- Abstract
Researches performed in this study aimed to study semen quality and breeding efficiency and other characters that in conjunction are shaping the fecundity of breeding cocks in ROSS 308 breeding cocks under the influence of some microclimatic factors (light intensity, birds density). Observations during the three trials (A - with analyze parameters sub-standard and litter made of chopped straws B - with analyze parameters above standard and litter made of rice hulls and C - with analyze parameters at the level recommended by the manufacturer of biological material and litter made of wood shavings) were performed during 3 control weeks (25, 35 and 45) during production period (19-64 weeks). The values obtained for sperm concentration were between 0.730 ±0.02 billion/ml, in week 45 - series C of trials and 1.044 ± 0.07 billion/ml in week 35 - series A of trials. Therefore stress due to microclimatic parameters stepping up manifests itself through slight decrease in the concentration but secures a consistency of its value on a longer period which would positively influence the effectiveness of breeding.
