The period from calving until normal dry food feeding is very sensitive for preruminat animals. Normal weaning can be successful at 6 to 8 weeks post partum. Young milking calves are very susceptible to bacterial or viral infection if immunity is not reached through colostrum on time. On the other hand indigestions are very frequent and account for one-third of the most frequent disorders in young calves. Parturition losses (dystocia) and respiratory diseases are more frequent. The final result of negative environmental and management influences can be the onset of acute or chronic diarrhea associated with long, expensive and often unsuccessful treatment. Acute dehydration and death are not so rare. Etiological reasons are known, it is possible define them: inadequate feeding of pregnant cows and heifers in late stages of pregnancy; hygiene problems and bad management of neonate calves. Contaminated milk, starters and milk substitutes are the main source of scours. These problems are evident on farms where owners or workers do not have the elementary knowledge about physiology, anatomic differences and management principles for preruminant animals. At weaning time calves can develop serious problems when dry feeding does not begin on time. For does that reason normal micro flora and fauna are not able to accept normal function for ruminal digestion.
