The optimal rations have been found. We have
conducted a research on the assessment of meat
productivity, biochemical blood tests. The chemical
composition of blood and meat has been found. We
have empirically chosen a content area for both chicks
and adults of black African ostriches. The article
shows a selection of optimal rations for feeding of
ostriches; we have also determined the live weight of
ostriches in groups, keeping the chicks safe in groups,
hematological studies of ostriches blood, the chemical
composition of the meat, the efficiency of premixes of
Vitafel S
The article describes the evaluation of reproductive,
fattening and meat qualities of pigs of purebred large
white breed (KB), crossbred ewes, derived from
crosses KB sows with boars of steppe type (ST) CM-1
and three-pedigree animals, obtained by crossing
crossbred ewes KB x ST with imported boars of
specialized meat breeds, such as Landrace (L) Duroc
(D) and pietrain (P). We have studied qualities such as
prolificacy, milk yield, live weight of the nest, the
average weight of one Piglet, the safety of the
offspring to weaning, maturity, which is closely
associated with average daily gain in live weight, meat
content of carcasses, their linear dimensions, meat
productivity, the amount of kidney fat, weight of
carcasses of animals of the experimental groups,
carcass yield
An important factor in improving the efficiency of production in the agro-industrial sector is to improve the quality of poultry products and their processing. The article presents the dynamics of the influence of stimulating drugs on the productive qualities of the black African ostrich. The reserves of increasing the production of eggs of black African ostriches and its quality due to the use of stimulating drugs were revealed. The effect of the use of the drug called "Radostin Vitasil" on the chemical composition of eggs, egg production of black African ostriches is shown. The obtained research results convincingly prove that the mass of ostrich eggs of the experimental groups significantly exceeded the control by 5.45 and 3.11%, respectively. Changes in the mass of white and yolk of the egg of ostriches of experimental groups as a result of feeding the drug "Radostin Vitasil" affected the ratio of white/yolk, which slightly decreased towards the optimal. There was a significant difference in the content of carotenoids and vitamin A in the egg yolk of the I experimental group by 10.98% and 10.05%, in the II experimental group-9.15% and 6.35%, in comparison with similar indicators in the control group, respectively. There was an excess of vitamin E level in the eggs of the experimental groups in relation to the control by 6.73 and 3.42%. The results of incubation showed that the stimulating drug "Radostin Vitasil" had a positive effect on the process of embryonic development. The calculated economic efficiency of the drug "Radostin Vitasil" confirmed the feasibility of using this drug in the production of black African ostriches eggs
Experimental studies were carried out on the breeding
farms of "Russian pork" in Millerovo district of the
Rostov region on purebred and crossbred animals
derived from crosses of pigs and the Don steppe types
of meat, breeds of Landrace and Pietrain. The Don
type of meat was used in the experiments as a control.
When crossing, the DM-1 pigs were used as the parent
form, and CT as a father to give twin breed hybrids
DM-1 x ST. The recent delivery of boars of Landrace
and Pietrain breeds allowed to receive twin breed
hybrids of genotypes of CT × L and DM-1 × P
We have selected a group of test animals and formed a
set of techniques for the research. The article gives an
evaluation of fattening qualities (precocity, average
daily gain, feed consumption per 1 kg of gain) of
purebred and crossbred pigs. We present the dynamics
of body weight and body length for the experimental
pigs, productive qualities, the thickness of back fat of
experimental animals to achieve the 100 and 130 kg of
live weight
In the article we have given the complex estimation of the productive and meat quality of genuine Russian pigs of meat types, and crossbred animals received with participation of foreign varieties
The research was conducted at the pure-bred pigs CT and hybrid juveniles CT x L Total protein blood serum was determined refractometrically, protein fraction - a method of horizontal electrophoresis on paper, the level of total lipids - B. Swahn, I. Scand. Researched transaminases (AST and ALT) method of Reitman-Frenkel, alkaline phosphatase - method O.A. Bessey e.a., creatine kinase - S.S. Kuby. Cortisol levels was determined by radioimmunoassay analysis, adrenaline - fluorometric method. Phagocytic activity was installed by Ms. V. Matusevich, bactericidal activity - by the method of Overmoney, T.A. Kuzmina
