초록

실험동물은 약 135일령(체중 75~80kg) 비육돈 126두(황금돼지, Y × B × D 3원 교잡종)를 선발하여 3 처리구(대조구, 10% 발아보리 + 2% 청보리, 10% 발아보리 + 4% 청보리)에 처리당 42두 씩 완전임의 배치하였다. 시험사료는 시판 비육후기사료에 발아보리(VAW, Vitalised Activated White)와 청보리를 출하시(180일령)까지 45일 동안 첨가 급여하였다. 측정항목은 사료급여량, 증체량, 및 소화율을 측정하였으며, 등급판정은 “축산물품질평가원”에서 실시하였다. 도축 후 식미관능검사(panel test)을 실시하였다. 일당증체량(ADG) 은 대조구의 604g에 비하여 처리1에서 533g였으며, 처리2에서 470g으로 유의적(P<0.05) 감소하였다. 식미관능검사결과 기호성은 각각 대조구(36%), 처리1(28%), 처리2(36%)로 나타났다. 도체등급은 대조구에 비하여 처리1에서 등지방이 낮게 측정되었으며, 육질등급은 대조구(1.125)에 비하여 처리1(0.875), 처리2(0.667)로서 처리에 의하여 1등급 이상로 향상되는 결과를 보였다. 결과적으로 증체량은 감소하였으나 등지방 두께가 감소하고 도체등급이 향상되었으며, 육색이 개선되고, 포화지방산은 감소하고 불포화지방산은 증가하여 돈육 품질이 향상된 결과를 나타냈다.

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.
