Colostrum is the milk produced by cows within 7 days of calving. It is the ideal food for calves. Cultivating calves with fermented colostrum has the advantages of increasing the survival rate of calves, promoting growth and development, enhancing disease resistance, saving the consumption of commercial milk, reducing costs, and improving economic efficiency.
First, make and use
1. Natural fermentation. The newly-extruded colostrum is filtered and poured into a plastic bucket, which is timely covered with a lid (not too full to prevent overflow after fermentation), and allowed to naturally ferment at room temperature. In the fermentation process, it is stirred 1-2 times a day, and the fermentation is successful at room temperature 10°C-15°C for 5-7 days, 15°C-20°C for fermentation 3-4 days, 20°C-25°C for two days.
2. Starter fermentation. The filtered colostrum is filtered and heated to 70°C-80°C. Then it is cooled to about 40°C and poured into a plastic bucket. The starter is added (5% in summer and 7% in winter). Cover the lid well. In the fermentation process, stirring 1-2 times a day, at room temperature 10 °C, about two days into the fermentation of colostrum, 20 °C -25 °C only 1 day.
3. Feeding method and feeding amount. Fermented colostrum must be well-mixed before feeding calves, then press 1:1 or
Warm water was added in a ratio of 1:2 to keep the milk temperature around 37°C. Second, in order to achieve the purpose of exercising calf gastrointestinal function. On the seventh day, cooked boiled porridge was added to the fermented colostrum every day, three times a day, and the total amount was controlled at about 50 grams each time. Starting from the tenth day, the training of calves to feed concentrates and forages is gradually increased from little to large. Generally, the entire training process is completed by the age of 30 days. At this time, calves consume a total of 0.75 kg of fine concentrate per day. About the same time, the amount of mixed concentrate fed will gradually increase with the weight gain of calves. After 75 days of age, no more fermented colostrum was fed and more than 1.65 kg of mixed concentrate was fed.
Second, save
If fermented colostrum can not be fed in a short time, it is best kept in the refrigerator or other refrigerated equipment. If there is no refrigeration equipment, it should be stored in the cellar, or add 0.1% formaldehyde solution in a concentration of 37% in the fermented colostrum, and then mix thoroughly and seal it. This method is simple, low-cost and can be stored for about 2 months.
Third, pay attention to matters
1. The suitable temperature of fermented colostrum is 20°C-25°C. If you find that the temperature is too high and the acidity is too high, immediately place it in cold running water or in a cool, damp place.
2. Cows suffering from mastitis or who have used antibiotics within two weeks before birth should not use colostrum to make fermented colostrum.
