The Effects of Black Mulberry (Morus nigra L.) Leaf Powder on Performance, Egg Quality, Egg Antioxidant Capacity, and Yolk Cholesterol Levels in Laying Hens

Abstract

Different antioxidant substance are supplemented to prevent oxidative stress and improve egg quality in poultry nutrition. It is known that synthetic antioxidants negatively affect human health. For this reason, natural antioxidants are often investigated. In this study, the possibilities of using different levels of black mulberry (Morus nigra L.) leaf powder (BML) in laying hens were revealed. For this purpose, 3 groups were formed, 24 in each group, and a total of 72 hens (35 weeks-old, Brown Nick) were distributed to individual cages. The control group (BML-0) was fed with a basal diet. Experimental groups were fed with the supplementation of 0.3 and 0.6 g/kg BML to the basal diet, respectively. Performance, egg quality characteristics, egg yolk TBARS, DPPH, and cholesterol levels were evaluated in the trial, which lasted for a total of 8 weeks, one week of which was the acclimatization period. There was no statistically significant difference between the groups regarding performance, egg quality characteristics, and DPPH reducing % in egg yolk (P>0.05). Egg yolk TBARS and cholesterol levels were significantly affected from supplemented-BML diet (P<0.05). It was determined that the cholesterol level of egg yolk decreased linearly with the addition of BML (P<0.05). It was determined that of the BML delayed lipid oxidation due to the decrease in TBARS value in the yolk. As a result, it is seen that black mulberry leaves can be used in obtaining low-cholesterol eggs and delaying lipid oxidation without adversely affecting performance parameters in laying hens. It is thought that it will be useful to reveal the effects of black mulberry leaf on different parameters in future studies. Keywords: Antioxidant, black mulberry, egg quality, cholesterol, TBARS.
