Prevention and control of livestock parasites II - SS3 Agriculture Past Questions and Answers - page 2
Which management strategy involves resting and recovering pastures after grazing?
Quarantine
Continuous grazing
Rotational grazing
Antibiotic treatment
In parasite control, what is the primary concern with the misuse of deworming chemicals?
Improved drug efficacy
Development of drug resistance
Decreased animal growth
Increased pasture productivity
What can result from continuous grazing without pasture rotation?
Healthier pastures
Reduced parasite exposure
Soil erosion
Increased animal weight
Which of the following is NOT a benefit of using chemicals for parasite control?
Rapid parasite elimination
Reduced environmental impact
Convenience of administration
Improved animal health
What should be considered when deciding the timing of deworming in chemical parasite control?
Animal color
Local weather patterns
Animal names
Farm location
Explain the concept of drug resistance in the context of parasite control.
Drug resistance occurs when parasites develop the ability to survive exposure to deworming chemicals, rendering these chemicals less effective over time.
What are some environmental benefits of using rotational grazing in parasite control?
Rotational grazing can promote healthier pastures, reduce soil erosion, and enhance biodiversity, leading to positive environmental impacts.
Describe a situation where rotational grazing might not be a practical method for parasite control.
In densely populated livestock areas with limited available land, it may be challenging to implement rotational grazing effectively.
How can veterinarians help in the management of parasite control on a livestock farm?
Veterinarians can provide guidance on deworming schedules, perform fecal egg counts to assess parasite levels, and recommend suitable parasite control strategies.
What are some potential risks associated with the improper use of deworming chemicals in livestock management?
Improper use of deworming chemicals can lead to drug resistance in parasites, harm non-target species, and contaminate the environment, posing risks to both animals and ecosystems.
