Abstract Soybean meal (SBM), one of the main protein sources in turkey production is becoming expensive. Shrimp waste (SWM), a by‑product shrimp industry good prospect as cheaper alternative. It was hypothesised that Nigerian indigenous turkeys (NIT) should be able to digest and utilise SWM better than British United Turkeys (BUT) because their hardy nature. A 56‑day study carried out determine...

in order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, ross 308 strain. poultry by-product meal was prepared from two slaughter house in alborz province. samples were sent to laboratory for determination of chemical analysis. the birds received commercial broiler starter...

The inclusion of untreated rye or barley in poultry diets as a major ingredient causes growth depression. This is due to the high level of pentosans in rye (Antoniou and Marqurdt 1981) and the b-glucan content in barley (Gohl et al. 1977). It has been reported that some wheat cultivars grown in the eastern part of Australia show an unexpectedly low apparent metabolisable energy (AME) (~13 MJ/kg...

Three trials were conducted to determine the available energy of different wheat screening varieties collected from different locations of Khorasan in Iran. In experiment 1, chemical composition and the nitrogen corrected true metabolisable energy (TMEn) were evaluated. A precision-fed rooster assay was used, in which, each wheat screening sample was tube fed to adult roosters, and the excreta ...

Using ileal digestible amino acids in feed optimising will intensify feed protein utilizing and decrease nitrogen excretion to the environment. The study determined the apparent ileal digestibility (AID) coefficients of amino acids in barley, wheat, oats, triticale, maize, and dehulled oats in the diets of 180 Ross broiler chickens (aged 24–35 days). The birds were fed semi-purified diets that ...

Knowledge about metabolisable energy (ME) intake is crucial for various experimental settings in rodent studies. ME considers faecal and renal energy losses. In particular, faecal energy excretion can vary considerably between differentially composed diets. Thus determination of faecal energy losses, i.e. apparent energy digestibility, is the most important experimental approach to determine ME...
