A two-year-old female Dobermann dog was presented to the Veterinary Clinical Complex, Veterinary College and Research Institute, Orathanadu, Tamil Nadu Veterinary and Animal Sciences University, with a history of unilateral epistaxis, dullness, and inappetence. Clinical examination revealed the presence of ticks all over the body surface and they were morphologically identified as Rhipicephalus sanguineus. Blood samples were analyzed for haemato-biochemical parameters and blood parasites. Giemsa stained blood smear revealed the presence of morulae inclusion over monocytes. The dog was treated with a triple therapy protocol, and supportive care was provided. The dog exhibited signs of recovery from the third day of treatment. Follow-up examination on the seventh day revealedthe absence of morulae stage of Ehrlichia spp. and a gradual increase in blood cells. 

A nine year old non-descript male dog was presented to Madras Veterinary College Teaching Hospital with a history of anorexia, weakness, and clinical signs of respiratory distress and pyrexia. TFAST (thoracic-focused assessment with sonography for trauma) of the lung was performed to rule out pleural effusion. Upon confirmation of pleural effusion, thoracocentesis was performed and sample was collected to identify the cause. The pleural effusion was confirmed as haemothorax and cytology of the sample wasconfirmed as mesothelioma. 

With the aim to examine the effect of rearing systems on major meat quality traits in native ducks, appropriate experimental investigation was conducted. Research material included a total of 160 day-old native ducklings. The experiment was organized in two treatments with two replications each. Two different rearing systems were employed the intensive (cages) and extensive system (free-range). The native ducklings belonging to same hatch were procured from a local duck farmer and reared simultaneously for a period of ten weeks. Twelve ducks (six male and six female) from each treatment were chosen randomly and slaughtered at the end of rearing period to study meat quality traits in native ducks. Differences were significant (P<0.05) among sexes and rearing systems on pre slaughter live weight, eviscerated weight and various cut up parts, the corresponding values are higher for intensively reared ducks. Regarding sex, both male and female ducks exhibited differences considerably higher weight gain, carcass and cut up parts yield than that of female ducks.

Six dogs with unstable diaphyseal fracture of femur of different breeds of either sex and bodyweight ranging from 10 to 30 kg presented to the Small Animal Orthopedic Unit of the Madras Veterinary College Teaching Hospital, over a period of two years underwent fracture fixation with latest technique of linear locking compression plates. Different sizes and length of new generation locking plate system were used for different configuration of unstable fracture of femur. The post operative assessment of fracture healing was evaluated by radiographs at different intervals and estimation of bone specific serum alkaline phosphatase enzyme by fluorimetric methods. In the present study, the locking compression plating technique provided adequate apposition, stable fixation and promoted early weight bearing of traumatized limb. The locking plate system had a unique combi hole design in a single implant and enabled to select the function best suited for the fracture configuration to achieve the most stable fixation. The locking plate system acted as a single beam construct which increased the stiffness of the implant and was found appropriate in management of unstable or comminuted diaphyseal fracture of femur in dogs.

Restraining gadget for Indian poisonous snakes like Indian cobra and Russell’s Viper were designed, using available infrastructures. Tongs, collapsible tubes and bags were designed and applied in the poisonous snakes in order to have better restraining activities. These snakes reared at Guindy Snake Park Trust were successfully restrained, using the gadgets developed. However these gadgets were found not suitable for restraining procedure associated with Saw scaled viper and Common krait. The gadgets developed were useful for zoo veterinarians for control of these serpentines.

Gastrointestinal nematode parasitism is one of the major factors limiting sheep production worldwide because they cause heavy economic losses in meat and wool production. Gastrointestinal parasitism is the major cause for morbidity and mortality in ruminants. Severe anemia, reduction in functional gastric gland mass, severe damage to gastric mucosa and villous astropy caused by these worms are responsible for the death due to parasitic gastroenteritis. In India, the common nematode species encountered is Haemonchus contortus in small ruminants. This review throws light on the different mechanisms and contributory factors affecting the development of anthelmintic resistance, the diagnosis and means to prevent the resistance at field level. The emergence of multi-resistant nematode has shown that the previously used control strategies is no longer a chemically success method. The interpretation of fecal egg count reduction test has been modified and suggestions are made on its use with persistent anthelmintics. 

The main aim of this study was to investigate the effect of different concentrations of glutathione supplementation on liquid storage of Surti buffalo bull semen. This study was performed on adult Surti buffalo bull (n = 6), and seminal ejaculates (24) were collected and evaluated for various microscopic seminal quality parameters for further processing. After preliminary evaluation, ejaculates of each collection session were mixed and divided into four equal aliquots. All the aliquots were diluted (1:10) with Tris fructose egg yolk citrate extender contained glutathione served as control (T0), whereas the other three aliquots were supplemented with 0.5, 2.0 and 5.0 mM glutathione which were grouped as Treatment-1 (T1), Treatment-2 (T2) and Treatment-3 (T3), respectively. Thereafter, the samples were stored at 4 ºC for 4 h, and various seminal parameters (individual sperm progressive motility, viability, abnormalities, plasma membrane functionality) were evaluated at equilibration. The results indicated that the mean percent values for pre-freeze sperm progressive motility, live sperm percentage and HOS responsive spermatozoa were found to be significantly higher (P<0.05) (except individual progressive motility which was non-significantly higher in Treatment-3); whereas sperm abnormalities were significantly lower (P<0.05) in semen samples treated with glutathione (Treatment-1, Treatment-2 and Treatment-3) in comparison to control. The Treatment-2 (2.0 mM glutathione), had the highest pre-freeze sperm progressive motility percentage, live sperm percentage, HOS response sperm percentage and reduced sperm abnormalities percentage compared to other three groups.

The current study was designed to evaluate the carcass and meat quality characteristics of Siruvidai chicken of Tiruvannamalai, Dharmapuri, Ariyalur and Perambalur districts of Tamil Nadu.  The carcass characteristics namely New-York dressed weight, eviscerated carcass weight, ready-to-cook weight, giblets weight, abdominal fat weight and meat: bone ratio were recorded. No significant differences observed in carcass characteristics among the districts except for pre-slaughter weight and breast yield. A significantly (p ≤ 0.05) higher breast yield was recorded from Ariyalur and Perambalur districts. The pH, water holding capacity, shear force value, tyrosine value and thio-barbituric acid (TBA) number did not show significant differences among the districts. The Siruvidai chicken of Tamil Nadu is meant for egg production and mothering ability. From this study, it is concluded that Siruvidai chicken may be utilized economically for meat production and processing.

The study was conducted in Udaipur district of Rajasthan state selected purposely keeping in view of the fact that the district has highest population of  livestock in southern Rajasthan. A sample of 120 respondents was selected for the present study. The results indicated that a majority of farmers had medium level of Coordinating ability. Half (50%) of the small dairy farmers were found to have medium level of Planning ability while majority of medium category of dairy farmers had medium level of decision-making ability whereas in case of large farmer’s category, 58.82% of them exhibited high level of risk of dairy farming enterprise. The correlation analysis revealed the independent variables viz age, education, annual income, training, occupation, scientific orientation, extension and mass media were positively and significantly correlated with farmer’s Coordinating ability. However,  education, training, annual income, economic motivation, scientific orientation, market orientation, mass media were found to have positively and significant correlation with Planning ability of the respondents. The determinants, training, occupation, extension, annual income, mass media, economic motivation and scientific orientation were important variables which influenced Coordinating ability and Planning ability of dairy entrepreneurs.

An adult Nellore brown sheep was presented to Veterinary hospital with a history of swollen unilateral protrusion of left eyeball with congestion of conjunctival mucous membrane, exophthalmos condition since 5-6weeks. Clinical examination revealed blindness due to chronic keratitis and on palpation found a large fluid filled cyst in the left eye. With the surgical intervention the cyst was removed successfully along with its membrane from the retrobulbar region of the left eye and on parasitological examination it was diagnosed as Coenurus gaigeri cyst. Surgical intervention-involved treatment coupled with antibiotic therapy was proven to be an efficient way of managing retrobulbar coenurus cases.
