Ultimately, because dairy production was already a management intensive industry the disadvantages are dwarfed by the advantages of the AI for many dairy producers. [20] The majority of cows carry a single calf. Pregnancy lasts an average of 280 to 285 days or a little less than 9 and one half months. [19]
In the early stages of the non-lactating period (between 12 and 24 hours) there is decrease of milk protein and cell survival genes, resulting in a loss of epithelial cells. [5] The change in intracellular processes and gene regulation causes a decrease in milk production until all milk production from mammary epithelial cells cease. [5]
Dairy cattle (also called dairy cows) are cattle bred with the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species Bos taurus. [1] Historically, little distinction was made between dairy cattle and beef cattle, with the same stock often being used for both meat and milk ...
Dairy cows need to produce one calf each year in order to remain in milk production. Heifer (female) calves will nearly always become a replacement dairy cow. Some dairy heifers grow up to be mothers of beef cattle. Male dairy calves are generally reared for beef or veal; relatively few are kept for use as breeding stock.
Dairy cattle are usually kept on specialized dairy farms designed for milk production. Most cows are milked twice per day, with milk processed at a dairy, which may be onsite at the farm or the milk may be shipped to a dairy plant for eventual sale of a dairy product. [104]
Cattle bred specifically for milk production are called milking or dairy cattle; [1] a cow kept to provide milk for one family may be called a family cow or a milker. A fresh cow is a dairy term for a cow (or a first-calf heifer in few regions) who has recently given birth, or "freshened." The adjective applying to cattle in general is usually ...
This is most evident with the nipples closest to her hind legs. They will grow larger and pinker. About two weeks after conception, the nipples begin to expand in preparation for milk production ...
In most cases the bovine vaginal prolapse occurs near the time of calving, [1] yet there are some examples of the vaginal prolapse in younger and non-pregnant animals. [2] Another, but less common [1] and more severe [3] reproductive prolapse in cattle is so-called bovine uterine prolapse, where a uterus is the one being abnormally positioned. [4]
