Veterinary Clinical Medicine-I (General and Systemic)

EPIDEMIOLOGY

• Lush young and leaves containing high concentration of soluble protein are dangerous.
• Outbreaks of feedlot bloat are usually of the frothy bloat
• Sporadic: Free gas type and secondary to lesions which cause dysfunction of eructation.

Bloating forages

• Alfalfa, red clover, white clover, young green pasture with high protein content.

Non-bloating forages

• Bloat safe forages contain tannins, which bind with soluble proteins and inhibit microbial digestion
• Grazing very succulent pasture –immature rapidly growing legumes in the pre bloom stage 

Risks

• Herbage at vegetative to prebud stages of growth
• Liberal administration of urea to pasture, high intake of glucose, calcium and magnesium and high nitrogen intake.
• Cool temperature delay the maturation and extend the vegetative growth phase of forage crops and optimize conditions for bloat
• Salivary protein bSP30 is correlated with susceptibility to bloat
