Embodiment 1

[0009] Mix 50 parts of borax, 47 parts of boric acid and 1 part of potassium bromide phenol violet, and then mix them with 190 parts of sodium lauryl sulfate to form a light yellow solid powder. The powder is divided into plastic bottles, and each bottle contains 15.45 grams of powder for subsequent use.

[0010] Before use, dissolve the powder in 1 bottle in warm water, the final volume is 500ml, and the pH is 7.3-7.5. This liquid can be used for the diagnosis of dairy cow recessive mastitis.

Embodiment 2

[0012] Mix 70 parts of borax, 49 parts of boric acid and 1 part of potassium bromide phenol violet, and then mix them with 210 parts of sodium lauryl sulfate to form a light yellow solid powder. The powder is divided into plastic bottles, and each bottle contains 15.45 grams of powder for subsequent use.

[0013] Before use, dissolve the powder in 1 bottle in warm water, the final volume is 500ml, and the pH is 7.3-7.5. This liquid can be used for the diagnosis of dairy cow recessive mastitis.

Embodiment 3

[0015] Mix 240 grams of boric acid (product of Shanghai Guanghua Technology Co., Ltd.), 300 grams of borax (product of Jiangsu Taicang Chemical No. 2 Factory) and 5 grams of bromopotassium phenol purple (product of Shanghai Sansi Reagent Co., Ltd.), Sodium (Xiamen Xinglongda (Sanland) Chemical Reagent Co., Ltd. product) 1000 g was mixed evenly to form light yellow solid powder. The powder is divided into plastic bottles, and each bottle contains 15.45 grams of powder for subsequent use.

[0016] Before use, dissolve the powder in 1 bottle in warm water, the final volume is 500ml, and the pH is 7.3-7.5. This liquid can be used for the diagnosis of dairy cow recessive mastitis.

Abstract

The invention discloses a cow recessive mastitis diagnostic agent and the preparing method, uniformly mixing borax 50-70 shares, boric acid 47-49 shares, and bromcresol purple 1 share, then mixing with dodecyl sodium sulfate 190-210 shares, thus making primrose solid powder, taking the powder 15.45 g to dissolve in 500 ml water so as to form purplish-red liquid, able to be used for diagnosing the cow recessive mastitis. The agent is the same as CMT and can indirectly determine somatocyte content of a cow, simple to operate and able to make field detection, and especially, the powder of the agent has more advantages, such as small bulk, lightweight, convenience of carrying and storing and extremely suitable for large- volume detection.

Description

technical field [0001] The invention relates to a diagnostic reagent for dairy cow recessive mastitis and a preparation method thereof. technical background [0002] Invisible mastitis in dairy cows is easily overlooked because it has no clinical symptoms visible to the naked eye. But the incidence rate is high, and it is easy to transform into clinical mastitis. According to reports in the United States, generally 48-49% of dairy cows suffer from invisible mastitis. Due to the poor management level and sanitary conditions in China, the situation is more serious, the incidence rate can reach more than 65-70%, and the output and quality of affected milk are significantly reduced, so it is extremely harmful. [0003] In the milk of cows with subclinical mastitis, in addition to the composition and physical and chemical properties of physical and chemical properties change at the same time. The number of somatic cells also increased substantially. Currently used diagnostic ...
