Background and aim: The aim of this research was to investigate the effect of vitamin E and selenium on mastitis treatment outcome and Malondialdehyde (MDA) and vitamin D level in serum.
Materials and methods: In this study 3 groups of cows were evaluated, which are as follows: 1.The control group that did not have clinical mastitis and other inflammatory diseases. 2. Experimental group (1) that had clinical mastitis underwent routine field treatment. 3. Experimental group (2) that had clinical mastitis underwent routine field treatment along with vitamin E and selenium. After disinfecting, blood samples were obtained from jugular vein by clot tube and venoject at the both time of diagnosis and recovery. The level of vitamin D was assayed by chromatography and MDA was measured by ELISA method.
Results: The results showed that the average levels of vitamin D in serum of mastitic cows were lower and MDA was upper than healthy cows as there was a significant difference between sick groups (mastitic cows) and healthy cows in those parameters. It was also determined that vitamin D level had increased and MDA decreased in the treated cows in the recovery period. According to the findings of this research it is obvious that in experimental group (2) vitamin E and selenium consumption had led to a significant decrease in MDA and increased vitamin D level in serum as there was a significant difference between the time of diagnosis and recovery in experimental group (2).
Conclusion: Therefore, it can be said that although the vitamin E and selenium consumption is seemingly increased body resistance and the level of vitamin D and decreased in MDA levels in the recovery period and prevented the disease from becoming chronic, there was no clinically improvement in the recovery process.

Controlling diabetes as a widespread metabolic disease and the cause of death of millions of people around the world, with effective alternative therapies, is now a topic of concern. In recent years, strong evidence based on the beneficial effects of camel milk on the control and treatment of type 1 and type 2 diabetes has been found in both human and animal models. In this article, we reviewed studies that have evaluated the effects of camel milk on glucose, plasma insulin, and lipid profiles (total cholesterol and triglycerides) in animals with type 2 induced diabetes. The present article includes 8 studies in animal phase, two of which were performed on alloxan-induced type 2 diabetic dogs and one on alloxan-induced type 2 diabetic rabbits, and the rest were on Streptozotocin-induced (STZ) type 2 diabetic rats. Except one study, all studies showed that camel milk was about 40 to 50 percent effective in controlling blood sugar and insulin sensitivity, as well as a 20 to 35 percent improvement in lipid profile in diabetic animals treated with camel milk compared with controls or feeding groups with cow milk or untreated diabetic groups. In addition, the use of drugs such as Rosiglitazone Maleate and Glibenclamide along with camel milk play a significant role in the improvement and better management of type 2 diabetes. The studies have also shown that consuming cow's milk in animals with type 2 diabetes not only does not improve glucose levels and lipid profiles, but also increases blood glucose levels by about 20 to 30 percent.

Background and purpose: Today, cow's milk is one of the most important and widely used animal milks fed by humans and a unique source of food for all ages. Contamination of milk with heavy metals such as lead, mercury and cadmium is regarded a risk to human health. Poisoning with lead, mercury and cadmium has adverse effects on human health, which is much more common during childhood. Therefore, this study was conducted with the purpose of investigating lead, mercury and cadmium concentrations in raw milk of cattle ranchings located around Jiroft city in 2021.
Materials and methods: After selecting 10 cattle ranching randomly around Jiroft city and preparing 10 samples in the laboratory, the acidic digestion of the samples was performed according to AOAC method. Then, the elements concentrations were measured based on Graphite Furnace Atomic Absorption Spectrometry. SPSS software was used for statistical processing of the results.
Results: The results showed that the mean concentrations of elements for lead, cadmium and mercury were 0.013647, 0.0012520 and 0.002 mg/l, respectively. According to international standards (Codex) and the national standard of Iran, the accumulated mean concentration of lead (ppm 1), cadmium (ppm 0.01) and mercury in the samples was within the permissible range and samples measurement showed that the amount of lead, cadmium and mercury was less than standard and in only one sample, the amount of lead exceeded the standard.
Conclusion: The result of this study showed that the levels of lead, cadmium and mercury in Jiroft are standard and permissible. However, in order to increase the safety and health of the consumers, it is suggested that more monitoring be done on livestock farms and industrial centers adjacent to livestock farms.
