Feed additive for preventing cow subclinical mastitis and preparation method thereof

Abstract

The invention discloses a feed additive for preventing cow subclinical mastitis and a preparation method thereof. The feed additive is prepared from 9-12 parts by weight of fructus forsythia, 15-30 parts by weight of mangosteen shells, 30-40 parts by weight of fresh Malabar spinach, 20-30 parts by weight of fresh enteromorpha prolifera, 2-4 parts by weight of clam powder, 6-9 parts by weight of snake bramble seeds, 6-9 parts by weight of root of root of Polygonum divaricatum L., 4-7 parts by weight of impatiens noli-tangere, 3-5 parts by weight of moutan bark, 9-12 parts by weight of radix angelicae dahuricae, 15-20 parts by weight of fresh purslane, 10-15 parts by weight of fresh ginseng fruits, 5-8 parts by weight of roasted radix licorice, 8-10 parts by weight of jack fruit pulp and 9-12 parts by weight of leaves and fruits of Eucalyptus globules. The feed additive improves a milk yield, reduces cow mastitis morbidity, supplies vitamins and trace elements for cows, effectively prevents antibiotic and hormone use, prevents milk product pollution and ensures milk product eating safety.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing milk cow recessive mastitis and a preparation method thereof. Background technique [0002] Mastitis is a common disease of dairy cows, generally divided into two categories: clinical mastitis and recessive mastitis. Because the symptoms of subclinical mastitis are mild, it is often ignored by people. It not only seriously affects the milk production and milk quality of sick cows, prolongs the postpartum estrus and pregnancy time, but also easily spreads among cattle, causing serious losses to the dairy industry. , At the same time, the quality of milk changes, and it will endanger human health. Therefore, it is of great significance to actively prevent and control recessive mastitis in dairy cows. The economic losses caused by mastitis include decreased milk production performance, increased costs of substitutes, discarded raw milk, drug costs, and increased ve...

Problems solved by technology

In addition, the content of lactose, casein, fat, Na, P, and other beneficial ingredients are all reduced or significantly reduced, and the thermal stability is also reduced

[0003] At present, dairy farmers generally use antibiotics to treat mastitis in cows. Although good results have been achieved, there are a series of problems such as drug residues, drug resistance of pathogenic bacteria, environmental problems, and human health.
