e-newsRockin’ t the EuroTier exhibition in Germany last November, we were pleased to show for the first time the new ROCK Control System. At the IPPE in Atlanta on January 31- February 2 we will once again Rock On! Now working for close to a year on testing, but even more recently expanding with additional units due to the great results, ROCK is here to stay. Besides the new front panel design, ROCK is an innovation in control technology built on a platform designed to grow in the future. o

What makes it unique is that ROCK senses the temperature of the air as it returns to the fan. is temperature represents that of the egg

mass. e setter temperature can then be set to maintain a constant differential so that the egg temperatures

can remain stable. Rather than judge and determine set points by reading a

few eggs in a specific . . l o c a t i o n ,

ROCK gets i t s

feedback from all the eggs in the setter, or chicks in the hatcher. It builds on uniformity that is central to the design of the Avida setter with even airflow passing through one trolley of eggs from fan to wall. It is possible to use 20-step stage programs for those that want to have that feature. o

e way the temperatures are kept more consistent is also through a variable speed sensor in the fan that automatically adjusts the fan movement, keeping the temperature, humidity, and CO2 levels under control. e modulating cooling valves regulate with the correct flow of water to precisely manage cooling rather than overdo do it by being 100% open or closed. ese new valves are self-adjusting using PID control to ensure the cooling arrives smoothly for the right temperature. is will reduce energy, water consumption, and give a superior quality chick. e controls themselves are all mounted in the center panel making it more accessible to maintain. All the PLC's are built into the touch screen making it a more compact package.

ere are already several new hatcheries committed to the ROCK that will be installed in 2017. Come visit us

e process of incubation takes place like a jigsaw puzzle made up of several elements: temperature, turning, humidity and airflow. If any of the components are missing or do not take place correctly, the product may not meet the desired expectations. Humidity loss is one of the parameters that should be monitored in order to make adjustments in the incubation process.o

Obtaining adequate humidity levels in the environment in which eggs are incubated causes embryos to lose water from their interior to the

exterior through constant evaporation. rough this process the ideally sized air cell is able to be

formed to facilitate the embryo's pipping of the internal membrane between days 19-20.

is is the way the transition from chorioallantoic to lung breathing takes

place. Additionally a better water and mineral balance is created, contributing to p r o p e r e m b r y o n i c

development. In order for this to take place, the ideal humidity loss

should be between 11% and 13% on day 18 of incubation.

o

Each egg has different characteristics such as size, thickness, the amount of pores and shell conductance.

For example, in older flocks the conductance and size of the egg are greater; therefore they should be incubated with higher

humidity. It should be remembered that thousands of eggs are handled so they should be grouped in a way that their characteristics

be as similar as possible; by flock, age and days in storage. With that, there will be a more uniform environment inside the machine.o

How should humidity loss be measured? Trays from different zones of the machine should be weighed before being set, and again during the transfer. en the weight loss percentage is calculated. At any rate, it's important to check:o

• e pipping line when the chicks are removed from the basket• Presence of navels with strings• Presence of red hocks or beaks• Chicks that are sticky with albumin or shells stuck to the downo

ese observations are evidence if the weight loss is adequate or not, and if the humidity in the hatcher is being handled correctly. is way, corrective measures can be taken. When there is insufficient weight loss, the hatch is difficult; the chick requires more energy expenditure

to be able to hatch, causing a weaker chick to be born. On the other hand, an egg that has the ideal weight loss will experience an easier hatch and will spend less time saving energy. Weight loss is not only influenced by moisture in the air, but also by temperature. As the temperature increases, caused by embryonic development and growth, evaporation increases through the shell. Also, the movement of water from the albumin to the sub-embryonic cavity is expanded. o

O n o n e h a n d , m u l t i - s t a g e machines keep the temperature and h u m i d i t y p a r a m e t e r s constant during the incubation process because they have 6 sets in the machine with different embryonic states. On the other hand, the single-stage machines adjust to embryonic requirements, reducing the humidity as seen in the Graph below. Moreover, it doesn't have humidity spray, but rather the embryo itself produces the required humidity and this is reduced through damper control to create greater uniformity. o

A well-sealed single stage machine helps the humidity increase quicker than CO2, which is the reason why the damper can be controlled by humidity. o

When there are eggs from old breeders the damper will open earlier and when a young flock with low fertility is set, the damper will open later, adapting itself to the characteristics of the flock that is in the setter.

To get good weight loss, classification and order must be maintained when handling the eggs in the cool room, checking chick quality, measuring weight loss and adjusting it according to the results. Also, it's important to maintain the machines in good shape in order to have uniformity and balance within the cabinet. Adequate weight loss offers benefits for embryonic development and in the hatching process, which results in energy savings during the hatch, and in obtaining a chick with excellent potential.

Pussalla Grows its Hatchery in Harmonye poultry industry continues to expand as the demand for animal protein grows. Pussalla Meat Producers (PVT) Ltd, the leading poultry producer in Sri Lanka, has just completed its next phase of expansion. e new Avida setters with 18 trolleys and Avida C192 hatchers are shown above with the Pussalla installation team, along with Simon Witherden, the ChickMaster installation engineer. Pussalla first installed Avida incubators a few years ago. ey have benefited from the uniform airflow and consistent hatch results with superior chick quality. is new expansion gives Pussalla a production of 25 million chicks per year. o

e hatchery also benefits from a CC3 climate control system to manage the hatchery environment. In a country with high humidity, the CC3 efficiently dehumidifies the air using free energy resulting in controlled moisture loss during the incubation process and excellent baby chicks. We are pleased to be associated with Pussalla and to be their preferred supplier of single stage incubation and ventilation systems.

e power cords connect to the fan assembly. Aer each hatch, the fan assembly can be disconnected by unplugging the power cord. e power cord comes with a cap that is to be used prior to cleaning to avoid water entering the plug that could lead to a burning out of the power connection. Maintaining the plugs is important to keep continual power to the fans that supply air to the chicks as they hatch. It is good to check these cords aer each hatch and also have a few in stock in case a replacement is required.
