Morphometric Measurement, Productive and
Reproductive Performance of Hilly Chicken Under
Intensive Management System

Introduction
Hilly chicken are found in Hilly areas of the Chittagong region and reared for
local consumption and its egg and meat has a unique taste, is regarded as a
delicacy, and is popular among consumers.
Hilly chicken was superior to non-descriptive deshi and naked neck in terms
of body weight gain.
The heavier body size of the Hilly chickens indicated that it can be used as
slow growing meat type chicken in Bangladesh.

Hilly chickens are considered very valuable in the rural communities because they fulfill
major functions and benefits in the livelihood of rural families. Hilly chickens are broody,
able to take care of their own chicks.
The hilly chicken has the ability to adapt, survive, perform and reproduce under harsh,
hot and humid climatic conditions better than the normal feathered birds.
Introduction

I. To study the morphometric characterization of different traits of Hilly
chicken.
II. To reveal their productive and reproductive performance for future
selection and conservation.

Parameters Studied
Morphometric parameters: Comb type, comb color, plumage color, shank
color, eye color, egg color, body length, shank length, and wingspan were
observed in this study.
Production parameters: Body weight at different ages were estimated.
Reproduction parameters: Egg weight, egg length, egg width, age at first
egg laying, body weight at first egg laying, hatchability (%) were measured.

Hilly chicken morphometric characteristics, productive and
reproductive performance are better than that of other indigenous under
proper care and management.
Body weight of Hilly chicken has significantly heavier than that of other
indigenous chicken that may be the alternative protein source in
Bangladesh.
The present study will help to select breeding strategies for Hilly
chicken to increase their productivity.
