Identify and describe the function and economic importance of common farm parasites and laboratory instruments.

You're on a roll — Here are the answers to questions 2 and 3: Question 2: a) Identify the parasites. The parasites are roundworms (or nematodes). b) State three (3) methods of controlling the parasites. Regular deworming* of farm animals. Maintaining good sanitation and hygiene* in animal housing and grazing areas. Practicing rotational grazing* to break the parasite life cycle. c) State three (3) economic importance of the parasites. Reduced growth rate* and weight gain in infested animals. Decreased production* of milk, meat, or eggs. Increased veterinary costs* for treatment and prevention. d) Name four (4) farm animals that can be infested by this parasite. Cattle* Sheep* Goats* Pigs* e) i) State the type of parasites the figure belong. The parasites are endoparasites. e) ii) Mention any three (3) parasites that belong to the type in e(i) above. Tapeworms* Flukes* Coccidia* (a protozoan endoparasite) Question 3: a) Identify the instruments labelled A, B, C, D, and E. A: Hydrometer* B: Conical flask* (or Erlenmeyer flask) C: Thermometer* D: Pipette* (specifically, a volumetric or transfer pipette) E: Measuring cylinder* (or graduated cylinder) b) State one (1) use of each of the following instruments A, B, C, D and E. A (Hydrometer): Used to measure the relative density or specific gravity* of liquids. B (Conical flask): Used for mixing, heating, and storing solutions*, often in titrations. C (Thermometer): Used to measure temperature*. D (Pipette): Used to accurately measure and transfer a precise volume of liquid*. E (Measuring cylinder): Used to measure approximate volumes of liquids*. c) Describe how instrument D is used. To use instrument D (a pipette), a pipette filler or bulb is attached to the top. Liquid is drawn into the pipette by suction until its meniscus reaches the calibration mark. The liquid is then carefully released into another container, typically by removing the filler and allowing it to drain by gravity, ensuring the last drop is delivered for accurate volume transfer.
