Abstract:
Chitosan is in nature the widest widespread organic from compounds one was
polysaccharide natural polymer. It is made release for raw material chitin, crustaceans epidermis
structural polysaccharide, insect’s cuticles and fungal cell walls is. Current restrictions on the use of
this component are explained by the insufficiently developed production base for drying whey,
ensuring its quality stability and production capacity. The following main directions of processing
and use of whey can be distinguished: use of whey in its natural form, processing and application in
the form of condensed concentrates, separation of its important components (protein, lactose) using
membrane methods, biological purification of whey, processing and use in the form of dry
concentrates.
Key words:
Chitosan, chitin, dry whey, sorption, sorbent, broiler, protein, whey.
Introduction.
The history of research on chitin and chitosan dates back about 200 years (chitin was
discovered in 1811, chitosan in 1859). Chitosan and preparations based on it are successfully used in
veterinary medicine to treat diseases of farm animals and poultry and to increase their productivity
[1].
Structurally homogeneous biocompatible and biodegradable composite materials were obtained
based on blends of high-strength chitosan with 8-block copolymers of D, L-lactide chitosan [2].
However, the metabolism and physiological status of broiler chicks fed with chitosan and whey
powder as part of the feed has not been studied much with modern breeding technologies. The
optimal doses for its addition to the feed at different stages of production have not been determined,
and therefore there is no clear understanding of how this affects physiological status, productivity,
product quality and economic efficiency.
The aim of the study
was to assess the adequacy of protein and energy nutrition to meet the
physiological needs of Cobb broiler chicks when fed chitosan and whey powder.
Literature analysis.
Some polysaccharides, including chitosan, are attractive for use in food due to
their properties. Chitosan, when introduced with food, is able to be enzymatically degraded and
assimilated in the form of low molecular weight compounds. Chitosan oligomers affect nonspecific
resistance factors that stimulate the immune system [3,4].
The role of biologically active substances of natural origin in increasing the efficiency of complete
feeding of broiler chicks is discussed in detail, and scientific development of methods for activating
the immune system and metabolic processes in industrial broiler chicks is proposed [5].
BS feed of the suffix broiler chicks liver to the state impact studied. BS feed addition in use in the
liver happened to be processes histological check and comparative check control and experimental
in chicks physiological, compensatory and pathological processes complex [6,7].

To date, research is underway to find various feed additives that maintain the normal physiological
state of birds, prevent the development of diseases, accelerate growth without harming their health,
and increase their productivity by affecting the intensity of reproduction of genetic information [8].
Traditional feed additives for poultry from microalgae of the genus Chlorella and chitosan has been
considered. A balanced diet for farm animals can reduce their morbidity, increase their weight, and
increase milk production [9].
In nature 2 types of sorption available: adsorption and absorption. Adsorption - sorbent hard
particles the surface to tie ability, absorption - sorbent whole size according to absorbed of the
substance adsorption. Adsorbents mainly village animals and poultry in feeding is used [10].
Sorbin to the feature has the widest widespread feed additions aerosil, bentonite, tripoli, zeolite,
vermiculite, glauconite, diatomite and others mineral supplements such as [11].
Food sorbents various kind toxic substances quickly to tie ability has. Sorbents at different pH
values stable and feed in granulation is thermostable. Sorption to the feature has was many feed
additions vitamins, micronutrients and macronutrients does not bind [12].
Sorbent feed additions many from mycotoxins outside pathogen bacteria toxins, heavy metals ions
and radioactive compounds to tie to the feature has [13].
Chemical to nature according to feed sorbents one how many to groups to be possible, carbon based
on sorbents, natural and synthetic resins or to oils-based sorbents, silica based on sorbents, lignin,
chitin, pectins based natural sorbents and combined sorbents [14].
The issues of increasing the crude protein content and improving the amino acid composition of
biomass remain open and require further research. In addition, the study of the effect of such protein
on the physiological and productive parameters of broiler chickens is of scientific and practical
importance. The aim of the work is to develop a method for obtaining alternative feed protein with a
high crude protein content and improved amino acid composition [15,16].
The effects of methionine and whey powder on the storage parameters, average total weight,
distribution of broilers by category, and chemical composition of meat were studied. When
methionine was added to the basic diet, the survival rate of chicks and roosters increased by 0.3%,
the average weight of chicks after 30 days - by 10.03%, and roosters - by 6.25%, after 60 days
[17,18].
Studies have been conducted on the use of high-protein feed additives for growing broiler chicks
from secondary raw materials from "organic" processing industries, and optimal standards have
been determined, and their effect on the growth, development, and meat quality of poultry has been
studied [19.].
Currently, various ingredients are included in the diet as feed additives. Whey has been studied in
poultry diets and a skim milk powder enriched with microbial proteins and vitamins has been
obtained [20,21,22].
The possibility of using whey powder as part of a mixed feed for broiler chickens was studied. In
the experimental groups, 3.5 and 10% whey powder was introduced into the feed for chicks instead
of feed yeast and corn and wheat grains. Birds in the control group received a standard compound
feed enriched with microelements and vitamins based on current recommendations. The inclusion of
3 and 5% whey powder in the compound feed helps to increase the live weight of chicks and reduce
feed costs [23,24,25].

Whey, due to its content of the indigestible disaccharide lactose (85% of dry matter), is not used in
sufficient quantities for feed, as a result of which most of it is dumped and pollutes the environment.
It is known that one cubic meter of whey, when released into water, contaminates 1000 m
3
of water.
In this regard, the development of simple and advanced methods for processing whey will allow
expanding the production of valuable feed [26,27,28,29].
Particular attention should be paid to the possibility of using whey in some formulas of whole milk
replacers, which allows saving equivalent amounts of skim and whole milk for food purposes and at
the same time obtaining a product with high nutritional value [30].
Whey, a by -product of cheese, cottage cheese, and casein production, is a valuable food raw
material, from which a complete nutritious dairy products and semi-finished products can be
obtained. All components of whey Full utilization allows the production of products for both direct
consumption and long-term storage. Separate use of components allows the extraction of milk fat,
protein complexes or their individual fractions, lactose, and mineral salts [31,32].
Conclusion.
1.
Premix, mycotoxins, heavy metals and bacteria metabolic products as a sorbent for and
gastrointestinal tract mucus floor surrounded to take tool as, their chick to the div entrance This
reduces the productivity to increase and of meat biological value to increase take is coming.
2.
Premix under the influence broiler of chick’s safety and productivity and his/her meat to the
quality the impact study according to taken information this shows that his the most acceptable dose
80 mg/ dose per day solution is to drink.
