Description

[0001] The invention relates to agriculture and can be used in feeding young chickens from 15 weeks to 2-5% productivity.

[0002] Feeding poultry should ensure their physiological needs for metabolic energy, nutrients, and biologically active substances are met to maintain health and increase productivity. Highly energy-dense feeds and concentrates should be added to the bird's diet. Feeding a homogeneous, balanced feed mixture is essential. The advantage of feeding birds a homogeneous, balanced feed mixture is that it reduces feed consumption by 20-30% and reduces labor costs by 1.2-1.5 times.

[0003] The poultry diet must contain a significant amount of protein, carbohydrates, fat, vitamins, and minerals. The nutritional value of the feed can be increased by adding various feed additives. Deficiencies in micro- and macronutrients significantly impact poultry productivity. Fish waste is useful for the production of various protein supplements. Fish waste, in turn, includes bones, heads, and trimmings. The production process for supplements and fish waste involves several stages, including cooking, drying, and grinding the raw materials. This process results in a finished product called fishmeal.A bird's productivity is 40-50% dependent on energy intake, and a lack of energy is often the most likely cause of increased feed consumption and low productivity. For more cost-effective poultry production, it's advisable to use waste from the fish and seafood industries, as well as plant-based raw materials, as they are less expensive to transport and less expensive.

[0004] A compound feed for broiler chickens is known, containing wheat, corn, fish meal, corn gluten, sunflower oil, table salt, a vitamin premix, characterized in that it additionally contains wheat bran, lupine, meat and bone meal, DL-methionine 99%, L-threonine 98.5%, lysine monohydrochloride 98%, L-lysine sulfate, L-arginine 98.5%, monocalcium phosphate, bischofite, potassium carbonate (potash), while sunflower meal is used as meal, and limestone grits are used as limestone, with the following ratio of components, %:

[0005] Wheat 45,0-57,0 Corn 13,7-16,5 Wheat bran 2,6-5,0 Lupine 5,0-7,5 Sunflower meal 8,5-12 Corn gluten 2,0-4,8 Fish meal 1,5-2,5 Meat and bone meal 3,5-4,5 DL-methionine 99% 0,13-0,14 L-threonine 98.5% 0,04-0,1 Lysine monochlorohydrate 98% 0,1-0,3 L-lysine sulfate 0,2-0,4 L-arginine 98.5% 0,02-0,04 Table salt 0,05-0,1 Sunflower oil 1,3-2,0 Monocalcium phosphate 0,1-0,3 Bischofite 0,03-0,03 Potassium carbonate (potash) 0,02-0,1 Limestone grits 0,4-0,5 Vitamin premix Rest

[0006] moreover, the compound feed is fed from the age of one day to 37 days in accordance with the standard indicators for growing broiler chickens of the Ross 308 cross (Patent of the Russian Federation No. 2 802 227, published on August 23, 2023).

[0007] It should be noted that the well-known recipe for compound feed was developed for meat-producing chickens and cannot be used for feeding young egg-producing chickens due to different requirements for the nutritional value of compound feeds.

[0008] A feed for young egg-laying hens is known, including wheat, barley, sunflower cake, soybean meal, fish meal, vegetable oil, corn, bran, chalk, salt, a premix, characterized in that it additionally includes a complex of mineral substances: zinc sulfate, sodium selenite and potassium iodide in the following ratio of components, wt. %:

[0009] Wheat 38 Barley 26 Sunflower cake 3 Soybean meal 5 Fish meal 7 Vegetable fat 1,1 Corn 10 Bran 6,991054-6,96582 Chalk 1,5 Salt 0,4 Premix 1 Zinc sulfate 0,0089-0,034 Sodium selenite 0,000022-0,000088

[0010] Potassium iodide 0.000024-0.000092

[0011] (Patent of the Russian Federation No. 2383208, published on March 10, 2010).

[0012] The disadvantage of this compound feed is that this compound feed was fed to young animals from the hatching period to 14 weeks of age, which currently does not comply with the recommendations for feeding agricultural poultry (Methodological guide to feeding agricultural poultry / Egorov I.A.; Manukyan V.A.; Lenkova T.N.; Egorova T.A. et al. - Sergiev Posad: VNITIP, 2021. - 359 p.). According to the above recommendations, a 3-phase feeding of replacement young hens of the egg-laying direction is used (phase 1 - from 1 to 7 weeks of growing, phase 2 - from 8 to 14 weeks of growing and phase 3 - 15 weeks up to 2.5% productivity).

[0013] The prototype is a compound feed for laying hens containing wheat, barley, corn, sunflower cake, fish meal, chickpeas, a calcium supplement, tricalcium phosphate, a premix characterized in that it additionally contains soybean meal, sunflower oil, wherein the wheat used is spring crushed wheat, the barley used is spring hulled crushed barley, the corn used is yellow crushed corn, the chickpeas used are feed chickpeas of the Privo 1 variety, and shell flour is used as a calcium supplement, with the following ratio of the original components, %:

[0014] Crushed yellow corn 5,0-9,0 Crushed spring wheat 32,0-35,0 Crushed spring barley 24,0-29,0 Sunflower cake 3,6-3,7 Forage chickpea variety Privo 1 11,2-11,3 Soybean meal 0,0-3,0 Sunflower oil 1,9-2,0 Fish meal 5,0-6,0 Tricalcium phosphate 1,0-2,0 Shell flour 6,0-7,0

[0015] Premix, the rest of the compound feed is fed during the egg-laying period in the amount of 115 g per head per day (Patent of the Russian Federation No. 2678754, published on January 31, 2019).

[0016] The disadvantage of this compound feed is that it is intended for feeding to adult laying hens, the nutritional value of which has different requirements compared to pullets at the beginning of the egg-laying period.

[0017] The problem that this invention is aimed at solving is obtaining a balanced compound feed for young chickens from 15 weeks up to 2-5% productivity using the Volgafish fish concentrate.

[0018] Technical result - increased livestock survival, live weight, herd uniformity, commercial yield and a decrease in feed consumption per unit of live weight gain of young chickens from 15 weeks to 2-5% of productivity.

[0019] The technical result is achieved in that the compound feed for young chickens contains corn, wheat, sunflower cake, soybean meal, sunflower oil, fish meal, phosphorus-calcium additive, natural calcium additive and premix, additionally contains wheat bran, full-fat soybeans, sunflower meal, Volgafish fish concentrate, meat and bone meal, L-lysine sulfate L-premiUM+, DL-methionine, table salt, sodium sulfate anhydrous, while monocalcium phosphate is used as a phosphorus-calcium additive, limestone grits are used as a natural calcium additive, with the following ratio of components, %:

[0020] Wheat 52,00 Corn 9,87 Wheat bran 4,00 Full-fat soybeans 3,63 Soybean meal 2,05 Sunflower meal 5,16 Sunflower cake 6,83 Fish meal 2,00 Fish concentrate "Volgafish" 5,00 Meat and bone meal 2,60 L-lysine sulfate L-premiUM+ 0,21 DL-methionine 0,10 Sunflower oil 0,53 Table salt 0,30 Monocalcium phosphate 0,70 Sodium sulfate anhydrous 0,08 Limestone grits 3,94 Premix 1,00

[0021] The essential distinguishing features of the declared compound feed are its qualitative and quantitative composition, its dosage per head per day for young chickens from 15 weeks to 2-5% of productivity.

[0022] The stated quantitative and qualitative characteristics are optimal.

[0023] A decrease or increase in the specified quantitative interval entails a deterioration in the characteristics of the declared compound feed, and, therefore, will not allow the declared technical result to be achieved.

[0024] The main goal of zootechnical control in the rearing of egg-laying pullets is to achieve standard live weight at the appropriate age and uniformity of the herd, especially at the beginning of egg laying.

[0025] The nutritional value of the declared compound feed is given in Table 1.

[0026] Examples of specific implementation. To confirm the effectiveness of the proposed feed, a trial was conducted at the Volzhskaya Poultry Farm in the Sredneakhtubinsky District of the Volgograd Region. The trial included pullets of the Hisex Brown cross from 15 weeks of age to 2-5% productivity. The test pullets were housed in battery cages. The trial lasted five weeks. Birds were selected using the analog method, taking into account their cross, age, and development. Each group contained 155 birds. Housing conditions, feeding and watering space, and microclimate parameters were identical and corresponded to the cross's recommendations.

[0028] The daily feed consumption of young chickens according to the standard indicators of the Hisex Brown cross is presented in Table 2.

[0029] Throughout the experiment, flock survival, live weight, and feed consumption were monitored. The poultry performance indicators are presented in Table 3.

[0030] The flock uniformity at the end of the experiment was 86.00%. The bird survival rate throughout the experiment was high and amounted to 100.00%.

[0031] The live weight of the bird at 15 weeks was 1217.50 g, at 19 weeks - 1595.00 g. The average feed consumption per head was 2786 g.

[0032] The business yield of the pullets was 84.03%.

[0033] Thus, the declared compound feed allows to increase the survivability of livestock, live weight, herd uniformity, the productive yield of pullets and to reduce the cost of compound feed per 1 kg of live weight gain from the 15th week to 2-5% of productivity.
