Products made from chicken meat have gained popularity in recent years in both developed and developing countries, and they can help with the scarcity of the red meat. They provide abundant, easily digestible protein and offer essential vitamins and minerals like niacin, thiamine, and riboflavin, crucial for maintaining life, promoting development, and providing various health benefits. Despite having a high biological value, chicken meat products can nevertheless contain various food spoilage and poisoning organisms such as E. coli. This study was undertaken to investigate the prevalence of E. coli in the retailed chicken meat products in Egypt including chicken luncheon, nuggets, and pane. Besides, the anti-E. coli activities of natural products including papaya and moringa extracts were examined. The obtained results revealed coliform contamination of the examined chicken meat products. In addition, E. coli was isolated from the examined chicken luncheon, nuggets and pane at 35%, 65%, and 50%. E. coli O2:H6, O26:H11, O78, O91:H21, O121:H7, O128:H2, and O146:H21 were the recovered serotypes with E. coli O128:H2 the most predominant serotype. The recovered serotypes harbored Shiga toxin coding genes. Both papaya and moringa extracts could significantly reduce E. coli load in an experimental trial.

Ill-thrift or poor growth in small ruminants is a global concern for both veterinarians and small ruminants' producers. The aim of this study was to assess the risk factors of ill-thrift and the associated clinicopathological changes. Smallholder farms were the source of 150 goats used in the study. Based on clinical findings and body condition score (BCS), the goats were classified into 3 groups: emaciated (BCS 1, n = 46), thin (BCS 1.5-2, n = 52), and control (BCS≥2.5, n = 52), respectively . Blood samples were used for clinicopathological investigations, and risk factors were tested. Goats suffering from emaciation had a significant decrease in haemoglobin (HGB) (P= 0.012), mean corpuscular haemoglobin (MCH) (P= 0.029), mean corpuscular haemoglobin concentration (MCHC) (P=0.03), albumin (P=0.009), sodium (Na) (P=0.039), iron (Fe) (P=0.004), copper (Cu) (P=0.022), and selenium (Se) (P= 0.027) compared to the control group. White blood cell count and globulin levels, on the other hand, were significantly elevated in the emaciated group (P= 0.0001, and P= 0.039, respectively). Goats aged ≤ 2 years (odds ratio (OR): 6.5, P = 0.0001), female goats (OR: 10.1, P = 0.0001), and those fed on unbalanced rations (OR: 13.3, P = 0.032) were at higher risk of ill-thrift. In conclusion, this study evidenced that ill-thrift is associated with significant alterations in the haematological and biochemical profiles. Young age, gender, and unbalanced rations are the potential risk factors for ill-thrift in goats. Recognition of risk factors associated with ill-thrift provides valuable insights for prevention and management programs.

Leveraging solar energy through hybrid solar-driven interfacial evaporation is a hopeful way to couple clean water production and electricity generation simultaneously. In this context, a yolk-shell structure made of paraffin wax combined with expanded graphite (PW@EG) was used as a cost-effective and efficient evaporator. A yolk-shell structure was fabricated by encapsulating PW within a SiO₂ shell. Subsequently, the EG outer shell was coated onto the PW/SiO₂ microcapsules. The silica shell segregating the external EG shell from the PW core was eliminated utilizing HCl, forming a yolk-shell structure (PW@EG). The core@void@shell enables multiple reflections of solar light through the interior voids, enhancing light utilization efficiency. As a result, the prepared structure demonstrates exceptional capability for wide-spectrum solar absorption and photothermal transformation, fast water movement, and good thermal management. Exploiting these attributes, the bi-layer solar evaporator depicted a high evaporation rate of 1.314 kg m^-2h⁻¹ and an evaporation capability of 91.0 % under one sun’s illumination. Moreover, incorporating the bilayer evaporator with a thermoelectric module facilitates the transformation of waste heat into electricity. This hybrid device depicts output power density up to 150.2 mWm⁻².
