According to FAO (2011), by 2050, compared with 2010, the demand for meat products will increase by 58%, and the demand for dairy products - by 70%. Livestock farming is known to be one of the most productive sectors, with 35% of world production and 75% of agricultural production spent on developing this industry. Also, this industry consumes 8% of the world's drinking water (including food crops) International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 4 (2020) Journal homepage: http://www.ijcmas.com This article analyzes the synthesis of the Tenebrio molitor protein (Coleoptera: Tenebrio nidae) belonging to a feed insect, depending on its nutrient content. Differences in protein synthesis by Tenebrio molitor larvae were shown when wheat bran and flour from the macrophytes Lemna minor and Azolla carolina were added. In particular, it was noted that TMO-2 and TMO-6 T.molitor F 6 larvae are synthesized on average 31.02% protein in wheat bran, 38.13% in duckweed and 30.87% in azole. It was found that the larvae of variant F 6 grown on wheat bran synthesized protein on average 4.79% less than the variant F 1 of wheat. F 6 larvae grown in duckweed synthesized 7.11% more protein than larvae grown in wheat bran and 0.15% less protein synthesis than larvae grown in azole. It was found that F 6 larvae grown in duckweed produce 7.26% more protein than larvae grown in azole. Summarizing these indicators, it was noted that in the body of larvae eating macrophytes insufficient absorption of nutrients, low moisture content in the feed led to their death, egg laying and larvae of variant F 6 produced significantly less protein than variant F 1 . When feeding macrophytes, it is advisable to take into account its moisture content or add flour based on them to other food sources. It was studied that egg-laying larvae grown on the basis of azole accounted for 38.14%, whereas in duckweed this indicator was 58.38%. It was found that in larvae grown on wheat bran, the percentage of egg-laying is 68.85%. The mortality rate of larvae feeding on wheat bran was 18.22%, in duckweed - 44.63%, in azole - 62.27%, this is due to insufficient moisture in the composition of duckweed and azolle (average humidity 3.4-4.2%), relatively high humidity (average humidity 9.58-10.12%) in wheat bran.
