Identification of risk factors is important for the design of control programmes for mastitis in cows. Information about farms and management was collected at a farm visit. California Mastitis Test (CMT) was performed to assess sub-clinical mastitis, and cows, udder and milk were examined for clinical mastitis. A total of 347 lactating cows from 83 farms in the dry season (November - February) and 388 lactating cows from 89 farms in the wet season (June - October) were studied. The overall prevalence of mastitis was 19.9% and 44.8% in dry and wet seasons, respectively. The prevalence of mild mastitis was 17.3% and 40.7%, whereas that of moderate mastitis was 2.6% and 4.1% in dry and wet seasons, respectively. The prevalence of mastitis was higher (P

A field experiment was conducted to find out the effect to different levels of nitrogen and phosphorus on yield, oil contents and quality and nutrient uptake of soybean. The maximum plant height and number of pod per plant were recorded by the application of 40kg N / ha. Single application of phosphorus also bring significant increased in oil content of soybean. Nitrogen, phosphorus, potash content of soybean seed and straw varied with different treatment of NP. Interaction showed oil content of soybean was influenced with increasing level of nitrogen and phosphorus. The percent of oil and yield of soybean were found maximized by the application of 40kg N / ha + 30kg P 2 O 5 / ha. However, moisture, density, refractive index and peroxide value of soybean oil remain more or less same throughout the experiment.

Primary hypothyroidism is a common clinical condition. Ascites caused by hypothyroidism is rare. So its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a male person of 58 years with hypothyroidism with ascites who responded well with thyroid hormone replacement therapy with complete resolution of ascites. Analyses of ascites from patients in this condition usually shows exudative ascites with high protein (>2.5 g/dL) and SAAG < 1.1 gm/dl. High index of suspicion is required to reach at such diagnosis. Though it is a rare but prognosis is excellent with replacement therapy. Key words: Ascites, Hypothyroidism. doi: 10.3329/jom.v10i2.2828 J MEDICINE 2009; 10 : 121-123
