Studies On Stress Induced Effects In Broilers Following Vaccination (Nobilis Ma5 + Clone 30) Against Infectious Bronchitis and Newcastle Disease

by Saima Irum Syed | Dr.Asim Aslam | Dr.Sameera | Dr.Shakil Akhtar Khan | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2000Dissertation note: This study was intended to detect the stress induced by live, freezed-dried vaccine against Newcastle disease and infectious bronchitis disease viruses in broilers and to determine the comparative efficacy of vitamins and aspirin to combat it. One hundred and sixty day-old chicks were divided into four group i.e. A, B, C and D having 40 birds each. The birds were kept for 42 days after vaccination with Nobilis Ma5+Clone 30 by eye-droppings on 1st and 22nd day of age. Chicks from group A was kept as control. Group B was given vaccine and no treatment. Group C was given vaccine and only vitamins (Vety Stress-Check). Group D was given vaccine and only aspirin. Ten birds from all groups were randomly selected to collect the serum samples from blood on 1st, 14th, 28th and 42nd day of antibody titre determination. The following parameters were studied (1) antibody response against Newcastle disease vaccine, (ii) Serum bio-chemical substances (Total serum protein, glucose and cholesterol), (iii) Heterophil/ lymphocyte ratio, (iv) Adrenal/body weight ratio (v) Gross histopathology of adrenal glands and (vi) the economics of the flock. The live virus Newcastle disease vaccine had no significant stressor effect on any of the above parameters. However, use of vitamins played vital role in combating the vaccination stress, because it showed immuno competent effect and also positive trend in growth traits. That is why this group showed better economic value than the rest of the groups. The effect of Aspirin was also variable.

Studies On Stress Induced Effects In Broilers Following Vaccination (Hydro Poultry) Against Hydropericadium

by Gulbeena Saleem | Dr. Shakil Akhtar Khan | Dr.Asim Aslam | Dr.Sameera Akhtar | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2000Dissertation note: The project was aimed at determining the vaccination stress follow hydropericardium syndrome vaccine (hydro-poultry vaccine, simple vaccine; Adenovirus type-4 Pak) by subcutaneous route under wing at 12th day of age and comparative efficacy of multivitamins and aspirin to combat it. One hundred and seventy day old broiler chicks were divided into four groups i.e. A, B, C and D having 40 birds each. Ten-day old broiler chicks were used for collection of blood sample by cardiac puncture for detection of maternal antibody titre. Birds were kept for the period of 42 days. The birds of group A served as unvaccinated, unchallenged control. Group B was given vaccine and no treatment. Group C was given vaccine and multivitamins for 3 days post-vaccination group D was given vaccine and aspirin for 3 days post vaccination. Blood samples were collected from 10 randomly selected birds from each group at different post vaccination (Against HPS) periods i.e. 24, 48 and 72 hrs for serum biochemical analysis and 10 birds from each group at 14th 28th ad 42' days for determining antibody response against hydropericardium syndrome. 10 birds of each group were slaughtered on 42 days for collection of adrenal glands. The following parameters were studied (1) determination of heterophil/lymphocyte ratio (ii) estimation of serum biochemical analysis (Total Serum Protein, serum glucose, serum cholesterol). (iii) determination of adrenal body weight ratio (iv) gross pathological and histopathological examination of adrenal glands (v) estimation of antibody response against hydropericardi um syndrome vaccine. Inactivated virus vaccine against hydropericardium was unable to induce any stress in broiler chicks and the above mentioned parameters can act as good indicators for detection of vaccination stress to some extent. Multivitamins played a minor role in improving the condition of bird whereas, aspirin did not seems to be much effective in this study.
