Effects of Addition of Some Plant Extracts to Free-Raised Egg Chicken Feeds on Egg Quality Parameters



Phytase Enzyme, Red Pepper, Propolis Extract, Egg Quality, Free Range


It was determined that adding Phytase enzyme with 16 hours of illumination daily increased egg yield, feed consumption and egg weight significantly (P<0.01). Egg weight, egg white and yolk weights, egg shell weight and breaking resistance increased. and its effect on egg quality criteria was positive. Addition of 0.75% red pepper to the ration showed higher redness values of egg yolks (P<0.001). The difference was found to be statistically significant. In this study, it was revealed that the addition of red pepper had a positive effect on the yolk color of free-raised laying hens. An in vivo experiment was conducted to determine the effect of adding Dried Capers (Capparis spinosa) leaf to the diet. Powder (DCL) four groups of commercial chickens (ATAK-S) 0, 5, 10 and 15 g on egg production and egg quality of laying hens at the beginning of the laying period. They were fed diets containing DCL/kg. The results showed that dietary DCL had no effect on feed intake, egg mass (EM) and egg production parameters (P>0.05). As a result of the study, the addition of feed propolis extract did not have a significant effect on performance values among the experimental groups. The yolk of the eggs in the groups coated with propolis extract was found to be lighter. On the other hand, the effect of propolis coating on the specific gravity values of the eggs was found to be significant. In addition, a decrease was observed in TMA values. In the electron microscope picture examination, it was observed that the propolis coating created a closing/occlusive effect on the eggs. As a result, when propolis application was added to the feed of chickens in the chicken pasture, there was no difference in terms of the performance parameters examined. However, it has been observed that coating the eggs with the extract has an effect on increasing the shelf life. No statistically significant difference was observed in the performance results during the experiment with the addition of alfalfa juice. However, it was observed that egg mass values tended to increase as age and yield increased. No statistical difference was observed in the first 4 weeks in the examined external quality parameters. 25-28. At the age of week, the effect of interaction was found to be significant in egg weight, shell break resistance and shell ratio. It was determined that the difference observed in egg weight and shell ratio was due to the pasture effect. It was observed that the statistical difference observed in the shell cracking resistance was caused by the addition of alfalfa juice and was positively affected. In the last 4 weeks, the effect of the interaction was found to be statistically significant only on the shell weight and shell thickness parameters
