Drying method Natural drying After removing impurities from fresh chicken manure, it is spread on concrete floor or mat, sun dried, sterilized and deodorized. When moisture drops below 10%, crush and bag and store. Heat and dry the chicken manure by 70 °C, 12h, 140 °C, lh or 180 °C, 30min heating; or in chicken manure by adding 30% of industrial ferrous sulfate and mix after placed at 120 °C -160 °C Drying reduces moisture to 10%. Solar greenhouses Mechanical drying A chicken dung is laid in a plastic greenhouse or concrete in a glass greenhouse. The chicken dung is dried by using solar energy and stirring and dehumidifying. High-temperature rapid drying The chicken manure is treated with a high-temperature rapid drier, and the moisture is reduced to below 13% at a high temperature of 500 DEG C to 550 DEG C to fully preserve the nutrient content of the chicken dung. Microwave drying Fresh chicken manure is pre-dried to a moisture content of less than 40%. It is initially crushed and then transported to a microwave heater. Utilizing the microwave source's ultra-high-frequency electric field's thermal and biological effects, it achieves rapid drying, nutrition, and killing. Insects, sterilization and deodorization purposes. Fermentation Natural anaerobic fermentation After removing the impurities, the fresh chicken manure is put into a sealed plastic bag or concrete pool, leaving a small hole for ventilation, allowing the exhaust gas to escape, and keeping the water content between 32% and 38%; controlling the fermentation time varies from season to season. In spring and autumn, 3 months, 4 months in winter, and 1 month in summer, the fermentation stops when the internal temperature of the fermented material is equal to the outside temperature. Oxygenated fermentation Fermented chicken manure (about 1°C, moisture content below 45%) is provided with sufficient air to rapidly propagate aerobic bacteria (eg yeast, lactic acid bacteria). Through the proliferation of bacteria and the temperature, the fermented product decomposes harmful gases such as hydrogen sulfide, which increases the available amino acids and increases the acidity. After stirring and releasing the offensive gas, the powdered feed is dried. Alcohol fermentation Add appropriate amount of soft candy, 10% alcohol and 10% water in fresh chicken manure, mix well, ferment in fermentation tank for 10-20 hours, then sterilize with steam at 100°C; also add 20 in chicken droppings. %-25% of the fresh brewer's grains, mix well and then enter the cement to seal the fermentation for 1 week to obtain a wine-rich product. 2. The spices piled up and fermented in a rectangular concrete floor. According to the proportion (34.2% of chicken manure, 34.2% of grass powder, 28.6% of green feed, 3% of wheat bran, and 25 kg of water and 0.4% of salt per 50 kg of mix), mix evenly. For feed, the water content is held by hand, and it is advised that the water droplets are not satisfactory. The loading pool height is 15-20cm in summer (24h for feeding), 20-30cm in spring and autumn (2-3d for feeding), and 30-50cm in winter (5-7d for feeding). Silage fermentation Fresh chicken manure was treated to a moisture content of about 60%, and impurities were removed, and 50% of chicken manure, 30% of green fodder, and 20% of bran bran were added, and a small amount of salt was added to securely seal in silage or pit. It can be used after 30-45d. Yu Shuqin (1988) made corn manure silage with 40%, 15%, 20% and 25% fresh chicken manure from the harvested corn stalk. The silage with 10% added chicken manure, except for the darker color, has no difference in sensory indexes such as odor, sourness and structure from corn silage silage. Chemical method Propionic acid, acetic acid treatment In the fresh chicken manure, 0.25% of dry manure was added, and 0.5% of them were added with 80% of propionic acid and 20% of acetic acid, and the mixture was fully stirred and then dried. There were characteristics such as ripening, fragrant taste, and palatability. Ferrous sulfate treatment 100 parts by weight of fresh chicken manure, 7 parts of ferrous sulfate (FeS-04.7H2O) and 3.5 parts of coal ash or fine zeolite powder are mixed with each other, and after drying, they become ready for feeding for fish and livestock. Odorless feed. Puffing method The wet chicken manure is first deodorized, dehydrated, and other pretreatments. When the water content is less than 25%, gluten, wheat bran, etc. are added and tempered, and then they are sent to a puffing machine for puffing, which serves the purposes of sterilization, aging, and puffing. . Thermal spraying The chicken manure is pre-dried so that the moisture content is less than 30%, and then it is put into a hot-air jet machine. The material is subjected to a short period of high-temperature and high-pressure treatment and then discharged. Chicken manure and keratin proteins such as feathers, feathers, and dander are mixed in the process of thermal spraying to expand, disintegrate and degrade, which improves the palatability, digestibility, and nutritive effect of the raw material, and at the same time, the puffing occurs. Can achieve further deodorization, sterilization, dehydration and other effects, improve the chicken manure feed value, so that it contains a high protein and a large number of mineral elements of "nontoxic grade" feed. Studies have shown that feedstuffs based on heat-sprayed chicken manure can replace fishmeal. Feeding effect of chicken manure Chicken manure feed pigs and chickens Using 50% chicken dung instead of food and alcohol to feed the pigs after fermentation, the daily gain increased by 2.66% compared with the conventional compound feed, and each grain gain of 1kg saved 2.71kg of grain. He Jian added 15% to 25% of hot-steamed chicken manure in the finisher's diet to replace some of the fishmeal and grains, saving feed costs by 16% to 40%, and significantly increasing daily weight. When Yu Zhisong etc. fed a 20% chicken manure fermented feed instead of the basic diet in the diet, the daily weight gain was 635 g, which was not significantly different from the control group; from feed consumption and economic benefit analysis, the material The meat ratio and the weight gain per 1 kg were 2.7:1 and 4.32 yuan, respectively, while the control group was 3.4:1 and 544 yuan, and the test group was reduced by 1.12 yuan per kg of weight gain cost compared with the control group. The experimental study showed that when the pigs were fed 20-60kg pigs with 10%-30% chicken manure in the diet, the daily gain was 450g, which was 7.7% higher than the control group. l%, while feeding chickens with 60 to 90kg of chicken manure, the average daily gain was 570g, which was 9.4% higher than that of the control group, and the protein content of pork was increased by 10%. -17%, fat content decreased by 40% -82%. After slaughtered chicken feed for 20 days, the meat quality was normal, and all physiological and biochemical indexes were significantly improved. Studies have shown that when pigs are fed with fermented chicken manure, the live weight can reach 85kg at 6 months and the ratio of feed to meat is 2:1. Chicken manure was fed to fattening pigs after fermentation with distiller's grains. Its palatability, daily gain, and economic benefit were better than those of chicken manure distillers. However, there was no significant difference between the whole-period daily weight gain test group and the control group. In the feeds for rearing layers and rearing breeder chickens, the amount of chicken manure used can be set at 20%. After the egg laying peak period, the laying rate is reduced to 85%, and 2% of chicken manure can be added. After gradually increasing to an egg production rate of 55%, the amount of chicken manure can reach 25%, no significant effect on the average egg production, egg production rate, feeding effect is better. Chicken manure feed cattle and sheep Lbehidz reported that chicken manure can be used as a source of nitrogen instead of many raw materials. Buld and Reid also pointed out that about 50% of the nitrogen in dried chicken manure comes from NPN, the CP shows a digestibility of 70%, and the digestive energy value of the fed ruminant is 8.4MJ/KJ. Louise Naluguwa added 0-30% of broiler chicken manure to concentrates for 50 days postpartum on lactating cows for 50 days and had no effect on lactation and milk composition. In China, Yu Boliang substitutes fermented chicken dung for 25%-50% of corn-beancake-type dairy cow concentrates, and its milk production and milk fat content are improved to varying degrees. Feeding from EM fermented chicken dung instead of 50% dairy cow concentrate As a result, the average milk production was increased by 5.6%, and the produced milk had no odor. In addition, Ma Yusheng et al. showed that when dairy cows were fed with 20% chicken manure instead of mixed concentrates, the cows' milk production was higher than that of the control group, and the difference was not significant, but the milk fat percentage was lower than that of the control group. Improve, and the difference is significant. Li Qingwang and other studies have shown that, when beef cattle are used for fattening, 65% of fermented chicken manure is used instead of mixed concentrate, and when aminated wheat straw is used to feed about 150kg of shelf cattle, after 120 days of fattening, the total weight gain of the livestock can reach 1200g. When about 350kg or so slaughtered. The research group of the development and utilization of feed resources is currently feeding Xinong Sano milk goats with pellet feeds containing 10%, 20%, and 30% dry chicken manure. After a 70-day trial, they were fed with dairy goats that did not contain chicken manure. In comparison, there was no significant difference in daily milk yield and daily gain between each group (P>0.05). It was also found that as the proportion of chickens and feces in the diet increased, the feed consumption did not change much, but the feed cost was significantly reduced. When the chicken manure content in the feed was 30%, the cost per 1 kg of milk feed could be reduced by 14.82%. The price of raw materials fell by 23.08%. In addition, AA. Qureshi used chicken manure for sheep diets, reducing the relative cost of raising the sheep by 38.95%. Chicken manure feed fish Shen Guohua et al. used grasses containing 30% chicken manure to conduct grasses and high yield test for squid intensive culture. Compared with all commercial feedstuffs, they were able to feed 22.2% of graded commercial feeds and increased their stocking capacity by 20% compared with conventional feeds. %, the specifications of commercial fish do not decrease. Wang Jiqiao etc. raised catfish and tilapia with 30%, 45%, 60%, 75% and 90% of chicken manure, and compared it with basic feed containing 60% of soybean cake, 30% of bran and 10% of fish meal. The results showed that the use of 30%-60% chicken manure to formulate the feed was better, and the relative daily growth rate (2.18%) and bait coefficient (2.58) were better than that of the basal diet group (1.28%) and (2.67-3.17). . Hu Guohong et al [1994] raised quail with a pelleted feed cage containing 25% chicken manure. The net yield (10.5 kg/m3) was 31.25% higher than the control group (8 kg/m3), and the feed coefficient (2.04) was higher than the control. The group (2.67) was 23.6% lower. Zhu Haiyuan et al. used feed effluent chicken manure as the main source of feed for the cages, raising feed costs by 28.7%. According to Shen Yizhang, the Department of Fisheries and Wildlife of the University of Michigan has added 30% dry chicken manure to pupal feed. After 5 months, the average pupal weight has increased by 2.7 times. In chicken manure-fed goldfish experiment, it has passed 5 In the month, the weight gain of the goldfish in the test group was more than 9% of the control group; the seal farm in Shanghai Jiading County and the Fisheries Research Institute in Harbin City used the chicken manure compound feed to conduct the fish test respectively, and achieved satisfactory results. In summary, because the content of crude protein and amino acid in chicken manure after feed conversion is not inferior to many common feeds other than legumes, it has certain nutritional value and feed value and can be used as supplemental dietary protein for animals, especially ruminants. The feed, however, still has the following problems to solve the chicken manure: The safety of chicken manure is guaranteed; the authoritative basic data that chicken manure can refer to, such as digestible amino acid content data; The improvement of related technologies and equipment for chicken manure feed. It can be expected that chicken manure in this large chicken-raising country will certainly contribute to solving the crisis of protein feed, reducing environmental pollution, increasing resource utilization, and increasing the economic efficiency of enterprises.
