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

A Country I would like to visit

A place I would like to visit

that place could be madagascar

I would like to travel to Madagascar because I think it’s such a beautiful place, with so much fauna and flora

What I know about this place,

 is the fourth-largest island in the world, following the prehistoric breakup of the supercontinent gondwana, Madagascar split from india around 88 million years ago, allowing native plants and animal to evolve in relative isolation so madagascar’s fauna is diverse and exhibits a high rate of endemism, is a biodiversity hotspot

I would like to know the different places, watch the environment look at the, learn about

That culture, Each of the many ethnic sub-groups in Madagascar adhere to their own set of beliefs, practices and ways of life that have historically contributed to their unique identities. However, there are a number of core cultural features that are common throughout the island, creating a strongly unified Malagasy cultural identity, it would be very interesting learn about them

But unfortunately Madagascar's varied fauna and flora are endangered by human activity

Since the arrival of humans around 2,350 years ago, Madagascar has lost more than 90 percent of its original forest, if the deforestation continues at that rate probably everything would disappear
