Problems solved by technology

At present, most of the suckling pig creep feeds on the market have problems in various aspects. For example, the long-term use of antibiotic-added suckling pig creep feeds increases the drug resistance of animals, causing bacterial flora imbalance and endogenous infection in animals; The feed is unstable and cannot be well absorbed in the suckling pig; the poor palatability of the granular feed or the whole powder product will cause the symptoms of oral ulcers in the suckling pig, and at the same time, the feed will stick to the mouth and reduce the utilization rate of the feed; The nutrient concentration of liquid feed cannot meet the growth of animals, and at the same time, it is easy to spill and waste feed; most of the creep feeds are stored for a short period of time, and the storage conditions are relatively strict, which leads to increased transportation and storage costs
[0004] In view of the above problems, the present invention provides a creep feed companion, which has good palatability, can effectively maintain the stability of the creep feed, avoid feed waste in the creep stage, effectively improve the weaning stress of suckling pigs, and solve For problems such as low feed intake, nutrient deficiency, and poor resistance of suckling pigs, quickly supplement and maintain the coordination and balance of intestinal flora, which will help the adaptation, domestication and development of sucking pig intestines, increase feed intake, and increase growth speed

[0049] The preparation method of described aliphatic polyester-amidated hyaluronic acid is:

[0050] (1) Preparation of amidated hyaluronic acid: dissolve hyaluronic acid in water, add 0.1mol L -1 After adjusting the pH to 5.5 with hydrochloric acid, add catalyst 0.6mmol L -1 1-ethyl-(3-dimethylaminopropyl)carbodiimide, 0.06mmol L -1 For N-hydroxysuccinimide, add allylamine after warm stirring for 15 minutes, and react for 4 hours to obtain amidated hyaluronic acid;

[0051] (2) Synthesis of aliphatic polyester macroinitiator: add triethylamine (0.276mmol) in the dry dichloromethane solution (15mL) of 15% (v / w) polylactic acid under nitrogen atmosphere, mass fraction, The mixture was stirred for 30 min and then cooled to 0 °C. A dichloromethane solution (8 mL) with a mass fraction of 0.3% (v / w) 2-bromoisobutyryl bromide was added dropwise to the polylactic acid solution via a syringe under a nitrogen atmosphere and kept at 0 °C for 1 h. The reaction mixture was continuousl...

Description

technical field [0001] The invention relates to the field of feed, more specifically, the invention relates to a creeper companion and a preparation method thereof. Background technique [0002] Weaning brings physical, psychological and environmental stress to suckling pigs, and often shows a series of adverse phenomena, such as anorexia or refusal to eat, digestive disorders, diarrhea and edema, growth retardation, and low feed utilization. For a long time, the feed preparation and breeding technology of early weaned suckling pigs has been a hot and difficult point in the research of animal nutrition circles at home and abroad. The feed habit of suckling pigs before and after weaning is called creep feed, which is the first time for suckling pigs to eat feed. Therefore, the requirements for creep feed are more stringent. It is necessary to increase weight, produce fast, and improve milk production while ensuring low cost. The immunity of pigs can also help suckling pigs o...
