Three secrets to making sows more productive and more productive
Three secrets to making sows more productive and more productive? Many people have used these techniques and said yes!
The production performance of the pig farm can't always be mentioned? Sow production management plays a decisive role. To make sows more productive and high-yielding, you can refer to the method. The production of sows can directly affect the interests of pig farms, so farmers want high yields of sows to increase benefits for the farm, but sometimes they are not satisfactory, but there has been no good way. Therefore, today Richi Machinery has put together some methods for farmers to make sows more productive and high-yield, I hope it can help you!
1. Control fat condition, so that the sow has reproductive status
For sows to have more litters and good litters, the sows must have a lean and fat reproductive condition, too thin, undernourished, poor fetal development, poor postnatal vitality, and poor quality; too fat, easy to make Fetal or litter size is low. It is most suitable to keep the condition of sow breeding at 50~70%, and it is best to keep the condition at 60~80% of the whole pregnancy. Therefore, according to the body condition of the sow, increase or decrease the amount of fine feed, so that it has a breeding condition.
2. Take measures to protect the tire
Infected pigs generally have no obvious change in body temperature. The symptoms of dermatitis begin from the corners of the mouth and head, and then spread to the whole body skin a few days later. The skin appears erythema and then develops into a small pustule. After the rupture of the pustule, the fatty exudate flows out, adhering to the dust and dirt, forming a thick scab, which is easy to peel off. The body of the sick pig emits foul odor, which manifests as loss of appetite, weight loss, and may later be complicated by diarrhea and finally exhaustion and death.
9~13 days after sow breeding and 21 days before delivery are prone to miscarriage, special care measures should be strengthened, and rich concentrates such as protein, minerals, vitamins and green and succulent feed should be supplied as much as possible. Avoid feeding frozen or moldy spoilage. Pregnant sows try to avoid mechanical stimulation, such as: crowding, slipping, whipping, startling, etc.
Population on the farm must be recorded in detail to avoid inbreeding. The prevention and treatment of epidemic diseases should be carried out in pig farms, especially the prevention of diseases such as Japanese encephalitis, influenza, brucellosis, etc., and timely treatment of the diseases found. If there is a threat of miscarriage, immediately inject progesterone 15 to 25 mg, and take a sedative to give birth.
3. Strengthen feeding management to ensure the quality of breeding
Breeding quality is directly related to the number and strength of piglets. In order to ensure high yield of sows, after weaning sow piglets, 200 mg of vitamin E can be added to the sow diet. When the sow is nearing the breeding season, it is chopped with half a catty leek every day and stirred in the feed.
For sows with bad estrus, the following drugs can be used to arouse estrus: Angelica 20 grams, 30 grams of radix rehmanniae, Cistanche deserticola, 35 grams of Epimedium, 15 grams of white peony root, 30 grams of echinacea, 40 grams of motherwort, and decoction , The aphrodisiac effect is particularly good.
Breeding sows should be done 24 to 48 hours after the sows start to estrus.
Sows can be fed more fish meal or bean cake within one month after mating, and vitamin E80 mg is added to the diet, which is extremely beneficial to embryo development.
What kind of feed is suitable for sows?
There are currently three main types of sow feed, powder feed, liquid feed and pellets. Powder feed can be divided into two types: coarse powder feeds (simple mixture materials) and commercial fine powder feeds. Liquid feed is a form of feed that has emerged in European countries in the past decade. The purpose is to reduce the use of antibiotics and improve the welfare of sows. With the sharp rise in corn prices in recent years, some customers have realized that the cost of self-ingredients and ingredients is different. In few cases, the demand for compound pellets has increased dramatically, so feed mills have developed to cope with market changes. However, the use of pellets has been controversial.
1. The sow's intake of powder feed is greater than that of pellet feed
The main reason behind this fact is that sows have developed teeth, flexible tongues and large mouths, and the stimulation of the taste and smell of the powder feed makes the secretion of digestive juice in the first phase larger than that of the pellet feed. Salivary amylase has a faster effect on powder than pellets. Therefore, the sow has a stronger appetite for powder feed. In the wild state, the food range of sows is quite wide, including roots and tubers, green feed, cereal seeds, small animals, etc. Mature cereal seeds are very hard, so granular food is not the first choice for sows. In addition, pigs have the habit of rushing to eat, and the consequences of eating large amounts of pellets at a time are very serious: pellets that have not been fully chewed will remain in the digestive tract for a long time, and insufficient secretion of digestive juices in the first period also leads to slower digestive tract peristalsis. Especially in the perinatal period, the decline in sow appetite and the appearance of constipation become inevitable.
2. Powder feed is fresher than pellet feed
As we all know, powder feeds are not easy to preserve and are more easily oxidized; while pellet feeds are different, the area of contact with air after extrusion is reduced, so it can be placed for a longer time. In terms of on-site application effects, powder feeds produced within 3 days are more advantageous (the fewer intermediate links, the better for sows).
After the pellets are produced through the processes of conditioning, extrusion, cooling, grading and packaging, is it the best feed for sows? Because of the economic factors involved, only the following points are explained:
(1) In summer, can the cooling fan cool the newly produced materials quickly?
(2) Can the granulation process achieve effective sterilization? From the aspect of microorganisms, the effect of dry heat sterilization is better than wet heat sterilization, but can the granulation process be achieved? Moreover, the material after granulation has always been half Is the open type transported to the finished product warehouse, is there any possibility of secondary pollution?
(3) For some heat-sensitive substances such as phytase, micro-ecological preparations and vitamins, what is the appropriate level of safety threshold increase? As far as common sense is concerned, as long as it is an enzyme protein, the chance of survival at high temperature does not exceed 10%, then the What does volume add mean?
If the processing requirements of pig feed pellets are not met, then it is obvious that powder feed will be more suitable. It can be seen from the above that for high-tech pig feed factories or pig farms, it is possible to process high-quality pellet feed; however, for many farmers, it may be better to feed sows with powdered feed.
If you want to make mash feed, the manufacturing process: Cleaning -- Crushing -- Mixing -- Packing
Generally,we can divide the raw materials into two parts:one need to be crushed,the other need not.So when we feed material to the feed production line,we will first separately feed them to different channels: particle materials go through feeding port to the pig feed grinder,mash materials go through feeding port to the feed mixer directly.Usually,there are impurities in the particle material,so they will first be put into the pre-cleaner to remove the stones,clods and ropes etc. from them,and the go to the permanent magnetic tube to remove the iron part.The Cleaning system will help you to get the clean material and ensure that there's no unexpected impurities to damage the following feed equipment.
All cleaned materials will be stored and discharged in the bin for the pig feed hammer mill.As the hammer mill is the key machine of crushing system.
Evenly mix different materials into complete mash feed.All materials are mixed together in the pig feed mixer.Usually the volume of the bin for mixer,mixer and the buffer bin are all the same to ensure the mixer can work continuously batch after batch.Please note that the you must make sure the materials every batch in the mixer are accurate to your formula(so you have to weigh the material every batch before feed them to the feeding port.).If it is OK for your budget,you can change for automatic production line to let the computers do this.Premix feed are delivered into the mixer directly because of the small quantity and accurate requirement.
Mash feed(or powder feed) after mixing can be called complete feed now.If you want only to make mash feed,you can send them to the product bin to be packed.
These four processing processes are the sections for processing powdered feed. If you want to process pig pellet feed, you need the following four sections:
Produce final pellet feed. A good pellet means "A complete feed" and a good mill can ensure that.
Extruded feeds are about 70-90° C. Cooler bring down it at normal temperature (+4° max).
To ensure supply of quality and perfect size feed, screener plays a vital role. Uneven sizes screaned-out.
Ready feed need to be packed. It can be manual or automatic bagging depends on requirement.
If you want high sow production, you need to pay attention to all aspects, such as: pre-natal sow conditioning, precautions during breeding, careful management during delivery, post-natal and post-weaning management should pay attention to the sow's life comfort.Then, it will definitely achieve high yield!
