Study the effect of using probiotic (VETLACTOFLORUM)‎ on some of biochemical and immunological parameters of broiler chickens

Abstract EN

In the present study its used liquid preparation of probiotics "Vetlactoflorum-M" (dissolved in diluted milk) and "Vetlactoflorum-C" (dissolved in whey), and were studied its effect on some parameters such as total protein, globulin, albumin also serum bactericidal and lysozyme activity.

One hundred fifty broilers chicken breed "Ross-308" used in one day old.

They were divided into three groups of 50 chicks (control "un-supplemented with probiotic", first treatment group received “Vetlactoflorum-C” and second treatment group received “Vetlactoflorum-M”).

Blood samples were taken in 7, 14, 21, 28, 35 and 42 day-old.

Laboratorial analyses were conducted in Vitebsk state academy of veterinary medicine in Belarus.

Level of total protein in the 2nd group to the end of the study was higher than in control group to 8.1 % (P < 0.05) in the third group by 3.96 % (P < 0.01).

During observation period in chicken’s serum of supplemented probiotic groups, albumin concentration was higher relative to the control group.

Similar results were observed in level of globulins.

In day 42 of broilers chicken, globulin content in both treatment groups compared with the control group as higher by 2.97 % (P < 0.01) and 5.19 % (P < 0.05), respectively.

The level of serum bactericidal activity in 42 day of 2nd group was higher than the control at 23.62 % (P < 0.01), and in the third group by 16.21 % (P > 0, 05).

The index of serum lysozymal activity also surpassed control group in chickens in group 2 by 11.96 % (P > 0.05), and in the third group at 10.69 % (P > 0.05).
