oasted Guar Korma is a high

protein raw material, obtained

after extraction of Guar gum from

the seeds of the leguminous plant

Cyamopsis tetragonoloba. It is cleaned androasted after the gum extraction to remove

anti-nutritional factors present in korma,

such as trypsin inhibitor, improving its nutri-

tional values and total digestibility.

The product is obtained without added

chemicals or preservatives and is completely

GMO free, which can be an important factor

to replace soybean meal.

Roasted Guar Korma is thus a competitive

alternative for soybean meal, but there is little

information about its use in Aquafeeds.

Experiment:3 experimental diets were produced: one

reference diet, a diet with 5 per cent Roasted

Guar Korma and a diet wiht 10 per centRoasted Guar Korma. Feeds are produced

with a pellet mill on a 2 mm die, using

preconditioning with steam (>90C) and

postconditioning (>90C) during 20 minutes.

Roasted Gur Korma replaced 50 per cent

soybean meal and 50 per cent Chilean Fish

meal to obtain the same protein levels in all

feeds.

Shrimp trialThe shrimp trial was conducted at the

CreveTec-AFT Research station in Venray.

The trial started with shrimp (Litopenaeus

vannamei, Shrimp Improvement Systems) of

+2,5 g and lasted for 4 weeks.

There are 4 replicates for each diet, so 12

tanks of 150 l in total. Each tank received 30

shrimp. All tanks are connected to a bigger

tank. This way, all tanks have the same water

quality. Water quality in the big tanks is main-

tained with bioflocs.

Feed gift is adapted daily according to

the average weight of shrimp, biomass and

expected growth.

Each week, shrimp were counted and

weighed together to have average weight and

total biomass.

Results:Initially, growth of feeds with RG were

showing better growth, but this did not

continue during the whole 4 weeks. We can

observe that the feed with 10 RG has a little

less growth, and this difference is statistically

different.

The FCR was statistically higher for the

feed with 10 per cent RG, but differences

are very small and all FCR observed are very

good.

Conclusions

We can safely conclude that 5 per cent

Roasted Guar Korma can replace 2,5 per

cent soybean meal and 2,5 per cent fish meal

in feeds for Shrimp (Litopenaeus vannamei),

which is an important result, because it will

be an important cost saving for the shrimp

feed producer. Also 10 per cent inclusion

rate is possible, but then there might be a

very low effect on growth and FCR. Roasted

Guar Korma is also a valuable alternative for

soybean meal in case the producer wants to

guarantee GMO free production.
