How are Yak calves weaned?
The yak calves are weaned at the sixth month of age to decrease the separate yak and calf. In case the calf continues to try to suck the milk, a 20 cm piece of cut wood sharpened at both ends is inserted through the nasal septum between the two nostrils.
What do you feed baby calves in a bucket?
Provide a handful of calf starter in a shallow bucket and gradually increase the amount of starter as calves grow. For optimal calf growth and nutrition, feed fresh calf starter and water daily. Calves ranging in age from 1 day to 12 weeks old have different nutritional needs, and calf starter needs are no exception.

Calves ranging in age from 1 day to 12 weeks old have different...
What do baby yaks eat?
Yaks are herbivores, meaning they only eat plants. They spend a great deal of time in mountain meadows, grazing on grasses and other low-lying plants like sedges. Carex, Stipa, and Kobresia are among their favorite grasses. They also consume herbs, winter fat shrubs, moss, and lichen.
What do you feed yaks?
Yak nutritional management is similar to that of most other ruminants: good-quality hay, a clean source of water, and a cattle vitamin and mineral mix will suffice most of the time, while cattle growing or finishing rations will increase meat and milk production.
What do you need to raise a yak?
Yak are generally very hardy and not susceptible to diseases. They are easy keepers and do not test fences, as long as they are happy where they are. They require a salt and mineral block in addition to pasture and supplemental hay in winter.
How much hay does a yak eat per day?
about 15 lbsHow much do they eat? Approximately 1-3% of their body weight per day. Calves consume approximately 3lbs per day and adults about 15 lbs of quality forage or hay per day.
What age do you butcher a yak?
The effect of this cycle is low growth efficiency and low production efficiency for the grassland production system of this plateau, where the standard for marketing and slaughtering of yaks is 5 yr of age or older.
How many acres do you need per yak?
Yaks have nimble hooves that make them light on their feet, keeping them from tearing up the grasslands as much. The do not need more than one or two acres of land. They eat less than cattle and require less work. These beasts of burden can be useful for everything.
Are yaks hard to raise?
They are easy to raise and are well adapted to high altitude and most climates. They eat 1/3 less than cattle and improve the environment. They are disease resistant and do well without antibiotic and steroids.
How much does a baby yak cost?
Their price range is from $2000 to $10,000 each. Most are sold in the $2000 to $3000 range. They represent about 5 to 10% of all yaks in North America. Some "Super Woollies" fall into this category, as a number of breeders have been selecting for both qualities, the black nose and the very hairy look.
Is raising yak profitable?
Raising yaks is no doubt profitable, which is why a lot of livestock farmers are now raising yaks.
What is the lifespan of a yak?
25 yearsLifespan, ageing, and relevant traits The yak reaches full size in 6-8 years. In the wild, these animals have been estimated to live up to 25 years [0434].
Can yaks eat apples?
Food at the Zoo At Riverview Park and Zoo, domestic yak are fed diets consisting of alfalfa, herbivore cubes, apples and carrots.
How much water does a yak drink?
A yak cow will eat one-quarter the amount that a beef cow requires, and drink one-quarter the amount of water, and weighs about 600 pounds (roughly half the weight of a beef cow), making yak herds less destructive of the lands to which they have access.
Are yaks friendly?
Yaks are very friendly in nature and there has been very little documented aggression from yaks towards human beings, although mothers can be extremely protective of their young and will bluff charge if they feel threatened.

Can yaks eat apples?
Food at the Zoo At Riverview Park and Zoo, domestic yak are fed diets consisting of alfalfa, herbivore cubes, apples and carrots.
What does yak meat taste like?
Yak tastes a bit like bison, but it's a much deeper red thanks to higher hemoglobin in yaks' blood cells. The animals, built for high-altitude environments with less oxygen, also have up to three more ribs and a larger lung capacity than cattle.
What do yaks need?
Yaks Need a Quality Diet. Yak nutritional management is similar to that of most other ruminants: good-quality hay, a clean source of water, and a cattle vitamin and mineral mix will suffice most of the time, while cattle growing or finishing rations will increase meat and milk production.
What is a yak?
The yak is a diverse species, providing its keepers with meat, fiber and milk, and with training, can also act as a talented draft animal. Although kept similarly to cattle, there are a few key difference you need to keep in mind before adding one to your farm. Here’s what you need to know.
How long do yaks live?
While yaks can generally be managed like cattle, they live longer—up to 30 years —and have slower growth rates. They’re also both browsers and grazers, while cattle are grazing-focused with minimal to no browsing. 2. Yaks Need Shelter.
Is yak a cattle disease?
6. Yaks Are Prone to Cattle Diseases. Yaks are generally susceptible to most common cattle diseases. Each region of the country has specific endemic diseases, and a few diseases are prevalent nationwide.
Do yaks need shelter?
Yaks Need Shelter. Yaks have evolved to handle extreme environmental conditions, such as low temperatures and high altitude, but they can thrive in more temperate regions with proper care and management. In warmer regions, an open overhead shade will improve the comfort of the animal.
Is a yak a good animal?
Yaks are Good-Natured. Yaks are enjoyable animals to work with. Quality genetics are the foundation to good temperament, as are positive and patient handling and good husbandry practices. In my experience, the yak-cattle crossbreed tends to lose the gentle temperament.
How do yaks survive?
In most herds, only very weak animals and some pregnant or lactating yak are given access to feeds in addition to grazing. Low calving and growth rates are attributed to the poor nutritional condition of the yak, in the cold season particularly. The traditional way of maintaining the animals is to allow them to put on as much fat as possible during the warm season; fat that is then used over the long cold season as an energy reserve to allow survival beyond the early spring. The tragedy of large numbers of animals dying because of snow disasters is frequent on the Qinghai-Tibetan Plateau. Nowadays, the yak population is increasing rapidly, causing rangeland degradation and, hence, further increasing the gap between feed supply from natural pastures and the animals' feed demand. Thus, the malnutrition that the yak has to suffer is likely to become worse in the foreseeable future. A good understanding of yak nutrition under grazing conditions, which could help to alleviate some of the problems, is still rather inadequate. But this chapter provides some of the evidence that is accumulating and points to several gaps in understanding and the need for validation of some of the preliminary findings.
Why do yaks eat less?
Generally, yak consume less feed than other cattle, probably because of their smaller rumen capacity. Yak prefer fresh, high-quality forages, and both housing and high temperature can reduce feed intakes. Dry matter intake (DMI, kg per day) of the growing yak under indoor feeding can be estimated as DMI = 0.0165 W + 0.0486 (W is body weight in kilograms), and that of the lactating yak as DMI = 0.008W 0.52 + 1.369Y (W 0.52 is metabolic body weight, Y is milk yield, kg per day).
How does yak diet affect DMI?
Han et al. (1990a) fed castrated yak (two to three years old) in barns seven diets and found that the dry-matter intake (DMI ) of roughage decreased with the increasing content of concentrates in the diets (Table 14.1). Dong et al. (2000a) studied the digestion and metabolism of protein and energy in lactating yak given different diets and found that concentrates in the diets decreased the DMI of yak. Preference for fibrous feeds may result in higher intakes of roughages than of concentrates by yak, and a relatively faster passage of high-quality roughage (such as oat hay) leads to reduced mean retention time of digesta (Han, 1996) and thus results in higher intake. In both studies, the authors stated that the intakes of yak were less than those of other cattle, possibly because of the smaller rumen capacity of yak (Liu, 1991).
What is the DMI of a yak?
Liu et al. (1997) reported that the DMI of two-year-old yak (as a percentage of body weight) varied from 3.7 percent in the late growing period of forages to 3.4 percent in the mature period under grazing conditions, while that of three-year-olds ranged from 3.7 percent to 3.1 percent. Feed intake per unit of body weight under grazing was greater than in the indoor feeding. Possibly unsuitable housing and restriction to a given diet may be the main factors that reduced the feed intake of the indoor-fed yak.
What is the respiratory rate of yak?
Hu (1994) suggested that the respiratory quotient (RQ) of the growing yak determined by metabolism significantly declined with increasing altitude, from 0.744 (2 261 m) to 0.696 (3 250 m) and 0.545 (4 272 m). But with no significant difference among age groups, the values less than 0.7 indicate disordered metabolism (perhaps ketosis). Lower atmospheric pressure and oxygen contents in the air at higher altitudes may be the main factors that lead to reductions in the respiratory quotient of growing yak. Corresponding information from other species would be interesting but appears not to be available. Hu (1994) also indicated that ambient temperature has a great effect on FHP and other physiological indices in the yak (see Tables 14.9 and 14.10). But the FHP remained fairly constant and, correspondingly, the body temperature, heart rate and respiratory rate of yak were stable in the environmental temperature range of 8° - 14°C. So the thermoneutral zone of the yak was estimated as 8° - 14°C (see Chapter 4).
How does temperature affect yak?
Climatic factors, especially temperature, have a profound effect on feed intake and digestibility in the yak. Growing yak increased their intake levels at lower temperatures irrespective of whether they were feeding indoors (Han et al., 1990a) or grazing on natural pasture. The faster rate of passage of feed particles at lower temperatures (Liu et al ., 1997) would provide more rumen space to be filled by food.
What are the factors that affect ruminants' feeding strategy?
For ruminants, a number of factors, including gastrointestinal size and capacity, rumen fill, rumination, digestive capacity, absorptive gut surface and quality of available forage affect feeding strategy (Van Soest, 1987). Yak, standing apart from other ruminants, have their own rumen characteristics and digestive capacity under different feeding strategies.
How to feed calf starter?
For optimal calf growth and nutrition, feed fresh calf starter and water daily. Calves ranging in age from 1 day to 12 weeks old have different nutritional needs, and calf starter needs are no exception.
How old do calfs need starter?
Eight to 12 weeks old. As calves continue to grow, calf starter consumption increases significantly. Don’t limit intake at this stage of development and don’t allow calves to go periods of time without calf starter. Once calves reach 12 weeks old, introduce a calf grower feed.
Can you eat stale calf starter?
Stale calf starter may look ok to eat but may not be palatable. To put it into human perspective, compare stale feed to a cracker that has been left out for a day or two. It may look just like the crackers left in the package but doesn’t taste fresh and crisp.
Overview
Management systems for yak predominantly follow a traditional pattern dictated by the climate and seasons, by the topography of the land and by social and cultural influences. Methods of keeping the yak vary from the primitive, where herds are allowed to roam virtually at will, to the technologically advanced.
Introduction
There is no single management system that applies to all yak over the large area of its distribution. Methods differ according to country and region, influenced by altitude, climate and topography. There are differences in management related to culture and religion.
Herdsmen's activities according to seasonal cycle
Early summer: Supervising births and protecting calves; adjusting and subdividing the herd; castrating.
Yak pastures and grazing habits
A full description of the rangeland and the plant species and their distribution will be found in Chapter 13. Only those aspects that reflect directly on the management of the yak are discussed here.
Yak herd management
Before the Household Responsibility system was implemented in yak territories of China, both the animals and the grassland belonged to the State. In those circumstances, the total yak herd, as merged from the animals of several families and one or more villages, was usually divided into component herds.
Equipment and penning
Generally, there is little equipment to assist the herdsmen in the management of yak on range.
Management of yak herds on the range
Temperamentally, yak are at varying times wild or timid, cowardly and yet aggressive. Another part of the yak's character is its strong herding instinct. All these aspects have to be taken into account in training yak to obey commands so that a single person can control and manage a large herd.
When is yak calving season?
In the summer season, grazing is usually at a higher altitude. Therefore, farmers are generally far from home this season. June, July, is the yak calving season when high-quality forage is available in sufficient quantity. In this season, yaks restore weight loss and can gain weight due to good nutritional forage.
How much does a yak weigh?
Its weight ranges from 350 to 550 kg in the case of males, while the weight of females ranges from 225 to 255 kg. Wild yaks can reach up to 1000 kg. Yaks do not make moaning sounds like other cattle do. They often grunt like their scientific name “Bos grunniens,” the grunting bull.
What is the scientific name for yaks?
The word yak is used for both sexes for bull and cow. The scientific name for a domesticated yak is “Bos grunniens” used by Linnaeus in 1766 for the first time. The word Bos in a scientific name indicates that yaks and cattle belong to the same genus. The term Bos grunniens is only used for domesticated yaks, for wild species Bos mutes is preferred.
How long do yaks live?
Yak management is related to livestock management. The useful life of yaks is much longer than that of cows. They can live up to 30 years, but their growth rate is very slow compared to cattle. Yaks are herbivores and browsers.
Why do yaks lose weight?
In this season, the yaks lose weight due to the poor quality and quantity of forage in the grasslands.
Why are yaks thick?
The thick layer of yaks serves the purpose and binds extreme environmental conditions such as high altitude with low temperature. They can be handled in temperate areas with proper handling and care.
What is the color of a yak?
The color of the wild yak is generally black to brown, while the domesticated yak is different in color in different areas. Yaks have dark horns on his broad forehead.
How to care for a bottle calf?
The first priority in caring for a bottle calf is to ensure adequate colostrums intake. Fresh colostrums from the mother are the best and may require restraining and milking the mother or allowing the calf to nurse the restraining mother. This can be accomplished in a squeeze chute with removable sides that allow access to the udder.
How Can We Guide a Newly Born Calf about Feeding the Milk with the Bottle?
Although a calf may instinctively nurse its mother, it may need to be taught to drink from a bottle. Start by inserting one or two fingers into the calf’s mouth.
How to make milk replacer more attractive to calf?
Mix milk replacer with warm water to better dissolve the product and make it more attractive to the calf. Keep the temperature of the mix consistent between feeding and not more than 100 degrees Fahrenheit. Also, use the same amount of milk replacer in the mix each feeding.
What is milk replacer powder?
Milk replacer powders are reconstituted with warm water and make an excellent and oftentimes economical liquid feed for baby calves. Especially during the first three weeks of life, calves should be fed a milk replacer that contains all milk proteins made from dried skim milk or whey products. Whey products can include whey protein concentrates, dried whey, and lactose whey.
How long do calves need milk?
For the first two weeks of life, calves receive most of their nutrition from milk. From four days of age, calves can be fed either whole milk, waste milk, reconstituted milk replacer, or fermented or fresh colostrums. The type of milk-fed is determined by price, availability, and convenience.
What milk should be used to prevent John's disease?
To prevent the spread of Johne’s disease to young calves, colostrum, fermented colostrum, whole milk, or waste milk should be obtained from cows testing negative for john’s disease.
What is a cow's calf called?
In the dairy industry, calves are routinely separated from their mothers at very young ages. The resulting calves are sometimes referred to as “bucker” or “ bottle” calf.
How many bottles of water do calves need?
Most calves need only need 2–3 bottles a day. You won’t have to worry about middle-of-the-night feedings or early-morning waking; bottle calves eat during the day and sleep at night.
What to do if you suspect calf scouring?
If you suspect calf scouring in your herd, contact your veterinarian. Scours can be dangerous for calves (especially very young ones) and need to be treated.
Can bottle calves be fatal?
This condition is dangerous and can be fatal. Be sure to watch your bottle calves closely (especially their stool) to be sure everyone is healthy. If your bottle calf has access to a lactating dairy cow, they could face a higher probability of overfeeding. Some mama cows will be happy to “adopt” your new calf.
Can you bottle feed an orphan calf?
Some have been separated from mama so the dairy can have the milk. There are calves everywhere looking for good homes. If you find yourself face-to-face with an orphan calf, you may want to say, “YES!” to the little fellow. Why You Should Consider a Bottle Calf: Bottle feeding is a great way to start your own herd.
Is a bottle baby calf cute?
There are few things as adorable as a bottle baby...a bottle baby calf, that is. It is hard to find a cow as sweet, affectionate and people loving as a former bottle calf. The little critters are hand-raised, loved and sometimes feel more like the family dog than the family heffer. If they weren’t so big and bouncy, ...
Do calves need to run after feeding?
The calves are just as adorable, grateful and spunky, but I am not as enthusiastic about the whole thing. This is why you may need to run after feeding them their bottle. As soon as our calves finish their bottles, they immediately start looking for an udder.
Can a mama cow adopt a calf?
Even when our calves are being well fed (three bottles a day), they may still run to the milk cows in search of a free meal. Don’t count on a full belly to tell your little one to stop eating. Manna Pro has a NEW product that supports digestive upset: Calf Care™.
