Here is the advice from Chen Xinjun, a teacher from Taiping animal husbandry office in Zhanjiang, Guangdong Province Preparation before cow production: sterilize a pair of scissors (boiled water or sterilized with alcohol); clean 2-3 towels or cloth (boiled water and dried in the sun); sterilize 2 thread (hemp) ropes During cow production, clean cereal grass and wheat straw shall be used as liner After the calves are born, first wipe the mucus from the mouth and nose with a clean cloth or towel to prevent the calves from inhaling mucus and causing breathing difficulties The mucus should also be dried to avoid cold In addition, after the calves are born, the umbilical cord is not broken, so we should help to break the umbilical cord The method is as follows: 10 cm from the navel, disinfect with 5% iodine and squeeze out the blood in the umbilical cord by hand, tie two knots at the upper and lower ends of the place with sterilized rope, then cut with scissors, and then apply iodine to the section for disinfection Because of more blood loss and energy consumption, cows should be given energy Feed 15kg of warm and sufficient bran, salt, calcium and congee (bran 1-2kg, salt 100-150g, calcium carbonate 50g), and feed 1-2kg of high-quality and soft hay Let the calves eat colostrum as early as possible - that is, the milk produced by the cow within one week after the birth of the calf Colostrum has special functions for the growth and development of the calves It is usually fed about one hour after birth If there is no colostrum, it can be replaced by artificial milk The formula is: 20 eggs, 10g salt, 15g fresh cod liver oil and 250g milk are fully mixed After heating to 38 ℃, they can be fed After the colostrum period, it is transferred to regular feeding, which is fed 2-3 times a day The daily feeding amount is calculated as 10% of the calf's weight After each feeding, use a clean towel to dry the remaining milk at the mouth of the calf and disinfect it regularly The calves can be properly trained to eat plant-based feed in advance Generally, the training material starts from 10-20 days old At the beginning, the refined material is made into congee, and a little milk is added At the beginning of the day, 10-20g is fed, gradually increasing the feeding amount; at the 20th day, 10-20g carrot pieces are fed, gradually increasing the feeding amount later; at the 30th day, hay is put in the column to induce the calves to eat; at the 60th day, silage is added, and the first feeding is done The dosage is 100-150g In addition, proper amount of clear water should be fed The weaning time depends on the growth and development of calves Generally, the calves can be weaned when they can eat about 1kg of calf feed every day The lactation period is generally 3-4 months In order that you can see our reply in time without missing the production period of cattle, we will send you our new issue of magazine as soon as this issue is published We hope you will continue to pay attention to us, and we will try our best to provide you with the latest information and the best service Joyous song
