Some stems and leaves of crops are excellent pig feed. Used to feed pigs, not only nutritious, pigs love to eat, but also save feed and reduce the cost of raising pigs. Stem residue from crops that can be used to feed pigs:
Sunflower dish Sunflower dish, a sunflower dish with sunflower seeds removed. In the past, when people harvested sunflowers, they often burned the sunflower plate as waste when the sunflower seeds were threshed. In fact, this is a pity because the sunflower plate can be fed to pigs after processing.
It was determined that in the sunflower dish, crude protein contained 7% to 9%, crude fat was 6.5% to 10.5%, crude fiber was 17.7%, nitrogen-free extract was 43.9%, pectin was 2.4% to 3%, and ash content was 10.1%. The content of crude protein and nitrogen-free extract can be comparable to food. The fragrant fructose contained in the sunflower dish can increase the appetite of the pig.
After the sunflower plate is dried in the sun, it is torn into small pieces by hand, and then pulverized by a grinder to make a sunflower dish flour. With this sunflower meal, the nutritional value per 100 kilograms is equivalent to 60-66 kilograms of corn or 70-80 kilograms of barley.
Because the sunflower dish contains a lot of calcium and more fructose, it is very suitable for feeding piglets and sows. Feeding pigs can promote growth. Therefore, when farmers harvest sunflowers, they must leave the sunflower plate for pig feed and must not be wasted.
Sweet potato vines produce a lot of sweet potato vines during the sweet potato harvest season. If these sweet potato vines are dried in the sun, they are crushed with a pulverizer and then fed to the pigs after saccharification. This becomes a good feed for pigs.
Sweet potato vine powder contains more starch and also contains crude protein, crude fiber, minerals and vitamins, etc., and is a good quality raw meal. At present, many pig farmers mix them directly into concentrates to feed pigs. Although they can save concentrate feeds and reduce the cost of raising pigs, they have low utilization rates and poor palatability.
If the sweet potato vine powder is saccharified to convert the starch into maltose and then used to feed the pig, the utilization rate can be improved and the palatability can be improved.
Sweet potato vinegar powder saccharification method is: the crushed sweet potato vine powder into a clean cask or cylinder, pour 2 to 2.5 times hot water 80 °C -90 °C, and stir into a thick paste; , Cover with a wooden lid, do not allow rapid temperature drop in the barrel or cylinder to maintain the temperature between 55 °C -60 °C; about 4 hours, sweet potato vine powder is saccharification. At this time, sweet potato vine powder is yellow and sweet, so it can be used to feed pigs.
In order to accelerate the saccharification progress of sweet potato vine powder, malt corresponding to 2% by weight of sweet potato vine powder may be added when the sweet potato vine powder is heated and water is stirred. The temperature of saccharification should not be too low, otherwise, sweet potato vinegar powder will not be saccharified and will turn acid. To control the feeding of pigs after the end of saccharification, saccharification in the morning, feed at noon, saccharification at noon, and feed in the evening; even in the winter, saccharification of sweet potato vine powder, storage time should not exceed 10 hours.
The residual grape slag after grape wine grapes are brewed, instead of the corn pasta, the effect is very good.
According to scientific determination, in the dry matter per kilogram of grape slag, it contains 5.7 MJ of digestive energy, 86 g of digestible protein, 13.2% of crude protein, 13.2% of crude fat, 29.4% of crude fiber, 0.67% of calcium, and 0.32% of phosphorus. It also contains a variety of vitamins and trace elements. Compared with corn, 32 grams of more protein per kilogram of digestible protein, 3.7% more crude protein, calcium more than 0.65%, more than 0.09% phosphorus, lysine more than 1.57%. Therefore, in the current situation that the supply of corn is in short supply and the price is high, it is indeed a good method to replace the cornmeal feed with cheap grape slag.
To feed pigs with grape residue, it is better to dry the grape stalks into dried grape stalks and crush them after processing, and replace them with corn hulls to make mixed feeds. The proportion of the mixed feed is generally 10% to 20%. If the proportion is large, it is necessary to add a suitable amount of green and succulent feed.
According to a pig farm experiment, in the mixed feed, about 15% of the dry powder of grape slag is used instead of corn flour to feed the pig. The pigs slaughtered on average can save about 50 kilograms of corn and reduce the cost by more than 20 yuan.
Soybean Leaf Soybean leaves are rich in crude protein and crude fat, and are also rich in calcium and phosphorus. Therefore, in the absence of protein feed, feeding pigs with soybean leaves is an effective way to increase feed protein. There are three specific feeding methods: First, fresh feed. The collected fresh soybean leaves were removed to remove impurities and foreign matter. After being chopped, they were directly mixed into the pig's diet. The amount of feed was about 30% of the diet. For piglets under 30 kg, the chopped soybean leaves can be cooked in pots and fed into the pig's diet.
The second is silage. Soybean leaves have low sugar content and rich protein content. Suitable for semi-dry silage. The method is: the soybean leaves are air-dried to a water content of about 50%, and then rough cut with a knife, and then into a silo, cylinder or plastic silage, compaction seal. When the pigs need to be fed, they are taken out of the diet of the pigs and the amount of feed is about 25% of the diet.
The third is smashing. Soybean leaves are placed in a dry and ventilated place, dried to a moisture content of about 30%, then dried in the sun, dried quickly or placed in a drying room to reduce the moisture content to below 10%, and then pulverized into soybeans using a pulverizer. Leaf powder. This soybean leaf powder can be stored for a long time. When used to feed pigs, they can be directly mixed into the pig's diet, which can account for 20%-40% of the diet.
For soybean leaves used for pig feed, the best period for collection is the soybean wax ripening period. At this time, not only is the soybean leaf greener, it has good nutrition, and its crude fiber content is small, and it will not affect the yield and quality of soybeans.
Whenever the apple leaves fall into the apple clearing garden, a lot of fallen leaves will fall on the apple tree. These apple defoliants have higher nutritional value and can be used to feed pigs.
According to the determination of dried apple defoliation, the internal moisture content was 5.1%, crude fat was 11%, crude protein was 10.8%, nitrogen-free extract was 49.4%, crude fiber was 12.1%, crude ash was 10.6%, calcium was 1.9%, and phosphorus was 0.07. %, and contains multiple vitamins.
Feeding pigs with apple leaves can be concentrated when the apple trees are fallen, removing impurities and rinsing them with clean water. If the amount is small, it can be directly fed into the pig's diet; in order to prevent mildew and deterioration, it can be stored at 0.5 to 1 kg per 100 kg of apple defoliation and stored in the feed pool. When the apple defoliation is stored in the feed pool, it should be layered and compacted, and sealed after filling the pool to ensure the quality of storage. After being stored in the pond for one month, when the apples in the pool are defoliated and fermented, they become soft and slightly yellow in color. When they are slightly scented, they can be used to feed pigs. The palatability is good and the pigs love to eat. During the first feeding, in the first 10 days, the amount of defoliation from apples was gradually increased from 10% of the pig diet to 20%; within the next 15 days, the amount of defoliation from apples was changed from that of pigs. 20% of grain is gradually increased to 50%; then, in another 10 days, the amount of apple defoliation is increased to 60% of the pig's diet, and this amount is maintained.
Feeding pigs with apple leaves can not only make a large number of apple deciduous trees turn waste into treasure, but also save a lot of pig feed, reduce the cost of raising pigs, and increase the economic benefits of raising pigs. After feeding pigs, pigs have good appetite and eat well. Sleep well, good body, skin moist, light, normal growth, average weight per pig per day can increase more than 130 grams, breeding boar can improve semen quality, appropriate fertility can increase fertility rate to 91.1%, production The mother and son were strong after the boy. Therefore, apple deciduous feeding pigs have high utilization value.
Pine needle powder pine needle powder contains abundant nutrients necessary for livestock and poultry, containing 18 kinds of amino acids and various vitamins, trace elements, macro elements, carotene and so on. Feeding 5% to 8% of pine needle powder to feed in the feed can make the pig grow faster, increase disease resistance, and increase economic efficiency.
Pine needle powder is processed from pine needles. Most of the pine trees are evergreen trees, such as Pinus massoniana and Pinus tabulaeformis. The pine leaves are called pine needles. The processing of pine needle powder by itself can be divided into four processes: collection, drying, crushing, and splitting. First, collection. The collection of pine needles can be carried out all year round. Can be combined with pine logging, pruning, etc. for collection. Second, dry. After collecting the pine needles, remove the branches and debris, and spread them in a shaded and ventilated place with a thickness of 5 to 8 cm to allow them to dry naturally. After about 10 days, the water content is reduced to below 12%. Drying equipment can be dried. After the pine needles are dried, their weight accounts for about 50% of the fresh produce. Third, smash. The dried pine needles are pulverized with a pulverizer and sieved, and the powder is a finished product, which is soft and green. Packaging: The processed pine needle powder is sealed in a nylon bag and stored in a ventilated, dry, dark place. It is best to use it while processing to avoid deterioration.
Silkworm rearing mulberry
With the rapid development of the rural sericulture industry, there are more and more leftover mulberry silkworms to eat. The remaining mulberry, which is currently underutilized, is mostly used as fertilizer. In fact, it is a good pig feed that can be used to feed other pigs.
Sericulture leftover mulberry has good nutritional value, including crude protein 17%, crude fat 4%, crude fiber 22.9%, soluble ammonia-free 50%. Mixing these remaining mulberry leaves with other feeds for pigs, the pigs can reduce the consumption of food by 17.5 kg to 20 kg per 100 kg of weight gain.
To use silkworms to feed the remaining mulberry, the first thing to do is to collect the remaining mulberry, spread it out in the place away from the mulberry garden and the silkworm greenhouse, or dry it. If there is lime in it, use a fine sieve to sieve the lime powder. Then, chop with a knife, air dry, package it in a plastic bag, and put it in a dry place.
When feeding pigs with silkworm saplings, proper proportioning should be done according to the weight of the pigs. Usually: 20 to 30 kilograms of heavy pigs, with corn 15%, wheat bran 11.5%, rice bran 14%, silkworm sand l0%, remaining mulberry 7.5%, dried sweet potato 8%, straw powder or sweet potato vine powder l4%, vegetables Seed cake 10%, pea 4.5%, blood meal 2%, fish meal 2%, bone meal 1.2%, salt 0.3%. For 40-90 kilogram pigs, the remaining mulberry can be appropriately increased. The remaining mulberry can be used for 10%, silkworm sand 15%, corn 17%, wheat bran 13%, broken rice 5%, straw powder or sweet potato vine powder 21%, rapeseed cake 10%, rice bran 5%, blood meal 1.5%, fish meal 1%, calcium hydrogen phosphate 1%, salt 0.5%. In addition, add 10 grams of multidimensional pigments, 27.36 grams of ferrous sulfate, and 15 grams of copper sulfate per 100 kilograms of feed.
The yellow mealworm is not only rich in protein, fat, polysaccharid and other organic macromolecular nutrients, but also rich in phosphorus, potassium, iron, sodium, aluminum and other trace elements. For every 100g of the yellow mealworm larvae, the protein content of dry powder is between 48% and 54%, the fat content is between 28% and 41%, and the contents of vitamin E, B1 and B2 are also high. Therefore, the yellow mealworm can provide high quality protein for your starlings, make them strong, eyes bright, feathers rich and shiny.
