ThesisItem Open Access ASSESSMENT OF MICROBIAL LOAD AND GASEOUS POLLUTANTS IN LIVESTOCK SHEDS(TANUVAS, Chennai, 2015) Divyalakshmi, D.; TANUVAS; Kumaravelu, N.; Sundaram, S. Meenakashi; Ronald, B. Samuel MasilamoniA study was conducted to assess the air bome microbial status and gaseous pollutants inside the dairy and pig (pig fattener sty and farrowing pen) sheds and to compare the efficacy of commonly used disinfectants inside the livestock sheds. The gaseous pollutants including carbon dioxide, methane and ammonia in livestock sheds were recorded using Multi Gas Monitor (Drager X-am 7000). Microbial load (CFU/ma) including total bacterial count, coliform count and mould count was assessed in the livestock buildings.ArticleItem Open Access ASSESSMENT OF MICROBIAL POLLUTANTS INSIDE LIVESTOCK SHEDS IN AN ORGANISED FARM(TANUVAS, Chennai, 2015-09) Divyalakshmi, D.; Kumaravelu, N.; Ronald, B. Samuel Masilamoni; Sundaram, S. Meenakshi; TANUVASIntensive livestock production is a significant source of microbial air contamination which affects human and animal health.

Serma Saravana; Muthuramalingam, T.; Vanan, Thanga ThamilArticleItem Open Access Effect Of Different Feeding Systems on Back Fat Thickness and Body Measurements in Fattener Pigs(TANUVAS, Chennai, 2021-05) Divyalakshmi, D.; Kumaravelu, N.; Pandian, A.Serma Saravana; Muthuramalingam, T.; Gnanaraj, P. Tensingh; TANUVASPig rearing on concentrate feed may not be economical because of higher market price of raw materials. The alternative source could be the use of swill feeding. Consequently, the impact of the swill feed on the back fat thickness and body measurements calls for investigation against concentrate feeding. Hence in the present study, an attempt was made to compare the body measurements and back fat thickness in fattener piglets which were fed with swill feed vs. concentrate feed. Body measurements were made using measuring tape and back fat thickness was recorded with Lean Meater. By statistical analysis it was found that there was no significant difference in body length, girth and back fat thickness of pigs between the treatments. This indicated that the type of feed has no effect on the body measurements and back fat thickness in fattener pigs.ArticleItem Open Access Evaluation of Chemical Parameters of Drinking Water for Livestock(Indian Veterinary Association, Chennai, 2019-04) Kumaravelu, N.; Vanan, Thanga. Thamil; Saraswathi, S.; Divyalakshmi, D.; TANUVASDrinking water is a vital part of the daily activity of livestock and also an important management aspect in livestock farming. The study was conducted to assess the chemical quality of water for livestock in Vellore district. Water samples were collected from Sholingur (V1) and Kodaikkal (V2) villages from Sholingur block and Manthangal (V3) and Pulianthangal (V4) villages from Walajah block. Samples from tap, bore well, pond, open well and lake were tested to find their suitability as drinking water for livestock. Except nitrate and phosphate content other values were by and large within in the BIS acceptable level.ArticleItem Open Access Floor Cleaning Effect of Herbal Mixture in Cattle and Pig Sheds(Indian Veterinary Association, Chennai, 2019-05) Divyalakshmi, D.; Kumaravelu, N.; Ronald, B. Samuel Masilamoni; TANUVASDisinfection of animal shed means making them free from disease producing organisms. An attempt has been made to assess the efficacy of cow urine – herbal preparation. The study was carried out in three different seasons of the year in pig fattener facilities, farrowing pen and dairy units in an organised farm. Cow urine was used as a base material in this case. The efficacy of the disinfection was found out by dilution method. The action of cow urine based preparation was highly significant (P<0.01) in all livestock sheds. The seasonal effect of the disinfectant may be due to the influence of temperature, humidity (both absolute and relative), sunlight exposure and even atmospheric pollutants.ArticleItem Open Access Mange Infestation in Rabbits with Acorus Calamus Based Preparation(Indian Veterinary Association, Chennai, 2019-06) Divyalakshmi, D.; Kumaravelu, N.; Gnanaraj, P. Tensingh; TANUVASEar mange infestation caused by Psoroptes cuniculi is a very common and widespread problem in rabbit colonies. Psoroptes cuniculi infestation becomes serious, if left untreated. Due to the irrational use of ivermectin, there is decreased ef cacy. To overcome this ill-effect, Acorus calamus based herbal preparation was tried. This was applied for two weeks on alternate days. Three weeks after therapy, improvement was observed which was recorded as dryness of ear lesions, falling of scabs and reduced itching sensationOtherItem Open Access Prediction of Live Body Weight in Nicobari Black Adult Birds(TANUVAS, Chennai, 2018-12) Divyalakshmi, D.; Kumaravelu, N.; Pandian, A.

Reproductive performance of the rams and ewes was recorded through the questionnaire both in migratory and non-migratory flocks. Mean lambing percentage, twinning percentage, livability at birth percentage, age at first mating (months) in ewes, age at first mating (months) in rams, age at first lambing (months) and weaning percentage in migratory and non-migratory flocks were 93.56 and 91.50; 1.87 and 1.52; 98.32 and 98.73; 12.34 and 13.22; 19.64 and 21.44; 18.54 and 19.68; 85.98 and 87.15, respectively. The weaning period for ram and ewe lambs were 2.94+0.96 and 5.03+0.13 in migratory flocks and 4.82+0.13 and 6.06+0.17 in non-migratory flocks, respectively. Reproductive performance of sheep in migratory flocks was significantly better than nonmigratory flocks. The months of October, November and December were main lambing season and the months of April and May were second lambing season.ArticleItem Open Access REPRODUCTIVE PERFORMANCE OF SHEEP IN MIGRATORY AND NON-MIGRATORY FLOCKS IN SOUTHERN TAMILNADU(2014-09) Singaravadivelan, A.; Kumaravelu, N.; Sivakumar, T.; Karthickeyan, S.M.K.; Vinothkumar, D.; Divyalakshmi, D.; TANUVASA study was conducted to analyse the migratory sheep production system in southern agro-climate zone of Tamil Nadu.
