A study was conducted to analyse the migratory sheep production system in southern agro-climatic zone of Tamil Nadu. A total of 100 migratory sheep farmers were randomly selected for the study and divided as small (< 175), medium (175- 350) and large (> 350) flocks based on the average flock size for comparison. The migratory tracts were identified based on the results of the enquiry from the sheep farmers, animal husbandry department personnel and by direct identification. A total number of 78 migratory tracts comprising 28 major and 50 minor tracts were identified in the study area. The mean radial distance (km) of migration in major tracts was 317.00±6.21 and minor tract was 148.40±6.21. 

An experiment was conducted to study the influence of sprouted green gram, selenium and vitamin E and their combinations on reproductive performance like semen quality and fertility for a period of five weeks with forty two adult White Leghorn cocks and seventy White Leghorn hens which were divided into seven treatment groups containing six cocks and ten hens for each treatment. The treatment groups consisted of control (T1), sprouted grains 50g/kg (T2), selenium 0.5mg/kg (T3), vitamin E 500mg/kg (T4), sprouted grains 50g/kg + selenium 0.5mg/kg (T5), sprouted grains 50g/kg + vitamin E 500mg/kg (T6) and sprouted grains 50g/kg + selenium 0.5mg/kg + vitamin E 500mg/kg (T7). Significant (P<0.05) difference was observed between treatment groups. The overall sperm motility of treatment and control groups did not differ significantly. The sperm concentration was significantly (P<0.05) higher in all treatment groups compared to control.  Inclusion of sprouted green gram, selenium and vitamin E had significantly reduced the overall dead (P<0.01) and abnormal (P<0.05) sperms when compared to the control group. 

Investigation was carried out in response to a report of mortality among Jersey crossbred dairy cattle at Therkumedu village, Tirunelveli district which were purchased from Chittoor district, Andhra Pradesh. Clinical examination was carried out in 38 animals. Most of the animals showed signs of general weakness, dullness, anaemia, icteric mucus membrane, lymphadenopathy, acariasis, bruxism, debility and passing semisolid faeces  coated with mucus. Blood smear examination revealed the presence of T. annulata piroplasm and A. marginale inclusions. All the affected animals were treated with Buparvaquone @ 2.5 mg/kg and Oxytetracycline @ 20 mg/kg for 7 days supported with parenteral haematinics (Tribivet) and liver extract. Control of ectoparasites was effected with cypermethrin @ 0.2 per cent as external application and 0.4 per cent spray in animal sheds. All the treated  animals recovered slowly and became normal.

A study was undertaken to assess the effect of betel leaves (Piper betel Linn) extract on the physico-chemical, sensory and antioxidant properties of khoa made from cow’s milk and stored under room temperature. The physico-chemical parameters viz., pH, titratable acidity, fat, free fatty acids, sensory and antioxidant properties were evaluated periodically at an interval of 3 days upto 9 days. The  result revealed that sensory evaluation of khoa was not influenced by the presence of 0.5 per cent aqueous extract of betel leaves up to 9 days of storage period with an overall acceptability score of 6.83. The physico- chemical properties of khoa showed an increasing trend in acidity and decrease of pH as the storage period progresses. The free fatty acids levels were well within the prescribed limit because of antioxidant properties exhibited by the aqueous extract of betel leaves. From the study, it was concluded that khoa with 0.5 aqueous extract of betel leaves restricted the production of free fatty acid compared to control due to antioxidant property of betel leaves.

Animals of all ages are susceptible for chocolate toxicity affecting many organ systems. The case presented here is of male German shepherd aged 4 years was accidentally encountered with chocolate toxicity with excessive salivation, vomition, diarrhoea, restlessness and incoordination like systems. The dog was treated symptomatically using rehydrated fluids, atropine sulphate and dexamethasone along with other supportive medication immediately. The dog was recovered completely within week of post treatment. 

The data on 1721 calves from Sahiwal and Jersey-Sahiwal crossbred cattle were utilized for studying the age specific mortality and culling rate. The overall mortality and culling rate were found to be 15.92 and 19.52 per cent in Sahiwal and Jersey crossbreds respectively. The average female calf mortality from 0-1, 1-3, 3-6, 6-12 and 12 month to age at first calving was observed as 5.81, 2.92, 2.06, 1.75 and 5.01 per cent, respectively. The genetic group had no significant effect on female calves mortality. The maximum culling rate was observed from 12 month to AFC.

The equine species, which includes donkeys, mules, horses, and ponies, have made major contributions to human civilizations all throughout the world. The Indian livestock sector, after an initial decline in period from 2007 - 2012, staged a remarkable comeback during the period from 2012-2019 with an impressive overall growth rate of 4.8%. However, the total population of horses, ponies, mules and donkeys in India is 0.55 million as per the latest livestock census, a decrease by 51.9% over the previous livestock census (2012). The ‘decreasing utility’ due to increasing vehicles and urbanization has been considered as factors for the drastic dip in population. This paper, based on secondary data, aims to provide a concise summary of the current status, growth rate, distribution patterns, and factors leading to the decline in the population of working equines in India. Tabular presentations and graphical representations have been utilized for easy analysis and comparison of population trends across different years.

Avian species reproduce sexually by the fusion of male and female gamete spermatogonia and oogonia-produced by differentiated testes and ovaries. Fertilization is internal and all birds are oviparous. Reproduction in birds entirely varies from other animals. The two essential reproductive organs ere the ovary and oviduct which were involved in the synthesis of egg in adult laying hen. Gross and morphometrical studies were carried out on the female reproductive tract in twelve Siruvidai chicken of which six at laying phase and six at broodiness phase. The birds were reared in Poultry Research Station, Madhavaram, Chennai-51. In laying phase, the left ovary showed mature ovarian follicles whereas the ovary during broodiness phase was in the form of a bunch of grapes with no hierarchical follicles. There was no significant difference in the body weight of the bird during laying and broodiness. The mean length, weight and width of ovary and oviduct had a highly significant difference during laying and broodiness phase. Gross morphology revealed that only the left female reproductive tract was well-developed both during laying and broodiness phase and the morphometric data analyzed will provide a baseline for subsequent studies and also for comparison with other avian species.

The study was carried out to evaluate the feasibility and efficacy of digital planimetry apps for wound measurement in dogs. Twenty four clinical cases of dogs with the history of wound presented for wound management were randomly divided into four groups consisting of six animals each and wound measurements were taken on 0, 2, 4 and 7th day. The wound was measured with length, breadth, area and circumference using Imito Measure mobile application through smart phone camera. Based on reduction in wound size healing rate was assessed. Digital planimetry applications are accurate and precise in wound measurement compare to standard ruler method and tracing method.

The calves presented with abdominal affections requiring surgical interventions were randomly divided into group I and group II with seven animals in each group.  All the animals were premedicated with dexmedetomidine at 2 µg/kg body weight, pentazocine at 1 mg/kg body weight and midazolam at 0.2 mg/kg body weight intravenously. In group I and group II, anaesthetic induction was carried out with propofol at 2 mg/kg body weight and etomidate at 0.25 mg/kg body weight intravenously, respectively. Both the groups were maintained in Isoflurane anaesthesia with modified oro-endotracheal tube. The cardiovascular parameters such as heart rate, mean arterial blood pressure, systolic and diastolic blood pressure were monitored during different stages of anaesthesia in both the groups. In both the groups, a significant decrease in heart rate was noticed after premedication and anaesthetic induction. A Significant increase was noticed in systolic blood pressure values after anaesthetic induction and 10th minute of anaesthesia in group I and a highly significant increase was noticed after induction up to 10 minutes in group II.  A highly significant increase in diastolic blood pressure was noticed after induction and 10th minute in group I, whereas significant increase was noticed in mean arterial pressure after induction and 15th minute of anaesthesia in group II animals. The cardiovascular parameters recorded in the present study concluded etomidate produced better cardiovascular stability and minimal respiratory depression compared to propofol throughout the anaesthetic period.
