摘要

It has been observed that there are differences in erylhrocytic values between laying and non-laying birds. These differences are presumably due to differences in hormonal status. Oestrogen administration, for instance, has been found to result in a decline in the haematocrit of many species including chicken. The difference in erythrocytic values between laying and non-laying birds has been utilized to identify unproductive turkey breeder-hens The most popular system for rearing poultry in Ghana and other West African countries is the deep litter system, where all the birds are kept in one room. With this system, unproductive hens cannot be identified and this becomes a problem especially in flocks over one year old where egg production is low. The aim of this study therefore, was to assess the use of haematocrit, haemoglobin concentration and total red blood cell count in identifying unproductive birds in a flock of old layer hens.
