Tropical Plant Phytonutrient Improves the Use of Insect Protein for Ruminant Feed (original) (raw)

This work aimed to examine the effects of binding proteins from Gryllus bimaculatus with Sesbania grandiflora phytonutrient on gas dynamics, in vitro digestibility, and ruminal fermentation characteristics. For rumen fluid sources, two dairy bulls with permanent cannulas were used as donors. G. bimaculatus and S. grandiflora powder were combined in the following ratios: 100:0, 99:1, 98:2, 97:3, 96:4, 95:5, 94:6, and 93:7. As 7% of S. grandiflora and 3% of G. bimaculatus were combined, the rumen undegradable protein increased by 45.8% when compared to the control group (p < 0.05). All gas kinetics were not substantially different across treatments, except for cumulative gas output during 96 h of incubation (p < 0.05). Comparing the G. bimaculatus powder to S. grandiflora at a ratio of 95:5 to 93:7 revealed an increase in cumulative gas production (p < 0.05), compared to the other groups. Reduction of G. bimaculatus resulted in a linear increase of in vitro dry matter digesti...
