Background

The compositions of animal wastes is a complex issue, with the composition dependent on the class of animal, diet, digestibility of food, bedding, and stage of growth, among other factors.

Poultry litter is a mixture of poultry manure and the litter base, which can be straw, wood shavings, paper, or other biodegradable material.

The relative amount and type of manure produced will depend on the livestock class. For example, broilers produce about 0.036 kg/bird/day at 70% dry matter. Of this, about 70% by dry weight is manure, and the remainder is the litter base.

Analysis of Poultry Litter at Celignis

Celignis Analytical can determine the following properties of Poultry Litter samples:

If you would like us to analyse your Poultry Litter samples then please select the appropriate analysis packages from our list.

Cellulose Content of Poultry Litter

The cellulose content of the poultry litter will depend on the compositions of both the manure and the litter base and on the relative mass proportions that each of these contribute to the total litter mass. Typically, the base has a higher cellulose content than the manure, meaning that an increased base:manure mass ratio will lead to a higher cellulose content.

Hemicellulose Content of Poultry Litter

As with cellulose, the hemicellulose content of the poultry litter will depend on the compositions of both the manure and the litter base and on the relative mass proportions that each of these contribute to the total litter mass.

Lignin Content of Poultry Litter

The lignin content of the poultry litter will depend on the compositions of both the manure and the litter base and on the relative mass proportions that each of these contribute to the total litter mass.

Starch Content of Poultry Litter

The starch content of poultry litter will vary according to their diet.

Uronic Acid Content of Poultry Litter

Uronic acids are present in many of the feedstocks that are used to generate the bedding for poultry litter (e.g. straw, wood shavings), however we are not aware of any studies to date on the total uronic acid content of poultry litter.

Enzymatic Hydrolysis of Poultry Litter

We can undertake tests involving the enzymatic hydrolysis of Poultry Litter. In these experiments we can either use a commercial enzyme mix or you can supply your own enzymes.

We also offer analysis packages that compare the enzymatic hydrolysis of a pre-treated sample with that of the native original material.

Ash Content of Poultry Litter

As with other animal wastes, poultry manure can have a high ash content. However, the litter base typically has a lower ash content. Hence, an increased base:manure mass ratio will favour a lower total ash content in the poultry litter.

Heating (Calorific) Value of Poultry Litter

Unlike many other animal wastes, such as cattle and pig manures, poultry litter can have a relatively low moisture content (typically between 20 and 50%, depending on husbandry practices). Because of this, in recent years there has been increasing interest regarding the combustion of this resource.

Bulk Density of Poultry Litter

At Celignis we can determine the bulk density of biomass samples, including Poultry Litter, according to ISO standard 17828 (2015). This method requires the biomass to be in an appropriate form (chips or powder) for density determination.

Basic Density of Poultry Litter

At Celignis we can determine the basic density of some suitable biomass samples. The method requires the biomass to be in an appropriate form (chips) for density determination.
