Meat Consumers’ Opinion Regarding Unhealthy Pigs: Should They Be Treated with Antibiotics or Euthanized on Farm?
Abstract
:1. Introduction
2. Materials and Methods
2.1. Participant Recruitment
2.2. Description of the Survey
Pigs that have, or are suspected of having injuries or illnesses (e.g., diarrhoea or respiratory infections) are usually housed in a place called a “hospital pen”, isolated from healthy animals. The goal is to improve their condition and to avoid infecting healthy animals.These pigs remain in the “hospital pen”, not only to allow them to recover but also because of the difficulty that producers have in correctly discarding the euthanized pigs on the farms.The percentage of pigs that enter the “hospital pen” is very low, not exceeding 1% of the herd. However, these animals tend to suffer from their injuries or diseases, receive antibiotics, and have a high probability that their meat can not be used, representing an economic loss for the farm.
