Definitions
- the present invention relates to an animal coccidiosis control agent, a feed additive, a feed, and an animal breeding method using the same, containing heated cashew nut shell liquid and / or cardanol.
- Animal coccidiosis is a protozoan parasitic infection that is transmitted by oral ingestion of oocysts (capsules of larvae). In some cases, symptoms such as intestinal lesions, diarrhea, loss of appetite, abolition, and weight loss can lead to death. In addition, coccidiosis collapses the microbial flora in the intestines, and diarrhea becomes particularly severe due to mixed infection with pathogenic bacteria. This leads to exhaustion of physical strength and susceptibility to gangrenous enteritis (bacterial infection of the lining of the intestinal tract resulting in necrosis of the intestinal lining of various regions of the gastrointestinal tract) due to reduced immunity. The ruminant coccidiosis is caused by Eimeria bovis , E.

Eimeria zuerniiに自然感染した牛下痢便よりオーシストを集め、生理食塩水5mlにオーシストを1,500個/mlとなるように浮遊させた。対照区には生理食塩水のみを、比較例には非加熱CNSLを各々0.5質量%、0.05質量%、および0.005質量%になるようバイアル瓶に調整した(比較例1、2、および3)。実施例には加熱CNSLを各々0.5質量%、0.05質量%、および0.005質量%になるようバイアル瓶に調整した(実施例1、2、および3)。バイアル瓶は37℃で静置し、適時観察を行った。7日後に実体顕微鏡下で観察し、オーシストの個数の測定、細胞壁の変形や溶解の状態を観察した。
結果を表1に示す。
このように、牛コクシジウムのオーシストを1,500個/ml含む生理食塩水溶液に対して、加熱カシューナッツ殻油を0.05質量%以上となるよう添加すると、本発明のコクシジウム症防除剤の効果が得られる。
Eimeria tenellaに自然感染した鶏下痢便よりオーシストを集め、生理食塩水5mlにオーシストを4,000個/mlとなるように浮遊させた。対照区には生理食塩水のみを、比較例には非加熱CNSLを各々0.5質量%、0.05質量%、および0.005質量%になるようバイアル瓶に調整した(比較例4、5、および6)。実施例には加熱CNSLを各々0.5質量%、0.05質量%、および0.005質量%になるようバイアル瓶に調整した(実施例4、5、および6)。バイアル瓶は37℃で静置し、適時観察を行った。7日後に実体顕微鏡下で観察し、オーシストの個数の測定、細胞壁の変形や溶解の状態を観察した。
結果を表2に示す。
このように、鶏コクシジウムのオーシストを4,000個/ml含む生理食塩水溶液に対して、加熱カシューナッツ殻油を0.05質量%以上となるよう添加すると、本発明のコクシジウム症防除剤の効果が得られる。
