It is common to observe that due to these deficiencies in infrastructure many lots lose or do not maintain an acceptable uniformity in the rearing. The farm staff must have the correct infrastructure to facilitate the management and achieve the objectives of the companies.
The density of birds in rearing and production should always be a function of the infrastructure of the facilities. Densities of up to 10 females / m2 and up to 4 males / m2 are acceptable in rearing. In production, up to 6.0-6.6 females / m2 can be handled very well. Everything depends on the infrastructure in feeders, drinking fountains, ventilation and other important points. This article describes several important aspects in rearing (between 0 and 25 weeks of age) to achieve success in production.
1.- Enough feeder space
This means progressively increasing the feeder space in the breeding as the age of the birds advances. When dish feeders are used, a criterion similar to those in figure 1 should be applied. However, with dish feeders there may be some preference to feed on a daily basis if the amount of food allows it.
It is important to have enough food in the system so that all dishes have a reasonable amount and that the time of consumption is> 1h if possible.
The consumption time should be> 1h
2.- Fast food distribution
Chain speed: 120 feet / minute = 36 m / minute
Distribution throughout the channel in less than 3 minutes
In case of dish feeders, once the tube has been loaded with food, the availability of it is immediate in all areas of the house.
3.-Use chute for chickens if using chain feeders for feeding
The chute for chickens used during breeding, unlike the production chute (see Figure 2), allows more easily distribute the food over the entire length of the carcass while maintaining a good height of feed on the chain.
On the contrary, the use of production gutter in the aging period – which interests us in this article – complicates the distribution of food and negatively affects uniformity.
4.-Good distribution of the birds over the entire surface of the house before starting the distribution of food
The good distribution of the birds guarantees that they all consume food almost at the same time. Feeding with low light intensity or feeding using a light signal helps to obtain this objective.
5.-Sufficient water flow in the nipples
After 4 weeks of age, the water flow potential should be 50-60 cc / minute per pacifier feeder.
Approximately 4-5 hours after finishing the food, it should be possible to feel a malleable craw in all the birds.
6.-Good food uniformity
Presentation of the food with good uniformity of the crumble or coarse meal and with little segregation of the food particles.
7.-Sufficient light intensity (5-7 lux)
There must be at least 2 lines of lamps to achieve a uniform light intensity and be able to do all the work in the sheds without having to constantly manipulate the voltage regulator (dimmer).
This way we can control that the thickness of the bed and the height of the gutters or dishes on the bed are kept uniform. An excessive height of the plates or of the gutters harms the uniformity preventing the smaller birds to reach the food.
8.-Consistency in the use of equipment between the breeding and production facilities
The lack of consistency in the equipment used in breeding and production is often ignored and can induce many problems in production.
Promote the activity of the birds in preparation for production with grid floor. It is necessary to train the birds during breeding so that they have sufficient mobility when entering production. They must learn to jump to a higher level, the grid floor “slats” in production where water, nests and drinking troughs are commonly found.
Higher activity is observed with gutters than with dish feeders. The feeders of food dishes are filled at the same time, and therefore the birds are calmer.
Meanwhile, with breeding gutters, birds constantly jump over them to move laterally inside the house. thus they are accustomed to a greater mobility in comparison to the pollonas bred with dish feeders.
