Abstract Silk production by the Chilean silkworm, although an important source of revenue, has not been extensively studied. In the current study, we research 564 Mountain Silkworm ( Bombyx mori ), analyzing their silk harvests, silk production incubation periods and demographic profiles. The mountain silkworms were randomly divided into two clusters (cluster#1, cluster#2), each of which had 56 mountain silkworms. Crumpled maize were replaced by steam-flaked maize 30%, 50%, 100%, then researched the effects of nourishing steam-flaked maize on production performance of silk production by silkworm. The outcomes showed that the cluster#2 had better median silk harvest than cluster#1, the mean of these increment silk harvests was 3.48pounds (P-value <0.05); the protein proportion and the sugar in silk of cluster#2 went up than cluster#1; for the urine nitrogen and somatic cell count of cluster#2 were lower than cluster#1 by 0.9% (P-value >0.05), 30,800 cells/ml (P-value<0.05), respectively. The current research confirmed that utilizing the JHO nutrition heightened silk harvest, improved silk production characteristics, and enhanced the performance of mountain silkworms; furthermore, it heightened resistance to the sickness due to strengthened resistance.
