dc.description.abstract | Hatching egg production from commercial broiler breeders housed in single and multiple male cages maintained in a naturally and in artificially ventilated houses was investigated. Twelve cages measuring 90x90x60 cm. and housing either 8 or 10 females and a male were compared with four cages measuring 90x180x60 cm. and housing 20 females and 2 males. A phase-feeding energy program utilizing three isonitrogenous diets with different levels of energy; specifically, 2398 Kcal. M.E. (low), 2670 Kcal. M.E. (medium) and 3027 Kcal. M.E. (high) per kg. of feed was studied. Control groups in cages and on floor were fed the medium energy diet. The total number of airborne bacteria per cubic foot of air, including coliforms, also was studied in both types of ventilated cage houses and in litter-floored pens. Egg shell contamination in cage and floor environments was also determined. ... | en |
