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.

    EFFECT OF FIBROLYTIC ENZYMES SUPPLEMENTATION IN TOTAL MIXED RATION ON NUTRIENT UTILIZATION AND GROWTH
    (ANIMAL NUTRITION RESEARCH DEPARTMENT COLLEGE OF VETERINARY SCIENCE AND ANIMAL HUSBANDRY ANAND AGRICULTURAL UNIVERSITY ANAND, 2016) HARSHALA A. THUBE; Dr. R.S. GUPTA
    The present study was conducted in two phases to optimize the level of inclusion of fibrolytic enzymes in Surti kids. In Phase-I, in vitro studies were conducted to arrive at the optimum level of incorporation of fibrolytic enzymes in wheat straw based total mixed ration (TMR). On the basis of the results of in vitro fermentation of TMR incorporated fibrolytic enzymes at different levels used as substrate, the optimum level of each was selected, for the in vivo study (Phase II).

    EFFECT OF FIBROLYTIC ENZYMES SUPPLEMENTATION IN TOTAL MIXED RATION ON NUTRIENT UTILIZATION AND GROWTH PERFORMANCE IN KIDS
    (AAU, Anand, 2016) HARSHALA A. THUBE; Dr. R.S. GUPTA
    The present study was conducted in two phases to optimize the level of inclusion of fibrolytic enzymes in Surti kids. In Phase-I, in vitro studies were conducted to arrive at the optimum level of incorporation of fibrolytic enzymes in wheat straw based total mixed ration (TMR). On the basis of the results of in vitro fermentation of TMR incorporated fibrolytic enzymes at different levels used as substrate, the optimum level of each was selected, for the in vivo study (Phase II). Eighteen Surti kids of similar body weight were randomly allotted in to two groups of nine each and were individually fed for 15 days under preliminary period and 120 days experimental period to meet their energy and protein requirements as per ICAR (1998) standards. The kids were fed TMR with no fibrolytic enzymes (T1); and TMR with 0.05% fibrolytic enzymes (T2) The average daily DMI of kids in T1 and T2 groups during digestion trial was 659.33 ± 8.11 and 649.13 ± 6.61 g and when expressed as kg/100 kg body weight was 4.44 ± 0.11 and 4.20 ± 0.0.05 and the same in terms of g/kg W0.75 was recorded as 87.11 ± 1.48 and 83.29 ± 0.70. The DM intake of experimental kids did not differ significantly (P>0.05) when expressed in terms of absolute intake or intake per 100 kg body weight. However, when expressed in terms of DMI/ kg metabolic body weight a significant difference was noted. ii The average digestibility coefficients (%) of nutrients in T1 and T2 groups were 60.83 ± 1.24 and 60.89 ± 0.99 for DM, 63.99±1.17 and 64.49±0.94 for OM, 64.17 ± 1.14 and 64.26 ± 0.88 for CP, 45.50 ± 2.08 and 49.90 ± 2.02 for CF, 71.77 ± 1.00 and 72.18 ± 0.66 for NFE, 54.77 ± 1.69 and 59.76±0.84 for NDF, 47.99 ± 2.16 and 52.39 ± 2.03 for ADF and 69.45 ± 1.74 and 73.12 ± 1.26 for HC of experimental kids under T1 and T2 groups respectively. The cumulative DMI of experimental Surti kids was 77.40±1.07 and 77.10±0.68 kg/head for 120 days in T1 and T2 groups, respectively. The treatment groups did not differ from each other. The average conversion efficiency for DM (kg/kg gain) was 8.63 ± 0.22 and 7.73 ± 0.27, for CP (kg/kg gain) was 0.94 ± 0.10 and 0.91 ± 0.09, for DCP 0.67 ± 0.03, and 0.62 ± 0.03 and for TDN (kg/kg gain) was 5.07 ± 0.20 and 4.59 ± 0.20 in T1 and T2 groups, respectively. The groups differed significantly (P<0.01) from each other. The average daily gain was 78.24 ± 2.25 and 86.36 ± 2.98 g in T1 and T2 groups, respectively. The treatment groups differed significantly (P<0.01) from each other. The increase in the body measurements viz. increase in body length and height at wither of Surti kids under T2 group was numerically higher in comparison to Surti kids under T1. However, the heart girth was significantly higher (p<0.05) in T2 group as compared to T1 (control). The respective values of T1 and T2 groups for rumen parameters: pH (6.34 and 6.20); total N (79.85 and 90.06 mg/dL); NH3-N (19.42 and 23.86 mg/dL), non protein nitrogen (12.72 and 15.42 mg/dL), TCA precipitable-N (38.18 and 44.01 mg/dL) and total volatile fatty acids (7.41 and 9.07 mM/dL), under the treatment groups differed significantly (P<0.05) from each other except for rumen pH. The blood samples collected during experimental feeding, the average total protein, average albumin, average globulin, glucose, cholesterol, triglycerides, BUN, urea and creatinine concentrations were 6.24 ± 0.33 and 6.02 ± 0.17 g/dL, 3.26 ± 0.08 iii and 3.29 ± 0.07 g/dL, 2.99 ± 0.28 and 2.73 ± 0.16 g/dL, 50.65 ± 1.35 and 50.95 ± 1.09 mg/dL, 53.55 ± 2.81 and 53.60 ± 2.07, 37.95 ± 2.02 and 39.30 ± 1.10 mg/dL, 14.37 ± 0.54 and 12.51 ± 0.39, 30.80 ± 1.16 and 26.80 ± 0.83 and 0.80 ± 0.02 and 0.74 ± 0.03 in T1 and T2 group, respectively, which did not differ from each other. The average values (U/L; mean ± SE) of alanine aminotransferase (ALT)/serum glutamic pyruvate transaminase (SGPT), aspartate aminotransferase (AST)/serum glutamate oxaloacetate transaminase (SGOT) and alkaline phosphatase (ALP) of experimental Surti kids in T1 and T2 groups were 31.25 ± 1.18 and 29.25 ± 0.57, 78.10 ± 1.98 and 80.00 ± 2.30, 69.78 ± 8.30 and 48.72 ± 3.25, respectively. The values were comparable between the two dietary treatment groups. These liver enzyme profiles are considered generally as indicators of alterations in body tissue and organs especially that of the pathological changes. The feed cost in terms of Rs/kg gain in T1 and T2 groups was Rs. 134.29 ± 3.33 and 127.25 ± 4.43, respectively. The feed cost per unit gain was statistically lower in group supplemented with fibrolytic enzymes than the control kids (P<0.05). The results indicated that inclusion of fibrolytic enzymes @ 0.05% in TMR (60:40 concentrate: roughage) for growing Surti kids resulted in 10.38% better growth, improved rumen fermentation, increased digestibility of CF and fibre fractions significantly and feed conversion efficiency with 5.53% reduction in feed cost per kg gain in weight as compared to control group.
