The research conducted on this paper has had as main objective a study on the reproduction efficiency of ROSS 308 male line, under the influence of several microclimate factors such as the light intensity and the density of the flock, as well as other factors, which, if corroborated, would determine the fecundity capacity of the roosters. Three experiments have been constructed (A - with analyzed parameters under the standard and using bedding made of chopped straws, B - with parameters that have been raised over the standard limits and using rice hulls as bedding, and C - with parameters at the producer's recommended level, and bedding made of wood shavings). The observations have been made and the records have been taken during the production cycle (week 19 - week 64), over a period of 3 weeks (25, 35 and 45 weeks of age), for two consecutive years, on a group comprising 25 roosters and 250 hens, for each experimental series. The results show the highest fertility rate for the experimental series C, over all the control weeks (50 %, 95, 1 %, 93, and 4 % respectively). The differences, although not statistically significant, can turn the conditions of experimental series C very popular, making the wood shavings classic bedding a favorite, along with several technologically standard microclimate parameters. Overall, the fertility would register higher values (with 3-5 %), for which the economic efficiency would be making a difference (although not from a scientific point of view).
