Weaning of burdock is a very important part of the process of raising cattle. However, most beef cattle farmers do not pay much attention to it. There are various problems in the weaning of burdock, which affects the profitability of cattle farm to some extent. Out. Today, Xiaobian introduces in detail the various problems related to weaning of burdock, and hopes to help the majority of beef cattle farmers.
1. When is the best calf?
Beef cattle farmers generally use natural weaning, which means that the calf is breast-fed with cows until it is naturally weaned. It usually takes at least 6 months for the cow to breastfeed. The calf will grow more and more with the growth of milk, and the cow's lactation pressure will become larger and larger. Many lactating cows are thin bones. In this case, the cows will be delayed. Estrus time, the reason why some cows do not estrus for half a year after birth or even longer is here.
Xiao Bian feels that early calf weaning is necessary for postpartum recovery of cows and rapid entry into the next breeding cycle, but it should not be too early. Generally, weaning is best at 3 to 4 months of age, depending on the body and environment of the calf. Factors determine that, for example, the calf body is poor or the winter temperature is low, it can be weaned later, and the calf is strong and the temperature is suitable for early weaning.
Of course, many beef cattle farmers will ask why the burdock can not be weaned too early. It is not necessary to wean the beef cattle. It is not necessary to wean the milk too early. If the rumen is too early, the rumen is not fully developed and it is difficult to completely digest the forage and feed. Therefore, it is difficult to adequately obtain the nutrients needed for growth and development, which in turn affects the normal growth and development of the calf, and it is not only slow to form a "frozen cow", but also susceptible to various bovine diseases due to poor resistance and adaptability.
2, the burdock opens the feeding as soon as possible
It is very important for the burdock to open the feeding as soon as possible. First, it can promote the rumen development of the burdock. Secondly, it can reduce the dependence of the burdock on the breast milk. Thirdly, it can provide certain nutrition for the burdock.
Before and after the 10th day of age, the burdock can use the fragrant, sweet granules or concentrate (optional sucking pig opening material) as an opening material to attract food. The burdock forms a feeding reflection through the action of smelling and licking the opening material. Generally, 50 to 100 grams of open material can be eaten before and after 15 days of age. There are also many people who say that burdock uses forage to open the mouth. Xiao Bian thinks it is not advisable. At least the burdock should not use forage before opening at 20 days of age, because at this time the rumen rumen is not yet fully developed and it is difficult to digest and absorb the forage.
After the burdock is opened, the opening material can be gradually changed into a general concentrate, and the amount of concentrate feeding is appropriately increased as the burdock grows. After the burdock reaches 20 days old, it can be properly fed with some grass. It should be soft and digestible green hay. It is best to add water to soften it when it is first fed. The burdock will stimulate the rumen and its stomach after starting to feed the forage. Development, usually at least 100 grams of forage (dry matter mass) can be taken every day after 30 days of age.
After the burdock can normally consume the concentrate and the forage, the opening feeding work is basically completed, and only the amount of concentrate and forage can be increased continuously with the growth of the burdock.
3, introduction of burdock weaning method
Burdock weaning can be divided into two methods: one-time weaning and gradually weaning. The one-time weaning is to break the milk between the calf and the cow suddenly. The method is direct and simple, but the stress on the calf is relatively large, suitable for 5-6 months old. The above larger burdock, and the burdock of 3 to 4 months old or smaller is best to be gradually weaned. The specific operation method is as follows.
Separate the burdocks that need to be weaned from the cows. It is best to see them in separate bars. The burdocks are placed in the cow bar 3 times a day for breastfeeding. The time for each breastfeeding is 1~2 hours, and every 2~ Reduce breastfeeding once in 3 days. When the number of breastfeeding is reduced to one time per day, the time for each breastfeeding can be gradually reduced. Generally, after 3 to 5 days, the calf can be stopped. During the period of weaning, we must gradually increase the amount of concentrate and forage to provide sufficient nutrition for the calf. At the same time, we need to feed some live bacteria preparations and electrolysis to enhance the digestive capacity and anti-stress ability of the calf.
4, burdock diarrhea prevention and treatment methods
During the weaning period of burdock, the stress response is large, the resistance is decreased, and the inability to fully adapt to independent feeding, etc., is particularly prone to problems such as indigestion and diarrhea. Therefore, the prevention and treatment of burdock diarrhea must be strengthened during the period. The barn needs to be cleaned, windowed and disinfected regularly to reduce the growth and prevalence of pathogenic bacteria such as Escherichia coli and Salmonella. The temperature of the barn should be kept at 12~25°C. When the temperature is too low, the pad should be laid. Grass, avoiding burdocks directly on the cold ground to cause diarrhea; feeding soft and digestible forage feed, banned from inferior, mildewed and frozen forage feed, timing quantitative, less feeding, and Appropriate amounts of stomach and microbial preparations can be added to the feed to maintain good appetite and digestion.
When burdock occurs in general digestive diarrhea, it can reduce the amount of feed and give some stomach-to-digestive drugs. When bacterial diarrhea occurs, gentamicin, colistin sulfate and sulfonamides can be selected for treatment. Avoid oral administration, because the burdock needs to rely on microbes in the rumen to initially decompose the forage feed, and oral administration will cause certain damage to the rumen microbiota; in case of severe diarrhea, intravenous infusion is needed to prevent dehydration. Adjust electrolyte balance and so on.
The above is about the introduction of burdock weaning. In fact, for this weaning problem, there are really many problems, and farmers still need to fully understand. I hope that the content shared by Xiaobian can help the majority of farmers.
Dried fruit products as the name implies, dried fruit products are pre-treated fruits after selection, washing and dehydration to the water content of 15 ~ 25% products. The volume of dried fruit is about 11 ~ 31% of that of Fresh Fruit, and the weight is about 10 ~ 25% of that of fresh fruit, so it can significantly save the cost of packaging, storage and transportation, and it is easy to eat and carry. Common dried fruits are raisins, red dates, dried mango, dried kiwi, dried strawberry and so on.
