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.

    OBSERVATIONS ON COMPOSITIONAL, NUTRITIONAL, IMPLANTATIONAL AND STORAGE ASPECTS OF SPRAY DRIED ACIDOPHILUS-MALT PREPARATION
    (AAU, Anand, 1984) SHAH, RAVIKUMAR KANAIYALAL; Dave, J. M.
    The present study was planned to formulate a spray dried acidophilus-malt preparation in which about 62.3 per cent of milk solids were substituted with wheat solids in the final composition and it contained 10 million live lactobacillus cells per gram. The basic slurry was prepared by blending acidphilus milk and wheat malt in 1:1 proportion and allowed to ferment for three hours. After neutralization it was supplemented with sugar, cocoa and salt at the rate of 7, 3 and 0.1 per cent (w/w) respectively. This was homogenized at 50-70 kg/cm2 and spray-dried at 145-155 C air inlet and 75-80 C outlet temperatures.

    EFFECT OF SELECTED HEAT TREATMENTS AND ADDED AMINO ACIDS ON GERMINATION RESPONSE OF BACTERIAL SPORES IN BUFFALO MILK
    (AAU, Anand, 1982) PATEL, DILIPKUMAR C.; Dave, J. M.
    An experiment was framed to assess the effect of different heat shocks and added amino acids individually as well as in combination with and without incubation for 1 hr at 37°C on spore germination in milk. Ten raw buffalo milk samples collected from Student’s Training Dairy (STD), Gujarat Agricultural University, Anand were analysed for spore count. Ten Amul pasteurized milk samples collected from distribution cans were also analysed for spore count. The results were expressed as spore counts per ml of milk. The average value of mesophillic and thermophilic spore count of raw buffalo milk samples were 172 and 27 per ml respectively. In the same way, the average values mesophilic and thermophilic spore count of Amul pasteurised milk were 298 and 47 per ml respectively.

    SOLID STATE FERMENTATION OF WHEAT STRAW WITH MOLD INOCULATION AND NUTRIENTS SUPPLEMENTATION TO ENRICH THE FEED
    (AAU, Anand, 1989) PRAJAPATI, JASHBHAI BHIKHABHAI; NEELAKANTAN, S.
    Considering the quantitative importance of cereal straws and the need for feeding these residues to the large populations of livestocks especially in developing countries, considerable efforts have been made to upgrade their nutritive value. Recent biotechnological approaches utilising efficient and improved micro-organisms for bioconversion of cereal crop residues with supplementation under optimised fermentation conditions has provided enough basic knowledge and encouragement to produce a wholesome feed with higher digestible organic matter and crude protein availability. An attempt has been made in the present study to initially screen the candidate lignocellulolytic fungi for their better competitive saprophytic ability on wheat straw. Among the 29 molds tested in sterile and unsterile wheat straw with supplements like water, urea, whey and butter milk, the best eleven molds selected included Pleurotus sp. P3 , P2 , P7H7 and Z-15, N. sitophila 3189 and ATCC 36935, C. velutipes, C.cinereus, A. terreus, C. cladosporindes and P. chrysosporium. The cultures were tested for SSF of wheat straw with urea, whey or butter milk supplementation for 7 days under sterile and unsterile conditions and the samples were evaluated for digestible dry matter .and crude protein recoveries. During the SSF of water, or urea supplemented straw, C. velutipes resulted in less DM loss (7.72-12.88%) and consequently yielded higher DDMR (45.02-48.90%) in the fermented straw. Pleurotus sp. P7H7 and P. ostreatus Z-15 showed comparatively higher DDMR (42.55-47.26%) and minimum DM losses (5.58-10.35%) in urea supplemented straw under sterile and unsterile condi- , tions. In whey or butter milk supplemented straw, all the eleven molds showed lower DDMR than the control straw. The CP recovery in the fermented straw was in the range of 3.78 to 10.39% during SSF by various molds.
