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.

    FERTILITY MANAGEMENT IN POSTPARTUM SURTI BUFFALOES THROUGH CLINICAL DIAGNOSIS AND HORMONAL REGIMES
    (AAU, Anand, 2003) KHASATIYA, C. T.; KAVANI, F. S.
    This study was carried out on 59 Surti buffaloes of University farm, Navsari in five groups with the object of monitoring the postpartum period through clinical diagnosis and weekly plasma profile of hormonal, metabolic, biochemical and mineral constituents from day of calving till at least 105 days postpartum without or with GnRH & PGF2α treatment (on day 40-42 and 105 postpartum) with a view to improve their reproductive efficiency. All the animals were periodically palpated per rectum to monitor uterine and ovarian changes and related reproductive peridata. Hormonal profile (plasma P4, T3 and T4) was estimated by standard RIA techniques and biochemical & metabolic constituents (plasma glucose, total protein, total cholesterol, triglycerides, AKP, calcium, phosphorus and magnesium) were determined by using standard kits and autoanalyser. The levels of trace minerals (Zn, Fe, Cu, Co, Mn) were determined on atomic absorption spectrophotometer following wet oxidation of plasma samples. (I) Effect of Hormone Therapy During Early (day 40-42) Postpartum Phase The results revealed that the regression of pregnancy CL and uterine involution were complete by day 9.39±0.27 and 31.22±0.93 without group differences. However, the resumption of ovarian activity (52.75±9.07 day) and first oestrus postpartum (78.80±6.29 days) were earlier in both GnRH and PGFaa treated conceived than control conceived buffaloes. The service period averaged 91.85±7.06 days and calving interval 402.02±7.07 days; both were shorter by 1 cycle in GnRH treated conceived than the control conceived buffaloes (69.93±4.29 vs 87.71±4.00 and 380.36±4.02 vs 400.28±3.97 days), but not in PGF2α treated and control conceived group (59.73±3.76 vs 61.20±10.87 and 369.13±3.80 vs 373.00±10.33 days). The response to both GnRH and PGFaa treatment at day 40-42 postpartum was excellent, as 88.88 % of GnRH treated buffaloes responded and came in oestrus by mean interval of 19.21±1.03 days and 77.77 % of them conceived as against 58.33 % conception rate with a mean oestrus interval of 32.14±9.03 days in control group. In PGF2α treatment group also, 83.33 % treated buffaloes responded with mean interval of 4.07±0.53 days post-treatment and all of them conceived, in contrast to 45.45 % buffaloes conceived with a mean oestrus interval of 13.4±6.76 days in PGF2α control group. The first service conception rate was above 70% in both the treatment groups. As compared to FGFaa (suboestrus) group, the buffaloes of GnRH group with inactive ovaries had significantly higher (P < 0.01) overall mean blood glucose (66.95± 1.46 vs 60.12±1.13 mg%) and total protein (8.70±0.08 vs 8.37±0.09 g%) levels. The weekly mean glucose levels in GnRH treated conceived buffaloes and that of total protein in GnRH control conceived and PGFia treated conceived buffaloes varied significantly between postpartum intervals. The glucose levels were also lower in GnRH treated and control conceived than the non-conceived buffaloes.Further, the mean blood glucose level in GnRH treatment group was significantly higher than its control group (70.16±1.86 vs 62.12±2.35 mg%), but it did not vary between PGF2α treatment and its control group (57.93±1.63 vs 61.45±1.52 mg%). The values were lowest on the day of calving and then gradually increased till 5-8 weeks postpartum, and subsequently fluctuated insignificantly till 15th week postpartum in all the groups. The protein levels were significantly higher at different weeks postpartum, including the overall mean (8.97±0.13 vs 7.92±0.14 g%) only in GnRH treated conceived than non-conceived animals, but not in PGF2α group. The plasma total cholesterol concentration and AKP activity were significantly higher (P < 0.01) in PGF2α (suboestrus) group as compared to GnRH (anoestrus) group (110.20±1.50vs 102.59±1.49mg%and 151.72±5.07vs 116.00±2.12 IU/L). Moreover the levels of cholesterol, in general, were higher and AKP lower in non-conceived than the conceived animals in most groups. The mean plasma total cholesterol levels were lowest on the day of calving, which increased linearly and significantly by 4th to 9th week, and reached to the highest levels by 10th to 14th week postpartum, and then it remained more or less consistent till 15th week postpartum in most groups. The overall mean total cholesterol content of GnRH treated/control and conceived/non-conceived groups was identical, but that in PGF2α treatment group was significantly higher (P < 0.01) than its control at 6th and 7th week postpartum, and also the overall mean (113.42±1.84 vs 104.94±2.55 mg%). Similarly, the AKP activity fluctuated non-significantly between weeks postpartum with overall mean of 122.75±4.37 vs 110.58±5.27 IU/L, respectively, but differed significantly between PGF2α control conceived and non-conceived animals (174.85± 16.45 vs 123.71±4.65 IU/L), and also between PGF2α treated conceived and non-conceived animals at 5th, 9th and 12th to 14th week postpartum including overall mean values.
