Embodiment 1
[0040] Embodiment 1 Utilizes the method of rumen flora transplantation technology to improve the feed intake and milk production of dairy cows in the postpartum period
[0041] (1) Test animals
[0042] Donor cows: Select 5 healthy dairy cows with the same parity, similar body condition, and 60-80 days before delivery, install ruminal fistula, and put them into the dry cow barn after 2 weeks of isolation and nursing, and follow the normal conditions of the dairy farm. Feeding and management plan: Feeding and management are carried out, and all mixed rations are used for feeding, 3 times a day, free activities, free access to food, and free drinking water.
[0043] Recipient cows: 15 healthy dairy cows with the same parity, similar body condition, and 30 days before delivery were selected and transferred to the test pen to make the test cows adapt to the automatic feeding trough in advance. The day of delivery was recorded as day 0 to enter the test period, and 30 peripartum d...

The invention provides a method for increasing the feed intake and the milk yield of late perinatal diary cattle by means of rumen flora transplanting. By means of the rumen microflora transplanting technology, rumen fluid and / or a fermentation product thereof of healthy diary cattle which is in an intake peak and lactation peak state 80-120 days after delivery is transplanted into rumens of the late perinatal diary cattle, and therefore the feed intake of the late perinatal diary cattle and the milk yield of the early lactation diary cattle are increased. According to the method, the rumen and intestine microflora of the late perinatal diary cattle is rebuilt through transplanting, the postnatal feed intake of the late perinatal diary cattle is increased, the postnatal nutrient requirement of the diary cattle is met, negative balance of energy is prevented and controlled, then the milk yield is increased, and the important industrial and commercial value is achieved for increasing the diary cattle farming benefit and enhancing the international competitiveness of China.
Description
technical field [0001] The invention relates to the field of dairy cow microbiology and nutrition, in particular to a method for improving feed intake and milk production of dairy cows in the postpartum period by using rumen flora transplantation technology. Background technique [0002] my country is an important agricultural country and a big milk producing country in the world. Since the beginning of the 21st century, my country's dairy industry has developed rapidly, and the structure of dairy farming has been continuously adjusted and optimized, gradually transforming to scale, standardization, intensification and modernization. In 2015, the proportion of large-scale breeding with more than 100 cows reached 48.3%. However, in the process of transformation, the low yield of dairy cows is one of the main bottlenecks restricting the sustainable development of China's dairy farming industry, which is also one of the main reasons for the lack of international competitiveness...
