The Use of Organic Feed to Force the Color of the Yolk in Laying Hens

Abstract

The objective of this research is to evaluate the effectiveness of different food-production plants in enhancing egg yolk color and to compare the color quality outcomes from these plants. Specifically, the study focuses on the impact of banana leaves and water hyacinths when incorporated into the diet of laying hens.

The experimental process of this research involved a controlled feeding trial with 20 egg breeders divided into two groups, each consisting of 10 chickens. Over a six-week period, one group was fed 500 grams of banana leaves mixed into their daily feed, while the second group received the same amount of water hyacinths.

The results of this study reveal that incorporating banana leaves and water hyacinths into the diet of laying hens significantly enhances the color intensity of egg yolks. Specifically, hens fed with banana leaves achieved a yolk color score of 9.25, with a V value of 86.4%, an H value of 42.6, and a C value of 0.0. In comparison, hens fed with water hyacinths had a yolk color score of 7.26, with a V value of 75.2%, an H value of 46.4, and a C value of 0.0. The statistical analysis confirmed that the differences in yolk color between the two groups were significant (P<0.05). These findings indicate that both banana leaves and water hyacinths can enhance the yolk color, making it more intense and visually appealing. However, banana leaves proved to be more effective in achieving a higher color score. Importantly, the use of these natural feed additives did not negatively impact the overall quality of the eggs, suggesting their potential as viable options for improving egg yolk color in poultry nutrition.

This study demonstrates that incorporating banana leaves and water hyacinths into the diet of laying hens can significantly enhance the color intensity of egg yolks. Among the two plants tested, banana leaves proved to be more effective, resulting in a higher yolk color score and more intense coloration. The use of these natural feed additives did not adversely affect the overall quality of the eggs, making them viable options for improving yolk color in commercial egg production. These findings have practical implications for the poultry industry, offering a natural and cost-effective method to enhance the visual appeal of eggs, which can potentially increase their market value and consumer preference.
