This book was released on 1970 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of studies was designed to determine the effect of bird numbers per cage and floor area per bird on laying performance. Adrenal weights were also measured on selected treatments. Two strains of commercially available birds, an incrossbred strain and a California Gray x White Leghorn cross, with body weights at housing time of about 1,400 and 1,650 grams, respectively, were used. A total of 1,134 birds of each strain were randomly assigned to three different cage sizes and three densities within each cage size. A general decline in final average body weight and average hen-day egg production occurred as bird density per cage increased. The bird number per cage and floor area per bird had a significant affect on the average egg size, percent large eggs, and feed efficiency. For the strain of incrossbred birds used for this study, three 2 or four birds per cage allowing a minimum of 464 cm of floor space per bird appeared to be the optimum social arrangement for minimum stress and maximum performance. For the California Gray x White Leghorn cross the optimum number of birds appeared to be two or three birds per cage if allowed at least 580 cm of floor space. Floor area per bird appeared to be regulated to some degree by the total body mass within a cage. The adrenal weights based on milligrams of gland per gram of body weight increased as the bird densities per cage increased.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to examine the effect of stocking density (SD) on growth, behaviour, and welfare in 1.) conventional (274-342 cm2/bird) and 2.) furnished (247 335 cm2/bird) rearing cages. SD was adjusted by altering group size. In conventional cages, stocking density significantly affected bodyweight; pullets from lower densities were heavier than those from high densities. Rearing density did not affect feeding behaviour, feather pecking, or aggression. The effect of SD on bodyweight was inconsistent in 3 strains of pullets reared in cages furnished with perches and a platform. Locomotion decreased as stocking density increased, while most other behaviours were unaffected. The proportion of birds perching at night from high densities declined as birds grew, suggesting that perch space became limiting. The results of this project indicate that stocking density may affect growth, the ability to locomote, and night perching, but this is likely dependent on cage design.
