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 ON REPRODUCTIVE PERFORMANCE OF POST-PARTUM SURTI BUFFALO ALONG WITH BLOOD PROFILE (HORMONAL AND BIOCHEMICAL) IN RELATION TO SUCKLING AND NON SUCKLING PRACTICES
    (AAU, Anand, 1989) Tiwari, Shailendra R.; Pathak, M. M.
    After calving, 12 primiparous Surti buffaloes were equally divided into two groups; SJCkled and non suckled to study the effect of suckling on post-partum reproductive performance along with blood profile, Post-partum performance included placental expulsion time, weight of placenta, regression of pregnancy corpus luteum, initiation of follicular activity, uterine involution, first heat post-partum postpartum breeding, number of services per conception and senrice period. For blood profile, blood saraplinir was done by tapping . the jugular vein every alternate day from calving to first heat post-partum in addition to first three collections; immediately after calving, immediately after first milking/ suckling and immediately after placental expulsion. Totally 293 samples were analused for blood serum characteristics. The characteristics studied for blood serum were progesterone, estradiol-l7 B, testosterone, triiodothyronine and thyroxine as hortnoncs and total protein, cholesterol (total, free and ester) , alkaline phosphatase, calciuns, phosphorus and copper as biochemical parameters.

    STUDY ON ANTERIOR PITUITARY OF SURTI BUFFALO DURING THE THREE PHASES OF THE ESTROUS CYCLE AND THE TWO SEASONS OF THE YEAR-WINTER AND SUMMER
    (AAU, Anand, 1991) PAI, JAYASHREE P.; PATHAK, M. M.
    With the objective to study anterior pituitary (adenohypophysis) during different phases of the cycle and the influence of season, the study was planned with eighty tour pituitary glands collection from eighty four animals (nearly of same age,healthy and normal Surti buffaloes ) during three phases (Follicular: P1, Luteal: P2, Smooth:P3) of two prominent seasons (summer and winter), The investigation was to know the functional status of anterior pituitary gland specifically for reproductive aspects during the three phases of the two seasons. Collections of the glands were made accordingly (details in materials and Methods) The results of the study to justify the functional status of anterior pituitary gland were co-related with the help of morphological and biometrical, histological and cytologicdi and biochemical and hormonal aspects of the anterior pituitary. The results of morphological and biometrical observations revealed that anterior pituitary gland was larger (by weight and dimensions) and more brownish in colour(due to higher olood supply) during active phases (follicular phase : P1 and luteal phase : P-2) of the cycle. Seasonwise comparison has given clearcut demarcation of winter as peak breeding season.

    STUDIES ON EPISODIC RELEASE OF LUTEINIZING HORMONE AND TESTOSTERONE AND DIURNAL VARIATION IN BIOCHEMICAL PROFILES OF SURTI AND MARWARl BUCKS
    (AAU, Anand, 1990) Patel, Dipakbhai M.; MEHTA, V. M.
    The studies on the episodic release of LH and testosterone as well as the diurnal variation in "biochemical profiles were undertaken in total fourteen Surti and Marwari bucks classified according to the age. The standard Radio Immune Assay and biochemical analytical procedures were -employed respectively for the estimation of levels of hormones and biochemical estimates. The blood samples were drawn for 24 hours period at an interval of 20 min, each. The studies were undertaken during the months of July and August 1989. The basal, mean and peak levels recorded for LH for Surti and Marwari bucks were in the range of 1,0 to 2,4; 5.79 to 7.67 and 13.31 to 17.31 ng/ml during 24 hours period. This trend of LH levels exhibited definite episodic and pulsatile release during light and dark hoiars of the day. The number of LH peaks recorded during dark hours in both the breeds and age groups were significantly lesser as compared to light hours. The mean duration of LH peaks in Surti and Marwari bucks above one year of age during light and dark hours was 20.0 ± 2.82 and 29.5 ± 3.57 min. respectively, Whereas, this duration in Surti and Marwari bucks below one year of age was 17.3 ± 1.15 and 31.8 ± 3.81 during light and dark hours respectively. Though there was no significant difference in duration of LH peak due to age and breed of the bucks however, a significant difference in these characteristics was observed due to light and dark hours. The mean time interval between two LH peaks appeared to be in the range of 130.0 ± 30.08 to 211.0 ± 5.0 min. in both Surti and Marwari bucks of all age groups. A significant difference due to age and light hours was observed in duration of LH peaks in Marwari bucks. However, this tendency was .not observed for Surti bucks. The studies on the time interval between LH peaks followed by testosterone peak exhibited no significant difference in mean time interval between LH and T peaks during 24 hours either due to the age or breeds in present studies. However, younger age group of animals had exhibited shorter time interval between LH and T peaks. The photoperiod was found to have significant effect on time interval between LH and testosterone peaks. During light hours this time interval was shorter when compared with dark hours. The basal, mean and the peak levels of testosterone recorded in both the age groups of Surti and Marwari bucks range between 2.64 to 4.0; 3.61 to 5.36 and 8.33 to 13.60 ng/ml respectively. The present studies on different age groups of Surti and Marwari bucks have revealed the appearance of seven to eight testosterone peaks in 24 hours period. As such there was no significant breed difference in number of testosterone peaks appearing during 24 hours, however, the light and dark hours had exhibited significant difference in the number of testosterone peaks. Total mean time for duration of testosterone peak for both the breeds and age groups of bucks was recorded to be in the range of 23.5 to 28,6 min in present studies. It was further noticed that overall duration of T peaks during light hours was greater than dark hours. The mean time interval between two T peaks range between 148,75 to 177.14 min for both breeds and age.groups of bucks. The time interval between two T peaks was observed to be shorter during light hours as compared to dark hours. The present studies have exhibited the temporal relationship between LH and T secretions in Surti and Marwari bucks of both the age.groups. Similar relationships have been observed in other species of male animals. The studies on diurnal variation in plasma cholesterol level did not reveal significant difference either due to day or night rhythm, age groups or breeds of bucks in present studies, however, the levels reported during light hours were apparantly higher as compared to dark hours. A definite diurnal variation due to light and dark hours was established in levels of plasma alkaline phosphatase in all the animals studied. The AKP activity remained significantly higher during light hours as compared to dark hours. Similar trend was followed during the diurnal variation studies on plasma protein. The present studies have shown evidence that the secretion of LH and testosterone in the bucks is occuring in pulsatile and episodic manner. The patterns of secretion of both the hormones are related to light and dark hours of the day as well as to the age groups- of the animal studied. The biochemical profiles of cholesterol (total, free and ester), AKP and total protein in blood exhibited light and dark hours related fluctuations during 24 hours.
