Comparative Analysis of In Vitro Fermentation Parameters in Total Mixed Rations of Dairy Cows with Varied Levels of Defatted Black Soldier Fly Larvae (Hermetia illucens) as a Substitute for Soybean Meal

چکیده
In this study, we compared the digestibility levels and in vitro fermentation parameters of total mixed rations (TMRs) containing 20% 40% defatted black soldier fly (Hermetia illucens) larvae (BSF) as a substitute for soybean meal (SBM) basal ration (60% roughage/40% concentrated feed) dairy cows. We evaluated volatile fatty acid (VFA), gas production, methane emission, ammonia, pH, carbon dioxide, dry matter (IVDMD), neutral detergent fiber (IVNDFD) TMR0 (basal), TMR20 (20% BSF included), TMR40 (40% included) diets at end 24 48 h incubation. Significantly lower ammonia formation were found groups (p < 0.001). An increase VFA was observed group The highest IVDMD determined h. IVNDFD value substitution SBM with positively affected had cumulative production incubation 0.05). conclusion, use positive impact on rumen fermentation. Therefore, recommend formulating cow rations.

Aim This experiment aimed to evaluate substitution of soybean meal (SBM) by black soldier fly (BSF) larvae meal in a napier grass diet as performed by an in vitro rumen fermentation system. Materials and Methods Samples of napier grass, SBM, and BSF larvae age 1 week (BSF1) and 2 weeks (BSF2) were arranged according to the following dietary treatments (dry matter [DM] basis): T1, 100% napier ...

An 8-week feeding trial was conducted to evaluate effects of replacing fish meal (FM) with black soldier fly larvae meal (BSF) on growth performance, feed utilization, and plasma parameters, for juvenile yellow catfish, Pelteobagrus fulvidraco. Six isonitrogenous and isolipidic diets were prepared substituting the FM protein with BSF protein in the following amounts: 0 (control group), 10% (BSF...

The intra-puparial development of the black soldier-fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), was studied based on 125 pupae under controlled conditions in laboratory. The 6(th) instar larvae were reared until they stopped feeding, and the prepupae were separated according to the reduction in larval length and degree of pigmentation and sclerotization of the cuticle. The pupal stage...
متن کاملModulation of nutrient composition of black soldier fly (Hermetia illucens) larvae by feeding seaweed-enriched media
Black soldier fly (Hermetia illucens) larvae are a promising source of protein and lipid for animal feeds. The nutritional composition of the BSF larvae depend partly on the composition of the feeding medium. The BSF lipid profile in part mimics the feeding media lipid profile, and micronutrients, like minerals and vitamins, can readily accumulate in black soldier fly larvae. However, investiga...
