Sifat Fisik Pakan Kaya Serat dan Pengaruhnya terhadap Konsumsi
Abstract: Fibrous feeds vary
in their physical properties. The experiment aimed to clarify the effect of
physical properties of fibrous component in rations on feed intake and nutrient
digestibility in goats. Rations were composed of 50% fibrous feed and 50%
concentrate. The fibrous feed as treatments were as follows: napier grass (RG),
rice straw (JP), cocoa pod (KC), mixed rice straw and coffee husk (JK), mixed
napier grass, rice straw, coffee husk, and cocoa pod (CP). Rations were offered
to four groups of 20 Etawah-grade goats weighing of 13.50±2.14 kg in a
randomized block design. Physical properties of the fibrous components of
ration and faeces, nutrients intake and digestibility and daily life weight
gain were evaluated. Analysis of variance and correlation were applied to
analyze data. Dry matter intake varied from 298-440 g/day. Goats offered KC
ration had the highest intake. Low feed intake was associated with the low
density of the fibrous component. Dietary fat digestibility decreased when the
fibrous feed component had low capacity of oil adsorption. Young goats had life
weight gain of 50-136 g/day, TDN requirement for maintenance and 50 g daily
gain of 63.4 g and 131 g TDN, respectively. The results indicated that physical
properties of fibrous component in the rations influenced dry matter intake and
nutrients digestibility in growing goats.
