Abstract Background Dietary supplementation of full-fat black soldier fly larvae (BSFL meal; alone or in combination with multi-probiotics) was tested as an alternative to dietary antibiotics weaning piglets. We also the effects these diets on growth performance, nutrient digestibility coefficients, immune status, oxidative stress, intestinal histomorphology, and rectal microbial modulations weaned pigs. A total 80 piglets [(Landrace × Large White) Duroc] both sexes (a ratio gilts barrows;...

This study evaluated the effect of oil-in-water (o/w) emulsion supplementation in feed compared to a conventional oil and emulsifier combination on fat protein digestibility growth performance broiler chickens. The effects this macronutrient digestion kinetics were investigated through simulated vitro based gastrointestinal tract.2. A total 450 one-d-old Ross 308 chickens assigned one five dietary treatments consisting nine replicates 10 broilers each. included control diet containing...

Tannins have long been considered 'anti-nutritional' factors in monogastric nutrition, shown to reduce feed intake and palatability. However, recent studies revealed that compared with condensed tannins, hydrolysable tannins (HT) appear far less impact on growth performance, but may be inhibitory the total activity of caecal bacteria. This turn could microbial synthesis skatole indole hindgut entire male pigs (EM). Thus, objective this study was determine a group dietary HT carcass traits...

1. The potential of lecithin and lysolecithin to improve lipid digestion growth performance was investigated in three experiments: an vitro model that mimics the intestinal conditions chick, 2. a digestibility trial with chicks (5-7 days age), 3. until 21 age. In experiment 1, palm oil (PO), (PO+L), (PO+LY) were subjected hydrolysis applied Caco-2 monolayers assess absorption. rate triglycerides higher PO+LY (k = 11.76 × 103/min) than either PO 9.73 or PO+L 8.41 103/min), absorption...

Microbiome plasticity in chickens provides an attractive target for future potential therapeutic platforms. However, a better understanding of the chicken microbial ecology and how interventions such as xylanase addition can modulate this is needed. Interest essential additive livestock manipulating growth performance has been reported early 1980s. In paper, we describe new leads to array benefits broilers, not only by improving broiler nutrient digestibility, but also clearly gut health....

Oxidative reactions in premixes or final-compound feed pose considerable challenges to the poultry industry, both terms of rancidity reducing palatability and shelf life vivo oxidative stress negatively impacting animal performance. Whilst there has been broad awareness oxidation for many years, recognition impact on industry grown past twenty years. The appearance woody breast associated muscle meat myopathies led a rapid increase research output reactions. widely demonstrated damage...

Two experiments were carried out to determine the effect of increasing phytase levels on apparent total tract digestibility (ATTD) nutrients, P and Ca retention growth performance in weaned piglets fed corn or wheat based diets. Five treatments tested including a positive control (PC) meeting piglet nutrient requirements; negative (NC) formulated with reduction digestible (−1.4 g/kg −1.5 Exp. 1 2 respectively) (−1.5 both studies); NC supplemented Buttiauxella at 500, 1000 2000 units (FTU)/kg...

Fats and oils represent the most concentrated source of energy available to animal nutritionists form an expensive part diet. Thorough understanding lipid quality composition are required for efficient precise diet formulation. Therefore, 724 samples commercially fats were assessed fatty acid profile, oxidation status energetic value as per Wiseman equation, with consideration a correction factor K, which is based on presence diluting compounds moisture, impurities unsaponifiables.Energy...

Anti-nutritional compounds such as non-starch polysaccharides (NSP) are present in viscous cereals used feed for poultry. Therefore, exogenous carbohydrases commonly added to monogastric degrade these NSP. Our hypothesis is that xylanase not only improves laying hen performance and digestibility, but also induces a significant shift microbial composition within the intestinal tract thereby might exert prebiotic effect. In this context, better understanding on whether how chicken gut...

This study aimed to evaluate the effect of supplementing a combination lysolecithin, synthetic emulsifier, and monoglycerides (LEX) on growth performance, intestinal morphology, selected carcass traits in broilers fed low-energy diets without added oil. Three hundred one-day-old Arbor Acres (AA) (40.3 ± 3.3 g) were assigned two dietary treatments with six replicates 25 birds each control diet oil supplemented 0 250 g/t LEX for 30 days. Growth performance was measured recorded throughout...

This study aimed to evaluate the effect of supplementing different protease enzymes on growth performance, intestinal morphology, and selected carcass traits in broilers fed diets reduced 3.5% crude protein (CP) amino acids (AA). One thousand one-day-old Ross 308 (41 g) were assigned five dietary treatments with ten replicates 20 birds each: (PC) a positive control diet formulated meet acid requirements, (NC) negative reformulated provide lower CP AA compared PC, (PR1) NC supplemented...

The addition of xylanase to piglet diets is known improve performance and nutrient digestibility. present study aimed assess the impact new on growth performance, digestibility, gut function weaned piglets. A total 144 pigs, at 28 days (7.48 kg initial body weight, IBW), were assigned 36 pens 9 per treatment. Dietary treatments a basal complex control diet, diet supplemented with 45,000, 90,000 135,000 U/kg xylanase. Performance was measured 0, 14 35. At day 35, samples collected for...

Supplementation of feed enzymes such as xylanases has been shown to lower intestinal digesta viscosity and improve nutrient digestion thereby resulting in better gut health due the reduced availability undigested nutrients for growth harmful bacteria. Oligosaccharides produced by xylanase situ from dietary non-starch polysaccharides with potential prebiotic effects could modulate microbiome. This paper reports positive a new monocomponent improving performance modulating microbiota broilers....

Low crude protein (CP) diets can reduce nitrogen (N) excretion and costs by increasing N utilization efficiency. Exogenous proteases may further improve digestibility in low CP diets. This study first evaluated vitro the efficacy of a multi-protease on amino acid (AA) release from feedstuffs broiler feed. Later, effect feeding corn-soybean meal containing three levels (17, 19, 21 % CP) with supplementation top 0 or 2,400 U/kg chicken growth performance, total tract CP, ileal AA...
