Effects of administration of probiotic on body growth and hematobiochemical profile in growing Barki lambs

AbstractThe purpose of this study was to investigate the potential effect of probiotic supplementation on body growth and selected hematobiochemical parameters of growing Barki lambs. For this reason, twenty apparently healthy weaning lambs were randomly allotted into two equal groups (6 each): the first group (control) received a basal diet without any supplement, whereas the 2nd group (supplemented group) received the basal diet supplemented with probiotic (Bacillus subtilis, sorbitol sodium, vitamin B1, and glucose) which was given via drinking water at a dose of 1 g/L/day for 30 consecutive days. A blood sample was collected from each lamb via jugular venipuncture before starting the experiment (T0) and 15th day (T15) and 30th day (T30) after supplementation for hematobiochemical examination. Body weight and body growth indices of each lamb were calculated weekly. Supplemented lambs had a significant (P< 0.05) increase of body weight (14.5 ± 0.2 kg), length, height at withers, circumference of chest, body proportion, and anamorphosis indices at third and fourth week of experiment. In addition, the supplemented lambs showed a significant (P< 0.05) increase of Hb, RBCs (11.7 ± 0.4), PCV, and WBCs (13 ± 0.05) at T30. Concentrations of serum calcium, chloride, glucose, and urea and the activity of ALT, AST, and CK (301.7 ± 1.4 U/L) were significantly lowered at T30, while concentrations of serum phosphorus, potassium, total bilirubin, and triglycerides were signific...
