The article proves a positive effect of feeding with saffron cake and premix based this substance on growth and development, nutrient utilization ration, morphological and biochemical parameters of blood of calves of black-motley breed
Modern commodity sturgeon breeding is one of the
profitable and dynamically developing directions of
fish farming in the Russian Federation. Only the
system of Rosrybhoz has more than 40 enterprises of
different ownership forms for the cultivation of
sturgeons. In 2012, in agricultural farming of the
Russian Federation we had grown more than 2.0
thousand tons of sturgeon. Crucial role to maintain
normal functioning of the body of the fish when
grown in closed recirculation systems plays complete
and balanced nutrition. Proper organization of
biologically full feeding of fish helps to maximize
expression of their genetic potential. The article
presents the results of the researches of the efficiency
of using feed concentrate from vegetable raw
materials called "Sarepta" in the composition of feed
additives for 2-year old Russian sturgeons
This article presents the results of using "Gorlinka"
mustard protein-containing feed concentrate, instead
of sunflower meal in the feeding of broiler chickens
of the cross of "Cobb-500". The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm of the Ilovlinskiy district of the
Volgograd region. Replacing sunflower meal with a
product of processing of oilseeds which is "Gorlinka"
mustard protein-containing concentrate, in the feed
mixture in the experimental broilers had a positive
impact on the productivity, physiological state of the
birds, product quality and economic performance.
The use of this mustard protein-containing feed
concentrate in feeding of meat birds contributes to the increase of live weight by 3.46-of 6.65% and
slaughter yield by 1.38-1.98% and improvement of
quality indicators of the carcasses. Morphological and
biochemical parameters in experimental broiler
chickens in all the groups were within the
physiological norm, which indicates a normally
occurring redox processes in the poultry organism.
However, adding "Gorlinka" mustard proteincontaining
feed concentrate into experimental feed for
broiler chickens contributed to the increase in the
content of total protein, calcium, phosphorus in blood
serum in comparison with analogues from the control
group that received sunflower cake. As a result of the
research, the economic effect in the experimental
groups was up 710,40-1085,53 rubles
This article presents the results of the impact of
"Gorlinka" mustard protein-containing feed
concentrate in the feeding of broiler chicken of the
cross of "Cobb-500" on their performance and
nutrient digestibility of the feed. The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm in the Ilovlinskiy district of the
Volgograd region. Full or partial replacement of
sunflower meal with "Gorlinka" mustard proteincontaining
feed concentrate in the feed mixture for
the experimental broiler chickens contributes to the
increase of the coefficients of digestibility of nutrients
compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed
concentrate in the composition of feed for broiler
chickens has contributed to higher coefficients of
digestibility of nutrients: dry matter – 0.51-1,37%,
organic matter – 0.6-1,99 %, crude protein by 0.8-
2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94-
2,29%, compared to the birds in the control group.
Nitrogen balance was positive in all groups; the use of
nitrogen from the accepted experimental broiler
chickens was higher in the experimental groups than
in the control by 2.89-of 7.93 %. The use of nitrogen
from digested nitrogen was higher in the experimental
groups in comparison with the analogues from the
control group by 2.65-of 7.97 %. The use of calcium
and phosphorus by poultry was also higher in the
experimental groups
This article presents the studying results of new premixes of domestic production using efficiency based on processed products, in particular - oil cakes. The research was carried out in the conditions of the second-order pedigree reproductor in LLC "Svetly" in the Svetloyarsky district of the Volgograd region in the period from 2015 to 2017. During the scientific and economic experience, the authors revealed the new fodder additives positive influence on the laying hens’ egg productivity, on the eggs morphological and incubation rates and on the got young birds. The use of premixes in layer diet, which included the fodder concentrate from the plant raw material "Sarepta" and Camelina seed oil cake, contributed to the increase in the hens laying capacity, in general, the group received in 249 and 310 pieces more than in the control one. The egg average weight from the chickens of the control group was 60.89 g; from the first experimental it was 61.33 g; from the second experimental it was 61.39 g, which was higher than in the control one, respectively, by 0.44 g and 0.50 g. While the hatching eggs morphological indices analysis, it was revealed that all parameters are within the permissible limits of the physiological norm. Fertilization of eggs in the control group was at the level of 89.33%, which is lower than in the experimental groups. As a whole, the eggs' production in groups was 20.00% in the control, 17.33% in the 1st group, and 16.00% in the 2nd test group
The article has scientifically substantiated and experimentally
proved high efficacy of using sorghum grain
and chickpea grain in the diets of cows of Ayrshire
breed. It has also shown their influence on the productivity,
digestibility and utilization of nutrients of diets
The researches on the mustard protein-containing fodder concentrate "Gorlinka" use were carried out during 2015-2016 in the laboratories of Volgograd state agrarian university, as well as at LLC "Donagrogaz" in the Frolovsky district of the Volgograd region. During the research, the authors studied the new high protein fodder additive influence on the digestibility and feeds absorbency, as well as on the blood morphological and biochemical parameters. During the research, it was established that the used fodder additive has a positive influence on the dynamics of the digestibility coefficients and the nitrogen balance. During the physiological experiment, all the experimental cows had a positive nitrogen balance, in the control group it was 9.8 g (the lowest value), in the second group, it was 12.6 g, and in the first one, it was 12.0. When determining the experimental animals’ blood biochemical and morphological parameters the content of the studied components corresponds to the physiological norms. The average daily milk yield for the analogues from the 1st test group was higher as compared to the control, by 1.01 kg, or 5.1%. The mean daily milk yield of the control group was also lower than for the cows of the 2nd test group by 1.45 kg, or 7.4%
The right balance of essential amino acids and protein is the main condition for the optimization of weight gain, feed conversion and high profits. In VGC "Megamix" the quality of different types of raw full-fat soy, wheat, corn, meat and bone meal and fish was assessed on the content of amino acids on the IR analyzer of FOSSNIR Systems company. Amino acid content in the feed does not always match the average standards of reference. So in the reference data content of methionine, threonine and phenylalanine in wheat, indicated 0.23%, 0.43% and 0.64% respectively, and studied in the laboratory of VGC "Megamix", respectively, 0.24%, 0.45% and 0 73%, that is 0.01%, 0.02% and 0.09% higher of tabular values. The lysine content of the wheat to be investigated in a laboratory and provided in the averaged data was on the same level. Thus, the calculation of the recipes should be carried out taking into account not tabulated values but the actual, which will reduce the so-called "safety stock" to get food of consistent quality and reduce the cost of the cost of animal feed, which in turn affects the economic efficiency of livestock production
The researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use
Side products obtained during processing of many oil
crops, have a high feed value and use in rations of
animals and birds. The important thing in feeding
poultry is protein nutritional value of forages and
their biological integrity, expressed in amino acid
composition. In this regard, there was a comparative
analysis of the chemical and amino acid composition
traditionally used in compound feeds for poultry,
sunflower cake, and previously unexamined mustard
protein-containing feed concentrate called "Gorlinka".
During the research, it was found that the studied new
feed additive is better comparing to sunflower meal,
considering protein content and essential amino acids
