Embodiment 1: do not attack worm and not offer medicine group (negative control group),
Embodiment 2: attack worm and not offer medicine group (positive controls),
Embodiment 3: attack worm Radix Dichroae dosage group (containing Radix Dichroae extract 40mg-160mg)
Embodiment 4: attack worm height Radix Dichroae dosage group (containing Radix Dichroae extract 160 mg),
Embodiment 5: attack Radix Dichroae dosage group in worm (containing Radix Dichroae extract 100 mg),
Embodiment 6: attack worm low Radix Dichroae dosage group (containing Radix Dichroae extract 40 mg).
7 days experimental periods, on-test and at the end of by only weighing, observe chicken spirit, diet and feces situation therebetween, full group cutd open and killed last day.
Evaluating drug effect with anticoccidial Index A CI for its anticoccidial effect of standard determination: ACI < 120 is invalid; ACI=120 ~ 160 are poor efficiency; ACI=160 ~ 180 are middle effect; ACI > 180 is efficient.
ACI computing formula: ACI=(body weight increase rate+survival rate) × 100-(pathological changes value+egg capsule value)
Body weight increase rate=test group average growth rate/normal healthy controls group average growth rate × 100%
Pathological changes value=often organize average lesion to score × 10
Caecum lesion standards of grading: caecum is normal is 0 point without egg capsule; Have egg capsule, caecum mucosa thickens, and having being dispersed in property on a small quantity hemorrhage is 1 point; Have egg capsule, caecum mucosa thickens, and has obvious blood or blood content to be 2 points; Have egg capsule, caecum mucosa thickens, and has a large amount of blood clot or blood sample intestinal core to be 3 points; Have egg capsule, caecum outward appearance is caramel, obvious tumefaction, and content blood sample is 4 points; Because coccidium infection death also calculates 4 points.
The computational methods of egg capsule value: when the ratio namely infecting the O.P.G value of latter 7 days chickens and the O.P.G value of not administration group chicken is less than 1%, egg capsule value is 0; 1% ~ 25% time, egg capsule value is 5; 25% ~ 50% time, egg capsule value is 10; 50% ~ 75% time, egg capsule value is 20; 75% ~ 100% time, egg capsule value is 40.
Anticoccidial index (ACI) is calculated according to body weight increase rate, survival rate, pathological changes value and egg capsule value etc., result shows: the ACI of high, medium and low Radix Dichroae dosage group is respectively 131.2,183.9 and 169.8, judges that its curative effect is poor efficiency, efficient and middle effect (see table).In, low Radix Dichroae dosage group shows good gaining effect, so ACI is higher, anticoccidial effect reaches efficient and middle effect; And the toxic and side effects that high Radix Dichroae dosage group may be brought because Radix Dichroae extract is excessive, growth is obviously suppressed, and cause ACI to reduce, anticoccidial effect is deteriorated on the contrary.
The anticoccidial effect of the extracts such as table 1 Radix Dichroae and Radix Astragali crude polysaccharides prescription
Embodiment | Average starting weight/g | Average end weight/g | Body weight increase rate/% | Survival rate/% | Pathological changes value | Egg capsule value | ACI | Therapeutic evaluation |
