Effect of mint powder, Mentha longifolia, and vitamin D administration on growth indices of juvenile rainbow trout, Oncorhynchus mykiss

Numerous studies have shown that herbs can be used as growth stimulants in aquaculture. This study aimed to investigate the effect of combined consumption of mint powder and vitamin D on the growth and health of juvenile rainbow trout, Oncorhynchus mykiss. For this purpose, a total of 200 juvenile rainbow trout were divided into four groups and treated for 60 days as follows: The 1st group (control) used a standard diet; the 2nd group had 1.5% mint powder in their diet; The 3rd group having an additional amount of 120 mg/kg of vitamin D in their diet; The 4th group fed a diet having mint and vitamin D supplements as 2ed and 3rd groups. All groups' growth and health indices viz. condition factor, hepatic steatosis index, visceral sensitivity index, spleen somatic index, weight gain percentage, specific growth rate, feed conversion ratio, satiety index, food conversion efficiency, and protein efficiency ratio were measured and compared on days 20, 40, and 60. The results revealed that the use of mint powder in the juvenile rainbow trout diet not only had no remarkable effect on the growth and health of fish but also improved their growth. In addition, all the analyzed indications of the mint powder group outperformed than the vitamin D group

Effects of water shortage on food legume crops

The clamor for agricultural resources is being pushed up by global climatic change and population growth. Such consequences are huge challenges to food security, wreaking havoc on the agroecosystem and causing biotic and abiotic stresses in plants, which in turn cause metabolic and physiological problems. Food legume crops contribute to food security in underdeveloped countries by playing an essential role in conservation farming methods. Drought has, nevertheless, exhibited a negative impact on productivity in many parts of the world. While water shortage is a significant abiotic barrier to legume crop output, drought impacts differ depending on drought timing, agro-climatic area, soil texture, and legume species. To resolve these concerns, we gathered data from the recent publications that revealed drought-induced changes in the production of monoculture legumes in field circumstances and examined it using meta-analysis approaches. Research findings revealed that the water cut’s quantity was strongly associated with a decrease in yield. However, the magnitude of the effect differed depending on the phenological stage of the drought and legume species. The legumes such as groundnut and lentil exhibited the lowest yield reductions (31.2% and 19.6% for groundnut and lentil, accordingly), however, the biggest yield drop (39.8%) facing the maximum water reduction was for faba bean

Determination and Evaluation of Total Antioxidant Capacity of Oak (Quercus brantii), Thyme (Tymbra spicata), and Watermelon (Citrullus colocynthis) Native of Ilam

Background: Flock medicine has become a very important part of people's lives, however, it is not known by countries' rules in some cases. The usage of flock medicine has considerably increased in developed regions, as well, because of the effectiveness problems and the diverse side effects of artificial drugs. This research evaluated the antioxidant activities of Quercus brantii, Thymbra spicata, and Citrullus colocynthis native to Ilam province that nurtures within the west of Iran.Methods: The total antioxidant capacity of essential oils was measured via ELISA Reader at 570 nm.Results: The total antioxidant capacities of oak, thyme, and watermelon were 4.1, 2.35, and 0.46 (mmol Fe2+/L), respectively.Conclusion: The investigated traditional Iranian edible herbs are rich sources of natural antioxidant compounds.  As a result, T. spicata and Q. brantii could be used in pharmaceutical and food industries as natural antioxidants and food products
