Microelement composite additive for improving reproductive performance of pets Technical Field The invention belongs to the technical field of pet nutrition, and particularly relates to a microelement composite additive for improving reproductive performance of pets, and a preparation method and application thereof. Background Optimization of reproductive performance of pets has been an important research direction in the field of pet nutrition and reproduction. With the improvement of the family status of pets and the increase of the refined feeding demand, the market has put higher demands on nutrition additives capable of scientifically, safely and effectively improving the reproductive performance of pets. Trace elements are used as key nutrient substances participating in various physiological metabolism of organisms, play an irreplaceable role in the propagation process of pets, but the application of the prior art in the field still has obvious defects. The existing commercial pet propagation nutritional supplements mainly have the following technical defects that firstly, the formula design is simple and extensive, the single trace element supplement or basic vitamin-mineral premix is mostly adopted, the scientific compatibility research and the synergistic mechanism design are lacked among all the nutritional ingredients, the bioavailability is low, the actual effect is limited, secondly, the raw material selection and treatment process is lag, the inorganic trace element forms still dominate, such as common zinc sulfate, copper sulfate and the like, the absorption rate is low, antagonism reaction is easy to occur to other components, the application of the organic trace element stays on the simple addition level, the biological potency of the organic trace element cannot be fully exerted through the scientific preparation process, thirdly, the stability of the existing product is generally poor, the problems of trace element oxidation, agglomeration, dissolution rate reduction and the like are easy to occur in the storage process, the effective period and the using effect of the product are directly influenced, and fourthly, the application scheme is lacked, the accurate addition time, dosage and period are not designed according to the physiological characteristics of the pet propagation, and the intervention effect is greatly discounted. Particularly, the prior art has insufficient research on the synergic and antagonistic relationship between microelements, and fails to effectively solve the balance problem between key microelements such as selenium, vitamin E, zinc, copper and the like. In terms of preparation process, the conventional simple mixing method is difficult to ensure uniform distribution of trace components, and insufficient protection of thermosensitive nutrients (such as vitamin E) is achieved. In addition, the existing product is mostly neglected to optimally select and process the carrier material, and the influence of the common carrier on the adsorptivity and stability of microelements is considered, so that the effect attenuation of the product in the storage and use processes is obvious.
