Final answer:
Harvey's mistake was putting the pigs on a bed of straw that could infect their belly buttons and not ensuring they consume colostrum in the first hours of life.
Step-by-step explanation:
In this scenario, the subject is pigs and their care in the early stages of life. The mistake Harvey made was putting the pigs on a bed of straw that could infect their belly buttons, as well as not ensuring that they consume colostrum in the first hours of life.
Colostrum, also known as the first milk, is extremely important for newborn pigs as it provides them with essential nutrients and antibodies to build their immune system. It is rich in proteins, fats, vitamins, and minerals.
Additionally, keeping the pigs on a clean and sterile bedding, such as heat-treated wood shavings or rubber mats, can prevent infection and promote healthy growth.
