Abstract/ Executive Summary:

An experiment was conducted to study the hematological parameters in Fayoumi, Assil and Local Chickens of different ages reared in Sylhet region. 250 chickens of three breeds (100 Fayoumi, 50 Assil and 100 Local) were tested at different ages (1, 3, 6, 9 and 12 months) to observe the hematological parameters: i) Total erythrocyte Count (TEC) ii) Packed Cell Volume (PCV) iii) Determination of Hemoglobin (Hb) iv ) Erythrocyte Sedimentation Rate (ESR) v) Differential Leukocyte Count (DLC) vi) Mean Corpuscular Volum e (MCV) vii) Mean Corpuscular Hemo globin (MCH) viii) Mean Corpuscular Hemoglobin Concentration (MCHC). Erythrocyte numbers, hemoglobin concentration and packed cell volume increased with the advancement of age in all three breeds. The TEC was higher in Fayoumi. The hemoglobin concentration was high in Assil. The PCV was slightly different or similar in all three breeds. ESR was inversely related to the age. Higher ESR in early age and lower in the advancement of age. The Fayoumi showed the higher ESR compared t o other tw o breeds. The ESR of last two groups (9 and 12 months) of Assil and all groups of Local Chickens were negligible. Lymphocytes and heterophils were two principal leukocytes, which exert their dominance on other leukocytes. Among three breeds Local chickens possess the higher lymphocyte percentage. The heterophils were higher in Fayoumi breed. Monocyte was lower in Assil and Local chickens. Eosinophils were higher in number in local and Assil compared to Fayoumi. Higher MCV was recorded in Local chickens followed by Assil and Fayoumi chickens. MCH values were near about similar in Assil and local chicken bu t lower in Fayoumi breeds. The MCHC values of all three breeds were almost nearer to each other. The above study has highlighted some of the normal hematological parameters of chicken mostly reared in Sylhet region. However, more detailed study could be conducted in this regards.

Keywords: Haematological parameters, Chickens (fayoumi, Assil, Local breed)

Location: Sylhet region

Start Date: 00-07-2001

End Date: 00-06-2002

Program Area: Animal Health and Management

Commodity: Chicken

Objectives:

To find out the effect of age and breed variation in hematological parameters of Chickens.

Methodology:

A total of 250 chickens of different ages of three different breeds (Fayoumi, Assil and Local) randomly collected from Sylhet City and its surroundings of Bangladesh were used in this experiment. The experiment wa s carried out from July 2001 to June 2002. Two hundred and fifty apparently healthy chickens of different ages of three different breeds (Fayoumi, Assil and Local) reared in Sylhet region in Bangladesh were used for this study. Among them the number of Fayoumi, Assil and Local were 100, 50 and 100 respectively. The chickens were again divided into five subgroups based on age; 1, 3, 6, 9 an d 12 months old. Blood was collected aseptically with sterile syringe and needle either from heart or from the wing vein of different groups of chickens depending on age randomly. Immediately after collection, blood was transferred to sterile test tube containing anticoagulant 1:10 (4% sodium citrate solution). The hematological studies were performed within short time as possible in FDIL (Field Diseases Investigation Laboratory), District Veterinary Hospital, Sylhet and in the Physiology Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh. Results obtained were statistically analyzed. Mean standard deviation and analysis of variance were calculated according to the standard procedures and the data were analyzed using completely randomized design (CRD) according to Steel and Torrie (1980) with the help of a computer package MSTAT.
