Due to their distinctive properties, several eco-friendly metal oxide nanoparticles were assessed for their possible cardioprotective properties. Acrylamide (ACD), a pervasive chemical in food and the environment, has been linked to cardiac toxicity. Therefore, this study examined the probable protective effect of green synthesized zinc oxide nanoparticles (GS-ZNPs) against ACD-oral exposure-induced cardiac damage in rats.

The terrible reality is that acrylamide (AA) is a common food contaminant found in a wide variety of commonly consumed foods. This research involves the advancement of a more dependable technique for the bio-fabrication of zinc oxide nanoparticles (ZNPs) through the green method using Moringa Oleifera extract (MO-ZNPs) as an efficient chelating agent for acrylamide (AA). The effects of AA on glutathione redox dynamics, liver function, lipid profile, and zinc residues in Sprague Dawley rats are investigated.

Article Synopsis
  • Bee bread extract (BBE) was studied for its potential to enhance the quality of cryopreserved ram semen when added to egg yolk extender (EYE) or soybean lecithin extender (SBLE).
  • The study found that SBLE outperformed EYE in preserving semen quality, with significant improvements in sperm motility, viability, and membrane integrity when supplemented with BBE.
  • BBE not only enhanced sperm characteristics but also boosted antioxidant activity and reduced sperm apoptosis, indicating its beneficial role in semen cryopreservation.

Chronic respiratory disease (CRD) caused by Mycoplasma gallisepticum (MG) leads to impaired broiler growth performance and significant economic losses worldwide. The utilization of essential oils (EOs) as natural alternatives to antibiotics to control CRD outbreaks is not completely clarified yet. Thus, we investigated the effect of a commercial EOs mixture (toldin CRD), in comparison to tilmicosin antibiotic, on the clinical observations, growth performance, immunity, digestive enzymes, gut barrier functions, and bacterial loads in broilers experimentally infected with MG.

The aim was to evaluate the performance, blood lipid profile, and the relative expression of growth-related genes in purebred white and brown quail lines and their crossbred lines. A total of 240 one-day-old Japanese quail chicks of white and brown line, their crossbred line (WBQ: male white × female brown), and reciprocal crossbred line (BWQ: male brown × female white) were divided into four equal groups (60 birds each). The white quail line showed significantly higher final body weight, daily gain, and feed intake compared with the other quail lines (p < 0.
