Description
High palatability creep feeding material for piglets and preparation method thereof
The invention relates to the technical field of feed, in particular to a high palatability creep feeding material for piglets and a preparation method thereof. BACKGROUND
Creep feeding material refers to the high-grade compound feed used for piglets from 7 days old to 1-2 weeks after weaning. Because of the weak digestive physiological function, imperfect digestive tract structure and low digestive enzyme secretion activity, piglets can not digest solid feed well; Moreover, piglets are sensitive to smell and taste, and the number of taste buds on the mucous membrane of pig tongue is about 9000, which is 1.5 times of that of human beings. Therefore, piglets often have the phenomenon of "picky eaters" and "refusing to eat", so it is of great significance to teach the palatability of
trough materials for piglets to attract food and improve feed intake during lactation. During the weaning period, piglets are prone to weaning stress syndrome, which is characterized by atrophy and degeneration of small intestinal villi, which takes 10-14 days to recover; The intestinal microflora changed, four days after weaning, the intestinal Escherichiacoli proliferated by 20%, and the number of lactic acid bacteria decreased by %. Gastric acid recovered to the level before weaning 10 days after weaning. The activity of pancreatic enzyme in intestinal tract decreased in different degrees, and the activity of trypsin and pancreatic amylase increased to that before weaning 4 days and 10 days after weaning respectively. This indicates that the feed intake of piglets is easily affected within 1 week or 10 days after weaning, and teaching the palatability of trough materials is particularly critical to the feed intake of piglets in weaning period and the performance of preventing fat loss. At present, the invention and research of the creep feeding material for piglets show that the palatability of the creep feeding material is mainly related to the digestibility of the raw materials and the attractant ingredients. The energy feed raw materials in the existing creep feeding materials are mainly partially puffed or expanded grains, lacking or not having small molecular carbohydrates, and the antigen content of P -conglutin in the plant protein feed raw materials, especially the processed products of beans, is high, which still can not be well digested and absorbed by piglets, resulting in nutritional indigestion, diarrhea, etc., and feedback inhibits piglets from eating. In addition, the inherent bad smell of various raw materials in creep feeding materials and the unpleasant taste produced during processing and storage will reduce the palatability of piglets, which is often covered by taste improvers such as sweeteners and flavoring agents in production practice. Studies have shown that piglets have imprinting on olfaction. The piglet has a good sense of smell,Before birth, the maternal smell has been transmitted to the fetal pig. After birth, the piglet can use the sense of smell to identify the position of the sow nipple. People's studies have also shown that garlic smell molecules can be detected in maternal amniotic fluid when mothers eat food with garlic smell, while the fetus absorbs amniotic fluid through placenta, and the molecules with garlic smell enter the fetus. Further study suggested that a- Iacid glycoprotein (GAP) and odor binding protein (OBP) in amniotic fluid of sows were related to odor transport, which confirmed that odor molecules were transmitted to fetal pigs through amniotic fluid. The preference of piglets to teach trough materials depends not only on the smell and taste of food, but also on the experience of eating this kind of food. When piglets come into contact with creep feeding materials after birth, the sense of smell can distinguish the peculiar smell and taste components. It is assumed that if the creep feeding materials contain flavors similar to the amniotic fluid environment in which fetal pigs live and develop, the sucking and palatability of creep feeding materials will be greatly improved because the brains of piglets have a certain memory of the amniotic fluid smell. Amniotic fluid is filled in amniotic cavity, which is mainly composed of dialysate from maternal serum entering amniotic cavity through placenta, water in fetus, exudate of small molecules passing through unborn fetal skin, and urine discharged from fetus. It is colorless and transparent alkaline liquid, of which more than 90% is water, and it also contains minerals, urea, uric acid, creatinine, fetal fat and fetal epithelial cells, etc., thus forming special amniotic fluid taste. There is no report on the improvement of palatability of piglets to creep feeding materials by amniotic fluid flavor, and there is little research on the effect of coating trace elements with low gastric mucosa damage on palatability of creep feeding materials.
The invention aims to provide a high palatability piglet creep feeding material and a preparation method thereof. Macromolecular carbohydrates and plant protein feed raw materials used in the invention are all cured or fermented, the trace element compound premix used in the invention is coated and processed, and then the special amniotic fluid flavor nutrient is developed by simulating amniotic fluid, and then a fresh, non-cross contamination and unique amniotic fluid flavor high palatability creep feeding material is produced through a short-path and low-residue production process, which is easy for piglets to eat, fast in feeding trough and high in feed intake, especially promotes the feeding of piglets 3-10 days after weaning.

Upon detection, the main conventional nutrients and amino acid contents of the high palatability piglet trough material prepared by the invention are as follows: digestible energy (DE)3303-3506kcal/kg, crude protein (CP) 17.8-19.9%, crude ash (CA) 4.94 5.60%, crude fiber (CF) 1.21-1.90%, crude protein (CP) 17.8-19.9% 0.47-0.66% NaCl, 1.23-1.35% Lys, 0.67-0.82% TSAA, 0.80-0.90% Thr and 0.23-0.26% Trp.

In the invention, "%"is the mass percentage. Compared with the prior art, the invention has the following beneficial effects: (1) In the present invention, the macromolecular carbohydrate corn and broken rice are expanded by dry method at 130°C, and the gelatinization degree of a -starch reaches over 75%, which is more than doubled compared with that without expansion, and the inherent flavor of the grain expanded by dry method is easier to overflow; With flour and whey powder, the cereal feed raw materials in the creep feeding material are diversified; In addition, as one of carbohydrate feed raw materials, the intermediate product of starch hydrolysis, small molecular dextrin, does not need to rely on amylase for re-degradation, and has high digestion and absorption rate, while dextrin is rarely added to the teaching materials in the market. The carbohydrate has high maturity, good digestibility, strong intrinsic flavor of grains and many small molecular intermediates, which improves the palatability of the teaching materials. (2) In the invention, dry puffed soybeans (above 130°C) are selected, and the inherent bean fishy smell of soybeans is rich; The fermented soybean meal with acid soluble protein > 8% and organic acid >2% is preferred,The fermented soybean meal has good acid flavor and high content of small peptide, which is helpful to promote piglets to eat and prevent allergic diarrhea caused by soybean meal antigen. (3) Amniotic fluid and fetal fat contain sodium salt, potassium salt, urea, cholesterol, triglyceride, monoacylglycerol, phospholipid, ceramide, protease, cytoskeleton protein, immune protein, antibacterial peptide, defense protein lysozyme, lactoferrin, serum protein, etc. These complex components and water constitute the unique smell of amniotic fluid. The amniotic fluid imprinting nutrient contains buffer sodium salt and potassium salt, fats with various molecular structures, plasma protein powder with high serum protein content, wheat hydrolyzed protein with high glutamine content, whole egg powder with high cholesterol, egg yolk globular protein powder, lysozyme, lactoferrin and other nutrients and active components, and has amniotic fluid flavor characteristics. The amniotic fluid-flavored piglet creep feeding material can awaken the taste memory of piglets during fetal contact, and improve the palatability of suckling and weaning period piglets through imprinting transmission, with unique and remarkable efficacy. (4) The invention designs a coating trace element composite premix with low additive amount, in which a plurality of monomer organic trace elements are selected, and meanwhile, organic macromolecular potato starch, calcium stearate and hydrogenated fat are used for relatively tight coating, so that the damage caused by direct contact of trace elements and heavy metals contained therein with gastric mucosa is effectively reduced. Trace elements and heavy metals have less bad smell such as metal smell, which not only protects stomach and intestines, increases absorption, but also improves palatability of teaching materials. (5) In the present invention, only two kinds of raw materials, namely, mature and digestible carbohydrate, mature and zymolytic protein, are delivered to the batching bin and mixer through pipelines, and all other raw materials need to be directly put into the mixer, so that the production process path is shorter, the pollution is less, functional components such as a small proportion of raw materials have no residue, and the prepared piglet creep feeding material is fresh and stable in quality. (6) 28-day-old piglets are easy to begin creep feeding before weaning; The average feed intake of 28-day-old was 60, 220, and 320g/ head on the first, second, and third days after weaning, and the total average feed intake reached 600g/ head in the first three days after weaning, which was 18-25% higher than that of common teaching materials. Amniotic fluid flavor trough material is a unique high palatability trough material, which has the advantages of quick eating, large feed intake, easy digestion, good absorption, low mucosal damage and low toxicity due to low trace elements coating.
