In Europe, a suckling sow can feed more than 8kg per head, and the feed intake in our country is often less than 5kg. How to increase the feed intake during lactation is a major issue. The following methods are available for reference.
1. Pre-pregnancy and gilts use the high-grain formula that we provide, and the feed intake should not be too high, otherwise the gut will not develop well during the lactation and the sows will not eat.
2, 0 to 7 days after delivery, food intake gradually increased, but can not increase too fast, or the amount of milk exceeds the need for piglets, but affect the secretion of prolactin, and reduce the amount of milk.
3. From the 7th day after childbirth, the number of feedings is increased to more than 3 times. The more foods are eaten, the more foods are eaten. If they are fed 4 times, they are available at 5:00, 10:00 and 5:00 and 10:00 in the morning. A total of four times.
4, wet feed can increase food intake 15 ~ 25%, but should pay attention to the following matters:
(1) Avoid feeding water and feed at the same time. If there is too much water, sows will only consume water to eat.
(2) The dry material should be eaten first and then add water, about 1:1 (not more than 1:2), immediately eaten empty.
(3) Wet material did not eat, long-term rancid or did not clean up all had the opposite effect.
(4) If the appetite decreases due to environmental conditions, it should be resolved as soon as possible (15 to 23°C for body temperature control and 16 hours for light).
(5) The amount of drinking water should be sufficient. The pregnant sow needs about 10-15 liters per day. The nursing sows need about 25-35 liters. The flow rate of the drinker should be kept at more than 2000 ml per minute. The water temperature is too hot and too cold to be suitable. Drinking too little water, sows' lactation and feed intake are all affected.
(6) Feed more empty troughs, feed less with full troughs, and maintain appetite.
(7) When the food intake is insufficient and cannot be improved, quickly adopt our recommended high nutrient concentration sow formula and add oil to supplement the necessary fat content.
(8) The digestive rate of lactating sows should be high, which can reduce heat stress.
