Problems solved by technology

The CMT method is a standard method recognized in the industry to detect recessive mastitis in dairy cows, but it is not convenient for the production of cattle farms, just like the PH value method, silver chloride and milk conductivity method, multiple PCR detection and other detection methods. Defects of mass, frequent, and convenient use, time-consuming and labor-intensive, and high detection costs

Embodiment 1

[0027] Example 1: System for screening dairy cows with recessive mastitis in a herd

[0028] Such as figure 1 As shown, the system for screening cows with recessive mastitis in a herd includes a milk composition analyzer: used to collect information on the milk fat rate, milk protein rate and somatic cell count of individual cows;

[0029] Information acquisition and entry module: used to receive the milk fat rate, milk protein rate and somatic cell number information of individual cows collected by the milk composition analyzer; and enter the cow parity, lactation days, lactation season and milk production information ;

[0030] Parameter correlation analysis module: used to receive the milk fat rate, milk protein rate, somatic cell number, dairy cow parity, lactation days, lactation season and milk production information obtained from the information acquisition and entry module, and compare the above information with Perform correlation analysis on the incidence of recessive mas...

Embodiment 2

[0043] Example 2: Application example of a system for screening dairy cows for recessive mastitis in a herd

[0044] Randomly select 420 lactating cows from three large-scale cattle farms in Jinan City, Shandong Province, and collect relevant data, collect milk samples and determine milk components. The system of the present invention is used to calculate the SMI index of the cows. , According to SMI 1 > SMI 0 The principle of screening cows for recessive mastitis; while taking milk samples, cattle farm veterinarians use the CMT method to judge whether the cows have recessive mastitis. The judgment standard is that only one of the four milk areas of an individual cow If the breast area is positive, it is judged as an individual suffering from latent mastitis.

[0045] Specific steps are as follows:

[0046] (1) Collect milk samples from the test herd, and record the time of collection, milk production of individual cows, lactation days and parity.

[0047] At three large-scale cattle...

Abstract

The invention discloses a system for screening dairy cows having recessive mastitis among cattle. The system includes a milk component analytic instrument, an information acquiring and inputting module, a parameter correlation analysis module, a multiple regression equation establishment module, and a dairy cow recessive mastitis attack percentage cut-off point determining module. The system is used for quickly, easily and accurately screening the dairy cows having recessive mastitis from a dairy cow group, so that cow farm managers can know which cows are suffered from the recessive mastitis timely and definitely, thereby providing guarantee for prevention and treatment on the mastitis among dairy cows.

Description

Technical field [0001] The invention relates to a system for screening dairy cows with recessive mastitis in a herd, and belongs to the technical field of disease screening. Background technique [0002] Dairy cattle breeding is an important part of my country's animal husbandry, and it plays an important role in the national economy and people's lives. With the development of the national economy and the change of people's dietary concepts, safe, healthy and nutritious dairy products are increasingly expected by consumers. In the production of dairy cows, dairy cow mastitis not only directly affects the milk production, milk component content and physical and chemical properties of individual cows, but also affects the safety and nutritional value of dairy products, causing great harm. The causes of mastitis are complex. Compared with clinical mastitis, recessive mastitis (subclinical mastitis) has no clinical symptoms and is not easy to be detected. However, recessive mastitis...
