    Studies on Various Treatment Conditions Affecting Urea-Ammoniated Rice Straw in Ghana
    (University of Ghana, 1992-06) Quashie, B.S.; Fianu, F.; Assoku, R.K.G.; Amaning-Kwarteng, K.; University of Ghana, College of Basic and Applied Sciences, School of Biological Sciences, Department of Animal Biology and Conservation Science (DABCS)
    Four experiments were undertaken to evaluate the effect of various treatment conditions on the nutritive value of urea-ammoniated rice straw. Experiment 1 was carried out to determine the optimum condtions necessary for ammoniating rice straw with urea. The factors investigated included urea concentration (3 .5 , 4.0, 6.5 and 8.0% W/w), treatment period (7, 14 and 21 days) and moisture le v e l (40, 50 and 60%), in a 4 x 3 x 3 factorial experiment. Samples were analysed for to ta l Nitrogen content, neutral detergent fib r e (NDF), acid detergent fibre (ADF) and in v it r o organic matter digestibility (IVOMD). Results showed that the optimum urea concentration, treatment period and moisture le v e l ware 6.5%, 21 days and 40% respectively. In Experiment 2, the optimum conditions obtained in Experiment 1 were used to treat rice straw which was then stored in different types of silo (earthern pit, cane basket and cement cu lv e r t) to determine the best silo to use. The earthern p it was found to be the best among the silo s with its contents having a N content of 1.75% and IVOMD 52.65. Straw from the basket and culvert had 1.55% and 1.10% N and 50.03 and 43.21 IVOMD respectively. The in situ rate of ruminal dry matter (DM) disappearance (DMD) (3-72h) and extent of DM disappearance (72h) investigated in Experiment 3 indicated that urea ammoniated straw was more fermentable in the rumen of sheep compared with untreated rice straw. The rate and extent of DMD was found to be 0.48%/hr and 44.64% for untreated rice straw and 0.74%/hr and 58.97% for ammoniated rice straw. Urea treatment significantly increased straw intake but did not prevent sheep freight los s in Experiment 4. Straw ensiled with urea for 21d and fed to sheep with little supplementation can supply maintenance needs of ruminants during the dry season.
