Feeding Space, Population Density and Growth of Young Chickens

Abstract

ADEQUATE feeding space and optimum population density (floor space) are generally considered necessary for maximum growth of broiler chickens. Recommended space allowances vary somewhat, with the recommendations published by the Nutrition Council of the American Feed Manufacturers Association (1952) representing the majority of institutions making recommendations. Their recommendation for floor space per bird is: ½ sq. ft. through 6 weeks and 1 sq. ft. for 7 through 12 weeks. For feeding space per 100 birds the recommendation is: 0–2 weeks 100 linear inches; 3–6 weeks 175 inches; 7–12 weeks 300 inches; these allowances should be increased during warm weather.Less than the recommended space allowance in either category is often referred to as a stress upon the chickens. Frequently in popular articles and talks the suggestion is made that when floor space per chick is below the recommended level, feeding space should be increased. The theory behind …
