BULACAN, Philippines - Health authorities in Bulacan province have started monitoring hog farms amid reports of an outbreak of porcine diarrhea in the area.
Radio dzBB's Bernie Morales reported that the provincial veterinary office in Bulacan coordinated with hog dealers to keep an eye on the health of pigs they sell.
But provincial veterinary office head Dr. Felipe Bartolome said hog dealers should not use the potential hog supply shortage as an excuse to raise prices of pigs.
He said, however, that his office is mapping out plans to prevent the spread of the disease among swine.
In 2007, an outbreak of hog cholera prompted health officials to declare a “red alert" in Bulacan and nearby provinces.
An article on porcine epidemic diarrhea at The Pig Site said the virus that causes the disease damages the villi in the gut, reducing the absorptive surface, which could cause dehydration.
But after introduction of the virus into a susceptible breeding herd, a strong immunity develops over two to three weeks. The colostral immunity then protects the piglets.
Symptoms in sows include mild "cow pat" feces and loose feces to a watery diarrhea.
Diarrhea, dehydration, and a possibly high mortality are among the symptom in piglets.
Signs of the disease in weaners and growers include acute watery diarrhea with no blood or mucus, low mortality but high morbidity, rapid spread of diarrhea across all breeding and growing pigs with almost 100% morbidity (pigs affected) within five to 10 days and vomiting. - GMANews.TV
