ABSTRACT

 A study was conducted on comparative productive performance of indigenous Naked Neck (NN) and Naked Neck Crossbred (NNC) i.e., Naked Neck x White Leg Horn at Poultry and Wildlife Programme, National Agricultural Research Centre (NARC), Islamabad, Pakistan. A total of 72 birds (16 weeks of age) comprising 30 females and 6 males of each breed were divided into six experimental units / replicates (10 females and 2 male / replicate). Separate breeding pen were allotted to each replicate. The birds were fed ad-libitum. The data on body weight, feed consumption, daily egg production, egg weight, egg shell thickness and mortality were recorded. Naked Neck Crossbred (NNC) layers exhibited relatively less body weight (1461g) at 40 weeks of age, better egg -1 -1 production (66.36 %) and feed efficiency (761.32 g feed bird week ) and produced heavier eggs (average weight 60.89g) than those produced by Naked Neck (NN). However, the difference in the feed intake values was found to be non 0.05). The Naked Neck layers produced thicker shelled eggs (0.390mm) and showed better livability than their counterparts.
