The Effect of Vitalised Activated White(VAW) and Green Barley Straw(GBS) Feeding on Digestibility and Carcass Grade in Golden Pigs

Abstract

One-hundred twenty six "Golden Pigs" (YxBxD three-way crossbreed, 135-day old, 75~80kg BW) were randomly assigned each 42 pigs in three treatment groups. Three treatments were control, treatment 1 (10%VAW + 2% green barley straw), and treatment 2 (10%VAW + 4% GBS). Experimental diets were mixed commercial diet with vitalised activated white (VAW) and green barley straw(GBS) and then fed 45 days. Measurements were feed intake, weight gain, and digestibility. Meat grade were measures from "Korea Institute for Animal Products Quality Evaluation, KAPE". ADG was significantly (p<0.05) decreased in treatment 1 (533g) and treatment 2 (470g) that in control group. Meat panel test were control (36%), treatment 1 (28%), treatment 2 (36%). Back fat was low in treatment 1. Meat grade were control (1.125), treatment 1 (0.875), and treatment 2 (0.667). Therefore meat guality was improved by treatment. In result, VAW and green barley straw addition was improved meat quality without other detrimental effects in finishing pig.
