Typical milk fever posture; cow in sternal recumbency with its head tucked into its flank. Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle [1] but also seen in beef cattle and non-bovine domesticated animals, [2] characterized by reduced blood calcium levels (hypocalcemia).
Congenital contractural arachnodactyly (CA), also known as fawn calf syndrome, is an autosomal recessive genetic disorder in cattle. [1] The disorder affects the connective tissue of muscles, [ 1 ] leading to contracture of the upper limb (most obvious in the hind limbs), and laxity of the joints of the lower limbs. [ 2 ]
To reduce the risk, cows are returned to a standing position and encouraged to move around as soon as possible after calving. This is especially important in cases where a calf is pulled to assist the mother. When the cow stands, the uterus normally drops back into the abdominal cavity, which straightens out the uterine horns. [5]
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 bovine. The terms bull, cow and calf are also used by extension to denote the sex or age of other large animals, including whales, hippopotamus, camels, elk and elephants.

As the head of the calf comes out of the vulva, the rest of the body hidden inside the mother creates the strange illusion of a cow with two heads. 5. Lying cow.
This dry period is a critical part of their lactation cycle and is important for the cows health, the newborn calf and future milk production, as it allows the cow time to rest, eat and prepare for birth. During this time, the cow will produce colostrum for the newly born calf. Research has shown that this period impacts overall milk production ...
The virus causes two different profiles of Schmallenberg: Fever of short duration, diarrhoea and reduced production of milk in cows; These disease signs have occurred during the period when the disease vectors (mosquitos, sandflies, midges) are active, during the summer and autumn of 2011, mainly affecting cattle.
Cows are at their most fertile between 60 and 80 days after calving. Cows remaining "open" (not with calf) after this period become increasingly difficult to breed, which may be due to poor health. Failure to expel the afterbirth from a previous pregnancy, luteal cysts, or metritis, an infection of the uterus, are common causes of infertility
