Effect of a complex prebiotic preparation on the preservation, growth intensity and microflora in rabbits intestine

Abstract

We presented the effect of prebiotic "Bio-active" on preservation, increase of the body weight, the microflora composition in the distal small intestine, histological examination of the intestinal wall and liver of rabbits gray giant breed 45 days aged. Prebiotic "Bio-active" contains products of metabolism of lactic acid bacteria Lactobacillus bulgaricus delbrueckii adsorbed on zeolite. Our results proved the safety of this prebiotic for the rabbits. Optimal scheme for oral administration of the prebiotic was 2.0 g per 1 kg of body weight for 30 days. Such a course provided 95% of animal preservation and increase in the weight gain of the experimental animals, an average of 43.1% compared with the non-treated rabbits. In scarifies of distal intestine in 20% of animals that received the prebiotic and in 100% of those who did not receive it, Bacteria of Proteus genus have been detected. After the course of prebiotic we registered an increased number of Enterobacteriaceae (4.5–6.0 × 108 CFU) and Bifidobacteria (8 × 107–108 CFU) in rabbits’ intestines. We also mentioned the enhanced gram-positive/gram-negative ratio with a predominance of gram-positive (1:1.17 against 1:2.9 in control group). In case of prebiotic usage, the stimulation of goblet cells’ development was determined in the small intestine walls. Almost 100% of rabbits, who did not receive the prebiotic, had dystrophic changes in hepatocytes (74.5 % of the animals had fatty hepato-dystrophy and 25 % had protein granular dystrophy). We registered that only 25% of the animals had fatty hepato-dystrophy and 15% had protein granular dystrophy among those, which received the preparation.

“…Recently, aseptic canning has become widely in demand. This method [1,3,11] is based on a new principle of heat sterilization of food products. Thanks to the development of a new method of aseptic canning, it became possible to intensify the heat treatment of the product and, as a result, reduce its harmful effect on the quality of the products being canned.…”

“…For the first time (1935-36) on increasing the coefficient of heat transfer from rotating tubes of different diameters (d = 8…50мм) into the air during free convection reported [1,9]. The heat transfer from single tubes located parallel to the axis of rotation at a distance was investigated R = 160 і 330 мм, as well as from tubes rotating around their axis during free convection.…”

“…According to the new method, the influence of the rotation of the can on the heating of its contents was studied. This technique is as follows: the sterilizing effect is determined for one arbitrarily chosen reference mode, according to which the studied products are sterilized, and by comparing the obtained values of A-effects, the efficiency of rotation for a given type of product is judged [1,7].…”

“…Effects capable of destroying microflora also include ionizing radiation [1,6], which have high energy and are able to cause ionization of electrically neutral atoms and molecules and stimulate the same type of chemical reactions in irradiated materials. In practice, two types of ionizing radiation are used -X-rays and γ-rays.…”
