ArticleItem Open Access Ameliorative effects of Phyllanthus niruri on production performance of Guinea fowls raised with aflatoxin contaminated feed(2020) Thanabal, C; Ramamurthy, N; Richard Churchil, R; Tensingh Gnanaraj, P; Preedaa, Manju G; TANUVASThis study was conducted to investigate the effect of aflatoxin and protective role of Phyllanthus niruri herb against the effect of aflatoxin on production performances (Viz. Body weight, Body weight gain, Feed intake, Feed efficiency and Livability) of Guinea fowls. A total of 270 day old keets were divided into six groups (45 chicks each) as following: The T1 Control (without Aflatoxin), T2 (diet with 1 PPM aflatoxin B1), T3 (diet with 2 PPM aflatoxin B1), T4 (diet with 1% herb powder alone), T5 (1 PPM aflatoxin B1 and 1% herb powder) and T6 (2 PPM aflatoxin B1 and 1% herb powder). The results revealed that the inclusion of Aflatoxin B1 (2 ppm) level adversely affected the bodyweight, weight gain and feed efficiency at fortnight during experimental period. Inclusion of 1 ppm aflatoxin B1 in diet does not influence the production parameters. Supplementation of 1 percent Phyllanthus niruri herb powder to control diet caused significant depression in the weekly body weight, Weight gain, feed consumption and feed efficiency. Inclusion of 1 percent Phyllanthus niruri herb powder in the aflatoxin B1 (2 ppm) supplemented diet significantly counteracted the toxin effects of aflatoxin B1 on final body weight, weight gain and feed efficiency at 12th week of age. In conclusion, Guinea fowl production performance was not affected up to 1 ppm level aflatoxin B1 contamination in diet and the negative effects of aflatoxin B1 at 2 ppm level in production performance of Guinea fowls was improved by supplementation of 1 percent Phyllanthus niruri herbal powder on diet.ThesisItem Open Access Dietary Calcium Requirement of Breeder Turkeys in Tropics(TANUVAS, 2010) Sakthivelkumar, K; TANUVAS; Venukopalan, K; Ramamurthy, N; Karunakaran, RArticleItem Open Access EFFECT OF BREED AND SEX ON SERUM BIOCHEMICAL PARAMETERS IN WHITE PEKIN AND INDIGENOUS DUCKS OF TAMIL NADU(2020-04) Kavitha, K; Raj Manohar, G; Vairamuthu, S; Ramamurthy, N; TANUVASThe present work was undertaken to evaluate the effect of breed and sex on Serum Biochemical profile in White Pekin and Indigenous ducks of Tamil Nadu at Post Graduate Research Institute in Animal Sciences (PGRIAS), Kattupakkam. A total of eighty number of ducks comprising 20 male and 20 female each in White Pekin and Indigenous ducks of Tamil Nadu were reared under standard managemental conditions. Once in every 4 weeks, blood was collected from these ducks individually from 20th week onwards for the duration of two months. The parameters such as Total Serum Protein, Serum Albumin, Serum Globulin, Serum Calcium, Serum Cholesterol and Serum Triglyceride were estimated. The results revealed that the White Pekin ducks had significantly (P<0.01) higher Total Serum Protein, Serum Albumin, Serum Globulin while Serum Triglyceride level was significantly (P<0.01)higher in Indigenous ducks of Tamil Nadu. Among sexes, female Indigenous ducks had significantly (P<0.05) higher Total Serum Protein, Serum Globulin than male ducks. Serum Cholesterol and Serum calcium was significantly higher in female White Pekin and Indigenous ducks of Tamil Nadu than the male ducks. Hence, it was concluded that breed and sex had significant effect on Serum Biochemical parameters in White Pekin and Indigenous ducks of Tamil Nadu.ArticleItem Open Access THE EFFECT OF REARING SYSTEM AND MARKETING AGE ON THE PERFORVIANCE OF JAPANESE QUAIL (COTURNIX COTURNIX JAPONICA)(1986) Narahari, D; Ramamurthy, N; Viswanathan, S, et al.,; TANUVASMeat-type Japanese quails were reared on deep litter and in cages upto 10 weeks of age. The relative performance and economics of rearing them uptc 5,6, 7, 8, 9 and 10 weeks of age were studied. Cage rearing had resulted in better body weight gain, feed efficiency, net feed efficiency index and net income over expenditure than litter reared quails.ThesisItem Open Access Hatching Performance of Emu Breeder Birds (Dromaius novaehollandiae)(TANUVAS, 2010) Gangadhar, Chate Amar; TANUVAS; Gnanaraj, P. Tensingh; Kumar, T. Siva; Ramamurthy, NArticleItem Open Access INFLUENCE OF AGE AT DEBEAKING ON THE PERFORMANCE OF JAPANESE QUAILS(1989) Ramamurthy, N; Narahari, D; Thangavel, A, et al.,; TANUVASDebeaking of Japanese quail chicks, at different ages, did not affect significantly (P <0.05) the 6th week body weight, feed efficiency and percentage of livability Hence, debeaking of quail chicks is dispensable, as it had no beneficial effect.ThesisItem Open Access Influence of Age, Sex and Rearing Systems on Expression of Too-Lie Receptors in Native Ducks of Tamil Nadu(TANUVAS, 2012) Kolluri, Gautham; TANUVAS; Ramamurthy, N; Churchil, R. Richard; Raj, G. DhinakarArticleItem Open Access Influence of age, sex and rearing systems on Toll-like receptor 7 (TLR7) expression pattern in gut, lung and lymphoid tissues of indigenous ducks(British Poultry Science, 2014-08) Kolluri, Gautham; Ramamurthy, N; Churchil, R.R.; Raj, G. Dhinakar; Kannaki, T.R.; TANUVASArticleItem Open Access Influence of Egg Size and Shell Colour on Hatchability(TANUVAS, 1984) Prabakaran, R; Narahari, D; Ramamurthy, N; Babu, M; Parivallal, A.V.; Mujeer, K.Abdul; TANUVASThe influence of egg size and shell colour on hatchability parameters of New Hampshire eggs was studied. The results revealed that the eggs weighing 56-60 g showed higher rate of fertility and hatchability. Medium brown eggs had exhibited higher rate of fertility; whereas light brown eggs had recorded better hatchability, with proportionately lower embryonic mortality.ThesisItem Open Access Influence of Nest Box on the Reproductive Performance of Japanese Quail (Coturnix coturnix japonica)(TANUVAS, 2011) Gandhimathi, D; TANUVAS; Babu, M; Ramamurthy, N; Selvakumar, K.N.ArticleItem Open Access SEMEN COLLECTION IN EMU (DROMAIUS NOVAEHOLLANDIAE) BIRD BY NONTEASER METHOD AND ITS MACROSCOPICAL EVALUATION IN HUMID TROPICAL CLIMATE(2015-03) Sundaresam, A; Omprakash, AV; Ramamurthy, N; Subramanian, A; TANUVASA study was conducted for collection and evaluation of emu bird semen by non teaser method. Ten adult male emu birds aged 3 to 4 years were selected and housed individually in a 10’ x 50’ pen constructed in parallel rows at emu unit, University Research Farm, TANUVAS, Chennai, Tamilnadu, India. The male birds were selected based on their readiness in accepting human beings without fear. All the birds were housed properly under standard managemental condition. An Isocaloric and Isonitrogenous standard emu breeder ration was fed to birds and portable drinking water were made available ad libitum. The selected male emus were trained for semen collection by non-teaser method. Out of 10 males, only seven males responded for semen collection. The raw semen collected from individual emu birds was evaluated for macroscopical seminal attributes namely volume, colour, consistency and pH. The overall mean values for volume and pH of individual male were 0.61 0.02 ml and 7.40 0.03 respectively. The individual males showed varied response and significant difference in seminal attributes. Creamy white thick consistency semen had significant (P≤0.01) seminal attributes than yellow and watery semen. The temperament of male emu, sexual behavior and acceptance of the collector and courtship behavior by the male are the key factors for successful training of breeders. This study ensures the possibility of semen collection and facilitate further processing of semen.
