Degradation of Peanut Straws in Rumen of Fuqing Goats

  Objective  Digestion of peanut straws (PSs) collected at different seasons and areas in rumen of Fuqing goats was studied.

  Method  Three Fuqing goats permanently in-planted with ruminal cannula were fed PS collected at different seasons and areas. PS1 was harvest at Qingliu on October 28, 2016, PS2 at Qingliu on June 19, 2017, PS3 at Fuqing on June 3, 2017, and PS4 at Qingliu on November 10, 2017. The in-rumen degradation rates of PS with respect of dried matters (DM), acidic detergent fibers (ADF), and neutral detergent fibers (NDF) in 4, 8, 16, 24, 36, 48 and 72 h were determined by placing the PS samples in Nylon bags.

  Result  PS2 and 4 had higher crude protein but lower NDF than the other specimens. The DM, ADF, and NDF degradation rates of all PSs were similar and increased with time in rumen. In 48–72 h, 50%–57% of DM in PS was degraded.

  Conclusion  PS 1 and 4 were shown to have higher degradation rate in the goat rumen indicating a preference in choosing PS harvested in autumn over the other time in a year.
