The invention provides novel formulations comprising a stable inclusion complex of tributyrin and a cyclodextrin. In one particular embodiment, the formulation comprises an oven dried inclusion complex of tributyrin and γ-cyclodextrin that is effective in minimizing or preventing the unpleasant taste and odor of tributyrin, thus making it suitable for oral administration and delivery to the digestive tract and intestines. The invention provides compositions of these inclusion complexes and methods of using them that are advantageous as food, medicinal and other products, where the negative sensory properties of tributyrin can be a liability.

The invention discloses a method for enzymatic inclusion of tributyrin, which belongs to the technical field of oil microencapsulation. The present invention combines enzymatic synthesis of cyclodextrin and cyclodextrin inclusion tributyrin, including CGT enzymatic preparation of cyclodextrin, adding tributyrin in the preparation process, adding Tween after the reaction, all quality, spray-dried. The effect of the finally obtained tributyrin powder is far better than that of a single cyclodextrin inclusion. The invention has the advantages of simple process, low cost, convenient operation, non-toxicity and pollution in the reaction process, no toxic reagent residue, remarkable clathrate effect, and is conducive to better utilization of tributyrin as a nutritional additive in actual production.

The invention relates to a premix capable of promoting growth and reproduction of sows, as well as a preparation method and an application thereof. In parts by weight, per 1000 parts of the premix capable of promoting growth and reproduction of the sows comprises the following ingredients: 15-30 parts of selenium yeast, 150-200 parts of glycine chelated manganese, 36-50 part of copper lysine, 0.1-0.2 part of chromium picolinate, 1-2 parts of folic acid, 20-80 parts of linseed meal, 50-200 parts of glyceryl butyrate, and the balance carriers. The premix is added into basic daily feeds of the sows in a dosage that the addition amount of the premix is 0.5-1% of the total mass of the basic daily feeds of the sows. Compared with the prior art, the premix disclosed by the invention is capable of effectively improving food intake and milk yield of the sows, as well as satisfying nutrition needs so as to ensure nutrition, healthy development and production performance of the sows and the piglets. The premix promotes growth and breeding of the sows, and improves intestinal immune functions; moreover, the premix improves lactation performance, and reduces weight and back fat loss of the sows in the lactation period. In addition, the premix satisfies macro-element and trace-element needs of the sows in the breeding cycles, as well as improves absorption and utilization rates and reduces pollution to the environment.

An enzymatic method for preparing glyceryl butyrate, comprising: (1) carrying out an esterification reaction between n-butyric acid and glycerol using lipase as a catalyst, ethyl acetate and / or ethyl formate as an additive; (2) separating the reaction product, recovering the additive by distillation under reduced pressure to obtain glyceryl butyrate. The invention uses lipase as a catalyst to catalyze the esterification reaction of n-butyric acid and glycerin at normal temperature and normal pressure, reduces the energy consumption of the reaction. Also, the reaction condition is mild, no side reaction happens, and no water-carrying agent is used. In addition, the additive increases the catalytic efficiency of the lipase and the conversion rate of butyric acid.

The invention relates to a composite feed additive for restoring baby pig intestine mucosal injury, belonging to the technical field of feed additives for baby pigs. The feed additive comprises 0.1-0.2 part of glutamine, 0.01-0.1 part of butyrin, 0.01-0.1 part of yeast nucleic acid, 0.02-0.2 part of threonine, 0.03-0.3 part of origanum oil, 0.03-0.3 part of chitooligosaccharide, 0.1-0.5 part of active dry yeast, 0.1-0.5 part of Bacillus subtilis, 0.11-0.3 part of vitamin and 5-7.5 parts of carrier. On the basis of the basic principles of baby pig intestinal tract nutrition, intestinal tract immunity and intestinal tract microecology, the invention can effectively restore baby pig intestine mucosal injury, accelerate the growth of baby pigs, and promote the health and immunity of the baby pig intestinal tract, thereby enhancing the survival rate and growth rate of the baby pigs.

The invention discloses a use of an oil and fat composition in preparing pig and poultry feed, a feed additive and a feed. Wherein, the feed additive includes glycerol monobutyrate, glycerol tricaproate, glycerol trilactate and auxiliary materials, wherein, by weight, 0.5 to 1 part of glycerol monobutyrate and 1 part of glycerol tricaproate ~ 2 parts, 1 part trilactide. The technical scheme of the invention can reduce the body fat content of pigs and poultry, increase the percentage of lean meat and poultry breast, and reduce the cost of feed additives.
