Study finds sorghum can replace cassava in Pangasius feed in Vietnam

A primary ingredient used in catfish feeds in Vietnam is cassava. However, the current production level of cassava is not enough to supply the growing demand. According to a study sponsored by the USGC, sorghum is one potential ingredient to substitute for cassava as a source of starch for feeding Pangasius in Vietnam. Sorghum contains a reasonable amount of protein (10%), higher than cassava, and also contains higher amino acids, similar to corn but relatively higher in tryptophan and threonine.

According to the US Grains Council (USGC), catfish production in Vietnam was estimated at 1.2 million tons in 2014, which required approximately 2.4 million tons of feed.

A primary ingredient used in catfish feeds in Vietnam is cassava. However, cassava is in high demand locally, and the current production level of around 7 million tons is not enough to supply the growing need for feed for catfish and swine, as well as uses for biofuel. 

According to a study sponsored by the USGC, sorghum is one potential ingredient to substitute for cassava as a source of starch for feeding Pangasius in Vietnam. Sorghum contains a reasonable amount of protein (10%), higher than cassava, and also contains higher amino acids, similar to corn but relatively higher in tryptophan and threonine.

During the study, which took place at the research farm of a private company in Vietnam, grain sorghum from the United States was imported and analyzed for chemical composition and amino acids content. Sorghum was then included in a diet formulation. The sorghum diet was compared to a cassava-based diet and corn-based diet during a 120-day feeding trial.

Results found that U.S. sorghum, can be successfully fed up to 20% in the diet of Pangasius to replace cassava and similar to a corn diet at 10% inclusion rate.
