Trainers’ Manual – Unit 6– Commercial Egg Production There are several choices that can be made about management and housing of laying hens. They can be kept in group () battery cages; this has a high capital cost unless the cages are constructed from . Results of the latest two tests were analyzed to study the potential benefit of molting compared to single cycle management in terms of annual egg production and egg income over pullet and feed cost. A non-fasting molt was induced at 69 weeks of age, with target weight reduction by 25% in the 38th NC test and 20% in the 39th NC test.

This study was aimed to evaluate the effect of force molting programs on egg production and quality of laying hens. Total of white Bovines laying hens at 72 weeks of age were divided into four. At the end of forced molting, body weight of the hen were decreased (P). Egg production of the hens from groups which did not subject to force Author: N. Prakobsaeng, W. Polviset, K. Wilachai, S.

Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for y – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. The present study aimed to investigate the effect of different molting procedures on the post molt performance and some physiological traits. Two hundred and seventy Hy-Line laying hens aged 60 weeks were randomly chosen from a large commercial flock. All hens were approximately of an equal body weight and similar performance. Birds were divided into three by: 5. Forced molting is a starvation practice employed by the US egg industry to manipulate egg laying and the economics of production. It involves the removal of ALL food from hens used for commercial egg production for 5 to 14 days (typically 10 to 14 days) to manipulate the hormones responsible for egg production and feather cover. Organic Poultry Production in the United States Force-molting is a way to induce the layers in a ﬂock to molt at a particular time and at a faster rate. Molt can be forced by reducing the nutrient density of the diet and reducing the light period. but heri- tage breeds have only been selected for egg production or exhibition for the.
