Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention divides the feed for breeding boars into feed for breeding boars, feed for replacement gilts, feed for pregnant sows and feed for lactating sows according to the nutritional requirements of the boars at different breeding stages.
The functions of the components involved in the feed for breeding pigs provided by the present invention are described below.
Corn, as an energy feed for pig feed, is known as the "energy king" and accounts for the largest proportion in the feed. Although corn has the main function of providing energy, the protein provided by the corn accounts for about 1/4 of the total protein in the feed, and therefore, the corn is also a very high-quality protein resource.
The peeled soybean meal is produced by drying, heating, breaking, winnowing, leaching and other processes, and has higher protein content and amino acid content than the peeled soybean meal. The soybean meal is easy to digest and absorb, can effectively stimulate the proliferation of beneficial bacteria in intestinal tracts, regulates the structure of microecological flora in bodies, and increases the decomposition, synthesis, absorption and utilization of feed nutrients by digestive tracts. The soybean meal contains crude protein up to 30-50%, is one of main protein feeds for animals, is main plant protein in the feed, and has the advantages of high protein content, balanced amino acid and good palatability.
Fish meal is a high-protein feed raw material which is prepared by using one or more fishes as raw materials and carrying out deoiling, dehydration and crushing processing. Fish meal contains high fat and is a high-energy feed. Fish meal is a good source of minerals, has high contents of calcium and phosphorus and proper proportion, and all phosphorus can be utilized. Meanwhile, the feed additive has high digestibility and good palatability, and can improve the feed intake of livestock and poultry and improve the production performance.
The puffed soybean is a feed product of whole soybean after puffing, retains the nutrient components of the soybean, removes the anti-nutritional factors of the soybean, and has strong oil fragrance, high nutritional value and good palatability.
The seaweed powder is prepared by finely processing marine natural seaweed serving as a main material and a small amount of marine microalgae serving as an auxiliary material. The seaweed powder is rich in amino acids and proteins, and also contains seaweed polysaccharide, mannitol, amino acids, proteins, vitamins, and trace elements such as potassium, iron, calcium, phosphorus, iodine, selenium, and cobalt. The seaweed meal is added into the feed, so that the growth and development of piglets can be promoted, and the production performance of the pigs can be improved.
The beet pulp is a byproduct of sugar production, and is the residue after sugar solution is extracted by soaking and squeezing beet tuberous roots and tubers, so that a great amount of water-insoluble substances exist in the residue, and especially crude fibers are completely reserved. The beet pulp is a good succulent feed for livestock, has lactation promoting effect on sow, contains soluble nitrogen-free substances as main ingredients, and has little protein and fat, extremely high calcium content, little phosphorus content, strong palatability and more crude fiber content.
The puffed flaxseed is obtained by puffing and extruding, removes anti-nutritional factors in the flaxseed, has puffed fragrance, is loose in particles, and has good palatability when used as a feed. Flaxseed, also known as linseed, contains mainly oil and proteins, and also contains a certain amount of flaxseed gum and lignans. The linseed gum is also a good dietary fiber, can promote digestion and absorption of pigs, and can prevent and treat intestinal diseases of the pigs.
The wood fiber is organic flocculent fiber substance obtained by chemical treatment and mechanical processing of natural renewable wood. Wood fiber is an insoluble fiber that helps maintain the normal structure and function of the porcine gastrointestinal tract.
Alfalfa meal is powder prepared from tender stems and leaves of Melissitus ruthenicus or Melissitus ruthenicus of Leguminosae. The alfalfa contains a proper amount of crude fiber, can promote the large intestine peristalsis of pigs, improve the carcass quality, help the excretion of excrement and toxin, prevent and treat constipation and intestinal cancer, and improve the reproductive performance of the pigs. After eating, the pig has strong physique and bright hair, and has direct promotion effect on improving the protein content of livestock. The addition of alfalfa meal at an appropriate level in the pig feed can improve the productivity, reproductive performance and carcass quality of pigs.
Soybean oil is mainly composed of 5 kinds of fatty acids such as palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid. Generally, linoleic acid content is highest, accounting for over 50-55% of fatty acid content. Linoleic acid is essential fatty acid required by sows, and soybean oil added into the feed for the sows can improve the reproductive capacity of the sows.
Fish oil is a by-product of fish meal processing, and is obtained by steaming, squeezing and separating fish and its waste. The main components of the fish oil are: triglyceride, phosphoglycerol ether, lipoid, fat-soluble vitamin, protein degradation product, etc. After being absorbed by the pigs, the fish oil is converted into energy for the activity consumption of the pigs, thereby improving the available energy in the feed, reducing part of protein consumed as energy, and achieving the purposes of saving protein, improving the feed energy, reducing the feed cost and promoting the growth and development of the pigs. The fish oil not only provides n-3 long-chain polyunsaturated fatty acid essential for animals, but also can be used as a carrier of fat-soluble vitamin A, D, carotenoid and the like to promote the absorption and utilization of the vitamin by fat-soluble substances.
The coconut oil contains medium-short chain fatty acid with a high proportion of more than 80 percent, and can remarkably reduce the number of ciliates and methanogens in the rumen of ruminants in the aspect of animal feeding, but has no remarkable influence on the growth of the animals, the total bacteria number, the cellulose decomposition fungi number, the pH value and the number of protozoa in the rumen.
Calcium hydrogen phosphate, stone powder and salt all belong to mineral feeds, provide mineral macroelements necessary for animal growth, and play an indispensable role in animal growth.
Calcium hydrogen phosphate is used as a calcium and phosphorus supplement and is referred to herein as feed grade calcium hydrogen phosphate. The phosphorus-calcium ratio of calcium hydrogen phosphate is the closest to that of animal bone, and the calcium hydrogen phosphate can be completely dissolved in animal gastric acid, and is a good feed mineral additive. Calcium hydrogen phosphate can accelerate the growth and development of pigs and quickly increase weight; can improve the hybridization rate and the survival rate of the pigs.
The stone powder is an animal calcium supplement, the main component is calcium carbonate, and the calcium content is more than 38%. The stone powder is mainly used for bone growth and blood calcium maintenance. The addition of the stone powder can not only improve the quality and the utilization rate of the feed, but also greatly reduce the cost of the raw materials.
The chemical component of the salt is mainly sodium chloride, is an important mineral substance in the feed, and is an essential substance for maintaining life activities. Sodium can maintain acid-base balance of blood and tissue fluid, regulate stability of normal osmotic pressure, stimulate secretion of saliva, and promote appetite of pig. Sodium can promote the synthesis of organic matters such as fat, protein and the like in the metabolic process; can keep digestive juice alkaline in intestinal tract, activate amylase, keep gastric juice acidic, and has antibacterial effect. The lack of salt or insufficient salt content in the feed can cause inappetence, digestive disorder and pica of pigs.
The additive premix is an intermediate compound feed product prepared by uniformly mixing a plurality of trace components (including additives such as various trace elements, vitamins, amino acids and substances with certain special effects) and a carrier according to the required proportion.
It should be noted that the beneficial effects of the feed for breeding pigs at each stage provided by the invention are determined by the specific raw material components and the mixture ratio thereof, and if the components and the mixture ratio thereof are not coordinated with each other, the beneficial effects brought by the single component are probably reduced or even eliminated by other components, so that the feed cannot play a comprehensive role. According to the invention, through a large number of researches and repeated verifications, the optimal combination and proportion of the boar and sow feed at each stage are obtained, so that a plurality of components are integrated and coordinated with each other to generate positive synergistic effect, the finally prepared breeding pig feed is more reasonable in formula, and the nutritional requirements of boars at different breeding stages can be met.
