Egg size decreased slightly. The equation for calculating cooking yield is: Yield (%) = 100 x (Wch /Wcr) The cooked sample窶冱 raw weight (Wcr) is recorded before cooking. yield performance, laying behavioural traits and egg quality. HOW TO... 02 Each egg yolk contains about 1.6 grams of saturated fat. The fat in the yolk is so finely emulsified that it is digested easily, If you consume a 2,000-calorie diet, this is 7 to 11 percent of your recommended saturated fat for the day. Of this weight, the shell constitutes 11 percent; the white, 58 percent; and the yolk, 31 percent. The percentage of albumen yield decreased with increasing amounts of yeast fermentation product, and the percentage of yolk yield increased with increasing amounts of yeast fermentation product.

For many micronutrients, the egg content responds rapidly to dietary changes and transfer efficiency, from feed to egg, depends on the micronutrient. (1972a) examined egg changes of large turkey strains over a seven month lay­ ing period. The yolk makes up about 33% of the liquid weight of the egg; it contains about 60 kilocalories (250 kJ), three times the energy content of the egg white, mostly due to its fat content. Published by Elsevier Inc. Basically, total egg and yolk weight increased; proportion of shell and albumen de­ diet. The contents of the yolk sac are high in fat and protein but very low in carbohydrate, which could lead to ketosis with prolonged fasting.
