|Abstract: ||One hundred day old Hubbard broiler birds were used to investigate the effect of probiotics (Lactobacillus bulgaricus) administered through drinking water on some haematological indices. The birds were divided into three treatment groups each with two replicates. The three treatments were designated as T1, T2 and T3 representing no probiotics (control), probiotics administered fortnightly and probiotics given weekly respectively. The experiment lasted for 63 days. The experimental design was completely randomized design. The birds were all given the same starter diet (CP 22%; energy 3000Kcal/Kg) and the same finisher diet (CP 20%; energy 3200Kcal/Kg) respectively. The parameters measured included haemoglobin (Hb), packed cell volume (PCV), red blood cell count (RBC), white blood cell count (WBC), blood total protein (TP), albumin and blood triglyceride. Results revealed that, Hb, PCV, RBC, WBC, lymphocytes, TP and blood triglyceride were significantly affected (p<0.05) by the treatment while albumin and neutrophil count were not significantly affected (p>0.05) by the treatment at the starter phase of the experiment. At the finisher phase, TP was not significantly affected (p>0.05) by the treatment while the other parameters evaluated were all affected (p<0.05). It was concluded that the administration of probiotics did not have any negative impact on the haematological indices studied and in fact, it led to improved immunity as attested to by higher levels of WBC.|
