ArticleItem Open Access Aswagantha (Withania somnifera) churnam supplementation in feed on production parameters, serum lipid and liver enzyme profile of desi fowl(2020-01) Vadivoo, VS; Lakshmikantan, U; Mangalagowri, A; Mathivanan, R; Baskaran, D; TANUVASThis study was conducted to record the effect of Aswagantha (Withania somnifera) churnam supplementation in feed on production parameters, serum lipid and liver enzyme profile of desi fowl. The experiment was conducted for a period of 4 months in 150 desi fowl (Namakkal Chicken I). The chicks were divided into three treatment groups containing 2 replicates in each group except control group. The dietary treatments included Group 1 (Control) without any herbal supplementation, Group 2 - 1.0% and Group 3 with 0.5% ashwagandha churnam. Results showed that supplementation of 0.5 percent aswagantha churnum in the feed increased body weight gain, feed conversion ratio and majority of the lipid biochemical profile and higher concentration of aswagantha churnum (1 percent) increased the burden on liver function. So supplementing 0.5 percent aswagantha churnam is beneficial for the increasing body weight and to reduce the blood cholesterol and triglycerides in desi fowl.ArticleItem Open Access Dietary Inclusion of Organic Chromium on Production and Carcass Characteristics of Broilers(2006) Anandhi, M; Mathivanan, R; Viswanathan, K; Mohan, B; TANUVASAn experiment was conducted to study the influence of dietary organic chromium on production and carcass characteristics of broilers for a period of six weeks with one hundred and twenty eight commercial, straight run day-old broiler chicks. These chicks were randomly grouped into four treatments with four replicates of eight chicks each. The treatment groups consisted of basal diet (T1), 250 (T2), 500 (T3) and 750 (T4) μg organic chromium per kilogram basal diet. The results revealed no significant difference in body weight gain, feed consumption, feed conversion ratio, and livability between treatment groups from first week to the end of the experimental period. The carcass yields did not differ between treatment groups. The abdominal fat-pad thickness was significantly (P<0.05) reduced in chromium-supplemented groups. However, moisture and ether extract content of breast and thigh muscle did not differ significantly between the treatment groups. However, the breast and thigh muscle protein levels were significantly (P<0.05) increased in 500 and 750 μg organic chromium supplemented groups compared to control. Breast and thigh muscle cholesterol was significantly lower (P<0.05) in chromium-supplemented groups as compared to the control group. Based upon the study, the supplementation of organic chromium in broiler ration did not improve the production performance. However, it may be used to produce lean meat.OtherItem Open Access EFFECT OF ‘Pro Sync – NF’ DERMAL PATCH IN ANESTRUS CATTLE(2019-12) Lakshmikantan, U; Vadivoo, VS; Mathivanan, R; TANUVASEffect of ‘ProSync – NF’ dermal patch in estrus induction among anestrus cattle was studied. Pluriparous cows (n = 7) with the signs of post-partum anestrus were selected for the study. On rectal examination, one animal was not having corpus luteum in both the ovaries (true anestrum) while the other six animals had corpus luteum (false anestrum). All the seven animals were affixed with the ‘ProSync – NF’ dermal patch (coated with nano progesterone) for five days. Except for the case of true anestrum, all the other animals were administered with Cloprostenol sodium (250μg) on the day of patch removal (Day 5). Six (85.0%) out of seven animals (including the cow with ovarian inactivity) evinced estrus after the treatment. Out of six, four (66.0%) and two (44.0%) animals showed estrus 72 hours and 120 hours after patch removal, respectively. All the six animals were inseminated with frozen semen. All the animals were subjected for pregnancy verification by 60 days post-insemination by rectal examination and it was found that four (66.0%) out of six animals were pregnant. Out of the seven animals treated with ‘ProSync – NF’ dermal patch, four cows (57.0%) conceived which is indicative of fertile estrus induction at the first service. Hence it could be concluded that ‘ProSync – NF’ dermal patch could be effectively used to induce the estrus in anestrus cows.ArticleItem Open Access Feeding of Fermented Soybean Meal on Broiler Performance(2006) Mathivanan, R; Selvaraju, P; Nanjappan, K; TANUVASSoybean meal was fermented with Aspergillus niger for 48 h, dried and supplemented in the broiler diet at 0.5, 1.0 and 1.5 percent to study its effect on production performances and intestinal characteristics by using 200 day-old Vencob broilers for 6 weeks period and compared with control diet and commercial enzyme preparation. The result revealed that there was no difference in body weight between treatments up to 4th weeks of age. However, body weight of 0.5 percent FSM fed group was significantly (P< 0.05) higher than control at 5th and 6th weeks of age. The cumulative feed consumption was significantly (P< 0.05) lesser in 1.5 percent FSM group at 5th and 6th weeks of age. During 3rd and 4th weeks, 0.5 percent FSM fed group recorded better (P< 0.05) FCR than other groups. The livability was 100 percent in all the treatment groups. The percentage of intestine, pancreas, ready-to-cook weight to live weight, intestine length and viscosity of intestinal content were not significantly differed between the treatments. However, the pH of intestinal content was significantly (P< 0.05) lower in 0.5, 1.0 percent FSM and commercial enzyme supplemented groups as compared to control. The ileum villi length and width was significantly (P< 0.05) higher in 0.5, 1.0 FSM and commercial enzyme supplemented group compared to control. The activities of digestive enzymes did not differ significantly between treatments except lipase activity where, the lipase activity was significantly (P< 0.05) higher in 0.5 percent and 1.0 percent FSM than other groups. It was concluded that fermented soybean meal may be supplemented in broiler diet at 0.5 percent level as microbial enzyme supplement to improve the production performance of broilers.ArticleItem Open Access Field Survey on Extent of Adoption of Improved Dairy Husbandry Techniques in Erode District of Tamil Nadu, India(2020-04) Geetha, T; Tensingh Gnanaraj, P; Lakshmikantan, U; Mathivanan, R; Manokaran, S; TANUVASThe present study was carried out in Erode district of Tamil Nadu to find out the extent of adoption of improved dairy husbandry techniques. A random sample of 300 dairy animal owners were selected and extent of adoption of improved dairy husbandry techniques in six major aspects of housing, feeding, breeding, health care, milking and calf rearing management was studied. Proper orientation of animal shed and housing in separate located place were more adopted in housing techniques. Provide clean and fresh drinking water, feeding balance concentrate mixture on the basis of milk production was more adopted in feeding management. Keeping watch on oestrus cycle and heat symptoms, service/insemination after 12-16 hours since onset of heat and artificial insemination of animals were more adopted by the dairy animal owners. Timely and regularly vaccination and observing animals daily for signs of sickness were more adopted. Hygienic milking and calf rearing techniques were more adopted by the dairy animal owners.ArticleItem Open Access Hematological and serum biochemical parameters of broilers fed with Andrographis paniculata as an alternative to antibiotic growth promoter(2012-11) Mathivanan, R; Edwin, SC; TANUVASAn experiment was conducted to study the effect of Andrographis paniculata on hematological and serum biochemical parameters of broilers as an alternative to antibiotic growth promoter with one hundred and fifty commercial, one day-old broiler chicks. The chicks were fed basal diet (T1), basal diet with 20 mg/kg virginiamycin (T2), basal diet containing A.paniculata-1.0 g/kg (T3), basal diet containing A.paniculata-2.0 g/kg (T4) and basal diet containing A.paniculata - 3.0 g/kg (T5) and were maintained for six weeks period. The result revealed that the packed cell volume were ranged from 29.66 to 32.83% and hemoglobin levels ranged from 12.16 to 13.06 g/dl which did not vary significantly between treatment groups. The total leukocyte count was significantly higher in T5 compared to control group with no difference between the levels of A. paniculata. The serum total cholesterol and high-density lipoprotein (HDL) cholesterol levels in A. paniculata fed group did not vary significantly from virginiamycin and control groups. A. paniculata fed group had significantly higher serum total protein, albumin and globulin than virginiamycin and control diet fed groups. The serum glucose level did not vary between treatment groups than antibiotic and control diet fed groups. Serum aspartate transaminase, alkaline transaminase and alkaline phosphatase were significantly lower in A. paniculata fed groups. It was concluded that feeding A. paniculata improved the immune status and hepatoprotective activity in broilers.ArticleItem Open Access Influence of drinking water sources on egg production performance in commercial White Leghoms(TANUVAS, 2000) Mathivanan, R; Sundaresan, K; Mani, K; TANUVASlWenty commercial White Leghorn layer farms in and aroWld Namakkal area, which were getting drinking water either from bore well or open well were selected for this study. Water samples were collected at two weeks interval for 20 weeks period and analysed. The results revealed that except the sulphate and total dissolved solids, chloride, nitrate, nitrite and total hardness were comparatively higher in open well tJum bore well water. Though the open well water had higher level ofsalts, the salt levels in both the water sources\ were within the safer level except nitrite. Bore well water given layers recorded betterHDEP, HHEP and feed efficiency when compared to layers getting water from open well. It is concluded that in Nama1dcal poultry pocket layer farms with bore well water perfonned better than the layer farms with open well water as drinking source.ArticleItem Open Access Microbial lipase production in poultry feed ingredients(Indian Poultry Science Association, 2006) Mathivanan, R; Saravanan, T; Sabareeswaran, A; Selvaraj, P; Nanjappan, K; TANUVASRhizopus oryzae was grown on fermentation media containing maize flour, soyabean meal and de-oiled rice bran with or without emulsified olive oil at 30oC. The lipase enzyme activity and total protein concentrations of fermentation media were determined at 24, 48, 72 and 96 h of fermentation. The results revealed that soybean meal produced high lipase activity at 72 h of fermentation compared to de-oiled rice bran (DORB) and maize flour. Addition of olive oil to fermentation media increased the lipase production in all the fermentation media. The total protein assay revealed that soybean meal was having more protein in all fermentation periods compared to DORB and maize flour.ArticleItem Open Access OBSERVATION ON TOXIC EFFECT OF LEVAMISOLE IN SMALL RUMINANTS(2002) Thilakan, N Jeya; Karunakaran, P; Mathivanan, R; Karunanithi, K; TANUVASLevamisole is a broad spectrum imidazothiazole group of anthelmintic as well as immuno-stimulant commonly used against gastro intestinal nematodes of domestic and wild animals. It acts selectively as agonist at synaptic and extra synaptic nicotinic acetylcholine receptors on nematode muscle cells and produce contraction and spastic paralysis (Martin_ 1997).ThesisItem Open Access Panchagavya And Andrographis Paniculata As Alternatives To Antiobiotic Growth Promotants In Broiler Production(Tamil Nadu Veterinary and Animal Sciences University, 2006) Mathivanan, R; TANUVAS; Edwin, S.CArticleItem Open Access Production Performance and Carcass Traits of Broilers Fed with Sunflower Acid Oil(2006) Jayalakshmi, NS; Mathivanan, R; Amutha, R, et al.,; TANUVASThe influence of sunflower acid oil (SFAO) usage on production performance, carcass traits and economics of broilers were studied. SFAO was analyzed for its ME value by conducting metabolic trial and result revealed that the AME and TME value of SFAO were 4.398 and 4.453 kcal/g, respectively. The feeding trial was conducted by using two hundred commercial, straight run day-old broiler chicks. These chicks were randomly grouped into five treatments with four replicates of ten chicks each and fed basal diet (T ), basal 1 diet with 1 (T2), 2 (T3), 3 (T4) and 4 (T5) percent of SFAO for a period of six weeks. The results revealed that there was no significant difference in body weight gain, cumulative feed consumption, cumulative feed conversion ratio and livability between treatment groups from first week till the end of the experiment. The carcass yield, abdominal fat pad weight and thickness also did not differ significantly between treatments. Inclusion of SFAO at 1, 2 and 3 percent in broiler diet increased the net profit per kg live weight by 2.8, 1.8 and 3.7 percent, respectively as compared to control group. It was concluded that 3 percent SFAO can be safely included in broiler diet without affecting production performance with increase in net profit per kg live weight.ArticleItem Open Access Study on Effect of Different Weaning System on Carcass Characteristics of Tellicherry Goat(2020-05) Geetha, T; Tensingh Gnanaraj, P; Lakshmikantan, U; Mathivanan, R; Manokaran, S; TANUVASTo study the effect of different weaning systems on carcass traits of Tellicherry goats 42 Tellicherry kids were allocated to three treatment groups viz. Group 1- Late weaning (at three month); Group 2- Mid weaning (at two month) and Group 3- Early weaning (at one month). Different weaning system had non-significant (p>0.05) effect on pre-slaughter weight, empty live body weight, carcass weight, dressing percentage and carcass length. Dressing percentage in Tellichery goat was 38.66±0.66 % irrespective of weaning system. Leg portion (33.53±0.66%) contributed the highest proportion followed by breast and shank, rack, neck, shoulder, loin and flank. There was no significant difference (p>0.05) between treatments in weight of edible and non-edible offals. Among non-edible offal, hide had the highest proportion (8.78±0.31%) on pre-slaughter weight basis.
