Rabbit manure nutrition and fermentation
Rabbit manure nutrition and fermentation
The amount of feces excreted in rabbits is related to their variety, body weight, physiological state, feed composition, and feeding methods. Therefore, the results of measurements across the country are quite different. In 1986, Chen Xuezhi determined that an adult rabbit was fed 120 g of concentrate, 600 g of grass, and 25 g of excrement per day, and about 10 kg of rabbit excrement was produced throughout the year. In 1989, Xu Huai-ran determined that each rabbit produced 60-140 grams of hard manure (grain manure) per day, an average of 100 grams, and about 36.5 kilograms for the whole year. According to the water content of 50%, each rabbit produces about 18 kilograms of anhydrous manure. The former Soviet Union scholar Karyuh (1980) measured the feces output of rabbits of different body weights and different feeding methods. The results showed that the average daily defecation of 93.3 grams of rabbits with a weight of 2.33 kilograms was 3.83 kilograms. Daily feed 110 g pellet feed), the average daily excrement 64.1 g, unlimited feed pellet feed, the average daily excrement was 89.3 g; when the unlimited feed pellet feed, plus green hay powder, the average daily row 98.4 grams of manure.
In 1980, British scholar Elemele et al. analyzed the results of rabbit feces, containing about 19% of crude protein. The United States, "The Practical Rabbit Study" recorded in 1984, air-dried rabbit feces moisture content of 7.9%, dry matter 92.1%, anhydrous rabbit excrement contains 20.3% of crude protein, which can digest crude protein 5.7%, 2.6% ether extract, Crude fiber 16.6%, nitrogen free extract 40.7%, mineral 10.7%. According to the Soviet Union scholar KanyruH's results in 1980, fresh rabbit excrement and its dry matter contained crude protein 7.56% and 13.50% respectively, crude fiber was 13.54% and 31.3%, crude ash was 3.43% and 7.02%, respectively. The extracts were 22.34% and 45.09%, respectively. Containing 0.60% of lysine, 0.23% of histidine, 0.29% of arginine, 0.85% of aspartic acid, 0.37% of threonine, 0.39% of serine, 0.37% of glutamic acid, 0.83% of valine, 0.53 of glycine %, alanine 0.49%, proline 0.53%, isoleucine 0.42%, leucine 1.61%, tyrosine 0.25%, phenylalanine 0.44%. Each 100 grams of rabbit manure dry matter contains vitamin B1229 micrograms, vitamin B61167 micrograms, vitamin PP445 micrograms, vitamin B31796 micrograms, vitamin B1289 micrograms. The fresh rabbit excrement and its dry matter contained 0.46% and 1.01% calcium, 0.40% and 0.88% phosphorous, 0.15% and 0.32% sulfur, respectively, potassium 0.25% and 0.50%, and 0.06% sodium respectively. And 0.12%. It can be seen from the above that the nutrients in rabbit feces are also abundant.
Due to the high moisture content and bad odor of fresh rabbit excrement, it contains a large amount of eggs and contaminants. The fresh chicken manure that has been treated is used directly because of its relative disadvantages. The excess profits and digestive utilization rate are extremely low.
After fermentation of the corresponding bacterium liquid of the Yerida complex microecological preparation, the use of protein can be more than doubled to reach 17% of the available protein content. The conversion rate of other various nutrients can be doubled or more.
1. Ingredients: After the healthy fresh rabbit manure is slightly dried and then shredded (the diseased rabbit manure is not available), press 200 (rabbit feces) : 1 (livestock and poultry) : 1 (brown sugar) plus appropriate amount of water, water 30~35% (According to dry humidity increase or decrease the amount of water) mixed;
Second, the fermentation method:
(1) Anaerobic fermentation
Fermentation vessels can be semi-underground cement pools, ceramic vessels, or semi-underground earthen pits (but with a plastic cloth first) or plastic bags. In all cases, they must be tightly sealed and airtight. Into the water.
Operation mode: The mixture is uniformly and uniformly mixed. The raw materials should be installed 30 to 40 cm above the container mouth, cover the plastic film, and then cover 20 to 30 cm of fine soil, beating tightly to prevent ventilation.
(2) Open container feeding
After the container is sealed, it can be fermented successfully for about 3 to 10 days in the summer and about 15 days in the winter. When it is fed, the dirt and the surface contamination are removed, and the layers are fed from top to bottom. After the feed is used, the pit should be sealed to prevent air and falling into the sand.
(3) Precautions
A. Dilutions of livestock and poultry should be diluted with ordinary brown sugar equal to that of livestock and poultry.
B. The fermented feed of livestock and poultry has distilleries. Most livestock can normally feed without domestication, but few livestock prefer to eat after a few days.
1. The effect of rabbit feces feeding pigs: In 1986, Wang Kejian reported that many farmers in Wuwei City, Gansu Province dried rabbit urine by crushing and then added pigs to the feed. The palatability was good and there was no adverse reaction. Yu Yuqun reported in 1983 that farmers in Donghe County, Jiangsu Province used 102 pigs to be divided into 25 groups in each of the first, second and third groups of the trial and 22 in the control group. The first, second and third groups of the experimental group were added with 10% of rabbit excrement respectively. 20%, 30%, the results of the control group each month average weight gain of 7.5 kg, 24.97 kg of material, 3.33 kg per kilogram of weight consumption. The test group average monthly weight gain of 8.4 kilograms, 18.35 kilograms of material consumption, consumption of 2.37 kilograms per kilogram of weight, one kilogram per kilogram of the test group consumed less 1.92 kilograms of barley. In 1985, Tang Shihao reported that the Shanghai Agricultural College used rabbit manure to feed pigs. The test results showed that the ratio of feed to meat was 1.91:1 in the experimental group and 2.87:1 in the control group, ie, one kg per kg of weight, the experimental group saved more than the control group. Concentrate 0.96 kg. In 1985, Guzi Lin and Zhang Baoqing in 1987 reported that the pigs and feces used in 30% of pig manure ratios in Wanxian and Ganxian counties in Hebei province had similar results.
2. The effect of rabbit feces feeding chickens. In 1986, Wang Ke reported that Li Guozheng, of Wuwei City, Gansu Province, crushed fresh rabbit manure and mixed it with feed to feed chickens. The palatability and effects were good. In 1979, American scientists divided 102 day-old broiler chicks into four groups. The first group was the control group and rabbit feces were not fed. The second, third and fourth groups were the experimental group, and 10% were replaced with dry rabbit feces. 15% and 20% of corn were fed. The energy and protein content in each group were the same during the test period. After 8 weeks of feeding, the average weight gain of each group of chickens was 2131, 2139, 2135 and 2030 g respectively. The difference between groups was not significant. Feed consumption was 3934, 4457, 4572 and 4771 g, respectively, and feed gain ratios were 1.85, 2.10, 2.14 and 2.29, respectively. The slaughter rate (%) was 76.9, 76.8, 76.1, and 76.1, respectively, with no significant difference among the groups.
3. The effect of rabbit feces feeding rabbits: 57 grams of digestible crude protein per kilogram of dry rabbit excrement, equivalent to half the weight of alfalfa hay. After the leaven is added to other feeds, mixed and fed uniformly, or made into pelleted feeds. The Hungarian Veterinary University (1984) used 10 to 15% fermented rabbit feces to enter the mixed feed to make pelleted feeds to rabbits. The effect was similar to that of the control group. In 1989, Sohlolaut fed rabbits with 10% and 15% rabbit feces, which increased carcass weight by 1.9% and 3%, respectively.
4. Effect of rabbit feces feeding fish: Tong Ruicheng et al reported in 1985 that using fermented rabbit feces, mixed with other feeds to make pellet feed, can replace some (20% or so) of fish feed, and its effect is good.
5. Effect of rabbit feces feeding fleas: wolfberry is a high-protein feed, worm feces is a high-quality fertilizer. Therefore, many experimental studies have been done on farmed earthworms both at home and abroad. Japan has accumulated valuable experience on farmed earthworms, and China has done a lot of research on farmed earthworms. In the use of livestock manure to cultivate earthworms have also done some research, Jin Mingxin reported in 1989, cattle, sheep, rabbit feces and rice straw cultivation of earthworms, the effect is better. The proportion of artificially cultivated feed (%) is: cow dung 20, pig manure 20, rotten dry grass and leaves 30, sheep rabbit silkworm excrement 20, hot soil 20. In 1982, Qian Jinkang reported that the proportion of ramie base material was: manure (Pig, sheep, rabbits, cattle, and human feces) accounted for 55%, dry materials (weeds, sawdust, waste paper, garbage) accounted for 45%. In 1987, Ding Luhe reported that Daping No. 2 was cultured with fermented rabbit manure. The mean proliferation rate was 90.73 times in 5 to 6 months, and the average weight gain was 42.75 times. The effect was very good.
After the fermentation of rabbit feces preservation: strict plastic film compression compaction, sealed strictly preserved, as long as the seal is good, generally not degenerate, conditional can buy the appropriate vacuum packaging machine, vacuum packaging of plastic bags, you can save six months Above, and carry on the sale of transportation.
