Ten percent of the poultry populations, including fighting cocks in Central Negros, are greatly affected by stress due to heat-related conditions affecting the animals, Dr. Renante Decena, provincial veterinarian, said yesterday.
PVO reports show that backyard poultry breeders in the towns of San Enrique and Valladolid and in the cities of Bago and Talisay are greatly affected by heat stress due to the increase of body temperature of the animals.
He said the average body temperature of a fowl is 49°Celcious and if the environment heat exposure is greater than its body temperature, the animal suffers heat stress that may lead to heat stroke.
Negros Occidental has a total population of about six million backyard populations of fowls and if this is affected by heat stress, the egg production of layers will be affected, and may cause a drop in supply, Decena said.
To mitigate the hot temperature, breeders have to give the animals more water with electrolytes to prevent dehydration, he said.
They have to be cautious also about bacteria like salmonella and e-coli that reside in the oropharynx of chickens, pigs, and carabaos that cause more stress to the animals and can lead to respiratory problems, Decena also said.
Breeders must also reduce the number of animals in a cage to increase ventilation and if possible, they must use heat insulator materials for their housing like nipa or cogon, he said.
PVO medical mission team is also visiting remote areas to conduct veterinary health inspections and vaccinations of animals to prevent the spread of diseases, Decena added. *LTG
