Sudden death cause in cattle
There are various causes, including:

Respiratory Diseases: Similar to cattle, respiratory diseases like pneumonia or bovine respiratory disease complex (BRD) can lead to sudden death in heifers if not treated promptly.

Cardiac Issues: Heart-related problems such as congenital defects, myocarditis, or heart failure can result in sudden myocard
Digestive Disorders: Acute conditions like bloat, twisted stomach (volvulus), or severe cases of gastrointestinal issues can lead to sudden death if not managed promptly.

Metabolic Disorders: Conditions like milk fever (hypocalcemia) or ketosis can cause sudden death if left untreated.

Toxicity: Ingestion of toxic plants, chemicals, or contaminated feed can result in sudden death.

Trauma: Severe injuries from accidents, fights, or mishandling can lead to sudden death.

Heat Stress: Extreme heat can cause heatstroke or dehydration, leading to sudden death if not mitigated.

Reproductive Issues: Complications during calving or pregnancy, such as uterine torsion or prolapse, can result in sudden death.

Identifying and addressing the underlying cause promptly is crucial in preventing sudden death in heifers. Regular monitoring, proper nutrition, vaccination, and appropriate management practices are essential for maintaining heifer health and reducing the risk of sudden death.

Cow Mastitis causes, prevention and treatments

Bovine mastitis is a condition typified by the persistent and inflammatory reaction of the udder tissue due to either physical trauma or infections caused by microorganisms. It is a potentially fatal mammary gland infection, that is most common in dairy cattle worldwide. It is a disease that is known to cause the greatest loss to the dairy industry.

Causes
There is a large cohort of microorganism species that are known to cause mastitis. These range from virus, mycoplasma, fungus and bacteria.
Bacterial organisms known to cause mastitis are Pasteurella multocida, Staphylococcus aureus; Str. Zooepidemicus; Str. agalactiae; Str. pyogenes; Str. faecalis; Mycobacterium bovis; Klebsiella spp; Brucella abortus; Pseudomonas pyocyaneus; E.coli; Leptospira Pomona, etc.
Fungal entities responsible for mastitis are Aspergillus fumigatus; A.midulus; Candida spp; Trichosporon spp, etc.
Physical injury to the mammary region, poor hygiene and/or trauma, also cause this condition.

Symptoms
The clear sign of mastitis is inflammation of the udder that turns into a red and hard mass. The swollen mammary gland is hot and the mere touching causes pain and discomfort to the animal. Animals do not allow touching of the udder even kicking to prevent milking. If milked the milk is usually tainted with blood clots, foul smelling brown discharge and milk clots.
The milk yield totally stops or is severely restricted. Body temperature of the animal increases. Other symptoms are lack of appetite, hindrance in mobility due to swollen udder and pain. The dairy animal develops sunken eyes, suffers from digestive disorders and diarrhoea.
Infected cattle are severely dehydrated and suffer from weight loss. In cases of severe infection there is formation of pus in the infected udder. Mastitis can degenerate to Toxaemia or Bacteraemia and even cause death as a result of acute infection.
Mastitis can be detected at an early stage (sub clinical) before the symptoms appear, through California Mastitis Test (CMT). It is a quick test that can be performed on small milk samples. Early detection helps in preventing the progress of disease into clinical stages and causing heavy losses to dairy.
