Abstract

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.
