When we talk about the rearing phase of broiler breeder pullets, we look for help in broiler chickens’ starter manuals. The environmental conditions are essential, but the feeding management will be better if we think they are broiler breeder pullets and not chickens.

For the pullets’ management in this phase, our objective is not to obtain an excess on early bodyweight with voracious animals and great ease to gain weight because of its improved feed conversion ratio. Even an excessive yield would transform into a greater breast development. Therefore, the objective is to have uniform pullets without exceeding the recommended bodyweights. This allows weekly feed increments that supply the nutritional needs in each stage of the rearing without causing excessive weight gains.

Temperature control

Once the pullets arrive at the farm, the unloading process must be done quickly to avoid that trucks stay outdoors because it will cause loss of temperature and stress in the pullets.

To get optimum temperatures, it is necessary to pre-heat the house between 21 to 48 hours before pullets arrive. However, it depends on the season of the year

A relative humidity ≤ of 30% reduces the thermal sensation, and then the pullets feel cold. Under these conditions, a good practice is to increase the house temperature between 0.5 to 1ºC. If there is a high relative humidity (≥50%), the temperature must be decreased amid 0.5 to 1ºC. The effective house temperature together with pullets behavior will help us adjust the ideal temperature.

 

Ventilation

The ventilation must be turned off before the pullets’ placement to avoid unnecessary heat loss. Sometimes, it is preferable to pre-heat the house without litter extended on the floor. Once the floor reaches 28 degrees Celsius, the litter can be extended most uniformly.

 

The pullets from grandparent flocks with less than 30 weeks of age have 1 or 2 fewer temperature degrees during the first 7 days of age than those from older flocks under the same environmental conditions. At placement, these small pullets can require temperatures of
