Natural Substances Supplement in Laying Hen Diet
Main Article Content
Abstract
Nutritionists now recognize that laying hen eggs contain essential nutrients for the human body to grow. In particular, laying hen eggs are considered the best food source of high quality protein.Because it has all the essential amino acids that the body needs, one egg contains 7 grams of protein per egg, amino acids, lecithin, vitamin A, vitamin B1, vitamin B2, vitamin D, calcium, iron and 75 calories per egg.The composition of one chicken egg consists of 3 main parts: egg shell, egg white, and egg yolk, with proportions equal to 11, 62, and 27 percent, respectively.The color of the yolk affects the palatability of the food. Therefore, it affects the satisfaction and acceptance of consumers.The egg production industry often adds synthetic colorants to increase the intensity of the egg yolk color.There is also the addition of natural pigments, such as the use of ground dried mulberry leaves in the feed of laying hens at a level of 3.0-20 percent, giving an egg yolk color value of 10.84.The use of crude mulberry leaf extract in laying hens' feed at a level of 1.0-1.2 percent gave an egg yolk color value of 7.01-10.50. The use of green bell peppers in laying hens' feed at a level of 225 ppm gave an egg yolk color value of 8.1.Using red chili in laying hens' feed at a level of 0.3 ppm gave an egg yolk color value of 10.2. Using Butea monosperma (Lam.) flower powder in laying hens' feed at a level of 1.00 percent gave an egg yolk color value of 6.53, and using hemp seeds in laying hens' food at a level of 5 percent gave an egg yolk color value of 6.20. In the yolk of laying hen eggs, there is lutein equal to 0.3-0.5 milligram per egg.The use of dried marigold flowers and marigold extract at a level of 40 milligram per kilogram of feed of laying hens gave lutein equal to 3 and 4 miligram per 100 g of egg yolk weight.It was also found that the use of hemp seeds and hemp oil in the laying hens' diet at a level of 20 percent resulted in egg yolks containing 144.6 and 250.6 milligrams of omega-3 fatty acids.Therefore, the use of natural supplements in the feed of laying hens, it is a way to produce laying hen eggs that have properties to promote health and reduce the risk of various diseases. Therefore, laying hen eggs can be considered a food that promotes good health.
