Ranga; Sathyamoorthy, S.S.; Kothandaraman, P; TANUVASAn experiment was conducted to study the interrelationship between shape and size of eggs with hatchability, chick weight and sex of the chicks. The results of the present study indicated that hatchability is comparable for both oval and elongated shaped eggs. Medium sized eggs hatched significantly (P<0.05) better than small or large sized eggs. Egg weight and chick weight are highly correlated (r=0.556). The shape of the eggs were not found to influence significantly the sex of the chicks.OtherItem Open Access Management of Peste Des Petitis Ruminants - A Case Report(TANUVAS, 2006-06) Narayanan, Rita; Omprakash, A.V.; Gajendran, K; Baegan, SThesisItem Open Access Productive And Reproductive Performance Of Buffaloes In North East Zone Of Tamilnadu(Tamil Nadu Veterinary and Animal Sciences University, 2004) Balusami, C; TANUVAS; Sivakumar, T; Gajendran, K; Arunachalam, S; Radhakrishnan, K.T.A study was conducted to assess the productive and reproductive performance of the buffaloes under field conditions in North East Zone of Tamil Nadu. 250 farmers were selected randomly from large farmers, small farmers, marginal farmers and landless labourers. About 25.2 per cent of the farmers had dairying as their main occupation and about 75 per cent pursued dairying as subsidiary occupation. The literacy level of these farmers was 75.2 per cent. On an average land size holding was 4.35 ± 1.54 acres. The overall means herd size was 6.51. About 54.5 per cent of the farmers were having more than two decades of farming experience. Average annual income of the buffalo farmers per year was Rs.23,781.20. About 82 per cent of the farmers were able to identify the heat and 30 per cent of farmers could diagnose the pregnancy by themselves. About 46 per cent followed natural service and rest followed Artificial Insemination. The buffaloes calved maximum during the month of October (22.5 per cent). All the farmers were found offering concentrate and roughage to their animals. More than 50 per cent of the farmers had open type of house. About 53.2 per cent of the farmer sold their milk to vendor. Vaccination of animals against HS, BQ, FMD (72.2 per cent) was practised.The least squares mean ± S.E. of total lactation milk yield was 555.89 ± 10 kg in non-descript buffaloes and 1140.18 ± 13.87 kg in graded Murrah buffaloes. The least squares mean ± S.E. of mean lactation length was 294.44 ± 89 days in non descript buffaloes and 327.56 ± 0.85 days in graded Murrah buffaloes. A wide variation was observed in fat, SNF, protein and total solids of non-descript buffaloes, (8.03 ± 0.60, 9.85 ± 0.07, 4.23 ± 0.08 and 17.88 ± 0.57 respectively) and graded Murrah buffaloes (7.33 ± 0.57, 9.47 ± 0.07, 4.14 ± 0.08 and 16.80 ± 0.50 respectively).

Spending on food and food products amounts to 21% India's GDP and the population roughly spent 31% of their earnings for food. The importance of this sector to India's economy is more important, based on the fact that his sector continued to perform well, despite thefall in GDP number and poor performance by many other industries in India, during the recession in 2008-09. Among the components of this sector, Poultry industry, is the fastest growing industry in India and has registered a phenomenal average growth rate of 10% in egg production and 15-20% in broiler production during the last few years.ArticleItem Open Access Status of indigenous ducks in Tamil Nadu, India: a traditional perspective(2009) Gajendran, K; Karthickeyan, SMK; TANUVASexcellentnatural habitats for ducks to be adapted under range system of management. There was instability in the trend of duck population over the years. The duck flocks are highlyconcentrated in the paddy (O ryza sativa ) growing and water shed areas of the state because of their nomadic existence. Even though a well recognized breed of layer duck,Khaki Campbell, is available in India, indigenous ducks are preferred by the farmers for ease in maintenance under range system and bigger size of eggs (62 g). The hatchingoperations are still primitive and natural with the total exclusion of artificial incubation. The management of ducklings and adult ducks involved utilization of indigenoustechnical knowledge as practiced from time immemorial. The egg production is found to be between 160-200 eggs per annum. The mean body weights at hatch and at 24 weeks were 36.88 ± 0.70 and 1454.69 ± 29.82 g respectively.The duck flocks are often migrated to nearby districts in search of fresh forage and water resources as each district in Tamilnadu has different cropping patterns and monsoonconditions. Duck plaque is the major disease threat. Despite various development measures, financial constraints of duck farmers, dependency in marketing, migration for freshfeeding resources, lack of timely vaccination against duck plague and lack of preference of duck eggs over chicken are the constraints in the development of this unexploredspecies.ArticleItem Open Access STUDY ON PANCHAKAVYA - AN INDIGENOUS FORMULATION AND ITS EFFECT ON THE GROWTH PROMOTION OF CROSSBRED PIGS(2006-07) Ganesh Kumar, K; Kumaravelu, N; Sivakumar, T; Gajendran, K; TANUVASThis paper deals with the preparation of panchakavya an indigenous formulation consisting of products from cow viz., dung, urine, milk, curd and ghee and its effect on promotion of growth in crossbred pigs.

Among different species of livestock kept by farmers, cattle and buffaloes are maintained by maximum numbers in varying combinations.ArticleItem Open Access Traditional technologies in the improvement of breeds of livestock in Tamil Nadu(2005-07) Karthickeyan, SMK; Gajendran, K; TANUVASAnimal husbandry has been practiced in India since time immemorial. Among different species of livestock kept by farmers, cattle and buffaloes are maintained by maximum numbers in varying combinations. Earlier various methods were used for the improvement of the breeds of livestock. Tamil Nadu is endowed with some recognized breeds of cattle (5), buffalo (1), sheep (8) and goat (1), besides many non-descript domestic animal species. There are certain traditional background in the evolution and existence of these breeds. Selection of animals and planned mating were evolved in earlier days itself. Further, efforts are being made by the farmers to change their sire in the herd / flock for improvement even with out knowing the underlying principles. Indigenous technical know-how used for the improvement of breeds of cattle, buffaloes, sheep and goats and pigs in Kerala have been discussed.
