  The aim of this study was to assess the relationship between milk urea nitrogen (MUN) level and reproductive performance in high yielding dairy cattle houses in Tabriz, Iran. Among 213 selected dairy cattle, 76 heads (35.7%) have MUN < 16.00mg/dl (mean = 15.38 mg/dl) More

  The aim of this study was to assess the relationship between milk urea nitrogen (MUN) level and reproductive performance in high yielding dairy cattle houses in Tabriz, Iran. Among 213 selected dairy cattle, 76 heads (35.7%) have MUN < 16.00mg/dl (mean = 15.38 mg/dl) and 137 heads (64.3%) have MUN > 16 mg/dl (mean = 17.46 mg/dl). Our results indicated that MUN level in 81 heads of dairy cattle (total 124 heads) with mastitis, dystocia, laminitis, uterine infections or placenta replacement was higher than 16 mg/dl. We only observed a significantly positive association between MUN levels and dystocia (p= 0.032), while the association between MUN levels and incidence of other diseases was not statistically significant. The results of this study indicated that MUN level significantly influences the reproductive parameters including days open, calving to first service, first service conception risk, and number of services per conception (p<0.001). We concluded that measurement of MUN level in dairy cattle may be an effective approach to assess the outcome of the nitrogenous ingredients of ratios and prediction of reproductive status in post parturition stage.  Manuscript profile

  Background and Objective: Diabet mellitus is a chronic disease. In this disorder, due to abnormal glucose metabolism, direct and indirect complications in many organ systems, including ocular, cardio-vascular, vernal, and cerebral and suppression of immune system have been occurred. Decreasing of both cellular and humoral immune system is a important factor for opportunistic infections. Prevention and control of these infections and recognize of their frequency and risk factor is very important. Material and Methods: In this study, 118 diabetic patients that admitted in Islamic Azad University hospitals were included. Chief complaint of every patient, important finding in clinical examinations and results of microbial culturing from opportunistic infections had been analyzed. Result: From 118 patients, 65 cases (55%) were female and 53 cases (45%) were male. Mean age of patients was 59.6 ± 11.7 years old and mean duration time of disease was 13.6 ± 7.8 years. Thirty one cases (26.1%) infected by opportunistic bacterial. From patient's samples (in microbial culturing), 12 cases (38.5%0 Escherichia coli, 9 cases (29%) fungal pathogens, 5 cases (16.3%0 staphylococcus aurous and 5 cases (16.3%0 Pseudomonas aeruginosa were isolated. Conclusion: Because of high frequency of infections in diabetic patients, using of preventing methods is important. On the other hand, diagnostic and treatment of these infections prevent from their complications. Manuscript profile

  In this study, the effect of adding prebiotic, synbiotic and phytobiotic supplements in the diet on growth performance, carcass traits, apparent digestibility of nutrients and some blood parameters of fattening Zell lambs was investigated. For this purpose, 24 Zell male lambs with an avrage age of about 5 months and an avrage weight of 25.4±0.50 were used for 90 days. The experimental treatments included 1- control group (no supplement), 2- treatment containing 2 g of A-Max prebiotic supplement, 3- treatment containing 4 g of Biomin IMBO synbiotic supplement, and 4- treatment containing 6 g of Bioherbal phytobiotic supplement per head of lamb per day. The growth performance results showed that there was a significant difference between the experimental treatments in the fattening weight, dry matter intake, daily weight gain and feed conversion ratio (p < 0.05). The highest weight at the end of the fattening period, dry matter intake and daily weight gain were observed in the treatment of 4 g of synbiotic supplement. The treatment with 6 g of phytobiotic supplement had the lowest feed conversion ratio. The highest apparent digestibility of dry matter, NDF and ADF was observed in the treatment of 4 g of synbiotic supplement (p < 0.05). The results of some blood serum parameters showed that there was a significant difference in the concentration of glucose, cholesterol, triglyceride and blood urea nitrogen between the experimental treatments (p < 0.05). The highest concentration of glucose was in the treatment of 4 g of synbiotic supplement, the lowest concentration of cholesterol was in the treatment of 6 g of phytobiotic supplement. Blood urea nitrogen had the lowest concentration in the treatment of 4 g of synbiotic supplement. The treatment with 4 g of synbiotic supplement had the highest hot carcass weight, hot carcass percentage, cold carcass weight, cold carcass percentage, thigh percentage and shoulder percentage (p < 0.05). The present research showed that the addition of 4 g of synbiotic supplement in the diet improved the growth performance, valuable parts of the carcass and the apparent digestibility of nutrients in fattening lambs.
