Abstract/ Executive Summary:

This study was carried out to evaluate the effects of supplementation of commercial layer feed on body weight, egg production and haematological profile of the laying ducks rearing under the rural condition of Bangladesh. Twenty indigenous ducks (Khaki Campbell x Local duck) of 24 weeks old was selected from a farm and randomly divided into four equal groups (n=5) and numbered as group T₀, T₁, T₂ & T₃. The different amount of feed was supplied into four groups for three months. The all four groups (T₀, T₁, T₂ and T₃) were fed with routine feeding in scavenging condition. But T₁ group supplemented with 120 gm, T₂ group 60 gm and T₃ group 30 gm of commercial feed. Significant differences were found in both egg production and haematological profile of ducks in compared to control group. Egg production was significantly (P<0.01) higher in T₁ group compared to other groups. During the study the body weight gain were shown the same pattern being significantly (P<0.05) higher in T₁ group compared to T₀, T₂ and T₃ groups. On the other hand, the values of total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin content (Hb) and packed cell volume (PCV) increased significantly (P<0.05) in the groups of T₁ and T₂ compared to the control group (T₀). But the value of MCV, MCH and MCHC of T₁, T₂ & T₃ groups decreased significantly (P<0.05) than that of the control group. Results of the present study revealed that the amount of supplementation of commercial layer feeds was very important for improving the haematological profile and egg production of ducks. So, the additional commercial layer feed supplementation may be beneficial for duck farming.

Objectives:

To assess the egg production potential and haematological parameters of native duck under scavenging conditions with different level of feed supplementation.

Methodology:

This study was conducted at Ajmiriganj Upazilla of Habigonj district in Sylhet division. Twenty laying indigenous ducks ( Khaki Campbell X Local duck) of 24 weeks old was collected from a farm and randomly divided them into four equal groups (n=5) and numbered them as group T₀, T₁ ,T₂ & T₃. Four different level of feed supplementation were considered for four different treatments. The treatment was continued until the peak production reached that is 34 weeks of age. So the rearing period of these ducks was 3 months (March-June) and observed the result for this period. The laboratory analysis of the experiment was done in the District Veterinary Hospital, Habiganj, Sylhet and Horekrisno Diagnostic Center, Ajmiriganj, Habiganj. The following methodology was adopted for performing the experiment. The research work was conducted using twenty indigenous ducks of 24 weeks old. First; all ducks were treated with anthelmintic piperazine citrate, doses of 1 gm for 7 ducks. After seven days of deworming, all ducks were vaccinated against duck plague virus disease. The ducks were grouped randomly as T₁, T₂, T₃ and T₀. Each group comprised of five ducks and was allocated to different respective treatment. The initial body weights of each duck were recorded. The egg production, body condition, body weight and haematological parameters were also recorded on post treatment. Each ducks of every group were leg banded with 4 different colour, T₁ was pink banded, T₂ was red banded, T₃ was black banded and T₀ was green banded. Except the T₁, the other three treatments were colour sprayed on their head similar to their leg band to identify the particular eggs from particular duck. Four coloured signature pen similar to the leg band colour were used to give mark in the egg. We had collected commercial layer feed from Nourish Feed Company for treating the experimental duck. Four different level of feed supplementation were considered as four different treatments. Treatment-1 (T₁) was supplementary feed (120 g) with intensive feeding condition, Treatment-2 (T₂) was 60 g of feed with scavenging feeding and Treatment-3 (T₃) was 30 g of feed with scavenging feeding condition and Treatment-4 (T₀) was fully scavenging without additional feed. Daily feed supply was weighed into polythene bags with 120 g, 60 g and 30 g. Then the packets of feed were distributed among the group. In the early morning when the birds were taken from night shelter to the pens, half of the feed from 120 and 60 g were given to the T₁ and T₂, but in T₃ the whole amount (30 g) were given to the bird. Rest of the feed from T₁ and T₂ was given at afternoon (2 pm). During the time of feeding the door of T₂ and T₃ were closed to make sure that no feed waste was in the feeder. Blood was collected aseptically with sterile syringe and needle either from heart or from the wing vein of four different groups of birds. Immediately after collection, blood was transferred to sterile test tube containing anticoagulant (EDTA- .2 mg / ml of blood). The hematological studies were performed within five hours after collection of blood by method of Lamberd and Rothstein [6]. Haematological studies were total erythrocyte count (TEC), total leukocyte count (TLC), estimation of hemoglobin (Hb), determination of packed cell volume(PCV), determination of erythrocyte sedimentation rate (ESR), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). The obtained results were statistically analyzed using the standard computerized procedure Microsoft Excel-2010 for determination of mean, standard deviation, level of significance, standard error.

Achievement/Findings:

The supplementation of commercial layer feed is helpful for improving hematological parameters and reproductive performance of indigenous duck. However, the amount of supplementation is also dependent on location and availability of feed resources around the farmer’s house. Better economic condition of farmer and enough feed resources around farmer’s house may need less feed supplementation. Further research should conduct to achieve more information among this field for profitable duck farming in the Haor area of Bangladesh.
