Chinese broilers go for grasshoppers
Chinese researchers have evaluated grasshopper meal as
a protein source for broiler diets. The meal could be added to the feed at a
rate of 15% with no adverse effects on performance.
On a dry matter basis Chinese grasshoppers (Acrida cinerea
contain 654 grams of crude protein, 83g fat and 87g chitin per kg.
Amino acid content
The researchers found that the content of amino acids compared well with
fish meal; the methionine, cystine and lysine concentrations in the grasshopper
meal were 17, 7 and 38g per kg on dry matter basis respectively.
True amino acid digestibility was determined in cecectomised roosters and
was 0.97 for methionine, 0.84 for cystine and 0.95 for lysine. The
nitrogen-corrected true metabolizable energy (TMEn) of the grasshopper meal was
When maize-insect-soybean meal diets were formulated on an equal CP and
TMEn basis, up to 150 g per kg the grasshopper meal could replace control diet
without any adverse affects on broiler weight gain, feed intake, or gain:feed
ratio from 8 to 20 days post hatching.
The fatty acid analysis showed polyunsaturated fatty acids of the
grasshopper meal to be present in high quantities, and the total content of
oleic, linoleic and linolenic acids was 0.8449 of total fatty acids. The results
indicated that the insect could be an acceptable raw material for feed and
