Management of sows at weaning? 20

When weaning piglets, it is necessary to recover the sows as soon as possible.

Feed nutrition should be comprehensive, add live bacteria and traditional Chinese medicine microecological preparations to regulate the sow intestine, improve the feed intake of sows, improve immunity, and promote sows to recover productivity better and faster.

In this process, we must form a good feeding environment, clean up the pigsty in time, and according to a certain feeding density, classify and feed piglets of different sizes, eat some more nutritious feed, and add clear grain feed in time.

There are key points such as temperature control, feed ratio, environmental maintenance, management personnel to be consistent with before, and density to grasp well, only by mastering these can we better transition management.

It is necessary to pay attention to the balance of nutrition, the addition of feed, and the matching of fine grains, which can better ensure the absorption of nutrients, and pay attention to the digestion of piglets.

Be sure to strengthen nutrition, choose foods that are easy to digest, never use too many hormone products, relieve the mood of piglets, and reduce stress.

Prevent weaning stress.

1. Feeding method: when weaning, it is necessary to go to the mother and keep the young, and keep the environment, feed and breeder unchanged.

2. Health care methods: 5 days before weaning to five days after weaning, add Gaolin, piglet-type Jiante, and strong vitamins to the feed.

3. Benefits: 1) Induce immune factors, activate macrophages, produce interferon, and promote antibody production.

2) Oligosaccharides are the direct nutrition of beneficial bacteria, so that the beneficial bacteria in the intestine can multiply rapidly, occupy the intestine, and improve the antibacterial ability.

3) Soluble dietary fiber, which can promote gastrointestinal motility, enhance digestive function, improve feed conversion rate, and reduce nutritional diarrhea.

4) Compatible with antibiotics, it can prevent and treat viral diarrhea in difficult cases where antibiotics are ineffective.

5) The role of Gao Lin.

6) Supplement the vitamins needed for the rapid growth of piglets.

After weaning, give the piglets quality easy-to-digest feed, raise the temperature, keep them dry, and reduce stress!

A health check and individual identification of the sows are carried out in the week before weaning, individual sows are decided to be culled after weaning, and most sows are prepared for weaning. Before weaning, the farrowing pen should be used to protect the effect of pigs, and the trauma and foot and leg disease of pigs should be actively and effectively carried out, and the ear number or ear tag should be trimmed and perfected.

There may be a small number or individual sows that need to be lactated for an extended period and should continue to be adequately reared; Other sows start to feed down two days before weaning, reducing the amount of feed by 30% to 40% per day, and by the day of weaning, the feeding amount is about 1 kg.

At weaning, the body fat of the sow was evaluated, and the farrowing and lactation performance of the sow and the production performance of this breeding cycle were summarized. The sows that are ready to be culled are transferred to the culling barn, and the other sows are transferred to the breeding barn.

Rational grouping: empty after weaning.

Sows can be fed in groups, 3 to 5 sows per pen. The sows are fed in groups according to size, strength and fattening, and each sow occupies an area of at least 2 square meters. Provide a suitable environment for weaned sows:

The temperature of the pig house should be kept at 16 25 and the relative humidity of 70% and 80% is appropriate. In summer, take appropriate measures to prevent heatstroke and cool down. In the cold winter, in addition to doing a good job of thermal insulation, it is also necessary to ventilate regularly to prevent excessive ammonia smell in the pig house.

Keep the enclosure hygienic, clean and dry.
