Sažetak
The research was conducted at the pheasant farm Božur in Satnica Đakovačka. Pheasants were kept in a closed building with the possibility of an outlet. For the purposes of the research, 120 common pheasant eggs, with brown and green shells, were sampled. Females laid eggs in early March, and egg sampling for analysis was carried out at the end of March and the beginning of May. During the first egg sampling in March, the pheasants were in the 5th week of laying, and when the eggs were sampled in May, they were in the 10th week of laying. The aim of the work was to assess the influence of the laying period on the quality of common pheasants’ (Phasianus colchicus) breeding eggs from controlled breeding, as well as to determine the acids content fatty and cholesterol in egg yolks. Pheasants were fed a feed mixture balanced to 17.30% protein. Feeding and watering was ad libitum. For the purpose of research, various recognized scientific methods were used to determine the quality of eggs, the fatty acids content and cholesterol in egg yolks. The research found that the laying period affects egg weight, egg surface, shell mass, albumen weight, and weight, height and pH of yolk (P<0.05). The fatty acids content was uniform in both periods of analysis (March – May), with the fact that the values of myristic, palmitic and ΣSFA were significantly higher in eggs sampled in May compared to March, while the content of linoleic and total n-6 PUFA in that period was significantly lower (P<0.05). The laying period had no effect on other analyzed indicators (P>0.05). According to the research results, it can be concluded that the quality of breeding eggs of common pheasants from controlled breeding changes with regard to the laying period (March 5th week of laying and May 10th week of laying).
