Introduction Calves can be ready for weaning by 3 to 4 weeks of age; however, in Penn State studies calves weaned at 3 weeks required extra attention. The increased time and labor required to get these calves eating starter suggest that waiting until 4 weeks of age would be prudent.

Weaning beef calves Calves are generally weaned between 8-10 months of age. The actual age depends on several factors: 1  Feed availability-cows can continue lactation without losing condition in good years, but early weaning should be considered in drier years.

- Calves should then be used to dry feed upon weaning. Calves will consume 2.5 per cent to 3.0 per cent of their body weight in dry feed each day. Begin creep feeding at least four weeks prior to weaning to minimize stress and allow calves to be adjusted to solid feed.

- There are many research studies that have examined the results of weaning at an earlier age-as early as 30 days of age but usually 150-170 days of age-on the subsequent performance of cows and calves.

- Calves should be completely weaned off milk at 8-10 weeks. It is a good idea to increase their interest in grass and concentrates. Calves must have water. Calves will begin to drink water between their feeds of milk from one to two weeks of age.Lack of water will cause the death of a calf faster than the lack of any other nutrient. By six weeks of age, a calf may be drinking abut four litres of water per day.Only clean, fresh drinking water must be given.igure 4. The calf s first feed of colostrum is essential within five hours of birth For the first couple of days the calf can stickle the cow as and when it wants. During this time the colostrum (which is the first milk) is not suitable for human consumption and should not be sold.

- 1 Consider removing horns and castrating all male calves in commercial operations within the first two weeks of birth. 2  If not weaned at birth, then at least four weeks prior to weaning reduce calf and operator stress by:  vaccinating and dehorning calves while they are still with their mother.

Bottle-raise a calf Weaning the calf. You will be bottle feeding the calf, two quarts a day, for about six weeks. During this time, offer clean hay, pasture or cut grass and clover, fresh calf grain twice a day, and plenty of clean water. At first, the calf will only nibble on the grass, hay, and grain. But after a few weeks, it will eat in earnest.

Introduction Calves can be ready for weaning by 3 to 4 weeks of age; however, in Penn State studies calves weaned at 3 weeks required extra attention. The increased time and labor required to get these calves eating starter suggest that waiting until 4 weeks of age would be prudent.n two experiments, 124 male and female calves were weaned at 3, 4, 5, or 6 weeks of age and studied through 8 weeks of age. Milk replacer for this study contained 22 percent protein and 15 percent fat and was fed at 10 percent of birth weight.

- Some people feed the calves while others just wean them on pasture. Calves 4-5 months of age transition better, as they’re used to eating forage. Younger calves are trickier, but if you can meet the nutrient requirements of calves just 2-3 months old, they can be successfully weaned that young, Lardy adds.alves 4-5 months of age transition better, as they’re used to eating forage.

Calf Rearing Systems For Once A Day feeding feed calf milk replacer at 200gms made up to one litre with water or at 50gms -100gms made up to one litre with whole milk. Feed at 3 litres to supply 600gms of powder, from 7 days to 7 weeks of age. Then reduce by 0.5 litres per day to wean at 8 weeks.

- Weaning process often takes 6 to 8 weeks for the calf and cow to completely be weaned from each other, no matter if you are separating the cow and calf so they don't hear or see each other, using fenceline weaning, nose-ring weaning, or doing natural weaning by letting the cow decide when to kick off her calf.rovide a bucket of water. If the calf eats grain you can wean it as early as 2 months, but three months is better and even later if it is really cold. You can stop feeding milk all of a sudden for older calves that eat a lot of grain, or feed milk only once a day for a while, or reduce each feeding.

The increased time and labor required to get these calves eating starter suggest that waiting until 4 weeks of age would be prudent.eaning at 30 days saved $13 compared to weaning at 45 days. If we use 2007 milk replacer costs in this analysis, we see that weaning at 4 weeks may save as much as $55 per calf over 8-week weaning. Weaning at 45 days will save up to $30 per calf over 60 days.

Steer Planet - Show Steers and Club Calves Forum Re: Weaning Feeder Calves at 3 months old? « Reply #6 on: August 16, 2012, 07:57:30 AM » I think what ZNT is getting at, and I am making an assumption which we all know what happens when we do this, is the fact that, after a certain time frame, the calf is inefficient at gaining off the cow.

- Weaning an orphan calf that you have raised and nurtured for the past few months can be and emotional strain on both you and the calf. The calf will complain a fair bit during the weaning process but you must be diligent and stubborn. 1  Bottle calves should be weaned by the time they are around 3 to 4 months of age.

Early Weaning Beef Calves By the time calves are 3 to 4 months of age, they are consuming significant amounts of forage. At 6 to 7 months of age, calves will consume approximately half the amount of forage as a mature cow. Following weaning, dry cows will eat less forage than lactating cows, further reducing demand placed on the pasture.

- In the two-step weaning process, calves and cows remain together during weaning to reduce the stress of separation. 1  Step 1 - Clip a reusable plastic anti-sucking device into a calf's nostrils (without piercing the septum).  Step 2 - Separate calves from the cows and remove the plastic anti-sucking devices.

When to Wean Cattle NCSU recommends early weaning at 6 weeks of age, as long as the calf consumes the proper amount of calf feed. This starter feed should contain 18 to 22 percent crude protein and consist of 80 percent total digestible nutrients. calf can't be weaned, technically meaning eating only solid foods, until the rumen reaches a certain stage. If you're bottle-feeding an orphan calf, the earliest you could wean the animal is approximately 4 weeks of age.

- 8 percent of the calf's body weigpt in pounds of milk during the first 2 to 3 weeks and then gradually reduce the quantity until the calf is weaned at 4 to 8 weeks. Feeding a set level of 1 gallon per day for Holstein calves until a week or so before weaning has worked fairly well. In no case should the calf be weaned un­

- In Step method, calves are fed different amounts of milk according to age so that milk intake increases up to 20% of the calf’s body weight (calves are fed up to 2.5 gallons of milk) in the first 30 days of age (pre-Step).hen, milk intake slowly declines after 30 days of age to basically no milk being fed at 60 days (post-Step), when calves are weaned. Ad libitum milk feeding provides an unlimited amount of milk during a specific time. For example, calves have free access to milk for 30 to 40 minutes twice daily.

The Impact of Weaning Calves Calves can be weaned any time after their rumens become functional, that is, when their digestive system can process whole feeds. Bottle-fed calves can be weaned after one month of age, while calves nursing cows are weaned between 3 and 8 months of age. It is usually best to wean at the older age. For comparing weight of calves weaned at different ages, a 205-day weaning weight is sometimes calculated. This “205-day WW” is the calf weight adjusted for birth date and weaning date, and does not infer that calves should necessarily be weaned at that age.
