How to efficiently raise pigs to save feed
First, choose excellent hybrid combinations, make full use of heterosis
As the saying goes: "Catch the pigs, look at the pigs." "Excellent is not good, look at the mother and mother." That is, to choose the fine variety and the best hybrid combination. If you want a fattening pig with a good meat quality, a moderate lean meat rate, and a fast-growing pig, you should choose a “soil three-yuan†hybrid pig, that is, a local pig as the female parent and a long white pig or a roughly gram pig as the first male parent. The "Duo Chang Ben" or "Du X Da· Ben" hybrid pig produced by Duroc as the second father.
If you want to grow fast, lean meat, and fattening pigs with poor meat quality, you should choose "Yang Sanyuan", "Du × Chang·Da" or "Du × 大·长" hybrid pigs.
Large and medium-sized pig farms can consider breeding commercial pigs in the matching department, because this pig combines the advantages of several varieties and has greater heterosis.
In short, the stronger the heterosis, the stronger the viability, adaptability, and disease resistance, and the faster the growth and development.
In addition, the offspring of the young and the sows have strong viability, so there is no special need, and pigs over 6 years old should be eliminated. The same litter pig, born with a large body, grows fast, saves the feed.
Second, do a good job of feed, develop feed resources
"Pig is a mouthful of goods, can not eat can not be hungry." Only by supplying sufficient nutrients can normal growth and development be promoted. The general feed formula for growing fattening pigs is: corn (2417, -9.00, -0.37%) (or barley, sorghum, secondary powder, etc.) 60%, soybean meal (3358, -71.00, -2.07%) (cooked) 18 %, bran 15%, premix 5%, other 2%. Under the premise of meeting the nutritional needs, we should look for high quality and cheap feed to significantly reduce feed costs.
Fecal feed. The chicken manure produced by the chicken manure feed compound feed is a high-protein supplement feed with an average of 27% crude protein. The growth and fattening pigs are added 30%, and the feeding is not limited, which does not reduce the growth rate, but greatly reduces the feed cost. Cow dung, especially the cow dung produced by compound feed, has similar nutrition to millet rice. Generally, cow dung can account for 10% to 15% of pig feed. Pig manure contains 19.0% of crude protein (of dry matter). Generally, 10% to 15% of pig feed can be added. Rabbit feces include soft feces and hard feces. Soft feces are of great nutritional value, but almost all of them are eaten by the rabbits themselves. Only hard feces can be collected for use as feed. The dry matter in rabbit hard feces contained 16.7% crude protein. Rabbit feces generally account for about 25% to 30% of pig feed.
Green feed. The green-green feed has many water content, soft and crisp texture, and rich in nutrients. It can make up for the lack of nutrition of concentrates such as corn. Green-green feed beating or feeding or silage can be fed. High-quality green and green feeds include sweet potato vine, alfalfa, sand sorghum, leeks, chicory, bitter cabbage, carrot stems and leaves. The addition of greenish feed accounts for 5% to 10% of the pig feed (dry basis). In order to ensure the supply of green feed, it is recommended to raise grass and raise pigs.
Dregs feed. Such as vinegar, bean curd residue, powder residue (beans, potatoes), distiller's grains, sugar beet residue, sauce residue, sucrose filter mud. This kind of feed is rich in protein and low in price, and is a good raw material for fattening. The 8% sucrose filter was added to the diet to feed the pigs, and the daily gain and feed remuneration were basically the same as the control group.
Non-toxic leaves. In principle, all non-toxic leaves can be used as feed for pigs, but leaves that have been sprayed with chemical pesticides cannot be used. Commonly used leaves are locust leaf powder, amorpha leaf powder and pine needle powder. Both the hedgehog leaf powder and the amorpha leaf are high-protein supplemental feeds, generally 2% to 10%. Pine needles are made into pine needle powder, and 4% to 4.5% is added to the growing pigs, which can increase the weight gain by 15% to 30%.
Waste from the slaughterhouse. The waste from the slaughterhouse can be used as feed if it is not edible and contains certain nutrients, but it must be cooked after cooking, generally accounting for about 40% of the diet.
In addition, it is necessary to change the feeding method of the thin belly, and generally promote dry feeding or thick feeding. In addition to beans and potatoes, other feeds are fed. Raw feeding can maintain more nutrients and will destroy many nutrients after cooking. At present, there are still a small number of farmers who cook the mixed feed with water, which is a serious waste phenomenon.
Third, optimize the living environment of the herd
Preventing noise - Because pigs are very sensitive to hearing, they react more strongly to noise, especially sudden highs, which can seriously affect their weight gain.
Prevent bad smells - odor, soot, ammonia and other bad odors can affect the health of pigs.
Preventing visitors from visiting a 10,000-headed pig farm. If a visitor is accepted, the pig's eating will be reduced due to the smell and speech of the person, which may cost about 2,000 yuan, so it is strictly forbidden to visit.
To plant trees for afforestation - afforestation can regulate temperature and reduce harmful gases, odors, dust and bacteria in the air.
Pigs are smarter animals. In the case of large groups of pigs, light music or watch TV should be placed when conditions permit. Small balls can be hung above the pig pen to play.
In addition to the above-mentioned technologies, we must conscientiously implement the purification and immune deworming of pigs; build pig houses that are warm in winter and cool in summer; measures such as timely castration.
