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 PERFORMANCE OF FOUR CROSS-BRED COLOURED BROILER PARENTS SUITABLE FOR BACKYARD POULTRY FARMING
    (AAU, Anand, 2009) MHATRE, SUSHANT JAYAVANT; Khanna, Kuldeep
    The different breeds used as female line to produce crossbreds were RIR, AP and AK, whereas, B was used as male line and the reciprocal cross of RIR was also produced. Simultaneously, pure breed RIR, B, AK and AP were also maintained to evaluate comparative performance between crossbreds and pure breeds. The backcross progenies were produced by using B as a male line with an objective to evaluate growth performance of next generation. Thus the present study was divided into two parts i.e. to study the production and reproductive performance of crossbreds and to study the juvenile growth rate of their backcross progenies. The traits studied both for the crossbreds and purebreeds were growth rate, AFE, body weight at sexual maturity, total egg number, HHEP and HDEP (%), egg weight, total feed consumption, fertility and hatchability, hatching performance, livability and economics in terms of feed cost. The traits studied for the backcross progenies were body weight, weight gain, feed consumed, FCR, livability and economics in terms of EPEI. Among the crossbreds RIRB performed better than other genetic group at all ages except 12, 14 and 16 week. At 12, 14 and 16 week highest body weight was observed in BRIR. The lowest body weight was observed in BAK as compared to other crossbreds during growing and laying period. The body weight results showed statistically significant (P<0.05) differences among crossbreds and pure breeds. The average age at first egg was found to early in BRIR and it was found to be delayed in RIRB as compared to other crossbreds. The results indicated that the body weight at sexual maturity was higher for crossbreds as compared to the pure breeds. In crossbreds the total egg number per dam upto 40 and 60 week of age on hen housed basis was found to be higher in BAP and BRIR respectively whereas, it was lowest in RIRB. The percent HHEP for crossbreds during the period of 21-60 week was ranged from 53.97 (RIRB) to 61.12 (BRIR) whereas, percent HDEP during 21-60 week of age was ranged from 54.01 (RIRB) to 63.08 (BAP). The egg production in the crossbreds was observed to be higher as compared to the pure breeds. The egg weight in the crossbreds was found higher in RIRB and lower in BAK whereas, in pure breed it was higher in B and lower in AK during 28, 32, 40 and 60 week of age. The total feed consumption of crossbreds upto 60 week of age ranged from 46.43 kg (BAK) to 46.70 kg (RIRB). The data on depletion of birds showed that among crossbreds BRIR, RIRB, BAP and in pure breeds RIR, B, AK had 100 percent livability during the 12-20 week period. In the crossbreds lowest percent livability during growing period was observed in BAK i.e. 97.30. The crossbreds BRIR (98.15) had shown the highest livability and it was lowest in BAP (92.60) during the laying period. The result indicated that crossbreds had better livability as compared to pure breeds. The results revealed that the fertility and hatchability on TES and FES were higher in the crossbreds than the pure breeds. It was observed that the percentage of hatchable eggs and chicks were highest in BAK and it was lowest in BRIR. Whereas, the hatchable eggs per dam and chicks per dam were highest in BAP and it was lowest in RIRB. The feed consumed (kg) per hatchable eggs and feed consumed per chick was lowest in BAP whereas it was highest in RIRB. The results had shown that the feed cost (Rs) per egg was lower in BRIR and it was higher in RIRB. Whereas, the feed cost per hatchable egg and feed cost per chick was lower in BAP and it was higher in RIRB. The result was found that among backcross progenies BRIRB had highest body weight during whole 6 weeks period and the lowest body weight was observed in BBAK at day old, 2, 6 week whereas in BBRIR at 4 week of age. In general BRIRB had better weight gain as compared to other crossbreds. The lowest total feed consumption upto 42 days was observed in BBRIR and it was highest in BRIRB. Overall, the FCR for 42 days period was found to be best in BBRIR as compared to the other breeds and poor FCR during that period was observed in BBAK. The BRIRB and BBAK had shown highest livability percent and it was lowest in BBRIR and BBAP upto 6 week of age. It was observed that the highest EPEI was observed in BBRIR and lowest EPEI was observed in BBAK.
