Abstract

The experiment aim to evaluate error induced ND-Lasota vaccination haematological changes and performance in three (3) genotypes of exotic chickens. The experiment which lasted for four (8) weeks was carried out at the teaching and research farm of Niger Delta University Wilberforce Island Bayelsa State. A total of seventy five (75) unsexed day-old exotic chicks were purchased from Federal University of Agriculture Abeokuta (FUNAAB), Ogun State. The experimental birds were randomly picked and segregated into three (3) groups (T1broiler birds, T2Isa brown and T3Noiler birds) which had a control each according to their genotypes with each group housing twenty (20) birds in a Completely Randomized Block Design (CRBD). Each control group housed five (5). Experimental birds were fed starter mash from day old to fourth (4th) week of age and Growers mash from 5th week to 8th week. Feed and water were supplied ad-libitum to birds throughout the experimental phase. ND-Lasota Vaccine was orally administered to birds in each group excluding the controls in each group beginning at the 5th week and ended at the 8th week. Blood samples were collected from experimental birds with 2ml syringe and transferred into non-vacuum tubes on the Day 0, 7th, 14th, and 21st of pre-infection and post infection for determination of haematological parameters. Data obtained were subjected to one-way ANOVA using MINITAB version 16 software and the means were separated using Turkey Test at (P < 0.05). At the end of the experiment statistical analysis showed significant difference (P < 0.05) for performance parameters from Day 0 to 21st of experiment, the best performance in terms of Average final weight was recorded in T3NB 525.0 ± 29.5a and the least was recorded in C-IB 347.0 ± 18.5a although, T1BB and C-BB had no data recorded. However, WBC was slightly high at the end of the experiment with C-NB 3.600 ± 0.766a been the highest and T2IB 2.500 ± 0.764a recorded the least. In conclusion, ND-Lasota vaccination error induced haematological changes and performance in three (3) Genotypes of exotic chickens has proven to adversely affect the performance of bird as their growth were impaired, mortality recorded as their immune system were compromised. I recommend that farmers adhere to the right stocking density in poultry farming so as to cub disease outbreak in farms. I also recommend proper handling of birds and elimination of wrong vaccination among the poultry industry as it tends to pose deleterious effect on birds performance.
