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.

    STUDY OF HORMONES AND BIOCHEMICAL CONSTITUENTS OF FOLLICULAR FLUID OF UNOVULATED FOLLICLES AND OVARIAN TISSUE IN SUPEROVULATED GOATS
    (AAU, Anand, 2001) DESHPANDE, SATISH B.; Pathak, M. M.
    Totally 24 indigenous goats of Gujarat state were superovulated with Folltropin-V (FSH) and FolHgon (PMSG) during low and peak breeding season of the year to study the hormonal and biochemical profile of follicular fluid of unovulated follicle, luteal tissue and ovarian interstitial tissue of superovulated goats. The goats were mated on the day of superovulatory estrus with an injection of 750 lU of chorulon (LH) to facilitate maximum ovulation and were laparotomized on day-3 of the superovulatory estrus. The superovulatory response was recorded in terms of number of ovulation and number of unovulated follicles. The ovaries were removed surgically and after recording the biometrical changes, 10 % tissue homogenates of luteal and interstitial tissue were prepared in distilled water. The follicular fluid, luteal tissue homogenate and ovarian interstitial tissue honragenate were analyzed for Hormones (progesterone, estradiol-17 p and testosterone), biochemical (total protein and total, free and ester cholesterol), enzymes (AKP, ACP and LDH) and micro minerals (copper, iron and zinc) by standard procedures. The results revealed that the mean ovarian length (21.76 ± 1.89 Vs 13.20 ± 1.06 mm), width (16.04 ± 1.77 Vs 9.74 ± 0.69 mm) and thickness (12.01 ± 1.14 Vs 7.66 ± 0.62 mm) were significantly (P<0.05) higher in superovulated goats than the control one. The differences in these parameters between the two superovulatory drugs were statistically non-significant. The superovulatory response in terms of mean number of ovulation (12.83 ± 2.58 Vs 8.91 ± 1.90) and mean number of embryo recovery (5.91 ±2.14 Vs 3.66 ± 1.11) was recorded significantly (P<0.05) higher in folltropin-v treated animals as compared to folligon treated animals. However, the mean number of unovulated follicles did not differ significantly between the two treatment groups (3.50 ± 0.90 and 3.75 ± 1.65 respectively for folltropin-v and folligon treated animals). The effect of season on superovulatory response was statistically non-significant. The studies on follicular fluid of unovulated follicles indicated that the progesterone, estradiol 17- (3 and testosterone concentration did not differ significantly between the treated groups. The effect of season was also non-significant specifically for estradiol 17-P and testosterone but progesterone was significantly (P<0.05) high during low breeding season. The total protein content was recorded higher in follicular fluid of superovulated goats compared to control (14.47 ±1.20 Vs 12.87 ± 1.12 mg %). The cholesterol concentration was lower in follicular fluid of unovulated follicles compared to control animals but the differences were statistically non-significant. The season also did not influence the cholesterol content in follicular fluid. The AKP and LDH activity was slightly higher in control animals than treated groups. The ACP activity was significantly (P<0.05) higher in PMSG and FSH treated animals than control (2.84 ± 0.20 Vs 3.10 ± 0.16 Vs 2.31 ± 0.15 KAU%). The effect of season was statistically non-significant for AKP, ACP and LDH activity in follicular fluid of unovulated follicles.

    STUDY OF FACTORS INFLUENCING PRODUCTION OF CAPRINE EMBRYOS AND THEIR CRYOPRESERVATION TO KNOW PRE AND POST FREEZING MORPHOLOGICAL CHANGES
    (AAU, Anand, 1999) Sarvaiya, Nitesh P.; Pathak, M. M.
    Totally 30 indigenous goats of Gujarat were superovulated with FoUtropin-V (FSH) and Folligon (PMSG) to see the elfect of gonadotropin during two season ( breeding and non breeding ) to see the effect of season, on superovulatory response, recovery of embryos and quality of embryos. Further to this in the same study effect of onset time for superovulation, duration of SOV oestrus, intensity of superovulation, flushing time and recovery of flushing media on embryo recovery and quality of embryo was also evaluated ctitically. Excellant and good quality embryos were processed for cryopreservation to see the effect of cryopreservation on morphological changes of embryos. An attempt was also made to establish pregnancy by transfering forzen - thawed embryos. Blood samples from donor and recipients were also analysed for hormonal and biochemical parameter. The results revealed that total response was 80 % ( 24 out of 30 ) irrespective of season and treatment. Average time for onset of SOV oestrus was 33.50 ± 5.82 hours with 17.25 :h 0.98 hours as time for duration.

    STUDIES ON THE CONTROL OF REPRODUCTIVE CYCLE IN GOAT
    (AAU, Anand, 2005) PARMAR, AJAYKUMAR P.; Dugwekar, Y. G.
    The present work was conducted with an objective of evolving suitable method for the control of reproductive cycle in goats of local breed of Gujarat. Treatment of does with Chronogest intra-vaginal sponges during non breeding season for a period of 18 days resulted in the exhibition of estrus in all the six treated goats with the onset of estrus within 32.38 ± 0.93 hours and duration of estrus was 48.00 ±1.15 hours. Out of six goats, two became pregnant, whereas in the control group none of the goats exhibited estrus. In the treatment group all the goats had high progesterone levels during luteal phase that reduced to less than 1.0 ng/ml during estrus followed by rise on day 10 post-breeding, which persisted till day 21 only in two goats that became pregnant. Serum estradiol-1713 levels showed significant rise (26.10 ± 1.30 pg/ml) at estrus only in animals that subsequently became pregnant where as in the rest of the animals estradiol-17β level remain around 12.50 ±8.11 pg/ml or lower throughout the experimental period. The levels of serum cholesterol and AKP did not alter significantly during the experimental period either in control or treated goats. Micro minerals, manganese, zinc and copper revealed non-significant difference between control and treatment groups. Iron levels in the treated animals on day of estrus (7.28 ± 0.96 ppm) were significantly high (P < 0.05) than on day 21 of the control group (3.85 ± 0.74 ppm). Similarly, the cobalt levels were found to be significantly higher (P < 0.05) in treated animals on. day 10 as compared to controls. Twelve goats were treated with Chronogest intra-vaginal sponges for 18 days followed by 500 IU PMSG in the day of sponge withdrawal. Six of these received 2.5 ml GnRH on the day of breeding and other six received 750 IU of hCG on the day of breeding. Six animals served as control. Two out of five GnRH treated animals and three out of six hCG treated animals became pregnant. Treatment of goats with chronogest intra-vaginal sponges during breeding season (June to October) for a period of 18 days resulted in the synchronization of estrus in all the six treated goats. Four out of six treated goats became pregnant. All the six goats in control groups exhibited estrus at different time during experimental period. Laboratory made sponges impregnated with 350 mg progesterone were administered intra-vaginally for 12 days in 8 goats during breeding season and 10 goats during non-breeding season. The sponges were left in situ for 12 days followed by administration of 500 IU PMSG on the day of sponges' withdrawal.All the 8 animals during the breeding season and 8 out of 10 animals during the non-breeding season exhibited estrus within 35.14 ± 3.32 hours during the breeding season and 63.00 ± 4.39 hours during non-breeding season The duration of estrus in these animals was found to be 39.00 ± 3.76 hours during breeding season and 33.00 ± 3.26 hours during non-breeding season.
