A 3 day old calf should be nursed 3-5 times a day depending on its size and strength.
every day
That all depends on the age and weight of the calf. Typically a calf should recieve 10% of its body weight in milk replacer per day.
Most antibiotics are administered twice a day. You should speak with a vet and pharmacist to be sure your calf is getting the proper dosage.
No. Should be either or. Electrolytes if calf has scours, milk replacer if it's healthy.
As much as they can
depends... did you feed it during that first week?
Baby bunnies nurse from their mother about 1-2 times a day, usually in the early morning and evening.
A hungry calf is a healthy calf. Don't feed a calf too much other wise it will scour. Otherwise, you know a calf is getting enough if you are knowingly keeping on top of regular feedings and watching it grow day by day. A healthy calf is a calf that's not lethargic, sickly-looking and interested in eating.
A calf with only four teeth is a newborn calf, or one that is just a day or two old.
I do 200 squats a day and 200 calf raises
First tie up the mother cow or serrogate mother in a stall or have her in a chute were you can easily access the udder. Hobble her in case she decides to kick. Next, guide the calf to the cow's udder and see if it will try to latch on. If not, open the calf's mouth and at the same time squirt some milk into the calf's mouth to get it to have a taste of it. You may have to put the teat into the calf's mouth and help it suckle by doing the similar thing mentioned previously. If it can't suckle enough to get adequate nutrients (first day after birth is vital the calf gets its colostrum), you will have to tube it orally. It is VERY important that the calf gets its colostrum after birth, otherwise its chances of surviving are very slim, even if the calf is 2 days old. But don't quit, get some electrolytes in it, and powdered colostrum (mixed with water of course.) Good luck!
A calf needs around 2 to 2.5 quarts or 4 to 5 pints of milk per day.
