Uniformity

Grading according to body weight

One of the most important indicators for the quality of broiler breeder rearing is the uniformity of the flock. This is ensured by an optimal flock management: adequate and needs-based feeding, a simultaneous start of lay and as a result, a higher laying performance level of the entire flock. Grading broiler breeder flocks in different weight-based groups is a reliable method to achieve more uniformity in the flock and will result in a better overall performance.

With its patented technique, GRADY allows this labor-intensive process to be made more effective and efficient. In addition, with GRADY it is possible that birds get vaccinated as part of the grading process. This saves time, improves job quality and reduces the number of occasions the birds have to be handled.

Grading and recording

Computer-aided data collection

Each bird is weighed with a high-precision weighing cell and sorted into one of up to three groups. The classification of the groups is based on a sample, which is carried out at the beginning of the process with the device. GRADY is computer-controlled and operates with an intuitive touch screen. The data from the process can be transferred to a PC and then evaluated with Microsoft Excel or as a pdf. All the weights of the individual birds are recorded and the average weights and the CV values are automatically calculated.

Multi-functional

Combines grading with vaccination

With GRADY, grading is simplified and you are also able to combine it with the vaccination process. With the special patented cradle supporting the birds at the base of their wings, the breasts of these birds are better presented to the person vaccinating. This allows fast, safe and accurate vaccinations in the breast. Also, other forms of vaccine applications, e.g. above the eye or in the wing, are made easier with GRADY. Up to 6 positions for vaccinators (GRADY 4000) allow the supplying of different vaccines to the birds within one process.

Setup and performance

Effective automation

It only takes two people to setup GRADY. The machine is easy to clean and disinfect. It is therefore made entirely out of stainless steel and aluminum. 

The theoretical performance of GRADY 3000 ist more than 3,300 birds per hour. Practically, a performance objective of 2,000 birds per hour ist easily achievable and this includes setup and removal of the device and rounding up the birds. GRADY 4000 features a higher theoretical capacity of more than 4,000 birds per hour. Including setup, cleaning and packing, a performance objective higher than 3,000 birds per hour is achievable.

Through automation and the combined process of vaccinating and grading in one step, GRADY reduces the workload significantly. In line with a scientific investigation, a time-saving of up to 65 percent was measured.

Standard model

GRADY 3000

GRADY 3000 is the perfect choice if you need support for up to approximately 500,000 gradings per year on a farm. The machine can be easily transported between individual stables. It is foldable and fits through regular doors (>85cm) and can be stored space-saving.
