Sixteen gravid uteri of 1 st , 2 nd , 3 rd and 4 th month of pregnant Kundhi buffaloes were collected from Hyderabad slaughterhouse for this study. The ovaries were separated from gravid uteri of Kundhi buffaloes and ultrasonographic biometry was performed by ultrasound machine (HS-2000, Honda electronics Co. Ltd., Japan). The ovaries were examined for presence of follicles and/or corpus luteum. The length, width and height of ovaries and corpus luteum (CL) were recorded and measured. The average weight of ovaries with corpus luteum during 1 st , 2 nd , 3 rd and 4 th month's of pregnancy was 4.6 + 0.345, 5.90 + 1.134, 6.10 + 1.179, and 6.50 + 1.139 gms, respectively. The average weight of CL during 1 st , 2 nd , 3 rd and 4 th month of pregnancy was 2.0 +0.162, 2.4 + 0.35, 2.6 + 0.27, and 3.0 + 0.49 gm, respectively. The average weight of ovaries of non-gravid uterus of same buffaloes was 2.7 + 0.35, 3.6 + 1.10, 3.9 + 1.15, and 4.2 + 1.09 gm during 1 st , 2 nd , 3 rd and 4 th month of pregnancy respectively. The average size of the left and right ovary was 29.0 + 1.2 mm and 20.01 + 2.15 mm respectively and the average size of CL was 17.13 + 3.15 mm. There was significant increase in the weight, length, width and height of ovaries and corpus leutum as pregnancy advances than non-pregnant buffaloes. A greater number of ovarian structure (follicles) was found at the time of oestrus than anoestrus period.

Study was conducted to investigate the consequences of Theileriosis in naturally infected cattle and buffaloes of urban and peri urban areas of Hyderabad. Chemical analysis of milk of infected cows and buffaloes revealed that protein, ash and lactose were significantly declined (P<0.05) whereas, fat and total solids were significantly increased (P<0.05) in Theileria infected cows and buffaloes, but pH and acidity was unaffected. Financial losses occur in terms of reduced quality and severely decreased quantity of milk and meat. The total financial loss including the mortality and decreased quantity of milk and meat was recorded of Rs. 0.17 million / animal in the current study. Theileriosis is one of the main causes of financial losses for livestock holders.
