Rice blast caused by Pyricularia oryzae is a major disease affecting rice production grown in upland and wetland rice. Application of biotechnological approach to protect against the disease may be an alternative strategy to chemical control
The article analyzes the possibility of complex
processing of one of the most important secondary raw
materials of Krasnodar region – sugar beet pulp with
the aim of obtaining a food product and enriched feed
additives. Meanwhile, the use of environmentally
safety technologies that cause minimal harm to the
environment and human health is provided. One of the
most valuable components of sugar beet pulp after
extraction of sugar is pectin substance. Sugar beet
pectin substances have high complexing ability and are
used not only in food industry, but also in medicine.
They are natural detoxifiers and antioxidants.
Currently, only dry powder pectin is produced from
sugar beet pulp and only by foreign producers. Making
food pectin extracts from sugar beet pulp will not only
reduce the number of processing steps, but also
significantly reduce the cost of the final product. Food
pectin extracts can be used not only as a standalone
product in treatment and prophylactic nutrition, but
also as an ingredient in the manufacture of soft drinks,
confectionery and bakery, meat and dairy products,
etc. The technology of producing a valuable
component of feed bioproduct based on spent sugar
beet pulp and a microscopic fungus of the genus
Trichoderma is described
The purpose of the research is to compare the effect
of a new symbiotic feed supplement created based
on propionic and lactic acid bacteria with a widely
used domestic and foreign enzyme-probiotic
preparations in chickens 0-28 days of age of the
Lohmann Brown egg cross. In the experiment, there
were six groups of chickens: group 1 received basal
diet (BD); group 2 – BD + symbiotic preparation;
group 3 – BD + Bacell; group 4 – BD + Agrocell;
group 5 – BD + Agroksil; group 6 – BD + Ollzaym
Vegpro. Average daily gain, food conversion rate
per 1g of weight gain, digestibility of organic matter,
crude protein, crude fiber, crude fat, made up
respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0,
81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1;
group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4
– 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50,
1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92,
73.2, 67.5, 70.7, 94.3. The growth rate of chickens
fed with symbiotic feed supplement was 2.3%
higher than in the control and they showed the
highest fiber digestibility. The chickens on diet with
Agroksil enzyme efficiently raised growth rate
(+4%) and reduced feed costs (-4.2%). Agrocell
increased weight gain by 2% and reduce feed costs
by 2.6%. The growth rate of chickens fed Ollazaym
Vegpro was the lowest (96.8% of control), despite
the fact that it increased significantly the
digestibility of crude protein, but slightly improved
the digestibility of other nutrients. Outcome:
symbiotic feed supplement may be of interest as a
means of increasing the productivity of chickens
