The impact of dietary probiotic supplementation on welfare and growth performance of Nile tilapia ().

Background: The usage of commercial probiotic products as alternatives to traditional antibiotics in fish culture is initiated to be a potential factor for Nile tilapia fish's welfare and growth.

Aim: The purpose of the current study is to show the influence of commercial probiotics () dietary supplementation at different levels on Nile tilapia welfare and growth.

Methods: Apparently healthy fingerlings of Nile Tilapia with a total number of 120 with an average initial weight (26.

Apitoxin alleviates methyl mercury-induced peripheral neurotoxicity in male rats by regulating dorsal root ganglia neuronal degeneration and oxidative stress.

Methylmercury (MeHg) toxicity is associated with extensive neuronal degeneration of dorsal root ganglia (DRG). This study aimed to assess the ameliorative effect of bee venom (BV) on methyl mercury chloride (MeHgCl)-induced peripheral neurotoxicity using DRGs in rats. Forty-eight adult male Sprague Dawley rats were allocated into four equal groups: G I: control (gavaged MilliQ water 1 ml/rat), G II: subcutaneously injected with BV (0.

Impact of Dietary Egg Yolk IgY Powder on Behavior, Meat Quality, Physiology, and Intestinal Colonization of Broiler Chicks.

The current study investigated the impact of different concentrations of purified egg yolk immunoglobulin Y (IgY) supplemental food on the growth performance, behaviors, cecal contents of , and the meat quality of broiler chicks. Four dietary groups were given to 180 female Ross broiler chicks at random ( = 45 for each). The control group was fed a standard diet only, whereas the other three experimental groups were fed the same basic diet supplemented with 1,500, 3,000, and 4,000 μg/ml IgY for a duration of 42 days.

Impact of mycogenic zinc nanoparticles on performance, behavior, immune response, and microbial load in .

This work aims to evaluate the antibacterial activity of biological zinc nanoparticles (BIO-ZnONPs) against pathogenic fish bacteria and assess the effect of BIO-ZnONPs on the performance, behavior, and immune response in Nile tilapia () as compared to chemical zinc nanoparticles (CH- ZnONPs). Aspergillus niger TS16 fabricated the BIO-ZnONPs were spherical shape with the average size of 45 nm and net charge of -27.23 mV.

Bee venom Apis mellifera lamarckii rescues blood brain barrier damage and neurobehavioral changes induced by methyl mercury via regulating tight junction proteins expression in rat cerebellum.

The objective of the current study is to investigate the protective effect of Egyptian bee venom (BV) against methyl mercury chloride (MMC) induced blood-brain barrier (BBB) damage and neurobehavioral changes. Eighty male Sprague-Dawley rats were randomly grouped into 1 control (C), 2 BV (0.5 mg/kg S/C for14 days), 3 MMC (6.

Influence of gender, neuter status, and training method on police dog narcotics olfaction performance, behavior and welfare.

Objective: This study was carried out to study the influence of gender, neuter status, and training method on police dog narcotics olfaction performance, behavior, and welfare.

Materials And Methods: A total of 120 German Shepherds aged 1-3 years were used for this study. The dogs were separated into two experiments.

Influence of housing systems on duck behavior and welfare.

Objective: This experiment was conducted to assess the effects of the housing system on the welfare and growth performance of the Muscovy duck.

Materials And Methods: A total number of 48 Muscovy duck aged 3-week old were divided randomly into two groups (24 duck on each): deep litter system and cage system. Each group was subdivided into three replicates (8 birds on each) were identified with wing rings.
