-Background: Kefir is a natural probiotic food.

It contains a complex mixture of both bacteria, yeasts, many vitamins, minerals, amino acids, and enzymes.

Also It contains numerous bioactive ingredients that give its unique health benefits, for instance, strengthening immune system, metabolism, improving anti-allergic resistance, antitumor activity, improving intestinal immunity, antimicrobial activity, regulation of cholesterol, improving sugars digestion and antioxidant activity.

Aims: The study aimed to investigate the effect of kefir intake on growth performance, and some biochemical profiles among domestic rabbits.

The study design: it was a case-control study.

Materials and method: Kefir starter was obtained from Mrs.

Al Nagar who she is a Physician popular, Nusirat Camp, Slahdeen street.

Experiment was carried out on the rabbits that lived in normal condition, they were divided into three groups (one control & two cases).

All groups matched each other in age, initial body weight, and all other environmental conditions.

The sample included 24 rabbits at of 35 - 40 days.

Each group have 8 rabbits, first group is a control received normal drinking water.

The case groups (T1 & T2) are the rabbits that were drunk water with 10% and 20% Kefir, respectively.

All rabbits were individually weighed at the beginning of experiment then they were individually weighed weekly intervals until the end of the experiment.

Feed consumption of each experimental unit was recorded weekly and feed conversion ratio was calculated.

At the end of the study period, 2 rabbits were randomly selected from each group for slaughter and blood was collected for biochemical analysis.

SPSS system (V20) was used to analyze the obtained data.

Results: The results of the study showed that total body weight gain were similar in control & T2 groups during whole the trial period (p>0.05).

The VI highest growth observed in rabbits that took 20% Kefir milk and The lowest growth observed in rabbits that took 10% Kefir milk at first 4 weeks of growth period.

But when compared with control group, it was non-significant.

The same results was clear after 6 weeks in growth of cases.

Total average daily feed intake, feed conversion ratio were showed a significant decrease among cases compared to control group.

As Kefir concentration increased to 20% of water, there were significant decrease in skin weight, kidneys, spleen, lungs, internal body fats and liver.

In contrast there were significant increase in Caracas, head and viscera weights.

But when increased to 10% of water there were significant decrease in, internal body fats, viscera weights and liver.

On the other hand there were significant decreases in fasting blood sugar, insulin growth factor1, low density lipoprotein, uric acid and free thyroxin as kefir percentage increased to 20%.

In contrast these results, there were significant increased with total cholesterol, aspartate aminotransferase, alanine aminotransferase among groups.
