Supply large supply of quality supply sow pig farm

0371-67515075 0371-67510758 a variety of factors in terms of Zhengzhou hundred Yi-Biological Technology Co., Generally choose fattening pigs to be determined according to the condition, size, capital, market and so on. If the market smoothly, export or supply of large cities, we must choose Crossbreed binary, ternary and quaternary pigs (Landrace, Yorkshire, Duroc, Hampshire, Pietrain, etc.), large-scale farming. This pig hybridization has hybrid vigor, grow faster, average daily gain in 800-900 grams, less feed consumption, feed conversion ratio of 2.5: 1, about 60% lean meat, slaughter rate of 72-79%. lower than the general local soil miscellaneous pigs 20-30%. Poor conditions can not be large-scale pig sporadic backyard farmers, to keep the soil × good hybrid generation, or earth × good cross three yuan pig (meat either type). This pig rough-resistant materials, adaptability, reproduction rate, but slow growth of 15-20%, feed consumption more than 16% higher than the good miscellaneous, slaughter rate of about 70% in the 50-55% lean. Second, the factors feeding modalities of a scientific method pig feeding ad libitum intake and regular meals, or 60 kg before ad libitum, restricted feeding after 60 kilograms (limited quality or limit). Diet (diet) may dry feed (scale pig) or wet feed (small number of scattered pig pig). There are a lot of pig farmers to feed processing and boil Hey, this is not only a waste of time, manpower and fuel, and some nutrients (particularly vitamins) are destroyed, not worth the candle. 2, watering food unscientific, the surface pigs eat more, eat belly round, in fact pig swallowed more water, less dry, rapid growth needed to inadequate nutrition, eat more pig gastrointestinal volume more large, affecting the digestion of pigs, circulation physiological functions. 3, can not rationing, hunger and a full meal. Inadequate drinking water, thirsty pigs in the circle only to find dirty water, water to drink urine, it will not only affect the growth and susceptibility to disease. If the lack of drinking water pigs, the reduced feed intake, weight gain decreased. 4, indiscriminate use of additives. Commercially available additives, regardless of what name, the basic ingredients are similar, especially trace elements additives, add more not only a waste of money, but also affect the growth, but also cause poisoning. 5, some pig farmers, regardless of population, large and small, strong and weak captivity in a small weak wronged. Third, feedstuff factors. Nutrition fattening needed are: energy substances (corn, wheat, etc.), protein, fat, minerals, vitamins and water. Pigs at different growth stages, the number and proportion of their nutrition needs are different, those who need their diets formulated feed pigs, pig grow fast, feed efficiency is also high, especially breeding hybrid pigs, for nutrition, management, high-demand conditions, intolerance roughage. But we are many pig farmers based upon traditional methods old pig, so what what feed, feed a single species, even with only a small amount of water scrubbing pots add bran and corn bran feed, there are many pig farmers use a large proportion of meal (pink straw, corn stalks, peanut shells, rice husk powder) pigs, resulting in a serious shortage of swine nutrition. There is a highly nutritious and low nutrition pig comparison test, the result is a high-nutrition group (by raising standards) fed to 150 days to reach 97.25 kg average weight, feed conversion ratio 2.8: 1. When another group meal diet containing 35% (wheat straw), weighing 90 kg, were fed 315 days, feed conversion ratio 5.3: 1.2 group of varieties, premix, feeding and management environment, methods are the same low nutrition group crude protein, energy is not enough roughage and more (crude fiber and more), the results of more than half the growth rate difference. Fourth, environmental factors conditions. Pigpen damp, dirty, feces and urine everywhere, even in the trough have feces, urine, pig in the winter is not warm, summer is not cool, circle no clean comfortable place to rest pigs sleep, potentially increasing Nutritional consumption (pigs standing consume nutrition 9 percent quiet sleep, not to mention irritability), maintenance of nutrition increases for long meat nutritional correspondingly reduced, so grow slowly. Unacceptable temperature on growth, higher than the temperature inside the barn when 25-30 ℃, 10-30% reduction in pig feeding, heart rate, respiration, metabolism speed up, nutrition consumption increases; the temperature exceeds 35 ℃, the pig is not only long, even possible heat stroke deaths; the temperature in the following 4 ℃, the growth rate decreased by 50%, feed consumption increased by 2 times. Test breeding farms in different Sherwin, a 22 kg weight pigs divided into two groups, the test 30 days their growth, feed consumption result is: 22 ℃ average daily gain of 879 g, feed conversion ratio of 2.01: 1; 11 ℃ group, the average daily gain of 766 g, feed conversion ratio of 2.8: 1. If the temperature was 11 ℃ group is below 4 ℃, the results can be imagined what would happen? Cold can also cause disease and death. Fifth, the management factors. First, the construction of ring must choose the right address. According to the requirements of farms, homes to be built in high altitude, the ground was dry, leeward sunny, cool, adequate water, quiet, and convenient transportation, fresh air, easy to control the disease where discounted up outside the house, easy to discharge manure urine. Many pig farmers to be built in the courtyard circle corner, toilet rim, crude, ground slope or did not shop floor, discounted sun not the sun, circle all day moisture, as well as manure pits to stay in the circle, hot days when pigs fight mud, are unscientific. No training pigs eat, sleep, and Latin America "; third positioning."; We can not keep pens clean, dry and clean. Pigs live in an uncomfortable environment, certainly grow slowly. Sixth, disease prevention and control aspects of the factors. In addition to a lot of pig farmers do not pay attention to environmental sanitation, but did not pay attention to the prevention of common diseases, such as anti-colibacillosis (yellow dysentery, white diarrhea, edema), anti-classical swine fever, swine erysipelas, lung disease, piglet paratyphoid, foot and mouth disease, parvovirus, pseudorabies and other vaccine, no time injection. Some pig sick treated in isolation do not know, the big pig sick quickly sell, there's no deep pigs died, incineration, sterilization, but just threw the wild, ditch pond, and even cannibalism or cheap sell butcher family to deal with, did not consider swine infection and themselves, the interests of others. Seven, the traditional concept of. There are a lot of pig farmers affected by traditional ideas, I do not know the physiological and developmental characteristics of pigs, pig raising to more than 100 kg is not sold, to raise to 150-200 kg sold. Crossbreed pig and soil × good hybrid generation or triple, five or six months are up about 100 kg of body weight, before this stage, the fastest growing finishing pigs, less material consumption, good meat, lean meat high, the market Chang market, high prices. If delayed, weighing more than 120 kg, corresponding to slow growth, increased feed consumption, increased fat, decreased lean meat aging. Tests showed that in the 60 kg before finishing pigs lean, fast growth, after 60 kg lean growth slows, can accelerate fat deposition, fat percentage increases. Fattening fat per 1 kg increase nutrition needed the equivalent of pig meat increase the nutritional needs of 2.6 kg, and at present, urban residents have to buy more pork meat, fat tend not to like to eat, resulting in large cities fat meat lowest bid was more than two times, so the pig raising too large, too fat, not low lean, high-fat, feed consumption and more, grow slowly, but also affect the economic benefits of the pig.
