Abstract
This study was carried out to observe the nutritive effects of feeding rice diet and rice diet mixed with barley or millet, or both on the growth rate and biological availability of some nutrients by albino rats. The experimental diets were prepared on the basis of isocaloric and isonitrogenous containing 357 kcal of energy and 12g of protein per 100g of diet. The experimental animals weighing about 66g of both sexes were fed on 7 kinds of diets such as control diet, rice (100%) diet, rice (70%)+barley (30%) diet, rice (70%)+millet (30%) diet, rice (70%)+barley (20%)+millet (10%) diet, rice (70%)+barley (15%)+millet (15%) diet, and rice (70%)+barley (10%)+millet (20%) diet for 7 weeks. The results obtained are summarized as follows; 1. The gain in body weight was higher for barley and/or millet mixed with rice diet groups than rice diet group with no statistical difference. 2. Although there was no difference in the amount of food consumed by experimental groups, the food efficiency ratio was sightly higher for the miked diet groups than rice atone diet group. 3. The protein efficiency ratio was also higher for barley and millet miked with rice diet groups than rice diet group, although statistical significance was not found. 4. Apparent digestibility of protein of rice diet group was significantly (P<0.01) higher than any other diet group. Although there was no remarkable difference between mixed diet group was found, the apparent digestibility of protein tended to increase when rats were fed on the barley and millet mixed with rice diet. Apparent biological value (p<0.05) and net protein utilization (p<0.01) were also significantly higher for the groups fed mixed diet with barley and/or millet than rice diet group, and those for millet alone mixed diet were slightly lower. 5. The content of total nitrogen in the liver and of protein in serum were not significantly different among experimental groups. It may be concluded from the above results that an adequate supplementation of rice with other cereals and mixing ratio of other cereals to rice were important for the efficient utilization of protein in total diet.
이유(離乳) 직후(直後)의 백서(白鼠)를 대상으로 주곡(主穀)인 백미(白米)와 잡곡(雜穀)인 보리와 속(粟)의 혼식(混食)에 의(依)한 영양효과(營養效果)를 관찰하였다. 시험식이(試驗食餌)는 대조식이(對照食餌), 백미식이(白米食餌), 백미(白米) 70%에 보리 30%, 속(粟) 30%, 보리 20% 일속(一粟) 10%, 보리와 속(粟) 각각(各各) 15%, 보리 10% 일속(一粟) 20% 혼합식이(混合食餌) 등(等) 동열량(同熱量) (357kca1/100g) 및 동단백질수준(同蛋白質水準)(12%)의 7종(種)이었다. 7주간(週間)의 사양(飼養)과 4일간(日間)의 대사시험(代謝試驗)을 통(通)하여 증체량(增體量), 식이효율, 단백질효율(蛋白質效率), 단백질소화율(蛋白質消化率), 생물가(生物價)와 단백질이용률(蛋白質利用率) 및 간장실소(肝臟室素)와 혈청단백질함량(血淸蛋白質含量) 등(等)을 관찰한바 다음과 같은 결론(結論)을 얻었다. 1) 증체량(增體量)은 보리 또는 속혼합식이군(粟混合食餌群)이 백미식이군(白米食餌群) 보다 양호(良好)하였으나 유의적(有意的) 차(差)는 없었다. 2) 식이섭취량(食餌攝取量)은 식이군별(食餌群別)로 약간의 차이(差異)가 있을 뿐 일정한 경향은 없었다. 식이효율은 보리와 속혼합식이군(粟混合食餌群)이 백미식이군(白米食餌群)보다 양호(良好)하였다. 3) 단백질효율(蛋白質效率)도 보리와 속혼합식이군(栗混合食餌群)이 백미식이군(白米食餌群) 보다 양호(良好)하였고 유의차(有意差)는 없었다. 4) 단백질소화율(蛋白質消化率)은 백미식이군(白米食餌群)이 현저히 (P<0.01) 높았고 보리와 속(粟)를 함께 혼합(混合)한 식이군(食餌群)이 높은 경향(傾向)이였다. 생물가(生物價)와 단백질이용율(蛋白質利用率)은 백미식이군(白米食餌群)보다는 보리 또는 속혼합식이군(粟混合食餌群)이 유의(有意)하게 (各各 p<0.05, p<0.01)높았고 속혼합식이군(粟混合食餌群)은 다소 낮았다. 5) 간장실소(肝臟室素)와 혈청단백질함량(血淸蛋白質含量)은 유의차(有意差)없이 유사(類似)하였고 정상치(正常値)의 범위내(範圍內)에 있었다. 본시험(本試驗)의 결과(結果) 백미(白米) 혹은 곡류단백질(穀類蛋白質)을 보강(補强)한다는 것은 많은 단백질(蛋白質)을 첨가(添加)한다는 것 보다는 전체적(全體的)인 균형(均衡)을 이루어 주는 점(點)이 중요(重要)하며 백미식이(白米食餌)가 소화율(消化率)은 우수하나 일단 소화(消化)된 실소(室素)의 체내이용률(體內利用率)이 혼합식이(混合食餌)보다 낮았음은 섭취(攝取)한 단백질(蛋白質)을 절약하며 식품(食品)과 단백질(蛋白質)의 효과적(效果的) 이용(利用)을 위(爲)해서는 곡류(穀類)끼리의 적당한 혼합(混合)과 백미(白米)에 대(對)한 곡류(穀類)의 혼합률(混合率)이 중요(重要)하다고 보며 백미식(白米食)의 보강개량(補强改良)과 절미(節米)의 목적(目的)으로 잡곡혼용(雜穀混用)의 권장 등도 의의(意義)있다고 사료(思料)된다.
