What to do when the pub has no beer. Or milk.
Sometimes mother’s milk is not available. The mare cannot provide for the foal and there is no readily obtainable source. Perhaps a nurse mare is not accessible or not affordable. As replacers are more concentrated than mare milk, correct dilution with water is essential. Dry matter percentage at final dilution should attempt to match that of mare’s milk at approximately 10-15%. 1 This may differ from the targeted concentration of the milk replacer. Make sure you calculate well. Increased osmolality (concentration) of milk replacer as compared to mare milk may lead to constipation, hypernatremia (elevated sodium concentrations in the blood), and dehydration in the compromised foal. Additionally, the higher osmolality of the milk replacer may induce an osmotic diarrhea (concentrated ingesta draws water into the gut). Bovine-based milk replacers contain sugars not normally found in mare’s milk or in different quantities. Thi...
