SYNCHRONIZATION OF CARBOHYDRATE AND PROTEIN SUPPLY IN THE SUGARCANE BAGASSE BASED RATION ON IN SITU NUTRIENT DEGRADABILITY
Abstract: Two adult male
sheeps fitted with rumen cannula were used in two experiments to study the
effects of synchronization of carbohydrate and nitrogen supply in sugarcane
bagasse based total mixed ration (TMR) on in situ nutrient degradation. The
first experiment was aimed to create three TMR with different synchronization
index. Ingredient feedstuffs of TMR were evaluated for its in situ organic
matter (OM) and nitrogen (N) degradation kinetics. On the basis of the OM and N
degradation kinetics of feedstuffs, three sugarcane bagasse based TMR were
formulated with synchronization indexes of 0.37; 0.50; and 0.63; respectively.
The TMR had similar levels of crude protein (CP), total digestible nutrients, and
neutral detergent fiber (NDF). In the second experiment, the three TMR with
different synchronization index were evaluated for in situ degradability
characteristics of OM, CP, NDF, and sulfur. The in situ degradation of OM in
TMR were decreased (P<0.05) with the increasing of synchronization index.
The higher synchronization index in TMR increased (P<0.05) CP degradation of
CP. The NDF degradation decreased slightly by the alteration of synchronization
index in TMR. The higher synchronization index in TMR reduced (P<0.05) in
situ sulfur degradation, and this may not support to effects of synchronization
of carbohydrate and nitrogen supply.
