Using of compound feeds in broiler feed additives of
plant resources, activates body's biological functions.
This increases productivity and gives an ability to
make environmentally friendly products. These local
plants feed additives contributing to enrich animal feed
with active ingredients include flour from nettle and
Caspian marine algae. This article is devoted to
studying the composition of nettle from the different
locations of growth in Dagestan Republic and also, to
determine the effectiveness of the use of nettle flour
individually and to how implement it with the
seaweeds flour in feeds of broiler chickens instead of
herbal flour. The studies showed that nettle from a
foothill zone in the flowering period exceeds slightly
the nettle from mountain zone on the content of dry
matter-1.19 % of protein-0.09 % and exchange energy
0.77 kcal/100g. Nettle meal from mountainous zone
also inferiors the foothills in the energy value to 6.81
kcal/100 g. The inclusion of 2% feed meal nettle, 3%
seaweed either alone or in combination of 2% instead
of+3% of alfalfa grass meal resulted increasing
broilers’ body weight 4,60-8,95% betterment survival
to2,8-5,70%, increasing muscle output at 0,56-2,54%
compared with the control group. The protein content
and the amount of essential amino acids in the thoracic
muscle in the test group was to 0.97-2.74%andto1,68-
2,11%, respectively, higher than the control. There was
a significant increasing iodine in thoracic muscles of
experimental groups 119,6-166,07% relative to
control. Based on the results of the research, it is
recommended to include 2% of feed meal nettle and
3% from algae instead of 4% grass meal of alfalfa to
improve the productivity and biological value of
broiler meat and 1 % of cereals
In the work, we present the results of the investigation
of acute toxicity of bio humates obtained by the method
vermicultivation on laboratory animals. In the diets
of farm animals and Pets to fill in the missing nutrients
in the past years, we had an extensive use of various
feed additives. Among them, mineral (macro - and
micronutrients), protein and fat supplements, vitamins,
biostimulants, complex natural compounds (sapropel,
peat), synthetic products (enzymes, hormones, antibiotics,
adaptogens, antioxidants). The search for new
ways of improvement and increase of efficiency of
agricultural animals using feed additives with high
demands on ecology of meat and dairy foods naturally
led to increased studies on the use in livestock farming
of water-soluble alkaline salts of natural humic acids -
humates. Their environmental safety and the unique
ability to improve metabolism and increase energy
cells very positively manifested in living organisms.
Numerous studies Russian and foreign scientists installed
a high efficiency natural humates as biostimulators
and immunomodulators in animal husbandry and
veterinary medicine. Accumulated extensive experimental
material, proving that the use of humates leads
to faster growth of animals, reducing morbidity and
mortality, increase the body's resistance to toxins in
feed and resistance to adverse environmental conditions.
Improving with the help of humates ecological
purity of the ecosystems "water — soil — plant", as
well as the health of birds, animals and fish will ultimately
lead to strengthen health and to prolong human
life as a consumer of agricultural products. Currently,
the livestock market is intensively increasing the humates
produced in Russia and abroad from brown coal,
peat, sapropel. A special place among them has been
occupied by the newest formulations because of a
unique combination of safety, efficiency, and value,
which, thanks to its amazing properties to increase energy cells, stimulate vital processes and to enhance
the beneficial effects of other substances called energine.
They are harmless to animals and humans; do not
have allergologie, anaphylactogenic, teratogenic, embryotoxic
and carcinogenic properties when used in
recommended doses. This allows you to create on their
basis organic natural feed additives and veterinary
medicines for agricultural animals, birds, fish, fur animals
and Pets, and preventive and therapeutic drugs
for humans
Industrial horticulture assumes the most effective use of
the potential of varieties. One of the key factors
determining the yield of garden plantings is the
effectiveness of pollination. To obtain the maximum
yield, it is necessary to ensure maximum pollination
during the flowering period. For this reason, much
attention has been paid to the selection of pollinators.
Crab-apple forms are promising for use as pollinators, so
this work was aimed at identifying the most common
alleles of the self-incompatibility gene in the crab-forms
using the molecular genetic method of analysis. The
object of the study was 29 apple-tree creams and 3 elite
selection forms. They carried out the molecular genetic
identification of alleles S2 and S10, which are among
the most common apple trees in the world gene pool.
Allele S2 was identified in 16 samples (14 forms and 2
elite selection forms), while S10 allele in one
sample (elite form 12/2-20 (24-28)). Data on the allelic
composition of the S gene in the samples studied are of
value for the formation of a genetic passport on the
compatibility of the studied samples of apple with
modern industrial varieties
The article presents the long-term data (2007-2015.)
biometric aboveground plant parts and the estimation of
the prospects of the three introduced botanical species
of juniper and recommendations for their use in
landscape design. We have established very promising,
promising and unpromising varieties for landscaping in
the conditions of the foothill zone of the Krasnodar
region out of 16 varieties of juniper species: China,
ordinary and rock
The article presents the first results of studies of
somaclonal variability, which take place during
cultivation of tea plants tissues and organs in vitro
culture. As a starting material, there was used
morphogenic callus, isolated from the basal part of tea
microshoots, because callus increases somaclonal
variability. An optimized protocol of the nutrient
medium for induction gemmogenesis to product somatic
clones of tea plants in vitro culture was developed.
Morphogenesis calluses, initiated from the basal part of
tea microshoots and subcultured on the nutrient medium
with 6 – BAP – 2,5 ml + gibberellic acid – 1,0 ml +
Tidiazuron – 4,0 ml + Tryptophan – 1000 mg,
distinguished by high rates of induction of
gemmogenesis – 63,3 %. The article studies the effect of
exogenous growth regulators on morphological and
growth indices of tea callus culture in vitro
Were summed up of perennial introductory tests of the
representatives of the family Betulaceae S.F. Gray in
the Botanical Garden SFedU. The 33 species of this
family have been studied for a total. Evaluation of
winter hardiness of the family members showed that
the absolute resistance to the full range of factors
winter have representatives genus Betula, also Alnus
incana (L.) Moench and Corylus colurna L. Species of
the genus Betula and Corylus may be attributed to the
plants having a resistance to drought. The highly
drought-resistant species – Carpinus betulus L., C.
turczaninowii Hance, Alnus incana (L.) Moench and
Ostrya carpinifolia Scop. Less than drought-resistant –
Alnus glutinosa (L.) Gaertn. Most of the tested species
should be attributed to hemixerophytes. The high
degree of defeat by fungal diseases of the species
genera Alnus, Betula and Carpinus makes them
unsuitable for the regional culture. The causative agent
of the disease is a fungus Chondrostereum purpureum
(Pers.) Pouzar. Based on the totality ecological and
biological properties only species of the genus Corylus
remain promising for the culture. For introductory test
it is advisable to attract drought-tolerant species of the
family Betulaceae such as: Alnus barbata C.A. Mey.,
A. rubra Bong., A. rugosa (Du Roi) Spreng., Carpinus
cordata Blume, C. caucasica Grossh., C. caroliniana
Walter, C. orientalis Miller., C. tschonoskii Maxim.,
Betula insignis Franch., B. lanata (Regel) V.N. Vassil.,
B. luminifera H.J.P. Winkl., B. nikoensis Koidz., B.
forrestii Hand.-Mazz., B. utilis D. Don., Ostrya

degree of contamination
The work was done based on the collection of the
natural flora of the Yakut Botanical Garden. The
object of research was the seeds of 22 species of the
family Ranunculaceae. It is known that the seeds of
many buttercup characterized morphophysiological
tranquility associated with hypoplasia of the fetus
(Nikolaeva, 1988; 1999), due to what delayed the
germination of their seeds. Laboratory germination of
seeds of the studied species varies from 0 to 100%.
Among them, we have not found the kinds seeds
which have explosive or fast germination (1 type of
seed germination). The germination of the studied
seeds states ranging from 6-7 days or more. The
studied seeds were evenly distributed between 2 (12
species), and 3 types of seed germination (10 species).
Type 2 is characterized by slow germination, type 3 -
poor germination or lack of it
