Abstract
  • An experiment was conducted to determine the suitability of a new variety of yellow pea (Pisum sativum L., var. Miranda) as a feed ingredient in broiler breeder diets. Two-hundred twenty-five I S A Vedette dwarf broiler breeder pullets were fed either a corn-soy (CS) or corn-pea (CP) diet from day of age to 46 weeks of age . Diets were formulated to be isonitrogenous and isocaloric and were supplemented with D,L-methionine. Treatment groups were reared in adjacent floor pens from day of age to 22 WOA. Following selection based upon uniformity of body weight, Thirty-two pullets from each dietary treatment were placed in individual cages and photostimulated. With the initiation of lay, the following variables were measured: hen-day egg production, egg weight, fertility and hatchability of fertilized eggs. Body weight gain was controlled by restricted feeding, as had been done prior to initiation of lay. No differences were observed (p>.05) in the reproductive parameters measured. Mortality was negligible in either treatment group. This work demonstrates that the Miranda variety of field pea, which can be grown in the Willamette Valley, can be used as an alternative feed ingredient for dwarf broiler breeder pullets.
