Article Synopsis
- The study examined the effects of dietary saffron petal extract on laying hens over 12 weeks, focusing on egg quality, blood metabolites, and odor emissions from waste.
- Results revealed that while egg protein, fat, and ash content remained mostly unchanged, a significant reduction in yolk cholesterol was observed, along with improved egg production in hens fed the 80 ppm saffron diet.
- Supplementation with saffron petal extract also lowered serum cholesterol and blood glucose levels, but did not significantly affect feed intake or mineral excretion.
Article Synopsis
- The study investigates the impact of adding hydroalcoholic extracts of saffron petals, yeast cell walls, and bentonite to the diets of broiler chickens contaminated with aflatoxin B and ochratoxin A.
- Results show that incorporating these additives improves the growth and health of the chickens by enhancing carcass weight, lowering harmful enzyme levels, and improving small intestine morphology compared to those on a positive control diet.
- The findings suggest that saffron petal extract, especially at 750 mg/kg, is effective in mitigating the negative effects of these toxins in broiler diets.
Metal nanoparticles, often supported on metal oxide promoters, are a cornerstone of heterogeneous catalysis. Experimentally, size effects are well-established and are manifested through changes to catalyst selectivity, activity and durability. Density Functional Theory (DFT) calculations have provided an attractive way to study these effects and rationalise the change in nanoparticle properties.

Herbal essential oils (EOs) have been proposed as a suitable alternative to chemical drugs in intensive production management systems for better performance of broilers with slight side effects and admirable therapeutic properties.
Objectives: This experiment was conducted to investigate the effects of feeding cholecalciferol (VD) in combination of Satureja rechingeri EO (SREO) on growth performance, haematological indicators and immunological response of broilers.
Article Synopsis
- - Neonatal diabetes mellitus (NDM) is a rare genetic disorder affecting infants, mainly identified in the first 6 months of life, with most cases linked to gene mutations that impact insulin production and beta-cell health.
- - A study in Iran involving 135 patients diagnosed with diabetes before age 12 months revealed genetic abnormalities in 93 individuals, with a notable prevalence of consanguineous marriages and a significant familial history of diabetes.
- - Researchers discovered 58 unique genetic variants in 14 genes related to NDM, with the highest occurrences in EIF2AK3, KCNJ11, and ABCC8, including 20 variants identified for the first time, enhancing understanding of NDM genetics in this population.
