Description

Efficient nutrition feeding method for commercial pigs

Technical Field

The invention relates to the technical field of breeding industry, in particular to a high-efficiency nutrition feeding method for commercial pigs.

Background

In the pig raising production, along with the continuous improvement of pig breeds, the farrowing rate and the growth speed are always improved, but the feed conversion ratio is not obviously improved, the slaughter weight is developed from 200 jin to over 240 jin today, and even the slaughter weight is larger. The pig raising and consumption habits have changed greatly, so the original material using habits are not reasonable enough, and the nutrition is not accurate enough.

According to the traditional pig feeding method, the growth and development of pigs are divided into three stages, namely a piglet stage (a growth period with the weight of 20-35 kg), a middle pig stage (a development period with the weight of 36-60 kg) and a big pig stage (a fattening period with the weight of more than 61-90 kg), the feeds in different stages are designed according to the nutritional requirement characteristics of the pigs in the three stages, and a linear fattening method or a front-attack rear-limit fattening method is mostly adopted in a feeding mode. However, the feed design and feeding modes aim at increasing the weight of pigs in each growth period, and emphasis is placed on the indexes such as crude protein, digestion energy and the like in the feed in each period, and meanwhile, the necessary fine management is lacked for piglet feeding for neglecting the actual problem of solving the problem of pigs in each feeding stage; the lack of necessary continuity in each feeding stage leads to stress reaction of commercial pigs in the feeding process, so that the problems of feed intake reduction, dysphoria, aggressive enhancement, growth retardation, diarrhea and the like of the fed pigs are caused, the condition seriously produces the stiff pigs, even the fed pigs die, and finally the whole economic benefit is not guaranteed, thereby causing great loss to the pig feeding production. Therefore, a commercial pig high-efficiency nutrition feeding method is urgently needed, so that the aim of helping farmers to achieve high-efficiency pig raising is fulfilled.

In the creep stage, the main nutrient substances of the piglets come from breast milk and supplementary materials, in the stage, the plasticity of digestive organs of the piglets is very large, the food of newborn piglets is mainly digested in small intestines, the intestinal glands and pancreas of the newborn piglets are completely developed, and various digestive enzymes for digesting the breast milk can be secreted, wherein, the contents of trypsin, pancreatic lipase and lactase in intestinal juice are very high, the fat and protein contained in the breast milk can be better digested, and plant proteins in the feed can be gradually adapted to the continuous development of a digestive system. Therefore, the corn and the bean pulp are selected and pretreated by adopting the puffing process, and the corn and the bean pulp are pretreated by adopting the superfine powder process, so that the palatability is improved, the intestinal digestion burden is reduced, and the diarrhea rate is reduced; in order to promote the piglet to eat, the feed intake of the piglet is improved by adding the flavor leda 39550Z; meanwhile, bacillus subtilis, lactic acid bacteria, amylase, neutral protease, 35% xylo-oligosaccharide and mannan oligosaccharide are added to regulate intestinal flora, reduce the anti-nutritional effect of non-starch polysaccharide, supplement the deficiency of endogenous digestive enzyme of piglets, promote intestinal health, and further improve the blood sugar content of piglets, so that the blood sugar content is further improved, the blood sugar is controlled to be maintained at a higher level, the risk of insufficient nutrient substance metabolism of piglets is reduced, the hormone is regulated and controlled to be raised back to a normal level, and the overall health degree of the piglets is improved. Practice proves that the daily gain of the commercial pigs reaches up to 0.5 jin/day, the feed-meat ratio is 1.14, piglets are good in food calling, diarrhea resistance and free of losing weight, the intestinal tracts are healthy, and the uniformity is good.

Meanwhile, through years of practice and practical production conditions, the feeding method is adopted to feed the Du x long x big (DLY) ternary hybrid pigs, and the weaning is determined to be carried out in the period of 21-25 days of age. The weaning day age refers to the day age of the piglets stopping sucking the breast milk and eating the feed completely, the piglets cannot eat the breast milk during weaning and have stress reaction and often have the phenomenon of no eating or little eating, thereby reducing the nutrient absorption area of the intestinal tract, consuming body fat to become thin, reducing the activity and resistance of digestive enzymes, therefore, at this stage, the first-stage conservation material provided by the invention is prepared by applying the raw materials such as whey powder, puffed soybean, fish meal and the like, meanwhile, the soybean meal raw material and the like are subjected to a superfine powder process, the connection with the creep feed raw material structure is well made, the stable transition of the weaned piglets is realized, and meanwhile, the high palatability, the high digestibility and the high-quality feed are ensured, especially increases the dosage of porket multimineral and multivitamin, simultaneously adds astragalus polysaccharide and hirudo oil, thereby improving the capability of resisting weaning stress, enhancing the immunity of the suckling pigs and reducing the use of antibiotics for farmers; practice proves that the daily gain of the commercial pigs can reach 1 jin/day, the feed-meat ratio is 1.45, no diarrhea occurs, and the intestinal tract is healthy.

The commercial pigs are 28-50 days old, two-stage conservation materials are adopted, the effective transition from high-grade raw materials to corn bean pulp type daily ration is realized through the scientific combination of the puffed soybeans and the whey powder, the daily weight of the commercial pigs is increased by 1.1 jin/day, the feed-meat ratio is 1.6, the feed intake is improved by more than 10%, the conservation materials and the piglet materials are effectively converted by linking, and the growth speed is high.

In the first stage of fattening (piglet stage), the feeding method of the invention adds 0.8% of emulsified oil powder according to complete feed, provides multiple energy sources, adds 1-1.2% of lysine, utilizes an amino acid balance model to meet the amino acid requirement of piglet growth, promotes the piglet to develop healthily, and the amino acid model of the first stage of fattening feed is as follows: lysine is taken as a base, lysine (%) is 100, methionine (%) is 30, egg + cystine (%) is 58, and threonine (%) is 60-65; meanwhile, by applying a nutrition balance theory, the ratio of the energy protein to the protein is 188.1-188.5:1, the nutrition waste is avoided, and the feed conversion ratio is reduced; furthermore, the combination of functional oligosaccharide and plant extract is used for promoting the immunity to be improved, so that the disease resistance of the piglets is improved. Practice proves that the daily weight of the commercial pigs is increased by 1.62 jin/day, the feed-meat ratio is 2.0, the commercial pigs grow fast, the skeleton is pulled open, the body shape is good, the intestinal tract is healthy, and the later-stage fattening is promoted.

In the second fattening stage (middle pig stage), the feeding method of the invention continues the nutrition basis of the piglet stage, and adopts the same amino acid level as the piglet stage, thereby stimulating the maximum growth potential; meanwhile, low-quality carriers are removed, 2.0-3.0% of fermented soybeans are added, the palatability of the pigs is improved, and the feed intake is continuously increased; furthermore, the combination of functional oligosaccharide and complex enzyme is adopted, so that the immunity and the digestibility are improved, the growth is fast, and the disease resistance is strong. The daily weight gain is 1.62 jin/day, the feed-meat ratio is 2.0, the growth speed is high, the skeleton is pulled open, the body shape is good, the intestinal tract is healthy, and the later fattening is promoted. Practice proves that the daily weight of the commercial pigs is increased by 1.85 jin/day, the feed-meat ratio is 2.6, and the pigs grow faster by applying the nutrition standard of the piglets.

In the third fattening stage (big pig stage), the feeding method of the invention selects energy raw materials such as puffed soybeans, fat powder and the like, strengthens energy nutrition and enriches energy sources; meanwhile, on the basis of high amino acid nutrition, 1.2-1.4% of lysine is added, and the addition amount of methionine is 0.36-0.42%, so that the deposition of lean meat is promoted, and the body shape is improved; the vitamin is added in a strengthening way, and simultaneously, organic trace elements such as yeast selenium and the like are used, so that the meat color is bright red. Practice proves that the daily weight gain reaches 1.92 jin/day, the feed-meat ratio is 3.24, the growth speed is high, the feed ratio is low, and the meat quality is good.

According to the feeding method, through accurate adjustment and control of commercial pigs in each stage, the breeding target that the weight of piglets is increased by more than 230 jin in 150 days after weaning and the feed-meat ratio in the whole process is 2.5:1 is achieved. The inventor finds that the regulation of blood sugar has great influence on the growth and development of commercial pigs through long-term practice research, and the maintenance of stable or higher blood sugar is beneficial to the healthy growth and development of the commercial pigs, so that nutrients such as glucose and the like are directly added, thereby improving the utilization rate of the commercial pigs to the nutrients and directly increasing the blood sugar content; meanwhile, the inventor supplements and adds various vitamins with different proportions and dosages, and the regulation and control effects among different vitamins are adopted, so that the blood sugar content is further improved, the blood sugar is controlled to be maintained at a higher level, and meanwhile, the damage of heavy metals and the like to the liver and kidney functions of commercial pigs is reduced by adding beneficial flora and vegetal polysaccharide, so that the synthesis and release of sugar by the liver are repaired and protected, and the promotion effect on the improvement of the blood sugar value is achieved;
