The objective of the present study is to find out the scope and extent of utilization livestock farm service provided by the Agricultural Technology Information Center (ATIC), TANUVAS, Kattuppakam, Chengalpattu district of Tamil Nadu. The available records for a period of two years from January 2021 to December 2022 were analysed to study the number of farmers visited, and their purpose of visits at ATIC, Kattupakkam. The findings of the study revealed that a total of 1727 farmers visited ATIC, Kattupakkam in which majority (86.21%) respondents were males. Among the specific purpose of visits, purchase of fodder seeds (35.95%) was their high priority followed by purchase of publications (32.42%), farm advisory (13.60%), livestock feed (11.92%) and others (6.07%). On farm advisory, majority were benefited on goat farming (31.66%) than other livestock farming practices. It was concluded that during the study period more than 65% of farmers benefited through the purchase for fodder seeds and publication and around 68% of the livestock farmers were likely to be more specific in their purpose of visits at ATIC, Kattupakkam. 

A total of sixteen commonly available medicinal herbs (different parts) used in Indian traditional medicine were collected. The collected parts were, shade-dried, ground to fine powder and stored in air-tight containers. The samples were analyzed for proximate principles, acid-insoluble ash, gross energy, minerals and fatty acids. Emblica officinalis fruits had significantly (P < 0.05) highest moisture (88.67%), Moringa oleifera leaves had significantly (P < 0.05) highest crude protein (26.99 %), Coriandrum sativum seeds had significantly (P < 0.05) highest crude fibre (32.53%), Syzygium aromaticum buds had significantly (P < 0.05) highest crude fat (18.57 %), Mentha spicata leaves had significantly (P < 0.05) highest total ash (11.53 %), Allium sativum bulbs had significantly (P < 0.05) highest nitrogen-free extracts (90.14 %) and Murraya koenigii leaves had significantly (P< 0.05) highest acid insoluble ash (4.71 %). The gross energy content was significantly (P < 0.05) highest in Coriandrum sativum seeds (4605.33 Kcal/Kg). Azadirachta indica leaves had significantly (P < 0.05) highest calcium (2.99 %), Phyllanthus niruri leaves had significantly highest (P < 0.05) phosphorus (0.53 %), Andrographis paniculata stem and leaves had significantly (P < 0.05) highest copper (41.27 ppm), E. officinalis fruits had significantly (P < 0.05) highest iron (596.78 ppm) and S. aromaticum buds had significantly (P < 0.05) highest manganese (286.96 ppm). C. sativum seeds had significantly (P < 0.05) highest levels of oleic acid (73.76 %), T. foenum seeds had significantly (P < 0.05) highest levels of linoleic acid (36.43 %) and P. niruri leaves had the significantly (P < 0.05) highest levels of linolenic acid (51.78 %) Further studies are needed to quantify other bioactive compounds, to study their antioxidant and antimicrobial properties so that they could be used as alternatives to antibiotics / other drugs for livestock and poultry.

A study was carried out in the month of September, 2022 to know the economics on rearing of indigenous (local) comparative broiler birds at the Poultry Unit of SCS college of Agriculture, Rangamati, Assam Agricultural University, Dhubri, Assam. For the study, day old chicks of indigenous and broiler, 100 numbers each were introduced in deep litter system of management. Broilers were marketed at the completion of 6 th week, while the indigenous birds were kept up to 8 th week and then marketed. Mean body weight was found to be 2082.67±14.85 g and 658.29±3.49 g in the case of broilers and indigenous birds at 6 th week and 8 th week respectively. The feed conversion ratio (FCR) was recorded as 1.64 and 2.29 for broiler and indigenous birds, respectively. The cost of production per kg bird is Rs.114.70 and Rs. 227.90 for broiler and indigenous birds respectively. The net profit calculated in production of broilers and indigenous was Rs. 5100.00 and Rs. 7450.00 respectively. Benefit cost ratio (BCR) in broiler and indigenous bird was found to be 1.22.1.00 and 1.53:1.00, respectively.

An one and half year old Jersey crossbred heifer was presented to the Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of recurrent bloat, copious salivation, severe respiratory distress and abdominal distension. Under local infiltration with 2% lignocaine hydrochloride, trocharization was performed on left paralumbar fossa using trochar and canula to relieve the gas from the rumen. Palpable hard mass noticed in the caudal cervical esophagus and attempt was made to retrieve with the hand through the oral cavity was unsuccessful. Oesophagogram revealed barium stasis on ventral aspect between 4 th and 5 th cervical vertebra. As the obstruction could not be relieved by passing a probang, cervical oesophagotomy was performed and foreign body (Trichobezoar) was retrieved without any complications.

The present study was carried out to optimize the space and height for placement of baited delta traps to lure and kill house flies in Japanese Quail layer unit at Poultry Research Station, Madhavaram, Chennai where birds were raised in Californian caged system. Red acrylic delta traps with Z-9-Tricosene-Fish meal pellet baits were used for the optimization study. Height optimization of placement of traps was estimated by placing the traps at four different heights in poultry units, viz., ground level, 0.3 m above ground level, 0.6 m above ground level and 0.9 m above ground level. The optimal distance for placement of the acrylic delta trap was estimated by placing the traps at four different distances within poultry units, viz., close to each other, 0.3 m distance between two traps, 0.6 m distance between two traps and 0.9 m distance between two traps. Trap height optimization trial results revealed that maximum number of flies were trapped at ground level, followed by 0.3 m above ground level, 0.6 m above ground level and 0.9 m above ground level in the descending order of preference. Trap distance optimization trials revealed that more flies got trapped when the distance between two traps was 90 cm followed by 0 cm, 60 cm and 30 cm distance between traps. Results revealed that house fly delta traps deployed at ground level at a trap distance of 90 cm could be effective in house fly trapping and can play a vital role in integrated house fly management strategies. 

The present study was undertaken to understand the present status of adoption of TANUVAS SMART mineral mixture, viz, complete adoption, partial adoption, discontinuance and rejection and its perceived attributes, namely, relative advantage, compatibility, complexity, observability and trialability using the schedule developed for the purpose and the economic impact. Partial budgeting was done to assess the economic impact of adopting TANUVAS SMART mineral mixture. Personal cosmopolite and personal localite communication channels had contributed majorly to the awareness of the dairy farmers followed by mass media. Majority of the dairy farmers (78%) discontinued the adoption of the innovation. Sixty six per cent of them had medium level of adoption behaviour followed by high (28%) and low (6%) level of adoption behavior. The reasons attributable were that the technology was perceived relatively less advantageous and not observable. However, it was perceived as highly compatible, less complex and trialable. Net income of the dairy farmers had increased by Rs. 2,216.80 per dairy animal per lactation due to the adoption of TANUVAS SMART Mineral Mixture. The status of adoption of TANUVAS SMART Mineral Mixture, its adoption behaviour and change in net income were found to be significantly associated with land holding, area under fodder cultivation, dairy animal possession, extension agency contact and mass media exposure of the dairy farmers.

Selection of breeding bucks is one of the crucial decisions in both organised and field populations for genetic improvement. Using high genetic merit bucks in the breeding programme could improve the overall production of the stock, thereby augmenting the economic sustainability of the rural goat keepers with zero input system of management. Therefore, understanding the effect of non-genetic factors with respect to semen characteristics is of paramount importance among the breeding bucks within a breed for effective breeding management. In this study, a total of 164 ejaculates from six adult Salem Black bucks were analysed to determine the effect of season and order of the ejaculate on conventional semen attributes using linear mixed models with lme4 package in R software. The estimated marginal means for semen volume (ml), sperm concentration (million per ml), mass activity (0 to 5 scale), initial and pre-freeze sperm motility (per cent) were 0.69 ± 0.05, 3253.00 ± 167.00, 4.70 ± 0.09, 81.80 ± 0.002 and 79.43 ± 0.003 respectively. Season had a significant effect (p < 0.5) on all the traits under study except for post-thaw motility, whereas, the order of ejaculation did not influence the traits except mass activity.

The study on the assessment of body weight gain in three indigenous chicken breeds viz., Aseel, Kadaknath and Siruvidai chicken were conducted in five poultry farms of Vendhoni village, Ramanathapuram district. The body weight gain both between the breeds and farms were statistically analysed for a period of 20 weeks. All the five selected farms were distributed with day old (0 Day) Aseel, Kadaknath and Siruvidai chicks (Each 10 Nos) and about 50 kg each of commercial chick mash (Nutrikraft®). The body weight gain was recorded and assessed every week until 20 weeks. Among the three breeds analysed, a highly significant difference (P ≤ 0.01) existed with Aseel breed having higher body weight gain (1.441 kg) followed by Kadaknath (0.887 kg) and Siruvidai (0.737 kg) at 20 weeks of age.  The weight gain recorded during fourth and eighth weeks of age showed a highly significant (P ≤ 0.01) change among all the three breeds. The weight gain of Kadaknath and Siruvidai were highly significant (P ≤ 0.01) during 12th and 16th week of age. Whereas the weight gain in Aseel was found to be non-significant (P ≥ 0.05) in the same period of study. During 20th week, Siruvidai showed highly significant (P ≤ 0.01) change in weight gain and Aseel and Kadaknath showed non-significant (P ≥ 0.05) change.  Overall, Aseel had higher body weight gain than Kadaknath and Siruvidai breeds. All the three breeds were found to be well adapted to the hot and humid climatic condition of this district.

A four-month-old male Labrador retriever puppy was presented to Referral Veterinary Polyclinic, Indian Veterinary Research Institute with the history of anorexia, vomiting, haemorrhagic diarrhoea and signs of hypovolaemic shock. The case was diagnosed as parvovirus gastroenteritis by rapid antigen detection test. Shock was managed by infusion of polyionic isotonic fluid.  Haematological examination revealed severe leukopenia with WBC count of 0.3×10³/µL, which was treated with administration of recombinant human granulocyte colony stimulating factor (Filgrastim) at 5 mcg/kg subcutaneously along with supportive therapy. Dog showed elevated WBC count and improvement in clinical signs after 48 h. Administration of granulocyte colony stimulating factor along with routine therapy enhanced the survivability in canine parvovirus gastroenteritis.

Fracture comprises one of the major surgical cases having serious impinge on small ruminants causing lameness. A retrospective study was undertaken on incidence of long bone fractures in reference to metacarpal and metatarsal in goats. Among 893 cases, 344 (38.5%) cases had fracture. Incidence according to the bone involved; metacarpal (28.4%), metatarsal (22.9%), tibia (15.9%), femur (14.2%), radius and ulna (11%) and humerus (8.13%). Fractures with special reference to the age, sex, nature, type, location in metacarpal and metatarsal were taken for the study. The age of animals with metacarpal fracture ranged from twenty days to 3 years and had a mean age of 9 months whereas metatarsal fracture ranged from one month to 2.5 years and had a mean age of 1.2 years. Out of 176 goats with metacarpal (98) and metatarsal (76) fractures, male goats (65.3%) and (68.4%) were mostly affected than female. Open fractures were 33% whereas closed fractures were of 67%. Fracture due to automobile accident in metacarpal (45.9%) and metatarsal (31.5%) was found to be the most common cause of fracture in goats.
