong older adults individuals in Birjand city, a demographic that is rapidly increasing but under-research.

Effects of hydroxytyrosol on post-thaw quality of rooster sperm.

Semen cryopreservation is one of the most important reproduction techniques in the livestock and poultry industry. Cryopreservation induces cold stress, generating reactive oxygen species (ROS) and oxidative stress causing structural and biochemical damages in sperm. In this study, we evaluated the effects of the hydroxytyrosol (HT), as an antioxidant, at the concentrations of 0, 25, 50, and 100 μg/mL on post-thaw semen quality metrics in rooster.

Effects of the algae derivatives on performance, intestinal histomorphology, ileal microflora, and egg yolk biochemistry of laying Japanese quail.

We examined the effect of the Persian Gulf algae derivates, phycocyanin (PC) and fucoidan (FUC), on production performance, egg quality, intestinal histomorphology, ileal microflora, and egg yolk biochemistry of laying Japanese quail. A total of 250 six-wk-old Japanese quails with an average body weight of 215 ± 10 g were allocated to 5 treatments, 5 replicates and 10 birds in each replicate in a completely randomized design. The treatment groups received PC (from Spirulina platensis) and FUC (from brown seaweed) in their drinking water while control groups did not.
