Retained placenta in cattle 

Definition: Failure to expel the foetal membranes within 12 to 24 h after calving.

Delayed placental separation predisposes cows to acute puerperium metritis and endometritis post partum through:

·         increased bacterial multiplication in the uterus

·         impairment of immune function of endometrial macrophages and neutrophiles by bacterial endotoxins

Cystic ovarian disease (COD) in cattle

Cystic Ovarian Disease (COD) and follicular persistency can be described as an Anovulatory condition with Follicle Growth to Ovulatory or Larger Size of Follicle.

Mastitis in dairy cattle

is the persistent, inflammatory reaction of the udder tissue.

Mastitis occurs when white blood cells (leukocytes), are released into the mammary gland, usually in response to an invasion of bacteria of the teat canal. Milk-secreting tissue, and various ducts throughout the mammary gland are damaged due to toxins by the bacteria. Mastitis can also occur as a result of chemical, mechanical, or thermal injury. The udder sac is hard, tight, and firm.

Subclinical ketosis

is defined as high serum ketone body concentrations without observed clinical signs.

Subclinical ketosis causes delayed reproductive functions return to normal after calving, increased intervals from calving to first and last service, and an increased frequency of ovarian cyst

Hepatic lipidosis 

is a major metabolic disorder of many dairy cows in early lactation and is associated with decreased health status and reproductive performance. In severe cases, milk production and feed intake are decreased. Fatty liver develops when the hepatic uptake of lipids exceeds the oxidation and secretion of lipids by the liver, which usually is preceded by high concentrations of plasma NEFA mobilized from adipose tissue.

I like this page because it talk’s about a sanctuary that protect pigs, help them and give them a natural life , and show the other side of pigs, Pigs are intelligent, gregarious, greedy and hedonistic, show the pig more like a pet than a piece of meet, so I like that
