Effects of levels of ensiled pineapple waste and pangola hay fed as roughage sources on feed intake, nutrient digestibility and ruminal fermentation of Southern Thai native cattle
Abstract
The objective of this experiment was to determine the effect of ensiled pineapple waste (P/A) as roughage source onrumen fermentation and feed utilization of native cattle. Four rumen-fistulated Southern Thai native cattle with initial weight286.1±48.5 kg were arranged to receive dietary treatments in a 4x4 Latin square design. Each period was lasted for 21 days.Cattle were fed concentrate to roughage at the ratio of 65:35. The roughage used was as follows; 1) 100% ensiled pineapplewaste, 2) 65% P/A and 35% pangola hay (HAY), 3) 35% P/A and 65% HAY and 4) 100% HAY. The results revealed that drymatter intake among dietary treatments was not significantly different (P>0.05) (3.70, 3.81, 3.52 and 3.59 kgDM/d). Apparentdigestibility of DM, OM, CP, NDF and ADF in cattle fed only P/A as roughage source was higher (P0.05). Acetic acid, propionic acidand butyric acid concentrations were not significantly different (P>0.05) among dietary treatments. Blood urea-nitrogen wassimilar among dietary treatments. In conclusion, P/A is promising to use as a roughage source for Southern Thai native cattle.
