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.

ThesisItem Open Access STUDY ON GENETIC ASPECTS OF RESIDUAL FEED CONSUMPTION (RFC)AN IMPORTANT FEED EFFICIENCY TRAIT IN POULTRY FOR EGG(AAU, Anand, 1998) Joshi, Rajeshkumar S.; Solanki, J. V.A study on genetic aspects of Residual Feed Consumption (RFC) was carried out at C.P.R.S., Anand using 414 and 454 pedigreed pullets belonging to 37 and 30 sire families of synthetic flock of WLH birds in S1 and S2 generation respectively. The mean RFC or accumulated RFC was not significantly different from zero during 4 weekly interval in both generations (range for RFC during 4 weekly periods were - 10.0 to 11.562 in S1 while - 9.981 to 9.013 in S2 generation birds). Mean cumulative RFC during 21-40, 21-56 and 21-72 weeks periods were -0.199, -0.191 and - 0.339 gm while -0.208, -0.250 and 0.010 gm in S1 and S2 generations respectively. Also coefficient of determinations (R2 values) were found lower viz. 0.50 to 10.7 % in S1 generation whereas 1.0 to 10.4 % in S2 generation.ThesisItem Open Access GENETIC STUDIES ON PLASMA TRIGLYCERIDE -VERY LOW DENSITY LIPOPROTEIN (TG-VLDL) AND ITS ASSOCIATION WITH GROWTH, EGG PRODUCTION AND FEED EFFICIENCY TRAITS IN A SYNTHETIC STRAIN OF WHITE LEGHORN(AAU, Anand, 1998) Savaliya, Fulabhai P.; Solanki, J. V.The present study was carried out to investigate inheritance and association of plasma Triglyceride - Very Low Density Lipoprotein (TGVLDL) concentration at 18 and 28 weeks with various traits in a synthetic strain of While Leghorn in two successive generations. At each generation 476 pullets (belonging to 37 and 30 sire families in first and second s generation, respectively) were utilized as experimental material. The means, heritability and genetic and phenotypic correlations were computed through Least Square Analysis using LSMLMW and MIXED MODEL computer programme. The plasma TG-VLDL concentration were estimated by using Triglyceride enzymatic kit. The mean plasma TG-VLDL was found to be 189.337 + 11.154 and 409.607 + 29.850 mg% at 18 weeks and 989.257 + 11.852 and 964.630 + 22.707 mg% at 28 weeks in first and second generation, respectively. The least squares means for body weight at 18, 20, 32, 40, 56 and 72 weeks for age at first egg, for egg number produced up to 40, 56 and 72 weeks, egg weight at 28, 32, 40, 56 and 72 weeks, egg mass produced up to 40, 56 and 72 weeks, feed consumption per day, feed consumption per dozen eggs and feed consumption per kilo eggs during 21-40, 21-56 and 21- 72 weeks period were computed in each generation. Hatch effect was found significant for TG-VLDL at both the ages, body weight at all the ages except at 18 weeks, age at first egg, egg number up to 40 and 56, mean egg weight at 32, 56 and 72 weeks, egg mass at 40 weeks and feed consumption per dozen eggs during 21-40 weeks in second generation. The heritability estimates for plasma TG-VLDL were 0.289 ± 0.259 and 0.272 + 0.133 at 18 weeks and 0.541 + 0.202 and 0.703 + 0.208 at 28 weeks in first and second generation, respectively. The heritability estimates were moderate at 18 week and high at 28 weeks of age. The estimates of heritability for body weight were high at all the ages in both the generations except at 56 and 72 weeks in second generation. The heritability estimates for age at first egg were 0.453 + 0.168 and 0.710 + 0.207 in first and second generation, respectively. It was highly heritable character in both the generations.

The egg weight showed high estimates of heritability in both the generations. However, heritability estimates obtained at 32 and 40 weeks in first generation and at 28 and 56 weeks in second generation exceeded the parametric range. Egg mass showed decreasing trend of high to moderate estimates of heritability with advancement of age in first generation and reverse trend of similar magnitude was observed in second generation.

The heritability estimates for feed consumption per day were found high at all the periods in both the generations. The feed consumption per dozen eggs showed high estimate of heritability during 21-40 weeks (0.411 + 0.162) and moderate estimates during 21-56 weeks (0.336 + 0.153) and 21- 72 weeks (0.301 + 0.187) period in first generation while they were moderate during 21-40 weeks (0.169 + 0.112) and 21-72 weeks (0.204 + 0.132) and low during 21-56 weeks (0.062 ± 0.093) in second generation.

The high TG-VLDL18(O) group, birds have significantly (P<0.05) earlier (21-22 days) age at first egg and have produced more egg with slightly lower weight throughtout the period of lay. They have higher egg mass production at all the ages in both the generations except at 72 weeks in first generation. The high TG-VLDL18(O) group birds have better feed efficiency than low group birds. The high TG-VLDL28(O) group birds showed higher body weight at all the ages, have produced more eggs and egg mass but have lower egg weight than low TG-VLDL28(O) group. The high TG-VLDL28(O) group birds have better feed efficiency than the low TG-VLDL28(O) group birds. High TG-VLDL18(S) group birds have lower body weight at all the ages after 20 weeks, as compared to low TG-VLDL18(S) group. The high TG-VLDL18(S) group birds matured significantly earlier (13-14 days) and have produced more number of slightly lower weight eggs throughout the laying period, but have produced lower total egg mass up to 72 weeks of age as compared to low TG-VLDL18(S) group. High TG-VLDL28(S) group birds have higher body weight at all ages as compared to low TG-VLDL28(S) group birds. The high TG-VLDL28(S) group birds were matured significantly later but have produced more number of eggs, higher egg weight and egg mass and have better feed efficiency than low TG-VLDL28(S) group.
