Abstract

コンビニエンスストアから排出された消費期限切れ食品(コンビニ残さ)の肥育後期豚用発酵リキッド飼料原料としての利用について検討した.コンビニ残さを分別し,弁当めし,おにぎり,菓子パンを主体とする発酵リキッド飼料を調製した.4頭を対照区(新豚産肉能力検定用飼料)に,10頭を発酵リキッド区(FL区)に割り当てた.さらにFL区を5頭ずつCa無添加区(FLN区)とCa添加区(FL+Ca区)に分けた.FL区の肥育成績は対照区と遜色なく,胸最長筋内脂肪含量は対照区(2.9%)に比べて有意に高い値を示した(<I>P</I><0.01,FLN区 : 4.9%,FL+Ca区 : 5.2%).またFL区の皮下内層脂肪中のリノール酸比率は対照区に比べて有意に低かった(<I>P</I><0.01).FLN区とFL+Ca区の肥育成績および肉質に大きな差はなかったが,FL+Ca区で血清中総コレステロール濃度は有意に低い値を示した(<I>P</I><0.05).以上の結果から,分別により粗脂肪含量を抑え,タンパク質源,ミネラル,ビタミンを適切に配合することで,コンビニ残さは肥育後期豚用発酵リキッド飼料原料として利用できることが示された.

The use of expired foods from convenience stores as ingredients of feed for finishing pigs was studied. After sorting out the expired foods, a fermented liquid (FL) feed was prepared by using the sorted rice in lunchboxes, rice balls and sweet buns as main ingredients. Four pigs were assigned as control group in which the animals were given formula feed, and ten pigs were assigned as FL group in which the animals were given FL feed. The FL group was divided into no Ca added group (FLN group) and Ca added group (FL+Ca group) with five pigs each. While the growth performance of FL group was not markedly different to that of the control group, the intramuscular fat in the Longissimus dorsi muscles of FL group (FLN group : 4.9%, FL+Ca group : 5.2%) was significantly higher (<I>P</I><0.01) than that of the control group (2.9%). The linoleic acid percentage of the inner layer of subcutaneous fat in the FL group was significantly lower (<I>P</I><0.01) than that in the control group. The growth performance and meat quality of the FLN and FL+Ca groups were not different, but the serum total cholesterol level in the FL+Ca group was significantly lower (<I>P</I><0.05) than that in the FLN group. These results suggest that expired foods from convenience stores can be used as ingredients of feed for finishing pigs by sorting them to reduce the crude fat content and formulating them with protein source, vitamin and mineral appropriately.
