In nature and in old style farms cows were started to lactate by breeding them. The lactation would then continue after birth as long as the cattle were milked. There are, however, cattle with the heredity to be significant milk producers but which exhibit low fertility (don't have calves). These can be induced to produce milk by injections of bovine somatotropin (bST) and then made to increase milk production with injections of estrogen plus progesterone,
Yes. No milk will be produced until it is needed - to feed a calf.
What do you mean "without heat"? Heifers don't require it to be warm or hot outdoors to be able to get bred if that's what you mean. They can be bred when it's cold out too.
No.
Yes
After having their first calf.
This is just like that Chicken or Egg? question that is floating somewheres on WikiAnswers. The obvious answer has to be the calf, since bos Taurus can't have come about without first starting as a calf and going from there.
No. The bull should be separate from the heifer and her calf simply because it's less stress for her and enables her to mother up to her calf without having to be getting after the bull if he tries to interfere with her.
In most circumstances, yes. Calf compression sleeves are designed improve the endurance of the use of the given calf and therefore actually influence the performance.
It's the name for a heifer that has had her first calf and is currently raising her first calf. It's also a name for a heifer that came from a heifer or cow that was that heifer or cow's first calf.
Calf tables don't hurt the calf when they're being flipped over on their sides, unlike what may happen if a person grabs a calf and throws it to the ground instead of letting it gently slide to the ground. They also hold the calf in place without having to have extra hands sitting on or flexing a calf's leg or head to keep it from moving while branding, tagging, castrating and needling is done.
From when?? From when she was last bred, when she had her last calf, when she showed heat after having her calf, or when she was bred after having her last calf?? Please be more specific so the question can actually be answered.
well if your calf muscle constantly twitches you are probably having a muscle spasm
First of all, there is no such thing as an adult calf. A calf is no longer a calf after he/she is weaned. After a calf is weaned, she would be called a heifer. If it's a male, then he would be called a steer (if he's already been castrated) or a bull (if still intact or uncastrated). A heifer becomes a cow after she has had at least two calves. When she has her first calf, she is commonly referred to as a first-calf heifer.
Cow. Calf came after.
This question cannot be answered without knowing the characteristics of the mother, father, and calf.
Most often a calf's mother is referred to as the dam of the calf, or more commonly, a cow. If it's a heifer that has had a calf for the first time, some folks like to call her a first-calf heifer.
