Feed management of early weaned piglets
Weaning at an early age is the practice of greater stress in the pig production cycle and its effects are considered to be multifactorial, summing up behavioural, environmental, health, immunological and nutritional aspects. In relation to its immune defence, the piglet loses the beneficial actions conferred by milk and has altered its passive immunity and its flora, which until then is practically unharmed. From then on it becomes more susceptible to diseases (E. coli, Rotavirus, Salmonella, dysentery, Haemophilus etc.). In addition to this set of undesirable situations, the new nutritional challenge is established, when the young pig will receive a different food to the infant stage. As for nutritional care, the new post-weaning diet should be prepared to take into account the suckling phase of the piglet, when it suckled about 16 to 20 times a day. The post-weaning diet, therefore, must be prepared with ingredients that become compatible substrates to the physiological situations imposed by the management of anticipated weaning. Failure to observe these aspects and the use of incompatible food can compromise the growth of the pig. The reduction in age at weaning coincided with the maintenance of diets based on corn and soybean meal in piglets after weaning. A period that also emphasized the massive use of soy and its derivatives as alternatives to replace sow milk, a highly digestible and pro-infant food. This substitution suggested in several studies occurred, in large part, surrounded by mistakes, since soybeans predispose the piglet to physiological digestive problems, with negative implications for performance.
