Common diseases encountered in the breeding stock of pigs.

Common diseases encountered in the breeding stock of pigs. In order for pig producers to be successful, keeping their animals healthy is key. It is essential to know about diseases that may occur in the herd and all staff working with the pigs should be able to spot the symptoms of common diseases and alert the manager or veterinarian, as appropriate. Treating pigs quickly with suitable medication is the next step as prevention is obviously better than cure. There is a need to have a herd health plan will help to minimize disease incidence. #breeding #pigs. In terms of disease prevention, re-occurring themes include hygiene, ventilation and reducing stress. Pig producers need to provide an environment that is optimal for the animal and inhospitable for disease-causing agents. As well as reducing infection pressure, immunity must be promoted by measures such as optimal nutrition and good husbandry. Maintaining good biosecurity through every part of the production cycle will go a long way to preventing disease outbreaks. Managers should also ensure that breeding stock are purchased from high health status herds and suitably quarantined before introduction. #breeding stock Common diseases encountered in the breeding stock of pigs. 1) Mastitis Reduced milk production, loss of appetite and a higher body temperature are symptoms of mastitis in sows. It is caused by a bacterial infection of the mammary glands, where skin discoloration can be seen. Antibiotics, along with anti-inflammatory drugs are effective treatments. Oxytocin may be used to encourage let down of milk and corticosteroids can be prescribed. Hygiene in farrowing housing is important, along with nutrition during late pregnancy to promote immunity. Stress can also be a factor, and it is important to make sure that teats are not being damaged by sow housing facilities. This disease has a significant effect on productivity because of the potential effect of reducing the number of piglets weaned by sows. 2). Porcine parvovirus If pregnant sows become infected with parvovirus (PPV), reproductive disease can occur, but not in all cases. If it does, most commonly in gilts, reproductive performance is significantly affected. Mummification and stillbirths occur, resulting in small litter sizes. Other reproductive diseases have the same symptoms so accurate diagnosis is essential. Unusually, the virus can survive outside the host for several months, making it endemic in most herds. Although it is only during pregnancy that PPV is a problem, other pigs can spread the virus. There are no treatments available; in order to prevent this disease routine vaccination of gilts is advisable.
