Description

Known additive to feed for fish, including sodium humate or potassium humate, feed preparation of microbial carotene, phyllophora meal, enzyme preparation and corn gluten or fodder yeast, in the following ratio, wt. %: Feed preparation of microbial carotene - 0.5-1.5 Phyllophore meal - 1.0-2.0 Enzyme preparation - 2.5-5.0 Sodium humate or potassium humate - 1.5-3.0 Corn gluten or feed yeast - the rest (1) Corn gluten contains all amino acids, minerals and trace elements, carothionides, carotene, vitamins E, B2, B3, B5, nucleic acids. As part of the described additive, it had a positive effect on the formation of the reproductive organs of producers, the survival of larvae, and was also used as a filler in an amount of 90% or more by weight of the additive (RF patent No. SU 1629008 A1, published on 02.23.02.1991).

Known bioactive universal premix for feeding rainbow trout "BIOEFECT-FISH", including vitamins: A, D ₃ , E, B ₁ , B ₂ , B ₄ , B ₁₂ , K ₃ , biotin and an antioxidant, characterized in that the premix additionally contains : trace elements - copper, zinc, manganese, iron, iodine, selenium, vitamins - PP, choline, as well as folic acid and dihydroquercetin, with the following ratios included in the premix ingredients:

Trace elements: Copper mg/kg 600 Zinc mg/kg 10000 Manganese mg/kg 200 Iron mg/kg 16000 Iodine mg/kg 160 Selenium mg/kg 60.

Vitamins: A IU/kg 2000000 D ₃ IU/kg 400000 E IU/kg 220 B ₁ Mg/kg 1600 B ₂ mg/kg 3500 PP mg/kg 20000 B ₄ mg/kg 180000 B ₁₂ mg/kg 0.7 K ₃ mg/kg 500 Biotin mg/kg 250 Choline mg/kg 180000 Folic acid mg/kg 500 Dihydroquercetin mg/kg 6000.

A method for feeding the bioactive universal premix "BIOEFFECT-FISH" to rainbow trout, which includes adding the premix to the feed of the main diet, followed by feeding the resulting mixture of rainbow trout, characterized in that the premix is added to the feed of the main diet according to the scheme:

for larvae and fry - 1.2% of its mass;

for adult marketable fish - 1.0% of its mass,

at the same time, sunflower cake in the amount of 70-75% is used as a feed filler for the main diet (RF patent No. RU 2014121188 A, published on 10.12.2015).

Biomar Efico Alpha 790 R was chosen as a prototype food developed for growing trout fish species, including fish meal, soy protein concentrate, soybeans, blood meal, rapeseed oil, fish oil, wheat, fodder beans, hemoglobin flour, wheat gluten, pea protein , vitamin premix, mineral (https://ua.all.biz/korm-dlya-foreli-efiko-alfa-790-3-8-mm-g17849139).

The disadvantages of the known formulations include a large number of expensive components that make up the feed and their frequent falsification.

The task is import substitution and expansion of the range of domestic food products for growing trout.

The technical result is an increase in the absolute, average daily and monthly gain and fatness factor of the trout.

The technical result is achieved by producing feed for trout, consisting of ingredients of animal origin, wheat, blood meal, fish meal, fish oil, and a premix for fish, characterized in that it additionally contains the Beta-flora feed additive, meat meal, meat and bone meal, corn gluten, soybean meal, pork hemoglobin and fodder yeast, as sources of vegetable fatty acids, soybean oil is used, as mineral and vitamin premixes, a premix for trout is used, with the following ratio of components per 100 g of the finished product, g:

wheat 19 meat flour 15 corn gluten 10 meat and bone meal 10 fish flour 10 fodder yeast 10 soybean cake without shell 8 soybean oil 7 fish fat 6 premix for trout 3 porcine hemoglobin 1.5 feed additive "Beta-Flora" 0.5

at the same time, feeding is done manually 3 times a day according to the actual palatability.

Feed additive "Beta-Flora" - crystalline powder, cream color, consists of components of plant origin, which has in its composition essential amino acids and betaine.

GOST 3% premix for fish contains vitamins: A, D3, E, KZ, B1, B2, B3, B4, B5, B6, B12, biotin, folic acid, trace elements: iron, copper, zinc, manganese, cobalt, iodine, selenium, magnesium, antioxidant.

An example of a specific implementation.

Wheat flour - 190 g, meat flour - 150 g, corn gluten - 100 g, meat and bone meal - 100 g, fish meal - 100 g, fodder yeast - 100 g, soybean meal without shell - 80 g , soybean oil - 70, fish oil - 60, 3% premix for trout - 30 g, porcine hemoglobin - 15 g, Beta-Flora feed additive - 5 g.

All ground components included in the compound feed were sieved and a mixture of dry components was prepared. Feed additive "Beta-Flora" was added to the resulting mixture, thoroughly mixed.

Experimental work was carried out in the conditions of the Problematic Research Laboratory "Cultivation of valuable sturgeon breeds" of the Federal State Budgetary Educational Institution of Higher Education of the Volgograd State Agrarian University. As objects of research, 1 control and 2 experimental groups of rainbow trout individuals were used. The initial weight of the experimental individuals was 165 g.

The dynamics of the live weight of trout was determined by the results of weekly weighings, on the basis of which the absolute and average daily gains, as well as fatness coefficients, were calculated.

The analysis and generalization of the experimental materials obtained during the research on the evaluation of the effectiveness of the use of domestically produced protein components in compound feed for trout made it possible to draw the following practical and theoretical conclusions.

As a result of the experiment, the best results in terms of absolute increase in live weight had individuals who received feed containing a feed additive; they outperformed their peers from the control group by 10.42% and 5.82%, respectively. In terms of absolute increase in body length, individuals fed with feed containing Beta-Flora outperformed analogues from the control group by 10.3% and 13.2%.

The largest average daily increase was also recorded in individuals who received feed containing a feed additive; according to this indicator, they dominate over their peers in the control by 11.11 and 7.41%, respectively. The animals of the 3-experimental group also had the best indicators in terms of fatness coefficient, they were superior to their analogues from the control and 2-experimental groups.

Thus, the claimed production feed for trout provides an increase in absolute, average daily gain, absolute gain in body length and fatness factor.
