How long does it take for a calf to be weaned and how many days a cow can calve at the latest

One is weaning at 110 days and weighing 170 kg at 6 months;

The other is weaning at 60 days and weighing 160-165 kg at 6 months of age. In order to intensively fatten calves after early weaning, they can be used to their advantage in order to reach the desired goals in a shorter time. At present, there is an early weaning method, which is about 46 days for weaning.

How much concentrate do calves give per day after weaning?

Small amounts are done gradually.

1 At 6 months of age, in addition to the kilogram of concentrate feed, the initial feeding was 133 kilograms. The average daily weight gain is 680 grams.

It is best to start feeding the calves at 3 weeks of age. Because calves are born soon (within 3 weeks of age), their forestomach (rumen, reticulum, valve stomach) is very small and tender, does not have digestive function, and there are no microorganisms and ciliates, so they can only eat milk into the real stomach (wrinkled stomach) for absorption and utilization. If you feed forage at this time, it will increase the burden on the rumen, reticulum and valve stomach, causing morbidity.

If the forage is fed too late, the stomach and intestines rely on the milk of the flowing juice for a long time, and the rumen, net stomach, and valve stomach can not be exercised, and the growth and development of these three stomachs is slow, and its content is too small, and it eats less in youth and adulthood, which affects growth and development and health.

After 3 weeks of age, the rumen, reticulum, and valve stomach of calves increase rapidly, and microorganisms enter the forestomach due to contact with small amounts of food and water, and at this time, calves also begin to ruminate.

At this time, they begin to feed the fresh grass and wild vegetables.

Vegetables, leaves, high-quality dry grass, crushed concentrate, etc., and increase the amount of feed and roughage with the extension of age. In this way, it not only avoids the disease caused by the too young and tender forestomach, but also promotes the acceleration of the development of the forestomach, promotes the reproduction of rumen microorganisms, gradually enhances the function of digesting feed, and lays a good foundation for the future intake of a large amount of roughage to ensure normal growth and development.

Heatstroke prevention and cooling measures for calves in summer.

1. Shade. If the beef cattle fattening farm adopts a tethered feeding method to restrict the movement of cattle, in the summer high temperature, the cattle should be tied to the shade of a tree or under a shed ventilated on all sides to prevent direct sunlight. Tethering should also pay attention to changing the location of the tether as the angle of sunlight changes to prevent direct sunlight exposure to the cattle, and it is best to let the cattle move freely in the sports field.

Unless there is no wall around the sports field in the cold season, it is not conducive to ventilation and cooling.

Generally, it is better to be completely weaned at the age of 3 to 4 months, which needs to be determined according to factors such as calf constitution and environment, such as poor calf constitution or low temperature in winter, we can weaning later, and calves can be weaned earlier if we have strong constitution and suitable temperature.

Note: Weaning radically changes the calf's diet and can sometimes cause a stress response in the calf. In order to reduce the adverse effects of weaning on calves, a step-by-step principle should be adopted.

That is, 15 days before the scheduled weaning, the amount of concentrate and roughage should be gradually increased, and the amount of milk should be gradually reduced. The number of feedings per day was changed from 3 to 2, 2 to 1, and then 1 every other day. Also fed to 1:1 at weaning

1 of the water mixed with buffalo milk, and gradually increase the amount of water, after a few days completely replaced by warm boiled water.

During weaning, the ambient temperature is maintained (10 30 °C), the barn is clean and clean, with plenty of drinking water, and the calves are provided with nutritious, easily digestible concentrate and good quality green hay. During the weaning period, the breeder should maintain relative stability, and observe the behavior of the calves, and find abnormal phenomena, which should be reported in time and asked the technician to solve it.

Summary. Hello, calves are generally weaned for about 7 days. It is best to choose the season when the temperature is mild, and strong calves can be weaned in about three months.

On the other hand, if a weak calf is sickly, it is usually weaned at about four months. Under normal circumstances, if a 45-day-old calf has been able to eat more than three pounds of feed for more than three consecutive days, it can be weaned. After weaning, additives such as salt and sugar can be added to the feed to improve the palatability of the feed and increase the feed intake of the calves.

Hello, then the wide calf weaning generally has to go through 7 days left track to accompany the right. It is best to choose the season when the temperature is mild, and strong calves can be weaned in about three months. On the other hand, if a weak calf is sickly, it is usually weaned at about four months.

Under normal circumstances, if a 45-day-old calf has been able to eat more than three pounds of feed for more than three consecutive days, it can be weaned. After weaning, additives such as salt and sugar can be added to the feed to improve the palatability of the feed and increase the feed intake of the calves.

There are also theories that in order to fatten as soon as possible, strong calves can be weaned early in about fifty days.

The gestation period of a cow is generally between 275 and 285 days, so the cow calves at the latest 285 days. The length of gestation varies depending on factors such as breed, age, season, feeding management and fetal sex. Early maturing breeds have a shorter gestation period, dairy cows have a shorter gestation period than beef cattle, young cows have a shorter gestation period than adult cows, carry twins 3 to 6 days shorter than have a single child, and give birth in winter and spring 2 to 3 days longer than in summer and autumn.

Calves are able to stand up after birth and should have colostrum from their biological cow within 1 hour. Breastfeed 3-4 times a day for 1-3 days, about each time. Mixed breast milk can be fed from day 4 onwards, with a daily dose equivalent to about 1 8-1 6

On the 7th day, the calves are added to the rack of high-quality grass or soft hay and fodder in the calf pen to practice, and they are allowed to chew and eat freely.

Cattle should be classified at a very early age, as this is the only way to better promote the growth and development of cattle.

There are two ways to wean calves, one is natural weaning, the old cow will wean the calf five months earlier and eight months later, and the old cow will not give the calf to eat. Another method is forced weaning, where the calf is tied with a rope so that it does not stay with the old cow. Or corral the calf and separate it from the old cow.

If the calves are weaned in winter. If you wean naturally, you can just pay a little attention to the calf. Because the old cow will also care about the calf, and if the calf is not in good condition, the old cow will continue to feed it.

Farmers generally do not choose to force the weaning of their calves in the winter because it is difficult to manage. If it is forced weaning, then it must be carefully managed, give the calf essence and grass concentrate, and add a little more intensive feeding department to make the calf eat better. Calves can be given one or two extra meals.

Pay attention to cold and disease prevention, the temperature is low in winter, the calf has just been weaned, the resistance is poor, it is easy to get sick from the cold, we must pay attention to this problem, so that the calf can be warmed in the cowshed, it is best to add some temperature. The calves must be observed more than three times a day, taking care not to make them sick.

Calves are generally fully weaned at the age of 3-4 months is the best, the specific needs to be determined according to factors such as calf constitution and environment, if the calf is poor or the temperature is low in winter, it can be weaned later, and the calf can be weaned earlier if the calf is strong and the temperature is suitable. Weaning the calf too early, the calf's stomach is not fully developed, it is difficult to fully digest and absorb the feed and forage.

First, it is best to wean calves for a few months

1. Calves are generally 3-4 months old and completely weaned at the best time, and the specific needs to be decided according to factors such as calf physique and environment, if the calf has a strong physique and the temperature is suitable, it can be weaned earlier; Calves can be weaned later if they are in poor condition or if the temperature is low in winter. If the calf is weaned too early, the stomach of the calf is not fully developed, it is difficult to completely digest and absorb the feed and forage, and it is difficult to obtain sufficient nutrients required for growth and development, which will affect the normal growth and development and health of the calf.

2. In the process of weaning, the calf should pay attention to let it eat clean and warm water freely, and not cut off the water; The upper limit of milk feeding is taken in winter and the lower limit in summer; Weaning should be combined with time and feed intake, more than 40 days after birth, three consecutive days of feed intake kilograms can be weaned; Weaning and refeeding should not be done at the same time to prevent an over-stress response.

2. Early weaning methods

1. When the calf is born 1-3 days after birth, it is necessary to eat enough colostrum and feed it 3 times a day.

2. On the 4th-7th day of birth, feed 3 kg of regular milk every day and feed it in 4 times.

3. On the 8th-15th day of birth, feed 3-4 kg of regular milk every day, feed it in 4 times, and feed high-quality and easily digestible calf concentrate feed and hay or calf TMR diet from the tenth day, add a little less every day to keep it fresh and train to eat.

4. On the 16th-28th day of birth, feed 3-4 kg of regular milk every day, feed it in 3 times, and feed a kilogram of diet at the same time.

5. On the 29th-41st day of birth, feed 2-3 kg of regular milk every day, feed it in 2 times, and feed kg of diet at the same time.

6. On the 42nd-45th day of birth, 2 kg of milk per day should be fed at one time, and a kg of diet should be fed at the same time.

7. On the 46th day of birth, weaning can be started, and more than 1 kg of ration can be fed every day.

Summary. 1.The lactation of temporal meat cows begins to decline around 2 months post-farrowing, and the lactation at 70 days post-farrowing only meets 80% of the calves' nutritional requirements.

Therefore, feeding the calves with forage at an earlier time for them to practice feeding helps the calves to compensate for the nutritional deficit of their breast milk by digesting the forage. At 3 months of age, calves already have a good feed intake and digestion capacity, and weaning is easier, so this is the right time for early weaning.

Hurry, hurry, hurry. 1.The lactation of female Jane silver cattle for meat meat has begun to decline about 2 months after giving birth, and the milk production at 70 days after giving birth can only meet 80% of the nutritional needs of calves.

Therefore, feeding the calves with forage at an earlier time for them to practice feeding helps the calves to compensate for the nutritional deficiencies of their breast milk by digesting the forage. At the age of 3 months, calves already have a considerable amount of feed intake and digestion of forage, and weaning is easier, so this is the right time for early weaning.

2.Feed requirementsAlthough calves are weaned at the age of 3 months, they have basically been accustomed to picking hay and concentrate diets, but at this time, the rumen is not completely divergent, and at the same time, in order to ensure that the feed intake can meet the needs of the growth and development of calves, the combination of calf diet and roughage must be reasonable. Generally, the ratio of concentrate and roughage is 1 1.

The coarse feed is high-quality hay, grass and silage corn. After 4 months of age, straw feed can be gradually added, generally at 9 months of age, the amount of straw feed should not exceed one-third of all coarse material.

Too much. Brief.

The main requirements for calf diets are easy to digest, clean and hygienic, and pollution-free empty tung. Most of the feed programmes used for female calves are up to 6 months of age and are based on the consumption of 170,225 kg of concentrate. Whether it is mixed concentrate or roughage, the feed amount is gradually increased from less to more.

After early weaning, calves may have a lack of coat color and a sagging abdomen, and some calves are sluggish, inactive, and slow in weight gain, which is due to the lack of adaptation of the calf's forestomach function and microflora due to sudden changes in feed type, coupled with early weaning, and insufficient total nutritional levels of the diet. In general, the above phenomenon disappears quickly as the level of food intake increases. The recommended formula for concentrate is soybean cake 27%, cornmeal 50%, bran 10%, fishmeal 10%, vitamin and mineral additives 3%.

Keep it simple. This is the careful version, and it is responsible for you.

Ah. I don't want you to be responsible for me.

Feed green and juicy feed. Green juicy feed such as carrots.

Beets, etc. Calves are fed at 20 days of age to promote the development of digestive organs. Feed 20 g a day, which can be increased to kilograms at 2 months of age, and 2 to 3 kg at 3 months of age.

Silage can be fed at 100 150 g per day at 2 months of age, kg at 3 months of age, and 4 5 kg of panhu at 4 6 months of age.

With the continuous rise of pork, the demand for beef in the market is getting higher and higher, and for rural areas, the good natural environment and animal husbandry conditions are very suitable for the development of the cattle industry.

At present, the distribution of cattle breeding in China is also getting wider and wider, and there are also high-quality varieties in various places.

And in the process of raising cattle, weaning the calves is a very important job.

So what do you need to pay attention to when weaning? When is the right time to wean? Let's find out.

When should calves be weaned?

In the case of dairy cows, calves are usually weaned at an early stage.

But beef cattle are different from dairy cows in that they don't have to be weaned too early because there is no need to produce milk.

Normally, calves can eat more forage at the age of 3 months, at this time we can choose to wean the calf dust according to the specific situation, such as the calf is poor or the temperature is low in winter, we can wean later, and the calf can be weaned earlier if the calf is strong and the temperature is suitable.

Precautions for weaning calves.

1. Start eating in advance.

Calves need to be fed in advance before weaning, and generally around 10 days of age, they can use fragrant and sweet pellets or concentrates (suckling pig cotter feed) as starter material for gravitation.

After the calf opens, the opening material can be gradually replaced with general concentrate, and the concentrate feed can be increased appropriately with the growth of the calf. Big Shirt.

After the calf reaches the age of 20 days, it can be properly fed some forage, and the green hay feed needs to be provided to promote the rapid development of the rumen, and the calf can be fed after the high-quality alfalfa hay is short and softened with water, and the calf can be supplied with other green hay and gradually increase the supply with the enhancement of the calf's feeding capacity.

2. Weaning method.

Calf weaning can be divided into two methods: one-time weaning and gradual weaning.

One-time weaning is to abruptly separate the calf from the cow, and its square rolling method is direct and simple, but the stress on the calf is relatively large, and it is suitable for larger calves over 5-6 months old.

And 3-4 months old or younger calves are best to choose to be weaned gradually, the specific method is: the calves that need to be weaned are separated from the cow fence, it is best to see each other in the fence, 3 times a day the calf is put into the cow pen for lactation, each lactation time is 1 2 hours is appropriate, and then gradually reduce each lactation time, during which the amount of concentrate and forage must be gradually increased, and the calf is provided with sufficient nutrition, so as to enhance the calf's digestive ability and anti-stress ability.

3. Feeding after weaning.

After weaning, the calves should continue to be fed in rough and intensive feeding before weaning, and gradually increase the amount of intensive feeding as the months of age increase.

When the age of the month is in 3-4 months, the intensive feed should be increased to kilograms per day, and at the same time, high-quality hay should be selected for its free feeding, before the age of 4 months, try to feed less or not feed the green feed, after the age of 4 months, you can change to feed the cattle concentrate feed.

In general, the most common problem during weaning is the stress response, so it is important to have a reasonable grasp of the weaning period, and to provide the calves with nutritious, easy-to-digest concentrate feed and high-quality green hay.

If there is an abnormal situation during the weaning period, it should also be reported to the technician in time and solved.
