EFFECTS OF SUBSTITUTING BARLEY WITH WET SUGAR BEET PULP
SILAGE ON AMOUNT OF TOTAL CRUDE PROTEIN ENTERING İNTO
DUODENUM İN LAMBS: II. NUTRIENT DEGRADATION KINETICS
Summary
The objectives of this study was to evaluate the effects of substituting 30%, 70% and 100%
of energy coming from barley with wet sugar beet pulp silage prepared with mixing
wheat bran on nutrient degradation kinetics in barley based diets. To achieve
this objective, four isocaloric and iso- nitrogenous diets were prepared by
substituting barley energy with wet sugar beet pulp silage (WSBPS) at 0% (control),
30% (30% WSBPS), 70% (70% WSBPS) and 100% (100% WSBPS). The feedstuffs
used in these diets were incubated into rumen of ruminally and duodenually
cannulated Kıvırcık x Morkaraman crossbred lambs for periods of 0, 2, 4, 8, 12, 24 and 48
h. Degradation kinetics of dry matter (DM), organic matter (OM) and crude protein (CP) of
these feedstuffs were determined and degradation kinetics of DM, OM and CP of diets
were then calculated. Degradation kinetics of dry matter (DM), organic matter (OM)
and crude protein (CP) of the feedstuffs used in the experiment were 80.84, 82.20,
and 92.62% for wet sugar beet pulp silage (WSBPS), 62.64, 60.66, and 76.64% for
sainfoin, 68.18, 66.72, and 95.11% for sun flower meal, and 80.46, 89.85, and
96.78% for barley, respectively (P<0.05). Degradation kinetics of dry matter (DM),
organic matter (OM) and crude protein (CP) of the diets used in the experiment were
low at the initiation hours of incubation for all three nutrients proportional to level of
WSBPS, and then caught up the control group by steady increases. In conclusion,
addition of WSBPS slowed down DM and CP degradation rates of the diets and may
positively affect synchronization for microbial protein synthesis.
