    Effect of garlic (Allium sativum) and nilavembu (Andrographis paniculata) on growth performance and cost effectiveness of broiler chicken
    (2019-11) Arify, Toryali; Ezhil Valavan, S; Varun, A, et al.; TANUVAS
    The biological experiment was conducted to study the effect of feeding garlic (Allium sativum) and nilavembu (Andrographis paniculata) in broiler chicken (Vencobb 400) for a period of 6 weeks on various parameters, viz. biweekly body weight, gain in body weight, feed conversion ratio, livability and the cost effectiveness of feeding garlic and nilavembu. A total of 300 day-old, unsexed, broiler chicken were utilized for this study. The treatment groups were fed with diets containing garlic and nilavembu at different levels, such as control (T1), 5 g garlic + 1 g nilavembu (T2), 10 g garlic + 1 g nilavembu (T3), 5 g garlic + 2 g nilavembu (T4) and 10 g garlic + 2 g nilavembu (T5), respectively. Biological experiment revealed that there was highly significant (P<0.01) difference in body weight and body weight gain and feed conversion ratio. No significant difference was observed in feed consumption and livability. The cost effectiveness of the broiler chicken fed with various levels of garlic and nilavembu showed increased net profit per kg live weight in the group fed with 10 g garlic and 2 g nilavembu (T5).

    Progesterone impregnated intra-vaginal device and timed artificial insemination (TAI) on fertility in repeat breeding Jersey crossbred cows
    (2019-08) Sarath, T; Joseph, Cecilia; Veeramani, P, et al.; TANUVAS
    Interest in bovine infertility increased with the introduction of artificial insemination in the 1950s and as the factors involved became known to farmers, herdsmen physiologists and other workers (Roberts 1956). The causes of infertility in bovine are many and can be complex (Arthur 1982) and they relate to Graafian follicle development and maturation, estrus onset, successful coitus, ovulation, fertilization, implantation, development and delivery of the fetus and its membranes. Anything that interferes with these routines makes the animal infertile (Osmanu 1979). One calf from cow per year is the reproductive objective for dairy animals. Nevertheless, this is not always attained and cows must be re-inseminated during several consecutive cycles. In this context appears the Repeat Breeder Cow syndrome (RBC), comprising a heterogeneous group of subfertile cows, without anatomical abnormalities nor infections, that exhibit a variety of reproductive disturbances in a consistent pattern during the course of 3 or more consecutive estrous cycles of normal duration (17–25 days).

    On-field sporting traits and behaviour of indigenous cattle breeds in sporting events (jallikattu) of Tamil Nadu
    (2019-12) Priyadharshini, R; Gopinathan, A; Karthikeyan, SMK; Richard Jagatheesan, PN; TANUVAS
    The on-field sporting traits and behaviours in bull baiting (jallikattu) were recorded in 857 sporting bulls in Madurai and Trichy districts. The overall mean velocity, stride length, time spent within the boundary of fighters and time taken to get tamed of the sporting bulls were 11.77±0.17 m/s, 7.07±0.09 m, 12.76±0.51 sec and 4.90±0.22 sec respectively. Overall on-field sporting behaviours like laterality, hooking, jumping, kicking and agonistic behaviour were 30%, 16.8%, 24.9%, 15.3% and 10.50% respectively. The event of winning and losing, and place of event had highly significant effects on velocity of sporting bulls. Place of event was found to affect the stride length significantly. There was a highly significant effect on laterality, hooking and agonistic behaviour among the winning and losing bulls. Presence or absence of hooking behaviour had highly significant effect and it was more prominent in winning (19.3%) than in losing (11%) bulls.

    Seroprevalence of Mycoplasmosis in Goats of North West Agroclimatic Zone of Tamil Nadu in Organised and Unorganised Sector
    (2019-11) Rishikesavan, R; Palanivel, KM; Saravanan, S, et al.; TANUVAS
    244 serum samples from unorganized sector and 122 serum samples from organized sector were collected from apparently healthy goats of different age and sex from North Western agroclimatic zone of Tamilnadu (India) and were screened for Mycoplasmal antibodies by employing Indirect Enzyme linked Immunosorbent Assay. Sixty two out of 244 serum samples from unorganized goat farms in five districts were found positive which indicating overall seroprevalence of 25.40. Out of 122 serum samples from organized goat farms 35 samples were positive for Mycoplasma infection with percent positivity of 28.68. The Indirect Enzyme linked Immunosorbent assay for Mycoplasmal antibodies detection was found to be simple, reliable with having high sensitivity and specificity.

    A Study on the Factors Influencing the Rate of Learning and Adoption of Technologies by the Livestock Farmers of Ramanathapuram District, India
    (2019-11) Vijayalingam, TA; Rajesh, NV; Ilavarasan, S, et al.; TANUVAS
    This paper analyses the factors that are affecting the rate of learning interest and adoption of newer technologies extended through Veterinary University Training and Research Centre, Ramanathapuram, a recently established (June 2013) constituent unit of TANUVAS, by the farmers of Ramanathapuram district. The present study was carried out for a period of 2 years (June 2016 to May 2018). The source of database included, 1) the total number of beneficiaries enrolled themselves for the training, 2) the total turn outs out of the enrolled 3) the total missed outs after their enrolment for the training 4) total beneficiaries attended the training programme without any prior enrolment but as a result of advertisement in regional newspaper, state level magazines, Reliance voice talk messages, TANUVAS mobile apps etc., 5) data on rate of adoption of technologies by different categories of trainees towards new farm establishment and improvement in the already established farms. The analysis revealed that there was a significant improvement in their knowledge after attending two days on-campus training on various farming enterprises. The adoption level was found to be higher among the farmers attending training on country chicken farming, followed by sheep and goat farming. Although female participants showed 100% interest in attending training, none of them started new farm in this district. The adoption level is poor in case of dairy farming, due to huge initial investment and non-availability of green fodder in this district. Overall, young and lesser educated male participants were eager in adopting technologies by starting new farm after attending the training.
