Target lactating sows its management are: First, try to increase milk yield, in order to ensure normal growth and development of piglets, the second is to minimize the sow during lactation off fat, to ensure early estrus after weaning.
Milk sow their management objectives are:
First, try to increase milk yield, in order to ensure normal growth and development of piglets, the second is to minimize the sow during lactation off the fat, to ensure early estrus after weaning, concrete must do the following:
1, note the gradual reduction of feed material before and after childbirth, postpartum lactation sows to ensure the gradual rise. Here it must be emphasized too hasty feeding postpartum phenomenon; many farms, sows postnatal day due to not eating and physical exertion, so postpartum intake volume, but excessive intake frail, indigestion, caused by after a few days without food, severe vomiting, thought it was inflammation, even if you can digest, but also prone to mastitis, postpartum fever, diarrhea in piglets and other issues.
2, lactation feed should ensure a high level of energy and protein, focus on quality protein. Fishmeal in feed should add about five percent of the soybean phospholipids fatty feed.
3, succulent green fodder fed properly, adequate supply of drinking water.
4, before and after weaning, sows should be gradually reduced Wei Liang. One week before weaning gradually reduced by 5.0 kg more than 2 kg or 1 kg, weaning day without feeding, so that can make more than feed the piglets feeding particulate material, but will also prevent the occurrence of mastitis after weaning.
Lactating sows feeding requirements: from day 7 after birth onwards, ad libitum, typically: 1.5-l.0 kg 0.5 with the number of hot days in piglets fed 3-4 times a day 2-3 times a day in winter. Avoid: continuous use of antibiotics in pig feed: early feeding, early weaning sows to reduce the burden: the best are weaned at 28-35 days.
