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 litter type and stocking density on the performance of broilers and composition of used litter
    (CCSHAU, 2007) Sreehari. S; Sharma, R.K.
    Broiler farming can be made more profitable by the use of cheaper litter materials which can be recycled after use without affecting the performance adversely. Stocking density also influences welfare of broilers and thereby contributes to the growth and overall profitability of the operation. Few studies have been conducted in Indian conditions. The present study may provide an answer to whether or not chaffed paddy straw or wheat straw can be used as litter materials, and the stocking density of the birds so that the resulting litter material might be profitably recycled as ruminants feed. Two hundred and forty (240) day-old unsexed, commercial broiler chicks were procured from the private hatchery in February, 2007 and reared on deep litter following standard managemental practices. The experiment was conducted in two phases. In the first phase the chicks were reared on two different litter materials viz., paddy straw and wheat straw at different stocking densities of 0.15 sq.m./bird and 0.18 sq.m./bird. Each treatment had four replications with 15 chicks in each replicate. In the second phase of the experiment the litter from the various treatments were made into stacks, covered with polythene sheet and ensiled for three weeks after addition of molasses and with or without inoculation with fermented milk. The parameters studied were body weight gain, feed intake, feed conversion ratio, moisture content of litter, pH of litter, proximate composition of litter, carcass characteristics, economics of the various treatments, proximate composition of the litter before and after ensiling and pH of the silage. The use of wheat straw as litter material together with a floor space allowance of 0.18 sq.m./bird was found to be most profitable for rearing broilers. The use of fermented milk as a source of lactobacilli during ensiling of broiler litter was found effective in reducing dry matter losses and loss of protein during ensiling of litter.

    Role of prostaglandin PGF2α on the survivability and acrosomal integrity of frozen-thawed semen of murrah buffalo-bulls
    (CCSHAU, 2010) Nain, Surender; Pardeep Singh
    Semen of six Murrah buffalo bulls was used in this investigation. Approximately 200 mini straws of frozen semen from each bull were taken. On the day of experiment 25-30 straws of a bull’s frozen semen were taken from the cryocan and thawed at 37° C for 30 seconds. After thawing semen was transferred to a 10 ml test tube kept at 37° C. Five small test tubes labeled as control, 10, 20, 30 and 40 were kept at 37º C in an incubator. In each test tube 900 μl of thawed semen was transferred. In control tube 100 μl of freshly prepared Tris buffer and in other four tubes 100 μl of PGF2α having concentrations of 10, 20, 30 and 40 μg/ml respectively was added. All five tubes were kept in incubator whose temperature was maintained at 37º C for three hours. After one hour semen from each tube was evaluated for progressive sperm motility, live and dead spermatozoa, abnormal sperms and spermatozoa with intact acrosomes. On completion of two hours of incubation only progressive sperm motility of semen was evaluated. After three hours semen was again evaluated for progressive sperm motility, live and dead spermatozoa, abnormal sperms and spermatozoa with intact acrosomes. The study revealed that addition of PGF2α.at a concentration of 20μg/ml of frozen thawed semen of buffalo-bulls significantly maintained higher sperm motility at each hours of incubation. Livability of the spermatozoa was also significantly higher at 1st and 3rd hours of incubation with the addition of PGF2α @ 20μg/ml as compared to control and other concentrations. Spermatozoa with percent intact acrosomes were significantly higher with the addition of 20μg/ml PGF2α as compared to control and other concentrations at 1st and 3r d hours of incubation. Percent abnormal spermatozoa were significantly less with the addition of different concentration of PGF2α. So it can be concluded from this study that addition of PGF2α at a concentration of 20μg/ml maintains higher sperm motility, livability and more spermatozoa with intact acrosomes up to three hours of incubation of frozen-thawed semen of Murrah buffalo-bulls.
