Black soldier fly larvae are converters of organic waste into edible biomass, which the composition may depend on substrate. In this study, were grown four substrates: chicken feed, vegetable waste, biogas digestate, and restaurant waste. Samples prepupae substrates freeze-dried proximate, amino acid, fatty acid mineral analyses performed.Protein content varied between 399 431 g kg-1 dry matter (DM) among treatments. Differences in profile small. On other hand, ether extract (EE) ash...

Abstract BACKGROUND: The essential oils (EO) carvacrol, thymol, eugenol and trans ‐cinnamaldehyde have well‐documented antimicrobial properties offer therefore an alternative for the growth promoters in pig feeds. aim of this work was to determine degradation kinetics these EO along gastrointestinal tract (GIT) piglets, which is necessary information correct application RESULTS: None compounds significantly degraded vitro simulations gastric fermentation. Carvacrol thymol were not jejunal...

Creatine, (CREA) a central constituent in energy metabolism, is obtained from dietary animal protein or de novo synthesis guanidinoacetic acid (GAA). Especially all-vegetable diets, supplemental CREA GAA may restore the availability tissues, and hence, improve performance. In this study, 768 one-d-old male Ross 308 broilers were assigned to 1 of 4 diets: negative control, corn-soybean-based; control supplemented with either 0.6 1.2 g per kilogram feed; positive (60, 30, 30 g/kg fish meal...

Two trials were conducted to study the effects of dose and formulation carvacrol thymol on bacterial counts, metabolites functional traits gut in weaned piglets. In first experiment (Exp. I), 25 piglets (28 d, 6.59 ± 0.48 kg BW) allocated five dietary treatments: a control diet, or same diet supplemented with either at doses 500 2000 mg kg−1. second II), 35 7.99 0.73 assigned seven as Exp. I, this one three formulations (on celite, alphacel microencapsulated) At 11/12 days post-weaning...

The digestive function of low birth weight (LBW) pigs post-weaning has been poorly studied. Therefore, newborns from eleven hyperprolific sows were weighed, weaned at 27·2 d and fed a starter diet until sampling. Sampling was done between 18 28 post-weaning. An LBW piglet (n 19) defined as having less than 1 kg the lower quartile litter weights. Normal (NBW) piglets 13) close to mean weight. For each piglet, eighty-eight variables determined. Data analysed with linear models type predictors....

Oxidative stress in the small intestinal epithelium is a major cause of barrier malfunction and failure to regenerate. This study presents functional vitro model using porcine epithelial cell line IPEC-J2 examine effects oxidative estimate antioxidant regenerative potential Trolox, ascorbic acid glutathione monoethyl ester. Hydrogen peroxide diethyl maleate affected tight junction (zona occludens-1) distribution, significantly increased intracellular (CM-H2DCFDA) decreased monolayer...

Although oat (1,3:1,4)-b-glucan (BG) has been shown to decrease blood cholesterol in intervention trials, the detailed mechanism is not yet defined, but restricted reabsorption of bile acids (BAs) hypothesized.Using pigs as a model for humans we demonstrated that, compared control, BG added diet 26 d caused decreases 24% total BAs (TBAs), 34% (TC), and 57% LDL (LDL-C) (P < 0.01); 20% TBA midjejunum terminal ileum increases 80% cecal neutral sterols (TNSs) including 50% reduction BA active...

Insects are promising candidates as alternative sustainable sources of protein for poultry species. The present research studied the effect a dietary inclusion defatted black soldier fly (BSF) larvae meal an source in diets laying quails, on productive performance, egg physicochemical quality, fatty acid profile, sensory traits and storage stability. A total 225 quails were divided into 3 groups (5 replicates/each). conventional soybean meal-based diet was formulated (Control group), two...

Functional amino acids supplementation to farm animals is considered not only be beneficial by regulating intestinal barrier, oxidative stress, and immunity, but potentially also impacting the gut microbiota. The impact of on a piglet-derived colonic microbiota was evaluated using 48-h in vitro batch incubation strategy. combination 16S rRNA gene profiling with flow cytometry demonstrated that specific microbial taxa were involved fermentation each resulting production metabolites. Branched...

Heat stress in poultry is a serious problem many countries and has been associated with oxidative stress. Hence, nutritional interventions antioxidants might be beneficial. Therefore, the effects of dietary Curcuma xanthorrhiza (CX) Origanum compactum (OC) essential oils on mRNA levels heat shock protein 70 antioxidant enzymes, status, meat stability heat-challenged broilers were studied. Starting d 25 age, control diet 4 diets containing 200 or 400 mg/kg feed CX OC (CX200, CX400, OC200,...

Neonates with intrauterine growth restriction (IUGR) show lower efficiency of nutrient utilization compared to normal birth weight (NBW) newborns. This study was conducted using neonatal piglets as a model test the hypothesis that IUGR affects intestinal barrier function, structure, and antioxidant system development during suckling period. The small mucosae were obtained from NBW littermates in period (d 0, 3, 8, 19 postnatal). epithelial function assessed by FITC-dextran 4 (FD4)...

Summary The aim was to assess the effects of intact dried Ascophyllum nodosum seaweed on piglet performances, gut bacteria and function plasma oxidative status. A total 160 weaned piglets (21 days, 6.59 ± 0.91 kg) were allocated four dietary treatments with eight pen replicates five animals each for 28 days: a control diet; based cereals, soybean meal milk products, three basal diets supplemented either 2.5, 5.0 or 10.0 g per kg. At day 12/13 one from sacrificed. Plasma samples taken...

1. Fermented feed has been shown to be beneficial in pig nutrition as a tool reduce gut microbial disorders. Experiments with fermented poultry are scarce, probably because of the belief that wet is less suitable for this species and causes litter. 2. A total 280 one-d-old Ross 308 chickens were used completely randomised design two dietary treatments (7 replicates 20 birds/treatment); air-dry versus same moist form (water:feed ratio 1.3:1, on weight basis), inoculated Lactobacillus...

Summary The negative effects of high ambient temperature during some months the year on poultry production have been great concern in many countries. Dietary modifications are among most practical ways to alleviate temperature. Possible dietary supplementation with 200 or 400 mg/kg feed lemon peel extract ( LPE ), orange OPE ) and Curcuma xanthorrhiza essential oil CXEO under hot conditions (34 °C 50% relative humidity for 5 h daily starting from day 28 until 38 age) blood antioxidant enzyme...
