The Broiler Industry • Today, almost all of the poultry is raised in large operations • The term broiler refers to chickens which are about 7-8 weeks of age and are raised for meat. • Generally lighted 24 hours a day • Helps cut down on cannibalism • Process begins with the production of eggs that will be hatched into chicks. • Parents are selected from breeds that are large and muscular • Most are hybrids derived from mating of different breeds • usually mated through artificial insemination results in hybrid vigor
Egg Production • Eggs are expelled from the hens body and the embryo develops outside the mother’s body. • Eggs are encased in a hard shell and can weigh several ounces • Process begins with the release of the ovum (yolk) from the ovary • If the female has been mated, the ovum will be fertilized within the infundibulum. • The albumin or white of the egg is secreted by cells in the magnum. • Chalazae is formed, It is a ropelike substance which holds the yolk in place in the center of the egg.
Egg Production • Inner and outer shell membranes are formed in the isthmus • The shell is formed in the uterus • In 18-20 hours the shell is completed and moves to the vagina and out of the hens body. • Some facilities collect eggs with the use of a conveyor belt • The egg rolls out of the nest box and onto the belt • Eggs must be kept clean and free from contamination
Egg hatching • Eggs are stored at 70-80 degrees until being placed in the hatchery • within 48 hours after incubation begins the embryo has developed a circulatory system • Circulatory system sustains life by carrying nourishment from the yolk to the embryo • Eggs are turned at least two times per day • Turning eggs keeps the embryo from sticking to the inside of the shell • By the end of the first week, embryos are recognizable as chickens
