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 GROWTH AND PRODUCTION PERFORMANCE OF BACKCROSSED COLOURED BROILER PARENTS SUITABLE FOR RURAL FARMING
    (AAU, Anand, 2009) MAHADIK, PARAG PRABHAKAR; Joshi, R. S.
    A study was under taken on backcrossed coloured broiler parents for growth and production performance. The backcross of Caribro as a male line with crosses namely Broiler X RIR (BR), Broiler X Kadaknath (BK), Broiler X Aseel peela (BAP), Broiler X Naked neck (BN), Broiler X Assel kala (BAK), Broiler X Frizzle (BF), Broiler X White Leghorn (IWP strain) (BW) as a female line. Also RIR as male line X Caribro as female (RIRB) were produced by means of artificial insemination. Thus, a total of eight different backcross were evolved for the present study. And the traits studied were growth traits, egg production traits, feed consumption traits, fertility (%) and hatchability (%) traits, mortality and economics. The results revealed that among all the back cross parents BBF and BBN crosses had shown higher body weight while BBW and BBAP crosses have shown lower body weight upto 40* weeks of age at almost all stages. All the genetic group differ significantly (P< 0.05) at all the stages. The results shown that the body weight gain of BBF, BBRIR, BBAP and BBW crosses was higher during the experimental period as compared to other crosses. While BBN has the lower body weight gain during the whole experimental period. The body weight gain revealed that the genetic groups differ significantly (P< 0.05) at all ages. The age at first egg in flock was observed lower in BBRIR (132nd days) cross while BBF (158 days) was the cross start production late. In general, it was observed that the BBRIR cross came in production earlier as compared to the other crosses. The Survivor egg production of the different genetic group ranged between (64.44 ± 2.72 eggs) BBF and (77.40 ± 1.48 eggs) BBN crosses. The genetic group had significant (P<0.05) effect among various backcross parents. The rate of lay for all the crosses from 21st - 40th weeks period shown that the hen house egg production of all the crosses ranged between 45.37 % (BBAP) and 55.29 % (BBN). While the hen day egg production ranged between BBAP (45.64 %) to BBN (55.29 %). Over all, the rate of lay (hen house and hen day) from 21st- 40th weeks differed significantly (P<0.05) for all crosses. The highest rate of lay observed in BBN cross and lowest rate of lay recorded in BBAP cross during 21st -40th weeks period. The egg weight of BBN is higher as compared to the other back crosses, followed by BBF which was lower in 28th and 32th weeks but was higher in 36th and 40th week. It was observed that genetic group had significant (P<0.05) effect on egg weight at various intervals among various backcross parents. The average egg mass produce by all the crosses ranged between BRIRB (3.306 kg) and BBN (4.272 kg). It was observed that BBF has the higher feed consumption of 28.55 kg followed by BBRIR, BBN, BBW, BRIRB, BBAP, BBK and BBAK having feed consumption of 27.362, 27.258, 27.121, 27.031, 26.814, 26.752 and 26.522 (kg) respectively. BBAK has the lower feed consumption among all the back cross parents. It was observed that feed consumption per dozen of eggs produced was highest for BBF (3,26 kg) while feed consumption per killo eggs produced was highest for BRIRB (5.30 kg) cross but feed consumption either per dozen or per killo of eggs produced was lowest for BBN (2.72 kg) respectively and indicate good conversion efficiency compared to other genetic groups. The fertility of the entire crossbreds ranged between BBK (92.93 %) and BBW (85.35 %). The overall fertility of all the cross breds was 89.92 %. The hatchability on total egg set basis for all the backcross parents ranged between BBK (90.63 %) and BBW (82.15 %). While on fertile egg set basis ranged between BBK (97.52 %) and BBF (93.20 %). The overall hatchability on total egg set and fertile egg set basis for all the crossbred were 85.99 % and 95.73 %. It was observed that BBK cross has higher fertility as well as hatchability of all the genetic group. During the experimental period (grower phase 6* -20* weeks) no mortality were recorded in BBAP, BBN, BRIRB and BBAK crosses but BBK (5 %), BBRIR (3.33 %) and BBW shown (1.67 %) mortality. During the laying phase, BBRIR, BBAP, and BBW shown 1.67 % mortality. There were no mortalities observed in BBK, BBN, BRIRB, BBAK, and BBF during laying phase. The total mortalities observed were 1.98 % only. The overall economics, shown that BBRIR cross was most economical as it has got 1.78 Rs profit per chicks produced over feed cost while BBW cross was least economical as it has rewarded with only 0.40 paise per chick produced over feed cost.
