A dairy cattle feed additive and a breeding method for dairy cattle in an early perinatal period

Abstract

A dairy cattle feed additive and a breeding method for dairy cattle in an early perinatal period are provided. The additive comprises 1.6-2.6 wt% of rumen-protected choline, 1.4-2.6 wt% of rumen-protected methionine, 30-80 wt% of rumen-protected glucose, 1-2.6 wt% of selenium yeast, 0.4-1.6 wt% of astragalus polysaccharide, 1-2.2 wt% of sodium humate, 2-6 wt% of antibacterial peptide, 1-2.2 wt% of nicotinic acid, 1-2.2 wt% of ammonium chloride and 20-60 wt% of a carrier. The breeding method for the dairy cattle in the early perinatal period through adopting the dairy cattle feed additive is also disclosed. The additive can be directly fed to the dairy cattle and is suitable for the dairy cattle in the early perinatal period. The additive is capable of reducing postpartum energy negative balance for the dairy cattle, increasing dry matter intake and the milk yield of the dairy cattle, promoting dairy cattle health, reducing dairy cattle postpartum diseases and reducing the dairy cattle postpartum elimination rate, and has popularization and using value.

Description

technical field [0001] The invention relates to a dairy cow feed additive and a feeding method for dairy cows in the peripartum period, belonging to the technical field of dairy cow feeding. Background technique [0002] The transition period of dairy cows (TransitionPeriod) refers to the period of the perinatal period (21 days) before and after the delivery of dairy cows and the postpartum period (21 days) after delivery, which includes late pregnancy and early lactation. The most critical stage in life, of which the perinatal period is particularly important. [0003] Dairy cows in the peripartum period experience great stress in many aspects such as nutrition, physiology and metabolism, and need to adjust their own glucose metabolism, fatty acid metabolism and mineral metabolism to meet the needs of lactation. During the peripartum period, the feed intake of dairy cows decreases by 20-30%, and the level of non-esterified fatty acids in the blood increases, which will cau...

Problems solved by technology

At the same time, during this stress period, the resistance of dairy cows will be reduced, and the absorption rate of nutrients will also be reduced. If the disease resistance of dairy cows is not improved in time, it will lead to postpartum retained placenta, induced ketosis, mastitis, hoof disease, Diseases such as puerperal fever can affect the health of dairy cows, reduce milk production, cause dairy cows to have no milk after giving birth, affect the reproductive rate, and cause death of dairy cows, causing serious economic losses to pastures.
