Example text

This point, in fact, raises two questions. 1. Is it possible to measure the behaviour of a large number of birds at a low cost? 2. Is it worth doing from welfare and commercial points of view? Question 1 - Is it possible? Before selection programmes can be devised we need to record the behaviour of a large number of birds in a relatively short time, but most observations of this sort take a long time. g. social behaviour and, because of the inevitable variability of the stimulus conspecific, these observations must be repeated several times.

If they are given a choice of switching lights off or switching them on, they choose to have more light but, again, they tend to have their light during the normal daytime. We are now seeing if they will work in order to switch lights off, if they will work actively in order to have a dark period. After that we are going to see if they have any preferences for level of illumination. R. Tauson (Sweden) I would like to ask Dr. Petersen if he has any figures on ammonia concentration in the air, ppm, also if he has the lux measurement of the light intensity on the different tiers he showed us.

In answer to the question posed by the title, the environment certainly needs to be improved, but it is also likely to be worth improving the bird's adaptation at the same time. It 29 is possible, for example, to reduce fear-eliciting stimuli but not to suppress them. Thus, a selection programme to reduce fearfulness would probably produce good results whatever types of breeding conditions prevail in a few years time. , 1979.
