 Project abstract:
The laying hens husbandry and exploitation, using conventional cage batteries will be forbidded in the near future, despite the fact that this technology is still applied in more than 70% of the laying hens flocks across the world.
Since the very beginning of 80s, certain so called alternative rearing systems have been designed and applied, in order to provide better comfort conditions to the fowl used for eggs or meat production.
These new technological concepts were not sufficiently tested within production conditions, although they fulfill most of the birds welfare requirements. Therefore, it is not fully known how they influence the well being or dicomfort status of the hens.
This project has as mai goal to study the morpho-productive, physiologic, anatomo-histologic and behavioral adaptability of the laying hens at those conditons provided by certain different alternative rearing system, either with vertical (improved cage batteries) or horizontal (permanent litter, with acces to an outer paddock) disposition.
Our study will focus on the dynamics of the fowl productive capacity, on their health status and on the main blood parameters, as well as on the eventually behavioral alterations, as responses to a new life habitat. In order to accomplish these, two laying hens hybrids will be tested, as they will be raised in three versions of alternaive systems (improved cages, opened cages and halls providing acces toward external paddocks), versions which provide higher freedom of movement, access to certain facilities (nests, resting poles, sand baths etc.), the posibility to exteriorise certain natural instinct and, of course, full acces to the natural living environment.
