 note = {Article, 北海道岩見沢市近郊から排出される未利用資源を含む採卵鶏用飼料を設計し、その給与が産卵成績、卵質および卵の化学成分に及ぼす影響について検討した。未利用資源として屑玄米、米ぬか、豆腐粕およびアスパラガスの切り下を用いた。市販の配合飼料を給与する区（対照区）に対し、その25%（25%区）および45%（45%区）を未利用資源で代替する、計3処理を設けた。49週齢の採卵鶏30羽を10羽ずつの3群に分け、1期70日間（予備期10日間、本期60日間）の3×3ラテン方格法にて試験を行った。代替割合が高くなるに伴い、卵のヨークカラーファンは有意に低い値を示し(P<0.01)、卵中粗タンパク質も低い傾向を示した(P<0.1)。また、レチノール含量も対照区に比べ45%区が低い傾向を示した(P<0.1)。しかし、産卵率や上記以外の卵質と卵中成分には処理間に有意な差はみられず、卵黄色や一部の卵成分に差はみられるものの、本研究で設計した45%代替飼料は採卵鶏用飼料として利用可能と示唆された。, Effects of diets including unutilized local resources on production, quality, and chemical composition of eggs of laying hens were examined. The unutilized resources included crushed brown rice, dried rice bran, lees of bean curd, asparagus stems, and seashell powder. The experimental design involved three treatments: a control group (100% commercial feed), a 25% group (75% commercial feed, 25% unutilized resources), and a 45% group (55% commercial feed, 45% unutilized resources). The experiment involved 30 hens (49-weeks old) divided into three groups of 10 each. To reduce systematic error, hen housing involved a 3 x 3 Latin square experimental design for a period of 70 days (a preliminary 10 days followed by a 60-day treatment period). The results show that with increasing replacement rate, yolk pigmentation was significantly reduced (P<0.01) while the content of crude protein tended to decrease (P<0.1). Retinol level in the eggs of the 45% group was significantly lower than that in the control group (P<0.1). However, there were no significant differences among treatments in terms of the egg-laying rate or other parameters of egg quality and composition. Therefore, the 45% alternative feed supply designed in this study can be used to feed egg-laying chickens, although there are differences in egg yolk color and composition.},
