Postpartum drenching nutritional supplement for dairy cattle and production method of postpartum drenching nutritional supplement

Abstract

The invention relates to the field of delivery nutritional supplements of dairy cattle, in particular to a postpartum drenching nutritional supplement for dairy cattle and a production method of the postpartum drenching nutritional supplement. Formulae are designed separately according to physiologic characteristics of the first-parity cattle and the multiparity cattle. The formulae comprise the following common ingredients in parts by weight: 1-10 parts of rumen bypass nicotinic acid, 1-20 parts of potassium chloride, 1-20 parts of magnesium sulfate, 1-10 parts of composite material, 1-10 parts of sodium chloride and 1-10 parts of beer yeast extract; the formula for the first-parity cattle further comprises 10-100 parts of solid propylene glycol in addition to the common ingredients; and the formula for the multiparity cattle further comprises 10-20 parts of solid propylene glycol and 10-100 parts of calcium propionate in addition to the common ingredients. With the adoption of the mode, the supplement can timely supply nutrient substances required after delivery of the dairy cattle, reduces incidence of various postpartum diseases, promotes postpartum body condition recovery of the dairy cattle, finally lowers operational cost of a pasture and improves an economic effect of the pasture.

Description

technical field [0001] The invention relates to the field of dairy cow delivery nutritional supplements, in particular to a nutritional supplement for postpartum feeding of dairy cows and a production method thereof. Background technique [0002] In recent years, my country's dairy breeding industry has developed rapidly, and the scale of breeding has continued to expand. However, there are many problems in the breeding process, which greatly affect the health of dairy cows and the income of pastures. Among them, before and after delivery, dairy cows have experienced huge physiological and metabolic changes and a series of stresses, and the probability of disease has greatly increased. Therefore, the care of dairy cows before and after delivery is a key link in pasture management, which plays an important role in the health of dairy cows and the economic benefits of pastures. pivotal role. [0003] Before and after the cow gives birth, a large amount of blood calcium enters...

AI Technical Summary

Problems solved by technology

[0005] At present, domestic pastures mostly use propylene glycol, calcium chloride and other composition measures to deal with it after delivery. However, the composition of the pasture self-prepared by the pasture lacks scientific proof and reasonable proportioning

However, commercial gavage agents sold on the market are not designed for the physiological characteristics of first-born cows and second-born cows. First-born cows have sufficient blood calcium and bone calcium, so there is no need to supplement calcium. Supplementation will easily increase the burden on the heart of dairy cows. Insufficient blood calcium and bone calcium in multi-partured cattle require a large amount of calcium supplementation, and the effect will be uneven if there is no differentiated design

Moreover, most of the existing fillings are liquid or need to be used in combination with liquid packs, which is inconvenient for transportation and storage.
