  2. Lactating dairy cattle

  1. Pregnant cattle

  1. Sheep reared for wool production

  1. Heifers

  1. “In poultry production, culling may sometimes be essential if the profits are to be optimized.” Explain the statement, illustrating your answer with the situations in which this needs to be practiced.
