This document addresses what is known about flu viruses in pigs and people and what people in contact with pigs can do to reduce the risk of getting sick or of getting their pigs sick. There are many causes of respiratory disease in pigs, including influenza. Among influenza types, only type A influenza viruses are known to infect pigs. Most of the influenza viruses circulating in swine are different from those circulating in people. At this time, there are three main flu viruses that circulate in U. These viruses do not usually infect people and are genetically different from the H1N1 and H3N2 viruses that commonly circulate in people. When the flu viruses circulating in pigs are very different from the human flu viruses causing illness in people, people may have little to no immune protection against the viruses circulating in pigs. Also, human flu vaccines probably would not offer protection against the viruses that are found in pigs. Flu viruses commonly infect pigs and pig herds and can result in high rates of illness among pigs, but few deaths.

Sows and gilts are nonseasonal and polyestrous, with the estrous cycle lasting 18—24 average 21 days. Sows are behaviorally anestrous during pregnancy. Ovulatory estrus usually is not seen during lactation except under conditions of group rearing, high feed levels, or boar contact.

Skip to content Ontario. Explore Government. The pork industry continues to look for ways to improve pork safety and quality, production performance, animal welfare and the environment. One of the good production practices recognized by the pork industry is withdrawing feed from market hogs prior to slaughter. Pork producers are encouraged to work with hog transporters and packers to implement an effective on-farm feed withdrawal program.
Pre-slaughter feed withdrawal also referred to as withholding feed, removal of feed, holding feed off or fasting prior to slaughter is the period of time when pigs are denied access to feed prior to slaughter. To calculate the number of hours of feed withdrawal, the overall time from feed removal to slaughter must be considered. For example, if feed is withdrawn from pigs at pm, and they are slaughtered at am the following day, the total time of pre-slaughter feed withdrawal is 15 hr.
The timing of feed withdrawal is critical to the success of a feed withdrawal program. Numerous studies have shown that the optimal pre-slaughter feed withdrawal time is hr. To properly assess the timing of feed withdrawal, monitor the feeding cycles in the barn so you know when the majority of pigs have last eaten. Researchers in Illinois studied the eating behaviour of market hogs and found that un-crowded pigs ate little feed overnight between pm and am.
However, where pigs were crowded or housed in hot barns, feeding was more likely to continue throughout the night. The pigs’ housing situation can affect how long they may have gone without feed by morning.

John C. Kinsey, CWB. The Feral Hog in Texas was written by Rick Taylor, Wildlife Biologist as an informative booklet describing the feral hog and control practices. Feral hogs Sus scrofa are an old world species belonging to the family Suidae, and in Texas include European wild hogs, feral hogs, and European-feral crossbreeds. Feral hogs are domestic hogs that either escaped or were released for hunting purposes.
With each generation, the hog’s domestic characteristics diminish and they develop the traits needed for survival in the wild. Early Spanish explorers probably were the first to introduce hogs in Texas over years ago. As colonization increased, hog numbers subsequently increased. They provided an important source of cured meat and lard for settlers.
During the fight for Texas independence as people fled for safety into the United States or Mexico, many hogs escaped or were released. It was not until the mid s when hostilities between the United States and Mexico ended that settlers once again began bringing livestock back into Texas.

The most critical period in the life cycle of a pig is from birth to weaning. is designed to help producers determine farrowing date based on the date sows are bred. There are many good sources of iron that can be used to prevent anemia.
Sows are pregnant for three months, three weeks and three days days; normal range to days measured from the first day of mating service. A sow expelling piglets before days should be classed as an abortion, and any piglets born between and days as a premature farrowing. Variation in pregnancy length can be due to age, environmental conditions, specific breed, or time of the year. During pregnancy, it is ideal to keep the sow in a familiar routine, including her normal feed ration, to minimise stress and increase the implant rate of the fertile eggs.
The viable foetuses secrete the pregnancy maintenance hormone progesterone, informing the sow she is pregnant. Newly-pregnant sows should not be mixed with new pigs without gentle introduction. She can remain in her existing group right through to farrowing, but the other pigs are likely to show a lot of interest and increase the chances of her piglets being squashed.

Raising quality livestock for junior fairs and shows requires a combination of both a good feeding and animal health program, as well as good overall management. These programs should not be treated as separate subjects, particularly when feeding market hogs. When you have a market project animal, you must also remember you are raising a food animal and your goals should include producing a safe, wholesome and high quality product for consumers.
The first step in producing a quality end product is the selection of a healthy feeder pig with good growth potential. Selecting a feeder pig in the right weight range for your market swine project is critical.

Aggression in pigs occurs as a natural behaviour when stablishing hierarchy after mixing unfamiliar animals. It goes from threats or non-contact aggressive encounters to contact aggressions which can provoke lesions. As mixing may occur several times in pig farming, aggressions can happen in repeated occasions with negative welfare consequences for the pigs such as distress, injuries and sometimes even death.
For improving pig welfare, strategies to prevent or reduce aggressions should be implemented in pig farms. Pigs are gregarious animals and the social structure is based in the dominant-subordinate relationship to establish hierarchy. The reason behind this social organisation is to establish an order of access to resources when these are limited. The formation of hierarchy is based on the dominance-subordinate relationship and it occurs right after mixing of unfamiliar animals, lasting from 24 to 48 hours.
Pigs use aggression to establishes the dominance-subordinate relationship. Therefore, fighting occurs especially during mixing of unfamiliar animals. Scarcity of key resources such as feed, water or space to rest will facilitate competition and fights. For example, when feed is limited, this will be first accessed by dominant pigs and followed by its subordinates.
In a group of pigs, once hierarchy has been established, aggressions will decrease dramatically.
