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.

    BIOLOGICAL AND ENDOCRINOLOGICAL STUDIES DURING EMBRYO TRANSFER IN GOATS
    (AAU, Anand, 1997) Baru, Parmod; Dugwekar, Y G
    The present study on biological and endocrinological studies during the embryo transfer in goats was conducted to explore the possibility of using single subcutaneous injection of gonadotrophin for superovulating goats. The study was conducted on the Surti and Marwari goats maintained at Reproductive biology research unit, Anand. The donor goats were grouped in to 5 groups and animals of each group were superovulated using single subcutaneous administration of either PMSG or FSH. The cyclic goats of group - 1 were superovulated using Folltropin - V 200 mg. on day 15 of cycle. The cyclic goats of group 2, 3, and 4 were treated on the same lines with FSH-P 16.5 mg. Folligon 1000 lU and 500 lU respectively. Group 5 acyclic goats were treated with Crestar system for 14 days. The number of goats responding to superovulatory treatment was 3 of 3; 2 of 3; 4 of 5; 5 of 6 and 3 of 3 in groups 1, 2, 3, 4 and 5 respectively. However there was no significant difference between the treatment groups for time taken to exhibit sov-oestrus (24 to 51.5±3.5 h) and duration of sov-oestrus (20.66 ± 1.76 to 27 ± 3 h). The animals of all groups were laparotomized 72 h after breeding to collect the embryos. The total ovarian response, number of GL and UOF recorded in goats of various treatment groups did not differ significantly. The embryos recovered from superovulated goats were at various stages of development from 2 cell to early morula and majority of embryos were of transferable quality. The number of embryos recovered from the acyclic goats were comparatively lower than the number recovered from cyclic goats. The serum P4 concentration in the superovulated goats of various treatment groups showed non significant differences between the various treatments at various intervals of superovulation treatment. The serum P4 on day of embryo recovery was considerably higher in all superovulated goats and exhibited a significant positive correlation with number of CL. (r=0.85) The serum E, concentration was highest on day of sov-oestrus in all superovulated goats and difference between the various treatment group was significant. However the E, concentration had no significant correlation with total ovarian response. The serum biochemical constituents (cholesterol, glucose, calcium and phosphorus) did not show significant variation amongst animals following superovulation between various treatment groups. The embryos collected from the donors of various treatment groups were transferred in to estrus synchronized recipients. The synchrony of oestrus between donor and recipient ranged between ± 24 h. Embryos of 2 cell to early morula were transferred in to recipients. Up to day 35 post embryo transfer six does (16%) returned to estrus. Amongst others four kidded at the end of gestation period yielding ten viable kids. The overall kidding percentage was 31 %. During the study one each birth of single, twin, triplet and quadruplet were recorded. Considerably high incidence of 23 % pseudo pregnancy were recorded in the present study. The serum P4 of pregnant, pseudopregnant and nonpregnant goats on day 35 of embryo transfer had a significant difference (5.9 ± 0.73. 7.93 ± 0.13 and 1.76 ± 0.91 ng/ml, respectively). The serum E" concentration in all the recipients remained low following transfer of embryos up to day 35 of transfer. The rise in E" was much pronounced in the pregnant and pseudo pregnant recipients. The levels of serum biochemical constituents (Cholesterol, Glucose, Calcium and Phosphorous) had no significant difference between the pregnant pseudo pregnant and non pregnant does.
