Raw feed is more comprehensive than cooked feed. Pigs eat less and grow faster, saving time, labor, fuel and feed. Cooking feed requires a cooker, which not only consumes a lot of labor and fuel, but also increases the cost of raising pigs. At the same time, after high temperature treatment, the nutrition in the feed will lose about 10%. If it is not cooked well, it will also be lost.
Dry and wet feeding is better than dilute feeding. There are three ways to raise pigs: dry feeding, dilute feeding and dry and wet feeding.
Dry feeding, when pigs start to eat feed, they should soak the feed with a lot of saliva, which is harmful to the stomach.
Dilution feeding looks full, but in fact, most of it is water. Too much water is not good for the physiological function of pigs. First, the feed eaten in the stomach cannot rub against each other, which affects digestion and absorption. Second, the feed stays in the stomach for a short time, excretes quickly and digests more heat energy, which affects the growth of pigs. Thirdly, the saliva in gastric juice is diluted, which can not give full play to the role of enzymes, which is not conducive to digestion and reduces the utilization rate of nutrition. The new method of raising pigs adopts soaking and softening dry and wet raw materials, and compares the three feeding methods in practice.
Question 2: What food do pigs eat? It's usually hello!
New pig-raising technology abroad
1. Adding 1.5g calcium formate to the feed a few weeks before weaning can increase the growth rate of piglets by more than 12%, increase the feed conversion rate by 4% and reduce the morbidity of piglets.
Second, the feeding method of sows with more litter. The research method in Germany is: from the third day of weaning, add 200 mg of vitamin E and 400 g of carrot to sow, and the dosage of these two additives will be reduced by 50% until 2 1 day after pregnancy. This method can increase the litter size of sows by 2 1.9%, and the sows and piglets are robust and the survival rate of piglets is high.
Third, feeding baking soda to gain weight Dr. Sticker, an American livestock scientist, found that adding baking soda to lysine-deficient pig feed can make up for the lack of lysine, which is conducive to the digestion and absorption of crude fiber, so that pigs can gain more meat and gain weight quickly.
Fourth, feed trace element copper to gain weight. The latest research in Japan shows that adding trace element copper during the fattening period of pigs can obviously increase the weight of pigs, inhibit the invasion of some germs on pigs and ensure the healthy growth of pigs. If proper copper is added to the feed mixed with antibiotics, the daily gain of pigs can be increased by 6.7%, and the feed utilization rate can be increased by 2-5%.
Verb (abbreviation of verb) Feeding saccharin to gain weight Foreign studies have found that feeding pigs with proper amount of saccharin has a good effect on gaining weight. The method is as follows: adding 0.05g saccharin to each kilogram of compound feed, dissolving saccharin in water and mixing it into the feed can improve the feed intake of pigs and increase the daily gain by 7%. The consumption and cost of pig feed per 100 kg decreased by 4.8% and 3.5% respectively.
Sixth, feeding citric acid to gain weight British research found that adding citric acid to pig feed can increase feed palatability, improve pig's digestion and absorption of nutrients, and improve feed conversion rate. Adding 30 grams of citric acid to each kilogram of feed can increase the daily gain of pigs from 189 grams to 2 16 grams. This method is most suitable for feeding weaned piglets with 5- 10 kg.
Seven, "moving" fattening pigs The experiment of the University of Missouri in the United States shows that changing the number of laps of fattening pigs can increase the appetite of pigs, increase more weight and accelerate growth. However, it is not advisable to change the circle too frequently. It is advisable to change the circle once a month. The size and shape of the circle should be basically the same. Each group of pigs should not be changed or mixed with new pigs at will, otherwise the pigs will feel uneasy and even bite each other.
Eight, feeding oxygen-containing soda to gain weight According to foreign data, weaned piglets are fed oxygen-containing soda every five days 1 time, and piglets gain 200-250 grams a day. Among them, oxygen-containing soft drinks are made by adding a certain proportion of oxygen to ordinary drinking water, usually by injecting 1 liter of oxygen into 1 liter of water. If some additives such as fattening agent can be added to soda, the effect will be better.
Nine, feeding vitamin C to improve quality * * * Germany found that adding 1-4 grams of vitamin C to the feed of boars can obviously improve the quality of boars. In addition, experiments in the United States also proved that adding 1g vitamin C to sow diet one week before delivery can greatly reduce umbilical cord bleeding and piglet mortality.
Question 3: What do pigs eat and grow fast? How to make pigs grow fast? How can pigs grow fast?
1. Are hormones and other harmful substances added to the feed?
This is a question that people are most concerned about but most suspicious. We know that in the past thousands of years, pigs mainly used crops and their by-products as a single feed. Since the reform and opening up, industrial feed with modern significance has been widely used in aquaculture instead of traditional single feed. The industrial feed we are talking about includes not only the single feed produced by industrialization, such as corn and soybean meal, but also the compound feed produced by industrialization. This compound feed is based on modern animal nutrition theory, adding a certain proportion of mixed additives (known as additive premix in the industry) to the traditional single feed.
Feed additives in a broad sense are trace or trace substances added during feed production and use. It mainly includes nutritional feed additives, general feed additives and pharmaceutical additives. Nutritional additives are mainly feed-grade amino acids, vitamins and mineral trace elements (such as copper sulfate and calcium hydrogen phosphate). ); General additives are mainly antioxidants, preservatives, electrolyte balancers, and substances used for coloring, flavoring and anti-adhesion. Ensure or improve feed quality; Drug additives are mainly anthelmintic and bacteriostatic drugs added to prevent and treat animal diseases.
The common characteristics of the above three kinds of feed additives are as follows: firstly, whether a substance can become an additive must be tested and fed by an institution designated by the administrative department of agriculture of the State Council, and experts in breeding, feed processing, animal nutrition, toxicology, pharmacology, metabolism, hygiene, chemical synthesis, biotechnology, quality standards and environmental protection will evaluate its safety, effectiveness and impact on the environment according to the test results. Secondly, the list of substances that become additives is formulated and published by the administrative department of agriculture of the State Council, and only the substances in the list can be fully mixed within the scope specified by * * * to make premix to be added to feed. Third, the added substances listed in the catalogue in China are also internationally accepted and widely used. The safety of adding these substances into feed according to the prescribed method is recognized from the practice of industrial feed breeding in China for 30 years and the wide use in breeding in various countries around the world. Fourth, all additive premixes do not contain substances harmful to human body such as hormones, and there are no drugs such as "sleeping pills" circulating on the Internet. In other words, various substances in feed additives are harmless to the growth of pigs and the quality of pork, and people will not be harmed if they eat these pork.
Second, why should additives be added to feed?
In fact, the traditional single feed is mostly energy feed that can only solve the "food and clothing" of pigs, that is, it can only solve the "food and clothing" of pigs. After adding feed additives, the nutrients necessary for the healthy growth of pigs are supplemented and satisfied, which actually solves the problem of "eating well" for pigs.
Large-scale pig raising must pay more attention to improving the level of disease prevention and disease resistance than free-range pig raising. Adding a proper amount of pharmaceutical additives to feed can effectively prevent and treat common diseases and frequently-occurring diseases in pigs. Moreover, a large number of pig-raising experiments have proved that the permitted drug additives can effectively control the drug residues in pork within the range of * * * which is harmless to human body by implementing the drug withdrawal period in the feeding stage. At the same time, scientific research has proved that the growth of animals needs certain minerals and metal trace elements, just as the human body needs iron, zinc and calcium.
Additives such as antioxidants, preservatives, anti-caking agents and stabilizers are added to feed to meet the needs of industrial and large-scale production of feed, and most of these substances are common additives in food industry, which are harmless to pig growth and pork quality.
Although the existing feed additives listed in the Catalogue are harmless to livestock such as pigs, in order to ensure the safety of livestock and poultry products, the state still strictly stipulates the addition amount of various additives. Generally speaking, the proportion of feed additives in the mixed feed will not exceed 4%, which means that more than 95% of the raw materials in the compound feed are still natural feeds such as corn, rice bran, wheat bran and soybeans. Online saying "100 Jin of grain mixed with dozens of Jin of additives" is sheer nonsense!
Because compound feed is generally granules processed by puffing technology, pigs will drink a lot of water and sleep after eating it, which is a normal physiological reaction of animals, rather than sleeping pills circulated on the Internet. & gt
Question 4: What do pigs like to eat? Grass likes eating sweet potato seedlings.
Question 5: What do pigs in pig farms eat? Feed concentrate first, then feed green feed, and fully mix the saliva (saliva) of pigs with green feed, which can increase the appetite of pigs, eat well, sleep well and grow fast. Concentrated feed is a kind of compound feed with comprehensive nutrition, which can be adapted to local conditions in the vast rural areas, such as corn, rice, barley, wheat, sorghum, sweet potato, etc., and protein feed, such as bean cake, peanut cake, vegetable cake, sesame cake, cottonseed cake, etc., are all called concentrated feed.
Pig's favorite pig grass is grey vegetables, chicken feet vegetables, wheel vegetables and pig sprouts. Pigs also like apples. In order to fatten pigs, you can plant some potatoes and bring them back from the ground in autumn. The big potatoes are reserved for people to eat, and the small potatoes are fed to pigs with pig grass. Spring, summer and autumn are still three months away from winter. Using potatoes to improve the quality of pig food. When the pigs are killed at the end of the year, the fat of the pigs will be pushed up. You can also buy some maifuzi from the farm to make pigs grow more than four fingers.
Question 6: What do wild boars mainly eat? The purpose of keeping wild boar is to give them more space and free exercise, increase their exercise ability, improve their disease resistance and pork quality. It is unrealistic to feed weeds and fruits in batches, and artificial feeding is needed. The feed is mainly corn, and other complementary foods can be determined according to local actual conditions, such as crop straw, fruits and vegetables, bran, etc.
Question 7: What do pigs eat and grow fast? 1, what pigs eat grows fast. To know the fattening effect of additives reasonably, I recommend fattening and weight gain king, who has an excellent reputation.
2. Improve growth performance and reduce feed-meat ratio. Improve immunity and prevent diseases.
3. Promote protein synthesis and bone growth, with an average weight gain of 12%. The whole process is used, and the fattening effect is better.
4. Its main components are = = compound multivitamin, enteric cysteamine, efficient TRIA, active yeast, health care agent for promoting growth and fattening, etc.
Question 8: What do pigs eat and grow fast? 1, pigs grow fast, and the fattening effect of additives is very important. The industry has a good reputation-fattening and fattening.
2, pig technology "backward feeding method" of the specific approach is:
From piglets to middle-aged pigs, that is, before 50~60 kg, concentrate with high energy and high protein was mainly used, and necessary feed additives were added, only a small amount of green feed was fed, and roughage was not fed. When pigs grow to 50-60 kg, they will be slaughtered, and then the energy and protein level in concentrate will be appropriately reduced, the input of concentrate will be reduced, and the input of green and roughage will be increased.
3. The scientific basis of this method is:
Because pigs are mainly long bones and lean meat from piglets to middle pigs, they need more protein and mineral elements. At this time, the digestion and utilization rate of fiber in pigs is extremely low. Therefore, it is necessary to focus on concentrate to meet the needs of pig growth and development for protein and various mineral elements, so that pigs can grow rapidly and reduce unnecessary feed consumption. However, when pigs grow to 50~60 kg, the digestibility and utilization rate of fiber are improved, and the tolerance to roughage is enhanced, so the intake of roughage is increased.
Question 9: Besides pig feed, what food do pigs like to eat?
Pigs' favorite grasses are grey vegetables, chicken feet vegetables, wheel vegetables and pig sprouts. Also like to eat apples! Potatoes are also the favorite of pigs.
The following is a summary of pig feeding behavior:
The eating behavior of pigs includes eating and drinking, and has various age characteristics.
pig
Born with the genetic characteristics of arching soil, arching soil for foraging is the foraging behavior of pigs? Distinctive features. The pig's nose is a highly developed organ, and the sense of smell plays a decisive role in digging the soil to find food. Although in modern pigsty,
Feeding a balanced diet, pigs also show the characteristics of arch foraging. Every time they are fed, pigs try to occupy the trough.
Favorable position, sometimes put two forelimbs in the trough to feed, if the trough is easy to access, individual pigs will even drill.
The feeding trough, standing in the corner of the trough, is like a wild boar arching for food, arching along the trough with a kiss and stirring the food all over the floor.
Pigs are selective in their intake of food, and especially like sweets. The study found that non-breastfed newborn piglets like sweets. Compared with powder, pigs like to eat granular substances; Compared with wet feed, pigs like to eat wet feed and spend less time.
pig
Our breeding is competitive. Pigs fed collectively eat more, eat faster and gain more weight than pigs fed alone. The pig is dressed in white.
Feed 6 ~ 8 times a day, which is 1 ~ 3 times more than at night. The duration of each feeding is 10~20min, and the limited feeding time is less than 10 ~ 20min.
Free feeding not only requires long-term feeding, but also shows the hobbies and personality of each pig. Piggy every day
The frequency of night smoking varies with age, ranging from15 to 25 times, accounting for10% to 20% of the total day and night time. The feed intake and frequency of big pigs increase with the increase of body weight.
Question 10: What is the best feed for raising pigs? "Six Persistences" in Scientific Pig Raising
First, insist on raising hybrid pigs.
Piglets produced by Duroc, Bitran, Dika, Landrace and other boars. And local sows are called hybrid pigs. The first generation of hybrid pigs has strong viability, fast growth and good feeding effect. Therefore, it is necessary to popularize the new technology of "three modernizations" of hybrid generation of improved boar, localized sow and piglet.
Second, adhere to the implementation of protective feeding.
In summer and autumn, cucurbitaceae, pumpkin, sunflower and other plants can be planted outside the pig house to shade the sun and cool down. In winter, we should popularize the new technology of feeding in plastic greenhouse, and do a good job of deworming and immunization regularly.
Third, adhere to the law of self-cultivation.
Raising excellent breeding boars, hybrid piglets and commercial pigs is conducive to preventing epidemics, improving the survival rate of piglets and reducing the cost of raising pigs.
Fourth, adhere to the implementation of high-density pig raising.
0.8m2 pigpen in winter 1 fattening pig, summer 1 pigpen 1 fattening pig. Because of intensive pig raising, saving pig houses, less investment in fixed assets, competition for food by fattening pigs, small activity space, sleeping after eating, rapid weight gain and shortened feeding cycle.
5. Insist on seeking benefits from science and technology.
Carry out the one-stop rapid pig raising method. Implement "five changes and one increase", that is, change fat pigs into lean pigs such as Landrace, York and Duroc. Second, feed a single feed instead of a matching full-price feed. Thirdly, the clinker feeding is changed to raw meal wet feeding. Fourth, change the hanger fattening into linear fattening. Using linear fattening method for weaned piglets can effectively shorten the fattening period, improve the fattening rate and increase economic benefits. Fifth, call the veterinarian for early prevention if there is no disease, and strictly control the four major infectious diseases, namely swine fever, swine erysipelas, swine lung disease and paratyphoid fever, so as to reduce the mortality rate and improve the survival rate and slaughter rate. One plus is to add additives and auxin.
Six, adhere to the timely slaughter and slaughter.
When the weight of fattening pigs exceeds 90 kg, the daily gain rate slows down obviously, and fat deposition is the main factor, so the more you feed, the less cost-effective, and the more fat you increase, the more you can't sell it. Although the feed utilization rate is high, it is uneconomical because of its small weight and low meat production rate. Generally, it is most suitable for slaughtering fattening pigs weighing 90 ~ 120 kg.
Scientific pig raising method-backward feeding method
In rural areas, most farmers still continue the traditional way of raising pigs, that is, using the "hook" feeding method. In the early stage, a large number of green and coarse feeds were fed, and only a small amount of concentrate feed was put in. When pigs grow to 50-60 kg, add a lot of high-energy concentrate to fatten quickly. Although this feeding method uses a lot of green feed and roughage, it can't meet the demand for protein and mineral elements in the early growth stage of pigs, which leads to the slow growth of pigs and the prolonged slaughter time, which usually takes more than one year, greatly increasing the consumption of feeding and maintenance. This feeding method not only fails to save concentrate, but also causes a lot of waste of concentrate.
However, a small number of pig farmers adopt a "one-stop" feeding method, that is, from piglets to slaughter, they have been fed concentrate without adding any green feed or roughage. Although this method greatly shortens the feeding cycle and reduces the maintenance and consumption of feed, a large number of green roughage in rural areas have not been fully utilized, so the economic benefits are still not ideal.
Using "backward feeding" to raise pigs can effectively avoid the disadvantages of "hook" feeding method and "one-stop" feeding method, saving concentrate by 30% and 10% respectively compared with "hook" feeding method and "one-stop" feeding method, and the lean meat rate of pigs is high, which is very popular with consumers. The specific practice of "feeding pigs backwards" is:
From piglets to middle-aged pigs, that is, before 50~60 kg, concentrate with high energy and high protein was mainly used, and necessary feed additives were added, only a small amount of green feed was fed, and roughage was not fed. When the pig grows to 50-60 kg, the energy and protein level in concentrate will be appropriately reduced, the input of concentrate will be reduced, and the input of green feed and roughage will be increased, with the ratio of concentrate 62%, green feed 26% and roughage 12%.
The scientific basis of the "backward feeding method" for raising pigs is: because pigs are mainly long bones and lean meat, they need more protein and mineral elements, and at this time, the digestion and utilization rate of fiber is extremely low, so it is necessary to focus on concentrate to meet the needs of pig growth and development for protein and various mineral elements, so that pigs can grow rapidly and reduce unnecessary feed consumption. However, when pigs grow to 50~60 kg, the digestibility and utilization rate of fiber are improved, and the tolerance to roughage is enhanced, so the intake of roughage is increased. ...& gt& gt
