Description

The invention relates to fish farming, fish farming methods, in particular to issues of trout feeding.

Known invention related to feed production, in particular to the production of feed with increased energy value for trout. The method includes additionally introducing fish oil into the granulated feed. The introduction of fish oil is carried out at a mass ratio of granulated feed: fish oil as 10: 1, before the introduction of fish oil is heated, with continuous stirring, combine the fat with the granules and the resulting product is cooled. The addition of fat to the feed leads to an increase in its calorie content, a decrease in protein consumption for energy purposes, which ultimately leads to an increase in the intensity of fish growth. A method of increasing the energy value of mixed feed for trout, including additional introduction of fish oil into the feed pellets, characterized in that the fish oil is introduced at a ratio of the pelleted feed: fish oil mass as 10: 1, before the introduction of the fish oil is heated to 50-70 ° C, with continuous stirring for 5-7 minutes, fish oil is added to the feed pellets and the resulting product is cooled to 15-20 ° C (RF patent No. RU 2108732 C1, published on 20.04.1998).

Known bioactive universal premix for feeding rainbow trout "BIOEFFECT-FISH", which includes 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 of 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 2,000,000 D ₃ IU / kg 400,000 E IU / kg 220 V ₁ mg / kg 1600 V ₂ mg / kg 3500 PP mg / kg 20,000 V ₄ mg / kg 180,000 B ₁₂ mg / kg 0.7 K ₃ mg / kg 500 Biotin mg / kg 250 Choline mg / kg 180,000 Folic acid mg / kg 500 Dihydroquercetin mg / kg 6000

A method of feeding rainbow trout bioactive universal premix "BIOEFFECT-FISH", 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 following 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 is used as a filler for the main diet in an amount of 70-75% (RF patent No. RU 2014121188 A, published on December 10, 2015).

For the prototype, a production compound feed for sturgeon was chosen, consisting of fish flour, white lupine product, wheat flour, premix and vegetable oil, characterized in that it additionally contains blood meal, feed yeast, as a lupine product a protein concentrate "Agro-Matic" is used, Premix MEGAMIX GOST 1% for fish is used as a premix, sunflower oil is used as vegetable oil, with the following ratio of the initial components per 100 g of the finished product, g:

Fish flour 45 Blood meal 5 Protein concentrate "Agro-Matic" 15 Wheat flour eighteen Fodder yeast 9

Sunflower oil 7

Premix MEGAMIX GOST 1% for fish one

at the rate of feeding the sturgeon per day in the amount of 2% of the body weight, with a frequency of manual feeding 5 times a day (RF patent No. RU 2733136 C1, published 09/29/2020).

The disadvantages of the known formulations include the use of fishmeal, which is often not stable in terms of protein level, depending on the quality of raw materials, as well as the high cost of this component.

The task is to expand the range of domestic production feeds for growing trout.

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

The technical result is achieved with a food product consisting of a fish component, protein concentrate "Agro-Matic", wheat flour and a premix for fish, which additionally contains soybean meal and corn gluten, fish oil is used as a fish component, as a premix, a premix is used for fish, with the following ratio of components per 100 g of finished product, g:

Soybean meal 28 Corn gluten 10 Fish fat 14 Protein concentrate "Agro-Matic" 28 Wheat flour 17 Premix for fish 3

at the rate of trout feeding per day in the amount of 1.3% of body weight, with a frequency of manual feeding 5 times a day.

Protein concentrate "Agro-Matic" consists of modern low-alkaloid white lupine beans flour (crushed in several steps in special crushers), as well as poultry meat and bone meal.

The fish premix contains vitamins: A, D3, E, K3, 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.

For the preparation of feed for 1000 g, soybean meal was used - 280 g, corn gluten - 100 g, fish oil - 140 g, protein concentrate "Agro-Matic" - 280 g, wheat flour - 170 g, premix for fish - 30 g.

All the ground components of the compound feed were sieved and a mixture of dry components was prepared. Protein concentrate "Agro-Matic" was added to the resulting mixture, thoroughly mixed.

Experimental work was carried out in the conditions of the Problem Research Laboratory "Breeding of valuable sturgeon breeds" of the Volgograd State Agrarian University. 1 control and 2 experimental groups of individuals of rainbow trout 6 months old were used as objects of research. The initial weight of the experimental individuals was 110 g.

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

Analysis and generalization of experimental data obtained during research to assess the effectiveness of the use of protein components of domestic production in compound feed for trout, allowed us to draw the following practical and theoretical conclusions.

As a result of the experiment, the best results in terms of absolute gain in live weight were obtained by individuals receiving feed containing protein concentrate; they exceeded their peers from the control group by 9.6% and 11.4%, respectively. In terms of the absolute increase in body length, individuals who received feed containing protein concentrate exceeded their counterparts from the control group by 10.2% and 23.3%.

The highest average daily gain was also recorded in individuals who received feed containing protein concentrate, according to this indicator, they dominate over their control peers by 9.5 and 14.3%, respectively. The best indicators in terms of the coefficient of nutritional status were also observed in animals of the 3-experimental group, they exceeded the analogs from the control and 2-experimental groups.

Thus, the declared commercial food for trout provides an increase in the absolute, average daily, monthly gain and the coefficient of nutritional status.
