Pigs

The diaphragm in a fetal pig serves as a crucial muscle that separates the thoracic cavity from the abdominal cavity. During development, it aids in respiration by expanding and contracting, allowing air to flow into the lungs after birth. However, in the fetus, the diaphragm is primarily involved in the development of the respiratory system, as the fetus receives oxygen through the placenta rather than breathing air. Its proper formation is essential for the pig's ability to breathe autonomously after birth.

Only if they are female pigs, called sows.

The largest species of wild pigs is the Eurasian wild boar (Sus scrofa). Adult males can weigh between 150 to 300 pounds and sometimes even exceed this range. They inhabit a variety of environments across Europe, Asia, and North Africa. Known for their adaptability, they have also been introduced to other regions, including North America.

There is no such thing as a hog bear. Even though females are called sows and males boars, just like with domestic pigs, this in no way acknowledge that bears are pigs, are related to pigs or there are so called "hog bears" out there.

Females can get as big as male Guinea pigs which can be up to 2-5 pounds

Record keeping is crucial for sows as it helps track their health, reproduction cycles, and overall productivity, enabling farmers to make informed management decisions. Accurate records can identify trends or issues, leading to improved breeding strategies and reduced costs. Additionally, it ensures compliance with regulations and enhances traceability in the food supply chain. Overall, effective record keeping supports better animal welfare and farm efficiency.

Landrace pigs belong to the genus Sus. This genus includes various species of pigs, with the domestic pig (Sus scrofa domesticus) being a subspecies of the wild boar (Sus scrofa). Landrace pigs are known for their adaptability and are often bred for their desirable traits in agriculture.

Peppa Pig's parents, Daddy Pig and Mummy Pig, are not given specific ages in the series. However, they are depicted as adults, likely in their 30s or 40s, which is a common age range for parents in children's shows. The focus is more on their roles as parents rather than their exact ages.

You can keep your guinea pig in a hutch or a cage.

A two-week-old piglet typically weighs between 10 to 15 pounds (4.5 to 6.8 kg), depending on the breed and overall health. At this age, they are usually about 12 to 15 inches long (30 to 38 cm) from snout to tail. Their bodies are still quite small and delicate, with features like short legs and large ears. Piglets at this stage are growing rapidly, gaining weight as they begin to transition to solid food alongside nursing.

Pigs

The diaphragm separates the abdominal & thoracic (same as in people) cavities.

The brain of a pig includes several key parts: the cerebrum, which is responsible for higher cognitive functions; the cerebellum, which coordinates movement and balance; and the brainstem, which controls essential life functions such as breathing and heart rate. Additionally, the limbic system, involved in emotions and memory, is present. Overall, a pig's brain is structurally similar to that of other mammals, reflecting its complex behavior and intelligence.
