Résumé
Introduction: Organic fertilizers are beneficial to maintain and improve structure of the soil nutrients; however, in case of presence of pathogenic microbial agents and pathogens inside them, it will result in health problems and disease transmission. Therefore, present study aimed to determine microbial quality of produced vermicomposts in Yazd city
Materials and Methods: This study was a descriptive-analytical work where 10 % of vermicomposts production centers which were using cow manure were randomly selected in Yazd city and sampling was conducted in spring. In doing so, the desired microbial indices were measured and ultimately compared to the standard A of Iranian compost. Three samples were prepared from each center and in each sampling; 50 g of sample was picked. Finally, total number of taken samples was 30. The tests included determination of the probable number of fecal coliform bacteria and parasite eggs
Results: According to the results of present study, the mean fecal coliform and parasite eggs for all centers were 1272 in confidence interval of 95 % [441-2102] and 0.73 in confidence interval of 95 % [0.32-1.13], respectively. Therefore, the mean fecal coliform and parasite eggs in derived vermicomposts were in class A standards range of Iranian compost
Conclusion: Production of vermicomposts by animal fertilizers in Yazd city not only decreases these wastes but also gives rise to manufacture a strategic and valuable product which is in range of determined standards and is suitable for soil improvement and fertility
Résumé
There are many advantages in breastfeeding of infants. The impact of fasting of breastfeeding mothers during Ramadan, on their exclusively breastfed infants' growth, is still unclear. The objective of this study is to determine the impact of maternal Ramadan fasting on growth parameters of exclusively breastfed infants. This cohort study was conducted on 55 healthy, exclusively breastfed infants, aged 1 to 6 months, during Ramadan and three months after it. 20 infants, whose mothers fasted throughout Ramadan [case group] and 35 infants, whose mothers did not fast [control group], were enrolled in the study. All infants underwent periodic physical examinations, twice in Ramadan and 3 times in the first, second and the third months after Ramadan. The data analyses were done using a repeated measure analysis of variance. Statistical significance was defined as P<0.05. Analyses were performed using SPSS statistical package and repeated measures ANOVA. The average age was 3.43 +/- 1.38 months in the case group and 2.31 +/- 1.45 months in the control group that presence no significant difference between. From the total number of infants, 23 cases [41.8%] were males and the rest were females. All growth parameters increased during the study period [P<0.05], with the same rate of increase for both groups [P=0.125]. Ramadan fasting by breastfeeding mothers did not adversely affect the growth parameters of exclusively breastfed infants in short-term
