Article Synopsis
  • The study aimed to improve the quality of death notification forms (DNFs) at Assiut University Children Hospital (AUCH) to enhance mortality statistics and public health efforts, particularly since Egypt has low-quality death registration data according to WHO.
  • A quasi-experimental design provided training on the accurate reporting of causes of death for 100 residents, alongside a six-month audit of DNFs to improve knowledge and reporting accuracy.
  • Results showed a significant increase in knowledge among physicians and reduced errors in DNFs, notably a decrease in incorrect reporting of death mechanisms from 90% to 18%, demonstrating the effectiveness of the training and auditing intervention.

This study examined the impacts of dietary spirulina (SP) and canthaxanthin (CX) supplementation to laying hens on reproductive performance and cock's semen quality evaluation. Three hundred and sixty of indigenous Sinai chickens (300 hens + 60 cocks), 48-weeks-old, were randomly divided into five treatments; a control and four supplemented (0.6 g SP mg/kg, 0.

A total number of 300 (225 ducks and 75 drakes) Sudani ducks, 28-wk-old were divided into five groups to investigate the effects of dietary L-carnitine (LC) supplementation on productive, hatching and physiological performance as well as nutrients digestibility coefficients. The results indicated that the productive performance and Semen quality parameters (ejaculate volume, sperms concentration and advanced motility) were significantly improved by LC supplementation (150-450 mg /kg diet) as compared to the control. Hatchability of fertile eggs (%) was significantly improved, while total embryonic mortality was significantly decreased by supplementing 300 and 450 mg LC/kg diet.
