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.

    Genetic studies on performance traits of Hariana cattle under progeny testing
    (CCSHAU, 2006) Sanjeet Kumar; Malik, C.P.
    The present investigation was carried out for genetic studies on performance traits in Hariana cattle under progeny testing. The data on first lactation performance records of 422 Hariana cattle maintained at Germplasm unit, CCS HAU, Hisar; Govt. Livestock Farm, Hisar; Kurukshetra Gaushala, Hisar; Gaushala Bhiwani and Gaushala Jind over a period of 12 years from 1993 to 2004 were analysed for estimation of least squares means, effects of various genetic and non-genetic factors, heritability, genetic and phenotypic correlations. The breeding values of different sires for various performance traits were estimated and product moment and rank correlations among estimated breeding values were calculated. The traits studies were age at first calving (AFC), first service period (FSP), first calving interval (FCI), first lactation milk yield (FLMY), first lactation length (FLL), first lactation peak yield (FPY) and first dry period (FDP). The least squares means for AFC, FSP, FCI, FLMY, FLL, FPY and FDP were 1599.08±16.93 days, 210.60±07.09 days, 492.02±07.09 days, 875.27±25.49 kg, 245.35±04.98 days, 5.03±0.21 kg and 248.47±07.52 days, respectively. The set of sire and period of calving significantly affected AFC and FPY only, while the effect of herd was significant for all the traits. Effect of season of calving and regression of all the traits on AFC was found to be non-significant.
