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.

    STUDIES ON GROWTH, REPRODUCTION AND PRODUCTION PERFORMANCE OF DIFFERENT GENETIC GROUPS OF GIR CROSSBRED
    (AAU, Anand, 1995) Nagare, Walmik K.; Patel, Ashok M.
    The total 3235 records of Gir halfbreds, triple breds and their interse crosses from 1972-1992 were collected from All India Co-ordinated Research Project on cattle, MPAU, Rahuri (RCDP) M.S. The least squares analysis (Harvey, 1990) was carried out to assess the influence of genetic groups, the year of calving and season of calving on growth, reproductive and productive traits, in addition to the herd structure, mortality, disposal pattern of animals, reproductive wastage and the heterosis. The significant genetic group differences for growth, reproduction and production traits were observed, indicating genetic variability to improve these traits through selection. The least squares means for body weights of FG halfbreds were significantly heavier at all ages to JG counter part. Birth weight was 26.51 ± 0.76, 21.54 ± 0.83, 26.45 + 0.64, 24.86 ± 0.68 and 31.11 ± 0.76 kg in FG, JG, FJG, JFG and BFG groups and for IFG, IFJG, IJFG and IBFG interse, it was 25.84 ± 1.04, 25.54 ± 0.69, 23.41 + 0.77 and 27.96 ± 0.68 kg respectively. FG gained superiority over other grades for body weights at 3, 6, 12 and 18 months, weight at first service and weight at first calving also. Year of birth had highly significant variations for body weight at different ages, whereas season of birth showed nonsignificant effect on growth rates during different ages except at 6 months. Amongst three breed crosses BFG (313.79 ± 6.10 kg) heifers were heavier by 6.19 kg than FJG (307.69 ± 5.60 kg) and by 24.2 kg than JFG (289.59 ± 5.56 kg) at 18 months age. BFG and FJG were at par but differd significantly than JFG while interse, IFJG, IJFG, IBFG and IFG weighed 293.31 ± 5.10, 269.03 ± 6.15, 287.75 ± 5.49 and 287.01 ± 8.24 kg respectively, estimating a loss of heterosis to the tune of 4.65, 7.99, 8.30 and 21.58 percent. The overall growth rate from birth- 3 mo; 3-6, 0-6, 6-12, 0- 12, 0-18 month, 12 months -AFS and from AFS to AFC was 370, 483, 425, 580, 498, 490, 356 and 324 g/day and was the highest during 6-12 months of age. AFC was observed to be 839.36 + 14.11, 801.54 ± 16.52, 821.50 ± 13.06, 827.23 ± 13.41, 855.55 ± 13.54 and 923.27 ± 14.83, 857.78 ± 10.10, 884.23 ± 13.06, 917.63 ± 12.07.days in FG, JG, FJG, JFG, BFG, IFJG, IJFG, IBFG and IFG respectively. The respective least squares means for service period were 123.02 ± 5.13, 101.72 + 7.46, 120.32 + 5.71, 106.46 ± 6.23, 114.66 + 5.93, 140.43 ± 5.69, 125.81 + 7.31, 145.95 ± 6.67 and 130.78 + 7.56 days; the dry period was 80.52 ± 3.33, 70.63 ± 5.19, 76.42 ± 4.03, 66.38 ± 4.63, 78.65 ± 4.41, 87.38 ± 3.65, 79.37 ± 5.45, 86.21 ± 4.71 and 86.95 ± 5.60 days and the calving interval was 414.77 ± 4.31, 392.85 ± 6.71, 409.65 + 5.21, 398.92 + 5.98, 410.33 ± 5.00 and 428.99 + 4.71, 420.02 + 7.04, 435.42 ± 6.08 and 413.57 ± 7.24 days in interse, respectively.
