Conventional open thyroidectomy is often associated with post-operative complications including nerve damage, voice disturbances, paraesthesias, adhesions and prominent scarring. Several endoscopic surgical techniques have been reported as alternatives to conventional thyroidectomy. Natural orifice transluminal endoscopic surgery is a promising approach which leaves no scar, produces few complications and affords faster discharge from care. Several studies have explored its utility in total thyroidectomy in patients with benign or malignant thyroid disease. Herein, we present a case series on the successful application of transoral endoscopic total thyroidectomy vestibular approach (TOETVA) in benign and malignant diseases of the thyroid. We performed TOETVA in 11 patients presenting with benign or malignant thyroid nodules in our hospital, between 1st January 2015 and 30th June 2016. The surgery was completed successfully in all patients with a pre-operative diagnosis of multinodular goitre. The surgery was performed under general anaesthesia and the mean operative time was 130 min. The mean blood loss was 2–3 cc. No incidence of recurrent laryngeal nerve injury, damage to mental nerve, parathyroid damage or peri-incisional adhesion occurred in the study participants. No visible scarring occurred in the patients following surgery. The patients had an uneventful recovery after the surgery and were discharged after 4 days. TOETVA is safe and effective in the surgical management of multinodular goitre and offers a scar-free alternative to conventional surgery.
Aim: To assess the reproductive performance and managemental advantages of Artificial Insemination of swine. Materials and Methods:Large White Yorkshire sows were grouped into two batches (10 each) for AI and natural mating. AI 9 group was given two inseminations with semen extended with Beltsville Thawing Solution (BTS,3 x 10 spermatozoa per dose), at standing heat. Similarly, for natural mating group, triple mating was followed. The reproductive performance was studied after maintaining the sows under optimal managemental conditions. Results:The results indicated that AI and natural mating practices showed 100% conception rate. The litter size of AI group was 8.36±0.28 and that of the natural mating group was 10.6±0.64, that varied with high significance. The still birth rate was 0.7±0.26, which was significantly higher in natural mating group. The pre-weaning mortality was 4.34% and 7.5% for AI group and natural mating group respectively. The time consumed during mating per sow also varied highly significantly which was 11.46±0.47 minutes and 51.2±2.08 minutes for the AI group and natural mating group respectively. Conclusion:It was found that AI was found to be time and labor saving. The reduced litter size in AI group could be improved by ensuring that inseminations occur at an optimum time resulting in a high farrowing rate and litter size. AI can be successfully introduced in field conditions with some fine tuning.
Background: The COVID-19 pandemic and subsequent lockdown have created unprecedented emergency and sudden distress on all sectors in India including the livestock sector. Among livestock sectors, dairy farming is more sensitive due to the handling of an essential and perishable commodity of milk.Methods: Under this pandemic situation, the aim of the study to know the constraints confronted and management practices followed by dairy farmers during the COVID-19 pandemic situation. The study was conducted in July 2020 in Cuddalore district of Tamil Nadu. Thirty dairy farmers were selected randomly and data were collected by a personal interview method through a well-structured interview schedule. Socio-economic data were analyzed by statistical methods viz. percentage, mean and standard deviation. Constraints of dairy farming were analyzed and ranked by Mean Weighed Score method and percentage analysis was used for analyzing and ranking management practices.Result: Socio-economic characterstics revealed that more than 86.66 per cent of dairy farmers were belonged low to medium groups and utilized different mass media tools for retrieving information. The constraints analysis revealed that high cost of concentrate feed foremost constraint with Mean Weighed Score of 50.00 were ranked first. Dairy farmers expressed difficultly in the procurement of concentrate, shortage of wheat bran supply and elevated wheat bran cost (MWS 44.44) second important constraints. Dairy farmer’s made alterations in the concentrate feed composition, consulted veterinary doctors over the phone and direct selling of milk as management practices to manage the pandemic situation.
Aim:To identify the suitable roofing pattern for dairy cattle in North East Zone of Tamil Nadu, India, based on micro climatic conditions.Materials and Methods:Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were selected. Temperature and temperature humidity index (THI) were recorded using the maximum-minimum thermometer and digital thermo-hygrometers. The study was conducted for 1 year covering four seasons namely South West monsoon (June-August), North East monsoon (September-November), cold season (December-February), and summer season (April-May). The data were statistically analyzed using statistical package SPSS 17.Results:Animal shelters with cement sheets recorded the highest temperature (26.71±1.13°C) and THI (77.23±1.76) at 8.00 am, whereas the lowest temperature (24.83±1.17°C) and THI (74.54±1.72) were recorded in the thatched shed. There was significant difference (p<0.01) in temperature and THI at 8.00 am during South West monsoon and North East monsoon seasons between the housing types. During cold and summer seasons, there was no significant difference (p≥0.05) in the environmental variables among various shelter systems.Conclusion:Thatched housing is found to be the suitable one with respect to the climatic variables, followed by tile roof and metal roof. The cement sheet roofed housing is found to be the most unsuitable one in the region for dairy cattle.
SummaryIndividual increase in inbreeding coefficients (ΔFi) has been recommended as an alternate measure of inbreeding. It can account for the differences in pedigree knowledge of individual animals and avoids overestimation due to increased number of known generations. The effect of inbreeding (F) and equivalent inbreeding (EF) calculated fromΔFi, on growth traits were studied in Nilagiri and Sandyno flocks of sheep. The study was based on data maintained at the Sheep Breeding Research Station, Sandynallah. The pedigree information and equivalent number of generations were less in Sandyno compared with Nilagiri sheep. The average F and EF for the Nilagiri population were 2.17 and 2.44, respectively and the corresponding values for Sandyno sheep were 0.83 and 0.84, respectively. The trend of inbreeding over years in both the populations indicated that EF was higher during earlier generations when pedigree information was shallow. Among the significant effects of inbreeding, the depression in growth per 1 percent increase in inbreeding ranged from 0.04 kg in weaning weight to 0.10 kg in yearling weight. In general, more traits were affected by inbreeding in Nilagiri sheep, in which greater regression of growth traits was noticed with F compared with EF. Higher values of EF than F in earlier generations in both the populations indicate that EF avoided the potential overestimation of inbreeding coefficient during recent generations. In the Sandyno population, the magnitude of depression noticed among growth traits with significant effects of inbreeding was higher. The differences in response to F and EF noticed in the two populations and possible causes for the trait wise differences in response to F and EF are appropriately discussed.
Aim: A trial was conducted to assess the influence of parasitic load on the lambs reared under the intensive system, continuous grazing, and rotational grazing systems of management. Materials and Methods: A total of thirty numbers of the undetermined breed of ewe lambs around 4-5 months of age were randomly selected and allotted to three treatment groups: T1 (intensive system - control), T2 (rotational grazing), and T3 (continuous grazing). The T1 group lambs were raised under a stall-fed system of management, the T2 group lambs were grazed under rotational grazing strategy in four paddocks of plot-A, while the T3 group lambs were continuously grazed in plot-B. Results: At the end of the study, there was a highly significant difference (p=0.01) in the fortnightly strongyle egg count per gram (EPG) of feces among the lambs pertaining to the three treatment groups; the lambs in T3 had a higher strongyle EPG compared to T2 lambs. With regard to the overall reduction in EPG from the initial count, lambs under rotational grazing showed the maximum decrease of 54.52% compared to lambs under T3 (continuous grazing). There was a strong positive correlation noticed between the mean temperature of the day at each fortnight and the subsequent EPG at each fortnight with R2=0.87. There was a strong positive correlation noticed between mean FAMACHA® scores and the EPG with R2=0.84, R2=0.83, and R2=0.83 for T1, T2, and T3, respectively. Conclusion: The grazing management with pasture rotation should be considered as a viable option for sustainable parasitic control in case of grazing-dependent livestock husbandry in India.
