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 DEVELOPMENT OF IMMUNOLOGICAL AND HAEMATOLOGICAL COMPETENCE IN NEONATAL SURTI BUFFALO CALVES
    (AAU, Anand, 1988) PARMAR, KANTILAL S.; Mehta, V. M.
    In the present study, immunological, haematological, biochemical, enzymatic and growth responses of neonatal buffalo calves vaccinated on 10th day were compared with those of control calves. The immunological status of colostrum and milk in relation to stage of lactation and the cross reactivity of colostral immunoglobulins (Igs) between the species were studied. The standard immunological, haematological and biochemical procedures were employed for the evaluation of different estimates from birth to eight weeks of age. The data collected were statistically analysed and are presented. The immunological events both in control and vaccinated groups of neonates revealed that the total Ig concentration in blood serum remained very low in precolostrum sera. Amongst the different fractions of Igs, the IgF-I and IgF-II were present in precolostrum blood serum of both the groups of calves but the IgF-III was absent in both the groups. The colostrum feeding at 15 to 30 minutes after birth increased the blood levels of total Ig and all the three fractions of Igs in both the groups of animals. The blood levels of Ig reached to a peak level at 24 hrs after birth, exhibited a drop from second day to sixth day and increased gradually from seventh day to eight weeks of age. The total Ig in the sera of early vaccinated group of animals increased upto three weeks of age but beyond this a drop in level was noticed upto seven weeks followed an increase at eighth week of age (P<0.01), Studies on three fractions indicated that at 2nd and 3rd week of age, IgF-I and IgF-III were showing a significant (P<0.01) difference between the groups of calves, vdiile the IgF-II did not reveal any difference. The haematological studies in both the groups of buffalo calves exhibited that Pack Cell Volume (PCV), Haemoglobin (Hb) and total Red Blood Cell (RBC) count remained high on the day of birth. The estimates declined significantly on the second day and remained at lower level upto sixth week and again increased between seventh and eight weeks of life. In control group, the Erythrocyte Sedimentation Rate (ESR) was positively and significantly correlated with the age and total globulins in the blood sera, but not in vaccinated groups through out the study period. The total and differential leukocytic studies with control group exhibited a fact that total count and Ig status remained parallel. The neutrophils (N) percentage declined with the advancement of age, whereas lymphocytes (L) increased in this respect. The eosinophils (E) increased upto third day and remained constant afterwards. The per cent monocytes (M) did not reveal any specific trend. The vaccinated group exhibited a rapid decline of N per cent in comparison to control group, whereas, the L per cent rose greater in immunized group. Amongst the blood biochemical estimates, the total serum proteins nearly followed the pattern of total Ig. A significant (P<.0.01) decline in albumin fractions was recorded after colostrum feeding. The alpha globulins did not exhibit any difference, while beta and gamma globulins exhibited significant (P^0.05) difference upto third week of age. The blood enzymes study in control group of calves indicated a steady and significant rise in the Serum Glutamic Oxalo Transaminase (SGOT) and Alkaline Phosphatase (AKP) levels upto 24 hrs and remained almost constant thereafter. The Serum Glutamic Pyruvate Transaminase (SGPT) levels fluctuated much on the first day of life, however. Acid Phosphatase (ACP) levels did not exhibit any significant change throughout the study period. Similarly no specific trend was observed in Lactic Dehydrogenase (LDH) levels. The similar studies in vaccinated group revealed significant (P<0.05) higher SGOT, LDH and AKP activities compared to control group of animals while the SGPT exhibited a reverse trend than this. The growth studies indicated that these calves grew linearly at the rate of 371 grams (gm) per day, with no difference between the groups. The immimological cross reactivity between the colostral Ig of buffalo, cow, goat and sheep was established under the pi^sent Investigation. The study on the effect of lactation on whey protein and Ig status in both the groups of Surti buffaloes remained highest at parturition, dropped subsequently from second day onward till one month period. The adult buffaloes maintained higher whey protein and Ig levels than the heifer buffaloes. The behaviour of three Ig fractions in whey was specific. IgF-I and IgF-II persisted throughout the experiment but the IgF-III disappeared from both adult and heifer buffaloes. The present study revealed the fact that the newborn calf is required to undergo physiological adaptation through periodic immunological, haematological and biochemical behavioural changes, so that the neonatal survival is made possible and effective. The problems of neonatal-calf-mortality can be solved not only through better management but also by protecting them against infectious agents through early vaccinations. The immune system of the neonatal buffalo calf can be stimulated at tenth day of age. Cross reactivity among the ruminant provides a scope of feeding colostrum produced from one species of ruminants to other.

    METABOLIC PROFILE IN POST PARTUM INTER -SE-MATED CROSSBRED (J x K) COWS
    (AAU, Anand, 1996) Patel, Hita N.; Deshpande, Lalita V.
    Twelve post partum inter-se- mated crossbred (J x K) cows were divided into two groups primipara (n=7) and multipara (n=5) to map out the normal trend of circulating metabolic profiles, to effect of parity on these parameters and on occurance of first post partum oestrus, and the correlation of milk production with biochemical perameters. For blood profile, blood sampling was done by tapping the jugular vein every week from calving to day 63. Totally 120 samples were analysed for blood and blood serum characteristics. The biochemical characteristics studied for blood was blood glucose and for blood serum were cholesterol, creatinine, total protein, enzymes alkaline phosphatase (AKP) and acid phosphatase (ACP), calcium, inorganic phosphorus, calcium and inorganic phosphorus ratio and magnesium.
