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. 

In the present study, the expression pattern of OAS-1 and MX-2 gene in peripheral blood mononuclear cells (PBMC) was associated with the early pregnancy in cattle. A total of 60 animals were selected and divided into 2 groups, treatment (50) and control (10) group and synchronized using double PGF2α protocol by 11 days apart followed by insemination at 72 and 96 hrs after second dose of PGF2α. The cows were subjected to blood collection on day 0, 14, 18, 20 and 25 post insemination and Peripheral Blood Mononuclear Cells (PBMC) were harvested using Histopaque® solution, followed by RNA isolation and cDNA synthesis. A significantly (P≤0.01) higher expression of OAS-1 and MX-2 gene was observed on days 18 and 20 post oestrum by quantitative real-time PCR and concentration of MX-2 protein in serum were significantly higher (P≤0.05) on day 18, 20 and 25 in pregnant cows when compared with that of non-pregnant cows. Hence, the present study is concluded that the expression of OAS-1 and MX-2 genes and their encoded proteins may be used to develop a marker for early pregnancy diagnosis in cattle.

Antiviral activity of ivermectin was examined against R2B strain of Newcastle disease virus in 9 - day old embryonated chicken eggs. Five distinct concentrations (500, 250, 100, 50, 10 µg/mL) of ivermectin were used in the study. Haemagglutination test was performed to determine the antiviral activity of ivermectin by using chicken RBC. The results revealed that ivermectin can exert a significant antiviral activity against Newcastle disease virus at higher concentrations (500, 250 and 100 µg/ml) but with cytotoxic effects. On the contrary a moderate to weak antiviral activity without cytotoxicity was demonstrated at lower concentrations (50, 10 µg/ml).

A study was conducted to optimize the level of finger millet (Eleusine coracana) powder as a thickening agent in the chicken soup prepared with no added oil. Whole finger millet (FM) was powdered finely and used as thickening agent in chicken soup at 0 (control) 5(FM5), 10(FM10) and 15(FM15) parts levels. The pH significantly decreased with increase in the finger millet level where it was highest in control and lowest in FM15. In the sensory evaluation, appearance, flavour and mouth feel scores significantly decreased with increase in finger millet level. The consistency scores were significantly higher for the treatments with finger millet compared to control. The overall acceptability scores were comparable among the control, FM5 and FM10 treatments and significantly lower for FM15. Hence, from this study, it can be concluded that finger millet might be efficiently utilized as a thickening agent in chicken soup up to 10 parts level, which would fortify the nutritive value.

The research on Integrated Farming System (IFS) was conducted from 1987 onwards at Tamil Nadu Agricultural University, involving different components (Jayanthi and Balusamy 2017). The IFS is an integrated resource  management strategy for obtaining economic and sustained crop and livestock production and preserving the  resource. It also includes capturing the new market opportunities through enterprise including post-harvest / value addition, from Low value to High value crops, from Water Loving crop to Water Saving crop, from Single crop to Multiple crop. The impact of technology of improved farming system: Productivity, Economic return, Energy input-output, Employment, Equity (gender issue) and Environment. This paper focuses on the development of Integrated Farming System (IFS) and its impact on the economy of agriculture, animal husbandry and standard of living of the farmers of the country as a whole.

Obstructive urolithiasis is a serious and potentially fatal condition in male small ruminants. It is caused by obstruction of urethral lumen at the distal portion of the sigmoid flexure and at the urolithic process. The aim of this study was to evaluate the efficacy of surgical tube cystostomy in the management of obstructive urinary calculi in male sheep and goat. A total of 6 animals were studied (sheep-2 and goat-4) that were referred to Large animal clinics - Out Patient- Surgery Unit of Madras Veterinary College Teaching Hospital with a history of anuria, dysuria and stranguria. In Tube cystostomy, the animals were positioned in right lateral recumbency. The bladder was approached in left paramedianregion cranial to the last pair of rudimentaryteats. The urine was drained and calculi in the bladder was removed with the forceps. The catheter was fixed in the urinary bladder by meansof purse string suture pattern using 3/0 or4/0 polyglecaprone. Then the abdominal muscles and skin were apposed. Biochemical analysis revealed significant increase in BUN & Creatinine pre-operatively and decreases post operatively. Postoperatively normograde contrast cystourethrography on day 1 revealed filling defect of contrast agent showing obstruction at the level of Sigmoid Flexure. Ultrasonographic examination after normal urination revealed presence of calculi and also the site of obstruction in the bladder. The time period taken to return for normal urination in Tube Cystostomy was (10.66 ± 0.06 days) and the wound healing of the surgical site was better in tube cystomy.

Displacement of the abomasum is one of the important incidence recorded in dairy cattle especially after calving that lead to huge economic loss. A six year old Holstein Friesian female cow calved fifteen days back was presented to the Large Animal Outpatient Unit, Teaching Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of not voiding dung and anorexia for past three days. The animal was fed with corn and ragi feed. Clinical examination revealed pale pink mucous membranes, right side distension of abdomen, ping sound on right paralumbar fossa to 11th intercostal space on simultaneous auscultation and percussion. On rectal examination balloon like structure was noticed and the liptak test revealed pH of 2. Ultrasonographic examination of abomasal contents and post mortem examination confirmed RDA.

Canine oral papillomatosis is a contagious and spontaneously regressing benign neoplastic disease of young dogs caused by canine oral papillomavirus. Six dogs of different breeds aged between 1-3 years were presented to Veterinary Clinical Complex with the history of wart like lesions in different parts of the oral cavity. Under Xylazine sedation and 10 % Lignocaine spray representative biopsy sample of wart was surgically excised. Autogenous vaccine was developed and mixed with formalin solution to in activate the virus. Dogs were subjected to inj. Autovaccine 1 ml through subcutaneous route once in a week for 5 weeks. Warts were completely regressed within 4 weeks period after autoimmune therapy. There was no recurrence of papillomatosis among the treated dogs during the follow-up period of 6 months and no adverse effects were recorded.

A primiparous Holstein Friesian crossbred cow was brought to VCC, VC&RI Namakkal with ventral swelling. Based on rectal examination and abdominal palpation it was diagnosed as right sided uterine torsion with prepubic tendon rupture. After the fetal delivery by caesarean section and proper postoperative care is given for a period of 10 days, life of the dam was saved.
