IN-VITRO EVALUATION OF PIGEON PEA (Cajanus cajan) STRAW IN TOTAL MIXED RATION
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 60
Abstract
An in vitro study was conducted to know the optimum level of replacement of concentrate mixture and incorporation of pigeon pea straw in total mixed ration. The TMR control was prepared by mixing concentrate mixture and wheat straw while in other respective TMRs concentrate was replaced by pigeon pea straw at the rate of 5%, 10%, 15%, 20% and 25%. The concentrate and roughage ratio was kept at different level as 45:55, 40:60, 35:65, 30:70, 25:75 and 20:80 under TMR P0 (control), P1, P2, P3, P4 and P5, respectively. The average values of in vitro dry matter digestibility 66.47, 66.58, 66.61, 65.55, 65.78 and 62.11%, respectively. The statistical analysis of data revealed significant (P<0.05) decrease in IVDMD under P5 treatment group. However, the treatment differences for in-vitro dry matter digestibility (IVDMD) in P0, P1, P2, P3 and P4 group were non-significant. The in-vitro organic matter digestibility (IVOMD) at 24 h incubation for P0, P1, P2, P3, P4, and P5 treatment groups were observed as 65.84, 66.03, 65.95, 66.11, 65.39 and 60.64% and the statistical analysis of data revealed significant (P<0.05) decrease in IVOMD in P5 treatment group as compared to other groups while all other groups was having non-significant difference for IVOMD. The values for TGP were 87.75, 81.75, 82.00, 82.75, 82.25 and 83.00 ml/500 mg TMR for P0 (control), P1, P2, P3, P4 and P5, respectively showing that P0 having highest (P<0.05) gas production. Result showed that there was no effect on IVDMD and IVOMD from P0 to P4 TMRs but by 25 % replacement of concentrate by pigeon pea in P5 TMR there was significant decrease in IVDMD and IVOMD. However, there was significant decrease in gas production was observed in TMR incorporated with pigeon pea straw by replacement of concentrate from control TMR comprised of only wheat straw as roughage source.
