Abstract Background This investigation assessed the effects of high dietary inclusion Spirulina ( Arthrospira platensis ) on broiler chicken growth performance, meat quality and nutritional attributes. For this, 120 male chicks were housed in 40 battery brooders (three birds per brooder). Initially, for 14 days, a standard corn soybean meal diet was administered. Subsequently, from days to 35, assigned one four treatments n = 10 treatment): (1) control (CTR); (2) with 15% (SP); (3) extruded...
Chlorella vulgaris is a microalga rich in proteins with potential applications food and feed industries. However, the presence of cellulose-containing cell wall, which major barrier to protein extraction, together fibroproteinaceous complexes, limits bioaccessibility nutritional bioactive peptides from C. biomass. Therefore, this study aimed evaluate effect different mechanical/physical pre-treatments (bead milling, extrusion, freeze-drying, heating, microwave sonication) combined or not...
Arthrospira platensis contains high protein content and quality, which makes it a promising feed source for livestock animals. However, this microalga presents recalcitrant peptidoglycan cell wall, its main proteins form protein-pigment complexes attached to the algal thylakoid membrane. The purpose of present study was evaluate effect mechanical/physical pretreatments (bead milling, extrusion, freeze-drying, heating, microwave sonication) combined with commercial enzymes (trypsin or...
Arthrospira platensis has emerged as a novel protein feed source since it contains high level and quality. However, this microalga presents recalcitrant cell wall its main proteins form protein-pigment complexes attached to the thylakoid membrane. The objective of present study was evaluate influence mechanical/physical pretreatments (bead milling, extrusion, freeze-drying, heating, microwave sonication) on A. solubility. Total content solubility were assessed by Bradford method SDS-PAGE...
The hypothesis that condensed tannins have higher inhibitory effect on ruminal biohydrogenation than hydrolyzable was tested. Condensed tannin extract from mimosa (CT) and chestnut (HT) or their mixture (MIX) were incorporated (10%) into oil supplemented diets fed to rumen fistulated sheep. Fatty acid dimethyl acetal composition of contents bacterial biomass determined. Selected bacteria analyzed by quantitative real time PCR. Lower (P < 0.05) volatile fatty acids concentrations observed...
Green macroalgae, e.g., Ulva lactuca, are valuable bioactive sources of nutrients; but algae recalcitrant cell walls, composed a complex cross-linked matrix polysaccharides, can compromise their utilization as feedstuffs for monogastric animals. This study aimed to evaluate the ability pre-selected Carbohydrate-Active enZymes (CAZymes) and sulfatases degrade U. lactuca walls release nutritive compounds. A databank 199 recombinant CAZymes was tested in vitro action towards wall...
Synthetic vitamin E is commonly used in aquafeeds to prevent oxidative stress fish and delay feed flesh oxidation during storage, but consumers' preferences tend towards natural antioxidant sources. The potential of vegetable antioxidants-rich coproducts, dried tomato (TO), carrot (CA) coriander (CO) was compared that synthetic included diets at either a regular (CTRL; 100 mg kg-1) or reinforced dose (VITE; 500 kg-1). Natural antioxidants were added 2% the CTRL. Mixes then extruded dried,...
O objetivo deste estudo foi avaliar a influência bioclimática da região de Carajás-PA na produção leite em rebanho especializado. Foram utilizadas 40 vacas raça Jersey lactação, com peso médio 280 kg, idade média 6 anos e no início do trabalho 290 dias lactação. A mensurada mensalmente por 3 consecutivos. temperatura ar, umidade relativa, pele, vaginal retal, bem como emissão calor termografia infravermelha foram mensuradas consecutivos após as ordenhas manhã tarde. Os dados utilizados pelo...
The brown seaweed Laminaria digitata, known for its prebiotic qualities, and alginate lyase supplementation, may improve the growth development of piglets during critical post-weaning phase. purpose this study was to ascertain effects 10 % L. digitata 0.01 on proteome metabolome longissimus lumborum muscle in weaned piglets. Findings suggest that enzyme supplement has a marginal effect compared diet alone when control. increased prevalence proteins related contraction structure (such as...
Chlorella vulgaris (CH) is usually considered a feed supplement in pig nutrition, and its use as an ingredient poorly studied. Among many interesting characteristics, this microalga has high protein levels can be putative alternative for soybean meal. Our aim was to study the effect of 5% CH incorporation diet, individually or combined with two carbohydrases, on meat quality traits nutritional value. Forty-four post-weaned male piglets housed, initial live weight 11.2 ± 0.46 kg, were...
Seaweeds, including the green Ulva lactuca, can potentially reduce competition between feed, food, and fuel. They also contribute to improved development of weaned piglets. However, their indigestible polysaccharides cell wall pose a challenge. This be addressed through carbohydrase supplementation, such as recombinant ulvan lyase. The objective our study was assess muscle metabolism piglets fed with 7% U. lactuca 0.01% lyase using an integrated transcriptomics (RNA-seq) proteomics (LC-MS)...
The impact of 15% dietary inclusion Spirulina ( Arthrospira platensis ) in broiler chickens was explored, focusing on blood cellular components, systemic metabolites and hepatic lipid mineral composition. From days 14 to 35 age, 120 were divided allocated into four treatments: a standard corn soybean meal-based diet (control), diet, extruded super-dosed with an enzyme blend (0.20% porcine pancreatin plus 0.01% lysozyme). haematological analysis revealed no significant deviations p &gt;...
This study evaluates the effect of prolonged feeding with a high inclusion level Spirulina, combined peptidases, on broiler chicken’s growth performance, digesta viscosity, carcass attributes and meat quality. The experiment involved 120 male broilers divided into 40 battery brooders, each housing 3 birds. Post 7-day acclimatisation corn soybean-based diet, birds were provided one four diets: soybean meal-based diet (CON), mix incorporating 15% Spirulina (SP), Spirulina-rich supplemented...
