What kind of feed feed for pigs, and how to feed pig feed with good effect?

The first time available. 1. Master the feeding standards of pigs: pigs with different production purposes and pigs at different growth stages have different requirements for nutrients, so they should choose different feeding standards to prepare diets according to the production purpose, age, weight, etc. of pigs.

2. Reasonable selection of raw materials: When choosing feed raw materials, we must pay attention to the following points: First, pay attention to the type and amount of raw materials.

The variety of raw materials should be diversified to facilitate the nutritional complementarity between various raw materials. The proportion of commonly used pig feed is cereals such as corn, rice, barley, wheat, sorghum, etc., accounting for 50%-70%, bran such as wheat bran, rice bran, etc. out of 10%-20%, soybean cake, soybean meal accounting for 15%-20%, toxic cake, meal such as cottonseed cake, meal and rapeseed cake are correspondingly less than 10%, breeding pigs should not use cottonseed cake, meal. Animal protein feed such as fish meal, silkworm pupa meal, etc. accounted for 3%-7%, grass meal, leaf powder less than 5%, shell powder or stone powder accounted for 3%, bone meal accounted for 2%, and salt should be less.

The second is to pay attention to the characteristics of feed raw materials. It is necessary to grasp the relevant characteristics of raw materials, such as palatability, the content of toxic and harmful ingredients in the feed, as well as the pollution of the feed, whether there is mildew, etc., the amount of raw materials with poor palatability and toxins should be limited, and the raw materials with serious pollution and mildew should not be selected. The third is to attach importance to the principle of economy, and should make full use of local raw material resources in line with the principle of adapting measures to local conditions and taking local materials.

Fourth, pay attention to the volume of raw materials. In order to ensure that pigs can eat the nutrients needed every day, the volume of selected raw materials must be compatible with the volume of the pig's digestive tract, if the volume is too large, the amount of feed required by the pig in a day can not be eaten, so that the nutrients can not meet the needs, and will also increase the burden of the digestive tract; If the volume is too small, although the nutrients are satisfied, the pig does not feel full and shows irritability, which affects growth and development. Third, the processing and modulation should be reasonable

In addition to powdered raw materials such as wheat bran, rice bran, fish meal, bone meal, corn, beans, rice and other seed raw materials should be properly crushed, and raw soybeans cannot be fed directly to pigs, and must be fried or cooked before they can be used. Fourth, the raw materials should be mixed evenly: all kinds of raw materials must be mixed evenly to ensure that the pigs eat the various nutrients they need.

Especially when premixed feed is added, if the mixed feed is not evenly mixed, it is easy to cause pig drug or trace element poisoning. Resources.

2 points are awarded, and the answer is rewarded with bounty points and an additional 20 points. Wish.

1. Pig feed formula (the number in the formula is a percentage, the same below): early stage: corn 25, flour 10, wheat bran 30, vegetable cake 15, cotton cake 13, silkworm chrysalis 5; Medium-term:

corn 25, sorghum 10, wheat bran 20, bran cake 10, bran 11, bean 2, vegetable cake 18, silkworm pupa 2; Late stage: corn 50, sub-flour 10, wheat bran bran cake 10, bean 3, vegetable cake 12, blood meal 2, silkworm chrysalis 5. 2. Trace element formula (refers to the feed content per 100 catties, and pigs can eat more than catty per day); Oxytetracycline 5 grams, copper sulfate 25 grams, ferrous sulfate 15 grams, zinc sulfate 10 grams, dry yeast 35 grams, calcium tablets 15 tablets, cobalt sulfate 30 mg, sodium selenite 5 mg, salt 500 grams.

The above drugs are boiled with boiling water and mixed into the feed. The dry humidity should be kneaded into a ball without dripping, and then stacked and fermented. 15 below the pile for 24 hours, 20 more than 12 hours, more than 30 ready to mix.

Feed 4-5 times a day. The above dosage is the upper limit, and the dosage should not be increased blindly. Note that copper sulfate is hot, and there should be enough water in summer.

3. Application of hormones: Triaconol: water is fed to pigs 3-5 ml per day.

If it is a powder, use it according to the factory instructions. Ninety-two : grams each time, once every three days.

Discontinued 40 days before slaughter. Attached: Shanghai Academy of Agricultural Sciences Institute of Animal Husbandry Test Formula:

Early stage: corn 20, wheat bran barley 15, fish meal cotton cake green sugar 4, green vegetables 50, stone powder salt. It can make pigs gain 483 grams of weight per day; Medium-term:

Corn, wheat bran, barley, fish meal 2, cotton cake 3, green sugar 9, dried vegetables 50, stone powder salt. It can make pigs gain 727 grams of weight per day; Late stage: corn 15, wheat bran 4, barley 10, fish meal 1, cotton cake green sugar dried vegetables 50, stone powder salt.

It can make pigs gain 838 grams of weight per day.

Naturally, it is pig feed, or it is fed directly with rice, and pig feed is generally sold in places where pigs are sold!

Carrots, you add more, you'll eat them, and when you put them away, you can go back and you'll definitely eat a lot.

Personally, I think it should be fed at different ages.

1. Clinker dilute feeding method. The method refers to the method of feeding the pigs with pure water into porridge after the feed is cooked.

2. Wet feeding method of raw meal. The method is before feeding, the powder key pants type broken concentrate, coarse material and other feed, according to the prescribed proportion and total demand with a good match, plus chopped or pulped green feed and water, the general ratio of feed to water is 1, to hold the mixed draft guess the mixture dripping water is appropriate, mix evenly, you can feed the pigs.

3. Dry feeding method. The method is to mix the crushed fine and coarse material evenly in proportion and put it into the automatic trough, so that the pigs can eat freely, and they can be fed once a day, and a water tank is set up to drink water freely.

Feeding pigs with raw meal is faster than feeding pigs with clinker, and the feed utilization rate is also significantly improved. According to the test: the weight gain of piglets fed raw feed can be increased by 12%, and the kilogram of concentrate can be saved for every 1 kg of weight gain; The weight gain of fat pigs can be increased by 35%, and the kilogram of concentrate is consumed less per 1 kg of weight gain.

The following 3 methods are commonly used to feed pigs with raw meal. (1) The raw porridge method washes and chops the green fodder or beats it into a pulp, and the roughage is crushed and fermented, and the concentrate is soaked in cold water in summer and warm water in winter for 2 3 hours. Before feeding, mix the above three kinds of feed well and mix it into a thick porridge (the ratio of feed to water is 1:

3) Feed 3 to 4 times a day. This method is suitable for sows, rack pigs and fattening pigs. (2) After the concentrate is crushed by the raw mixing method, an appropriate amount of chopped green feed or residue feed is added, and the mixture is fully stirred (the ratio of feed to water is 1:

1) Feed 3 to 4 times a day and provide plenty of drinking water. This method is suitable for dry feeding of suckling piglets, weaned piglets or breeding boars. (3) The raw dry powder method mixes the crushed fine and coarse material evenly in proportion and puts it directly into the trough to let the pigs eat freely.

Feed dry powder to another sink to drink, if possible, to feed green feed 1 2 times a day. This method is mostly used to feed fattening pigs. Practice has proved that the effect of dry and wet raw feeding of pig feed is better than that of traditional thin feed feeding pigs.

Because the pigs are fed with traditional pig feed, most of the pigs eat into it is water, which contains little nutrients, and makes the pig's stomach bigger and bigger, not only has damage to the stomach, but also excretes a large amount of energy, consumes more heat energy, and at the same time too much water also dilutes the saliva, can not play the role of enzymes, and the feed utilization rate is low; Many of the vitamins and proteins in cooked feed are destroyed by high temperatures. Cutting, chopping, and cooking food by hand costs labor and fuel, and if the green fodder is simmered in a pot for a long time with a simmer (40 60), toxic nitrite will be formed, and pigs will also cause poisoning. When using wet and dry feed, the soaking and softening of the feed is carried out outside the pig's body, which can shorten the time, and at the same time, the pig's saliva and gastric juice can be fully mixed with the feed, so that it can digest and absorb protein, and vitamins can also be maintained.

Therefore, it is necessary to change the traditional pig feed to dry and wet feeding of pig feed.

The addition of live bacteria Chinese medicine microecological preparations has a good fattening effect, and diarrhea will be cured for a day.

According to the boiled breed, climate and environment, feed quality, etc., many pigs are simple and difficult to raise.

What stage of pigs, you ask?

Here's what you need.

Methods of feeding pigs:

1. Raw feeding and cooked feeding. In rural areas, many pig farmers have the habit of feeding cooked food, believing that cooked feeding can reduce the volume of feed, soften crude fiber, pigs can eat more, and can improve digestibility.

2. Thick feeding and thin feeding. Due to the high water content, the thin soup fills the belly, which leads to the reduction of digestive juice secretion, accelerates gastric emptying, shortens the time for feed to stay in the stomach, and is bound to reduce the digestibility of feed nutrients. Thick feeding, especially raw dry feeding and raw wet feeding, can strengthen the chewing function of pigs, promote the secretion of digestive juices, prolong the time of feed in the stomach and improve the digestibility of nutrients.

3. Eat less and eat more often. The number of meals must be determined according to the type of pig, age, season and feed nature, and cannot be generalized.

4. Timing. Feeding pigs can never be fed late today, feed tomorrow early, and the time of feeding pigs should be fixed every day. This will make the pig develop a habit, when the time comes, they want to eat, and regularly secrete digestive juices, eat particularly fragrant, easy to digest, not easy to make gastrointestinal problems, 5, quantitative.

Feeding pigs a hungry and full meal will make the pig indigestion and slow weight gain.

6. Qualitative. The feed of pigs is best fed with the compound prepared by the regular feed factory according to the feeding of pigs of different types and different stages of growth and development.

There was a difference between raw and cooked feeding, cooked feeding of green and coarse diets was better than raw feeding, the digestibility of dry matter and carbohydrates was also higher in the clinker group, and there was no significant difference in the digestibility of protein and crude fiber. In concentrate-type diets, it is better to feed soybean seeds cooked than raw. However, most of the concentrate type diet, raw feeding is better than cooked feeding, generally after cooking concentrate to lose 5%-10% of the nutrients, raw feed pigs, the average daily weight gain is 10% higher than cooked feeding, each kilogram of gross weight can save kilograms of concentrate, there is no difference in dry matter digestibility, protein digestibility raw feeding is higher than cooked feeding.

In addition, feeding pigs with raw meal can save a lot of labor and fuel. However, some toxic or easily contaminated feeds, such as rapeseed cake, cottonseed cake, swill, etc., can be steamed to detoxify or disinfect.

Master the time to feed the pigs, when is it better to feed the pigs? Pigs are domesticated, pig feeding time should be decided by people, I think regular quantitative, morning, noon and evening feeding is better, can save feed, improve pig feed intake and feed utilization, now farmers feed pigs in two forms, one is regular quantitative, in the morning, noon and evening to feed pigs, more of this feeding method, imitation of more than the best, there is a way to let pigs eat freely, this way is generally used in large-scale farms.

First, regular quantitative, in the morning, noon and evening to feed the pigs.

This feeding method varies according to the season.

1. In spring and autumn, it is generally fed once from half past seven to eight in the morning, once from half past eleven to half past twelve at noon, and once from half past five to half past six in the afternoon.

2. In the hot summer, feed once at five o'clock in the morning, feed once at ten o'clock, feed once at six o'clock in the afternoon, and stagger the hot time at noon to prevent pigs from heat stroke.

3. The weather is relatively cold in winter, feed at half past eight, feed once at one o'clock in the afternoon, feed once at six o'clock in the afternoon, the weather is too cold, the pig is unwilling to get up and eat, and feed when the temperature is high.

Second, ad libitum feeding is generally a feeding method for large-scale farms, this method saves labor, is costly, generally suitable for fattening pigs after weaning, this method has no fixed time, workers start from work in the morning to pour into the trough, until the afternoon off work, pigs eat freely, when they want to eat when to eat.

There is also a method of feeding the hood with large wheels, which is to use different methods according to the pigs at different stages.

1. Fattening pigs are suitable for the above two methods.

2. Sows, pregnant sows are generally twice, from eight to nine in the morning, from four to half past five in the afternoon, three times a week before the conception of empty sows, and the same for fattening pigs.

3. After weaning to before fattening, feed four meals a day, in addition to feeding the same as fattening pigs, and feed once from eight to nine o'clock in the evening.
