Description

Technical Field

[0001] The invention belongs to the technical field of energy supplements, and in particular relates to an energy brick used for energy supplementation of sows during lactation period. Background Art

[0002] As people's living standards improve, the demand for livestock products continues to increase, and the breeding industry is developing in the direction of scale and standardization. However, the key to the development of the pig farming industry is the low production capacity of sows. In the lactation stage, the sows' milk production is insufficient, resulting in less milk intake and malnutrition of piglets. They are prone to diarrhea and death during the weaning period, resulting in a small number of pigs and a slow production speed. To increase the milk production of breeding pigs, it is necessary to provide lactating sows with sufficient nutrition.

[0003] The most notable feature of lactating sows (sows from the beginning of parturition to the end of weaning) is lactation. Many physiological changes occur around lactation, and the metabolism of lactation is quite vigorous, and the burden on various organs is very heavy; the sows are kept in a certain body condition to achieve the purpose of timely estrus and mating after weaning. Traditional lactating sow compound feed is mainly composed of high-quality protein feed such as soybean meal to improve the quality of compound feed, and a large amount of antibiotics, chemical synthetic drugs and heavy metals and other feed additives are added to achieve the effect of antibacterial and growth promotion. Due to the tight resources of high-quality protein feed such as soybean meal, the price of traditional lactating sow compound feed is high, and the efficiency of lactating sow breeding is low; the long-term use of antibiotics, chemical synthetic drugs and heavy metals in lactating sow feed has continuously enhanced the drug resistance of pathogens, thereby leading to the continuous increase in the effective addition of antibiotics, chemical synthetic drugs and heavy metals in feed, resulting in low immunity of lactating sows and suckling piglets, seriously affecting the production performance of lactating sows and suckling piglets. At the same time, the large-scale use of feed additives such as antibiotics, chemical synthetic drugs and heavy metals also causes serious pollution to the environment and directly threatens human health. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides an energy brick for energy supplementation of sows during lactation period, so as to solve the technical problems that the existing sow lactation feed has poor effect in promoting lactation and uses a large amount of antibiotics.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is to provide an energy brick for energy supplementation of sows during lactation, comprising the following components in parts by weight: 3-5 parts of oil, 15-25 parts of carbohydrates, 5-10 parts of protein raw materials, 0.5-2 parts of amino acids, 1-3 parts of element supplements, 1-3 parts of vitamins and 10-20 parts of additives; The additive is prepared by the following steps: S1: Mix fresh Eucommia ulmoides leaves and fresh barley straw in a mass ratio of 1:3-5, and then pound the mixture into slurry; S2: Grind the fenugreek seeds into powder, then mix the fenugreek seed powder with the slurry in a mass ratio of 1:1-3, and then mix the mixture with water in a solid-liquid ratio of 1 g:5-8 mL to obtain a base material; S3: Add 30-40% of the mass of sodium chloride to the base material, mix well and let stand for 5-8 hours.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the energy brick used for energy supplementation of sows during lactation period comprises the following components in parts by weight: 4 parts of oils and fats, 18 parts of carbohydrates, 8 parts of protein raw materials, 1 part of amino acids, 2 parts of element supplements, 2 parts of vitamins and 15 parts of additives.

[0008] Furthermore, the oil is prepared by mixing soybean oil, rapeseed oil and lard in a mass ratio of 1~3:1~3:3~5.

[0009] Furthermore, the carbohydrate is at least one of corn flour, wheat flour, highland barley flour and wheat bran.

[0010] Furthermore, the protein raw material is at least one of soybean meal, fish meal and soybean meal.

[0011] Furthermore, the amino acid is lysine and / or methionine.

[0012] Furthermore, the element supplement is prepared by mixing shell powder, bone powder, ammonium ferric citrate and selenomethionine in a mass ratio of 5:3:2:1.

[0013] Further, vitamins include vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2 and vitamin C.

[0014] Furthermore, the mass ratio of vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2 and vitamin C is 1~3:1~3:0.5~2:0.1~0.5:0.1~0.5:1~3.

[0015] Furthermore, the energy brick for energy supplementation during sow lactation is prepared by the following steps: (1) Evenly mixing the formulated amounts of fats, carbohydrates, protein raw materials, amino acids, element supplements, vitamins and additives to obtain a mixed material; (2) The mixture is placed in a mold, extruded at a pressure 5 times the atmospheric pressure, and then cured at room temperature for 2 to 4 days.

[0016] The beneficial effects of the present invention are:1. The energy bricks used for energy supplementation during the lactation period of sows in the present invention include components such as oils, carbohydrates, protein raw materials, amino acids, element supplements, vitamins and additives. Among them, oils can not only improve the palatability of licking bricks, but also have high energy and can provide sufficient energy supply for sows; at the same time, oils can play a certain adhesive role and can promote the close combination of other raw materials, thereby improving the formability and stability of energy bricks. Carbohydrates can stimulate the secretion of insulin in sows, and insulin is one of the important hormones that promote mammary gland development and lactation. The energy bricks in the present invention use carbohydrates as the main component and can effectively promote milk secretion; in addition, carbohydrates can also enhance the disease resistance of sows by providing energy and regulating the function of immune cells, which helps to reduce the problem of decreased milk production and decreased milk quality caused by diseases in sows during lactation. Protein is an important component of sow mammary tissue and milk. The protein raw materials in the energy brick of the present invention can provide sows with sufficient protein supply, which can effectively ensure the continuous and efficient lactation of sows. In addition, protein intake helps the development and repair of sow mammary tissue, thereby improving the secretion capacity of mammary cells, which can not only increase the secretion of milk, but also improve the nutritional content and quality of milk. The amino acids in the energy brick can regulate the amino acid metabolism and energy metabolism in the sow, thereby improving the energy utilization rate and nutrient conversion rate, which helps to reduce the energy consumption and nutrient waste of the sow, so that it can better convert nutrients into milk to meet the growth needs of piglets. In addition, amino acids are also important molecules for regulating immune function. Adding amino acids to the energy brick can provide the amino acids necessary for the synthesis of immunoglobulins required by the body, thereby enhancing the immune function of the sow, which helps to reduce the incidence of diseases in sows, improve their health level, and thus ensure the stable performance of lactation performance. The element supplements in the energy brick can supplement calcium, phosphorus, iron, selenium and other elements for sows. Calcium and phosphorus are important components of milk. Sows have a greater demand for these two minerals during lactation. The energy brick can effectively meet the sow's needs for these two elements, thereby ensuring the secretion of milk. In addition, calcium is also involved in the contraction of the mammary myoepithelium, which is a necessary process for sows to let out milk. Adding calcium supplements can optimize this process, thereby improving the lactation efficiency of sows. Iron supplements can alleviate the iron deficiency of sows, increase the body's metabolic rate, and thus improve feed utilization. Iron is an important element for synthesizing hemoglobin and has an important influence on the immune function of sows. Adding iron supplements can enhance the immunity of sows and reduce the occurrence of diseases, which is beneficial to the lactation performance of sows. Selenium is one of the essential trace elements in the animal body, which has antioxidant, anti-stress and immunity-enhancing effects. Selenium supplements can provide sufficient selenium, which can effectively prevent problems such as sow lactation disorders.The vitamins in the energy brick can provide sows with vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2 and vitamin C. Vitamin A is a nutrient necessary for the development of sows' mammary glands, which helps the normal growth and differentiation of mammary tissue, thereby increasing the sow's milk secretion; vitamin D can promote the sow's absorption of calcium, phosphorus and other elements in element supplements, thereby ensuring the amount and quality of milk secretion; vitamin E, as an antioxidant, can protect the sow's mammary tissue from damage by oxidative stress and maintain its normal function, and vitamin E can promote the secretion of sows' thyroid, adrenocorticotropic hormone and gonadotropin, thereby indirectly promoting lactation; B vitamins play an important role in the sow's energy metabolism process, helping to improve energy utilization and nutrient conversion rate; vitamin C helps to enhance the sow's immunity and reduce the occurrence of diseases, which is beneficial to the sow's lactation performance. The additive in the energy brick of the present invention is prepared from eucommia leaves, barley grass, fenugreek seeds and sodium chloride. During the preparation, the eucommia leaves and barley grass are first crushed, which is conducive to the overflow of effective ingredients in the eucommia leaves and barley grass. The subsequent addition of sodium chloride can adjust the cell osmotic pressure and further promote the overflow and enrichment of effective ingredients. The addition of sodium chloride can not only stimulate the taste buds of sows, increase appetite, and improve the digestion and absorption rate of feed, but also stimulate the sows to drink water, thereby increasing the sows' water intake, helping to maintain the balance of water in the sows' bodies, reducing dehydration caused by lactation, and thus facilitating the smooth progress of the lactation process. The main components of eucommia leaves include chlorogenic acid, eucommia flavonoids and eucommia polysaccharides, etc. These components can stimulate the hypothalamus-pituitary-gonad axis of sows, promote the secretion of related hormones, thereby increasing the sows' lactation, and at the same time It can also improve the intestinal health of sows together with the crude fiber in barley grass, making sows in a better health state and conducive to lactation; barley grass is rich in vitamins, minerals and dietary fiber, the nutrients in which can provide comprehensive nutritional support for sows, and dietary fiber helps to promote intestinal peristalsis of sows, improve intestinal health, and increase the absorption and utilization rate of nutrients, which is conducive to lactation. The digestion of dietary fiber will make sows thirsty, thereby promoting sows to drink water, and then promote sows to secrete more milk; fenugreek seeds contain a large amount of saponins, which can reduce the abundance of Escherichia coli in the sow's intestines after sows eat them, improve the intestinal environment, and increase the absorption and utilization rate of nutrients. In addition, fenugreek seeds can also increase the serum immunoglobulin G (IgG) content of sows on the day of farrowing and during lactation, thereby enhancing the body's immune function.

[0017] 2. The energy bricks used for energy supplementation during the lactation period of sows in the present invention do not contain antibiotics and chemical synthetic drugs, and will not have adverse effects on the growth of sows, nor will they indirectly affect human health.

[0018] 3. The energy bricks used for energy supplementation during the lactation period of sows in the present invention are presented in the form of bricks, which are not only convenient for storage and transportation, but also sows mainly eat in the form of licking, which can slow down the sow's eating speed, and can effectively ensure the continuous supply of energy while reducing the number of feeding times.
