The present study was undertaken with six numbers of German Shepherd dogs from different locations of Belgachia, Kolkata, West Bengal. Semen samples were collected biweekly in the morning (8:00 hr) by massage method aseptically from each dog for six occasions. A total of 36 ejaculates were collected. After collection, all semen samples were pooled, and all the macroscopic characters and physicomorphological seminal characteristics were evaluated. The volume of semen, pH, sperm concentration, individual motility, live percentage of spermatozoa, positive for hypo-osmotic swelling test( HOST) and total sperm abnormality percentage were 5.516 ± 0166 cu mm., 6.383 ± 0.031, 274.333 ± 2.667 x10 6 /mL, 76.333 ± 2.728%, 84.166 ± 1.990, 80.166 ± 2.522 and 14.83 ± 2.386, respectively. In the study all the dogs were found fertile.

Background: Canine Transmissible Venereal Tumor (TVT) is a commonly occurring contagious reproductive tumor of dogs affecting both sexes. Methods: Six female mongrel dogs were brought to Veterinary clinical complex, WBUAFS, Belgachia, Kolkata with the history of inappetence, mass swelling on genitalia and blood tinged urine with dysuria for the past two weeks. Following Physical examination, protruded mass was noticed on external genital region. Impression smear was collected from protruded mass for confirmation of vacuole cell. Chemotherapy was applied with Vincristine @ 0.025 mg/kg b.wt; slow IV once a week for 4 weeks along with supportive treatment. Result: After the end of the 4th week of Chemotherapy animals were showed uneventful recovery.

In the present study, blood samples of 79 cows with different uterine infections (pyometra, endometritis, cervicitis and abortion) and 41 normal cows of non-descripts and crossbreds were collected to study the prevalence of uterine infection in relation to haematological as well as biochemical changes in blood serum. In uterine infections, major infection remained endometritis which was recorded as highest (34.16%) followed by pyometra (18.33%), cervicitis (10.00%) and abortion (3.33%). Haematological study revealed a significant decrease in haemoglobin and total erythrocyte count while a significant increase in total leukocyte count in animals with uterine infection as compared to the control group. Biochemical study revealed that there was a severe decrease in serum glucose and serum cholesterol level in uterine infected cows in comparison to healthy cows. It was concluded that infection in the body, nature of the causative agents, and resistance of animal and localization of inflammatory response might be possible causes of lower biochemical parameters and haematological parameters except total leukocyte count in uterine infected cows.
