豬的腹瀉

I reviewed this proceedings paper with two of my colleagues at Carthage Veterinary Service, Ltd. Dr. Lowe has an exciting
and challenging perspective on baby pig treatments. The injectable therapies may actually make Clostridium diarrhea worse in those herds that are chronic Clostridium A herds. He has gone so far as to rely more heavily on drying
powders and elevated room temperatures. In fact, evenstopping washing and sanitizing farrowing crates for two full turns of the farrowing house in order to spend time and energy focusing on Day 1 care and colostrum uptake of piglets. Drying powders are used to keep the piglets from chilling, keep the farrowing crates dry, and then individual injections are only given when whole litters are continuing to scour.
Dr. Groth had a similar experience with Clostridium A whereby if it is straight Clostridium A with no other rotavirus or E. coli he will stop all individual treatments, and focus on whole litter swaps followed by the initiation of feedback. When the decision is made to feedback, it is also important to remember this must be done prior to two weeks pre-farrow to initiate immune prevention and not create a more severe diarrhea problem.
Three veterinarians can agree on the fact that the management
procedures are most critical in long-term prevention of neonatal diarrhea. We agree that whole litter swaps are effective and that individual movement of piglets or a great deal of piglet handling and transmission of scouring litters can lead to outbreaks that are management driven.
Increasing room temperature in order to dry the rooms and focusing your farm staffs attention on Day 1 care with split-suckle boxes and colostrum management is the most critical.
Prevention
Long-term prevention includes both the focus on gilt development for these females into your breeding herd with appropriate feedback of fecal material from scouring piglets as well as vaccination programs during the gestation
period. Two vaccinations with an E. coli product and Clostridium if present in your herd will be critical long-term. Several clients have enjoyed success with rotavirus vaccination as part of the gilt development program. However, scientists remind us that the best rotavirus protection is only achieved through oral exposure to the rotavirus organism. This can be accomplished with the live oral vaccination or through the collection of feedback material and timely exposure to both gilts and sows in the event of rotavirus activity in farrowing.
Sanitation is also critical where we are allowing exposure through no washing, but using drying powder to occur in chronic cases, or going to the opposite and allowing farm staff the time necessary to completely sanitize the farrowing
house and follow-up with drying time for individual farrowing crates. This is quite costly in the wintertime when we are trying to dry an empty farrowing room, but also critical in the summer when we are challenged with coccidia and know that humidity and challenging environments
are going to lead to an explosion of this organism within many of our systems.
In final summary, a thorough review of the sanitation and disinfection, an implementation of immunity evaluation of vaccination protocols, as well as the need for intervention
with treatments and management in the farrowing house will lead to a long-term sustainable environment for the piglets and improved piglet survivability in the farrowing house.
