8-point plan for mastitis prevention and control in dairy farms in China
The fourth phase of the dry milk period breast infection risk management course of the "China Dairy Farm Mastitis Prevention and Control 8 Point Plan" series of open courses has been successfully concluded, as a cattle breeder, have you learned each course? If you haven't had time yet, hurry up and enter the "Boehringer Bull Gas Academy" - "Bull Lecture Hall" for retrospective study.
Dairy mastitis is one of the most costly diseases in pasture production, and the dry milk period is the stage most prone to new infections in the milk area. At the same time, dry milk management can also greatly affect the yield level, reproductive status and health (including udder health) of cows after childbirth. The "8-Point Plan" series of open courses systematically sorted out the risk management of breast glands during the dry milk period from the following topics.
What are the risks of breast infection during dry milk?
How is the risk of breast infection managed during dry milk?
What are the key points in the implementation of selective dry milk therapy?
What are the key points of infection evaluation system and management during dry milk period?
Lesson 1
Dr Peter Edmondson, a British veterinary consultant, was invited to systematically sort out the theoretical knowledge of "what is the risk of breast infection in dry milk" and presented the latest international research results. Do you remember the knowledge points that this theme brings home?
Dry milk infections are a common cause of mastitis;
All cows are at risk of infection during the dry milk period, not just high-yielding cows;
Dry milk medicine does not play a role in preventing infection during the dry milk period;
The cleanliness of the cow's body, udder and nipples needs to be guaranteed throughout the dry milk period;
All dried cows should use nipple blockers;
Nipple blocking agents reduce clinical mastitis by 25% to 30%.
Lesson 2
Dr. Zhang Junjie, technical leader of Boehringer Ingelheim, was invited to explain how to specifically manage the risk of breast infection during the dry milk period on the current situation of domestic facts. Key messages on this topic include:
Clinical mastitis in newly produced cattle is closely related to new infections in the dry milk stage;
The dry milk period is a high-risk stage for new infections in the milk area;
New infections at the dry milk stage are closely related to the formation or absence of keratin suppositories;
The risk of new infections during the dry milk period can be reduced through good dry milk management;
Control the risk of clinical mastitis infection during the dry milk period and produce good returns.
Lesson 3
Gou Wenqiang, Technical Service Specialist of Boehringer, on the topic of "Key Points in the Implementation of Selective Dry Milk Therapy", combined with Belgian Professor Dr. Sofie Piepers' sharing systematically sorted out the main points of dry milk treatment for everyone. Summarize the knowledge points:
If the farm wants to switch from full-herd dry milk to selective dry milk, the best strategy is to adjust according to the actual situation of the herd, such as choosing a healthy herd with good udders;
There is no perfect strategy for the transformation of dry milk methods, and it needs to be selected according to the actual conditions of each farm;
After switching to selective dry milk, when selecting cows, it is more valuable to use somatic cell count data as a reference, and the reference value of bacterial culture is relatively limited;
Compared with the assessment of milk area level, the individual level assessment of cows is more valuable.
Lesson 4
Professor Gao Jian, associate professor of China Agricultural University, brought the knowledge points of "infection evaluation system and management points during dry milk period" mainly as follows:
The occurrence of mastitis in the new cattle stage will cause more serious economic losses and is also the trigger for the repeated occurrence of mastitis throughout the lactation period;
Prevention and control of mastitis in newly produced dairy cows, prevention of infection during the dry milk period is the most important;
The use of nipple blockers + selective dry milk is the trend of the whole group;
The establishment of selective dry milk requires a complete set of evaluation systems, and there is still a long way to go to successfully implement it under the current conditions in China.
Boehringer Bull Gas Academy
The topic of dry milk has come to an end, and the next "8-point plan for the prevention and control of mastitis in China" will bring you the knowledge sharing of the theme of milk hall management. At that time, we will invite well-known experts at home and abroad to elaborate on the management of the milk hall, please pay close attention to the "Boehringer Cow Gas Academy", we will not see you and you!
