What level of IgG/L is considered quality colostrum?
> 50g IgG/L
At what age does calf scours typically occur?
In calves less than 30 days of age
What clinical signs are associated with calf scours?
Acute, profuse watery diarrhea, progressive dehydration, and acidosis
What can happen if calf scours goes untreated?
Death
What pathogens are responsible for causing calf scours?
E. coli, rotavirus, coronavirus, and cryptosporidium
What components are important in determining sepsis scores?
Failure of passive transfer, level of dehydration, attitude, diarrhea, scleral injection, and localized infection
What can be used to estimate dehydration in a calf?
Degree eyeball recession, skin tent duration, mucous membrane appearance and CRT, changes in body weight, and urine production
What signs are indicative of metabolic acidosis?
CNS depression, weakness, ataxia, and reduced suckle
What are the mechanisms of HCO3 loss in calves?
Fecal loss, severe dehydration and reduced GFR, and unidentified organic acids
What does a sluggish or absent palpebral reflex suggest in a calf?
There is D-lactate acidosis
What are the goals of treating calf diarrhea?
Correct free water and electrolyte abnormalities, correct acid-base deficits, provide nutritional support, and eliminate and/or prevent bacteremia
What are the important factors/requirements of oral electrolyte solutions?
Provide enough sodium to normalize ECF volume, facilitate absorption of Na+/water, contain alkalinizing agent, and provide energy
What electrolyte is the principle determinant of ECF volume?
Sodium
What is the recommended concentration of sodium in oral solutions?
90-130 mmol/L
What is the recommended concentration of chloride in oral solutions?
40-80 mmol/L
What is the recommended concentration of potassium in oral solutions?
10-30 mmol/L
What other substances are in oral electrolyte solutions?
It can have glucose, neutral amino acids, and volatile fatty acids
What is the osmolality of most oral electrolyte fluids?
280-300 mOsm/L
What is the osmolality of hypertonic solutions?
700-800 mOsm/L
When would you want to use a high osmolality solution (like hypertonic saline)?
In cases of osmotic diarrhea, slow abomasal emptying, ileus, bloat, and abomasitis
What do we need to provide in our acidotic agents?
An alkalinizing agent
