Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    GENETIC ANALYSIS OF PRODUCTION AND REPRODUCTION TRAITS OF HOLSTEIN FRIESIAN CATTLE ON AN ORGANIZED FARM
    (AAU, Anand, 2008) CHANDULAL, PATEL ASHiSH KUMAR; Vataliya, P H
    The body weight, production and reproduction records of Holstein Friesian cattle were collected from H.F. farm, Anand Agricultural University, Anand from 1992 - 2007. Total 278 body weight records at birth weight, body weight at 3, 6 and 12 months under 32 sires and daily milk production records for 209 lactations from 130 cattle were collected. Data up to fifth lactations were collected for each animal. The records were analyzed using least squares analysis procedures incorporating Period, Seasons of calving, parity etc. non-genetic factors in statistical model. The Mixed Model Least-Squares and Maximum Likelihood Computer Programme PC 2 Version of Harvey (1990) was used to estimate genetic parameters from adjusted data by paternal half sib correlation method. Gamma function of Statistical Packages for Social Sciences programme (S.P.S.S. version 10.1) was used for fitting lactation curve. Persistency was calculated on the weekly records of the milk yield. The least squares means for birth weight (BWQ), body weights at 3 (BW3), 6 (BWg) and 12 months (BW,2) were 34.90 ± 0.45, 75.53 ± 0.60, 144.43 ± 1.01 and 248.20 ± 1.24 kg, respectively. Body weights at 3, 6 and 12 months were significantly affected by period of calving and seasons of calving but birth weight was not significantly affected by period and seasons of calving. The calves born in summer season had significantly (P < 0.05) higher body weight at 3, 6 and 12 months than calves born in other season. The parity of dam had no significant effects on body weight at all ages. Sex effects were significant on body weights at all ages and the male calves were heavier than females at all ages. The heritability estimates of BWQ, BW3, BWe and BW12 were 0.028 ± 0.13, 0.201 ± 0.152, 0.096 ±0.15 and 0.113±0.15, respectively.
