Functional feed capable of increasing food consumption and milk secretion property of sows and preparation method

Abstract

The invention discloses a functional feed capable of increasing food consumption and milk secretion property of sows and a preparation method. The functional feed comprises the following components inparts by weight: 65-85 parts of deep sea fish dissolving starch, 10-30 parts of fermentation essence, 2-12 parts of composite digestive enzymes and 0.5-6 parts of bacillus subtilis. The functional feed disclosed by the invention is reasonable in design and convenient to use; the deep sea fish dissolving starch is prepared through the steps of performing extraction on deep sea fishes to obtain fish oil, performing squeezing on the fish oil to obtain fresh fish dissolving slurry, performing concentration, performing enzymolysis and performing low-temperature drying, contains rich food-calling peptide, has strong fresh fragrance of sea fishes, and has extremely strong food-calling effects; and the fish dissolving slurry is rich in deep sea fish small peptide after enzymolysis, the structureof the deep sea fish small peptide is quite similar with that of pig protein, and the deep sea fish small peptide is extremely easy to digest and absorb and is directly converted into pork body protein, so that the problems that raw materials of conventional fish meal are low in digestibility, are not fresh, contain antinutritional factors, and influence the health of sows and piggies produced bythe sows are solved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a functional feed capable of improving feed intake and lactation performance of sows and a preparation method thereof. Background technique [0002] In modern large-scale pig farms, low feed intake and poor lactation performance of sows have always been the main troubles of pig farms. The reason is that traditional sow feed generally uses soybean meal and fish meal as the main protein raw material, and soybean meal contains a variety of soybean antinutritional factors (Antinutritional factors, ANF), and the quality of imported fish meal is uneven, such as volatile basic nitrogen (VBN) and Histamine is high, or it is easy to contaminate E. coli, Salmonella, etc. during processing and transportation, resulting in low feed intake and poor nutrient digestion and absorption; Ingestion of feed containing growth-promoting antibiotics can easily lead to the imbalance of benefic...

AI Technical Summary

Problems solved by technology

Due to the low feed intake of sows during lactation, insufficient nutrition and excessive weaning weight loss will directly affect the estrus rate and time interval of sows after weaning, increase the number of non-productive days of sows throughout the year, and thus reduce the farm's economy. benefit
