List effects of ectoparasite infestation on livestock, factors affecting pasture productivity, plant characteristics for pasture, cannibalism factors in layers, and maize storage pests.

You're on a roll — here's the answer to question 1: 1. (a) i) Five effects of ectoparasite infestation on livestock are: • Reduced growth rate • Decreased milk or meat production • Damage to hides and skins • Transmission of diseases (e.g., tick-borne diseases) • Anaemia (due to blood feeding) 1. (b) i) Five factors which could affect the productivity of pastures are: • Soil fertility • Rainfall/Water availability • Temperature • Grazing management (e.g., overgrazing) • Presence of pests and diseases ii) Four characteristics of plants which make them suitable for pasture development are: • High palatability (readily eaten by livestock) • High nutritive value • Rapid regrowth after grazing • Tolerance to trampling 1. (c) Four factors which could facilitate cannibalism among layers are: • Overcrowding • Nutritional deficiencies (e.g., lack of protein or salt) • High light intensity • Lack of enrichment or boredom 1. (d) Two storage pests of maize are: • Maize weevil (Sitophilus zeamais) • Larger grain borer (Prostephanus truncatus) What's next?
