The global warming is topical on a global level today. In a parallel line with it the number of scientific
researches which demonstrate the negative effect of high temperature over production performances,
health and well being of the animals is increasing. Although the hens are homeothermic and
keep constant body temperature, in comparison to the other home animals, they are more sensitive
towards the temperature changes of the environment and thus more liable to developing a thermal
stress. Consecutively the global warming, represents a direct threat to the poultry production. Having
in mind that annually in the world 1 trillion and 300 billion eggs are produced and that they are highly
nutritive food which the human nutrition does not have analog replacement, the finding of methods for
overcoming the thermal stress and keeping the production at a level that satisfies the public consumption
is of vital importance. Our aim is to make a correlation between the vitamin C as a f...ood supplement
and the productivity of laying hens in conditions of thermal stress. The research is carried out
in the poultry farm ‘Beli Most’ – Bitola, North Macedonia and 13200, thirteen-month-laying-hens of
Isa Brown type took part. The research lasted for 40 days and was conducted in two parts. In the first
part i.e. the first 20 days the daily laying at average daily temperature of 23.84 Celsius degrees was
followed. In the following twenty days the daily laying was followed again, but this time at an average
daily temperature of 25.54 Celsius degrees and vitamin C as a food supplement. The vitamin C was
added in the amount of one kilogram to one ton. In the first part of the research the average number of
daily laid eggs was 11847 or in total 236940 eggs for all 20 days. The maximum number of daily laid
eggs was 12660, and the minimum was 11250. In the second part, the average number of daily laid
eggs was 11800 or in totals 236000 eggs for all 20 days. The maximum number of daily laid eggs was
13200, and the minimum was 10140. From the received results it can concluded that the increase of
ambience temperature for 1.7 Celsius degrees even with the additional vitamin C the production went
down for 40 eggs daily. In any case that reduction is insignificant. The absence of significant difference
between the productive performances in the first and the second part, the most probably is due
to the protective influence of the vitamin C.
