Mother-family lactating period (lactation period) is generally from 5 to 6 months, from the perspective of the whole group, sustainable 2 to 3 months. The central task of this period of feeding and management is to ensure that Tsai's survival and normal growth and development.
In the ration arrangement, the maternal pupa at lactation period must not feed crickets for feeds with full nutritional value, fresh quality, strong palatability, easy to digest, spoilage or suspected quality problems. Feed varieties should be diversified as much as possible, but the main varieties of feed should be relatively stable, and do not change easily to achieve the purpose of nutritional balance and ensure the nutritional needs of pregnant females. In order for the mother's cockroach to secrete enough milk, an appropriate amount of dairy products such as milk, goat's milk, and milk powder can be added to the diet, and some milk or egg feeds can also be fed to facilitate lactation.
Feed processing must be refined during this period, and feed should be made thinner. Do not control the number of foods given, depending on the number of larvae in the litter and the size of the larvae. Aberdeen is more and more, when the age is large, it is necessary to give more food, let them eat freely, and eat as much as possible. When the Aberdeen has been able to eat or when breast milk is insufficient, supplemental feeding should be done in time. The method is to finely grind fresh animal feed, add a small amount of grain feed, dairy or egg feed, and then feed it to Aberdeen. With the acceleration of growth and development of Aberdeen, the amount of supplemental feed gradually increased and the feed transition to the rearing period. At the age of 45-60 days, most of the larvae can feed on their own, and weaning can be carried out one after another to enter the rearing period of young larvae.
The focus of lactation management during farrowing is to strengthen the care of farrowing mothers, because the health of the young is to be cared for by the mothers. Therefore, raising the lactating capacity of the females and creating the appropriate environmental conditions for nursing mothers is Focus on work. On the basis of strengthening day-to-day management, it is flexible to carry out a series of work to keep pigs alive to ensure maximum survival.
