Babies may be born in any season, after a gestation period of 5 months. Females can have two litters per year. Twins are the most common, although a single baby or triplets are also possible. Babies weigh 1 pound at birth. The entire herd will defend the youngsters against predators or perceived dangers, so keep your distance if there are babies in the herd. Right now we have twins that are about 12″ long and are probably a week old. The most curious in the herd are the adolescents. They want to investigate everything in their environment.
Chiefly vegetarian, half of their diet is comprised of prickly pear cactus which supplies not only food but water, but they also eat roots, fruit, grasses, mesquite beans, palo verde beans, sotol, nuts, and other succulent vegetation including many landscaping plants. Dusk and early morning are their favorite times to feed when the weather becomes hot although they can come around at any time of the day or night. Like many wild animals, they can lose their fear of people and become more of a threat, so we ask that you keep your distance and treat them like the wild animals they are. Already the herd here connects people with food, so they sometimes approach to see what you might have for them.
A herd at our Tucson Arizona B & B is a threat to small dogs, but our cats know them well and are desert wise. They even tease the pigs and then jump up on the wall to escape and gloat. The babies make a sound not like a pig but like the quack of a duck. It is hard not to try and pet them, but mother would let no one near, and they must retain their wildness for their own safety.
