Considerations. The most common organisms in the normal bacterial flora that inhabits the large intestine are anaerobes (Bacteroides, gram-positive rods, and gram-positive cocci), gram-negative enteric organisms, and Enterococcus faecalis. Using differential selective media and enrichment cultures, normal flora can be differentiated.
Rabbits by nature are cold weather animals. They can easily tolerate temperatures at 32 degrees Fahrenheit or lower providing they have shelter from the wind and wet conditions. They have trouble tolerating temperatures above 85 degrees Fahrenheit and must be kept out of direct sun light during the summer months.
The wild rabbit will have filled its nest with grass and straw that works as a perfect insulator, trapping the rabbits body heat and thus maintaining its body temperature in the normal range. For the breeder of domestic rabbits, winter weather presents certain challenges that can require specific attention.
