A simple method for identifying diseased pigs
1. Look at the eyes. In healthy pigs, their eyes are bright and bright, and it is a sign of illness if they are found to have dark, red and excessive droppings.
2. Look at the skin. Healthy pigs have smooth and round skin and plump muscles, such as rough and inelastic pigskin, with swelling, ulcers, erythema, rotten spots and so on.
3. Look at the coat color. Healthy pigs, the coat color is bright and shiny, if the pig hair is rough, inelastic and messy, it is a sign of illness.
4. Look at the nasal plate. In healthy pigs, the nose plate is wet with sweat balls; if the pig nose plate is dry without sweat beads, and there is a large amount of mucus overflow in the nostrils, it is a sign of illness.
5. Look at the action. Healthy pigs have a constantly wagging tail and can respond quickly and sensitively to external stimuli. Healthy adult pigs are gluttonous and sleep. If you give food, you will come in response. When you are full and sleepy, when a stranger approaches, you will stand up and raise your eyes and keep shaking your tail. If there is a sagging head and tail and other phenomena, it is a sick pig.
6. Look at the neck. In healthy pigs, the head and neck move freely and there is no swelling and stiffness; if the head and neck of the pig is uncomfortable or swollen and stiff, it is a sign of illness.
7. Look at breathing. In healthy pigs, normal breathing is 10-20 times per minute; it is abnormal if abdominal breathing is too fast or too slow.
8. Look at the tail. In healthy pigs, the anus is clean and free of feces; if it is found that the pig anus and its surroundings, or even the tail adhered to thin feces, or anal rectal prolapse or tail prolapse does not move, it is a manifestation of the disease.
9. Look at the posture. Healthy pigs sleep on many sides and breathe with chest and abdomen breathing (depending on the situation, there is also abdominal breathing). If the dog is sitting and breathing with open mouth, it is a sign of illness.
10. Listen to the sound. A healthy pig makes a loud cry; if it is hoarse, it is a sick pig.

Petrand pig
Petland pigs are produced in Belgium. The body is square, wide and short, with thin bones and short limbs and well-developed muscles. The hair is gray with black patches and the ears are moderately forward. The average litter size is about 10 piglets. It is reported that 90kg body weight growth fat has a carcass lean rate of 66.9%, a daily gain of 700g, and a feed efficiency of 2.65. The growth rate of commercial pigs decreased significantly after 90kg. Petland pigs have a severe stress response, and about 50% of pigs have halothane recessive genes. It is easy to appear gray meat after crossing with purebred Petrand as male parent.
