CARCASS CHARACTERISTICS OF GRAMAPRIYA BIRDS UNDER DIFFERENT SYSTEMS OF MANAGEMENT

Abstract

In semi-intensive system of management, the dressing percentage with giblets was observed to be maximum (75.00±0.66 %) followed by deep litter (74.16±1.02 %) and backyard (73.88±0.49 %) system of management of male birds. In case of female the values were 67.201.44 %, 63.97±0.64 % and 66.04±0.78 % respectively under deep litter, semi intensive and backyard system of management. In semi-intensive system of management, the dressing percentage without giblets was observed maximum (71.75±0.64 %) followed by deep litter (71.05±0.98 %) and backyard system of management in male birds. The corresponding values in case of female birds were 59.53±0.68 %, 62.51±1.52 % and 60.93±0.61 % under semi-intensive, deep litter and backyard system of management. The effects associated with different systems of management were observed to be significant in defeathered weight (%) in female, breast (%) in female and giblet (%) in male.
