At present, salanganes houses are built in 43 cities and provinces. Some provinces have salanganes house construction speeding rate of 10 percent – 12 percent every months like Rach Gia town and ha Tien of the Mekong delta province of Kien Giang, Phan Rang – Thap Cham in the central province of Ninh Thuan, Phu Yen, Binh Thuan.
Kien GIang province has over 1,000 salanganes houses while Phu yen has over 800 ones; An Giang with 650 ones; Quang Nam, Da Nang City with 410 each and Binh Thuan with 750 ones.
Though the Ministry of Agriculture and Rural Development has not released the official number of salanganes houses, experts estimated that over 11,000 salanganes houses had been built for breeding the birds.
Bird farmers grasp the salanganes raising techniques more; hence their slanginess houses attract bird quickly than before with the success rate of 70 percent – 80 percent compared to 20 – 40 percent in 2015.
The swift-breeding industry has developed quickly in Vietnam, mainly in southern provinces and cities. Nearly VND18 trillion ($772.7 million) had been poured into the industry with a total of around 7.5 million birds producing nearly 70 tons of nest in 2017 and it is expected to 85-90 tons by 2018.
Vietnamese people now consume over 100 tons a year and the bird nest quantity is equal to the demand including that from Malaysia, Indonesia, Thailand and Cambodia. Raw swift nest is priced at VND22 million per kilogram.
In the end of July, 2018, a group of Vietnamese enterprises arrived in Malaysia to learn about technique to clean bird nest and build standard warehouse to produce good quality bird nest for Chinese market.
