(a) State four ways of controlling specimen G (Rat) on an animal farm.
(b) State four effects of specimen H (Tick) on cattle.
(c) Mention three other organisms which have similar effects as specimen H on farm animals.
(d) State four ways of controlling specimen H.
Explanation
(a) Ways of Controlling Specimen G (Rat);- Use of traps. -Use of rodenticides/poisons/pesticides. -Good farm sanitation. -Storage of farm inputs in covered containers. -Use of wire mesh. -Block all openings on walls/floors/roofs. -Use of predators e.g cats.
(b) Effects of Specimen H (Ticks) on Cattle;-Cause of irritation/annoyance/restlessness. -Are vectors of diseases, e.g babesiosis, theilerioses, heartwater disease, tick fever, anaplasmosis. -Injuries from their bites cause secondary infection. -Bites cause damage to the quality of skin/rough skin. -They cause anaemia/loss of blood. -Reduce productivity e.g growth,milk. -It can cause lameness. -It can lead to death.
(c) Organisms which Cause Similar Effects as Specimen H (Tick) on Farm Animals; -Lice. -Mites/keds. -Fleas. -Larvae of housefly/blowfly.
(d) Ways of Controlling Specimen H (tick);-Good sanitation/farm hygiene. -Rotational grazing/paddocking. -Application of acarides/pesticides/dusting/dipping/spraying/pour-on. -Isolation of infested animals from others/quarantine. -Hand picking of ticks from te animal's body. -Burn infested pasture/grazing lands. -Natural control. -Use of predators e.g birds.
