What if the sow does not eat? Method for increasing feed intake of sows
The low feed intake of the sow will indirectly affect the economic benefits of the pig farm, because the low feed intake of the sow will lead to insufficient milk, constipation, low estrus after weaning or delay in estrus, and the lack of milk will cause the piglets to survive. The low rate and slow growth are not conducive to fattening. Therefore, improving the feed intake of sows is a problem that farmers must try to face.
First, precautions before feeding
The weather in the south is still hot and the feed intake of sows has not been able to go up. What details should the farmers pay attention to before feeding the sows?
1. Feeding the trough before and after feeding
In hot weather room, the temperature is relatively high. You can scrape the remaining water and leftover material of the sow trough 1-2 hours before feeding each meal, and then add cool ground water or cool tap water in the sow trough. Try to let the sow drink plenty of water within 1-2 hours before feeding.
2, pay attention to temperature
The sows that are cooled, ventilated, ventilated, and have no childbirth before the sow is fed can be drenched and cooled before feeding. The heat at noon and afternoon can be appropriate to pour some cool water on the top of the sow. Cool down, drench for 2 hours and drip on the top of the sow. Sows that have already given birth are not recommended to drench water on the sow. In order to avoid making the bed of the production bed and the delivery room too humid, you can open the water in the roof of the delivery room, pull the shade net, and open the facilities in the delivery house, such as fans, air coolers, water curtains, air conditioners. The exhaust fan, of course, the pig farm with temperature control facilities is even better.
  3. Feeding the sows with signal stimulation
Take a shovel or a feeding spoon before feeding, and knock on the walkway in front of the sow to stimulate and arouse the excitement of the sow. When all the sows stand up and know that they are feeding more and more Big time is the best time to feed.
Second, the feeding method and time to grasp
1, feeding time and feeding times
A large-scale pig farm in the south feeds pigs at 6 o'clock in the morning, and feeds two meals a day from 17:00 to 17:30. In the morning, the weather will be slightly cooler. The feed intake of the sow will be higher than other time periods. In the morning, the sow will be fed 4-4.5kg. The sows with good appetite and large size can eat 4-4.5kg in the morning, and the afternoon will be late. Feeding at 3.5:30 is 3.5-4kg.
  2, the control of feed amount
With the improved crossbreeding of domestic and foreign varieties, the sows are getting bigger and bigger. In the past, the traditional feeding methods have not been able to meet the needs of the sows. Therefore, it is necessary to further adjust the feeding methods of the sows. Pay attention to the following points in terms of feeding amount:
1 Sows who want to eat during childbirth are advised not to feed on the day of delivery.
2 The sows with large body and good appetite on the first day after delivery will be fed 1.5kg/day, and will increase by 1-1.1kg/day from the next day. According to this feeding method, the sow will be on the 7th day. Can eat 7.5-8.1kg of feed, 7 days after the sow freely feed. According to this feeding method, sows can eat 8.5-9kg/day or more in 8-21 days. On average, each sow can eat 6.023-6.385 kg/day for 21 days, as long as the time is good. No problem.
Sows from the spirit and young sows appetite general not recommended day feeding (only bran + + add water inside the chute brown sugar) or fed 0.75kg / day feed from the first day increasing daily 0.75-1kg / day. According to this feeding method, the sow can eat 6-6.5 kg of feed on the 7th day, and the sow can eat it freely after 7 days. According to this feeding method, the sow can eat 7.5-8.5 in 8-21 days. Kg/day, even more feed can be eaten, an average of 21 days per sow can eat 5.285-5.97 kg / day, this feeding method is also feasible.
3 Feeding should be flexible When it is found that individual sows can't finish the feed in the morning, they will feed less in the afternoon; the same reason is that when the amount of sows fed in the afternoon is not enough, the next morning will be fed less. It is also not recommended to feed the same amount of feed in the morning and afternoon. In the morning, try to let the sow eat more. In the afternoon, the appetite of the hot sow will be worse than the morning.
4 After the feeding and feeding, feed the first time in the trough, wait until the sow eats two-thirds of the feed or when the feed is about to be eaten, then add the second feed and add the second water. Then mix the feed and water evenly by hand or with a tool. The feed can be mixed with some sows and will prefer to eat.
Why do you recommend that the feed be wet? On the one hand, the hot sow's appetite is relatively worse than that in autumn and winter. If the feed is too dry, the sow will not want to eat it. On the other hand, the sow feed will be mixed with groundwater or cool tap water. This will increase the palatability of the sow and feed more feed than the original feed. Under normal circumstances, it is customary to leave two or three sows with a small amount of feed when feeding sows, and wait until the remaining feed of other sows is scraped out and eaten for these two three sows, so that there is very little leftover. The situation that the sow can't eat.
Third, the details of the sow feeding attention
1. After feeding for 1 hour, scrape the leftover material.
When some sows are half eaten, the piglets are fed around the sows. At this time, the sows will fall asleep and wait until the piglets have finished eating the milk, and the sows have not really fed the feed. The sows stand up again to feed. The feed that stays in the trough for a long time in the weather is prone to acid deterioration. After feeding the feed for one hour, the remaining material in the trough must be scraped or the trough should be cleaned. Some breeders don't shave the sow troughs and don't shave the sows. They think that the sows will eat when they are hungry. This will easily cause the sows to eat less, or often eat no meals. Then go to the treatment and do not eat and injection, resulting in a vicious circle. Therefore, it is recommended that the feed be cleaned out of the trough one hour after the sow is fed, regardless of how much feed is left in the trough, to prevent the piglets from eating too much spoiled, sour sow, causing indigestion in the piglets. Dilute, also to avoid the mold sticking to the mold wall mold, deterioration affects the appetite of the sow and reduce the soy toxin of the sow.
2, the bar
In the pig farm delivery room is a relatively simple bar, must be washed once a day, usually in the morning to feed the sow, after the health is done well, the column is washed, 7-8 o'clock in the summer morning, early rush The column allows the fan to dry the floor of the delivery room to avoid the formation of high temperature and high humidity in the delivery room.
Hot weather is the main reason for the decline in sow feed intake, but reasonable feeding methods and measures such as cooling the pig house can greatly increase the feed intake of the sow.
