The poultry industry is based on raising fast-growing chickens. In recent decades, several antibiotics have been employed as growth promoters in the chicken industry, but antibiotic use is banned in the poultry industry due to increased antibiotic resistance and negative impacts on human health. Scientists started searching for alternative antibiotic products as antibiotic resistance increased. Probiotics, prebiotics, organic acids, plant extracts, etheric oils, and immunological stimulants are some of the alternatives. In recent years, these products have improved animal performance, increased animal productivity, prevented and controlled enteric infections, and reduced antibiotic use in animal agriculture. Artemisia, which is currently in scattered form in various research papers, and to draw the attention of experts throughout the world to the Artemisia species' untapped potential. Artemisia annua is also known as sweet wormwood, sweet Annie, and sweet annual wormwood (Chinese: qngho). It's a common wormwood species native to Asia's temperate zones. The active ingredient present in the Artemisia genus is Artemisinin, and chemically it contains both volatile and non-volatile constituents. Biological activities of the Artemisia genus include antibacterial, anti-inflammatory, anti-malarial, anti-coccidial, anti-oxidant, and anti-tumor effects. It has positive effects on growth performance, FCR, gut health, immunity, digestibility, and meat quality of broilers. In conclusion, Artemisia annua is the best alternative product for avoiding anti-microbial resistance in the poultry industry without compromising growth and production. This study aims to review the research conducted on the Artemisia genus.

Fodder quality and availability are major determinants in profitable ruminant production system. Tamil Nadu Veterinary and Animal Sciences University and Department of Animal Husbandry, Government of Tamil Nadu and other related institutions promote fodder production through several schemes and projects. Intensive fodder production through promotion of sustainable fodder production model under irrigated condition is one among them. The objective of the present study was to validate the fodder production potential of the ten-cent model for livestock feeding. In livestock farm complex Madhavaram, ten-cent model fodder plot was established with Hybrid Napier grass variety Co (BN) 5 in 4 cents area; fodder maize (African Tall) in 1 cent; fodder sorghum (CoFS 31) in 2 cents; fodder cowpea (Co 8) and Velimasal (Desmanthus virgatus) in 1.5 cents area each; Agathi (Sesbania grandiÀora) and Subabul (Leucaena leucocephala) were cultivated as boundary plantation. Standard agronomical management practices were adopted during the study period (15 months) and fodder was harvested at specified intervals. The total biomass yield realized was 9918 kg. The average yield/cut (kg) of Co5, sorghum, maize, cow pea, Desmanthus and Agathi/Subabul were 1340.0, 264.6, 160.0, 178.0, 71.0 and 98.0 kg respectively. Highest fodder yield was noticed during south west monsoon season (2492.0 kg) followed by north east monsoon season (1796.5 kg) and lowest yield noticed in summer season (1465.0 kg). The total CP and TDN yield (on dry matter basis) of ten-cent model fodder plot, estimated from available standards were 1121.71 kg and 5586.58 kg respectively during the study period. The results of this study revealed that quantity and quality of fodder harvested from the ten-cent model fodder plot can support one cattle or five goats for a year. It is possible to sustain one cow or five goats through fodder production in the ten-cent model fodder plot.

Hepatocellular carcinoma is one of the most common occurring malignancies in the world and has been reported in various species ofanimals including dogs, cats, sheep and pigs. The aim of this study was to assess the ameliorative effects of nanoforms of silibinin and resveratrol on the body weights, feed intake, and water intake of hepatocarcinogenesis induced rats. One hundred and eight male Wistar rats were randomly divided into nine groups and feed intake, water consumption, body weight gains were recorded. The study revealed a significant difference in the feed intake, water intake, body weights in carcinogen group with control and treatment groups.Nano resveratrol and nano silibinin groups effectively ameliorated compared to raw resveratrol and raw silibinin groups there by suggesting their usage in therapy for liver cancer. 

A study was conducted to assess the quality control practices of both physical and chemical methods of evaluation adopted by feed mills in India while procuring the feed ingredients for preparing poultry feeds. Based on physical methods of evaluation of different feed ingredients, 6.4 % of lots were found to be inferior quality out of 2606 lots tested. The results indicated that the moisture content of grains procured during the period from October to December months was high whereas it was low from April to July. The protein content of soybean meal varied from 45.5 to 47.5% while its solubility varied from 72.1 to 83.2%. The rejection of raw material consignments was 7.85 %. The major reasons for rejection included high moisture, low protein, high level of sand amp; silica, adulteration / contamination with foreign materials. the findings of this study emphasis ther sgnificance of strict quality control measures to be adopted to ensure feed and food safety.

An investigation was carried out to assess the nurtional , texture profile, microbial and sensory quality of wafer cones. Refined wheat flour and water, lecthin oil, vegetable fat, baking powder, SMBS (Sodium Meta Bisulphite) were used for the preparation of the wafer cone. Treatments were prepared with casein powder at the rate of 3, 5 and 7 per cent for enriching the wafer cones and control samples were prepared by using refined wheat flour. The quality assessment for moisture, protein and fat was carried out using infrared analyser from NDC technologies. Sensory acceptability was assessed by 9- Point Hedonic Scale and results were analysed statistically.

A Study on the comaprative efficancy of two types of serial collapasible fish traps differning   rear end funnel opening was carried out. With respect to Type-1 trap having rectangular rear end funnel opening and Type-2 trap with elliptical rear end were fabricated. The experiment was carried out in fishing ground one nautical mile off  the coast of mandatam (Lat 09 degree 16.633 'N  long .. 0.79 degree 08.992 ') Feb 2015 to june 2015. significant differnce wasobserved with respect to catch rate of different species caught irrespective of the design of traps (Plt;0.05). The difference in shape of rear funnel opening was found to be responsible for the significant difference in the catch rear funnel opening was about 3 times higher catch rate of Type-1 trap with rectangular rear funnel opening was about three times higher (17.1 Nos/ soaking day) than that of Type-2 trap with elliptical shaped rear funnel opening (5.9 Nos./ soaking day). The impact of seasonal variation on the catch rate was found to be insignificant (Pgt; 0.05). Though Psammoperca waigensis was found to be the dominant specices in both  types of traps in terms of number, Epinephalus coioides ranked first in term  of weight and price per kilogram in both Type-1 and Type-2 traps. Irrespective of the types of traps tested, the higher catch rate, including all the species caught, and was observed during the month of February which directly increased the overall catch rate during February month. With respect to the behavior of different species caught in relation to the types of traps tested, Sarcocendrum rubrum was recorded only in Type-1 trap which had rectangular shaped rear funnel opening and Muraena sp was recorded only in Type-2 trap with elliptical shaped rear end of the funnel opening which served like a burrow and hence facilitated the entry of eel. Type -1 trap gave three times higher gross returns than Type-2 trap.

A 3 time calved cross bred Jersey cow with its 20 days old calf was presented to the outpatient medical unit of Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal with the history of anorexia, mild respiratory distress and eruptions on the skin for a period of 10 days. General clinical examination revealed high temperature, anaemia, icteric conjunctival mucous membrane, enlarged prescapular amp; cutaneous lymph nodes, eruptions on the skin and presence of ticks on the body. Fine needle aspiration cytology of pre scapular lymph node and pheripheral blood smear examintaion confirmed theileriosis. Incidentally its 20 days old calf too had similar symptoms. Both the dam and the calf were treated with suitable therapeutic regimen including blood transfusion.

Nasal washings and faecal samples were collected from 110 cows during the period between July 2019 and June 2020 in and around the Orathandu, Cauvery delta zone of Tamil Nadu to document the seasonal prevalence of Schistosoma nasale and Schistosoma spindale. These samples were processed and screened by using the standard parasitological techniques. Out of 110 nasal washings, 23 samples (20.9%) confirmed the Schistosoma nasale infection by the presence of eggs. No faecal samples could be detected positive for Schistosoma spindale infection during the study period

The polymerase chain reaction (PCR) modification that enables molecular diagnosis and detection viable cells from diverse samples is based on the Viability PCR (V-PCR). In this study, we optimized V-PCR using a candidate L. plantarum probiotic strain and the technique performed efficiently in detecting live cells from an admixed suspension of live and dead cells. Application of the V-PCR on different probiotics strains (B. coagulans, L. plantarum and L. fermentum) also revealed a strong positive correlation in its performance across the strains tested even with an admixture of varied concentration of live and dead cells and different dilutions respectively (r=0.93 to 0.98). We obtained five and four commercial probiotics available for humans and animal use respectively from the market and tested for the recovery of total viable bacteria by agar pour plate method and also the count of viable bacteria by V-PCR. All commercial preparations when tested by the pour plate method recovered their listed viable counts except for the probiotic B and F, and C & G revealed lower counts (<1 to 2 log, and <3 to 4 log respectively) than the the manufacturer’s claims.

The present study was performed to test the fertility of commercially procured sex-sorted frozen bull semen straws in crossbred cattle of Thiruvallur district of Tamil Nadu under field conditions. A total of 60 crossbred heifers and 60 crossbred cows were inseminated with sex-sorted semen straws containing 2 x 106 X-bearing, frozen spermatozoa from six different bulls. Early pregnancy diagnosis was performed around 28-30 day post insemination using commercially available kits. The pregnancy rates were 31.67 per cent (19/60) and 30.00 per cent (18/60) in heifers and cows, respectively and were 40.9 (9/22), 30.77 (4/13), 27.27 (3/14) and 18.18 (2/11) between cows in first, second, third and fourth calving, respectively. The mean pregnancy rates between animals inseminated with Jersey crossbred and Red Sindhi sex-sorted frozen bull semen were 30.00±5.0 and 31.25±6.9, respectively. The conception rate was not statistically significant (P>0.05) between the groups. Foetal sex determination at 65-80 days post insemination using ultrasonography confirmed female foetus in all the pregnancies. Hence, the present field trial concludes similar pregnancy rates with the commercially procured X-bearing sex-sorted frozen semen straws in crossbred cattle along with foetal sex determination revealing female foetus in all pregnant animals.
