Abstract:
In vitro dry matter (DM) digestibility of green panic (Panicum maximum) dried to approximately 60% DM, treated with 30 g urea N kg-1 DM (UH) and left to be dried in an open stack was considerably higher than that of common panic hay (PH) (69% vs. 63%). The objective of the present study was to confirm these findings in vivo. Lucerne hay (LH) was added as a reference material. Urea treatment maintained lower neutral detergent fiber and lignin contents of green panic. Daily intake of digestible organic matter of UH (kg-1 W0.75), its digestibility (%), and its metabolizable energy (ME) density (Mcal kg-1 DM), were significantly higher than those of PH (49, 59 and 2.17 vs. 37, 57 and 1.97, respectively) and similar to those of LH. Nitrogen retention was highest in the UH treatment, indicating that some of the non-protein N was converted into microbial protein. Mean retention times (MRT) of digesta particles of PH, UH and LH in the entire digestive tract were 49, 42 and 35 h, respectively. © 1990.
