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 36 Egg Production Eggs are expelled from the hens body and the embryo develops outside the mothers 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. 37 Egg Production Inner and outer shell membranes are formed in the isthmus The shell is formed in the uterus In 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 38 Egg hatching Eggs are stored at 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 39 STRESSORS Cold Humidity Bacteria Viruses Protozoa Loud Noises Beak Trimming Parasites Poor Ventilation Mold & Mycotoxins NH 3 /H 2 S Heat Dust Vaccination Rough Handling Poor Sanitation Molting Weighing Pecking Order Feed Restriction Nutritional Deficiencies Poor Litter Quality Dirty Water Crowding 40
