초록

본 연구는 국내 유기우유 생산 농가와 일반 우유 생산농가의 급여사료(TMR) 내 영양소 성분을 비교하여 우유성분의 변화를 예측하기 위한 기초자료를 제공하기 위해서 수행되었다. 지역별 일반농가와 유기우유 생산농가에서 급여하고 있는 사료 내 조지방, 조섬유 조회분, NDF 및 ADF 함량은 모두 일반농가의 사료가 유기농가에 비해 높게 나타났다(p<0.05). 그리고 조단백질 및 조지방 함량은 모두 일반농가의 사료가 유기농가에 비해 높게 나타났으나 통계적인 차이는 보이지 않았다. 일반농가 급여사료에서 마그네슘 및 아연은 유기농가 사료보다 현저하게 높게 나타났으나(p<0.05), 철, 칼륨, 인에서 차이가 없었다. 유기사료 내 총불포화 지방산의 함량은 일반사료에 비해 현저하게 높게 나타났다(p<0.05). 유기사료에 oleic acid, linoleic acid, linolenic acid의 함량이 일반사료보다 많이 함유되어 있었으나 myristic acid, palmitic acid, stearic acid의 함량은 일반사료가 높게 나타났다.

In order to provide basic data to predict changes of milk components in milk yield, this study was conducted to compare nutritive values of diets collected from organic dairy farms (ODF) and conventional dairy farms (CDF) of Chungnam and Jeonbuk in Korea. The contents of crude fat, crude fiver, neutral detergent fiber, and acid detergent fiber in diets of ODF were significantly (p<0.05) higher compared to those of CDF. The contents of crude protein and crude ash in ODF were also higher (p<0.05) than those of CDF. The contents of calcium, ferrum, and phosphorus in diets of ODF were similar to those of CDF. The contents of potassium, magnesium, and iodine in diets of ODF were higher (p<0.05) than those of CDF. The contents of total saturated and unsaturated fatty acids in diets of ODF were higher (p<0.05) compared to those of CDF. The contents of oleic acid, linoleic acid, and linolenic acid in diets of ODF were higher (p<0.05) compared to those of CDF. However, the contents of myristic acid, palmitic acid, and stearic acid in diets of ODF were lower (p<0.05) compared to those of CDF.
