With the transformation of poultry manure, by means of different treatments, such as drying, an alternative is generated to give value to an abundant waste in our laying hen facilities and also mitigate the negative environmental impact that is produced when poultry manure is not processed.
With this article, Zucami’s technical team pretends to present TIPS that help our clients to learn about a plus value subproduct such as poultry manure in our laying hen farms.
Poultry manure, organic waste from farms.
Poultry manure is a mixture of chicken feces and urine, to which are added feathers, cells of the digestive tract mucosa, the non-digestible portion of feed and several mineral salts.
Layer manure and broiler manure are two different products:
Quantity and quality of poultry manure.
Knowing the quantity and composition of poultry manure and litter produced with different poultry production practices is essential for efficient and environmentally friendly management.
There are several factors that influence the quantity and quality of the manure, such as the age of the bird, the production and feeding system of the hens, feed consumption and composition, the amount of feathers, environmental factors such as temperature and ventilation, etc.
As a reference, it has been proved according to different studies that on average, birds produce 120-140gr of feces per day, which contain 75% of water.
What is poultry manure used for?.
The most common and advisable management of poultry manure is to use it as an organic fertilizer, contributing to increase agricultural production by improving crop productivity.
At the same time, it prevents the need to increase the agricultural area, conserving the soil and avoiding its degradation.
Knowing the effect this waste has on the environment makes it possible to adopt measures to increase sustainable productivity in poultry farming and, at the same time, to guarantee the health of producers, consumers and the environment.
Poultry manure management.
Fresh handling based on temporary piles can entail a number of problems (high costs of transport to the field, leachates, emissions, bad odors, difficulty of application in the field…).
To minimize these problems, two possible alternatives for handling prior to application, drying and composting, are proposed..
Composting is an aerobic fermentation, that is to say, in the presence of oxygen, of fresh organic matter of animal or vegetable origin, which is decomposed giving rise to a stabilized final product called compost.
The humidity rate, the dimensions of the piles, the space occupied by this waste, the management costs and labor costs make the drying of poultry manure the most cost-effective and efficient way to treat this product.
DRYING OF THE POULTRY MANURE:
The process of drying poultry manure seeks to achieve a more easily manageable product, improving its subsequent storage and agricultural valorization, also reducing the possibilities of contamination, as well as the emission of odors and the proliferation of insects in comparison with fresh handling.
