Changing patterns of human resource use and food consumption have profoundly impacted the Earth's biosphere. Until now, no individual taxa been suggested as distinct characteristic new morphospecies representing this change. Here we show that domestic broiler chicken is one such potential marker. Human-directed changes in breeding, diet farming practices demonstrate at least a doubling body size from late medieval period to present domesticated chickens, an up fivefold increase mass since...

Work was undertaken to investigate the potential use of housefly (Musca domestica) larvae reared on broiler manure as a source nutrition for poultry production in United Kingdom. Nutritional analysis showed that have high (>45% dry wt.) protein content and favorable amino acid profile is rich key acids, such lysine methionine. A digestibility trial carried out determine apparent ileal coefficients (AIDC) true (TIDC) acids (AA) from insect larval meal (ILM) M. domestica fishmeal (FM)...

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...

There has been discussion regarding microbial phytase replacing inorganic phosphorus (P) supplementation in broiler diets. Therefore, an experiment was conducted to examine the effect of on diets low P. Ross 308 broilers (n = 288) were fed one 6 experimental 4 phases. The control diet had 16.20, 10.90, 9.40, and 6.10 g/kg P Starter, Grower 1, 2 Finisher phase respectively. remaining 10.50 Starter phase. Two graded reductions 5.10, 3.60, 0.60 or 2.00, 0.50, for respectively, plus 500 FTU...

Recently, nanotechnology has been widely adopted in many fields. The goal of this study was to evaluate the potential for amino acid coated nano minerals as a supplement broiler feed. Zinc selected model mineral test and supplementation zinc, both uncoated compared with organic inorganic commercial forms zinc. A total 48 pens (8 birds each) were assigned one following dietary treatments: Control, methionine-Zinc chelate (M-Zn), zinc oxide (Nano-ZnO), methionine (M-Nano-ZnO). All experimental...

There is little consensus as to the most appropriate methodology for measurement of gastrointestinal pH in chickens. An experiment was conducted establish optimum sampling method determination broiler digesta birds fed differing levels dietary calcium. Ross 308 broilers (n = 60) were 1 2 experimental diets, one containing 0.8% monocalcium phosphate and 2% limestone 0.4% 1% limestone. Four factors investigated determine measuring pH: removal from tract, prolonged air exposure, altering...

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...

Restriction in antimicrobial use broiler chicken production is driving the exploration of alternative feed additives that will support growth through promotion gastrointestinal health and development. The objective this study was to determine effects dietary inclusion laminarin on performance, expression nutrient transporters, markers inflammation intestinal integrity small intestine composition caecal microbiota chickens. Two-hundred-and-forty day-old male Ross 308 chicks (40.64 (3.43 SD)...

Abstract The British Standards Institution's Publicly Available Specification 440 (PAS 440) provides a Responsible Innovation Framework (RIF) that companies can use to continuously monitor the societal, environmental and health benefits risks of their innovations, as well relevant changes supply chain regulations. PAS is intended help achieve innovation in timely manner avoid any potential harm or unintended misuse new product, process service. Here, authors have applied RIF novel...

There is little consensus as to the capability of poultry utilize dietary phytate without supplemental phytase. Therefore, an experiment was conducted examine extent which endogenous phytase intestinal and cereal origin contributes degradation in birds aged 0 14 d posthatch. Ross 308 broilers (n = 720) were fed one 4 experimental diets with differing ingredient combinations approximate total levels 10 g/kg, activity analyzed at 460 U/kg, calcium (Ca) 11 nonphytate-phosphorus (P) g/kg....

The use of inert markers in broiler diets eliminates the need to quantitatively evaluate feed intake and excreta output determine diet digestibility, enables nutrient uptake at specific points along gastrointestinal tract be examined. Titanium dioxide (TiO2) is commonly used for this purpose measured using a UV-spectrophotometric assay. Two experiments were conducted observe whether an inductively coupled plasma optical emission spectrophotometer (ICP-OES) assay able replace UV-spectroscopy...

Koala populations in southeast Queensland are under threat from many factors, particularly habitat loss, dog attack, vehicle trauma and disease. Animals not killed these impacts often rescued taken into care for rehabilitation, eventual release back to the wild if deemed be healthy. This study investigated current rescue, rehabilitation data koalas admitted four major wildlife hospitals (Australia Zoo Wildlife Hospital (AZWH), Currumbin Sanctuary (CWH), Moggill (MKH) Royal Society Prevention...

In this study, we assessed uptake and potential efficacy of a novel, pH neutral form silicon supplement in vitro using broiler chickens as model species. bioavailability was significantly higher than other commercial supplements tested, all which claim available silica content. To confirm the new vivo, chick feeding trial reported blood that Bamboo-derived supplement. We dose response novel further study with increased related levels being detected tibia. found tibia foot ash residue...

This experiment was conducted to investigate the supplemental effect of rosemary leaf meal (RLM) on egg production and quality in Lohmann-Brown laying hens. For each treatment, six replicates were performed with four 24-week-old hens for a total 96 chickens. Dried present commercial hen ration at 0, 1.7, 3.5 5.2%, respectively. The interactions between dietary treatments, storage temperatures (4 °C, 21.5 °C), durations (7, 14, 21, 28, 35 days) examined factorial designs using fully...

Around 70% of total seed phosphorus is represented by phytate which must be hydrolysed to bioavailable in non-ruminant diets. The limited endogenous phytase activity animals make it common practice add an exogenous source most poultry and pig feeds. mature grain (MGPA) cereal seeds provides a route for the themselves contribute digestion, but MGPA varies considerably between species varieties current use negligible contributions. Currently, all phytases used feed supplementation transgenic...

Summary A study was conducted to evaluate a natural carbohydrate fraction Actigen™ (NCF), derived from mannanoligosaccharide, in feed on growth performance, intestinal morphology and goblet cell number area of male broilers'. Dietary treatments included: 1) control diet (antibiotic NCF free), 2) at 200 g/t, 3) 400 4) 800 g/t. Two hundred forty birds were placed into 12 replicate pens per treatment (5 birds/pen), sixty treatment. Body weight intake recorded weekly up day 42. At this time...

Measurements of total phytate phosphorus content diets may be deceptive as they do not indicate substrate availability for phytase; it that measurements susceptible to phytase effects are a more accurate measure (P) the bird. To verify this hypothesis, an experiment was conducted compare formulated contain either high or low phytate, supplemented with 0 500 FTU/kg phytase. Susceptible determined by exposing feed samples conditions mimicked average pH proximal gastrointestinal tract (pH 4.5)...
