![]() ![]() It can be concluded that betaine supplementation up to 0.21% to low methionine diet only had little effect in improving the quality traits of quail eggs.īetaine supplementation lowers plasma homocysteine in healthy men and womenĮlevated levels of plasma total homocysteine are associated with a higher risk of cardiovascular disease. However, supplementation of betaine did not affect protein content, yolk, albumen, and eggshell percentage. ![]() Increasing dietary levels of betaine increased the fat content of the egg with the linear regression of y = 11.0949 + 4.1914x (R2 = 0.18). The data were subjected to analysis of variance, and when the treatment indicated significant effect, it was continued to orthogonal polynomial test to determine the optimum level of betaine. The experimental diets were applied for 8 weeks and the egg quality traits were measured at the age of 16 and 20 weeks. The four dietary treatments were the low methionine diet (0.3% methionine) without betaine supplementation and the low methionine diet supplemented with 0.07, 0.14, and 0.21% betaine. The experiment was assigned in a completely randomized design. A total of 340 laying quails (Coturnix coturnix japonica) was divided into 4 dietary treatments with 5 replicates of 17 quails each. This experiment investigated the effect of betaine supplementation to low methionine diet on egg quality of quails. Egg quality of quails fed low methionine diet supplemented with betaine ![]()
