Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Effect of Natural and artificial feeding on growth performance and survival of fry and fingerlings of Clarias batrachus (Linn.)
    (CCSHAU, 2008) Manju Rani; Yadava, N.K.
    Present studies, ten diets (1-10) for the fry and fingerling of magur Clarias batrachus were prepared the with varying protein levels (35, 38, 40, 42 and 45%) were formulated using fishmeal (diet 1-5) and the processed soybean (diets 6-10), as the protein sources. Two hundred fry and fingerlings were randomly released @ 15 per aquaria and then fed for 45 days at 5 percent body weight, per day on the ten experimental diets. Fry and fingerlings were maintained under laboratory conditions (LD 12:12 at 25°C). Studies have revealed that, when live feed is given to fry, then better growth was obtained in comparison to the group fed on the supplementary feed (soybean based) which shows that live feed is the better feed for fry. The studies have further shown that optimum dietary protein levels, which have resulted significantly (P<0.05) with high growth, in terms of live weight and length gain, SGR (% d-¹), growth percent gain, nutrient retention (PER and APD%) and accumulation of carcass protein and fat were observed in the groups, fed on diets containing 4025% protein irrespective of the protein source. Activities at 40.25% dietary protein also support high digestibility and nutrient retention. Studies have further revealed that the growth, nutrient retention and energy retention values were significantly ((P<0.05) high in the group fed on diet containing 40.25% dietary protein from processed soybean (plant based) in comparison with the group fed on diet containing fishmeal (animal based), as the protein source. Postprandial excretory patterns of ammonical nitrogen and orthophosphate production were not affected by the dietary protein quality and quantities, however, fingerlings fed on soybean containing diets excreted significantly (P<0.05) low levels ammonical nitrogen and orthophosphate, in comparison with the fingerlings fed on fishmeal based diets. Therefore, it is evident that supplementary diets with 40.25% crude protein is required for the optimum growth for the magur, Clarias batrachus fingerlings and live feed is best for the fry of C.batrachus.
