Problems solved by technology

[0004] At present, antibiotics are the first choice for the treatment of mastitis and brucellosis, but long-term use of antibiotics has brought many hazards, such as the increase of drug-resistant strains, endocrine dysfunction, excessive antibiotic residues and veterinary drug residues, etc., seriously affecting human health
At present, mastitis and brucellosis are mainly treated. When the disease occurs, it has already had an important impact on the lactation and reproduction of dairy cows. Feed additives used to prevent mastitis and brucellosis in dairy cows are rarely seen.

Embodiment 1

[0034] Embodiment 1: the preparation of yeast culture

[0035] 1) Seed solution preparation: Candida utilis ( Candida utilis ) CGMCC NO.7691 was inoculated into the liquid seed medium to obtain the seed liquid. The liquid seed medium contained: molasses 10-20g / L, peptone 10-20g / L, sodium chloride 5-25g / L, pH 5.5-7.0, the seed culture conditions are: shaker culture, rotation speed 150-200r / min, temperature 28-32 ℃, culture time 18-24h;

[0036] 2) Liquid aerobic fermentation: Inoculate the seed liquid into the liquid fermentation medium of the fermenter, scale up the culture, and carry out aerobic fermentation to obtain a liquid strain solution. The liquid fermentation medium contains: molasses 40-80g / L , peptone 30-50g / L, sodium chloride 5-25 g / L, MgSO4•7H2O 1-5 g / L, pH 5.5-7.0, liquid aerobic fermentation conditions: inoculum size 10-20%, ventilation volume 1 -3L / min, stirring speed 200-400r / min, using the fermenter pH automatic feedback adjustment system to control the pH ...

Embodiment 2

[0044] Embodiment 2: be used for the preparation of the feed additive of prevention milk cow mastitis and brucellosis

[0045] (1) Weigh the raw materials according to 50% yeast culture, 8% cecropin, 10% medlar, 10% jujube, 10% safflower, 8% white peony root and 4% montmorillonite;

[0046] (2) Mix the weighed raw materials, crush them to about 40-60 mesh, and mix well to obtain the feed additive for preventing mastitis and brucellosis in dairy cows of the present invention.

Embodiment 3

[0047] Embodiment 3: be used for the preparation of the feed additive of prevention milk cow mastitis and brucellosis

[0048] (1) Weigh the raw materials according to 60% of yeast culture, 6% of cecropin, 6% of medlar, 8% of jujube, 6% of safflower, 10% of white peony and 4% of montmorillonite;

[0049] (2) Mix the weighed raw materials, crush them to about 40-60 mesh, and mix well to obtain the feed additive for preventing mastitis and brucellosis in dairy cows of the present invention.

Abstract

The invention relates to a feed additive for preventing dairy cow mastitis and brucellosis, which belongs to the technical field of feed. It is composed of the following raw materials in weight percentage: yeast culture 35-60%, cecropin 1-10%, medlar 8-15%, jujube 8-15%, safflower 5-10%, white peony 5-10% % and montmorillonite 4‑8%. The feed additive of the invention can effectively prevent cow mastitis and brucellosis, improve the health status of cows, and avoid the influence of mastitis and other diseases on cow output and milk product quality. By adopting the feed additive of the invention, the economic benefits of dairy cow breeding are greatly improved, and the adverse effects of the use of antibiotics on the quality of dairy products and the health of dairy cows can be avoided.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed additive for preventing cow mastitis and brucellosis and a preparation method thereof. Background technique [0002] Mastitis, especially invisible mastitis, is a breast disease with a high incidence rate during the lactation period of dairy cows. It can cause a sharp decline in the lactation skills and milk production of affected cows, and cause reproductive dysfunction in dairy cows. It has become a common and frequently-occurring disease in dairy farms , seriously restricting the development of the dairy industry. According to statistics, once mastitis occurs in dairy cows, the milk production will drop by 8% on average, 5% in mild cases, and 26%-10% in severe cases. The incidence of mastitis in dairy cows in my country is very high. According to the survey results of Yuan Yonglong and others, the average incidence of clinical mastitis is 33.41%, and the avera...
