The author has studied the efficiency of diets with
kiselgura. Introduction of the kiselgura into the mixed
fodder for chicken-broilers favors increasing of live
weight by 4.8 % and average daily weight gain by 5.0%
The author has studied the efficiency of diets with NATUPHOS 5000 enzyme preparation. Adding the enzyme preparation into the mixed fodder for chicken broilers favors increase of live weight by 4,5 % and average daily weight gain by 6,1 %
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
The influence of four experimental phage preparations, designed based on non-transducing E. coli bacteriophages on pigs with post-weaning diarrhea studied. The influence of these phages in depending by methods of its applying (per os and intra cutis) on coli-titer and coli-phages titer studied. It is established, that the best survival rate and the clinical condition showed animals treated with the E. coli phage T4-type with lab. number «8» (till 5,52 lg CFU/g at 37-days age) in parallel with an increase in titer of phages (till 5,73 lg CFU/g at 40-days age). Intradermal (intra cutis) method of applying of experimental phage preparations (constructed on basis of phage “6” and phage “8”) showed the some positive effects on correction of negative dynamics of coli-phages titer in control group
Zoo engineering expediency of enzymatic agent utilization as part of combined fodder for pigs in their growing and finishing is studied
Application of enzymatic agent MEK CX-3 (as a component of combined feeds for broiler chicks) promotes live weight gain, feed conversion efficiency and safety of young birds
Introduction of the enzyme preparation Roxazym G2 into the mixed fodder for young pigs favours increase of live weight by 5.4 - 7.3 % and average daily weight gain by 6.6 - 9.1 %
Under the current conditions, it is very important to
boost the production of pork and improve its sanitary
and hygienic quality for the successful handling of
problems subjected to import substitution of meat
products. This can be reached by means of
strengthening of food reserve. For that purposes, in the
frame of two experiments yacon tubers in combination
with enzymatic agent protosubtilin GZx have been
introduced in the intakes of fattening pork stores
instead of fodder beat, and various doses of carbitox
adsorbent have been additionally added when
superfluous background of heavy metals was
observed. During the 1st experiment, the substitution of
fodder beet with the similar quantity of yacon tubers
has allowed the animals of experimental group to
outweigh the ones from the control group on 7,5% in
the terms of gross formation of body weight, and to
gain 100 kg of body weight for 7 days ahead of the
animals from control group as well. Additionally,
fodder costs per product have been reduced and the
morphological and biochemical values of animals
blood have been optimized. Based on the data from
2
nd experiment, it has been defined that the better dose
for feeding of adsorbent carbitox was 2,0 kg per tonne
of concentrates thereby the animals of 3rd experimental
group had reasonably higher body weight gain and
thereby higher feed-conversion ratio by products.
Therewith, the animals intermediary metabolism has
been speeded up due to optimization of morphological and biochemical values of blood and reduction of
heavy metals content in blood serum, in other words
level of zinc, lead and cadmium was not exceeding
maximum allowable concentration
To improve the quality, safety and competitiveness
of the domestic raw materials of animal origin the
use of probiotics in the poultry industry is a priority
and promising direction of the development of
organic agriculture. One of the key problems of the
production of probiotics is to provide actively
stable preparations. Biocompatibility of the
indigenous microflora with probiotics, medical
form and individual range of antibacterial activity
of probiotics have a significant impact on the
introduction of probiotics in new habitat conditions
and its effectiveness. Consideration of these factors
can enhance the effectiveness of probiotics.
Currently, the available literature has insufficient
justification of certain doses of administration and
methods of using different probiotic preparations.
The materials present and summarize the results of
the research concerning the use of probiotics in the
poultry industry, based on the achievements of
Russian and foreign scientists. In addition, based
on the analysis of various sources of scientific
literature, we suggest ways to solve the problem of
probiotic therapy and give some recommendations
on the organization of the technological process of
selection and application of different probiotics in
poultryfeeding. Raw meat from poultry reared with
the use of probiotic preparations is safe, because
metabolites of probiotic microorganisms are not
accumulate in the body tissues. Researches of
biosynthesis regularities of probiotics were made at
the cellular level, including genetic aspects,
features of regulation of secretion, dependence on
the cultivation conditions, interaction with binding
sites on the cell surface, participation in the vital
activity of the population of individual cells. The
use of probiotics contributes to normalization of
the intestinal microflora, activation of protein
metabolism, productivity increase, reduction of
feed costs per unit of production and increasing of
poultry industry economic efficiency as a whole
The isolation of E.coli phages from samples of natural
and waste water obtained during expeditions in the
different regions of Russian Federation was carried
out. The obtained phages (286 isolates) were tested for
their ability to lyse the pathogenic strains of E. coli –
pathogenic agents of pig colibacteriosis in Krasnodar
region. The study was conducted of their ability to
phage transduction, the molecular-genetic
characterization and biotechnological parameters of
selected bacteriophages. For first experimental design
of veterinary drugs was selected 5 coliphages having no ability of plasmids transduction. It has been shown
that all the investigated phages are representatives of
T4-type phages of family Myoviridae. The reported
study was partially supported by RFBR, research
projects No. 08-04-99111, 09-04-10132, 16-44-
